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- 78, "Perform Lubricant Return Operation".

REMOVAL

1. Use a refrigerant collecting equipment (for HFC-134a) to discharge the refrigerant. Refer to HA-76, "Recycle Refrigerant".

2. Remove front bumper fascia assembly. Refer to EXT-13, "Removal and Installation".

3. 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.
