ENGLISH FRANÇAIS OWNER’S MANUAL AIR CONDITIONER Please read this manual carefully before operating your set and retain it for future reference. CEILING CASSETTE www.lg.com P/NO : MFL68120701 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.

Replacement Recomended use period : About 2 years - After removing the air filters, pull slightly forward to remove the PLASMA filter. - Dip the PLASMA filter into the water mixed with neutral detergent, for 20~30 minutes. - Dry the PLASMA filter in the shade for a day (Especially, the humidity must be removed perfectly on this parts). - Note the cuts of electric discharge lines. - Remove air purifying filter. - Open front panel and remove air filter. - Insert new air purifying filter. 1 2 - Re-install the PLASMA filter to the original position. - Reinsert air filter and close front panel. ! CAUTION Don’t touch this PLASMA Filter within 10 seconds after opening the inlet grille, it may cause an electric shock. MAINTENANCE AND SERVICE 29 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 operation. Keep the room temperature uniform. 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. Avoid opening doors and windows as much as possible to keep the cool air in the room. Clean the air filter regularly. Blockages in the air filter reduce the airflow and lower cooling and dehumidifying effects. Clean at least once every two weeks. Ventilate the room occasionally. Since windows are kept closed, it is a good idea to open them and ventilate the room now and then. When the air conditioner is not going.... When air conditioner is not going to be used for a long time. - Operate the air conditioner at the following settings for 2 to 3 hours. Type of operation: Fan operation mode. (Refer to page “Fan Mode”.) This will dry out the internal mechanisms. - Turn off the breaker. ! CAUTION Turn off the 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. Helpful information The air filters and your electiric bill. If the air filters become clogged with dust, the cooling capacity will drop, and 6% of the electricity used to operate the air conditioner will be wasted. When the air conditioner is to be used again. - Clean the air filter and install it in the indoor unit.
