• OPERATING INSTRUCTIONS •
Even if these items are checked, when the unit does not recover from the
trouble, stop using the air conditioner and consult your dealer.
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 7
The horizontal vane does not
move.
• Is the horizontal vane installed correctly?
• Is the fan guard deformed?
The unit cannot be operated
for about 3 minutes when
restarted.
• This protects the unit according to instructio ns from the microprocessor. Please
wait.
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 flow 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 around 1 hour, the direction
of the air flow is automatically set to position
(1) to prevent water from condensing and
dripping.
• In the heating operation, if the air flow temperature is too low or when defrosting is being done, the horizontal vane is automatically
set to horizontal position.
The operation is stopped for
about 10 minutes in the heating operation.
• Defrosting of the outdoor unit is being
done.
Since this is completed in max.10 minutes,
please wait. (When the outside temperature
is too low and humidity is too high, frost is
formed.)
The unit starts operation by
itself when the main power
is turned on, though it isn’t
operated with 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 operation automatically in the same
mode as the one set with the remote controller just before the shut off of the main power.
Refer to “Auto restart function” page 5 .
Multi system
The indoor unit which is not
operating becomes warm and
a sound, similar to water flowing, is heard from the unit.
• A small amount of refrigerant continues to
flow into the indoor unit even though it is
not operating.
When heating operation is
selected, operation does not
start right away.
• When operation is started during defrosting
of outdoor unit is done, it takes a few minutes
(max. 10 minutes) to blow out warm air.
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.
• In the heating operation, water condensed
on the heat exchanger drips down.
• In the heating operation, the defrosting operation makes water frozen on the outdoor
unit melt and drip down.
The fan of the outdoor unit
does not rotate even though
the compressor is running.
Even if the fan starts to rotate,
it stops soon.
• When the outside temperature is low during cooling operation, the fan operates
intermittently to maintain sufficient cooling
capacity.
White smoke is discharged
from the outdoor unit.
• In the heating operation, vapor generated
by the defrosting operation looks like white
smoke.
Symptom Explanation & Check points

out with the air.
Sound
Cracking sound is heard. • This sound is generated by the expansion/
contraction of the front panel, etc. due to
change in temperature.
The sound as burbling is
heard.
• This sound is heard when the outside air is
absorbed from the drain hose by turning on
the range hood or the ventilation fan, making
water flowing in the drain hose to spout out.
This sound is also heard when the outside air
blows into the drain hose in case the outside
wind is strong.
