Compressor Fitting HVAC: Service and Repair

A/C MANIFOLD AND TUBE ASSEMBLY REMOVAL / INSTALLATION

NOTE: Replacement of the suction accumulator is not required when repairing the air conditioning system except when there is physical evidence of system contamination from a failed A/C compressor or damage to the suction accumulator.

1. Recover the refrigerant, see A/C REFRIGERANT SYSTEM TESTS.




2. Disconnect the electrical connector.




3. Disconnect the compressor manifold and tube assembly from the A/C compressor.
1. Loosen the bolt.
2. Disconnect and position aside the compressor manifold and tube assembly,
3. Discard the O-ring seals.




4. Disconnect the manifold and tube from the receiver/drier, see A/C SPRING LOCK COUPLING.
- Discard the O-ring seals.




5. Disconnect the compressor manifold and tube assembly from the compressor to condenser discharge line and remove the compressor manifold and tube assembly.
1. Discard the O-ring seal.

6. To install, reverse the removal procedure.
- If a new compressor manifold and tube assembly is to be installed, transfer the pressure cutoff switch to the new compressor manifold and tube assembly.
- Lubricate the refrigerant system with the correct amount of clean refrigerant oil. See A/C REFRIGERANT OIL ADDITION.

7. Evacuate, leak test, and charge the refrigerant system. See A/C REFRIGERANT SYSTEM TESTS.
