What share of the refrigerant must be recovered?

Recovery requirements · EPA 608 Type I. The correct answer, and the reasoning behind it.

The small-appliance definition and the recovery levels required.

The question

A technician uses recovery equipment built in 2012 on a household refrigerator whose compressor runs. What share of the refrigerant must be recovered?

• A80 percent
• B90 percentCorrect answer
• C100 percent
• D85 percent

Why “90 percent” is correct

With equipment made on or after November 15, 1993, the level is 90 percent when the appliance compressor is functioning. A working compressor helps push refrigerant out, so EPA expects more of it to be recovered.

Why the other answers are wrong

• 80 percent — Eighty percent applies to newer equipment only when the appliance compressor is not working.
• 100 percent — The regulation does not require every last bit of refrigerant from a small appliance.
• 85 percent — No small-appliance recovery level is set at 85 percent.
