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. 12 When the air conditioner is to be used again. When it is not going to be used for a long time. 1 Operate the air conditioner on Air circulation mode for 2 to 3 hours. Check that the air inlet and outlet of the indoor/outdoor unit are not blocked. ¥ This will dry out the internal parts. 2 Turn off the circuit breaker. Helpful information CAUTION CAUTION The air filters and your electiric bill. 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. Turn off the circuit breaker when the air conditioner is not going to be used for a long time. Dirt may collect and may cause a fire. Operation Tips Do not overcool the room. This is not good for the health and wastes electricity. 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. Keep blinds or curtains closed. Make sure that the doors and windows are shut tight. Do not let direct sunshine enter the room when the air conditioner is in operation. Avoid opening doors and windows as much as possible to keep the cool air in the room. Ventilate the room occasionally. Since windows are kept closed, it is a good idea to open them and ventilate the room now and then. 13 ENGLISH When the air conditioner is not going to be used for a long time.
