pansion valve (20), causing it to relax and subsequently absorb the heat from the cooling medium
(water-glycol mixture) in the evaporator coil.
The cooling medium is conveyed in a closed circuit
to the equipment via the pump (55) and cooling
medium tank (10). Temperature monitoring of the
evaporator coil (15) ensures protection against freezing if the flowrate is insufficient. The inlet temperature of the cooling medium (water-glycol mixture) is
regulated via the controller (80).
Flow diagrams for the individual unit types may be
found in chapter 13
General functional description
The primary purpose of Chillers is to supply a
cooled fluid (such as a water/glycol mixture) in order
to absorb heat at source and transport it away. The
fluid required for this purpose is supplied via a pipeline system.
In principle, the Chiller is comprised of four main
parts (cf. Figure 9 and 10):
- Evaporator coil (15),
- Refrigerant compressor (1),
- Condenser (5) with fans (10),
- Expansion valve (20),
which are connected to one another via pipelines.
The high-pressure switch (70) limits the maximum
pressure in the refrigerant cycle. The low-pressure
switch (71) switches off the refrigerant cycle in the
event of low pressure. Refrigerant R134a is free
from chlorine. Its ozone destruction potential (ODP)
is 0. A filter dryer (25) which is integrated into the
hermetically sealed cooling circuit provides effective
protection against moisture, acid, dirt particles, and
foreign bodies within the cooling circuit. The temperature control (80) ensures that the cooling medium
is kept at the preset temperature. In the evaporator
coil (15), the liquid refrigerant is transformed to a
gaseous state. The heat required for this purpose is
taken from the cooling medium in the plate heat
exchanger, thereby cooling it. The refrigerant is
compressed in the compressor (1), causing the
refrigerant to achieve a higher temperature level
than the ambient air. This heat is emitted to the
ambient air via the surface of the condenser (5),
causing the refrigerant to liquefy again. It is injected
into the evaporator coil (15) via a thermostatic exPage 8 of 104

Proper use
The Chiller was developed and designed in accordance with the latest state-of-the-art and the
recognised rules governing technical safety. Nevertheless, if used improperly, they may pose a threat
to life and limb or cause damage to property.
The Chillers described in this documentation are
intended solely for cooling water-glycol mixtures.
When using other fluids (such as deionised water),
please observe the technical specifications in the
Annex or contact the manufacturers. Under no circumstances should the tolerances specified in the
technical specifications be exceeded.

Cooling output [kW]
-
Filter mats (optionally available)
In case of coarse dust, lint and/or oily ambient air,
we recommend the use of an additional filter mat
(see chapter 11). Depending on the ambient conditions, the filters will need to be replaced at regular
intervals. By contrast, aluminium filter mats can be
cleaned using suitable detergents and then reused.

-
The Chiller also has a door contact switch to
prevent activation while the door is open.
Scope of supply
The unit is supplied in a packaging unit in a fully
assembled state. Check the supply contents for
completeness (see Table 3). Also, please check the
packaging carefully for signs of damage. For example, traces of oil on damaged packaging could
indicate a refrigerant leak.
Note:
Any damage to the packaging may be
the cause of subsequent malfunctions.

-
In order to make maintenance and repair work
easier, the minimum distances shown under Figure 21 should be adhered to.
-
In order to avoid an "air short-circuit" (mixing of
air intake and waste air) and ensure full cooling
output, the minimum distances shown under Figure 21 should be adhered to.
5.3
Minimum volume of installation site
The minimum volume of the installation site is calculated from the ratio of refrigerant fill volume [kg] to
the practical limit [kg/m³] of the refrigerant.
Note:
The practical limit (PL) is a refrigerantspecific value. It indicates the maximum permissible volume of refrigerant
per m³ of space which could be released suddenly without injury to persons.
Example:
A
The practical limit of refrigerant R410a is 0.44 kg/m³.
The refrigerant fill volume of Chiller 3335.790 is 2.3
kg. The minimum volume of the installation site [m³]
is therefore:

