HIGH-PRESSURE PIPE

Removal and Installation

INFOID:0000000009269758

CAUTION:

Perform oil return operation before each refrigeration system disassembly. However, if a large amount

of refrigerant or oil is detected, do not perform oil return operation. Refer to

HA-21, "Perform Oil

Return Operation"

.

REMOVAL

1. Remove low-pressure flexible hose. Refer to

HA-33, "Removal and Installation"

.

2. Disconnect high-pressure pipe from expansion valve.

CAUTION:

Cap or wrap the joint of the A/C piping and expansion valve with suitable material such as vinyl

tape to avoid the entry of air.

3. Remove high-pressure pipe bolt and disconnect high-pressure pipe from the condenser.

CAUTION:

Cap or wrap the joint of the A/C piping and condenser with suitable material such as vinyl tape to

avoid the entry of air.

4. Loosen the clip and remove high-pressure pipe from the vehicle.

INSTALLATION

Installation is in the reverse order of removal.

CAUTION:

• Do not reuse O-rings.

• Apply A/C oil to the O-ring of the high-pressure pipe for installation.

• After charging the A/C refrigerant, check for leaks. Refer to

HA-17, "Leak Test"

.
