Explanation & Check points
• Are the batteries exhausted?
• Is the polarity (+, -) of the batteries correct?
• Did you press the reset button after replacing the
batteries?
• Is the setting of multiple indoor units' installation
the same as before replacing the batteries?
• 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.
• Is the temperature setting appropriate?
• Is the fan setting appropriate? Please change
fan speed to High or Super High.
• Is the air outlet selection is set to 1 flow? Set it
to 2 flow.
• 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?
• If there is an obstacle above the indoor unit,
the room may not be cooled or warmed due to
insufficient airflow.
• If something is blocking the airflow from the
downward airflow flap during 2 flow (upward and
downward airflow), the airflow will be weakened
and the room temperature will not be detected
correctly.
Do not place any obstacles near the unit as it will
become difficult to heat or cool the entire room.
If you cannot move obstacles, set (
the remote controller to 1 flow operation (upward
airflow).
• 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.
• 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 cool-
ing effect may not be sufficient.
• When the outside temperature is low, the heating
effect may not be sufficient.
• Please wait as the unit is preparing to blow out
warm air.
• 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 it out
with the air.
Symptom
Sound
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.
The sound of motor and swirl-
ing sound is heard from the
indoor unit.
Heating operation stops and
the sound is heard.
Timer
Weekly timer does not operate
according to settings.
) on
The unit starts/stops the opera-
tion by itself.
Dirt
The ceiling and wall around the
indoor unit get dirty.
Other
The aluminum fin on the edge
of the heat exchanger is dis-
colored as if it is burnt.
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/off type
fluorescent lamp (inverter-type fluorescent lamp, etc.) is used.
• Operation of the air conditioner interferes with radio or TV reception. An amplifier
may be required for the affected device.
• When an abnormal sound is heard.
• When any refrigerant leakage is found.
Explanation & Check points
• This sound is generated by the expansion/
contraction of the panel, 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, making 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 switched.
• 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.)
• 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 flowing, Hissing
sound and Whistling sound are heard.
• Is the on/off timer set?
• 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.
• 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.
• Is the weekly timer set?
• Please clean the periphery of the air conditioner
frequently.
• Stains can be prevented by reducing the amount
of air directed toward the ceiling and the walls
and by adjusting the vertical wind direction.
• This is the coating resin discolored due to weld-
ing heat when the heat exchanger was being
produced.
• The operation of the air conditioner is not the
cause of the discoloration.
It affects neither the performance of the heat
exchanger nor the use of the air conditioner.
