Parts And Major
Functions
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.
• 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.
• Adjust louvers properly and avoid direct airflow.
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)

will display “EC” and the LED indicator light will
flash.
