When air conditioner is not going to be used for a long time. 1 Operate the air conditioner on Air circulation mode (Refer to page 21) for 2 to 3 hours. • This will dry out the internal mechanisms. 2 Turn off the circuit breaker, and disconnect the power cable. CAUTION: Turn off the circuit breaker When the air conditioner is to be used again. 1 Clean the air filter and install it in the indoor unit. (Refer to page 23~25 for cleaning filters.) 2 Check that the air inlet and outlet of the indoor/outdoor unit are not blocked. when the air conditioner is not going to be used for a long time. Dirt may collect and may cause a fire. 3 Remove the batteries from the Remote Controller. 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 if 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. 26 Multi Type Air Conditioner Maintenance and Service Troubleshooting Check the following points before requesting repairs or service.... If the fault persists, please contact your dealer or service center.
