Operating Instructions

Special Functions
Refrigerant Leakage Detection (optional):
When refrigerant leakage is detected, the indoor unit will display “EC” code or flash LEDs, depending
on the model.
Louver Angle Memory Function (optional):
Within the scope of the safe operation angle, the horizontal louver angle is memorized and will return
to the position last selected by the user. If it exceeds the safe operation angle, it will default within
the safe operation range. However, it will not return to safe operation angle when Turbo mode is set
or the unit is in manual control or after a power interruption. Subsequently, it is strongly
recommended that the horizontal louver angle not be set too small, to avoid possible condensation
leakage.
Self Clean Function:
Airborne bacteria can grow in the moisture on indoor heat exchangers. Regular drying of the
exchanger prevents growth. By simply pressing the SELF CLEAN button on the remote, the system
will automatically manage the process. This cleaning function can be performed as often as desired.
· The unit will operate in the following sequence:
FAN mode on LOW then HEAT mode with LOW fan speed then FAN mode on LOW then STOP
operation and turn off.
· This function can only be activated in COOL or DRY modes
· It is recommended to allow the unit to run in COOL mode for at least 30 minutes before
activation.
· Pressing the SELF CLEAN button again will cancel the operation.
Optimal Operation:
In the event of a power interruption such as a blackout, the air conditioner will stop. It will then
restart automatically and resume the previous operation when the power supply returns.
WIFI Control Function
Connect the wireless control module via the USB port in the back of the front cover of the indoor unit
for the unit to be controlled by remote control and/or smartphone app.
Mute Function (optional)
Press the LED button on the remote to turn off the LED display and silence the buzzer of the indoor
unit, creating a quiet comfortable environment.
