Safety Precautions
Do not turn the breaker o except the case of burning smell,
or when performing maintenance or inspection.
• The refrigerant leakage cannot be detected, and this may
cause a re.
Do not install the unit in a place where smoke, gas, or
chemicals may ll.
• Do not use any gas equipment for propane, butane or
methane, sprays such as bug killer, and paint etc., near by
the indoor unit.
• The refrigerant sensor reacts to it and displays an error. This
may cause the unit not to operate.
(Procedure in case of refrigerant leakage)
If the refrigerant leaks, extinguish a re such as a heater,
and ventilate the room adequately by opening the window.
• Then contact your dealer.
• The indoor unit spreads the refrigerant by fan mode to pre-
vent a re. Do not turn the breaker o during this situation.
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 o.
• 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 refrigerant leakage. If any refrigerant leakage
is found, ventilate the room well and consult your dealer
immediately. Do not turn the breaker o. If a repair involves
recharging the unit with refrigerant, ask the service techni-
cian 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 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 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

Wi-Fi Module Seing Up
When You Think That Trouble
Has Occurred
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?
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.
White smoke is discharged
from the air inlet of the indoor
unit.
• When the heating operation starts after the
defrosting operation, vapor generated from the
condensation on the heat exchanger looks like
white smoke.
The swing operation of the
horizontal vane is suspended
for a while, then restarted.
• This is for the swing operation of the horizontal
vane to be performed normally.
The air ow direction changes
during operation.
The direction of the horizontal
vane/multi-ow vane cannot
be adjusted with the remote
controller.
• In the heating operation, if the air ow tempera-
ture is too low or when defrosting is being done,
the horizontal vane is automatically set to vertical
position. The multi-ow vane is set to the closed
position.
• When the air conditioner is operated in cool mode
or dry mode, if the operation continues with air
blowing horizontally for 1 hour, the direction of
the air ow is automatically set to position (1) to
prevent condensed water from dropping. The
multi-ow vane is set to the closed position.
• The horizontal vane and the multi-ow vane auto-
matically moves in certain intervals to determine
its position, and then it returns to the set position.
The operation is stopped for
about 10 minutes in the heating
operation.
• Defrosting of the outdoor unit is being done.
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, though it isn’t oper-
ated with 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 shuto of the main power.
Refer to “Auto Restart Function”.
Page 14
In cool mode/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 controller.
The multi-ow vane opens and
closes automatically.
• The multi-ow vane is automatically controlled by
a microcomputer according to the air ow tem-
perature and operation time of the air conditioner.
The indoor unit which is not
operating becomes warm and
a sound, similar to water ow-
ing, is heard from the unit.
• A small amount of refrigerant continues to ow
into the indoor unit even though it is not operating.
The indoor unit discolors over
time.
• Although plastic turns yellow due to the inuence
of some factors such as ultraviolet light and
temperature, this has no eect on the product
functions.
The walls around the indoor
unit have smudges.
• It is because the walls get dust in the air due to
air circulation by the air conditioner.
Water leaks from the indoor
unit.
• Does water ow smoothly from the edge of the
drain hose?
Outdoor unit
The fan of the outdoor unit
does not rotate even though
the compressor is running.
Even if the fan starts to rotate,
it stops soon.
• When the outside temperature is low during cool-
ing operation, the fan operates intermittently to
maintain sucient cooling capacity.
Water leaks from the outdoor
unit.
• During cooling operation and dry operation, 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 water frozen 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.
EN-12
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 4
• Is the polarity (+, -) of the batteries correct?
Page 4
• Did you press the reset button after replacing the
batteries?
Page 4
• Is the setting of multiple indoor units’ installation
the same as before replacing the batteries?
Page 4
• Are any buttons on the remote controller of other
electric appliances being pressed?
• The indoor unit may not receive the signal well
depending on the condition in the room. Get
close to the indoor unit and operate the remote
controller.
Does not cool or heat
The room cannot be cooled or
heated suciently.
• Is the temperature setting appropriate?
Page 5
• Is the fan setting appropriate? Please change
fan speed to High or Super High.
Page 6
• Is the air outlet selection is set to 1 ow? Set it
to 2 ow.
Page 6
• Is the lter clean?
Page 9
• 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?
• If there is an obstacle above the indoor unit,
the room may not be cooled or warmed due to
insucient airow.
Page 14
• If something is blocking the airow from the
downward airow ap during 2 ow (upward and
downward airow), the airow will be weakened
and the room temperature will not be detected
correctly.
Do not place any obstacles near the unit as it will
become dicult to heat or cool the entire room.
If you cannot move obstacles, set (
) on
the remote controller to 1 ow operation (upward
airow).
• 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.
The room cannot be cooled
suciently.
• When a ventilation fan or a gas cooker is used
in a room, the cooling load increases, resulting
in an insucient cooling eect.
• When the outside temperature is high, the cool-
ing eect may not be sucient.
The room cannot be heated
suciently.
• When the outside temperature is low, the heating
eect may not be sucient.
Air does not blow out soon in
the heating operation.
• Please wait as the unit is preparing to blow out
warm air.

with the air.
In the following cases, stop using the air conditioner and consult your dealer.
• When water leaks or drips from the indoor unit.
• When the left operation indicator lamp blinks.
• When the breaker trips frequently.
• The remote control signal is not received in a room where an electronic on/o type
uorescent lamp (inverter-type uorescent lamp, etc.) is used.
• Operation of the air conditioner interferes with radio or TV reception. An amplier
may be required for the aected device.
• When an abnormal sound is heard.
• When any refrigerant leakage is found.
Symptom Explanation & Check points
Sound
Cracking sound is heard. • This sound is generated by the expansion/
contraction of the 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/o the
fan or the compressor.
The sound of water owing is
heard.
• This is the sound of refrigerant or condensed
water owing in the unit.
Hissing sound is sometimes
heard.
• This is the sound when the ow of refrigerant
inside the unit is switched.
The sound of motor and swirl-
ing sound is heard from the
indoor unit.
• This is the sound of water condensed during
cooling operation/dry operation being drained
from the indoor unit.
• Sound of water draining may also be heard from
indoor units which are not operating. (The sound
will stop automatically. Please wait.)
Heating operation stops and
the sound is heard.
• The outdoor unit is defrosting.
Heating operation starts after the frost on the
outdoor unit has been removed. This can take
about 2 to 10 minutes.
• Cracking sound, Sound of water owing, Hissing
sound and Whistling sound are heard.
Timer

according to settings.
• Is the on/o timer set? Page 7
• 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 8
• When a power failure occurs and the main power
turns o, 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.
