REFRIGERANT PRESSURE SENSOR : 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. See: Heating and Air Conditioning/Refrigerant Oil/Service and Repair/Perform
Lubricant Return Operation.
REMOVAL
1. Use a refrigerant collecting equipment (for HFC-134a) to discharge the refrigerant. See: Heating and Air Conditioning/Refrigerant/Service and
Repair/Recycle Refrigerant.
2. Clean refrigerant pressure sensor and its surrounding area, and then remove dust and rust from refrigerant pressure sensor.
CAUTION:
Be sure to clean carefully.
3. Disconnect refrigerant pressure sensor connector.
4. Use a adjustable wrench (A) or other tool to hold the refrigerant pressure sensor mounting block, and then remove the refrigerant pressure sensor
(2) from the condenser (1).
CAUTION:
-
Be careful not to damage liquid tank.
-
Be careful not to damage core surface of condenser.
-
Cap or wrap the joint of the condenser and liquid tank 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-ring with new one. Then apply compressor oil to them when installing.
-
Check for leakages when recharging refrigerant. See: Heating and Air Conditioning/Refrigerant/Service and Repair/Leak Test.
