6. Servicing & Maintenance
6.1 Maintenance
Always ensure that the main external electricity supply is switched off before
commencing any maintenance on this heater.
To obtain the best results from the heater, it is essential to avoid the accumulation
of dust and dirt within the unit on the air inlet and discharge grilles. For this reason
regular cleaning is necessary.
• Cleaning of the fan is best carried out with a soft brush.
• The product should be serviced annually.
• Servicing shall be undertaken by a competent person.
6.2 General
If the heater does not operate a competent service engineer should be called to
identify the nature of the fault.
All heaters are fitted with motor thermal protection.
Other faults in relation to the element, motor and wiring should be identified using
conventional fault finding techniques.
In the event that electrical components are replaced, please ensure that electrical
safety checks in accordance with the regulations in force in the country of use are
undertaken.
6.3 Thermal cut–out
The units are protected from overheating in the event of fan failure or an obstruction
of the free airflow, by thermal cut outs. If this happens the thermal cut outs switch off
the appliance. The appliance will not operate until the heater is disconnected from the
mains supply and it has cooled down.
If this fault re–occurs again, refer to the section ‘6.4 fault finding’.
