If the air filters become clogged with dust, the cooling capacity will drop, and 6% of the electricity used to operate the air conditioner will be wasted. Operation Tips Do not overcool the room. Keep blinds or curtains closed. Keep the room temperature uniform. This is not good for the health and wastes electricity. Do not let direct sunshine enter the room when the air conditioner is in operation. Adjust the vertical and horizontal airflow direction to ensure a uniform temperature in the room. Make sure that the doors and windows are shut tight. Clean the air filter regularly. Ventilate the room occasionally. Avoid opening doors and windows as much as possible to keep the cool air in the room. Blockages in the air filter reduce the airflow and lower cooling and dehumidifying effects. Clean at least once every two weeks. Since windows are kept closed, it is a good idea to open them and ventilate the room now and then. Owner's Manual 25
