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?
- AProof 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.
- BProof 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.
- CA 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.
- Nothing, because the sales restriction covers refrigerant rather than equipment
Why D is correct
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.
What this question is testing
This tests the exact scope of the sales restriction, which candidates routinely over-apply to anything sold at a supply house. Knowing what a rule does not cover is as testable as knowing what it does.
On the job
This comes up whenever a shop sends whoever is free to collect equipment, and the counter staff sometimes ask for a card out of habit. The distinction worth carrying is that three separate certifications exist in this program: the technician, the recovery equipment, and in the case of refrigerant, the purchaser. They are checked at different moments and by different people.
Memory technique
The card is for the cylinder, not for the cart it rides on.
Exam tip
The sales restriction follows the refrigerant. Machines, gauges and cylinders are not what it was written about.
Where to look it up
The refrigerant sales restriction applies to refrigerant purchases; recovery equipment may be bought by anyone.
