5. 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.
6. 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.
