several minutes after power is restored.

operating even when

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.

discharging mist.
The cooled air from the air
conditioner makes mist.
When the room temperature decreases,
