The unit should not be installed, relocated, disassembled, altered,
or repaired by the user.
An improperly handled air conditioner may cause re, electric shock,
injury, or water leakage, etc. Consult your dealer.
If the power supply cord is damaged, it must be replaced by the manu-
facturer or its service agent in order to avoid a hazard.
When installing, relocating, or servicing the unit, make sure that
no substance other than the specifi ed refrigerant (R32) enters the
refrigerant circuit.
Any presence of foreign substance such as air can cause abnormal
pressure rise and may result in explosion or injury.
The use of any refrigerant other than that specifi ed for the system will cause
mechanical failure, system malfunction, or unit breakdown. In the worst case,
this could lead to a serious impediment to securing product safety.
This appliance is not intended for use by persons (including children)
with reduced physical, sensory or mental capabilities, or lack of ex-
perience and knowledge, unless they have been given supervision or
instruction concerning use of the appliance by a person responsible
for their safety.
Children should be supervised to ensure that they do not play with
the appliance.
Do not insert your nger, a stick, or other objects into the air inlet
or outlet.
This may cause injury, since the fan inside rotates at high speeds during
operation.
In case of an abnormal condition (such as a burning smell), stop the
air conditioner and disconnect the power plug or turn the breaker OFF.
A continued operation in the abnormal state may cause a malfunction,
re, or electric shock. In this case, consult your dealer.
When the air conditioner does not cool or heat, there is a possibility of refrig-
erant leakage. If any refrigerant leakage is found, stop operations and venti-
late the room well and consult your dealer immediately. If a repair involves
recharging the unit with refrigerant, ask the service technician for details.
The refrigerant used in the air conditioner is not harmful. Normally, it
does not leak. However, if refrigerant leaks and comes in contact with
re or heating part of such a fan heater, kerosene heater, or cooking
stove, it will create harmful gas and there is risk of fi re.
The user should never attempt to wash the inside of the indoor unit.
Should the inside of the unit require cleaning, contact your dealer.
Unsuitable detergent may cause damage to plastic material inside
the unit, which may result in water leakage. Should detergent come in
contact with electrical parts or the motor, it will result in a malfunction,
smoke, or fi re.
The appliance shall be stored in a room without continuously operating
ignition sources (for example: open ames, an operating gas appliance
or an operating electric heater).
Be aware that refrigerants may not contain an odour.
Do not use means to accelerate the defrosting process or to clean the
appliance, other than those recommended by the manufacturer.
Do not pierce or burn.
The indoor unit must be installed in rooms which exceed the fl oor
space specifi ed. Please consult your dealer.

of a lightning strike.
The unit may be damaged if lightning strikes.
After the air conditioner is used for several seasons, perform inspec-
tion and maintenance in addition to normal cleaning.
Dirt or dust in the unit may create an unpleasant odor, contribute to
growth of fungi, such as mold, or clog the drain passage, and cause
water to leak from the indoor unit. Consult your dealer for inspection
and maintenance, which require specialized knowledge and skills.
Do not operate switches with wet hands.
This may cause electric shock.
Do not clean the air conditioner with water or place an object that
contains water, such as a fl ower vase, on it.
This may cause fi re or electric shock.
Do not step on or place any object on the outdoor unit.
This may cause injury if you or the object falls down.
IMPORTANT
Dirty lters cause condensation in the air conditioner which will contribute to the
growth of fungi such as mold. It is therefore recommended to clean air fi lters every
2 weeks.
Before starting the operation, ensure that the horizontal vanes are in the closed posi-
tion. If operation starts when the horizontal vanes are in the open position, they may
not return to the correct position.

● 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.
Symptom Explanation & Check points
Indoor Unit
The unit cannot be operated. • Is the breaker turned on?
• Is the power supply plug connected?
• Is the ON timer set? Page 12
The horizontal vane does not
move. • 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 hori-
zontal vanes’ operation resumes. The same is
true in the emergency cooling operation.
The unit cannot be operated for
about 3 minutes when restarted. This protects the unit according to instructions
from the microprocessor. Please wait.
Mist is discharged from the air
outlet of the indoor unit.
The cool air from the unit rapidly cools moisture
in the air inside the room, and it turns into mist.
The swing operation of the HORI-
ZONTAL VANE is suspended for a
while, then restarted.
• This is for the swing operation of the HORIZON-
TAL VANE to be performed normally.
