A contractor is buying a recovery machine that will be used on high-pressure commercial equipment. What does the rule require of that machine?
Correct Answer
B) That it be equipment certified as meeting the recognized performance standard for recovery devices
Recovery and recycling equipment used on this kind of work has to be certified against the recognized performance standard, which sets how deeply and how quickly a machine must be able to pull a system down. The certification is on the equipment model, and machines carry a label showing it. There is no mandatory rebuild interval, no DOT stamp on a machine, and no requirement to dedicate a machine to a single refrigerant, although good practice is to flush the machine between refrigerants and keep separate hoses so charges do not get cross-contaminated.
Why This Is the Correct Answer
Recovery equipment must be certified to the recognized performance standard, which is how the rules guarantee that a machine can actually achieve the required recovery levels. Manufacturers submit machines for testing and the approved models carry a label the technician can point to during an inspection.
Why the Other Options Are Wrong
Option A: That it be returned to the original manufacturer every three years for a factory rebuild and recertification
No rebuild interval appears in the rule. Machines need oil and filter changes on the manufacturer's schedule, but that is maintenance guidance and carries no recertification clock.
Option C: That it carry a Department of Transportation stamp like the recovery cylinders it fills
Department of Transportation stamps belong on pressure vessels such as cylinders. A recovery machine is not a shipping container, and it carries an equipment certification label instead.
Option D: That it be dedicated to a single refrigerant for the whole of its working service life
Machines are routinely used across several refrigerants. Good practice is to clear the machine between refrigerants and keep separate hoses, not to buy a dedicated machine for each one.
Memory Technique
Tech gets a card, machine gets a label, cylinder gets a stamp. Three different pieces of paper.
Reference Hint
40 CFR 82.158 requires recovery and recycling equipment to be certified to the applicable performance standard; cylinders are separately DOT approved.
