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 fi 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 for the model of
your unit, serial number, date of installation. Please
also inform him regarding the fault.

otherwise the unit will be broken or could not reach
