Possible Causes
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 may change its setting to prevent frost from forming on the unit. Once the tempera-
ture 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 continue operating when the temperature fluctuates again.
In humid regions, a large temperature difference between the room's air and the conditioned
air can cause white mist.
When the unit restarts in HEAT mode after defrosting, white mist may be emitted due to mois-
ture generated from the defrosting process.
A rushing air sound may occur when the louver resets its position.
A squeaking sound may occur after running the unit in HEAT mode due to expansion and
contraction of the unit's plastic parts.
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 unit will make different sounds based on its current operating mode.
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.
The unit may absorb odours from the environment (such as furniture, cooking, cigarettes,
etc.) which will be emitted during operations.
The unit's filters have become mouldy and should be cleaned.
During operation, the fan speed is controlled to optimize product operation.
Interference from cell phone towers and remote boosters may cause the unit to malfunction.
In this case, try the following:
• Disconnect the power, then reconnect.
• Press ON/OFF button on remote control to restart operation.
