4.
Remove mounting bolt (A) from low-pressure flexible hose
bracket (1).
5.
Disconnect one-touch joint between low-pressure flexible hose
(2) and low-pressure pipe 2 (3) with disconnector (B) (SST:
9253089916).
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.
6.
Remove mounting nut (A), and then remove low-pressure flexi-
ble hose (1).
CAUTION:
Cap or wrap the joint of the A/C piping and compressor with
suitable material such as vinyl tape to avoid the entry of air.
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.
