Description / what to check
• Is there any furniture directly under or beside the indoor unit?
• Is the air conditioner in ECONO operation?
• Are the air filters dirty?
• Is there anything blocking the air inlet or air outlet of the indoor unit or outdoor unit?
• Is a window or door open?
• Is an exhaust fan turning?
• Depending on the room conditions, number of occupants, or outdoor temperature and
humidity, the set temperature may not be reached.
Description / what to check
• This happens when the air in the room is cooled into mist by the cold airflow during COOL
or other operation.
• If the drain hose is crushed or clogged, water from the indoor unit may be unable to drain
and start leaking. Stop operation of the unit immediately and contact your dealer.
Description / what to check
• The batteries may be exhausted.
Replace both batteries with new dry batteries AAA.LR03 (alkaline).
For details, refer to "Preparation Before Operation".
• 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.
• Infrared rays from smartphones and game consoles may interfere with signals from the
remote controller, preventing reception.
• The batteries may be exhausted.
Replace both batteries with new dry batteries AAA.LR03 (alkaline).
For details, refer to "Preparation Before Operation".
• If the remote controller activates other electric devices, move them away or consult your
dealer.
Description / what to check
• 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.
