Problem Possible Cause Solution
After the power is
engaged, the power
indicator lig ht does not
illuminate and the
machine does not work.
The plug may not be
plugged well.
Check whether the plug is
properly inserted intothe
receptacle.
The temperature control
knob is not turned in
place.
Check whether the
temperature control knob
is turned to the ON
position.
The machine suddenly
stops during heating.
The temperature exceeds
the threshold of the
thermal cut-o .
Cool the machine before
use.

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.

Remark:
For electric local space heaters, the measured seasonal space heating energy efficiency 
s
cannot be
worse than the declared value at the nominal heat output of the unit.

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 operat-
ing the heater.
2. The fan motor is lubricated by the factory, and will require no further
lubrication.
3. No other user maintenance is required orrecommended. If service is
required, send your heater to the nearest authorized servicedepot.
4. Store heater in a clean and dry place whennot 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 operat-
ed. Do not be on the heating coil during the manufacturing process. It
will quickly evaporate, and should not re-occur.
CLEANING AND MAINTENANCE INSTRUCTION
Warning:This heatercannot achieve accurate temperature control of the
enviroment, and thus cannot be used as insulation device forstorage
