T E C H N I C A L M A N U A L M LC P S Y S T E M 0 8 / 2 0 0 9 3 The Uponor MLCP system 4 Basis for your professional installation The complete system from one source Tested Quality Permanently watertight, together with a long service life, are the most important requirements that are demanded today from a reliable and high-quality installation. Uponor as a leading manufacturer of plastic pipes for house construction and municipal technology fulfils these requirements without reservation with its Uponor MLCP system. With this system we offer you the security that is so important for your installation. Whether it is tap water or radiator connection – the Uponor MLCP system is the perfect solution. The comprehensive program permits the complete installation from the house connection line to the consumer. The installation is simple and economical: The core of the system, i.e. the Uponor Unipipe MLC pipe and the relevant fittings, are manufactured in house and therefore perfectly coordinated. Through the inherent stability of the pipe and the low linear expansion, only a few fixation points are necessary – the practical advantage for a safe and fast installation. The Uponor MLCP system is rounded off by a well thought out Tool program: from pipe cutting tool over bevelling tool up to pressing tools. With the Uponor MLCP system you install tested and certified quality. Thus you observe all required building regulations, including fire protection, sound protection and thermal insulation regulations. The system technology is also here particularly long-lived and safe, certified by numerous tests and licences. T E C H N I C A L M A N U A L M LC P S Y S T E M 0 8 / 2 0 0 9 The Uponor Unipipe MLC pipe – a well thought out development Construction of the Uponor Unipipe MLC pipe PE-RT Adhesive Adhesive PE-RT Longitudinal safety welded aluminium pipe 5 layers – built for the future With our 5 layer composite pipe we developed a product with a future, which combines the benefits of both metal and plastic pipes. Product benefits are obtained that cannot be surpassed: The inner aluminium pipe is absolutely safe against oxygen penetration. It compensates for the snap-back forces and the linear expansion caused by temperature changes. The basis of the system is simple, safe and fast pipe installation: simply bend by hand, cut to length, bevelling, join together, press – done! The Uponor Unipipe MLC pipe consists of a longitudinal safety welded aluminium pipe, to which an inner and outer layer of high temperature resistant polyethylene is applied (in accordance with DIN 16833). All layers are permanently bounded together by means of an intermediate adhesive layer. A special welding technique guarantees a maximum of safety. The thickness of the aluminium selected for the Uponor Unipipe MLC pipe is exactly adapted to the compressive strength requirements as well as the bending capability. Benefits Absolutely oxygen diffusion tight multi-layer composite pipe Available in dimensions 14-110 mm Easy handling Low weight High inherent stability and bend flexibility Low linear expansion Excellent hydrostatic stress performance Corrosion resistance The best insulation PP PB PVC Unipipe Copper Galvanized steel Stainless steel T E C H N I C A L M A N U A L M LC P S Y S T E M 0 8 / 2 0 0 9 The Uponor Unipipe MLC pipe has a comparatively low linear expansion due to the plastic film‘s firm bond to the aluminium The Uponor Unipipe MLC pipe for tap water installation and radiator connection can also be ordered preinsulated. You have an assortment available in sizes from 16-25 mm that fulfils all insulation requirements of DIN 1988-2 and the German Energy Saving Directive (EnEV). The pre-insulated pipes save installation time because the time intensive insulation of the mounted pipes and the resulting gluing of joints are much reduced. 5 The resilience of the multi-layer composite pipe is checked regularly by tensile testing. Along with the continuous laboratory testing of the pipe, each Uponor Unipipe MLC pipe is checked during production for accuracy of size and water tightness.

The short-term malfunction temperature is 95°C of a maximum of 100 hours in the operating lifetime. Heating: The maximum permanent operating temperature is 80°C at a maximum permanent operating pressure of 10 bars*. The short-term malfunction temperature is 95°C of a maximum of 150 hours in the operating time per year. * In some special products the permanent operating pressure is lower than 10 bars. Please have a look on the pipe marking. In case of exceeding the maximum permanent operating temperatures e.g. in solar systems or district heating systems, the Uponor MLCP system can’t be connected directly to this kind of systems. It has to be ensured that in every situation the maximum limits of use of the Uponor MLCP system are not exceeded. In case of other use of the Uponor MLCP system Uponor has to be consulted. 6 T E C H N I C A L M A N U A L M LC P S Y S T E M 0 8 / 2 0 0 9 Zeta values and equivalent pipe lengths A flow rate of 2 m/s has been used for the calculation of equivalent pipe lengths: Dimensions OD x s [mm] Inner diameter ID [mm] Zeta values ζ (-)/ equivalent Pipe length eL [m] 14 x 2 16 x 2 18 x 2 20 x 2 25 25 x 2.5 32 x 3 40 x 4 50 x 4.5 63 x 6 75 x 7.5 90 x 8.5 110 x 10 10 12 14 15.5 26 32 41 51 60 73 90 Press elbow 90° 7.0 2.5 4.4 2.0 3.6 2.0 3.0 1.9 2.8 2.4 2.3 2.7 2.0 3.1 1.6 3.3 1.4 3.8 1.4 4.6 3.7 15.4 2.9 15.5 Press elbow 45° - Reducing 2.8 1.0 1.7 0.8 1.4 0.8 1.2 0.8 1.0 0.9 0.9 1.1 0.8 1.2 0.6 1.2 0.6 1.6 0.5 1.6 0.5 2.1 0.7 3.7 Branch at flow split 8.3 3.0 5.2 2.4 4.2 2.3 3.6 2.3 3.2 2.7 2.6 3.1 2.4 3.7 1.9 3.9 1.7 4.6 1.7 5.6 3.7 15.4 2.9 15.5 Branch run at flow split 2.0 0.7 1.2 0.6 1.0 0.6 0.8 0.5 0.8 0.7 0.7 0.8 0.5 0.8 0.4 0.8 0.4 1.1 0.4 1.3 0.5 2.1 0.4 2.1 Branch reverse run at flow split 7.3 2.7 4.6 2.1 3.7 2.0 3.2 2.0 2.9 2.5 2.3 2.7 2.1 3.2 1.7 3.5 1.5 4.1 1.5 4.9 2.2 9.1 1.7 9.1 ζ eL - ζ - eL - ζ - eL - T E C H N I C A L M A N U A L M LC P S Y S T E M 0 8 / 2 0 0 9 ζ - 20 eL - ζ eL ζ eL ζ eL ζ eL ζ eL ζ eL ζ eL ζ eL 1.5 1.3 1.2 1.4 1.2 1.8 0.8 1.7 0.8 2.2 0.8 2.6 0.7 2.9 0.6 3.2 7 Fast, simple, safe: The connection technology for Uponor Unipipe MLC pipes Extensive program from a single source Uponor shows its strength in the development and manufacturing of a fitting concept precisely coordinated to the pipe being used. The pipe fitting program with its couplings, elbows, T-pieces and large number of practical system components satisfies your every need: Pressed or compression – both methods can be used and ensure durable watertight connections. The flexibility of the Uponor Unipipe MLC pipes can often reduce the number of elbows needed for the installation. This substantially lowers material costs as well as reducing installation time. Further benefits are shorter fitted length and an increased installation safety. Even with complicated applications you find the right connection in Uponor‘s extensive fitting program – whether press or compression. Uponor MLC press fittings Connections can be made within seconds with the patented Uponor press system. Complicated connection techniques such as a welding or soldering are not necessary. The connection technique produces permanent watertight press and compression connections, as is confirmed by the SKZ test reports and DVGW certificates.

