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 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.
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".
