If clogged with dirt or soot, the heat exchanger and panel vents may be professionally steam cleaned. NOTE Dirty or clogged coils will reduce the operating efficiency of the system and cause higher operating costs. Operation Tips! 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. Self-Diagnosis Function This unit has an inbuilt error diagnosis capability.