Pressed into the inner plastic layer of the pipe, the special profile of the PPSU insert produces a reliable connection. A hightemperature and age resistant O-ring fitted into a groove provides sealing between the insert part and inner wall of the pipe. After installation the form-stable press sleeve allows the connection to absorb bending forces without developing leaks. This allows a pipe that has already been installed to be realigned after installation (up until the pressure test) Material High performance synthetic PPSU stainless steel press sleeve Uponor modular MLC fitting-system for risers and distribution-pipes 63 – 110 mm Description/characteristics The MLC modular fitting system consists of a range of matching basic bodies and pressing adapters. Firmly fixed press sleeve, permanently connected with the fitting body protects against mechanical damage to the O-ring Press sleeves with inspection windows, the penetration depth of the pipe into the fitting can be checked before pressing In a second step, the ready-mounted press adapter is inserted, at the building site, into the basic body, and fixed with the lock pin to provide a secure connection. Material Brass, tinned Stainless steel press sleeve Uponor MLC compression fittings 14 – 25 mm Description/characteristics The Uponor MLC compression fitting can be used for the direct connection of the Uponor Unipipe MLC pipes to ½“ Uponor fittings, manifolds, and plumbing press fittings. The ¾“ variation permits the connection to ¾“ Eurokonus fittings. T E C H N I C A L M A N U A L M LC P S Y S T E M 0 8 / 2 0 0 9 Material Coated brass union nut insert part PPSU polyamide (PA) press ring 9 The first colour coding system in plumbing – fast, exact and secure installation Fast and secure installation Practical experience implemented in installation Colour coded stop rings on the well-known and quick to install metal press fittings mark Uponor’s latest fitting generation. Each dimension from 14 to 32 mm has its own colour – ensuring simplicity onsite, in warehouse and wholesale. The colour code system makes installation a mere child’s play and reliably prevents any kind of mixup. The foundation of the system continues to be the proved and tested Uponor metal press fitting in the latest generation now with colour coding. The new coloured stop rings offer a safe stop for the pressing jaws. During the pressing procedure they automatically fall off and thus mark the pressed connection; nonpressed connections catch the eye even in a few meters distance when doing visual controls. Coloured stop rings 10 On account of the unobstructed design insulation can be pushed effortlessly over the pressed connections. The innovative optical press marking ensures secure and fast onsite installation. Benefits Colour coding of fittings and pressing jaws for fast and safe allocation of each dimension from 14 – 32 mm DVGW- approval also with new pressing jaw Reliable optical press marking by falling off of the coloured stop ring – fast and costefficient installation Unobstructed pipe conduit facilitates subsequent insulation 100 % compatible to existing Uponor MLC pipe systems Slim and appealing on-wall installation Pressing indicators on the pressing jaw T E C H N I C A L M A N U A L M LC P S Y S T E M 0 8 / 2 0 0 9 New: Secure and fast connection with integrated check 1. Placing Place the pressing jaw at the stop ring of the press sleeve. 2. Pressing When pressing the stop ring falls apart and off the press sleeve. 3. Testing The separated stop rings mark a successful pressing – reliable detection even from a few meters distance. 4. Insulating A continuous pipe insulation like Tubolit can be pushed effortlessly over the unobstructed connection. If a connection has not been pressed yet, it catches the eye twice during the hydraulic pressure test. The coloured stop rings are still there, and additionally the fitting is designed to leak water during the water pressure test. Now simply press and the connection is sealed permanently. T E C H N I C A L M A N U A L M LC P S Y S T E M 0 8 / 2 0 0 9 11 Robust, solid, reliable - the Metall press fitting with outstanding properties The new Metall press fitting generation from Uponor is the result of continuous further development and optimization, based on both theoretical considerations and practical experience. Thanks to the new stop ring, the Metall press fitting from Uponor is now even more user-friendly. On the one hand it ensures that the pressing jaw acts at the correct position during pressing, while on the other hand it fixes the stainless steel pressing sleeve to the fitting body. So nothing can get lost, and both the O-rings on the supporting sleeves and the supporting sleeves themselves are protected from damage and soiling. The proven inspection windows in the pressing sleeve, which permit visual checks of the penetration depth, also contribute to maximally secure processing. Benefits Use of high quality materials Pressing sleeves are fixed to the basic body Stop ring for optimum pressing jaw action Inspection window for checking the pipe penetration depth Safe and easy to install – Uponor MLC composite press fittings with new features The classic with improved properties. The next generation of Uponor composite fittings for drinking water installations and for the connection of radiators, with sizes from 16 - 32 mm, is available right now. The familiar ease of assembly, and the test safety offered by the "not pressed, not sealed" feature, are valued properties of Uponor Plus on the building site. The visual characteristic that identifies the new generation is the white plastic stopper-ring on the preassembled, stainless steel sleeve. 12 Benefits new fitting generation with white stop-ring with stainless steel press sleeve (fixed) lightweight, stable PPSU body fast and economical installation for tap water and heating reliable testing T E C H N I C A L M A N U A L M LC P S Y S T E M 0 8 / 2 0 0 9 The new, modular Uponor MLC fitting system for distributor pipes and rising mains: flexible planning, reliable procurement, easy assembly Faster planning with only 27 components Flexible for planning changes Conventional 63-110 mm installation systems need up to 300 different components. The Uponor MLC fitting system for distributor pipes and risers mains needs just 27 components - a significant aid to planning. In spite of the easily managed number of components, the system copes with practically any imaginable task, and opens up room for creative solutions. When unexpected problems that call for modifications to the plans are met on the building site, the fitting-and-lock principle of the connecting technology allows you to react flexibly. Connections can be unlocked, released and put back together again until pressure test is done. Benefits Only 27 system components allow for hundreds of variations. New connection method, consisting of a basic body and matching adapter inserts of tin plated. Innovative push-in connection between basic body and adapter. Greater flexibility and lower logistics costs through the minimum number of system components. Optimum availability together with low needs for warehouse space and for investment. Fast assembly through pressing at the Workbench and pushing together on site without tools. Use of the familiar UP 75 pressing tool now up to dimensions of 110 mm Simple correction options when plans are modified during installation nent available at all times. Fewer components also implies a lower required investment, less administration, and a smaller space required in the warehouse. In addition, there are no rarely needed special components - if a component is left over at the end of a project, it can easily be used for the next project . Building delays caused by long delivery times, such as are only too common with special fittings, therefore become a thing of the past.

