Common Issues
The following problems are not a malfunction and in most situations will not require repairs.
Issue Possible Causes
Unit does not turn on
when pressing ON/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 continue operating when the temperature uctuates
again.
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 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.
Both the indoor unit
and outdoor unit make
noises
Low hissing sound during operation: This is normal and is caused by refrigerant
gas owing 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.

odor
The unit may absorb odors from the environment (such as furniture, cooking,
cigarettes, etc.) which will be emitted during operations.
The unit’s lters have become moldy and should be cleaned.
The fan of the outdoor unit
does not operate
During operation, the fan speed is controlled to optimize product operation.
