3. Limitations for one way piping length and vertical height difference
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 flare-connected area for gas leakage.
Apply refrigerant oil to the joint and the flange.
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.
4. Piping connection method
Forced fastening without centering may damage the threads and cause a gas leakage.
