    EPA 608 Type I Practice Questions — Small Appliance Certification

    Type I certification covers small appliances — units with a refrigerant charge of 5 lbs or less. These free practice questions test recovery methods, evacuation requirements, the appropriate recovery equipment for hermetically-sealed systems, and the specific leak-repair exemptions that apply to small appliances. Every answer cites the relevant 40 CFR section.

    Sample questions

    1. A "small appliance" under Section 608 is defined as one with a refrigerant charge of:

    1. A. ≤ 1 lb
    2. B. ≤ 5 lb
    3. C. ≤ 25 lb
    4. D. ≤ 50 lb
    Show explanation

    EPA defines a small appliance as a hermetically sealed unit with ≤ 5 lb of refrigerant — household refrigerators, freezers, room A/C units, water coolers, dehumidifiers, vending machines.

    Ref: 40 CFR §82.152

    2. Required recovery level for small appliances when using recovery equipment manufactured AFTER November 15, 1993:

    1. A. 50% of the charge or 0 psig, whichever is greater
    2. B. 80% of the charge or 4 in Hg vacuum, whichever is less restrictive
    3. C. 90% of the charge if compressor operating, 80% if not
    4. D. Full atmospheric pressure
    Show explanation

    Post-1993 recovery equipment on small appliances must achieve 90% recovery if the compressor is operating, 80% if it is inoperative (or pull the system to 4 in Hg vacuum).

    Ref: 40 CFR §82.158

    3. When recovering refrigerant from a sealed system whose compressor is inoperative, the technician should:

    1. A. Run the compressor anyway to speed recovery
    2. B. Use system access piercing valves on suction and discharge lines and recover from both
    3. C. Vent the system to atmosphere since recovery is impractical
    4. D. Cut the lines open with a tubing cutter
    Show explanation

    With an inoperative compressor the refrigerant cannot be circulated, so the technician installs piercing access valves on both the high and low side and recovers from both ports.

    Frequently asked

    What counts as a "small appliance" under Type I?

    Refrigeration and AC equipment manufactured, charged, and hermetically sealed with 5 lbs or less of refrigerant — household refrigerators, room ACs, packaged terminal AC, water coolers.

    What recovery efficiency does Type I require?

    Recovery equipment manufactured after 11/15/93 must achieve 80% of the refrigerant or 4" Hg vacuum when the appliance is operating, or 4" Hg vacuum when the compressor is not running.
