OPERATING INSTRUCTIONS

Symptom
Explanation & Check points
Indoor Unit
The unit cannot be operated.
• Is the breaker turned on?
• Is the power supply plug connected?
• Is the ON timer set?
Page 12
The unit cannot be operated for about 3 minutes
when restarted.
• This protects the unit according to instructions from the micropro-
cessor. Please wait.
The fan stops during the DRY operation.
• In DRY operation, the unit operates using the same refrigerant circuit
as in COOL operation. DRY operation time has to be reduced in or-
der to lower humidity without much room temperature decreasing. So
the compressor sometimes stops, and at the same time the indoor
fan stops. This prevents water condensed on the heat exchanger
from evaporating again.
Mist is discharged from the air outlet of the
indoor unit.
• The cool air from the unit rapidly cools moisture in the air inside the
room, and it turns into mist.
The swing operation of the HORIZONTAL
VANE is suspended for a while, then restarted.
• This is for the swing operation of the HORIZONTAL VANE to be
performed normally.
The air
fl
ow direction changes during operation.
The direction of the horizontal vane cannot be
adjusted with the remote controller.
• When the unit is operated in COOL or DRY mode, if the operation
continues with air blowing down for 0.5 to 1 hour, the direction of
the air
fl
ow is automatically set to upward position to prevent water
from condensing and dripping.
The unit starts operation by itself when the main
power is turned on, but isn’t received sign from
the remote controller.
• These models are equipped with an auto restart function. When
the main power is turned off without stopping the unit with the
remote controller and is turned on again, the unit starts oper-
ation automatically in the same mode as the one set with the
remote controller just before the shutoff of the main power.
Refer to “Auto restart function”.

The indoor unit discolors over time.
• Although plastic turns yellow due to the in
fl
uence of some factors
such as ultraviolet light and temperature, this has no effect on the
product functions.
Outdoor Unit
Water leaks from the outdoor unit.
• During COOL and DRY operations, pipe or pipe connecting sections
are cooled and this causes water to condense.
Remote controller
The display on the remote controller does not
appear or it is dim. The indoor unit does not
respond to the remote control signal.
• Are the batteries exhausted?
Page 7
• Is the polarity (+, -) of the batteries correct?
Page 7
• Are any buttons on the remote controller of other electric appliances
being pressed?

HEN YOU THINK THAT TROUBLE HAS OCCURRED
Even if these items are checked, when the unit does not recover from the trouble, stop using the air condi-
tioner and consult your dealer.
