If you want to use this operation, open the front panel upward and Press the power button let it be pressed for about 3 seconds. If you want to stop the operation, re-press the button. Auto restart In case the power comes on again after a power failure, Auto Restarting Operation is the function to operate procedures automatically to the previous operating conditions. So there is no need of activating this function by pressing any key or button. In the initial mode, the fan operates at a low speed and the compressor starts 2.5~3 minutes later. As the compressor starts, the fan speed also resumes its previous setting mode. Additionally, in order to cancel auto restart operation press power button let it be pressed for about 6 seconds. To operate auto restart operation again, press power button for about 6 seconds as well. Helpful information Fan speed and cooling capacity. The cooling capacity indicated in the specification is the value when the fan speed is set to high, and the capacity will be lower at low or medium fan speed. High fan speed is recommended when you wish to cool the room quickly. 12 h Hig ed e Sp CAUTION: Before performing any maintenance, turn off the main power to the system. Indoor Unit Grille, Case, and Remote Control ❏ Turn the system off before cleaning. To clean, wipe with a soft, dry cloth. Do not use bleach or abrasives. NOTE: Supply power must be disconnected before cleaning the indoor unit. ❏ 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. d er G a s o li n e AIR FILTERS 1 Lift the front access panel and pull the filter tab slightly forward to remove the filter. The air filters behind the front grille should be checked and cleaned once every 2 weeks or more often if neccessary. 2 Clean the filter with a vacuum or warm, soapy 3 After washing with water, dry well in the shade. 4 Re-install the air filter.

When air conditioner is not going to be used for a long time. When the air conditioner is to be used again. Turn off the circuit breaker, and disconnect the plug. Clean the air filter and install it in the indoor unit. (Refer to page 13 for cleaning filters.) 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. Check that the air inlet and outlet of the indoor/outdoor unit are not blocked. Remove the batteries from the remote control. Operation Tips Do not overcool the room. Keep blinds or curtains closed. Keep the room temperature uniform. This is not good for the health and wastes electricity. Do not let direct sunshine enter the room when the air conditioner is in operation. 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. Clean the air filter regularly. Ventilate the room occasionally. Avoid opening doors and windows as much as possible to keep the cool air in the room. Blockages in the air filter reduce the airflow and lower cooling and dehumidifying effects. Clean at least once every two weeks. Since windows are kept closed, it is a good idea to open them and ventilate the room now and then. 14 Before you call for service... Troubleshooting Tips! Save time and money! Check the following points before requesting repairs or service.... If the fault persists, please contact your dealer or service center. Case Explanation See page The air conditioner does not operate. • Have you made a mistake in timer operation? • Has the fuse blown or has the circuit breaker been tripped? - - It seems that condensation is leaking from the air conditioner. • Condensation occurs when the airflow from the air conditioner cools the warm room air. - Air conditioner does not operate for about 3 minutes when restarted. • This is the protector of the mechanism. • Wait about three minutes and operation will begin. - Does not cool or heat effectively. • Is the air filter dirty? See air filter cleaning instructions. • Has the temperature been set incorrectly? • Are the indoor unit's air inlet or outlet vents obstructed? The air conditioner operation is noisy. 13 7 - - Remote control display is faint, or no display at all. • Are the batteries depleted? • Are the batteries inserted in the opposite (+) and (-) directions? 4 Crack sound is heard. • This sound is generated by the expansion/constriction of the front panel, etc. due to changes of temperature. - NOTE WATER RESISTANT: The outdoor side of this appliance is WATER RESISTANT. The indoor side is not water resistant and should not be exposed to excess water. 15 Troubleshooting Tips • 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. Care and Maintenance • Check that this is not a damp smell exuded by the walls, carpet, furniture, or cloth items in the room. Operating Instructions The room has a peculiar odor. Safety Precautions ?
