Multiple Choice

Before beginning a refrigerant recovery procedure, what is ALWAYS necessary to determine?

Determining the refrigerant type before starting recovery is essential because the recovery process, equipment settings, and safety/regulatory requirements depend on which refrigerant is in the system. Different refrigerants require different recovery cylinders, oils, pressures, and procedures, and mixing refrigerants or using the wrong method can contaminate the system and violate environmental laws. The refrigerant is usually identified on the appliance label or system nameplate, so you know exactly what you’re recovering and how to configure the recovery equipment accordingly. Other steps like checking for leaks, evacuating after recovery, or replacing components are important parts of service, but they don’t replace the need to know the refrigerant type first.
