The question
Why should a technician confirm which refrigerant is in a small appliance before recovering it?
- To decide whether the unit counts as a small appliance
- To set the appliance thermostat correctly
- To choose between 80 and 90 percent recovery
- To keep different refrigerants out of the same containerCorrect answer
Why “To keep different refrigerants out of the same container” is correct
Mixed refrigerants are hard or impossible to reclaim. Using pressure and temperature, plus the nameplate, to identify the refrigerant first lets the technician keep each type in its own recovery container.

Why the other answers are wrong
- To decide whether the unit counts as a small appliance — The small-appliance definition depends on factory sealing and a charge of 5 pounds or less, not on which refrigerant is inside.
- To set the appliance thermostat correctly — The thermostat has nothing to do with recovery.
- To choose between 80 and 90 percent recovery — The level depends on equipment age and compressor condition, not the refrigerant.
