May it be used on small appliances?

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 owns a recovery unit built in 1991 that was never tested by an equipment testing organization. May it be used on small appliances?

• AYes, if it can recover 80 percent or reach a 4-inch vacuumCorrect answer
• BNo, every recovery unit must carry a testing lab's certification
• CYes, with no performance standard at all
• DOnly for disposal work, never for service

Why “Yes, if it can recover 80 percent or reach a 4-inch vacuum” is correct

Under 82.158(e)(1), equipment made before November 15, 1993 is considered certified if it can recover 80 percent of the refrigerant, whether or not the test-stand compressor runs, or reach a four-inch vacuum on a calibrated gauge.

Why the other answers are wrong

• No, every recovery unit must carry a testing lab's certification — Pre-November 15, 1993 equipment is considered certified if it meets the performance level, without lab testing.
• Yes, with no performance standard at all — Older equipment still has to be capable of 80 percent recovery or a 4-inch vacuum.
• Only for disposal work, never for service — The rule does not limit grandfathered equipment to disposal.
