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.
• 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.
Description / what to check
• The air conditioner may malfunction due to lightning or radio.
If the air conditioner malfunctions, turn off the power with the circuit breaker and restart the
operation with the remote controller.
• Check that the jumper (J8) has not been cut. If it
has been cut, contact your dealer.
• Check if the ON/OFF TIMER and the WEEKLY TIMER are set to the same time.
Change or deactivate the settings in the WEEKLY TIMER.
• 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.
