Operation hints Unit operation Protection devices inside the unit will activate to stop unit operation, when ambient temp. is extremely low or high. When unit is running under high humidity in cooling or dehumidifying mode, condensate might appear at outlet grill. 3-min delay protection Unit will not restart until 3 min have elapsed for the protection of the unit. Fan speed changes When Fan speed is set at Auto in cooling mode, it will be automatically reduced as room temp. is approaching temp. setting.
Energy saving Keep proper room temp. Too cold or too warm is no good to your health, and power consumption will be increased as well. Proper temp. Air filter should be periodically cleaned If air filter is clogged: It will cause poor cooling and heating efficiency, higher power consumption and even problem may occur. In cooling operation, water will flow out. Use Timer effectively You may use Timer mode to keep a comfortable room temp.when ON AM 8:00 OFF PM 5:00 you wake up or come home from outside.
Maintenance Disconnect power supply Don't touch it with wet hand Don't wash with hot water or solvent to clean the unit Don't spray any paint or insecticide on the unit. Don't splash water directly on indoor unit. This could be very dangerous This will cause damage or even fire accident. Air filter cleaning Pull it out from top as shown in Fig. Use water or vacuum cleaner to clean it. If it is extremely dirty, wash it with neutral detergent or soap water.

Don't use water higher than 40 C , which will cause discoloring and deformation. Don't use insecticide or other chemical detergents.
Trouble shooting Followings are not problems Sound of water flowings are not problems. During unit start and operation or at stop, a swishing or gurgling noise may be heard. This noise is generated by refrigerant flowing in the system. Sound of cracking is heard. During unit operation, a cracking noise may be heard. This noise is generated by the casing expanding or shrinking because of temperatuer changes. Smells are generated.
When problems occur Before asking services, please firstly check your unit according to following. Air conditioner won't start. Is power supply switch turned on? Power supply switch is not set at ON. Is city power supply normal? Is leakage current breaker activated? This is very dangerous, please disconnect power supply immediately and contact your dealer.
When problems occur Power supply The parameter of power cord is over 5G 2.5mm2. The parameter of connect cord is 4G 0.75mm2 . Air conditioner must use an exclusive line (over 30A) When installation air conditioner in a wet place, try to use a circuit breaker against current leakage. For installation in other places, use circuit breaker as far as possible. The breaker of the air conditioner should be all-pole switch ; and the distance between its two contacts should be no less than 3 mm.

Installation procedures Display of whole unit Try to bring the packed unit to the installation place. When it is inevitable to unpack the unit, be careful not to damage the unit. Wrap it with nylon etc. After unpacking, be sure to put it with the front side of the unit facing up. Delivery Facing up Note: When delivering, don't hold plastic parts like inlet and outlet grill etc.
Installation procedures Installation of indoor unit Selection of installation place Place where it is easy to route drainage pipe and outdoor piping. Place away from heat source and with less direct sunlight. Place where cool and warm air could be delivered evenly to every corner of the room. Place near power supply socket. Leave enough space around the unit (refer to installation drawings). Fixing of the unit 1.
Installation procedures Installation of fall-prevention fitting metal: Fix the fitting metal to the wall by screws so that there is no clearance between them. With the unit set up vertically, fix the fitting metal to the unit with screws while making an adjustment at the long portion of the hole so that there is no clearance between the upper surface and the fitting metal. Installation of L-shaped metal Fix to the unit by screws so that there is no clearance between the fitting metal and the unit.
Installation procedures 2. Piping connection of indoor unit Arrangement of piping and drainage pipe After opening inlet grill, you will see a control box as shown in the Fig. Remove the cover before wiring work. Cut away, with a hammer or a saw, the lid for piping according to piping direction. Insulation material Copper tube Drain hose Connecting electric cable for indoor and outdoor unit According to the piping method, connect the piping on indoor unit with union of connecting pipe.
Installation procedures 3. Piping connection of outdoor unit. Connect the connecting pipe and inlet and outlet liquid pipe according to the piping method. 4.Purging method Discharge the air out of the indoor unit and the refrigerant pipe by vacuumizing (1) Fasten all the nuts of the indoor and outdoor pipes to make these parts out of leakage. (2) Under the condition of the complete close of the indoor and outdoor valve center (both liquid and gas side),dismount the repair valve cap.
Installation procedures Electric wiring Note: Electric wiring must be done by qualified person. Use copper wire only, the parameter of connecting cable is H07RN-F 4G 0.75mm2. The power cable should be over 5G2.5mm2, the power cable and connecting cable are self-provided. The power supply connects from the outdoor unit. Wiring of indoor unit Insert the cable from outside the wall hole where piping already exist. Pull it out from front.
