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.

(4) Piping connection

Connecting method (indoor unit)

Apply refrigerant oil at half union as large and flare nut. To bend a pipe, give the roundness as possible not to crush the pipe.

When connecting pipe, hold the pipe centre to centre then screw nut on by hand, refer to Fig.

Be careful not to let foreign matters, such as sands enter the pipe.

Forced fastening without centering may damage the threads and cause a gas leakage.
