Introduction
Testing undertaken by BSRIA conforms these heaters comply with DHSS Engineering and
Data DN4 and NHS Estates Health Guidance Note ‘Safe Hot Water and Surface
Temperature’ (1998).
These heaters are designed as a low level mounted product with air outlet discharge from the
top of the unit. LST function ensures the surface and grille temperature does not exceed 43°C
by measuring leaving air temperature and modulating the flow through the heat exchanger.
These heaters must not be installed in wet rooms or other high humidity areas.
These heaters are designed for use on standard two-pipe pumped central heating systems
with a maximum water temperature of 86° C and a maximum pressure of 6 bar (88lbs/in²).
Pipe connections are 22mm, Flow direction must follow that shown on the body of the
valve.
These heaters are classified as a fixed appliance and the electrical connection should be via a
3A fused spur. The fused spur must not be directly below the heater but should be accessible
after completion of the installation. All heaters must be earthed.
This heater is fitted with an integral room thermostat.
This heater is fitted with an air outlet thermostat pre-set to 34°C; and should not be adjusted
above 35°C.
To avoid the possibility of vibration these units must be fitted to a flat even surface.
These heaters are fitted with low temperature cut out stats and will not operate until a water
temperature of approximately 35°C is achieved.
If desired a remote room thermostat can be used in conjunction with this heater. Refer to the
manufacturer’s instructions supplied with the thermostat.
Please note the guarantee may be invalidated if this product is not installed and used in
accordance with these instructions.
For further details please contact our Technical Support on 01245 324560.
Installation Guide
1. Unlock and lower the front access panel using the keys supplied.

Fault Finding
1. The fan does not run on any speed setting.
a. Check the power supply is switched ON.
b. Check the fuse in the fused spur.
c. Check the wiring at the fused spur.
d. Check thermostat is calling for heat
e. Check the central heating is switched ON and hot water flowing through system.
f. Vent any trapped air from the system (with the heating system turned OFF).
2. No heat output.
a. Vent any trapped air from the system (with the heating system turned OFF).
b. Check the central heating is switched ON and hot water flowing through system.
c. Check thermostat is calling for heat
d. Balance the central heating system if installed on the same circuit as panel radiators and
increase the circulating pump speed if required.
e. Increase the boiler water temperature.
Providing the power supply is switched on and the room thermostat is calling for heat the
heater will switch on and off automatically with the central heating system.
In the event of difficulty please contact our technical help-line on 01245 324560. It would be
helpful if you do not disconnect the heater from the central heating system prior to calling.
Maintenance.
Warning! Isolate from the electrical supply before performing any work on the
unit.
The internal air filter is removable for servicing. To gain access to the filter, unlock and lower
the front access panel, remove the 2 screws from the filter enclosure panel and lift out.
Carefully lift and remove filter (see fig 3). The filter should be gently tapped to remove any
accumulated dust and vacuumed if necessary.
The coil fins are delicate so take care and only use a soft brush or vacuum cleaner to remove
any dust that may have accumulated.
To replace filter, reverse the removal instructions and ensure the lower front access panel is
securely locked.
The fan(s) and motors should not require servicing. Please contact your supplier if damaged.
Please note in the event of an engineer’s visit, Smith’s Environmental Products Ltd reserve the
rights to apply a call-out charge should the fault prove to be with the system or installation and
not the heater appliance.

2. Fix the unit to the wall via suitable fixings.
3. Connect the heating system flow and return pipes to the heater pipe work. Pipe entry/ exit
can be made through either the back of the unit or by using the Pipe Knockouts on the bottom
of the unit (See Fig 3). Do not use soldered fittings to connect the heater pipe work as the heat
generated may cause damage to internal wiring and components.
We recommend the use of full-flow service valves. The valves should be accessible after
completion of the installation. We also advise the fitting of an air vent at the highest point on
either the flow or return pipe to remove any air trapped within the system.
4. Open the full flow service valves (see above) and check for water leaks. Remove any
trapped air from the unit via the built in bleed screws as shown in the diagram below.
Note: Ensure the motorised valve is set to the Auto position.
5. Isolate the electrical supply

6. Connect the power supply from the fused spur (3 Amp) to the heater terminal block marked
Supply E N L (see fig 2) via the cable entry hole in the top chassis of the heater.
The fused spur must not be directly below the heater and must be accessible after the
installation is complete. All electrical work should be carried out in accordance with current
IEEE regulations.
7. To connect a room thermostat (not supplied) to the connection block on the heater remove
link and connect to terminals 7 & 8.
For further information refer to the room thermostat manufacturers instructions.
Fig 1
Commissioning
1. Turn on the electrical supply at the fused spur.
2. Turn the thermostat control (if fitted) to maximum.
3. Turn on the central heating system 4
4. If these heaters are installed on the same circuit as panel radiators balance the central
heating system.
5. If the installation is working correctly remember to reset the thermostat control to its required
setting.
6. Set the fan speed control to the desired position (see fig 2)
(Note To decrease motorised valve cycles it is recommended that the flow is reduced. (Please
ensure adequate flow through heater).
7. Lift up and close front access panel, ensure this is secure and locked in place with keys
provided.
8. Please leave this Installation & User Guide with the user for future reference.
Heating –see below
Ensure the central heating system is ON. Switch on the power supply to the unit. Set the
thermostat control (if fitted) to the desired temperature. Providing the water temperature
in the central heating system is more than 35°C and the thermostat (if fitted) is calling for
heat the product will switch on.
Note: Achieving higher output than shown in the above table will not be
possible by increasing flow rate, this is because due to LST function of the
heater. To achieve higher than shown outputs increase fan speed.
It is recommended that the model chosen is capable of maintaining the calculated heat loss at
medium heat output enabling the high speed setting to be used for faster heat up and the low
speed for maintaining temperature.