When SWING is selected in
COOL/DRY/FAN mode, the
lower horizontal vane does not
move.
• It is normal that the lower horizontal vane does
not move when SWING is selected in COOL/
DRY/FAN mode.
The airfl ow direction changes
during operation.
The direction of the horizontal
vane cannot be adjusted with
the remote controller.
When the unit is operated in COOL or DRY
mode, if the operation continues with air blow-
ing 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 tem-
perature is too low or when defrosting is being
done, the horizontal vane is automatically set
to horizontal position.
The operation stops for about
10 minutes in the heating
operation.
• 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.)
The unit starts operation by
itself when the main power is
turned on, but hasn’t received
sign from the remote controller.
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 control-
ler just before the shutoff of the main power.
Refer to “Auto restart function”. Page 14
The two horizontal vanes touch
each other. The horizontal
vanes are in an abnormal posi-
tion. The horizontal vanes do
not return to the correct “close
position”.
Perform one of the following:
Turn off and on the breaker. Make sure the hori-
zontal vanes move to the correct “close position”.
• Start and stop the emergency cooling operation
and make sure the horizontal vanes move to the
correct “close position”.
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.
• When the room temperature deviates from the
set temperature, the indoor fan starts running
according to the settings on the remote control-
ler.
The indoor unit discolors over
time. • 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.
The operation indicator lamp is
dim. The unit does not beep. • Is the NIGHT mode set?
Multi system
The indoor unit which is not
operating becomes warm and a
sound, similar to water fl owing,
is heard from the unit.
• A small amount of refrigerant continues to ow
into the indoor unit even though it is not operat-
ing.
When heating operation is
selected, operation does not
start right away.
• 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 com-
pressor is running. Even if the
fan starts to rotate, it stops soon.
When the outside temperature is low during
cooling operation, the fan operates intermittently
to maintain suffi cient cooling capacity.
Water leaks from the outdoor
unit. • 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.
White smoke is discharged from
the outdoor unit. • In the heating operation, vapor generated by the
defrosting operation looks like white smoke.
Symptom Explanation & Check points
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 5
Is the polarity (+, -) of the batteries correct?
Page 5
• Are any buttons on the remote controller of other
electric appliances being pressed?
The operation mode cannot be
changed. • Disable the OPERATION LOCK.
Does not cool or heat
The room cannot be cooled or
heated suffi ciently. • Is the temperature setting appropriate?
Page 7
• Is the fan setting appropriate? Please change
fan speed to High or Super High. Page 8
• Are the fi lters clean? Page 15
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?
• It may take a certain time to reach the setting
temperature or may not reach that depending on
the size of the room, the ambient temperature,
and the like.
• Is the NIGHT mode set?
The room cannot be cooled
suffi ciently. • When a ventilation fan or a gas cooker is used
in a room, the cooling load increases, resulting
in an insuffi cient cooling effect.
• When the outside temperature is high, the cooling
effect may not be suffi cient.
The room cannot be heated
suffi ciently. • When the outside temperature is low, the heating
effect may not be suffi cient.
Air does not blow out soon in
the heating operation. • Please wait as the unit is preparing to blow out
warm air.
Airfl ow
The air from the indoor unit
smells strange. • Are the fi lters clean? Page 15
• 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 it out
with the air.
Sound
Cracking sound is heard. • This sound is generated by the expansion/con-
traction of the front panel, etc. due to change in
temperature.
“Burbling” sound is heard. This sound is heard when the outside air is
absorbed from the drain hose by turning on the
range hood or the ventilation fan, making water
owing 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.
Mechanical sound is heard
from the indoor unit. This is the switching sound in turning on/off the
fan or the compressor.
The sound of water fl owing is
heard. • This is the sound of refrigerant or condensed
water fl owing in the unit.
Hissing sound is sometimes
heard. • This is the sound when the ow of refrigerant
inside the unit is changed.
Timer
Weekly timer does not operate
according to settings. • Is the ON/OFF timer set? Page 12
• Transmit the setting information of the weekly
timer to the indoor unit again. When the infor-
mation is successfully received, a long beep will
sound from the indoor unit. If information fails to
be received, 3 short beeps will be heard. Ensure
information is successfully received. Page 13
• When a power failure occurs and the main power
turns off, the indoor unit built-in clock will be
incorrect. As a result, the weekly timer may not
work normally.
Be sure to place the remote controller where
the signal can be received by the indoor unit.