Siting the Chiller
-
Position the Chiller on a flat, stable surface.
-
Any deviations from the vertical must not
exceed a maximum of 2°.
-
A pressureless water tank is installed in the
Chiller. It must therefore be installed higher than
the equipment. For installation at a lower height
we recommend installing a non-return valve in
the inlet and a magnetic valve in the return of
the cooling medium circuit (optionally available)
so as to avoid a potential tank overflow (see Figure 22)
dium circuit before connecting to the Chiller.
A = Magnetic valve
B = Non-return valve
Fig. 22: Installation example with non-return and magnetic
valve
-
Installing an overflow valve (optionally available,
see chapter 11) ensures that cooling water circulation is always maintained with the magnetic
valves of the air/water heat exchangers closed
and the Chiller pump running. This is achieved
by opening the overflow valve as soon as the
static pressure exceeds the value set on the valve (see Figure 23).
Note:
To set the valve to the required pressure, please proceed as follows:
Remove the cap nut (1)
Loosen the lock nut (3) by twisting
in a counter-clockwise direction
and set the pressure screw (2) to
the required
Screwing it lower will increase the
pressure
Screwing it higher will reduce the
pressure
Next, tighten the lock nut (3) again
by twisting in a clockwise direction
The cooling medium outlet (see (10) Figure 5-8) of
the Chiller must be connected to the cooling medium inlet of the equipment. At the same time, the
cooling medium inlet (see (9) Figure 5-8) of the
Chiller must be connected to the cooling medium
outlet of the equipment. Please note the following:
To prevent condensation, always connect the
equipment using insulated pipelines and/or hoses.
The nominal width of the pipework should be at
least equivalent to the nominal width of the medium connections on the device.
The pipework must be suitable for the maximum
pressure (see chapter 15.4).
Note:
The use of steel pipes, zinc-plated steel
pipes and transparent hoses is not
permitted.
Before commissioning, the cooling medium pump
must be filled with cooling medium and vented (for
further details, refer to chapter 6).
Note:
With the water-cooled condenser (optionally available), make the cooling
water connections with the requisite
volumetric flow (as per the diagram in
the R+ID fluid plan).
Caution!
If the liquid to be cooled contains solid
particles, we recommend installation of
a mechanical filter upstream of the
cooling medium inlet. In order to ensure regular cleaning, two shut-off
valves should additionally be installed.
5.5
Danger!
It is vital to observe the following instructions.

Notes on electrical installation
When carrying out the electrical installation, it is
important to observe all valid national and regional regulations as well as the provisions of the
responsible power supply company. The electrical installation may only be performed by a qualified electrician who is responsible for compliance with the applicable standards and
regulations.

The connection voltage and frequency must
match the nominal values stated on the rating
plate.
No additional temperature control may be
connected upstream of the unit at the supply
end.
Set the pre-fuse (motor circuit-breaker) as per
the specifications on the rating plate.
The mains connection must ensure low-noise
potential equalisation. The device must be incorporated into the potential equalisation system of the building.
The cross-sections of the connection cable must
be consistent with the rated current (see rating
plate).
The unit does not have its own overvoltage protection. Measures must be taken by the operator at the supply end to ensure effective protection against lightning and overvoltage. The
mains voltage must not exceed a tolerance of
±10%.
In accordance with IEC 61 000-3-11, the unit is
intended solely for use at sites with a continuous current-carrying capacity (incoming
mains power supply) of more than 100 A per
phase and with a supply voltage of 400/230 V. If
necessary, the power supply company must be
consulted to ensure that the continuous currentcarrying capacity at the point of connection to
the public grid is sufficient for connection of
such a unit.
The connection must be made with a clockwise
phase sequence rotation. The direction of rotation can be measured from connection clamps
L1, L2 and L3. By connecting in a clockwise
phase sequence, you will ensure that all rotary
current motors have the correct direction of rotation.
Disconnect this connection and reassign it to 460 V (see Figure 24).
Fig. 24: Transformer connection
5.5.1 Connecting the voltage supply
The devices are wired ready for connection in the
factory, and equipped with a connection cable (3 m
long). Make the electrical connection as shown in
the circuit diagram (see wiring plan in chapter 15).
5.5.2 Retrieving a system message
You may additionally retrieve system messages
(warnings & alarms) via a floating contact on the
connection clamp of the Chiller. Suitable wires for
this purpose are already provided in the connection
cable (3, 4 and 5) and connected inside the device.
Note:
Connect the suitably labelled wires in
the connection cable to the controller
as shown in the electrical circuit diagram (see Figure 25).
Caution!
Electrical connection with 460 V / 60 Hz
If your machine uses an auxiliary supply of 24 V AC
and you wish to operate your Chiller at
460 V/3~/60 Hz, it is necessary to rewire the transformer. This transformer assignment must be carried out by an authorised, trained member of staff
prior to installation, observing all safety requirements.
Note:
The guarantee is not affected by this
rewiring.
Note:
In its delivered state, the transformer is
defined to a supply voltage of 400 V.

