Do not overcool the room.
This is not good for the health and wastes electricity.
Keep blinds or curtains closed.
Do not let direct sunshine enter the room when the air conditioner is in operation.
Keep the room temperature uniform.
Adjust the vertical and horizontal airflow direction to ensure a uniform temperature in the room.
Make sure that the doors and windows are shut thight.
Avoid opening doors and windows as much as possible to keep the cool air in the room.
Clean the air filter regularly.
Blockages in the air filter reduce the airflow and lower cooling and dehumidifying effects. Clean at least once every two weeks.
Ventilate the room occasionally.
Since windows are kept closed, it is a good idea to open them and ventilate the room now and ten.
Use high fan speed for effective and fast cooling.
The unit gives its rated cooling capacity when the fan speed is high.
Don't touch this plasma filter within 10 seconds after opening the inlet grille, it may cause an electric shock.
Type 2: Pull the front panel from both sides as shown.
Then pull the filter tab slightly forward to remove the filter. After removing the air filter remove the plasma and triple deodorizer filter by slightly pulling forward.
