-Switching the appliance off: turn the function selector in position “0” and the thermostat in

the position, then remove the plug from the electrical outlet.

-Additional features: Front Safety Guards- prevent the front grill from touching the floor when the heater is tipped over forward.

-Convenient Carry Handle-allows for easy transport from room to room.

MAINTENANCE AND SERVICE

Always remove the plug from the power socket and allow the heater to cool. After the heater has cooled, clean it with a soft damp cloth, do not use detergents or abrasives. Periodically clean the air intake and outlet grilles during the period in which the heater is in use with a vacuum cleaner.

Should the heater not be in use over a certain length of time, store it in a dry place. This appliance has been built to provide many years of trouble free service.

In case of malfunction, do not try to repair the heater yourself: it may result in fire hazard or elec- tric shock. Call the nearest Service Center (see attached list of Service Centers).

ATTENTION

A safety device switches the fan heater off if it accidentally overheats. To reset the unit for normal operation, remove the plug from the mains socket for a few minutes, eliminate the cause of over- heating (e.g. air intake or outlet grilles obstructed) and then plug the fan heater back in again. Contact your nearest Service Center if the fan heater does not begin normal operation again.

The appliance is equipped with a double tip-over-switch for extra safety. This device turns the appliance off should it fall over or if it is not perfectly stable. To restart the appliance, simply place it upright again.
