●
Is the voltage extremely high or low?
Is the circuit breaker "ON"?
●
Was the air fi lter cleaned?
●
Does sunlight fall directly on the outdoor unit?
●
Is the air fl ow of the outdoor unit obstructed?
●
Are the doors or windows opened, or is there any source
●

●
Is the set temperature suitable?
Notes
In quiet operation or stopping the operation, the following phenomena
●
may occassionally occur, but they are not abnormal for the operation.
(1)
Slight fl 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 fi lter and the evaporator regularly must be cleaned
to reduce the odor.
