The two horizontal vanes touch each other. The horizontal vanes are in an abnormal position. The horizontal vanes do not return to the correct "close position".	Perform one of the following:• Turn off and on the breaker. Make sure the horizontal vanes move to the correct "close position".• Start and stop the emergency cooling operation and make sure the horizontal vanes move to the correct "close position".
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 deviates from the set temperature, 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 some factors such as ultraviolet light and temperature, this has no effect on the product functions.
Multi system
The indoor unit which is not operating becomes warm and a sound, similar to water flow-ing, is heard from the unit.	• A small amount of refrigerant control 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
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 Ic cooling operation, the fan operates intermittently to maintain sufficient cooling capacity.
Water leaks from the outdoor unit.	• During COOL and DRY operations, pipe or pin 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 make 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 defrosting operation looks like white smoke.

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.the	This sound is heard when the out 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 out blows into the drain hose in case 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 inside the unit is changed.
