Maintenance and Service Maintenance and Service CAUTION: Before performing any maintenance, turn off the main power to the system. Indoor Unit Grille, Case, and Remote Control o Turn the system off before cleaning. To clean, wipe with a soft, dry cloth. Do not use bleach or abrasives. NOTICE Supply power must be disconnected before cleaning the indoor unit. o Never use any of the followings: • Water hotter than 40°C Could cause deformation and/or discoloration. • Volatile substances Could damage the surfaces of the air conditioner. Pow d er G a s o li n e Air inlet vent Air outlet vent Air filters (behind front panel) Vertical louver Horizontal louver AIR FILTERS The air filters behind the front grille should be checked and cleaned once in every 2 weeks or more often if neccessary. 1 Lift the front access panel and pull the filter tab slightly forward to remove the filter. 2 Clean the filter with a vacuum cleaner or warm, soapy water. • If dirt is conspicuous, wash with a solution of detergent in lukewarm water. • If hot water (40°C or more) is used, it may be deformed. 3 After washing with water, dry well in the shade. 4 Re-install the air filter. NANO PLASMA FILTER, TRIPLE DEODORIZING FILTER(OPTIONAL) The PLASMA filter behind the air filters should be checked and cleaned once in every 3 months or more often if necessary. 1 After removing the air filters, pull slightly forward to remove the NANO PLASMA filter. 2 Remove dust with vacuum cleaner or air. (You should not try to wash with water). 3 Note the cuts of electric discharge lines. 4 Re-install the NANO PLASMA filter to the TRIPLE DEODORIZING Filter NANO PLASMA Filter original position. 1 After removing the air filters, pull slightly forward to remove the TRIPLE DEODORIZING filter.

(Rear) Air intake vents Piping Drain Hose NOTICE Dirty or clogged coils will reduce the operating efficiency of the system and cause higher operating costs. (Side) Air outlet vents Owner’s Manual 21 ENGLISH 1 Open front panel and remove air Maintenance and Service When the air conditioner is not going to be used for a long time. When air conditioner is not going to be used for a long time. When the air conditioner is to be used again. Operate the air conditioner on mode for 2 to 3 hours. Clean the air filter and install it in the indoor unit. (Refer to page 20 for cleaning filters.) • This will dry out the internal mechanisms. Turn off the circuit breaker, and disconnect the plug. Check that the air inlet and outlet of the indoor/outdoor unit are not blocked. CAUTION 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. 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 as much as possible to keep the cool air in the room. Blockages in the air filter reduces the airflow and lowers the cooling and dehumidifying effects. Clean at least once in every two weeks. Since windows are kept closed, it is a good idea to open them and ventilate the room now and then. 22 Room Air Conditioner Maintenance and Service Troubleshooting Case Explanation See page The air conditioner does not operate. • Have you made a mistake in timer operation? • Has the fuse blown or has the circuit breaker been tripped? 17 - The room has a peculiar odor. • Check that this is not a damp smell exuded by the walls, carpet, furniture, or cloth items in the room. - It seems that condensation is leaking from the air conditioner. • Condensation occurs when the airflow from the air conditioner cools the warm room air. - Air conditioner does not operate for about 3 minutes when restarted. • This is the protector of the mechanism. • Wait about three minutes and operation will begin. - Does not cool or heat effectively. • 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? The air conditioner operation is noisy. 20 9, 13 - • 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. - Remote control display is faint, or no display at all. • Are the batteries depleted? • Are the batteries inserted in the opposite (+) and (-) directions? 7 Crack sound is heard. • This sound is generated by the expansion/constriction of the front panel, etc. due to changes of temperature. - Owner’s Manual 23 ENGLISH Check the following points before requesting repairs or service....
