BEFORE CONTACTING THE SERVICE REPRE-
SENTATIVE, CHECK THE FOLLOWING AGAIN
WHEN YOU THINK THAT TROUBLE HAS OCCURRED
Even if the above items are checked, when the air conditioner does not
recover from the trouble, stop using the air conditioner and consult your
dealer.
In the following cases, stop using the air conditioner and consult your dealer.
• When water leaks or drops from the indoor unit.
• When the left operation indicator lamp blinks.
• When the breaker trips frequently.
•
The remote control signal may not be received in a room where an electronic
ON/OFF type fluorescent lamp (inverter-type fluorescent lamp, etc.) is used.
•
Operation of the air conditioner may interfere with radio or TV reception in areas
where the reception is weak. An amplifier may be required for the affected
device.
• When thunder is heard, stop operation and disconnect the power supply plug
or turn off the breaker. Otherwise, the electrical parts may be damaged.
Answer (not a malfunction)
•
This protects the air conditioner according to in-
structions from the microprocessor. Please wait.
• This sound is generated by the expansion/con-
traction of the front panel, etc. due to change in
temperature.
• The air conditioner may suck in an odor adhering
to the wall, carpet, furniture, cloth, etc. and blow
it out with the air.
• In DRY operation, the unit operates using the
same refrigerant circuit as in COOL operation.
DRY operation time has to be reduced in order
to lower humidity without much room tempera
-
ture decreasing. So the compressor sometimes
stops, and at the same time the indoor fan stops.
This prevents water condensed on the heat
exchanger from evaporating again.
• This is the sound of refrigerant flowing inside the
air conditioner.
• This is the sound of condensed water flowing in
the heat exchanger.
•
This is the sound of the heat exchanger defrosting.
• This sound is heard when the outside air is
absorbed from the drain hose in turning on the
range hood or the ventilation fan and that makes
water flowing in the drain hose sucked up.
This sound is also heard when the outside air
blows into the drain hose in case the outside
wind is strong.
• When a ventilation fan or a gas cooker is used
in a room, the cooling load increases, resulting
in an insufficient cooling effect.
• When the outside air temperature is high, the
cooling effect may not be sufficient.
• The cool air from the air conditioner rapidly cools
moisture in the air inside the room, and it turns
into mist.
• This is the switching sound in turning on/off the
fan or the compressor.
• When the air conditioner is operated in COOL
or DRY mode, if the operation continues with air
blowing down for 1 hour, the direction of the air
flow is automatically set to horizontal to prevent
condensed water from dropping.
•
In the heating operation, if the air flow temperature is
too low or when defrosting is being done, the horizon
-
tal vane position is automatically set to horizontal.
Question
The air conditioner cannot
be operated for about 3
minutes when restarted.
Cracking sound is heard.
The air from the indoor unit
smells strange.
The fan stops during the
DRY operation.
The sound of water flowing
is heard.
The sound as burbling is
heard.
The room cannot be cooled
sufficiently.
Mist is discharged from
the air outlet of the indoor
unit.
Mechanical sound is heard
from the indoor unit.
The air flow direction
changes during operation.
The direction of the hori
-
zontal vane cannot be
adjusted with the remote
controller.
Question
Water leaks from the out-
door unit.
White smoke is discharged
from the outdoor unit.
Air does not blow out soon
in the heating operation.
The operation is stopped
for about 10 minutes in the
heating operation.
Hissing sound is some
-
times heard.
The room cannot be heated
sufficiently.
The swing operation of the
VERTICAL VANE is
suspended for about 15
seconds, then restarted.
In a multi-unit system, the
indoor unit which is not op
-
erating becomes warm and a
sound, similar to water flow
-
ing, is heard from the unit.
The air conditioner starts
the operation only with
the main power turned on,
though you do not operate
the unit with the remote
controller.
Answer (not a malfunction)
• During COOL and DRY operations, pipe or pipe
connecting sections are cooled and this causes
water to condense.
• In the heating operation, the defrosting operation
makes water frozen on the outdoor unit melt and
drip down.
•
In the heating operation, water drips from the heat
exchanger. This is not a malfunction. However, if
you have any trouble with water dripping, consult
your dealer for drainage work. Please note that
we cannot provide drainage work in such climate
that the outdoor unit may get frosted.
• In the heating operation, vapor generated by the
defrosting operation looks like white smoke.
• Please wait as the air conditioner is preparing
to blow out warm air.
• Defrosting of the outdoor unit is being done
(Defrosting operation).
Since this is completed in 10 minutes, please
wait. (When the external temperature is too low
and humidity is too high, frost is formed.)
• This is the sound when the flow of refrigerant
inside the air conditioner is switched.
• When the outside air temperature is low, the
heating effect may not be sufficient.
• This is for the swing operation of the VERTICAL
VANE to be performed normally.
• A small amount of refrigerant continues to flow
into the indoor unit even though it is not operating.
•
These models are equipped with an auto restart
function. When the main power is turned off with
-
out stopping the air conditioner with the remote
controller and is turned on again, the air condi
-
tioner will start operation automatically in the same
mode as the one set with the remote controller just
before the shutoff of the main power.
Question
The air conditioner cannot
be operated.
The room cannot be cooled
or heated sufficiently.
The air from the indoor unit
smells strange.
The display on the remote
controller does not appear
or it is dim. The indoor unit
does not respond to the
remote control signal.
When a power failure occurs.
Check points or Remedy
• Is the breaker turned on?
• Is the fuse blown?
• Is the ON timer set? (Page 8)
• Is the temperature setting correct? (Page 7)
• Is the filter clean? (Page 10)
• Are there any obstacles blocking the air inlet or
outlet of the indoor or outdoor unit?
• Is a window or door open?
• Is the filter clean? (Page 10)
• Are the batteries exhausted? (Page 5)
• Is the polarity (+, -) of the batteries correct?
(Page 5)
• Are any buttons on the remote controller of other
electric appliances being pressed?
•
Does the air conditioner start operating again?
If the air conditioner had operated before the
power failure, as these models are equipped
with an auto restart function, the air conditioner
should start operating again. (Refer to Description
of “AUTO RESTART FUNCTION” on page 6.)
