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 fowing 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.
Operation
is erratic,
unpredictable,
or unit is
unresponsive
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.
NOTE: If problem persists, contact a local dealer or your nearest customer service center.
Provide them with a detailed description of the unit malfunction as well as your model number.

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 fuctuates 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.
