Sound of refrigerant liquid flowing inside unit
●
Sound of drainage water through drain pipe
●
Cracking sound due to temperature changes of parts
Indoor odor components, cigarette odor and cosmetic odor accumulated
in the air conditioner and its air is discharged.
Unit inside is dusty. Consult your dealer.
Indoor moisture is cooled by cool wind and accumulated by dewdrop.
Cleaning is necessary because unit inside (heat exchanger) is dirty.
●
Consult your dealer as technical engineering is required.
During defrost operation
●
Fan rotating makes operation smoothly.
●
Fan may sometimes rotate because of drying heat exchanger due to
●
settings.
When air discharge temperature is low or during defrost operation,
●
horizontal wind flow is made automatically.
Flap position is occasionally set up individually.
●
When wind-direction is changed, flap operates after searching for
standard position.
Dust accumulation inside indoor unit is discharged.
The indoor unit is initially designed to control the indoor temperature
detected by the built-in room sensor inside the indoor unit.
Due to indoor unit installation position, however, the buit-in sensor may
occasionally sense temperature improperly; for example, temperature
difference between the ceiling and floor, lighting apparatus, electric fan,
windows or waist-high partition walls, etc.
In this case, the unit does not operate properly at the desired temperature.
You may change the use of the temperature sensor inside the indoor unit
to that of the remote controller.
Then the desired room temperature can be controlled properly.
For details, consult your dealer.
