Check the timer settings.
A power failure has occurred during operation.
• Wait for the power to come back. If you have the Auto Restart
function enabled, your unit will resume its last operation several
minutes after power is restored.
The Auto Clean function is being operated.
• Allow the Auto Clean function to continue since it removes any
remaining moisture inside the indoor unit. If you do not want this
feature, you can turn the unit off.
The cooled air from the air conditioner makes mist.
• When the room temperature decreases, this phenomenon will
disappear.
In the heating operations, condensed water drops from the
heat exchanger.
• This symptom requires installing a drain hose under the base pan.
Contact the installer.
A clicking sound can be heard when the unit starts or stops
due to movement of the reversing valve.
Creaking sound: The plastic parts of the indoor unit creak
when they shrink or expand due to sudden temperature
changes.
Flowing or Blowing sound: This is the flow of refrigerant
through the air conditioner.
• These are normal symptoms. The noise will stop.