First cut the Uponor MLC pipe in length Take advantage of this unique innovation! Concise product line – high functionality We have concentrated our compression fitting range and made it more user-friendly, at the same time keeping its high functionality in mind! For example now all 1 inch formed items and compression adapters have been changed to selected ¾ inch eurocone items. This means for you: less storing and no hazard to mix-up! The new compression fitting with eurocone replaces many parts of the previous Uponor compression adapters and has been supplemented with a plastic insert made of PPSU which is in contact with the medium water. That will substantially decrease metallic influences. 2. Mark the plug-in depth on the pipe via assembly aid (enclosed in all fitting boxes) 3. Insert the pipe in the new Uponor compression fitting (the inner part has already been firmly connected factory-made!) 4. Tighten to the stop by using a wrench. For ½ and ¾ inch connections until the torque noticeably increases and the mark becomes visible Easy installation Best-of-all: As the torque has been reduced by approx. 50%, processing has become considerably easier and faster. A torque wrench is no longer required, simply use a wrench until the mark becomes visible. Assembly times are therefore considerably reduced. T E C H N I C A L M A N U A L M LC P S Y S T E M 0 8 / 2 0 0 9 5. Done 15 Equipotential bonding DIN IEC 60364 ff. requires equipotential bonding between all types of protective conductors and the “conductive” water, waste water and heating pipes. Since an Uponor Unipipe MLC pipe is a non-conductive pipe it cannot be used for equipotential bonding and is not to be grounded. Equipotential bonding is affected according to the VDE guideline from the parts that are to be earthed directly to the equipotential bus bar at the point provided in the plan. The installer or construction supervisor has to point out to the client or their agent that a certified electrician must check whether or not the Uponor installation impairs the existing electrical protection and grounding measures (VOB part C, General technical specifications for building works ATV). Mixed installations For tap water installations with two or more metal pipe systems, as seen from the flow direction, first the base metal and then the high-grade material must be used, i.e. first the galvanized steel pipe then the copper pipe. Since the beginning of 1997 the white Uponor Unipipe MLC pipe (PERT/AL/PE-RT) has been delivered for all applications (tap water, heating and radiant heating installation). The Uponor MLCP system can be combined with metal and plastic pipe systems. As opposed to mixed installations using different metals, with the Uponor system it is not necessary to adhere to a tap water flow direction. If older Uponor Unipipe MLC pipes are to be extended or repaired, the Uponor MLC press repair coupling offers the possibility of changing to the current Uponor Unipipe MLC pipe. The repair coupling is available in the dimensions 25, 32 and 40. The inner insert part extended on one side of the coupling also simplifies joining of the pipe ends to lack of space. Repair or renovation work In the past different variations of the Uponor Unipipe MLC pipe were delivered. Red Unipipe F composite pipe (PE-MD/AL/PE-MD) for underfloor heating installation Brown Unipipe S composite pipe (PE-X/AL/PE-X) for tap water installation White Unipipe H composite pipe (PE-X/AL/PE-X) for heating installation Existing installation Tap water Unipipe S (PE-X/AL/PE-X) By renovation, extension or repair: Unipipe H (PE-X/AL/PE-X) Unipipe E (PE-RT/AL/PE-RT) 16 Tap water installation, Heating system installation Uponor Unipipe MLC (PE-RT/AL/PE-RT) Heating system Tap water, heating, Under-floor heating, wall heating Standard fittings with a stainless steel press sleeve can be used with pipe fittings starting from dimension 40 mm. New installation (from 1997) Under-floor heating Unipipe F (PE-MD/AL/PE-MD) Moreover with the smaller dimensions up to 32 mm the transition of existing to new installations is also possible using the composite press couplings or up to dimension 25 with screw connections in combination with double nipples. Example: Transition with Uponor MLC press repair coupling T E C H N I C A L M A N U A L M LC P S Y S T E M 0 8 / 2 0 0 9 Outer corrosion protection of Uponor fittings Because of the external corrosion protection there are no restrictions for mixed installation with other installation systems. The generally accepted rules of technology are to be complied with. In view of the surface corrosion protection, Uponor MLC fittings can be installed directly in concrete, screed or under plaster. However, there are some circumstances where protection from metallic connections or metallic components that come into direct contact with building materials is required, these are the combination of: permanent or long-lasting moisture penetration and a pH value greater than 12.5. In this situation we recommend a suitable covering for the Uponor MLC fittings such as insulating tape or shrink sleeve. Independent of the corrosion protection of the mouldings, all legal requirements and relevant standards for the respective application, particularly from the stand-point of thermal insulation and sound decoupling, must be adhered to. Before applying the insulation the prescribed pressure test is to be run. Threaded connection handling instructions The thread sealants must have been tested and approved for the respective application. The sealants must be used according to their manufacturer‘s instructions. Uponor MLC press fittings may only be coupled with standard screw threads (DIN EN 10226). The threaded connection must be made before pressing so that no stress is placed on the press fitting connection. The threaded connections must be made properly in accordance with the generally accepted rules of technology. No undo force may be used when working with brass components. Excessive thread sealant (e.g. excessive hemp packing) at the threaded connections must be avoided. T E C H N I C A L M A N U A L M LC P S Y S T E M 0 8 / 2 0 0 9 The following points must be observed when making threaded connections: Excessive tightening of the threaded connection can result in damage to the material; suitable tools must be used. The installation tools may not be lengthened to increase the force when tightening a connection (e.g. by attaching pipes), All the materials and auxiliary materials used (e.g. sealants, installation material and cleaners) must be free of substances that can cause stress corrosion cracking (e.g. compounds containing ammonia or chloride). Caution! For tap water installations, sealants must be authorized and certified by the DVGW (DVGW seal). 17 Installation time calculations for the Uponor MLCP system General The function of the calculation is the costing of construction works and the generation of an offer. Thereby a tender specification is produced in which the construction work required is described in detail. The general conditions for the calculation are specified in the current VOB (General technical regulations) part C DIN18380: "VOB assignment and contract policy for for building works and supplies - part C: Heating systems and central water heating installations" and DIN 18381: "VOB assignment and contract policy for for building works and supplies - part C: Gas, water amd sewage plumbing works inside of buildings" Installation times contain the following work: Preparation of tools and supplementary equipment at the building site 18 Reading the plans Pipe run calibration Pipe measurement, marking, cutting to length, bevelling and cleaning Pipe installation, including fastening Pressing The following supplementary services are not covered in the installation time: Producing assembly schedules Setting-up and clearing the building site Day wages Insulation work Pressure test Construction control To prepare a bill of quantities The supplementary services specified above should be listed separately in the tender. The following specified installation times are based on the practical experiences of Uponor users. Furthermore the calculation methods in Germany differ greatly from state to state or within different regions. Due to this the following compiled installation times can represent only an approximate costing basis. You can get more accurate statistics from the responsible trade associations, which have access to extensive data. Before use all specifications are to be checked for correctness by the responsible engineer/plumber. Uponor does not take liability for the correctness of the specifications or for any possible consequential damages, which arose or can arise due to incorrect guidelines, except for gross negligence or if deliberately wrong data were supplied by Uponor or their agents.

Certificates According to DVGW worksheet W 542 a minimum useful life of 50 years must be proven for multilayer composite pipes used in tap water distribution systems. For this purpose an independent testing institute runs a series of tests in order to produce an internal pressure creep rupture diagram. For Uponor this report was produced by the South German Plastics Centre in Wurzburg (SKZ). Along with other tests, the internal pressure creep rupture diagram forms the basis for 24 DVGW issuing a mark of approval for Uponor with all associated connectors. Together with the test institute and DVGW, Uponor works continuously on the testing of the pipe system in accordance with all relevant DVGW worksheets. DVGW certification permits the use of the Uponor MLCP systems in tap water installations in accordance with the requirements of DIN 1988 TRWI (Technical regulations for drinking-water installations) All components coming into contact with tap water are materials and articles in the sense of the German Foodstuff and Consumer Goods Act. The Uponor MLCP system corresponds to the recommendations of the German Federal Board of Health (KTW recommendation), and through the DVGW mark of approval is also accordingly reviewed and recognized. The brass alloy used for the Uponor MLC fittings corresponds to DIN 50930-6 and fulfils the requirements of the German tap water directive (TrinkwV). For use world-wide, Uponor has more than 60 international certificates (e.g. ÖVGW, SVGW, KIWA, CSTB, etc.).