Commissioning
The Chiller has a red (optionally available in black)
master switch (see (2), Figure 1-4). Rotate it by a
quarter-turn in a clockwise direction to ready the
machine for operation.
6.1
Cooling medium
As standard, these units are not suitable for operation below the prescribed minimum temperature (see
chapter 15.4), unless you have selected the option
"winter control" for an extended ambient temperature range.
Generally speaking, a water-glycol mixture with a
maximum glycol proportion of between 20 and 34 %
by volume should be used as the cooling medium.
We recommend our ready-mixed "Cooling medium
for chillers" (see chapter 11). Other water-glycol
mixtures may be possible in individual cases, but
only by arrangement with the manufacturer. For
further information, please refer to chapter 8.

Filling the cooling medium
Ensure that any shut-off valves built into the
cooling medium circuit are open.
Fill the cooling medium into the Chiller tank via
the filling nozzle (see (1), Figure 27).
Page 15 of 104
EN
6 Commissioning
EN
The correct fill volume (between minimum and
maximum) may be read from the water level
display (see (2), Figure 27) on the outside of the
tank without having to open the door of the Chiller.
-
Note:
With a water-cooled condenser (optionally available), you must activate
the external condenser circuit for the
condenser (optionally by the operator). Check the connection lines and
pipe connections for leaks during
commissioning.
Note:
If the compressor and the condenser
fan fail to start up, the temperature of
the filled cooling medium is lower than
the setpoint temperature. You should
therefore temporarily reduce the setpoint temperature (see chapter 7).

Switch the Chiller on and off:
When switching the Chiller on for the first time,
please note that after pressing the master switch
(see (2) Figure 1-4) and ending the reboot phase,
the Chiller will be in standby mode. For this reason,
in order to switch it on, it is additionally necessary to
press the key combination "set" + "C". The Chiller is
switched off into standby mode by pressing the key
combination "set" + "F". Alternatively, the device can
also be disconnected from the mains directly via the
main switch (see also Figure 30).
Note:
The "Out" display is identical to the inlet
temperature shown during operation.
Apart from these basic functions (see also Figure
30), changes to the parameters may only be made
in the appropriate levels (see chapter 7.2.2).
Note:
The Chiller can only be switched into
standby mode in its original state (display of the inlet temperature during
operation).
Temperature displays
During operation, as well as the inlet temperature
(OUT), it is also possible to display the ambient
temperature (Anb) (only with optionally available
external temperature sensor) and the temperature
on the plate heat exchanger (anti-freeze sensor)
(TA). To do so, press the "F" or "C" keys during
operation until the required sensor is displayed, and
confirm your selection with "set". Pressing the "set"
key again will return you to the start menu.

