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 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 fluctuates again.
When the unit restarts in HEAT mode after defrosting, white mist may
be emitted due to moisture generated during the defrosting process.
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 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.
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.