Legionella is rod-shaped bacteria, which naturally occur at low concentrations in fresh water e.g. lakes, rivers and occasionally also in tap water. Approximately 40 forms of the legionella bacteria are known. Some legionella forms can cause infections through the inhalation of contaminated aerosols (fine water droplets) e.g. while showering or through moisturizers in air-conditioners. For people with health problems e.g. weakened immune system, chronic bronchitis etc. this can lead to pneumonia (legionella pneumonia or legionnaire‘s disease) or to Pontiac fever. According to DVGW worksheet W 551 the infection risk is a direct function of the temperature of the water from the tap water installation. The temperature range in which increased the legionella growth appears is appropriate between 30 °C and 45 °C. Based on the present level of knowledge, the workpaper describes the necessary technical measures for the reduction of legionella growth in tap water installations. Additional measures are described for the rehabilitation of contaminated tap water systems. Circulation systems Warm water distribution systems in which warm tap water is constantly available at the taps must maintained permanent hot water circulation. For the operation of circulation systems, the conditions as stipulated in DVGW worksheets W 551 and W 553 must be maintained in order to avoided the above mentioned health risks. the other hand a sufficient warm water volume flow must be present in all circulation lines. The DVGW worksheet recommends the operation of a circulation system with a water temperature of at least 57 °C at the end of each return line. The required flow rates are calculated in accordance with DVGW worksheet W 553. Requirements This worksheet contains three calculation procedures: The complete warm water distribution system is to be operated in such a way that on the one hand the warm water leaves the tap water heater with at least 60 °C and returns to the heater with a temperature loss of no more than 5 K. On 26 A short procedure for small systems (e.g. one and two family houses), with which no calculations must be made. A simplified procedure for all system sizes with the goal of supplying a calculation method which supplies sufficiently accurate results for the draft and the implementation without excessive effort. A differentiated procedure for all system sizes with the goal of achieving a better approximation of the real operational conditions, particularly for large systems. The mentioned calculation methods should be taken from the DVGW worksheet W 553. The Uponor HSE calculation software is available for these calculations. T E C H N I C A L M A N U A L M LC P S Y S T E M 0 8 / 2 0 0 9 Uponor „Aquastrom T plus“ Thermostat preset for circulation conduit Uponor “Aquastrom T plus” is a preset thermostat for circulation conduit that conforms to DVGW worksheets W551 and W553. It regulates the circulation water temperature in the recommended range of 55 °C to 60 °C (max. control range 40 °C to 65 °C; accuracy +/- 1 °C). The valve automatically supports thermal disinfection. The volume flow rises approximately 6K above the set temperature and reduces itself, independent of the temperature set, starting from approximately 73 °C on the remaining volume flow. The valve thereby optimally supports the thermal disinfection of the circulation system. The maximum volume flow can be preset and locked, independent of the temperature set. The valve is made from red brass and is equipped with a drain valve with a hose mounting that allows the circulation branch line to be emptied for maintenance purposes. Temperature monitoring is possible with thermometers or temperature sensors. The temperature setting is protected against change by a seal cover. The temperature value set can still be read. Max. operating temperature: 90 °C Nominal pressure: 16 bar Factory settings: Temperature: 57 °C Volume flow setting: DN 15: 2.0 DVGW certified Benefits Automatic thermal regulation of the volume flow Supports thermal disinfection Volume flow rises approx. 6 K above the temperature set, thus quickly reaching the disinfection temperature in the branch line Restricted above 73 °C, the volume flow is again normalized in order to ensure disinfection of additional components High corrosion resistance Temperature setting can also be read with a seal cover installed Later sealing is possible Temperature monitoring with thermometer or temperature sensor (accessories) is possible for the incorporation in building control technology The maximum volume flow can be preset and locked independent of the set temperature and can be shut off for maintenance. Integrated drain valve with hose connection Use of trace heating The Uponor Unipipe MLC pipe is suitable for use with trace heating. The inner aluminium pipe ensures uniform heat distribution around the pipe, the customary temperature limitation of 60 °C by the manufacturer is to be respected. The fixing of the heating band is to be done according to the manufacturer’s instructions, whereby the Uponor Unipipe MLC pipe is to be classified as a plastic pipe. You must make sure that the water can expand correspondingly if Uponor Unipipe MLC pipes with a self-regulating heating band are permitted. If this is not the case, e.g. as with tank outlets to the warm water distributor, short lines to the usage points or with house connection lines that only bypass one story, damage of the Uponor of pipe due to the high increase in pressure cannot be ruled out. T E C H N I C A L M A N U A L M LC P S Y S T E M 0 8 / 2 0 0 9 For these cases suitable safeguards are to be taken, e.g. the installation of a suitable safety valve or expansion vessel. Note: The pressure increase of the components due to the use of heating tape is to be closely watched. Suitable safety precautions are to be planned that ensure pressure equalization. The manufacturer’s assembly guidelines and installation notes for the self-regulating heating band must be observed. 27 Connection to instantaneous water heaters, hot water tanks and mixer Connection to a instantaneous water heater using electronically controlled equipment to heat tap water. Due to their construction, hydraulically controlled, electrical and gas fired flow heaters can build up high temperatures and pressures, both in normal operation and as a result of a failure, which can cause damage to the pipe system. The Uponor MLCP system may only be directly connected to electronically controlled equipment. The manufacturer’s instructions must be observed when Connection to a hot water tank Generally it must be ensured when connecting hot water tanks (particularly with direct fired hot water tanks, solar storage tanks and special constructions) that in normal operation as well as in the case of a failure, the operation limits of the Uponor Unipipe MLC pipe are not exceeded. This applies in particular to the maximum warm water outlet temperature, which is to be checked at start-up or be obtained from the manufacturer. In the case of doubt, suitable safety precautions are to be taken (e.g. installation of an industrial water mixing valve). Mixer connections Fitting connection installation must be torsion-proof (e.g. by fixing the press tap elbow on mounting brackets or mounting plates). Humidity protection The humidity protection required in sanitary facilities is regulated by DIN 18195-5 “Water-proofing against non-pressing water”. The following implementations are limited to humidity protection within the area of sanitary fittings and wall bushings, e.g. within the area of dry lining panelling. 1 Dry area 2 Wet area Wall bushing seal with flexible silicone 2 Each sanitary facility can be divided in two “humidity classes”: 1 Wall bushing seal with stationary seal ring and integration into the surface seal 2 Humidity protection in the area of sanitary fittings and wall penetration With concealed fittings, a seal must be made to the brick-work or the opposite dry lining panelling with a suitable humidity seal. The tiler integrates these in accordance with the generally accepted rules of technology into a surface seal. The same applies to wall bushings for 28 equipment connections with surface mounted fittings, e.g. showers and bath tubs. Due to moisture build-up (condensation), particular at the cut-out sites in dry lining panelling, e.g. for urinal controls, a seal against mois- ture penetration must be applied to building material surfaces. All other wall penetrations within the dry area (e.g. against the ceramic facings/tiles) can be sealed with neutrally hardening sanitary silicone.

Before the pressure test, all components of the installation must be freely accessible and visible in order to be able to locate unpressed or incorrectly pressed fittings. All open pipes are to be closed with Uponor pressure test plug MLC or metal screw plugs, caps, blanking plates or blind flanges. Equipment, pressurized tanks or tap water heaters are to be separated from the pipes. It is recommended to perform the pressure test with compressed air or an inert gas if the pipe system is to remain unfilled after the test. At the final inspection the pressure test and flushing must be done with water in accordance with DIN 1988-2. Pressure test with compressed air or inert gas The pressure test with compressed air or inert gas is to be run in accordance with the generally accepted rules of technology in two steps, the leak test and the strength test. With both tests, before starting the test period, you must wait for temperature equalisation and steady-state condition after pressure build-up. Leak test A visual inspection of all pipe connections is to be made before the leak test. The pressure gauge used for the test must have an accuracy of 0.1 bar in the display range for the pressure being measured. The system is pressurised with a test pressure of 110 mbar. For a system volume of up to 100 litres the test period must be at least 30 minutes. The required time is extended by a further 10 minutes for every additional 100 litres. During the test no leakage may appear at the connectors. Strength test The strength test is to be run following the leak test. Here the pressure is raised to a maximum of 3 bar (pipe dimension ≤ 63 x 6 mm) or a maximum of 1 bar (pipe dimensions ≥ 63 x 6 mm). For a system volume of up to 100 litres the test period must be at least 30 minutes. The required time is extended by a further 10 minutes for every additional 100 litres. elapse to allow for the temperature equalisation between the ambient temperature and the temperature of the fill water. If necessary, the test pressure must be re-established after the waiting period. After completion of the pressure test all fittings are to be checked for possible leakage. The results of the pressure test must be recorded in a report as a record for the plumber and customer. The forms at the end of this chapter can be used for this report. Pressure testing with water A visual inspection of all pipe connections is to be made before pressure testing with water. The pressure gauge must be connected at the lowest point of the installation being tested. Only measuring instruments may be used where a pressure difference of 0.1 bar can be read. The installation must be filled with filtered tap water (protect against frost!) and vented. Shut-off valves before and after boilers and tanks are to be closed so that the test pressure is kept away from the rest of the system. The system is to be pressurized with the maximum permissible operating pressure (10 bar) plus 5 bar (in relation to the lowest point of the system). Check the maximum operating pressure with pressure boosting systems! A suitable time must 30 Preliminary test Re-establish the test pressure two times within 30 minutes at intervals of 10 minutes. After a further 30 minutes the test pressure must not have dropped by more than 0.6 bar. Main test The main test is to be run directly following the preliminary test. The pressure test is considered to have been passed successfully if the test pressure has not dropped by more than 0.2 bar after a further two hours.

The procedure for the pipe line flushing is described in the ZVSHK brochure “Notes on flushing methods for tap water installations in accordance with TRWI 1988”. This brochure can be obtained from the German Central Association of Plumbing, Heating and Climate-Control System Engineers (ZVSHK), Rathausstrasse 6, 53757 St. Augustin. Details and general information on flushing with water can be taken from the brochure. Under point 4.1 the brochure states: “The pipes must be flushed as soon as possible after installation. The tap water used for the flushing must be filtered (filter in accordance with DIN EN 13443-1).” The total system is to be flushed thoroughly as soon as possible after installation of the pipes and following the pressure test. Filtered tap water (filter in accordance with DIN EN 13443-1) is to be used as flushing liquid. In order to ensure an unlimited operational reliability, flushing must remove all contamination and installation residue from the interior surfaces of the pipes and system components, established the quality of the tap water as well as inhibit corrosion damage and malfunctions of the fittings and components. In general two flushing methods can be used: Flushing with an air water mixture in accordance with DIN 1988-2 In order to protect sensitive fittings (e.g. solenoid valves, flushing valve, thermostats etc.) and equipment (e.g. tap water heater) against damage from flushed foreign matter adaptors should be initially installed in place of such components. Such components should only be installed after the system has been flushed. Built in fine-meshed sieves installed in front of fittings that cannot be removed or bypassed are to be cleaned after flushing. Aerators, nozzles, flow limiters, shower heads or shower handsets must be removed from the remaining installed fittings during flushing. This procedure be based on a pulsating flow of water and air and is described in detail in the “Tap water supply systems; materials, components, appliances, design and installation (DVGW code of practice)” DIN 1988-2 section 11.2. Suitable flushing equipment is to be used. This flushing procedure should be used if flushing with water is not expected to produce a sufficient flushing effect. Flushing with water If no other flushing method is contractually agreed upon or emanded, the Uponor tap water pipelines are The manufacturers’ installation instructions are to be followed for concealed thermostats and other sensitive fittings that cannot be removed during flushing. All maintenance fittings, floor shut-off valves and pre-shut-off valves (e.g. angle valves) must be fully opened. Possibly built-in pressure reducers must be fully opened and only be adjusted after flushing. Depending on the size of the system and the pipe routing, the installation can be flushed in sections. In this case the flushing direction and sequence should be from the main isolation valve in sections and branches (actual flush section) from the nearest to the furthest branch. One floor after the other is to be flush beginning at the ascending pipe end. Within the story and single supply lines at least as many usage points specified as a guideline in the following table for a section being flushed are to be fully opened one after the other for at least 5 minutes. This is to be repeated for each story. Within the story the usage points, beginning with the usage point furthest away from the ascending pipe are to be fully opened. After a flushing period of 5 minutes at the flushing point last opened the usage points are closed one after the other in reverse order. For the Uponor Unipipe MLC pipe the following guidelines for the minimum number of usage points which are to be opened in relation to the largest inside diameter of the distribution conduit must be observed: 32 x 3 Pipe dimensions OD x s [mm] of the distribution conduit in the actual section being flushed 40 x 4 50 x 4.5 63 x 6 75 x 7.5 90 x 8.5 110 x 10 Minimum number of usage points to be opened DN 15 4 6 12 18 28 2 T E C H N I C A L M A N U A L M LC P S Y S T E M 0 8 / 2 0 0 9 8 31 MASTER Pressure test with water for tap water pipes Note: The chapter “Pressure test of tap water installations” in the actual technical manual “MLCP system for tap water installation and radiator connection” is to be followed. Construction project: Stage: Person carrying out the test: Test pressure = max. permissible operating pressure + 5 bar ≤ 15 bar (related to the lowest point of the system) All tanks, equipment and fittings, e.g. safety valve and expansion tanks, which are not suitable for the pressure test, must be removed from the system during the test period. The system is filled with filtered water and completely vented. A visual inspection of the pipe joints must be made during the test. After the test pressure has been reached a suitable time must elapse to allow for temperature equalisation between the ambient temperature and the temperature of the fill water. If necessary, the test pressure must be re-established after the waiting period.

Double-pipe heating system with tee connection and cross fitting VL RL Beginning from the house connection line, the heating water distribution is made by a common ring loop. If the ring loop runs directly by the radiator, the radiator connection can be made with a press connection tee. The last radiator of the ring loop is connected by an Uponor press angle bracket. If the radiator is connected over a single inlet to the ring loop, the use of a cross fitting is recommended. Installation possibilities – Single-pipe heating system VL RL With a single-pipe heating system all radiators of a heating circuit are connected to a closed ring loop. In this case ring loops are connected directly by a T-piece to the house connection lines of the heat generator. If there are several ring loops, these can be connected to the Uponor heater distributor. The distributor is in turn connected to the house connection line of the heat generator. As a rule, the adjustment of singlepipe heating systems is usually complex. With a single-pipe heating sys- tem the temperature gradient between the radiators, i.e. the decreasing supply temperature from radiator to radiator, must be consid- ered when dimensioning the heating element in the form of an area surcharge. Benefits are a result of lower material and assembly costs. return for each radiator is approximate equal. That means that the radiator with the longest supply has the shortest return. Thus a more uniform pressure drop in the individual stages is achieved.

Water heaters are to be checked with a pressure of 1.3 x the total pressure (static pressure) of the system; however, at least 1 bar excess pressure must be reached throughout the system. Only pressure meters may be used that permit the accurate reading of a 0.1 bar pressure change. The pressure meter is to be connected, if possible, to the lowest point of the system. The heating system is to be filled slowly and completely vented (protect against frost!). This can be done quickly and with little effort After the test pressure has been reached a suitable time must elapse to allow for temperature equalisation between the ambient tempera- The following procedure describes the pressure test for the Uponor MLCP system with screw or press connections. 46 ture and the temperature of the fill water. If necessary, the test pressure must be re-established after the waiting period. The test pressure must be maintained for 2 hours and may not drop by more than 0.2 bar. No leakages may appear during this time. As soon as possible after the cold water pressure test the system is heated to the highest calculated heating water temperature to check whether the system also remains leak-free at high temperature. After the system cools down the heating pipes and connections are to be checked for leaks.

rate (volume flow) of the particular stage. Depending upon the dimension of the pipe’s OD x s, the flow rate v and the pipe friction resistance R change. If the pipe selected is too small, the flow rate v and the pipe friction resistance R rise. This leads to higher flow noises and to higher current usage of the circulation pump. During the design of the pipeline we recommend that you not to exceed the following approximate velocity values: Radiator connection pipe: ≤ 0.3 m/s Radiator distribution pipe: ≤ 0.5 m/s Heating system house connection and cellar pipes: ≤ 1.0 m/s The pipe network has to be planned in such a way that the flow rate decreases uniformly from the boiler to the furthest radiator. The guidelines for the flow rate are to be observed. The maximum transferable thermal output QN is to be entered in the following tables under consideration of the maximum flow rate, in relationship to the type of pipe, spread ΔT and the pipe dimension OD x s.

If a fire occurs, then the second goal of fire protection is to minimize damage. In the context of building legislation the State establishes the preconditions in order to ensure public safety and prevent danger from destructive fires. The model building code (MBO) is the basis for all building regulations, including fire protection measures. The building codes of the individual German States are oriented on this model building code. According to MOB 2002 section 14 “Fire protection” (wording and contents also apply in the individual German States) pipes that pass through firewalls and stairwells, as well as walls and ceilings that must meet fire resistance grading, may only be installed if spreading of fire 56 or smoke is not a risk or if provisions have been taken against such possibilities. For example, when installing Uponor Unipipe MLC pipes (building material class B2 in accordance with DIN 4102) with an outside diameter OD ≤ 32 mm spreading of fire and smoke is not a risk if the area between pipe and the remaining cross-section of the opening is completely filled in with non-combustible, shape-retaining building material (closing the cut-outs with mortar and concrete). If mineral fibres are used, they must have a melting point of more than 1000 °C. In residential buildings the following basic fire protection principles apply: Along with the fire protection requirements, sound and thermal protection requirements as well as the thermal expansion/con- traction of pipe systems must be considered when installing pipes through openings in walls or ceilings. Fires and smoke may not spread into other ventilation zones within the required fire resistance grading (e.g. F 90 = 90 minutes). All building materials must fulfil the building material class B2 = normal inflammable. The high requirements of a fire prevention concept that guarantees health and life can only be realized with the cooperation of all parties taking part in the building project and with a tender and a construction supervision that is matched to the project. Uponor offers comprehensive fire prevention solutions for the composite pipe system. T E C H N I C A L M A N U A L M LC P S Y S T E M 0 8 / 2 0 0 9 Sound protection DIN 4109 with the supplementation table A1 determines the minimum sound insulation required in buildings for different needs as well as with reference to the noise source. The following maximum sound pressure levels in dB (A) are permissible: Excerpt from DIN 4109 with supplementation table A1: Source of noise Water installations (Water supply and waste water systems together) other equipment and appliances 1) 2) 3) Type of areas in need of protection: Living and sleeping areas Characteristic sound pressure level dB (A) Instruction and work areas Characteristic sound pressure level dB (A ≤ 30 1) 2) ≤ 35 1) 2) ≤ 30 3) ≤ 35 3) Single, brief peaks, which occur during actuating the fittings and equipment in accordance with table 6 (opening, closing, rearranging, interrupting etc.), are not to be considered at present. Contractual conditions for the fulfilment of permissible sound pressure levels of the installation:: - The final planning documents must consider the sound insulation requirements, which means, among other things, that the components must have the required sound insulation certifications. - Furthermore the responsible chief engineer must be designated and consulted for a partial acceptance before closing or covering the installation The ZVSHK instruction leaflet “Sound insulation” provides more information and can be obtained from the “German Central Association of Plumbing, Heating and Climate-Control System Engineers (ZVSHK), Rathausallee 6, 53757 Sankt Augustin”. Higher values of around 5 dB (A) are permissible with ventilation equipment, as long as it relates to continuous noise levels without any noticeable single tones. Under “other equipment and appliances” is understood to mean, for example, heating systems including heat distribution. Note: At present the maximum installation noise level LIN ≤ 30 dB (A) in house construction corresponds to the generally accepted rules of technology and actual case law. The purpose of all sound proofing measures is it to protect people in common rooms against unreasonable harassment by sound transmission. The following are to be understood as areas that need protection in accordance with to DIN 4109 with supplementation table A1: Living space, including halls Sleeping areas, including overnight accommodations in pensions and bed areas in hospitals and sanatoriums Classrooms in schools, universities and similar facilities Office space (excluded open-plan offices), consulting rooms, meeting areas and similar work areas B A B A Example: The area in need of protection in dwelling A is to be protected against the noise of the “sound from area B” and the other way around. Wall and ceiling weights are given pursuant to DIN 4109 Deviations are only possible with a sound related proof of suitability Dwelling ceiling partition m’ > 410 kg/m2 Single-shell installation wall within a personal living area m’ > 220 kg/m2 T E C H N I C A L M A N U A L M LC P S Y S T E M 0 8 / 2 0 0 9 57 Sound insulation in accordance with VDI 4100 In addition to the requirements of DIN 4109 an increased sound insulation can be contractually agreed upon in accordance with VDI 4100. This contains similar sound insulation levels as in DIN 4109 – however with other sub-sections. In this VDI guideline are also useful tips for practical sound insulation planning. Apart from their function as limits for construction acoustics, the sound insulation levels specified above are also of importance as acoustic quality characteristics for sanitary products. A product that meets the sound insulation levels of SSt II or SSt III ensures a high measure of noise reduction and an additional safety margin for use in the construction of living and sleeping areas as well as for instruction and work areas. The VDI 4100 specifications are as follows: Sound insulation level I is no longer state of the art and is therefore irrelevant Sound insulation level II corresponds to the minimum DIN 4109 requirement of LIn < 30 dB (A) With LIn < 25 dB (A) sound insulation level III ensures an increased acoustic comfort 58 However, if VDI 4100 should be agreed upon in the construction of double and terraced houses, then the basic values must all be reduced by 5 dB (A). If VDI 4100 is contractually specified, sound insulation requirements of maximum 30 dB (A) within personal living areas must be maintained! If waste water noises are regarded separately, then the basic values must be reduced by 5 dB (A). This means that all installations within personal living areas must be accurately coordinated with one another and that all doors must also accommodate these conditions. The specifications represented here refer to common rooms in the sense of state building codes, which makes the specifications more comprehensive than the areas needing protection pursuant to DIN 4109. insulation with/without fire protection Sufficient dimensioning of the Uponor Unipipe MLC pipes Inserting a sound damming inset, e.g. rubber on the securing clips for pipes as well as on equipment and fixtures Covering of the Uponor Unipipe MLC pipes with soft elastic insulating materials when installing pipes in walls or ceilings, e.g. the normal insulation Uponor press MLC wall plates with sound protection set Structure-borne sound transmission can be effectively prevented in tap and waste water systems by the following measures: Covering of the Uponor Unipipe MLC pipes with soft elastic insulating materials when installing pipes through openings in walls or ceilings, e.g. the normal thermal Sound protection in accordance with DIN 4109 tested by the Fraunhofer Institute for building physics (IBP), Test report P-BA 242/2004 T E C H N I C A L M A N U A L M LC P S Y S T E M 0 8 / 2 0 0 9 Thermal protection Building insulation helps to minimize the energy consumption and lower the accompanying waste gas quantity as well as the fuel and power costs. In particular, high potentials savings can be realized in building equipment for energy production and distribution. The German Energy Saving Directive (EnEV) demands the limitation of the heat emission of heat distribution and warm water pipes. water pipes as well as fittings in buildings. Insulation requirements pursuant to EnEV Heating pipes and their fittings are to be insulated pursuant to lines 1 to 7, warm water pipes and fittings pursuant to lines 1 to 5 from table 1, appendix 5, of the EnEV.

