8.

Disconnect one-touch joint between high-pressure pipe 1 (1)
and high-pressure pipe 2 (2) with disconnector (A) (SST:
9253089908).

CAUTION:

Cap or wrap the joint of the A/C piping with suitable mate-
rial such as vinyl tape to avoid the entry of air.

9.

Remove high-pressure pipe 1.

INSTALLATION

Installation is basically the reverse order of removal.

CAUTION:

• Replace O-rings with new ones. Then apply compressor oil to them when installing.
• Female-side piping connection is thin and easy to deform. Slowly insert the male-side piping

straight in axial direction.

• Insert piping securely until a click is heard.
• After piping connection is completed, pull male-side piping by hand to make sure that connection

does not come loose.

• Check for leakages when recharging refrigerant.
