When air conditioner is not going to be used for a long time. Operate the air conditioner on Air circulation mode (Refer to page 14) for 2 to 3 hours. · This will dry out the internal mechanisms. When the air conditioner is to be used again. Clean the air filter and install it in the indoor unit. (Refer to page 16 for cleaning filters.) Operating Instructions Turn off the circuit breaker, and disconnect the plug. CAUTION 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. Remove the batteries from the remote control. Check that the air inlet and outlet of the indoor/outdoor unit are not blocked. Care and Maintenance Operation Tips Do not overcool the room. 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. This is not good for the health and wastes electricity. Troubleshooting Tips Make sure that the doors and windows are shut tight. Avoid opening doors and windows as much as possible to keep the cool air in the room. Clean the air filter regularly. Ventilate the room occasionally. Since windows are kept closed, it is a good idea to open them and ventilate the room now and then. Blockages in the air filter reduce the airflow and lower cooling and dehumidifying effects. Clean at least once every two weeks. 18 Before you call for service... ? Troubleshooting Tips! Save time and money! ENGLISH Check the following points before requesting repairs or service.... If the fault persists, please contact your dealer or service center. Case The air conditioner does not operate. Explanation · Have you made a mistake in timer operation? · Has the fuse blown or has the circuit breaker been tripped? · Check that this is not a damp smell exuded by the walls, carpet, furniture, or cloth items in the room. · Condensation occurs when the airflow from the air conditioner cools the warm room air. See page 13 - The room has a peculiar odor. - It seems that condensation is leaking from the air conditioner. Air conditioner does not operate for about 3 minutes when restarted. Does not cool or heat effectively. - · This is the protector of the mechanism. · Wait about three minutes and operation will begin. · Is the air filter dirty? See air filter cleaning instructions. · Has the temperature been set incorrectly? · Are the indoor unit's air inlet or outlet vents obstructed? · For a noise that sounds like water flowing. -This is the sound of freon flowing inside the air conditioner unit. · For a noise that sounds like the compressed air releasing into atmosphere. -This is the sound of the dehumidifying water being processed inside the air conditioning unit. · Are the batteries depleted? · Are the batteries inserted in the opposite (+) and (-) directions? · This sound is generated by the expansion/constriction of the front panel, etc. due to changes of temperature. - 16 7, 10 - The air conditioner operation is noisy. - Remote control display is faint, or no display at all. 4 Crack sound is heard. - NOTE WATER RESISTANT: The outdoor side of this appliance is WATER RESISTANT. The indoor side is not water resistant and should not be exposed to excess water. 19 P/No.: 3828A20083U Printed in Korea
