Page 11
• 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.
• It may take a certain time to reach the setting temperature or
may not reach that depending on the size of the room, the ambi-
ent temperature, and the like.
Symptom
Explanation & Check points
Airflow
The air from the indoor unit smells strange.
• Is the filter clean?
Page 11
• 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/contraction 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 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.
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 flowing is heard.
• This is the sound of refrigerant or condensed water flowing in the
unit.
In the following cases, stop using the air conditioner and consult your dealer.
• When water leaks or drips from the indoor unit.
• When the upper operation indicator lamp blinks.
• When the breaker trips frequently.
• The remote control signal is not received in a room where an electronic OFF/ON 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.
