Emitter:
Packaging:
The QRL LST cover is designed to accommodate a standard
HI-LO round top emitter, easy to clean with no sharp edges.
Recommended connection configuration for NHS applications is
bottom opposite end (BOE). All standard connections are ½” BSP.
The QRL LST is supplied in two packs, the second pack containing
the cover can be supplied at the 2nd fix stage to avoid any on-site
damage that could occur during the 1st fix installation stage. The
HI-LO round top emitter is picture framed in heavy duty cardboard
with integral hanging lug protection and vacuum sealed in heavy duty
polythene. The cover is packaged in a heavy duty cardboard box and
lid with internal polystyrene support to give complete protection.
Cover:
The QRL LST cover comprises of a strong single piece 1.6mm gauge
iron phosphate and powder coated cover that is quick and easy
to install. The unique design allows it to be fitted over a standard
HI-LO round top emitter. The cover is forward hinged, allowing
easy access to the emitter for internal cleaning and maintenance.
This can be done by one person as the weight of the cover is fully
supported by the hinge. The hinge pins can be can be fully retracted
to allow the cover to be completely removed for deep cleaning.
There is a simple locking device to prevent unauthorised access. All
external surfaces are flat wipe clean surfaces, all external corners
are rounded to prevent injury.
The HI-LO round top emitter
is supplied with 1 x ½” BSP zinc plated air
vent and blank plus 6 x ant-vibration plastic saddles
for use with the wall brackets.
Wall Brackets:
All radiators in the range are supplied with two or more brackets
depending on the length of the emitter and two heavy duty hinged
brackets per cover. Brackets supplied with single and double
convectors provide a wall clearance of 25mm to the rear face of
the radiator.
The cover can be wall mounted either without plinth at a minimum of
50mm from the floor for types 11 and 21 and 100mm from the floor for
type 22 or with a plinth at 100mm from the floor. Plinths are provided
as an optional extra at floor level to conceal pipework and prevent
burns from exposed pipework carrying water above 43˚C. Any
exposed pipework fitted below the LST cover without a plinth must
be securely insulated or “boxed in” to comply with NHS regulations.
Outputs:
Quality:
All radiators have been manufactured and independently tested by
an EN442 accredited test laboratory to BS EN442 and fully comply
with the NHS Estates Health Guidance notes for ‘Safe Hot Water
and Surface Temperature’ and HSE health services information
sheet ‘Managing the risks from hot water and surfaces in health
and social care’ with a maximum surface temperature below 43˚C
at a maximum flow temperature of 80˚C / 60 ˚C return or 75˚C
flow / 65˚C return.
All radiators are CE marked and manufactured under a BS EN ISO
9001: 2008 quality system accepted by BSI.
Finish:
All radiators are primed and epoxy polyester powder coated by
electrophoresis to ensure all edges are coated. The covers are
iron phosphate and powder coated by electrophoresis all exposed
paint surfaces are finished in an antimicrobial coating to RAL9016.

Hardware:
Warranty:
All radiators are supplied under warranty for a period of 10 years
in respect of defective materials or manufacture. The standard
conditions of sale apply to all transactions. A copy is available on
request.
Testing:
All radiators are individually high pressure tested to 13 bar and are
suitable for a working pressure of up to 10 bar.
Installation:
Thermostatic Radiator Valves:
For indirect or closed circuits only with a maximum working
temperature of 80˚C. The system should be designed in
accordance with the British Standard Code of Practice for Water
Based Heating Systems in Buildings BS EN 128:2012+A1:2014
and BS EN 12831: 2003. The installation of the system and
commissioning of the system should comply with BS EN
14336:2004. On completion of the installation the system should
be properly flushed and filled in accordance with the British
Code of Practice for the Treatment of Water in Domestic Hot
water Central Heating Systems BS 7593: 2006, Part L of the
Building Regulations and Good Practice Guidance for Scotland.
QRL strongly recommend the use of corrosion inhibitor for all
applications. Failure to observe these standards may invalidate
the manufacturer’s warranty. Single feed indirect cylinders are
not recommended as the possibility of aeration due to water
interchange may lead to corrosion.
External control head – consists of a 15mm angled valve body
fitted to the emitter inside the LST cover and linked by capillary
tube to an external TRV head. The head is secured by simply
tightening the unit thru the pre-formed knock out at the top side
of the LST cover. This can be positioned on the RH or LH side of the
cover allowing total user flexibility. A specially designed grip on the
TRV head facilitates the use by people with limited hand mobility
and can be pre-set to the desired temperature required. These
valves are unsuitable for single pipe systems.
Tapping to Tapping Dimensions
All valve bodies are unidirectional and must always be fitted to the
flow side of the emitter
Internal control head – consists of a 15mm angled valve body and
control head fitted to the emitter inside the cover with an external
capillary sensor attached to the underside of the cover. The control
head can be pre-set to the desired temperature and is tamper
proof being only accessible to authorised personnel by simply
unlocking the hinged LST cover.
Can be obtained by subtracting 5mm from the nominal emitter length.

