- And the unit will automatically start and resume operation if sensing human activity again.
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.
- 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 the final temperature reached.
Setting vertical angle of air flow
- While the unit is on, use the SWING button on remote control to set the direction vertical angle) of airflow. Please refer to the
- Remote Control Manual for details.
- The horizontal angle of the airflow can be set by remote control. please refer to the Remote Control
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.
NOTE:
- According to the relative standards requirement, please sets the vertical air flow louver to its maximum angle under heating capacity test.
Cleaning Your Indoor Unit
Cleaning Your Air Filter
A clogged air filter can reduce the cooling efficiency of your unit, can also make the air flow irregular and too much noisy, so please clean the air filter as often as necessary. Once the abnormal noise of air flow is heard, please clean the air filter immediately.
1. The air filter is on the top of the air conditioner.
2. Hold both side of the top filter in the place marked with “PULL”, then pull it upwards.
3. If your filter has small air freshening filters, unclip them from the larger filter. Clean these air freshening filters with a hand-held vacuum.
4. Clean the large air filter with warm, soapy water. Be sure to use a mild detergent.
- Rinse the filter with fresh water, then shake off excess water.
- Dry it in a cool, dry place, and refrain from exposing it to direct sunlight.
- When dry, re-clip the air freshening filter to the larger filter, then install it back on the indoor unit.
Air Filter Cleaning Reminder
- After 240 hours of use, the display window on the indoor unit will flash “CL.” This is a reminder to clean your filter. After 15 seconds, the unit will revert to its previous display.
- To reset the reminder, press the LED button on your remote control 4 times, or press the
- MANUAL CONTROL button 3 times. If you don’t reset the reminder, the “CL” indicator will flash again when you restart the unit.

- To reset the reminder, press the LED button on your remote control 4 times, or press the
- MANUAL CONTROL button 3 times. If you don’t reset the reminder, the “nF” indicator will flash again when you restart the unit
Troubleshooting
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.
- 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.
