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. Check that the air inlet and outlet of the indoor/outdoor unit are not blocked. Check that the ground wire is connected correctly. It may be connected to the indoor unit side. 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. 10 Indoor Unit ENGLISH Maintenance and Service Before you call for service... ?
