Controls OPERATION High Cool ( ), Med Cool ( ) and ) provide cooling with different fan Low Cool ( speeds. Med Fan ( ) or Low Fan ( ) provides air circulation and filtering without cooling. Off ( O ) turns the air conditioner off. NOTE: If you move the switch from a cool setting to off or to a fan setting, wait at least 3 minutes before switching back to a cool setting. Operating Instructions Cooling Descriptions THERMOSTAT (TEMPERATURE) The THERMOSTAT/TEMPERATURE is used to maintain the room temperature. The compressor will cycle on and off to keep the room at the same level of comfort. When you turn the knob to a higher number (the right side) and the indoor air will become cooler. The 5 or 6 position (the middle position of arc) is a normal setting for average conditions. For Normal Cooling- Select High Cool or Med Cool with the OPERATION knob at the midpoint of THERMOSTAT/TEMPERATURE knob. For Maximum Cooling- Select High Cool with the OPERATION knob at the highest number available on your THERMOSTAT/TEMPERARURE knob. For Quieter & Nighttime Cooling- Select Low Cool with the OPERATION knob at the midpoint of THERMOSTAT/TEMPERATURE knob. OPERATION HIGH ( ) Cool, LOW ( ) Cool provide cooling with different fan speeds. HIGH ( )heat, LOW( ) heat provide heating with different fan speeds. FAN ( ) provides air circulation and filtering without cooling or heating. OFF ( O ) turns the air conditioner off. NOTE: If you move the switch from the cool(or the heat) setting to off or to a fan setting, wait at least 3 minutes before switching back to a cool(or heat) setting. Cooling Descriptions THERMOSTAT (TEMPERATURE) The THERMOSTAT/TEMPERATURE is used to maintain the room temperature. The compressor will cycle on and off to keep the room at the same level of comfort.

Be sure that the (+) and (-) directions are correct. Be sure that both batteries are new. Re-attach the cover. Slide it back into the position. Do not use rechargeable batteries, such batteries differ from standard dry cells in shape, dimensions, and performance. Remove the batteries from the remote controller if the air conditioner is not going to be used for an extended length of time. -6- Additional controls and important information. Vent Control The vent control is located above the control knobs. When set at CLOSE, only the air inside the room will be circulated and conditioned. When set at OPEN, some inside air is exhausted outside. To open the vent, pull the lever toward you. To close it, push it in. Operating Instructions Air Direction The direction of air can be controlled horizontally or vertically by using the horizontal louver or vertical louver. Horizontal Air-Direction The horizontal air direction is adjusted by setting the AUTO SWING switch to the ON position. Vertical Air-Direction Fingertip pressure on the bank of horizontal louvers adjusts the air direction up or down -7- Care and Maintenance Grille and Case Turn the air conditioner off and remove the plug from the wall outlet before cleaning. To clean, use water and a mild detergent. Do not use bleach or abrasives. Air Filter Operating Instructions Ensure the power is off before open the front Grill. The air filter behind the front grille should be checked and cleaned at least once every 2 weeks or more often if necessary. The grille is designed to clean the filter both upward and downward. To remove: Open the inlet grille upward by pulling out the bottom of the inlet grille or downward by pulling out the top of the inlet grille. Using the tab, pull up slightly on the filter to release it and pull it down or up. Clean the filter with warm, soapy water below 40°C (104°/F). Rinse and gently shake the water from the filter and let it dry before replacing it. CAUTION: DO NOT operate the air conditioner without a filter because dirt and lint will clog it and reduce performance. Drainage In humid weather, excess water may cause the BASE PAN to overflow. To drain the water, remove the DRAIN CAP and secure the DRAIN PIPE to the rear hole of the BASE PAN. To remove the condensed water, you can install the drain pan as below. 1. Take the drain pan which is located in the air discharge. 2. Install the drain pan to the right corner of the cabinet with 4 screws. 3. Connect the drain hose to the outlet located at the bottom of the drain pan. You can purchase the drain hose or tubing locally to satisfy your particular needs. (Drain hose is not supplied). -8- Features Learning parts name prior to installation will help you understanding the installation procedure. Features 1. CABINET 2. FRONT GRILLE 3. AIR FILTER 4.

HORIZONTAL AIR DEFLECTOR (VERTICAL LOUVER) Installation Instructions Select the Best Location To prevent vibration and noise, make sure the unit is installed securely and firmly. Install the unit where the sunlight does not shine directly on the unit. There should be no obstacle, such as a fence or wall, within 50cm from the back of the cabinet because it will prevent heat radiation of the condenser. Restriction of outside air will greatly reduce the cooling efficiency of the air conditioner. Install the unit a little obliquely outward not to leak the condensed water into the room (about 10 ~ 15mm or 1/4 bubble with level). CAUTION: All side louvers of the cabinet must remain exposed to the outside of the structure. 9. 10. 11. 12. 13. 14. 15.
