Once power returns, reset timer.ENERGY SAVING HINTSClean the air filter every 2 weeks. Regular cleaning of the air filter preserves efficiency. Keeping ventilation set to close keeps cool air in and hor air out. Avoid direct sunlight and heat. For health reason do not overcool your room. Your air conditioner’ s cooling capacity should match your room size.7 CARE AND MAINTENANCEAlways turn off the air conditioner and the main power supply before cleaning the unit. Switch off the power supply if the unit is not going to be used for a long period of time.Clean the cabinet, front grille with mild soap or detergent and lukewarm water. The front intake grille can be easily removed for cleaning purposes (refer to Remove the front intake grille procedures). Gently wash it with water and a sponge. The filter can be easily cleaned using a vacuum cleaner. Vacuum the front of the filter and then wash the rear with water. If it is badly spoiled, wash with a mild household detergent. Do not clean with benzene, thinner, scouring powder or cloth soaked in caustic chemicals. If the unit is extremely dirty, heat transfer is less effecient and the unit may not cool effectively. Contact Shun Hing Electric Service Centre Ltd. for an annual check. (Annual check is not covered by the warranty.) If the air filter becomes clogged with dust, the cooling capacity will drop, and 6% of the electricity used to operate the air conditioner will be wasted.NOTE: Do not dry the front panel or the air filter in direct sunlight. (Exposure to direct sunlight may discolour deform the panel.)PRE-SEASON INSPECTION Is the discharged air cold? After 15 minutes of operation, it is normal for the temperature difference between intake and outlet air to be more than 8°C for cooling. Are the air intake and outlet vanes of the indoor and outdoor side obstructed? Are the remote control batteries weak?RECOMMENDED INSPECTION Usage over several seasons will reduce performance as the unit becomes dirty. A dirty unit may produce foul odours and dust may clog the dehumidifying drainage. Seasonal inspection is recommended in addition to regular cleaning.
