Notes
In quiet operation or stopping the 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.
