Unloading of indoor unit body When you unload the indoor unit,please use your hand to arise the body to leave agraffe,then lift the bottom of the body outward slightly and lift the unit aslant until it leaves the mounting plate. agraffe mounting plate 3 Indoor unit Indoor unit Connecting the indoor/outdoor Electric Cable Removing the wiring cover Remove terminal cover at right bottom corner of indoor unit, then take off wiring cover by removing its screws. When connecting the cable before installing the indoor unit When connecting the cable after installing the indoor unit 1. Insert from outside the room cable into left side of the wall hole, in which the pipe has already existed. 2. Pull out the cable on the front side, and connect the cable making a loop. Insert the cable from the back side of the unit, then pull it out on the front side. Loosen the screws and insert the cable ends fully into terminal block, then tighten the screws. Pull the cable slightly to make sure the cables have been properly inserted and tightened. After the cable connection, never fail to fasten the connected cable with the wiring cover. Note: When connecting the cable, confirm the terminal number of indoor and outdoor units carefully. If wiring is not correct, proper operation can not be carried out and will cause defect. 1. If the supply cord is damaged, it must be replaced by the manufacturer or its service agent or a similar qualified person. The type of connecting wire is H05/07RN-F or 245IEC57(YZW). 2. If the fuse on PC board is broken please change it with the type of T. 3.15A/250V. 3. The wiring method should be in line with the local wiring standard. 4. After installation, the power plug should be easily reached. 5. A breaker should be incorporated into fixed wiring. The breaker should be all-pole switch and the distance between its two contacts should be not less than 3mm.

Connecting the pipe of gas side first makes working easier. The connection pipe is specialized for R410A. Half union Flare nut Forced fastening without careful centering may damage the threads and cause a leakage of gas. Spanner Torque wrench Pipe Diameter Fastening torque Liquid side 6.35mm(1/4") 18N.m Gas side 9.52mm(3/8") 42N.m Gas side 12.7mm(1/2") 55N.m Be careful that matters, such as wastes of sands, etc. shall not enter the pipe. The standard pipe length is 5m. If it is over 7m, the function of the unit will be affected. If the pipe has to be lengthened, the refrigerant should be charged, according to 20 g/m. But the charge of refrigerant must be conducted by professional air conditioner engineer. Before adding additional refrigerant, perform air purging from the refrigerant pipes and indoor unit using a vacuum pump,then charge additional refrigerant. CAUTION In case the elevation A is more than 5m, oil trap shoud be installed every 5~7m Max. Length: Bmax1=15mMax.Elevation: Amax1=10m In case the pipe length B is more than 7m, the refrigerant should be charged, according to 20 g/m.

Loosen the screws on terminal block and insert the plugs fully into terminal block, then tighten the screws. Insert the cable according to terminal number in the same manner as the indoor unit. If wiring is not correct, proper operation can not be carried out and controller may be damaged. Fix the cable with a clamp. 4.Attaching Drain-Elbow If the drain-elbow is used, please attach it as figure. Drain hose Note: Only for heat pump unit. 5 Drain elbow Outdoor unit Outdoor unit 5.Purging Method:To use vacuum pump Liquid Side Gas Side Detach the service port's cap of 3-way valve, the valve rod's cap for 2-way valve and 3-way's, connect the service port into the projection of charge hose (low) for gaugemanifold. Then connect the projection of charge hose (center) for gaugemanifold into vacuum pump. Tube(for R410A) Open the handle at low in gaugemanifold, operate vacuum pump. If the scale-moves of gause (low) reach vacuum condition in a moment, check again. Vacuumize for over 15min. And check the level gauge which should read -0.1 MPa (-76 cm Hg) at low pressure side. After the completion of vacuumizing...
