System-dependent recovery equipment may be used only on appliances that normally hold up to what amount of refrigerant?
Correct Answer
C) Appliances that normally hold fifteen pounds or less
System-dependent recovery equipment has no pump of its own; it leans on the appliance's compressor and internal pressure to move refrigerant into a container. That works on very small systems and becomes impractical and unreliable on larger ones, so the rules cap its use at appliances normally containing fifteen pounds of refrigerant or less. Anything above that has to be recovered with self-contained equipment that can pull the charge out under its own power.
Why This Is the Correct Answer
The regulation limits passive, system-dependent recovery to appliances that normally contain fifteen pounds of refrigerant or less. Above that threshold the technician must switch to self-contained equipment, because relying on the appliance's own pressure cannot reliably meet the required recovery levels on larger charges.
Why the Other Options Are Wrong
Option A: Appliances that normally hold five pounds or less
Five pounds is the ceiling in the small appliance definition, not the ceiling for system-dependent equipment. The two limits are different numbers answering different questions.
Option B: Appliances that normally hold ten pounds or less
Ten pounds does not appear in the recovery equipment rules. It sits between the two real thresholds and is there to catch a hazy memory.
Option D: Appliances that normally hold fifty pounds or less
Fifty pounds is associated with recordkeeping and leak repair thresholds for larger appliances, not with the use of passive recovery equipment on small systems.
Memory Technique
The passive kit borrows power from the system, and it can only borrow so much: fifteen pounds is where its credit runs out.
Reference Hint
40 CFR 82.156(g): system-dependent recovery equipment shall not be used on appliances normally containing more than fifteen pounds of refrigerant.
