Other Features

Auto-Restart
If the unit loses power, it will automatically restart with the prior settings once power has been restored.
Louver Angle Memory
When turning on your unit, the louver will automatically resume its former angle.
Refrigerant Leakage Detection
The indoor unit will automatically display “EL0C” when it detects refrigerant leakage.
Active Clean Function
The Active Clean Technology washes away dust, mold, and grease that may cause odors when it adheres to the heat exchanger by automatically freezing and then rapidly thawing the frost. A “pi-pi” sound will be heard. The Active clean operation is used to produce more condensed water to improve the cleaning eff ect, and the cold air will blow out. After cleaning, the internal wind wheel then keeps operating with hot air to blow-dry the evaporator, thus preventing the growth of mold and keeping the inside clean. — When this function is turned on, the indoor unit display window appears “CL ” , after 20 to 45 minutes, the unit will turn off automatically and cancel Active Clean function.
ECO Intelligent (Single Zone Only)
The system is controlled intelligently under Intelligent eye mode. It can detect the people’s activities in the room. In cooling/Heating/Auto mode, when you are away for 30 minutes, the unit will automatically lower the frequency to save energy. And the unit will automatically start and resume operation if sensing human activity again.
Humidity Control (Single Zone Only)
The unit is able to increase the comfortable level by lowering humidity in your home. The unit offers a better temperature and humidity control solution in the dry mode, the room temperature can be maintained accurately as set temperature while the moisture is being removed.
The Intelligent Eye and Humidity Control feature may not be available in all configurations.
Sleep Operation
The SLEEP function is used to decrease energy use while you sleep (and don’t need the same temperature settings to stay comfortable). This function can only be activated via remote control. And the Sleep function is not available in FAN or DRY mode.
Press the SLEEP button when you are ready to go to sleep. When in COOL mode, the unit will increase the temperature by 1°C (2°F) after 1 hour, and will increase an additional 1°C (2°F) after another hour. When in HEAT mode, the unit will decrease the temperature by 1°C (2°F) after 1 hour, and will decrease an additional 1°C (2°F) after another hour.

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 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.
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 ﬂuctuates again.
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 & contraction of the unit’s plastic parts.
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.
Both the indoor unit and outdoor unit make noises| 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 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 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:
