●

In quiet or stop operation, the following phenomena may occassionally occur,
but they are not abnormal for the operation.

(1) Slight

owing 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

lter 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 speci

ed capacity.
