depending on set temperature and room temperature.
The unit will control the room temperature automatically,
according to the temperature point you set.
SLEEP Operation:
When selected, the temperature will increase while cooling
or decrease while heating by 1°C / 2°F per hour for the first
2 hours. Thereafter it keeps this new temperature for 6
hours before SLEEP mode switches off.
DRYING Operation:
The temperature is regulated while dehumidifying by
intermittently switching the cooling or fan-only operation on
and off. The fan speed is set to LOW.

HEATING Operation:
This unit is a heat pump by design. By reversing the air
conditioning process, it absorbs heat from outdoors and
transfers it to the indoor unit. As a result, the operating
performance and efficiency is reduced as the outdoor air
temperature drops. If you feel that the heating
performance is insufficient, it is recommended that you
supplement heating with other appliances.
Optimal Operation:
To achieve optimal performance, please note the following:
· Adjust the airflow direction correctly, so that it is not
towards people or at an extreme angle.
· Adjust the temperature to achieve moderate comfort
levels. An excessively low or high temperature setting
wastes energy.
· Keep windows and doors closed, as this improves
performance.
· Limit energy usage (run time) by using the TIMER
function.
· Do not put any objects near the air inlets / outlets. Doing
so would impair performance and possible shut down
the unit.

· Inspect the air filters periodically, and clean them as
needed.

Operating Instructions
Special Functions
Refrigerant Leakage Detection (optional):
When refrigerant leakage is detected, the indoor unit will display “EC” or “ELOC” 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 returns 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.
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 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.
Wireless Smart 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.
Clean Air Filter Reminder (optional):
After 240 hours of operation, the indoor display window will display and flash “CL” as a reminder to
CLEAN the air filter for more efficient operation. After 15 seconds, the system will revert back to the
previous display again. When the “CL” indicator appears and flashes, please press the LED button on
the remote control 4 times or press the manual control button 3 times to reset the hours. If you don’t
reset the reminder, the “CL” indicator will flash again when you restart the unit.
Replace Air Filter Reminder (optional):
After 2880 hours of operation, the indoor display window will display and flash “nF” as a reminder to
REPLACE the air filter for more efficient operation. After 15 seconds, the system will revert back to
the previous display again. When the “CL” indicator appears and flashes, please press the LED button
on the remote control 4 times or press the manual control button 3 times to reset the hours. If you
don’t reset the reminder, the “nF” indicator will flash again when you restart the unit.
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.
