A shop's office manager, who holds no technician certification, is sent to a supply house to pick up a new recovery machine for the commercial crew. What does the sales restriction require at that counter?
Correct Answer
D) Nothing, because the sales restriction covers refrigerant rather than equipment
The sales restriction is written around refrigerant. Anyone may buy a recovery machine, and the counter has no obligation to check credentials for it. Certification comes back into play when the machine is used, since only a certified technician may operate it on an appliance, and the machine itself must carry certification for the category of appliance it will serve. Buying the tool and being allowed to use it are two different questions.
Why This Is the Correct Answer
The restriction on sales applies to refrigerant, not to service equipment. A recovery machine may be purchased by anyone, and an uncertified office manager may collect it. What the regulation controls is who operates it on an appliance and whether the machine carries certification for the class of equipment it will be used on.
Why the Other Options Are Wrong
Option A: Proof that the shop employs at least one Type II certified technician
No such requirement attaches to an equipment purchase. Employment of certified technicians matters for the work, not for what the shop may buy.
Option B: Proof of certification from the person taking delivery of the machine
Certification has to be shown when refrigerant is bought, not when tools are. The counter would ask for it on a cylinder, not on a machine.
Option C: A signed statement that the machine will be used only on small appliances
Nothing is signed at purchase about how a machine will be used. The machine's own certification label states which appliance category it covers.
Memory Technique
The card is for the cylinder, not for the cart it rides on.
Reference Hint
The refrigerant sales restriction applies to refrigerant purchases; recovery equipment may be bought by anyone.
