A/C System R-134A Recovery

^ Before removing or replacing any of the AC refrigerant lines or components, the refrigerant must be completely recovered.

NOTE: Verifying the purity of the refrigerant with a refrigerant purity identifier before recovery is recommended.

^ The refrigerant system must be discharged using an air conditioning refrigerant recovery and recycling system. Follow the manufacturer's operating instruction for system being used.

NOTE: The air conditioning refrigerant and recycling station must meet UL standards for moisture and contamination removal. Recovery systems which cannot meet these standards are not approved for warranty repairs. Reuse of moisture or particulate contaminated refrigerant will result in premature compressor and other component failure.

^ Always check the A/C system for pressure with a manifold gauge set to determine if refrigerant is present in the system. Performing recovery on an A/C system which is open to atmosphere as a result of a leak, would allow the recovery station to pull only air into the tank.

NOTE: Failure to check for residual oil from the previous recovery can result in adding extra oil to the vehicle currently being serviced. This will also result in insufficient oil in the system previously worked on and could possibly contribute to premature compressor failure.
