®OPERATING INSTRUCTIONS ®
Even if these items are checked, when the unit does not recover from the
trouble, stop using the air conditioner and consult your dealer.
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 airflow 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 control-
ler.
The damper opens and
closes automatically.
• Is the breaker turned on?
• Is the power supply plug connected?
• Is the ON timer set?
• Is there anything that block the normal opera-
tion of the damper?
• This protects the unit according to instruc-
tions from the microprocessor. Please
wait.
• The cool air from the unit rapidly cools mois-
ture in the air inside the room, and it turns
into mist.
• This is for the swing operation of the HORI-
ZONTAL VANE to be performed normally.
, When the unit is operated in COOL or DRY
mode, if the operation continues with air
blowing down for 1 hour, the direction of
the airflow is automatically set to position
(1) to prevent water from condensing and
dripping.
• In the heating operation, if the airflow tem-
perature is too low or when defrosting is be-
ing done, the horizontal vane is automatically
set to vertical position.
• The horizontal vane automatically moves
in certain intervals to determine its position,
and then it returns to the set 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 re-
start 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 control-
ler just before the shutoff ofthe main power.
Refer to "Auto restart function" _[_.
• The damper is automatically controlled by
a microcomputer according to the airflow
temperature and operation time of the air
conditioner.

Water leaks from the outdoor
unit.
White smoke is discharged
from the outdoor unit.
The display on the remote
controller does not appear or
it is dim. The indoor unit does
not respond to the remote
control signal.
The room cannot be cooled or
heated sufficiently.
The room cannot be cooled
sufficiently.
The room cannot be heated
sufficiently.
Air does not blow out soon in
the heating operation.
The air from the indoor unit
smells strange.
Cracking sound is heard.
"Burbling" sound is heard.
Mechanical sound is heard
from the indoor unit.
The sound of water flowing
is heard.
Hissing sound is sometimes
heard.
, 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.
o 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.
i• Are the batteries exhausted? I[_
• Is the polarity (+, -) of the batteries correct?
• Are any buttons on the remote controller of
other electric appliances being pressed?
• Is the temperature setting appropriate?
, Is the fan setting appropriate? Please change
fan speed to higher setting.
, Is the air outlet selection switch set to upper
air outlet only? Change to upper and lower air
outlets.
, Is the filter clean?
, Is the fan or heat exchanger of the indoor unit
clean?
, Are there any obstacles blocking the air inlet or
outlet of the indoor or outdoor unit?
• Is a window or door open?
, 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 temperature is high, the
cooling effect may not be sufficient.
• When the outside temperature is low, the heat-
ing effect may not be sufficient.
, Please wait as the unit is preparing to blow out
warm air.
o Is the filter clean?
, Is the fan or heat exchanger of the indoor unit
clean?
, The unit may suck in an odor adhering to the
wall, carpet, furniture, cloth, etc. and blow itout
with the air.
• This sound is generated by the expansion/
contraction of the intake grille, etc. due to
change in temperature.
• This sound is heard when the outside air is
absorbed from the drain hose by turning on
the range hood or the ventilation fan, mak-
ing water flowing in the drain hose to spout
out.
This sound is also heard when the outside air
blows into the drain hose in case the outside
wind is strong.
• This is the switching sound in turning on/off
the fan or the compressor.
, This is the sound of refrigerant or condensed
water flowing in the unit.
• This is the sound when the flow of refrigerant
inside the unit is changed.
