Features
Default Setting
When the air conditioner restarts after a power failure, it
will default to the factory settings (AUTO mode, AUTO fan,
24°C (76°F)). This may cause inconsistencies on the remote
control and unit panel. Use your remote control to update
the status.
Auto-Restart (some models)
In case of power failure, the system will immediately stop.
When power returns, the Operation light on the indoor
unit will flash. To restart the unit, press the ON/OFF button
on the remote control. If the system has an auto restart
function, the unit will restart using the same settings.
Energy Saving Tips
• DO NOT set the unit to excessive temperature levels.
• While cooling, close the curtains to avoid direct sunlight.
• Doors and windows should be kept closed to keep cool or warm air in the room.
• DO NOT place objects near the air inlet and outlet of the unit. This will reduce the efficiency of the unit.
• Set a timer and use the built-in SLEEP/ECONOMY mode if applicable.
• If you don't plan to use the unit for a long time, remove the batteries from the remote control.
• Clean the air filter every two weeks. A dirty filter can reduce cooling or heating efficiency.
• Adjust louvers properly and avoid direct airflow.
Closing the curtains while heating also
helps keep the heat in

Louver Angle Memory Function (Optional)
Some models are designed with a louver angle memory
function. When the unit restarts after a power failure, the
angle of the horizontal louvers will automatically return to
the previous position. The angle of the horizontal louver
should not be set too small as condensation may form and
drip into the machine. To reset the louver, press the manual
button, which will reset the horizontal louver settings.
Refrigerant Leak Detection System (some models)
In the event of a refrigerant leak, the LCD screen will
display "EC" and the LED indicator light will flash.
Doors and windows should be kept
closed
