The indoor unit emits

white mist

In humid regions, a large temperature diﬀerence between the room’s 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

A squeaking sound is heard when the system is OFF or in COOL mode. The noise is also heard

when the drain pump (optional) is in operation.

Both the indoor unit and

outdoor unit make noises

A low hissing sound may occur during operation. This is normal and is caused by refrigerant gas

ﬂowing through both the indoor and outdoor units.

A low hissing sound may be heard 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 outdoor unit makes

noises The unit will make diﬀerent sounds based on its current operating mode.

Dust is emitted from

either the indoor or

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.