This also applies to warm water pipes in dwellings where the pipes have an inside diameter up to 22 mm, which are not used in the circulation flow or with electrical companion heating.

With the use of insulating materials with a heat conductivity other than λ = 0.035 w (m x K) the insulating layer thicknesses are to be recalculated. The conversion is to be done using computing methods and nominal values provided by the generally accepted rules of technology. 59 In the following tables the minimum insulation layer thicknesses with various thermal conductivity λ are supplied for the Uponor Unipipe MLC pipe.

These pipes enable a time saving installation as the time intensive insulation and the gluing together of joints on the building site is not necessary.

Through exact clarification of the pipe routing and coordination with the architect, planner and chief engineer in advance of the actual installation, large sections of the system can be preassembled for cost-effective installation. The basis for the Z-dimension method is a uniform measuring method. All the lines to be installed are measured over the axial line by measuring from centre to centre (intersection of the axial lines). (Example: LR = LG - Z1 - Z2) With the help of the Z-dimensions of the Uponor press fittings, the plumber can quickly and easily calculate the exact length of pipe T E C H N I C A L M A N U A L M LC P S Y S T E M 0 8 / 2 0 0 9 71 Bending Uponor Unipipe MLC pipes The Uponor Unipipe MLC pipes 14 x 2.0; 16 x 2.0; 18 x 2.0; 20 × 2.25; 25 × 2.5 and 32 × 3 mm can be formed by hand with a blending spring or bending tool. The minimum bending radii may not be less than those specified in the following table. If a Uponor Unipipe MLC pipe is inadvertently broken or otherwise damaged it is to be immediately Attention: Hot bending of Uponor Unipipe MLC pipes over an open flame (e.g. soldering flame), or other heat sources (e.g. heat gun, industrial dryer) is prohibited! Do not bend more than once at the same point! replaced or a Uponor press or compression coupling is to be installed. Note: In this context make certain that the bending radius (e.g. in the area between floor and wall) does not fall below the minimum radius. If the minimum bending radius is not reached, a suitable fitting (e. g. a 90° press elbow) must be used.

Temperature difference ΔT and the pipe length L play a decisive role in the length variation. For all installation variations the heat expansion of Uponor Unipipe MLC pipes must be considered in order to avoid excessive stress in the pipe material and damage to the connections, in particular by free laid pipes such as radiator connecting pipes out of the floor or from the baseboard as well as with cellar distribution and house connection lines. For pipes that are laid in the wall under plaster or in the screed, the heat expansion is compensated for by the insulation in the area of direction change. The following equation is used to calculate the length variation: Δl = a × L × ΔT Here: Δl Heat expansion (mm) a Linear expansion coefficient (0.025 mm/(m × K) L Pipe length (m) ΔT Temperature difference (K) 90 ΔT = 70K 80 ΔT = 60K Δ l = Expansion [mm] 70 ΔT = 50K 60 ΔT = 40K 50 40 ΔT = 30K 30 ΔT = 20K 20 ΔT = 10K 10 0 0 20 10 40 30 50 Pipe length [m] Cellar distribution and house connection lines Uponor Unipipe MLC pipes may not be installed rigidly between two fixed points.

The dimensioning of the pipe supports is to be determined from the total mass (pipe weight + medium weight + insulation weight) in accordance with the generally accepted rules of technology. It is recommended to set the pipe supports, if possible, in the proximity of the fittings and connectors. Pipe installation onto the raw floor When installing pipes on a concrete floor the generally accepted rules of technology are to be observed. The sound insulation is to be installed in accordance with DIN 4109 “Sound protection in above ground construction”. The insulation regulations pursuant to the German Energy Saving Directive EnEV and in accordance with the Codes of practice for tap water installations (TRWI) DIN 1988-2 are to be observed.

If screeds are applied on insulating layers (floating screed), DIN 185602 “Floor screeds in building construction” is to be particularly followed. In DIN 18560-2: 2004-04 the following additional declarations are made (point 4.1 loadbearing substrate): “In order to accept the floating screed the load-bearing substrate must be sufficiently dry and have an even surface. The smoothness and tolerance must correspond to DIN 18202. It may not contain any peaks, pipes or anything similar that can lead to sound bridges or fluctuations in the screed thickness. Furthermore, for prefabricated heating floor screeds the special requirements of the manufacturer as to the smoothness of the load-bearing substrate are to be observed.

