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.)
