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.
Troubleshooting

◄ Page 15 ►
Issue Possible Causes
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.
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.
The unit emits a bad
odor
The unit may absorb odors from the environment (such as furniture,
cooking, cigarettes, etc.) which will be emitted during operations.
The unit’s filters 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.
