4. Thermostat Control Knob
Set the thermostat control knob to your desired setting. (Usually 6 ~ 7 is recommended.)
If the room temperature is not as desired after a reasonable period, turn the thermostat
control knob clockwise to cool the room more or anticlockwise to cool the room less.
• When the thermostat control knob is set to 10, moisture may freeze onto the
evaporator fins and prevent effective cooling. If this happens, turn the main control
knob to HIGH FAN, and the thermostat control knob anticlockwise. This will quickly
defrost the evaporator fins so that normal cooling can be resumed.

5. Air Swing Switch
(Airflow direction adjustment Side-to-Side)
To obtain a fix airflow direction, set the air swing switch to “ON” for the vanes to swing
from side to side until the desired flow direction is reached, then switch it to “OFF”.
For continuous side-to-side air circulation, set the air swing switch to “ON”.
