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. Outdoor unit  Installation of Outdoor Unit Install according to Drawing for the installation of indoor and outdoor units  Connection of pipes ƽ To bend a pipe, give the roundness as large as possible not to crush the pipe , and the bending radius should be 30 to 40 mm or longer. ƽ Connecting the pipe of gas side first makes working easier. ƽ 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(Φ) Fastening torque Liquid side6.35mm(1/4") 18N.m Liquid/Gas side9.52mm(3/8") 42 N.m Gas side 12.7mm(1/2") 55N.m Gas side 15.88mm(5/8") 60 N.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 B Indoor unit A Outdoor unit Outdoor unit B A Oil trap Indoor unit Outdoor unit B A Indoor unit ● Max.Elevation: Amax=10m ● In case the elevation A is more than 5m, oil trap shoud be installed every 5~7m ● Max. Length: Bmax=15m ● In case the pipe length B is more than 7m, the refrigerant should be charged, according to 20 g/m.  Connection ƽ Use the same method on indoor unit. Loosen the screws on terminal block and insert the plugs fully into terminal block, then tighten the screws. ƽ Insert the cable according to terminal number in the same manner as the indoor unit. ƽ If wiring is not correct, proper operation can not be carried out and controller may be damaged. ƽ Fix the cable with a clamp. 3
