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
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 hasn’t received
sign from the remote controller.
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 6
• 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 upward 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
• 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.
