● OPERATING INSTRUCTIONS ●
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.
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 hasn’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.
• Is the breaker turned on?
• Is the power supply plug connected?
• Is the ON timer set? Page 5
• Are the horizontal vane and the vertical vane
installed correctly?
• Is the fan guard deformed?
• When the breaker is turned on, the horizontal
vanes’ position will be reset in about a minute.
After the reset has completed, the normal horizontal vanes’ operation resumes. The same is
true in the emergency cooling operation.
• 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 4
• When the room temperature deviates from the
set temperature, 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.
Multi system
The indoor unit which is not
operating becomes warm and a
sound, similar to water fl owing,
is heard from the unit.
When heating operation is
selected, operation does not
start right away.
• A small amount of refrigerant continues to fl ow
into the indoor unit even though it is not operating.
• 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
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.
• 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.
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 3
• Is the polarity (+, -) of the batteries correct?
Page 3
• Are any buttons on the remote controller of other
electric appliances being pressed?
