Type I — small appliancesDifficulty 2/5

Under 40 CFR 82.152, which description matches the definition of a small appliance?

  1. AFully manufactured and charged on site with twenty pounds or less of any refrigerant
  2. BFully manufactured, charged and hermetically sealed in a factory with five pounds or less
  3. CAny self-contained unit holding five pounds or less, whether factory sealed or field charged
  4. DAny domestic refrigeration unit sold for household use regardless of its refrigerant charge
Show answer and rationale

Correct: B. All three conditions in the definition matter together: factory manufactured, factory charged, and hermetically sealed, with a charge of five pounds or less. A field-charged unit is not a small appliance however small it is.

  • C — Factory sealing is part of the definition; a field-charged unit falls outside it entirely.
  • D — The definition is about construction and charge size, not about who the unit was sold to.
  • A — Twenty pounds is the MVAC-like threshold, and on-site charging excludes a unit from the definition.
Type I — small appliancesDifficulty 3/5

Using recovery equipment manufactured in 2015 on a small appliance whose compressor no longer runs, what must you achieve?

  1. ARecover ninety percent of the charge, or evacuate to ten inches of mercury vacuum
  2. BRecover one hundred percent of the charge before the appliance may be opened at all
  3. CRecover eighty percent of the charge, or evacuate to four inches of mercury vacuum
  4. DRecover ninety percent of the charge, or evacuate to four inches of mercury vacuum
Show answer and rationale

Correct: C. Section 82.156(b)(2) makes the ninety percent figure conditional on the compressor functioning. With a dead compressor and post-1993 equipment the requirement drops to eighty percent, and the four inches of mercury option under 82.156(b)(3) remains available either way.

  • D — Ninety percent applies only when the appliance's compressor is working; this one is not.
  • A — Ten inches of mercury is a Table 1 figure for larger appliances, not a small-appliance option.
  • B — The rule never requires complete recovery; it sets percentage and vacuum thresholds instead.
Type I — small appliancesDifficulty 3/5

Why must both high and low side access valves be installed when recovering from a small appliance with an inoperative compressor?

  1. AThe recovery machine requires two connections before its internal pump will start up
  2. BRegulations require two access points on every small appliance being serviced or opened
  3. CThe second valve provides a route for nitrogen to be introduced during the recovery
  4. DNothing in the appliance can move refrigerant from one side of the system to the other
Show answer and rationale

Correct: D. A system-dependent device relies on the appliance's own compressor to shift refrigerant. With the compressor dead, refrigerant trapped on the far side of the restriction has no path out unless you open both sides.

  • A — Recovery machines do not impose a two-connection requirement of their own to operate.
  • B — The rule does not require two access points generally; the reason here is the failed compressor.
  • C — Nitrogen is a leak-detection gas and plays no part in recovering from a small appliance.
Type I — small appliancesDifficulty 2/5

What certification does a person need to dispose of a small appliance under 40 CFR 82.161?

  1. ANone, although the recovery requirements still apply to the work being carried out
  2. BType I certification, because the appliance contains a regulated refrigerant charge
  3. CUniversal certification, because disposal covers every category of appliance at once
  4. DType II certification, because disposal is treated the same as a major system repair
Show answer and rationale

Correct: A. Section 82.161(a)(1)(vii) exempts disposal of small appliances, MVACs and MVAC-like appliances from certification. The recovery obligations in 82.156(b) are separate and still bind whoever does the work.

  • B — Type I covers maintaining, servicing and repairing small appliances, not disposing of them.
  • C — Universal is not required for any single disposal task, and disposal here is expressly exempt.
  • D — Type II covers disposal of medium and higher pressure appliances, not small appliances.
Type I — small appliancesDifficulty 2/5

A technician passes a mail-in Type I test and now wants Universal certification. What is the effect of that mail-in pass?

  1. AIt counts toward Universal after a waiting period set by the certifying organisation
  2. BIt cannot be counted toward Universal, so the Type I test must be taken again proctored
  3. CIt counts toward Universal provided the remaining tests are taken under a proctor
  4. DIt counts toward Universal only if the score achieved was above eighty-four percent
Show answer and rationale

Correct: B. Appendix D states that mail-in format Type I tests cannot be used toward a Universal certification, and EPA adds that an open-book Core test cannot count either. Both must be retaken proctored.

  • C — The restriction is on the mail-in test itself, not on how the other tests are administered.
  • D — Eighty-four percent is the pass mark for a mail-in Type I; passing it still does not count.
  • A — No waiting period converts a mail-in result into one that counts toward Universal.
