A commercial refrigeration appliance has a 30-pound charge containing an HFC blend, and refrigerant has been added repeatedly. Which approach correctly determines whether federal leak-repair requirements apply?

  1. A

    Because the charge is below 50 pounds, conclude that neither federal leak-repair program can apply.

  2. B

    Identify the refrigerant composition and full charge; for Section 608, check whether it is an ozone-depleting refrigerant and whether the charge and applicable leak-rate trigger conditions are met. For the AIM Act ER&R rule, check whether the refrigerant contains an HFC or covered substitute with a GWP above 53, whether the appliance category is covered or excluded, and, if covered, calculate the leak rate and compare it with the applicable threshold.

  3. C

    Apply Section 608’s ozone-depleting-refrigerant requirements automatically to every HFC blend, without checking the appliance category or leak rate.

  4. D

    Assume the appliance is covered by the AIM Act ER&R rule only if it is residential air conditioning; do not evaluate its refrigerant composition or leak rate.

A leak prevents a high-pressure appliance from reaching its listed evacuation level. Which actions are consistent with the limited leaking-equipment exception? Select all that apply.

  1. A

    Isolate leaking from non-leaking components wherever possible

  2. B

    Leave non-leaking sections unevacuated because one section is leaking

  3. C

    Evacuate non-leaking sections to their applicable level

  4. D

    Reduce the leaking section to the lowest achievable level that does not substantially contaminate recovered refrigerant, and do not leave it above 0 psig

  5. E

    Treat 0 psig as the normal target for every appliance

    Refrigerant identity and quantities recovered and added

  2. B

    Repair actions and test results

  3. C

    Only the technician's preferred recovery method, with no equipment results

  4. D

    Equipment status, operating checks, and required owner notifications

  2. B

    Compressed air, provided the system is isolated

  3. C

    Regulated dry nitrogen, where the approved procedure permits it

  2. B

    Do not change the oil while pressure is above 5 psig

  3. C

    Change the oil only after reaching 0 inches Hg vacuum

A high-pressure appliance has a 240-pound charge, but its manufacture date is unknown. Before selecting the normal evacuation target for opening the circuit, what should the technician do?

  1. A

    Use 0 psig as the universal recovery target

  2. B

    Choose either 4 or 10 inches Hg vacuum based only on the refrigerant blend

  3. C

    Determine the manufacture date and use the corresponding EPA table target

  4. D

A leak appears repaired before charging, but a later check shows that it persists. What is the appropriate response before treating the repair as complete?

  1. A

    Reassess the leak and repair, correct the defect, and repeat the applicable verification tests

  2. B

    Treat the repair as complete because the leak appeared to stop before charging

  3. C

    Return the appliance to service and omit the failed check from the records

  4. D

    Rely on a pressure or vacuum decay result even if it does not locate a leak
