4.

Disconnect one-touch joints.

a.

Set a disconnector (SST: 9253089916) on A/C piping.

b.

Slide a disconnector toward vehicle front until it clicks.

c.

Slide A/C piping toward vehicle front and disconnect it.

CAUTION:

Cap or wrap the joint of low-pressure pipe 1 and low-pres-
sure flexible hose with suitable material such as vinyl tape
to avoid the entry of air.

5.

Remove low-pressure pipe 1.

CAUTION:

Cap or wrap the joint of low-pressure pipe 1 and 2 with suit-
able material such as vinyl tape to avoid the entry of air.

INSTALLATION

Installation is basically the reverse order of removal.

CAUTION:

●

Replace O-rings of low-pressure pipe 1 with new ones, and then apply compressor oil to it when
installing it.

●

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.

●

When recharging refrigerant, check for leaks.
