AFTER SALE SERVICE AND WARRANTY

WHEN ASKING FOR SERVICE, CHECK THE FOLLOWING POINTS

CONDITION
If the remote controller is not transmitting a signal. Remote controller display is dim or blank.)
When it does not operate
When it does not cool well When it does not hot well

CHECK THE FOLLOWING POINTS
Do the batteries need replacement? Is the polarity of the inserted batteries correct?
Is the fuse all right? Is the voltage extremely high or low? Is the circuit breaker “ON”? Is the setting of operation mode different from other indoor
units?
Is the air filter blocked with dust? Does sunlight fall directly on the outdoor unit? Is the air flow of the outdoor unit obstructed? Are the doors or windows opened, or is there any source
of heat in the room? Is the set temperature suitable? Are the air inlets or air outlets of indoor and outdoor units
blocked? Is the fan speed “LOW” or “SILENT”?

Notes
In quiet or stop operation, the following phenomena may occassionally occur, but they are not abnormal for the operation. (1) Slight flowing noise of refrigerant in the refrigerating cycle. (2) Slight rubbing noise from the fan casing which is cooled and then gradually warmed as operation stops.
The odor will possibly be emitted from the room air conditioner because the various odor, emitted by smoke, foodstuffs, cosmetics and so on, sticks to it. So the air filter and the evaporator regularly must be cleaned to reduce the odor.
Please contact your sales agent immediately if the air conditioner still fails to operate normally after the above inspections. Inform your agent of the model of your unit, production number, date of installation. Please also inform him regarding the fault.
Power supply shall be connected at the rated voltage, otherwise the unit will be broken or could not reach the specified capacity.

NOTE: If the supply cord is damaged, it must be replaced by the special cord obtainable at authorized
service parts centers.
