TYPE : CEILING CONCEALED DUCT MODEL : AUSTRALIA HIGH STATIC DUCT www.lg.com P/NO : MFL41032507 2 TIPS FOR SAVING ENERGY ENGLISH TIPS FOR SAVING ENERGY Here are some tips that will help you minimize the power consumption when you use the air conditioner. You can use your air conditioner more efficiently by referring to the instructions below: • Do not cool excessively indoors. This may be harmful for your health and may consume more electricity. • Block sunlight with blinds or curtains while you are operating the air conditioner. • Keep doors or windows closed tightly while you are operating the air conditioner. • Adjust the direction of the air flow vertically or horizontally to circulate indoor air. • Speed up the fan to cool or warm indoor air quickly, in a short period of time. • Open windows regularly for ventilation as the indoor air quality may deteriorate if the air conditioner is used for many hours. • Clean the air filter once every 2 weeks. Dust and impurities collected in the air filter may block the air flow or weaken the cooling / dehumidifying functions.

Never try to repair by yourself or restart the system in such cases. - Main power cord is too hot or damaged. - Error code is generated by self diagnosis. - Water leaks from indoor unit. - Any switch, breaker (safety, earth) or fuse fails to work properly User must carry routine checkup & cleaning to avoid unit’s poor performance. In case of special situation, the job must be carried out by the only service person. Air outlet vent Two wired remote controller - All wired remote controllers are displayed on identical information. - Last used wired romote controller has priority on product's movement. MAINTENANCE AND SERVICE 13 Do not overcool the room. This is not good for the health and wastes electricity. Keep blinds or curtains closed. Do not let direct sunshine enter the room when the air conditioner is in cooling operation. Make sure that the doors and windows are shut tight. Avoid opening doors and windows as much as possible to keep the air conditioned 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 from time to time. Filter The units shipped without a filter and is the responsibility of the installer to secure a filter in the return air ductwork. Filter must always be used and must be kept clean. When filters become dirt laden, insufficient air will be delivered by the blower, decreasing your units efficiency and increasing operating costs and wear-and-tear on the units and controls. Filters should be checked monthly especially since the unit may be used for both heating and cooling When the air conditioner is not going.... When it is not going to be used for a long time. - Operate the air conditioner on Air circulation mode for 2 to 3 hours. This will dry out the internal parts. - Turn off the circuit breaker. ! 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 Controller. When the air conditioner is to be used again. - Check that the air inlet and outlet of the indoor/outdoor unit are not blocked. ENGLISH Operation Tips! 14 MAINTENANCE AND SERVICE ENGLISH Troubleshooting Tips! Save time and money! Check the following points before requesting repairs or service.... If the malfunction persist, please contact your dealer. The air conditioner does not operate. - Have you made a mistake in timer operation? - On first starting, the indoor unit operates in fifteen seconds. - Has the fuse blown or has the circuit breaker been tripped? 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. Does not cool or heat effectively. - Is the air filter dirty? See air filter cleaning instructions. - The room may have been very hot when the room air conditioner was first turned on. Allow time for it to cool down. - Has the temperature been set incorrectly? - Are the indoor unit's air inlet or outlet vents obstructed?
