Possible Causes
The Unit has a 3-minute protection feature that prevents the unit from over-
loading. 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 temperature increases, the unit will start operating in the previ-
ously 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 fluctu-
ates 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 moisture 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 refrige-
rant 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 cove-
ring the unit during long periods of inactivity.
The unit may absorb odors from the environment (such as furniture, cook-
ing, cigarettes, etc.) which will be emitted during operations.
The unit's filters have become moldy 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.
