Other Features
- Auto-Restart(some units): If the unit loses power, it will automatically restart with the prior settings once power has been restored.
- Anti-mildew (some units): When turning off the unit from COOL, AUTO (COOL), or DRY modes, the air conditioner will continue operate at very low power to dry up condensed water and prevent mildew growth.
- Wireless Control (some units):
- Wireless control allows you to control your air conditioner using your mobile phone and a wireless connection.
- For the USB device access, replacement, maintenance operations must be carried out by professional staff.
- Louver Angle Memory(some units): When turning on your unit, the louver will automatically resume its former angle.
- Active Clean function(some units)
- 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 effect, 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.
- Breeze Away (some units): This feature avoids direct air flow blowing on the body and make you feel indulging in silky coolness.
- Refrigerant Leakage Detection (some units): The indoor unit will automatically display “EL0C”or flash LEDS (model dependent ) when it detects refrigerant leakage.
- 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.
- The sleep feature will stop after 8 hours and the system will keep running with final situation.
NOTE: For multi-split air condtioners, the following functions are not available: Active clean function, Silence feature, Breeze away function, Refrigerant leakage detection function and Eco feature.
Setting Angle of Air Flow
- Setting vertical angle of air flow: While the unit is on, use the SWING/DIRECT button on remote control to set the direction (vertical angle) of airflow. Please refer to the Remote Control Manual for details.
- NOTE ON LOUVER ANGLES:
- When using COOL or DRY mode, do not set louver at too vertical an angle for long periods of time. This can cause water to condense on the louver blade, which will drop on your floor or furnishings.
- When using COOL or HEAT mode, setting the louver at too vertical an angle can reduce the performance of the unit due to restricted air flow.
- Setting horizontal angle of air flow
- The horizontal angle of the airflow must be set manually. Grip the deflector rod (See Fig.B) and manually adjust it to your preferred direction. For some units, the horizontal angle of the airflow can be set by remote control. please refer to the Remote Control Manual.

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 fluctuates 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 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 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 |
