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.
