3. MOUNTING INSTALLATION

3.1 CEILING MOUNTING

The heater is intended for installation in a suspended ceiling mounted within or on the 'tee' bar supports. For optimum results do not
fit in ceilings higher than 3m. As air is only introduced through the front of the unit the heater may be sighted anywhere. The air
intake and discharge areas must be kept completely clear for a minimum of 1.5m from the front of the heater. In an area using
multiple units, heaters should be spread to provide an even heat distribution.



IMPORTANT! A minimum clearance of 205mm is needed between the bottom of the false ceiling and the original roof/ceiling
to allow installation of the heater.



IMPORTANT! DO NOT use plastic type diffusers as these may be damaged by the heat.



IMPORTANT! Ensure that the mounting surface / ceiling supports are capable of taking the additional weight of the heater
there are 2 eye hooks supplied with the heater that should be used if additional support of the heater is required.
When using the diffuser the four Z brackets provided should be attached to the side of the heater to enable the heater to be
supported by the 'tee' bar and immediately above the diffuser.

5. CONTROL

Standard temperature control is by adjusting the electronic thermostat knob located on the back of the heater.

6. MAINTENANCE

Note: Before examining or carrying out any maintenance ensure the heater has cooled down and is disconnected from the mains

supply.
The heaters are intended to operate for many years, problem free. All moving parts are factory lubricated and therefore should
require no service. Maintenance is limited to keeping both the inlet and outlet areas free from any accumulation of dust or any other
foreign materials. This is especially important immediately before the heating season. Any dust build up can be loosened using a
brush and a vacuum cleaner applied to the airways to ensure completed removal of any dust. When the heater is first turned on
after cleaning an unusual odour may be noted this is due to the dust particles which inevitably will be disturbed and will be burnt off
from the heating element.
If in any doubt always consult a qualified electrician for advice.

7. AUTO CUT OUT

This heater is fitted with a semi-automatic safety device to prevent overheating. The device will isolate the heating element while
the fan continues to operate. Should this occur, disconnect the heater from the mains supply for a minimum of 5 minutes, check
and remove any foreign materials around the airways. If the heater fails to operate or the safety cut out operates again, turn off the
heater and contact a qualified electrician.

NOTE: It is our policy to continually improve products and as such we reserve the right to alter data, specifications and component
parts without prior notice.
