from overloading� The unit cannot be restarted within three minutes
of being turned off.

the previously selected mode again�
The set temperature has been reached, at which point the unit
turns off the compressor. The unit will resume operation when the
temperature fluctuates again.

may be emitted due to moisture generated from the defrosting
process�
Water flowing noise, This is the sound of refrigerant flowing inside
the indoor unit and is normal�
Low hissing sound during operation: This is normal and is caused
by refrigerant gas flowing through both indoor and outdoor units.
Low hissing sound when the system starts, has just stopped
running, or is defrosting: This noise is normal and is caused by the
refrigerant gas stopping or changing direction�
The unit will make different sounds based on its current operating
mode�

furniture, cooking, cigarettes, etc�), which may be emitted during
operation�
