CONTROLS OPERATIONS FAN CONTROL OFF- completely shuts off the unit. To prevent blowing fuses, wait two minutes after turning the unit off before turning it on again. LOW COOL Filters and circulates room air with the fan running continuously on low speed. Also cools and dehumidifiers while the compressor is running. Select this setting for quiet cooling operation. HIGH COOL- Filters and circulates room air with the fan running continuously on high speed. Also cools and dehumidifies while the compressor is running. Select this setting for maximum air circulation and cooling effect. LOW HEAT Filters and circulates room air with the fan running continuously on low speed. Also heats while the compressor or electric heat is running. Select this setting for quiet heating operation. HIGH HEAT Filters and circulates room air with the fan running continuously on high speed. Also heats while the compressor or electric heater is running. Select this setting for maximum air circulation and heating effect. FAN ONLY Select this setting for circulating or exhausting room air without cooling. TEMPERATURE CONTROL Slide this control to the left for a warmer room temperature, to the right for a cooler room temperature. Page 8
INSTALLATION INTRUCTIONS Installation Precaution Incorrect installation of the unit may lead to death, personal injury, or property damage. Only trained, qualified installers and service personnel are allowed to install, start-up, and service this equipment. Casualty, injury or damage due to incorrect installation or installation by unqualified personel will not be assumed by us. Location Install the unit where: The condensate can be easily drained out. It is with a minimum distance of 1m away from TV set or any other electric appliance. There is no leakage of inflammable gas. There is no other heat source or direct sunlight. It is out of reach of children. Do not install the unit in a laundry, or a bathroom or around a swimming pool, etc. Consult your seller before installation when the unit is to be installed in an area where salt-laden air prevails (conlse to coastal areas, etc), the air contains sulphurous gas (in hot spring zones), or there are other special conditions. For window type air conditioner with a remote controller, contact your seller when it is to be installed in a place where there is strong electromagnetic interference. How to install Choose a location where there is not any obstacle surrounding the unit. Prepare the installation hole a little bigger than the size of the unit. Choose the installation space according to the diagrams in Page 4. Installation Procedure: 1. Remove the sticker from the front panel. 2. Put the unit into the installation hole. When installing, make sure the unit is slanted downward to the back to minimize the noise and vibration of operation. (Slant by 6-10mm) Mark sure the installation place is strong enough to minimize the noise and vibration of operation. 3. Fill the gaps in the cabinet with sponge or foam. Page 9
Install the auxiliaries: Adopt an iron stand Installation hole should be arranged such that it can support the whole air conditioner, if not, an outdoor iron stand should be adopted for support. Iron stand should be fixed to the building securely. Set up the sun shield Air conditioner should be protected from foreign material drop-in or direct solarization. In case there is no safeguard over the machine, please contact your distributor for mounting a sun shield; but it should be ensured that the sun shield must not seriously blockade the inlet air at upper grille of the air conditioner. Drain Water To maximize cooling efficiency, the air conditioner is designed to spray condensate water to the condenser coil. For cooling only unit, if the spraying sound is annoyed, you could drain the condensate water through following steps, which may lead to a small loss of performance. 1. Slide out the unit from the cabinet. 2. Remove the rubber plug from the base-pan. 3. Install the drain pan to the corner of the cabinet with 2 screws. 4. Connect the drain hose to the outlet on the bottom of the drain pan. 5. Slide the unit into its original place in the cabinet. NOTES: Drain pan and drain hose must be installed before operation. Drain hose or tubing is not provided with unit. Should purchase separately. Page 10

TROUBLE SHOOTING Precautions before performing inspection or repair Be cautious during installation and maintenance. Do operation following the regulations to avoid electric shock and casualty or even death due to drop from high attitude. Static maintenance is the maintenance during de-energization of the air conditioner. For static maintenance, make sure that the unit is de-energized and the plug is disconnected. Dynamic maintenance is the maintenance during energization of the unit. Before dynamic maintenance, check the electricity and ensure that there is ground wire on the site. Check if there is electricity on the housing and connection copper pipe of the air conditioner with voltage tester. After ensure insulation place and the safety, the maintenance can be performed. Malfunction Analysis Problem Possible Defective What to do Air conditioner does not start The air conditioner is unplugged Make sure the air conditioner plug is pushed completely into the outlet. The fuse is blown/circuit breaker is tripped Check the house fuse/circuit breaker box and replace the fuse or reset the breaker. Power failure The unit will automatically re-start in last settings. There is a protective time delay (3-minutes) to prevent tripping of the compressor overload. For this reason, the unit may not start normal cooling or heating for 3 minutes after it is turned back on. The current interrupter device is tripped. Press the RESET button on power cord plug. If the RESET button will not stay engaged, discontinue use of the unit and contact a qualified device technician, The conditioner Ice block the air flow and stops the air Set the mode control at FAN freezing up conditioner from cooling the room.

Excessively hot and humid weather The air conditioner is not tilted to the outside Moisture is removed from indoor air and drain into rear of a cabinet where a fan blows it against the outdoor condenser coil. blocking the front of the air conditioner. Turn the temperature knob clockwise as far as possible. Clean the filter at least every 30 days. See the operating instructions section. When the air conditioner is first turned on, you need to allow time for the room to cool down. Check for open furnace floor registers and cold air returns. Se the air conditioner s vent to the closed position. See Air conditioner freezing up Makes sure there are no curtains, blinds or furniture blocking the front of the air conditioner Turn the knob counterclockwise as possible. The lowest setting provides maximum warming. Clean the filter at least every 30 days. See the operating instructions section. When the air conditioner is first turned on, you need to allow time for the room to warm up. Check for open furnace floor registers and cold air returns. This is normal. For proper water disposal, make sure the air conditioner slants slightly from the case front to the rear. This is normal for a short period in areas with little humidity. Normal for a longer period in very humid areas. Page 17
