OVERHEATING SAFETY DEVICE
Your heater is fitted with a safety device that switches off the
heater in the event of overheating.
If the heater stops working, turn the heater off and inspect
blockage of inlet or outlet. Wait at least 5 minutes so the
protection system resets before attempting to restart the
heater.
If the heater fails to operate, the safety device switches the
heater off again, return the heater to your nearest service
center for examination or repair.
CLEANING YOUR FAN HEATER
1. Always disconnect the appliance from the main supply
before cleaning.
2. Clean the outside of the heater by wiping with damp
cloth and guff with a dry cloth.
3. Do not use Benzine or any other detergents/solvents or
chemical agents to clean the heater.
SERVICE
Hints before returning the appliance:
Is your household socket working properly?
Are all required switches in the "ON" position?
Ensure that the plug is firmly in the socket and switched on.
Ensure the heater if standing on an even surface.
