Your heater is fitted with a safety device "Double Protector" that (1) switches off
the heater by thermal cut-off in the event of overheating or malfunction, It will
reset while the temperature reduce to a normal level. (2) Shuts off the heater by
thermal fuse in the event of overheating or malfunction and not operates by some
other accidental reason.
If overheating or malfunctions continue, return the heater to an Approved Service
Agent for examination.
The most common cause of overheating is deposits of dust or fluff entering the
heater, Ensure these deposits are removed regularly by unplugging the unit and
vacuum cleaning air vents and front grille.
SAFETY CONTROL
1. Light accumulated dust may be removed from the heater with a soft cloth. Wipe
the exterior surfaces of the heater occasionally with a cloth moistened (not
dripping wet) with a solution of mild detergent and water. Dry the case
thoroughly with a soft dry cloth before operating the heater.
2. The fan motor is lubricated by the factory, and will require no further lubrication.
3. No other user maintenance is required or recommended. If service is required,
send your heater to the nearest authorized service depot.
4. Store heater in a clean and dry place when not in use.
REMEMBER - portable electric heaters are designed for spot heating, or as a
supplementary heat source. They are not intended to be main sources of heat
during the normal heating season.
Note: There may be trace of smoke or odour when unit is first operated. Do not
be alarmed. This indicates that a drop of oil fell on the heating coil during the
manufacturing process. It will quickly evaporate, and should not re-occur.

CLEANING AND MAINTENANCE
This fan heater is equipped with a pilot light that glows whenever the heater is
plugged in and turned on. It will continue to glow even if the thermostat has cycled
the heating elements off. This feature is to prevent you from being unaware that
the heater is operating and maintaining the temperature of the room.
When you do not wish the heater to control the room temperature, turn the control
switch to O (off) and remove the plug from the electrical outlet.
