Which step best describes a complete refrigerant recovery action from a serviced system?

• A. Attach a certified recovery machine to service ports, evacuate to required vacuum levels, capture refrigerant to a recovery cylinder, and document
• B. Open the system to atmosphere
• C. Purge with dry nitrogen and vent to atmosphere
• D. Dispose of refrigerant without recovery

Answer: (A)

Complete refrigerant recovery hinges on using a certified recovery machine to remove the refrigerant from the system, pulling it to the required vacuum level, capturing it in a recovery cylinder, and documenting the process. This sequence ensures the refrigerant is safely contained and not vented to the atmosphere, meets regulatory requirements, and provides a traceable record for compliance. Opening the system to the atmosphere, purging with dry nitrogen and venting, or disposing of refrigerant without recovery would release or waste the refrigerant and violate environmental rules, making them unsuitable.
