Mist is discharged from the air outlet of the indoor unit.
The swing operation of the HORIZONTAL VANE is suspended for a while, then restarted.
The airfl ow direction changes during operation. The direction of the horizontal vane cannot be adjusted with the remote controller.
The operation stops for about 10 minutes in the heating operation.
The unit starts operation by itself when the main power is turned on, but isn’t received sign from the remote control­ler.
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.
The indoor unit discolors over time.
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.
Water leaks from the outdoor unit.
White smoke is discharged from the outdoor unit.
• Is the breaker turned on?
• Is the power supply plug connected?
• Is the ON timer set? Page 8
• Are the horizontal vanes installed correctly?
Page 11
• Are the horizontal vane and the vertical vane installed correctly? Page 11
• Is the fan guard deformed?
This protects the unit according to instruc­tions from the microprocessor. Please wait.
• The cool air from the unit rapidly cools mois­ture in the air inside the room, and it turns into mist.
• This is for the swing operation of the HORI­ZONTAL VANE to be performed normally.
• 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 airfl ow is automatically set to horizon­tal position to prevent water from condensing and dripping.
• In the heating operation, if the airfl ow tem­perature is too low or when defrosting is be­ing done, the horizontal vane is automatically set to horizontal position.
• 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.)
• 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 .
• When the room temperature rises and the outdoor unit turns on, the indoor fan starts running according to the settings on the remote controller.
• Although plastic turns yellow due to the infl u­ence of some factors such as ultraviolet light and temperature, this has no effect on the product functions.
• When the outside temperature is low dur­ing cooling operation, the fan operates intermittently to maintain suffi cient cooling capacity.
• 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.
In the heating operation, vapor generated by the defrosting operation looks like white smoke.

• 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 insuffi cient cooling effect.
• When the outside temperature is high, the cooling effect may not be suffi cient.
• When the outside temperature is low, the heating effect may not be suffi cient.
• Please wait as the unit is preparing to blow out warm air.
• Do you have an arrangement with your elec­tric company for Demand Response?

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.
• This is the switching sound in turning off/on the fan or the compressor.
• This is the sound of refrigerant or condensed water fl owing in the unit.
• This is the sound when the fl ow of refrigerant inside the unit is changed.
• 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.