7.2.2 Access levels
The parameters are accessed via menus, which are
located at three different levels.
Beispiel:
The parameter dLP allows you to set the delay time
of the low-pressure switch when starting up the
compressor (between 0-60 sec.). This parameter is
located in menu _di. This in turn is accessed via the
customer level.
The following diagram illustrates the system and
provides an overview of the three levels and their
menus. The parameters for the respective menus
may be found in chapter 7.
For simplification purposes, the basic level is referred to below as "BS", the customer level as "CU,
and the manufacturer level as "MN". Access to the
basic level is achieved by holding down the "set"
key (for approximately 2 seconds). The customer
level can only be accessed by entering the customer
password: 22. The manufacturer level is reserved
for trained service staff and is only accessible by
entering the manufacturer password. This password, together with the parameters for the manufacturer level, is not covered by this documentation but
may be requested from our technical service (see
chapter 9 for service contacts). Access to the
respective levels is explained in greater detail in

As a general rule, there are two different operating modes:
No.:
Operating mode
Application
1
Absolute (fixed value
control)
To be used if the application requires a constant medium temperature
2
Relative (ambient temperature-led control)
To be used if the application requires a medium temperature that varies depending
on the ambient temperature. Adjustment of the medium temperature to the ambient
temperature may be set here (e.g. so that the medium temperature is always 2°C
below the ambient temperature). However, it is limited by the limits PJr and PYr.
This application requires an external temperature sensor (optionally available)
3
Combined control
To be used when a combination of the relevant and absolute operating modes is
required. Depending on the ambient temperature, the target value is thus either
constant (absolute) or variable (relative). With due regard for the adjustable upper
and lower limit values.

Operating mode 2 – Relative (ambient temperature-led control)
To be used if the application requires a medium temperature that varies depending on the ambient temperature.
AMB = Ambient temperature

Set value = AMB + PSr
For the majority of applications, the set value must be

Fig. 39: Changing the operating mode
In order to switch the device to ambient temperature-led control, you will first need to access the
customer level. From there, you have the option of
changing the operating mode from absolute (ABS)
to relative (rEL) via the _Pr menu. All other adjustable parameters in the _Pr menu are described
under chapter 7.
Note:
With combined control, other parameters (e.g. PJr) must be taken into account.
Fig. 40: Cooling circuit with HGBP valve
7.2.6 Hot gas bypass control (optional)
A hot gas bypass control (hereinafter abbreviated to
HGBP) refers to a circuit with a controllable bypass
circuit from the high-pressure to the low-pressure
side (see P+ID cooling circuit) with an infeed
between the expansion valve and the evaporator
coil (see Figure 40).
Key to Figure 40:

Compressor

Expansion valve
Evaporator coil
HGBP control valve
The control valve (5) in the bypass circuit remains
closed when the cooling demand is high. The Chiller
will then supply its full output. If the required output
is reduced, the HGBP valve is continuously opened
via the controller. Hot gas will then flow via the bypass circuit to the evaporator coil input (4). There, it
is mixed with the refrigerant flowing out of the expansion valve and cooled down. As a result, the
mixture partially evaporates in the supply line to the
evaporator coil, causing the evaporation temperature to rise, and the cooling output to decrease.
Overheating of the extracted gas upstream of the
compressor is monitored and regulated by the expansion valve.
The HGBP control is used if an hysteresis of < 2 K
is required. The maximum medium temperature
hysteresis achievable with this control is 0.5 K. If
Page 27 of 104
7 Operation
EN
there is an HGBP valve built into the Chiller, the
following parameters may be set:
PSr = Set value
Pdr = Hysteresis (switching difference)
Hrr = Difference between set value PSr and
operating point of the bypass valve
Hdr = Hysteresis of bypass
Set value bypass = PSr + Hrr
7.3
Setting the temperature alarms
Adjustment of the alarm levels is a standard function
available on all models. Depending on your application, there are two logic systems available for alarm
reproduction (see Table 12):
Absolute
Relative
Logic
The HGBP valve opens if the medium temperature
is below PSr + Hrr – Hdr. The HGBP valve closes if
the medium temperature is above PSr + Hrr.
The pre-alarms (ALr and AHr)
will sound if the entered minimum and maximum temperatures are undercut or
exceeded.
Absolute
Parameter: POr (see Table 13)
POr = ABS
PLr = Minimum temperature pre-alarm
PHr = Maximum temperature pre-alarm
If the liquid temperature differs significantly
from the target value, the pre-alarms will
sound (ALr or AHr).
Note:
For machines with 32 kW and 40 kW, the
parameter eBP must additionally be
selected.
eBP = Activation of the HGBP with dual
circuit (enter "YES").
Relative
Pdr
Parameter description
Parameter: POr (siehe Tabelle 13)
POr = REL
Pbr = Differenz zu POr
E.g. The inlet temperature (PSr) > PSr +
Pbr  Pre-alarm (AHr) over-temperature.
For liquid temperature < PSr - Pbr  Prealarm under-temperature (ALr)

