A technician is selecting a recovery machine for an appliance using a flammable refrigerant. Which action is appropriate before connecting it?

  1. A

    Use any recovery machine if its hoses fit the appliance.

  2. B

    Confirm the machine’s certification category and specifications cover the appliance and refrigerant.

  3. C

    Select a machine based only on its gauge range.

  4. D

    Use a machine approved for a different flammability class if the cylinder is correctly rated.

Which checks should be completed before connecting recovery equipment? Select all that apply.

  1. A

    Check the machine’s power cord and switches for damage.

  2. B

    Inspect hoses, seals, and fittings for damage or leaks.

  3. C

    Rely on the machine’s automatic cutoff instead of inspecting the cylinder.

  4. D

    Verify that the cylinder is approved, serviceable, and rated for the refrigerant.

11
True or false

A technician argues that every refrigeration system has the same recovery endpoint. Which response best reflects safe recovery practice?

  1. A

    All stationary systems use one universal recovery endpoint.

  2. B

    The recovery machine’s final gauge reading establishes the endpoint for every appliance.

  3. C

    Use and verify the endpoint applicable to the appliance being serviced.

During recovery, a technician needs to track how much refrigerant has entered the cylinder. Which method is appropriate?

  1. A

    Use manifold gauges to determine how much refrigerant is in the cylinder.

  2. B

    Use a scale to monitor the cylinder’s weight during recovery.

A system’s refrigerant is unknown and may be contaminated. Which collection plan best avoids contaminating known refrigerant?

  1. A

    Put it in a cylinder containing the closest-looking known refrigerant.

  2. B

    Mix it with clean refrigerant so the cylinder remains full.

  3. C

    Use equipment and a collection cylinder intended for the unknown or contaminated material.

  4. D

    Recover it into any approved cylinder, then identify it later.

You are setting up a recovery cylinder before connecting the equipment. Which procedure best supports safe handling and fill monitoring?

  1. A

    Lay the cylinder on its side and rely on the machine’s automatic shutoff.

  2. B

    Secure it upright on the scale, note its starting weight, and protect it from heat.

  3. C

    Place it near a heat source so pressure remains stable during recovery.

  4. D

    Keep it upright but off the scale until recovery is complete.
