Precautions for refrigerant piping
■ Do not twist or crush piping.
■ Be sure that no dust is mixed in piping.
■ Bend piping with as wide angle as possible.
■ Keep insulating both gas and liquid piping.
■ Check are-connected area for gas leakage.
4 Piping connection method
■ Apply refrigerant oil to the joint and the ange.
■ To bend a pipe, give the roundness as possible not
to crush the pipe.
■ When connecting pipe, hold the pipe centre to
centre and then screw nut on by hand, refer to Fig.
■ Be careful not to let foreign matters, such as sands
enter the pipe.
Pipe diameter Fastening torque (N.m)
Liquid pipe Ф6.35mm 14.2-17.2
Liquid pipe Ф9.52mm 32.7-39.9
Gas pipe Ф12.7mm 49.5-60.3
Gas pipe Ф15.88mm 61.8-75.4
Gas pipe Ф19.05mm 97.2-118.6
Forced fastening without centering may damage the threads and cause a gas leakage.
5. For the allowable pipe length and height difference for maxi split system, please see the table in the page
2 of this manual.
