CONDITION CHECK THE FOLLOWING POINTS

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.
