WHEN YOU THINK THAT TROUBLE HAS OCCURRED

Symptom

Explanation & Checkpoints

Indoor Unit

The unit cannot be operated.

• Is the breaker turned on?

• Is the power supply plug connected?

• Is the ON timer set?

All LED lamps on the indoor unit are blinking.

• Are the horizontal vanes installed correctly?

The horizontal vane does not move.

• Are the horizontal vane and the vertical vane installed correctly? | Page 11

• 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 airflow 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 0.5 to 1 hour, the direction of the airflow is automatically set to horizontal position to prevent water from condensing and dripping.

• In the heating operation, if the airflow temperature 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 isn’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 controller just before the shutoff of the main power. Refer to “Auto restart function” Page 5 .

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 rises and the outdoor unit turns on, the indoor fan starts running according to the settings on the remote controller.

The indoor unit discolors over time.

• Although plastic turns yellow due to the influence of some factors such as ultraviolet light and temperature, this has no effect on the product functions.

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 cooling operation, the fan operates intermittently to maintain sufficient 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.

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 suffi ciently

• Is the temperature setting appropriate? Page 5

• Is the fan setting appropriate? Please change fan speed to High or Super High. Page 6

• Are the fi lters clean? Page 11

• Is the fan or heat exchanger of the indoor unit clean? Page 11

• 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.

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.
Poor cooling or heating performance.• Do you have an arrangement with your electric company for Demand Response?
Airflow
The air from the indoor unit smells strange.

• Are the fi lters clean? Page 11

• Is the fan or heat exchanger of the indoor unit clean? Page 11

• 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 fl 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 off/on the fan or the compressor.
The sound of water flowing 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 fl ow of refrigerant inside the unit is changed.
Timer
Weekly timer does not operate according to settings.

• Is the ON/OFF timer set? Page 8, 9

• Transmit the setting information of the weekly timer to the indoor unit again. When the information 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 9

• 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. Page 3

The unit starts/stops the operation by itself.• Is the weekly timer set? Page 9

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 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.

WHEN THE AIR CONDITIONER IS NOT GOING TO BE USED FOR A LONG TIME
