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.

Do not spray the air conditioner unit with any deodorizers.
Others

The ceiling and walls around the
indoor unit are black and dirty�
• Due to the circulation pattern of the air and static electricity, the air conditioner is causing
airborne dirt and dust to stick to walls and other surfaces. Depending on the wallpaper type,
dirt may adhere more easily. A thorough cleaning of the area around the air conditioner is
recommended.
Notes on the operating conditions
• If operation continues under any conditions other than those
listed in the table,
− A safety device may activate to stop the operation.
− Dew may form on the indoor unit and drip from it when COOL
or DRY operation is selected.
