Operation Tips Do not overcool the room. Keep blinds or curtains closed. 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. 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 tight. Clean the air filter regularly. 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. Ventilate the room occasionally. Since windows are kept closed, it is a good idea to open them and ventilate the room now and then. Ownerʼs Manual 11
