The question

What do the regulation and EPA guidance say a technician must do to be sure the right amount of refrigerant is recovered?

• ARun the recovery unit for at least one hour
• BUse the equipment as its manufacturer directsCorrect answer
• CRecover until frost forms on the suction line
• DAsk the appliance owner to confirm the charge

Why “Use the equipment as its manufacturer directs” is correct

Section 82.156(g) requires all recovery equipment to be used in accordance with the manufacturer's directions, and EPA's service practice page says this ensures the correct level is recovered. Small-appliance equipment is certified under 82.158(e) based on use under those instructions.

Why the other answers are wrong

• Run the recovery unit for at least one hour — There is no fixed run time; equipment is used as its manufacturer directs.
• Recover until frost forms on the suction line — Frost is not the measure of proper recovery.
• Ask the appliance owner to confirm the charge — The owner's word does not show that recovery is complete.
