4.
Pull engine room insulator, then remove pipes bracket fixing
bolt, from expansion valve, then release pipe fixing bracket from
high pressure pipe 1, to disconnect it from expansion valve.
CAUTION:
Cap or wrap the joint of the high pressure pipe 1, and
expansion valve in, with suitable material such as vinyl tape
to avoid the entry of air.
5.
Remove high pressure pipe 1 (1) from clip (A).
• Remove high-pressure pipe 1 mounting bolt (A) from con-
denser (2).
• Remove high pressure pipe 1 (1).
CAUTION:
Cap or wrap the joint of the high pressure pipe 1, and con-
denser, 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 of high-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.