Caution!
Maintenance work on the circuit may
only be carried out by specialist refrigeration firms as per Directive (EC)
307/2008. We therefore advise you to
sign a maintenance contract which
includes annual inspection of the cooling circuit (European Directive EC No.
842/2006 / F Gases Directive). Directive (EC) 842/2006 or Chemical Climate
Protection Directive.
Inspection and maintenance
Regular, professional inspection and maintenance
(once a year is recommended) and the sole use of
original spare parts is crucial for fault-free operation
and a long service life of the Chiller. With this in
mind, we recommend that you sign a maintenance
agreement.
Note:
We offer a maintenance service!

Cooling medium
8.2.1 General remarks
When cooling the water-glycol mixture in an open
circuit, always remember that solid residues, algae,
deposits and corrosion can damage the Chiller.
Residues will always impair the performance of the
Chiller. Satisfactory conditions can rarely be achieved without water treatment. Ensure that deposits
and corrosion are avoided, even under extreme
conditions, by means of regular monitoring of the
cooling medium quality and treatment of the cooling
medium.

The cooling medium must not cause any limescale
deposits or loose debris. In other words, it should
have a low level of hardness, particularly carbonate
hardness. Particularly when cooling in circulation
mode, it is especially important that the carbonate
hardness is not too high. On the other hand, the
water should not be so soft that it attacks the materials.
When recooling the cooling water, the evaporation
of large quantities of water must not cause an increase in the salt content, since electrical conductivity increases as the concentration of dissolved
substances rises, and the cooling medium thereby
becomes more corrosive. For this reason, not only is
it always necessary to add a corresponding quantity
of fresh water, but also to remove part of the enriched cooling medium.
Furthermore, the properties of the water used must
not deviate from the following list of hydrological

Caution!
The cooling medium may thicken as a
result of evaporation. With a full exchange of cooling medium, you can adjust the
values to the framework conditions. Distilled or deionised water should only be
used in Chillers designed specifically for
this purpose (see data sheet, chapter
15.4).
8.2.3 Preparation and care
Depending on the type of installation to be cooled,
certain requirements are placed on the cooling medium. According to the level of contamination and
the size and design of the Chillers, a suitable process is used to prepare and/or maintain the cooling
medium. The most common types of contamination
and most frequently used techniques to eliminate
them in industrial cooling are shown in the following
table:
Type of impurity
Mechanical contamination
High level of hardness
Rittal recommends the use of "cooling medium for
chillers" (water-glycol mixture). This is a readymixed solution and is therefore suitable for immediate use (without the need for mixing) (see Table 19 +
20).

8.2.5 Monitoring the cooling medium
-
-
-
-
Regularly check the fill level of the cooling medium tank
Regularly check the quality of the cooling medium, and if necessary, improve it as described
under 8.2.3.
Regularly measure the glycol content using a
refractometer (see Figure 42). If you have any
questions, please contact our service department.
In order to prevent the formation of fungus and
algae, the cooling medium should be replaced at
least once a year. The use of pure water may
also cause the formation of fungus or algae.
If the Chiller is used under certain physical conditions (Tw < 10°C), condensation may form in
the system. This can be minimised by means of
suitable insulation or the optionally available
ambient temperature-led control.
When cleaning, please proceed as follows:
1. First, decommission the unit by switching off the
power supply to the master controller and
securing it against reactivation.
2. The condenser membranes are located on the
rear of the Chiller (see (1) Figure 43). To expose them, first remove the protective grille as
described under chapter 5.7 and/or remove the
optionally installed filter mat.
3. Next, clean the condenser with compressed air
(see Figure 44) and then fit the protective grille
and/or the filter mat again.

