Operation Tips

Operation for comfort and economy

Do not overcool the room temperature. This is not good for health and wastes electricity.
Keep blind or curtains closed. Do not let sunshine enter the room directly when the air condition is in operation.
Keep the room temp. uniform. Adjust the vertical and horizontal airflow direction to ensure a uniform temperature in the room. Air can’t be discharged to the direction of air-in.
Make sure that the doors and windows are tightly closed. Avoid opening doors and windows frequently to keep air conditioning in the room.
Clean the air filter regularly. Blockages in the air filter reduce dehumidifying effects. Clean the air filter 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 then. When starting the unit, curtains or windows should be closed to prevent the heat/cool leakage.
