Question

When R-500 is recovered from an appliance, what must be done with it?

1) It can be mixed with either R-22 or R-12 during the recovery process, since R-500 is actually a mixture of the two refrigerants
2) It can be mixed with R-12 but not R-22 during the recovery process
3) It need not be recovered since R-500 is not one of the refrigerants covered by the Clean Air Act
4) It must be recovered into its own recovery vessel that is clearly marked to ensure that mixing of refrigerants does not occur

Answer 1

R-500 must be recovered into its own, clearly marked recovery vessel to prevent the mixing of refrigerants and to adhere to the Clean Air Act regulations.

Step-by-step explanation:

When R-500 is recovered from an appliance, it must be recovered into its own recovery vessel that is clearly marked to ensure that mixing of refrigerants does not occur. This is essential to prevent contamination of refrigerants and to comply with regulations regarding the handling of such substances. The Clean Air Act regulates the recovery, recycling, and reclaiming of refrigerants, and it specifies that different types of refrigerants should not be mixed because this can make them impossible to reuse and can lead to equipment damage or unsafe conditions.
