LOW-PRESSURE FLEXIBLE HOSE AND PIPE 2

5.

Remove mounting bolt (A) from low-pressure flexible hose
bracket (1).

6.

Disconnect the one-touch joint between low-pressure pipe 1 (1)
and low-pressure pipe 2 (2) with disconnector (A) (SST:
9253089916).

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.

7.

Disconnect the one-touch joint between low-pressure pipe 2 (1)
and low-pressure flexible hose (2) with disconnector (A) (SST:
9253089916).

CAUTION:

Cap or wrap the joint of low-pressure pipe 2 and low-pres-
sure flexible hose with suitable material such as vinyl tape
to avoid the entry of air.

8.

Remove the low-pressure pipe 2 clip (B).

9.

Remove low-pressure pipe 2.

10. Remove mounting nut (A) from 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.

11. Remove low-pressure flexible hose.

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

does not come loose.

• When recharging refrigerant, check for leaks.
