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.
The air flow direction
changes during operation.
The direction of the horizontal vane cannot be adjusted with the remote controller.
Answer (not a malfunction)
• This protects the air conditioner according to instructions from the microprocessor. Please wait.
• This sound is generated by the expansion/contraction 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 temperature 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 spout out.
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.
• 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 horizontal vane position is automatically set
to horizontal.
WHEN YOU THINK THAT TROUBLE HAS OCCURRED
Question
Water leaks from the outdoor 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 sometimes 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 operating becomes warm and
a sound, similar to water
flowing, 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 condensed on
the heat exchanger drips down.
• 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 without stopping the air conditioner with the remote
controller and is turned on again, the air conditioner will start operation automatically in the
same mode as the one set with the remote controller just before the shutoff of the main power.
CAUTION:
• Earth the unit.
Do not connect the earth to a gas pipe, water pipe, lightning rod or the earth of a telephone. If the earthing is
incorrect, it may cause an electric shock.
• Install an earth leakage breaker depending on the place where the air conditioner is to be installed (humid places,
etc.).
If the earth leakage breaker is not installed, it may cause an electric shock.
Inspection and maintenance
• When the air conditioner is used for several seasons, the capacity may be lowered due to dirt inside the unit.
• Depending on the condition, an odor may be generated or dehumidified water may not drain out smoothly due to dirt,
dust, etc.
• It is recommended that the unit be inspected and maintained (charged) by specialist in addition to normal maintenance.
Consult your dealer.
Operating sound considerations
• Do not put an object around the air outlet of the outdoor unit. This may lower the capacity or increase the volume of the
operating sound.
• If an abnormal sound is heard during operation, consult your dealer.
Relocation
• When the air conditioner is to be removed or re-installed because of rebuilding, moving, etc., special techniques and work
are required.
WARNING :
Repairs or relocation should not be done by the customer.
If this is done incorrectly, it may cause a fire, an electric shock, or an injury from the unit falling, water leaking, etc.
Consult your dealer.