Caution!
The manufacturer's guarantee and warranty will be invalidated in case of improper use and treatment of the Chiller. In
order to avoid problems in the cooling/heat
transfer circuit (even on water-cooled
devices), observance of the VEB cooling
medium guidelines (VGB-R 455 P) is essential (for reference sources, please refer
to chapter 12).
8.3
Cleaning the condenser
In order to ensure problem-free operation of the
Chiller, the membranes of the air-cooled condenser
must be kept clean. Cleaning should take place at
regular intervals (at least once per half year),
whereby the frequency depends on the level of
contamination in the installation rooms.
Oily ambient air, in conjunction with dust, will result
in increased levels of contamination of the condenser membranes. In such cases, thorough cleaning
with compressed air is only possible under certain
circumstances. In such cases, the additional use of
a metal filter mat is required (see chapter 5.7).
Page 42 of 104
Fig. 44: Clean the condenser
When cleaning, it is essential to observe the safety
notices and warnings below.
9 Troubleshooting
Danger!
Disconnect the Chiller from the power
before carrying out any maintenance and
inspection work.
Danger!
Temperatures of up to 60°C may occur
inside the unit. Wait around 10 minutes
after switching the unit off to give the line
sufficient time to cool down.
Danger of cuts!
The condenser membranes have sharp
edges. Always wear gloves for your personal safety.
Caution!
Risk of damage to the condenser membranes if using excessive compressed air
force.
Meter the compressed air carefully to
avoid damage.
8.4
Cleaning the filter mat (optional)
The metal filter mat may likewise be cleaned using
compressed air. To do so, remove it from its holder
(see chapter 5.7).
8.5
Draining the cooling medium tank
Empty the cooling medium tank directly via the tank
drain nozzle (see (1) Figure 45) or using a hose into
a container. When disposing of the cooling medium,
always observe the locally valid water protection
guidelines.

EN
Troubleshooting
Whilst operational, the Chiller operates safely by
keeping the inlet temperature of the cooling medium
at the set level. Possible reasons for a deviation
from the setpoint may include:
- Excessive cooling demands
- Ambient temperature too high
- Failure to observe the necessary distances
- Contaminated evaporator coil
- Contaminated condenser
- Lack of refrigerant
- Insufficient cooling medium level in the tank
- Cooling medium temperature set too low
- Incorrectly set parameters
The malfunctions must only be rectified by trained,
specialist personnel. For fault analysis, please consult Table 14-15 or speak to our service department:

10 Decommissioning and disposal
EN
10
Decommissioning and disposal
Decommissioning and disposal of the Chiller may
only be carried out by authorised, specialist personnel. The unit will need to be deactivated by disconnecting it from the mains.
10.1 Decommissioning
If the Chiller is out of service for a long period (more
than six months), the cooling circuit will need to be
drained. This will prevent the evaporation of water,
and the water-glycol ratio of the cooling medium will
not be altered (the pump seal could be destroyed
due to glycol thickening). To decommission, please
proceed as follows:
- Disconnect the unit from the power supply and
protect against reactivation.
- Dismantle the connections of the cooling medium
circuit.
- Drain the cooling medium circuit as described
under chapter 8.
- To recommission, proceed as described under
chapter 6.
Certification to
BGR 500 chapter 2.35 and DIN EN 378-2
on the inspection of cooling systems
Note:
If a system is modified or remains out of
service for more than 2 years, it will need
to be re-inspected and re-certified. Modifications shall apply in the following circumstances:
If a system is opened and converted
to a different refrigerant
A stationary system is moved elsewhere
An existing system is extended or
converted
Or major improvements are carried
out.
10.2 Disposal
- When disposing of the cooling medium, always
observe the locally valid water protection guidelines. In Germany this is the Federal Water Act
(Wasserhaushaltsgesetz).
- For proper disposal of the Chiller, please notify
your supplier or our service department.
Caution!
Intentional release of the refrigerant is
prohibited. Refrigerant must be professionally disposed of.
