High-pressure flexible hose : Removal and Installation

CAUTION:
Perform lubricant return operation before each refrigeration system disassembly. However, if a large amount of refrigerant or lubricant is detected, never perform lubricant return operation. Refer to HA- 23, "Perform Lubricant Return Operation

".

REMOVAL

1. Use a refrigerant collecting equipment (for HFC-134a) to discharge the refrigerant. Refer to HA-21, "Recycle Refrigerant".

2. Remove mounting bolt (A), and then disconnect high-pressure flexible hose from 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.

3. Remove mounting bolt (A), and then disconnect high-pressure


3. Remove mounting bolt (A), and then disconnect high-pressure flexible hose from compressor.

CAUTION:
Cap or wrap the joint of the A/C piping and compressor with suitable material such as vinyl tape to avoid the entry of air.

4. Remove high-pressure flexible hose from vehicle.


4. Remove high-pressure flexible hose from vehicle.

INSTALLATION

Note the following items, and then install in the reverse order of removal.

CAUTION:
• Replace O-rings with new ones. Then apply compressor oil to them when installing.

• Check for leakages when recharging refrigerant. Refer to HA-19, "Leak Test".
