WHEN 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 Explanation & Check points
Indoor Unit
The unit cannot be operated.
All LED lamps on the indoor
unit are blinking.
The horizontal vane does not
move.
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
restarted.
The airfl ow direction changes
during operation.
The direction of the horizontal
vane cannot be adjusted with
the remote controller.
The operation stops for about
10 minutes in the heating
operation.
The unit starts operation by
itself when the main power is
turned on, but isn’t received
sign from the remote controller.
In COOL/DRY mode, when
the room temperature reaches near the set temperature,
the outdoor unit stops, then
the indoor unit operates at
low speed.
The indoor unit discolors over
time.
Outdoor Unit
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.
Water leaks from the outdoor
unit.
White smoke is discharged
from the outdoor unit.
• Is the breaker turned on?
• Is the power supply plug connected?
• Is the ON timer set? Page 8
• Are the horizontal vanes installed correctly?
Page 11
• Are the horizontal vane and the vertical vane
installed correctly? Page 11
• Is the fan guard deformed?
•
This protects the unit according to instructions from the microprocessor. Please wait.
• The cool air from the unit rapidly cools moisture in the air inside the room, and it turns
into mist.
• This is for the swing operation of the HORIZONTAL VANE to be performed normally.
• 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 airfl ow is automatically set to horizontal position to prevent water from condensing
and dripping.
• In the heating operation, if the airfl ow temperature is too low or when defrosting is being done, the horizontal vane is automatically
set to horizontal position.
• Outdoor unit is in defrost.
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 controller just before the shutoff of the main power.
Refer to “Auto restart function” Page 5 .
• When the room temperature rises and the
outdoor unit turns on, the indoor fan starts
running according to the settings on the
remote controller.
• 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.

• 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.
• When a ventilation fan or a gas cooker is
used 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.
• When the outside temperature is low, the
heating effect may not be suffi cient.
• Please wait as the unit is preparing to blow
out warm air.
• Do you have an arrangement with your electric company for Demand Response?