A smooth surface is to be created for the installation of the insulating layer – at least the sound insulation. The required construction height must be planned for. When installed, the levelling layer must exhibit a closed form. Fill may be used, if its serviceability is proven. Insulating materials may be used as a levelling layer. Sealing against ground moisture and non-accumulating seepage water are to be determined by the building planner and be prepared before installation of the screed (see DIN 18195-4 and DIN 18195-5)”. The routing of the Uponor Unipipe MLC pipes and other plumbing on concrete floors is to be done nonintersecting, straight and as axially parallel and parallel to the walls as possible. The preparation of a plan before the installation of the pipe tracks and other plumbing makes the installation easier. 75 Mounting distances during pipe installation on a concrete floor When installing Uponor Unipipe MLC pipes on concrete floors a fixing distance of 80 cm is recommended. The pipe is to be fixed within a distance of 30 cm in front and behind each bend. Pipe crossings are to be fixed. The fixing can be done using a synthetic plugged hook for single or double pipe fixing. When using a perforated tape for fastening, you must make sure that the Uponor Unipipe MLCP with/ without protective tube or insulation can freely move. Noise can be caused by the thermal expansion of the pipe if it is firmly fixed. If the Uponor MLC P system is installed directly in the screed, the pipe fittings must have suitable protected against corrosion. In order to prevent damage to the screed and floor covering, joints (expansion joints) are to be placed in the insulating layer and in the screed over construction joints. Uponor Unipipe MLC pipes, which cross construction joints, must be sheathed in the joint area at least with a longitudinally slit Uponor joint protection tube (20 cm each side of the expansion joint). 80 30 80 30 Pipe routing Pipes and other plumbing in the floor construction are to be planned without crossings. The routing of the pipes on concrete floors is to be done as non-intersecting, straight and as axially parallel and parallel to the walls as possible. The following route dimensions for pipes and other plumbing should be maintained: Field of application Width or spacing dimension Route width of parallel running pipes including pipe insulation Width of the footing beside a track (for the narrowest possible pipe-laying) Distances from wall to pipe/pipe route including insulation as footing for the screed in rooms, apart from corridors Distances from wall to pipe/pipe route including insulation as footing for the screed in corridors ≤ 300 mm ≥ 200 mm ≥ 500 mm ≥ 200 mm min. 200 mm Distance from wall to pipe/pipe routes including insulation and screed in rooms, apart from corridors min. 500 mm max. 300 mm min. 200 Screed Moisture barrier Sound insulation Distance from wall to pipe/pipe routes including insulation and screed in corridors 76 Levelling layer Bounded fill Concrete floor T E C H N I C A L M A N U A L M LC P S Y S T E M 0 8 / 2 0 0 9 Installation under mastic asphalt Mastic asphalt is brought into the room at a temperature of up to 260 °C. Therefore the Uponor Unipipe MLC pipe and all other temperature sensitive plastic components must be protected. The Uponor system edging strips can not be used with mastic asphalt. For this application there are special bitumen suited mineral fibre edging strips, which are to be procured by the customer. The Uponor MLCP system can be used without problems with mastic asphalt by observing following precautions. The un-insulated Uponor Unipipe MLC pipe must at least be placed in a protective tube. The use of preinsulated Uponor Unipipe MLC pipe is recommended in order to fulfil the requirements of DIN 1988 and the German Energy Saving Directive (EnEV). The Uponor MLCP system is to be filled with cold water and pressurized in order to be able to locate any possible damage caused by the laying of the mastic asphalt. Caution: Cold water must constantly circulate through the pipe in order to be able to find a any damage caused by the pouring of the mastic asphalt. The installation of mastic asphalt screed over Uponor Unipipe MLC pipes can be carried out by observing the following floor construction (from bottom to top): mastic asphalt-resistant edging strip mastic asphalt overlapped rib pasteboard or wool felt pasteboard mastic asphalt-resistant mineral plates levelling layer bounded fill concrete floor pre-insulated Uponor Unipipe MLC pipe Install the Uponor Unipipe MLC pipe in a protective tube or preinsulated Uponor Unipipe MLC pipe on top of the concrete floor Perlite fill as levelling layer to the upper edge of the protective tube or pipe insulation Mineral fibre mat at least 20 mm thick (mastic asphalt suited) WLG 040 Mastic asphalt, pouring temperature approx. 260 °C System components (pipes and fittings) that can come into contact with mastic asphalt (e.g. when installed under a radiator), are to be sheathed with 50% insulation (at least 20 mm thick) that is rated as fire protection classification A1 (non-combustible) pursuant to DIN 4102 (e.g. with mineral fibre insulation sheath RS 835/Conlit 150 P/U). The non-combustible insulation must fully enclose the Uponor Unipipe MLC pipe and the Uponor MLC fittings. The joints of the insulation sheaths and the transition points of the heat resistant thermal or sound insulation (mastic asphalt suited) to the non-combustible pipe insulation are to be taped with a temperature-resistant adhesive tape (e.g. Aluminium adhesive tape). The insulation sheaths around the pipe can also be alternatively fixed with binding wire. T E C H N I C A L M A N U A L M LC P S Y S T E M 0 8 / 2 0 0 9 These measures protect the Uponor MLC pipe system against radiant heat and against direct contact with the mastic asphalt. Pipe parts extending from the floor must be protected against direct contact with the mastic asphalt and/or the radiant heat. After hardening and cooling of the mastic asphalt the visible mineral fibres in the area of the Uponor Unipipe MLC pipe or the radiator connection are to be removed. The use of a floor rosette is recommended for a clean finish. Caution: The Uponor MLCP system must not come into contact with the mastic asphalt. The precautionary measures described are to ensure that the maximum temperature on the pipe surface does not exceed 95 °C! DIN 18560 “Floor screeds in building construction”, the specifications of the mastic asphalt manufacturer, the diligence and care of the mastic asphalt supplier, DIN 4109 “Sound protection in above ground construction” as well as the generally accepted rules of technology apply. 77 Transport, storage and installation conditions 78 General Operating temperatures The Uponor MLCP system is conceived in such a way that when installed as directed a maximum of system security is achieved. All system components are to be transported, stored and installed in such a way that a perfect functioning of the installation is ensured. The system components should be stored together grouped as to their functions in order to avoid confusing similar components with each other. In addition to the following notes, the directions in the respective fitting instructions of the individual system components and tools are to be observed. The permissible installing temperature for the Uponor MLCP system (pipes and fitting) is between -10 °C and +40 °C. The permissible temperature ranges for the pressing tools are to be taken from the respective operating instructions. Uponor Unipipe MLC pipe The Uponor Unipipe MLC pipes are to be protected against mechanical damage, contamination and direct sunlight (UV radiation) during transport, while stored and when being installed. Therefore, if possible, the pipes should be kept in the original packaging until installed. This also applies to unused components that are intended for later use. The pipe ends are to be plugged until used in order to prevent dirt entering the pipes. Damaged, buckled or distorted pipes may not be used. Pipe cartons with coils can be stacked up to a maximum height of 2 m. The pipe in straight length is to be transported and stored in such a way that it cannot bend. The relevant Uponor storage regulations are to be observed. Uponor Fittings Uponor MLC fittings may not be thrown or otherwise inappropriately handled. In order to avoid damage and contamination, the fittings should be kept in the original packaging until installed. Damaged fittings or fittings with damaged O-rings must not be installed. T E C H N I C A L M A N U A L M LC P S Y S T E M 0 8 / 2 0 0 9 Mounting instructions The installer must read and understand the instructions prior to mounting, and must observe them. When you receive the Uponor composite pipe system, you get proven quality. Please, nevertheless, check all the components for any possible transport damage before fitting. Observe the rules of good technical practice The applicable technical rules, DVGW worksheets, and German building regulations must all be observed in order to properly install the Uponor composite pipe system. The pipes must be laid in accordance with generally recognised codes of pratice. In addition, local rules, installation regulations, accident prevention regulations and safety specifications must all be observed.
