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 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 interuption. 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.
Clean Air Function (optional):
Improving the quality of indoor air is one of the purposes of an air conditioner. Thsi unit is equiped
with an ionizer or plasma dust collector, depending on the model. The ionizers generates anions to
circulate natural healthy air. The plasma dust collector generates a high voltage ionization zone. Most
dust, smoke, and pollen particles are captured by the electrostatic filter.
Anti-Mildew Function (optional):
When the unit is turned off, in COOl, DRY, AUTO (cool) modes, it will continue to run for about 10
minutes with a low fan airflow. This aids in drying up any condensation inside the unit to prevent
mildew growth. Do not restart the air conditioner until the unit is completely off.
Optimal Operation:
In the event of a power interuption such as a blackout, the air conditioner will stop. It will then restart
automatically and resume the previous operation when the power supply returns.
