A shop acquires a used recovery machine with no documentation. What should be confirmed before it is put to work on small appliances?
Correct Answer
B) The machine's date of manufacture and whether that model was certified by an EPA-approved laboratory
Two facts decide whether a used machine may be used and what standard it commits the shop to. The manufacture date tells you which side of November 15, 1993 it falls on, and for machines built on or after that date the model has to have been certified by an EPA-approved laboratory. Both are usually found on the data plate or by looking the model up with the manufacturer. Hose length, prior refrigerant history, and the seller's own credentials are not the issue.
Why This Is the Correct Answer
The date plate and the model's certification status are what determine whether the machine is usable and which recovery level applies. Equipment made on or after November 15, 1993 must be a laboratory-certified model, while older equipment is grandfathered at the lower percentage, so the shop needs to know which it bought.
Why the Other Options Are Wrong
Option A: That the machine's hoses are shorter than six feet in order to limit trapped refrigerant
Hose length is not regulated. Trapped refrigerant in hoses is addressed with low-loss fittings and by clearing the machine, not by a length limit.
Option C: That the previous owner's certification records were transferred along with the machine
Technician certification belongs to individuals and does not attach to equipment. Nothing about the previous owner's credentials transfers with a machine.
Option D: That the machine has never been used with a refrigerant other than the one now planned
Prior refrigerant history matters only in that the machine should be cleared before use. It has no bearing on whether the machine is legal to operate.
Memory Technique
Ask a used machine two questions: when were you born, and who signed off on you.
Reference Hint
40 CFR 82.158 recovery equipment certification by an EPA-approved laboratory for equipment manufactured on or after November 15, 1993.
