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? Page 7
The horizontal vane does not move.	·Is the horizontal vane installed correctly? ·Is the fan guard deformed?
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 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 flow 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 blowing down for around 1 hour, the direction of the air flow is automatically set to position (1) to prevent water from condensing and dripping. ·In the heating operation, if the air flow temperature is too low or when defrosting is being done, the horizontal vane is automatically set to horizontal 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 operated 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 controller just before the shut off of the main power. Refer to "Auto restart function" page 5.
Multi system
The indoor unit which is not operating becomes warm and a sound, similar to water flowing, is heard from the unit.	·A small amount of refrigerant continues to flow into the indoor unit even though it is not operating.
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
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 water frozen on the outdoor unit melt and drip down.
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 cooling operation, the fan operates intermittently to maintain sufficient cooling capacity.
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 4 • Is the polarity (+,-) of the batteries correct? Page 4 • Are any buttons on the remote controller of other electric appliances being pressed?
Does not cool or heat
The room cannot be cooled or heated sufficiently.	• Is the temperature setting appropriate? Page 5 • Is the fan setting appropriate? Please change fan speed to higher setting. Page 6 • Are the filters clean? Page 8 • 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?
The room cannot be cooled sufficiently.	• 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.
The room cannot be heated sufficiently.	• When the outside temperature is low, the heating effect may not be sufficient.
Air does not blow out soon in the heating operation.	• Please wait as the unit is preparing to blow out warm air.
Airflow
The air from the indoor unit smells strange.	• Are the filters clean? Page 8 • 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.
The sound as burbling 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.
Hissing sound is sometimes heard.	• This is the sound when the flow of refrigerant inside the unit is switched.

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.
