be abnormal, in this case unplug from the power supply and re-plug after
2-3 seconds.
• 3 minute delay will occur when changing mode during operation.
• This smell may come from another source such as furniture, cigarette
etc, which is sucked in the unit and blown out with the air.
• Normal behaviour caused by the flow of refrigerant in the air
conditioner.
• Defrosting sound in heating mode.
• The sound may be generated by the expansion or contraction of the
front panel due to temperature changes.
• Mist is present in the room with low temperature? Normal behaviour
due to cool air discharged from indoor unit during COOLING or DRY
