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.

BEFORE USE 7 Preparing for operation • Contact an installation specialist for installation. • Use a dedicated circuit. Usage • Being exposed to direct airflow for an extended period of time could be hazardous to your health. Do not expose occupants, pets, or plants to direct airflow for extended period of time. • Due to the possibility of oxygen deficiency, ventilate the room when used together with stoves or other heating devices. • Do not use this air conditioner for non-specified special purposes (e.g. preserving precision devices, food, pets, plants, and art objects). Such usage could damage the items. Cleaning and maintenance • Do not touch the metal parts of the unit when removing the filter. Injuries can occur when handling sharp metal edges. • Do not use water to clean inside the air conditioner. Exposure to water can destroy the insulation, leading to possible electric shock. • When cleaning the unit, first make sure that the power and breaker are turned off. The fan rotates at a very high speed during operation. There is a possibility of injury if the unit’s power is accidentally triggered on while cleaning inner parts of the unit.

MAINTENANCE AND SERVICE 15 Filter Cleaning Indoor Unit Grille, Case and Remote Control - Turn the system off before cleanining, To clean, wipe with a soft, dry cloth. Do not use bleach or abrasives. ! Please clean it once in a week. 1 Remove the Air filters. - Take hold of the tab and pull slightly forward to remove the filter. ! CAUTION NOTE Supply power must be disconnected before cleaning the indoor unit. When the air filter is to be removed, do not touch the metal parts of the indoor unit. It may cause an injury. Air Filters The air filters behind the front grille should be checked and cleaned once every 2 weeks or more often if neccessary. - 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. 2 Clean dirt from the air filter using a vacuum cleaner or washing with water. - If dirt is conspicuous, wash with a neutral detergent in lukewarm water. SI Be n zene N NER SCO U RIN G C LB A R GER - If hot water (50°C or more) is used, it may be deformed. 3 After washing with water, dry well in the shade. - Do not expose the air filter to direct sunlight or heat from a fire when drying it. 4 Install the air filter. ENGLISH MAINTENANCE AND SERVICE 16 MAINTENANCE AND SERVICE ENGLISH 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. 1 Operate the air conditioner at the following settings for 2 to 3 hours. - Type of operation: Fan operation mode. - This will dry out the internal mechanisms. When the air conditioner is to be used again. 1 Clean the air filter and install it in the indoor unit. 2 Check that the air inlet and outlet of the indoor/outdoor unit are not blocked. 3 Check that the ground wire is connected correctly. It may be connect to the indoor unit side. ! 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. 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. Operation Tips 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 reduces the airflow and lowers the 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. MAINTENANCE AND SERVICE 17 Check the following points before requesting repairs or service....

Crack sound is heard. - This sound is generated by the expansion/ constriction of the front panel, etc. due to changes of temperature. Remote control display is faint, or no display at all. - Are the batteries depleted? - Are the batteries inserted in the opposite (+) and (-) directions? Filter sign lamp (LED) is ON. - Cleaning the filter, press the Timer button and ◀ button of wired remote control at the same time for 3 sec. The error code is occurred after lightning struck - This product has been applied to the over current protection circuit. Error can occur, but it is normal behavior. After few minutes, It will operate normally. The air conditioner operation is noisy. - 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. Call the service immediately in the following situations 1 Anything abnormal such as burning smell, loud noise etc. happen. Stop the unit and turn the 2 3 4 5 breaker off. 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 even if the humidity is low. 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 service person only. ENGLISH Troubleshooting Tips! Save time and money!
