HIGH-PRESSURE FLEXIBLE HOSE

6.

Remove high pressure flexible hose fixing bolt (1) from con-
denser (3), then pull high pressure flexible hose (2) to remove it
from condenser.

CAUTION:

Cap or wrap the joint of high-pressure flexible hose and
condenser assembly with suitable material such as vinyl
tape to avoid the entry of air.

7.

Remove high pressure flexible hose fixing nut (A) from compres-
sor, then pull high pressure flexible hose (1) to remove it from
compressor. Remove high pressure flexible hose.

CAUTION:

Cap or wrap the joint of compressor and high-pressure flex-
ible 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 high-pressure flexible hose 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.
