Connection of pipes 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. Connecting the pipe of gas side first makes working easier. The connection pipe is specialized for R410A. The max vertical distance between the indoor unit and the outdoor unit is 5 m. Half union Flare nut Forced fastening without careful centering may damage the threads and cause a leakage of gas.

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. [. . . ] 6 If it does not stop gas leakage, discharge whole refrigerants from the service port. After flaring work again and vacuumize, fill up prescribed refrigerant from the gas cylinder. 2-way valve 2-way valve 3-way valve 6 Detach the charge hose from the service port, open 2-way valve and 3-way. In case that the attached drain hose is in a room, please apply heat insulation to it without fail.
