Not quite. The answer is B: A recovery method that uses the appliance's own functioning compressor as part of the process of moving refrigerant into a recovery container
System-dependent recovery leans on the appliance's own compressor to do the work of pumping refrigerant out — it's a simpler, often faster approach when the compressor is confirmed to be running, but it only works at all if that compressor is functional. That dependency is exactly what gives the method its name.

Checked against the official text
Read the eCFR text current through 2026-10-30 of § 82.152. Definition: equipment that requires the assistance of components contained in the appliance. § 82.156(e) also bars system-dependent equipment on appliances over 15 lb unless it is a permanently attached pump-out unit.
