W
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 conditioner and consult your dealer.
Symptom
Indoor Unit
The unit cannot be operated.
The unit cannot be operated for
about 3 minutes when restarted.
Mist is discharged from the air
outlet of the indoor unit.
The swing operation of the
HORIZONTAL VANE is
suspended for a while, then
EN
restarted.
The air fl ow direction changes
during operation.
The direction of the horizontal
vane/multi-fl ow vane cannot
be adjusted with the remote
controller.
The operation is stopped for
about 10 minutes in the heating
operation.
The unit starts operation by
itself when the main power is
turned on, though it isn't oper-
ated with the remote controller.
The multi-fl ow vane opens and
closes automatically.
The indoor unit which is not
operating becomes warm and a
sound, similar to water fl owing,
is heard from the unit.
The indoor unit discolors over
time.
Outdoor Unit
The fan of the outdoor unit does
not rotate even though the com-
pressor is running. Even if the
fan starts to rotate, it stops soon.
Water leaks from the outdoor
unit.
White smoke is discharged from
the outdoor unit.
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.

Explanation & Check points
• Is the breaker turned on?
• Is the power supply plug connected?
• Is the ON timer set?
• This protects the unit according to instructions
from the microprocessor. Please wait.
• The cool air from the unit rapidly cools mois-
ture in the air inside the room, and it turns into
mist.
• This is for the swing operation of the HORIZON-
TAL VANE to be performed normally.
• In the heating operation, if the air fl ow tem-
perature is too low or when defrosting is being
done, the horizontal vane is automatically set
to vertical position. The multi-fl ow vane is set to
the closed position.
• When the air conditioner is operated in COOL
or DRY mode, if the operation continues with air
blowing horizontally for 1 hour, the direction of
the air fl ow is automatically set to position (1)
to prevent condensed water from dropping. The
multi-fl ow vane is set to the closed position.
• The horizontal vane and the multi-fl ow vane
automatically moves in certain intervals to
determine its position, and then it returns to the
set position.
• 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.)
• 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 control-
ler just before the shutoff of the main power.
Refer to "Auto restart function".
• The multi-fl ow vane is automatically control-
led by a microcomputer according to the air
fl ow temperature and operation time of the air
conditioner.
• A small amount of refrigerant continues to fl ow
into the indoor unit even though it is not operat-
ing.
• Although plastic turns yellow due to the infl uence
of some factors such as ultraviolet light and
temperature, this has no effect on the product
functions.
• When the outside temperature is low during
cooling operation, the fan operates intermittently
to maintain suffi cient cooling capacity.
• 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 ice forming on the outdoor unit melt and
drip down.
• In the heating operation, vapor generated by the
defrosting operation looks like white smoke.
• Are the batteries exhausted?
• Is the polarity (+, -) of the batteries correct?
• Are any buttons on the remote controller of other
electric appliances being pressed?

heated suffi ciently.
• Is the fan setting appropriate? Please change
fan speed to High or Super High.
• Is the air outlet selection is set to 1 FLOW? Set
it to 2 FLOW.
• Is the fi lter clean?
• Is the fan or heat exchanger of the indoor unit
clean?
• Are there any obstacles blocking the air inlet or
outlet of the indoor or outdoor unit?
• Is a window or door open?
• It may take a certain time to reach the setting
temperature or may not reach that depending on
the size of the room, the ambient temperature,
and the like.
The room cannot be cooled
• When a ventilation fan or a gas cooker is used
suffi ciently.
in a room, the cooling load increases, resulting
in an insuffi cient cooling effect.
• When the outside temperature is high, the
cooling effect may not be suffi cient.
The room cannot be heated

smells strange.
• Is the fan or heat exchanger of the indoor unit
clean?
• The unit may suck in an odor adhering to the
wall, carpet, furniture, cloth, etc. and blow it out
with the air.
Sound
Cracking sound is heard.
• This sound is generated by the expansion/
contraction of the 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
fl owing 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.

• Transmit the setting information of the weekly
timer to the indoor unit again. When the informa-
tion is successfully received, a long beep will
sound from the indoor unit. If information fails to
be received, 3 short beeps will be heard. Ensure
information is successfully received.
• When a power failure occurs and the main
power turns off, the indoor unit built-in clock will
be incorrect. As a result, the weekly timer may
not work normally.
Be sure to place the remote controller where
the signal can be received by the indoor unit.
