OFF button�
The unit has a 3 minute protection feature that prevents the unit from
overloading� The unit cannot be restarted within three minutes of
being turned off�
The unit changes from COOL/HEAT mode
to FAN mode�
The unit may change its setting to prevent frost from forming on the
unit� Once the temperature increases, the unit will start operating in
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.
Mist emanating form the indoor unit�
Condensation effect that can occur during cooling operations and is
normal� In humid regions, a large temperature difference between
the room air and the conditioned air can cause white mist�
Both the indoor and outdoor units emit
white mist�
When the unit restarts in HEAT mode after defrosting, white mist may
be emitted due to moisture generated from the defrosting process�
The indoor unit makes noises�
Water flowing noise, This is the sound of refrigerant flowing inside
the indoor unit and is normal�
A rushing air sound may occur when the louvre resets its position�
A squeaking sound may occur after running the unit in HEAT mode
due to expansion and contraction of the units plastic parts�
Both the indoor unit and outdoor unit make
noises�
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�
Squeaking sound: Normal expansion and contraction of plastic and
metal parts caused by temperature changes during operation can
cause squeaking noises�
The outdoor unit makes noises�
The unit will make different sounds based on its current operating
mode�

outdoor unit�
The unit may accumulate dust during extended periods of non-use,
which will be emitted when the unit is turned on� This can be mitigated
by covering the unit during long periods of inactivity�
