sion valve.

CAUTION:

Cap or wrap the joint of the low pressure then remove fixing
bolt (3) pipe 2, and expansion valve exit with suitable mate-
rial such as vinyl tape to avoid the entry of air.

Remove low pressure flexible hose fixing nut (A), from air condi-
tioner compressor, and remove low pressure flexible hose (1).

CAUTION:

Cap or wrap the joint of low-pressure flexible hose 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 low-pressure flexible hose and low-pressure pipe 2 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
