This happens when the air in the room is cooled into mist by the cold airflow during COOL

Signal communication may be disabled if an electronic-starter-type fluorescent lamp (such
as inverter-type lamps) is in the room. Consult your dealer if that is the case.
•
The remote controller may not function correctly if the transmitter is exposed to direct sunlight.
•
Is there a device in the room that redirects remote controller signals?
Some appliances such as TV speakers are equipped with these devices.
If there is such a device in the room, the signals it emits may interfere with signals from the
remote controller, preventing reception.

Air has an odor
Case
Description / what to check
The air conditioner gives off an
odor.

The room odor absorbed in the unit is discharged with the airflow.
We recommend you to have the indoor unit cleaned. Please consult your dealer.

The indoor unit is blowing out room odor it has absorbed (the smell of walls or carpeting,
furniture, clothes, and so on).
If the air conditioner has been used for a long time, there is a chance that a dirty heat
exchanger or fan are emitting an odor.
We recommend you to have the indoor unit cleaned. Please consult your dealer.
Do not spray the air conditioner unit with any deodorizers.
