A technician plans to use system-dependent recovery equipment on an appliance with a 12-pound full charge. The equipment is not permanently attached as a pump-out unit. Is this use permitted?

  1. A

    No; system-dependent equipment is never allowed on small appliances.

  2. B

    Yes; its full charge is within the 15-pound limit.

  3. C

    No; the limit is 10 pounds unless the appliance has a functioning compressor.

  4. D

    Yes, but only if the appliance is permanently attached to the recovery device.

A small appliance’s compressor functions, and a technician is using system-dependent recovery equipment. What should the technician do to help move refrigerant?

  1. A

    Operate the compressor to help move refrigerant.

  2. B

    Disable the compressor so the device can move refrigerant independently.

  3. C

    Open the refrigerant circuit and allow pressure to release before recovery.

  4. D

    Use only a self-contained recovery device, because system-dependent equipment cannot be used with a functioning compressor.

A small appliance’s compressor is inoperative, and a technician is using system-dependent recovery equipment. Which two actions are appropriate recovery techniques?

  1. A

    Provide access to both the high and low sides.

  2. B

    Recover only from the low side because refrigerant cannot remain on the high side.

  3. C

    Consider warming the appliance to encourage refrigerant movement, when appropriate.

  4. D

    Release refrigerant from the high side to reduce pressure before recovery.

Select all statements that accurately describe small-appliance recovery-device designs.

  1. A

    Self-contained equipment has its own means of moving refrigerant into a recovery container.

  2. B

    Self-contained equipment relies on the appliance’s compressor to move refrigerant.

  3. C

    System-dependent equipment relies on the appliance’s compressor or system pressure to move refrigerant.

  4. D

    System-dependent equipment always has its own means of moving refrigerant, independent of the appliance.

After servicing a sealed small-appliance system, when should a technician check for leaks in relation to charging or recharging?

  1. A

    Check for leaks only after the appliance has been charged.

  2. B

    Check for leaks only if the appliance uses a system-dependent recovery device.

  3. C

    Check for leaks before charging or recharging.
