When the Need Arises
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.
• Turning on switch SW on the outdoor unit PCB will extend the
cooling operation range to 14°F (–10.0°C).
Installing an air direction adjustment grille (sold separately) will
further extend the operation range to –4°F (–20.0°C).
Please consult your dealer.
• Installing a drain pan heater (sold separately) will further
extend the heating operation range to –13°F (–25.0°C).

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.
Display lamps
Case Description / what to check
The OPERATION lamp is off,
but the air conditioner is
operating.
• Is the display brightness set to “Off”?
• CLEAN operation is being performed.
It is possible to stop CLEAN operation while it is in progress.
(If this does not suit your preferences, set CLEAN to “Off”.)
The display lamps on the main
unit are dark.
• Is the display brightness set to “Low”?
Others
Case Description / what to check
The air conditioner suddenly
starts behaving strangely during
operation.
• 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.
The WEEKLY TIMER does not
operate according to the settings.
• Check if the ON/OFF TIMER and the WEEKLY TIMER are set to the same time.
Change or deactivate the settings in the ON/OFF TIMER.

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.
