The cooled air from the appliance makes mist.

A clicking sound can be heard when the appliance 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.
• Noise is normal during or after operation. It is not a sign of malfunction.
Flowing sound: This is the flow of refrigerant through the appliance.

into the atmosphere.
This is the sound of the dehumidifying water being processed inside the
air conditioning unit.
• These are normal symptoms. The noise will stop.
This sound is generated by the expansion or constriction of the front
panel, etc. due to changes of temperature.
• These are normal symptoms. The noise will stop.
Odours (such as cigarette smoke) may be absorbed into the indoor unit
and discharged with airflow.
• If the smell does not disappear, you need to wash the filter. If this does not
work, contact the service centre to clean your heat exchanger.
Check that this is not a damp smell exuded by the walls, carpet,
furniture or cloth items in the room.