CONNECTION CENTRES
DETERMINATION OF PRESSURE DROP
IN RADIATORS
To calculate flowrates in Kg/hr:
Output (Watts) / 4.19KJ/Kg/k (Specific heat
capacity of water / ˚C) / Temp. Drop (˚C) x 3.6
E.g. 1000W / 4.19 / 10 x 3.6 = 85.92 Kg/hr
To calculate pressure drop in kPa:
Δp= K x (qmd) where Δp = pressure drop (kPa)
K = constant from graph
qm = flowrate (Kg/hr)
d = index from graph

1 L/hr = 1 Kg/hr
1 mbar = 100 pa
1mm/watergauge = 9.81 pa
Note:
Lug positions on 600mm cover length
for T11 will be 238mm from each end.
A third pair of lugs are fixed centrally
on radiators 1800mm long and above.

Conversion Information (Delta T factors)
The heat outputs quoted in this publication are based on ΔT50˚C to calculate other operating conditions, the following example should be used:
Example: Add flow water temperature (75˚C) and the return water temperature (65˚C) together (140˚C), divide by two (70˚C) and then
subtract the room temperature (20˚C). This will give you a ΔT factor of 50˚C. For ΔT factors other than 50˚C multiply the catalogue
figure by the conversion factor shown below:

Allow 150mm (6”) wall clearance on both sides of the emitter to allow
fitting of the LST cover. If an external TRV head is fitted, a further
100mm (4”) clearance is required on the side where the TRV head is to
be fitted.
2.
Allow 400mm (800 cover), 350mm (650 cover), 200mm (500 cover) wall
clearance on the top of the emitter to allow fitting of the LST cover.
The bottom of the LST cover must be 100mm from the floor if fitted
with a plinth, or minimum 50mm from the floor for types 11 and 21 and
100mm from the floor for type 22 without plinth to allow for effective
convection.
Check the emitter has been correctly fitted and set 120mm from the
floor.
Please refer to the cover drilling chart for screw fix positions, fix the
cover brackets to the wall as vertically level as possible
If the cover is fitted in an alcove or below a shelf, minimum clearance
from the top of the cover must be 100mm.
Unscrew the hinge pins from the outside of the cover using a flat head
screwdriver, fit the cover then re-tighten the hinge pins to secure the
cover.
4.
All emitters must be hung on the short side of the bracket maintaining
25mm away from the wall.
For security purposes the cover can be locked by using the nuts
provided on the studs at the bottom of the bracket.
5.
The cover drilling chart is set up to achieve a floor distance of 100mm
to the bottom of the LST cover. For other dimensions adjust dimension
‘230mm’ accordingly.
The emitter drilling chart is set up to achieve a floor distance of 100mm
to the bottom of the LST cover. For other dimensions, adjust ‘193mm’
accordingly.

Note: The screw position from the side of the emitter is 83mm at the top
and 78mm at the bottom so that the screw head clears the rear flange of
the cover when closed.
3.
Please refer to emitter drilling chart for screw fix positions. Fix the
brackets to the wall, then adjust the height of the emitter to achieve
120mm from the floor.
COVER
E.g. To achieve a floor distance of 50mm to the bottom of the LST cover,
reduce the ‘230mm’ dimension by 50mm to 180mm.
E.g. To achieve a floor distance of 50mm to the bottom of the LST cover,
reduce the ‘193mm’ dimension by 50mm to 143mm.
