Opening the front panel Pull up from two ends of the front panel. Open the panel and lift the panel up to an angle where it remains fixed. Do not lift the panel any further when it stops with a clicking sound. Closing the front panel Lower ends of the front panel, push the ends on both sides. Close the panel firmly. Temporary Normally set this switch to remote control. If you miss the remote controller or its batteries are exhausted, set this switch to the Auto/Cool Position for temporary operation. 4 ADJUSTING AIR FLOW DIRECTION To automatically swing the air flow direction Perform this function while the air conditioner is in operation. Push the SWING button on the remote controller. To stop the function, push the SWING button again. To change the swing direction, push the AIR DIRECTION button. . . CAUTIONS The AIR DIRECTION and SWING buttons will be disabled when the air conditioner is not in operation (including when the ON TIMER is set). Do not operate the air conditioner for long hours with the air flow direction set downward during the cooling or dry operation. Otherwise, condensation may occur on the surface of the vertical air flow louver and cause dew dripping. Do not move the vertical louver manually. Always use the AIR DIRECTION button. If you move the louver manually, it may malfunction during operation. If the louver malfunctions, stop the air conditioner once and restart it. When the air conditioner is started immediately after it was stopped, the vertical air flow louver might not move for 10 seconds or so. Hold Adjusting the Horizontal Air Flow Direction Preparation: . . For the cooling or dry operation, move the vertical air flow louver downward using the AIR DIRECTION button on the remote controller. Take hold of the lever on the horizontal air flow grilles and move them to adjust the air flow direction as required. For the cooling or dry operation, return the vertical air flow louver to the original position using the AIR DIRECTION button on the remote controller. If your use the AIR DIRECTION button to set the vertical air flow direction, the direction will move downward at first, then turn automatically to the direction as you desire. When you stop operating with the remote controller, the vertical air flow louver will shut automatically. 5 HOW THE AIR CONDITIONER WORKS Operation suppression zone . . . AUTOMATIC OPERATION The air conditioner selects and operates in one of the operating modes of cooling, heating (cooling only type without) or fan only, depending on the room temperature. The air conditioner will control room temperature automatically round the temperature point set by you. If the Auto mode is uncomfortable, you can select the desired conditions manually. Operation starts ¡£ 1C ¡£ 2C 1 hours Set temperature 2 hours ECONOMIC Operation ECONOMIC OPERATION When your push ECONO button during cooling, heating (cooling only type without), or AUTO operation, the air conditioner will start following operation. The fan speed will be automatically controlled. In the operation suppression zone where capacity is kept to the minimum, overcooling is ¡£ prevented by raising the temperature setting by 1 C after 1 ¡£ hour and by 2 C after 2 hours of operation. The room temperature is thus regulated between the operation suppression zone and the set temperature. (It depends on the outdoor temperature.) Cooling Fan only Cooling Fan only Cooling Room temperature Time Set temperature Dry DRY OPERATION The dry mode will automatically select the cooling dry operation based on the difference between the set temperature and the actual room temperature. TEMPORARY OPERATIONS Indoor unit The temperature is regulated while dehumidifying by repeating turning on and off of the cooling operation or fan only. The fan speed indicator will display AUTO and low speed will be used. Temporary Operation AUTO/COOL TEMPORARY Switch . . A temporary operation feature is provided This function is used to operate the unit temporarily in case you misplace the remote controller or its batteries are exhausted. Set the TEMPORARY switch to the AUTO position in order to start the automatic operation. The COOL position is provided for test runs of the unit, and automatic temperature control is cut off at this position. Never use the position for ordinary operation. I cannot find the remote controller 6 MAINTENANCE WARNING WARNING Before you clean the air conditioner, be sure to disconnect the power supply plug. Cleaning the indoor unit and the remote controller Use a dry cloth to wipe CAUTIONS Use a dry cloth to wipe the indoor unit and remote controller.

Do not use benzine, thinner, polishing powder, or similar solvents for cleaning. These may cause the plastic surface to crack or deform. Thinner Select fan only mode If you do not plan to use the unit for at least 1 month. (1) Operate the fan for about half a day to dry the inside of the unit. (2) Stop the air conditioner and disconnect power. (3) Remove the batteries from the remote controller. Checks before operation CAUTIONS Check that the wiring is not broken off or is not connected. Check that the air filter is installed. Check that the outdoor unit air outlet or inlet is not blocked. Before you clean the air conditioner be sure to disconnect the power supply plug. Cleaning the air filter 1. Pull up from two ends of panel. Open the panel and lift the panel up to an angle where it remains fixed. Do not lift the panel any further when it stops with a clicking sound. 2. Take hold of the left and right handles of the air filter and lift it up slightly to take it out from the filter holder. Air Filter Handle 7 MAINTENANCE 3. Take hold of the handles and pull the air filter downward. 4. Remove the AIR FILTER from the indoor unit. Clean the AIR FILTER once two weeks. Clean the AIR FILTER with a vacuum clearer or water, then dry it up in cool place. 5. Remove the ACTIVE CARBON FILTER/ELECTRO STATIC FILTER from the indoor unit and take it out from its support frame. Clean the filter every month, immerse the filter in the water with the mild detergent for 20 minutes and wash it slightly (do not rub), then expose it in the sun to dry it out for more than 3 hours. (put the black side face up) 6. Install the filters into their support frames and set the support frames back in position. The black side of the filters be at the outsides. 7. Insert the AIR FILTER from the top side into the unit until it is fixed thoroughly and close the front panel of the indoor unit tightly. Optional filter 8 AIR CONDITIONER OPERATIONS AND PERFORMANCE Three-minute protection feature A protection feature prevents the air conditioner from being activated for approximately 3 minutes when it is restarted immediately after operation. This will protect the machine. (cooling only type without) Heating characteristics preheating operation The air conditioner will not deliver warm air immediately after it is started. Warm air flows out after approximately 5 minutes when the indoor heat exchanger warms up. Warm air control When the room temperature reaches the set temperature, the fan speed is automatically reduced to prevent a cold draft. At this time, the outdoor unit will stop. Defrosting If the outdoor unit is frosted during heating operation, defrosting is started automatically (for approximately 5 to 10 minutes) to maintain the heating effect, and the PRE.-DEF. lamp is on. The fans in both the indoor and outdoor units stop during the defrost operation. Duri ...
