Final answer:
A recovery device made after November 15, 1993 must have the capability to recover refrigerants even if the compressor is not working, using alternative methods such as a secondary compressor or a self-contained power source.
Step-by-step explanation:
A recovery device made after November 15, 1993 must be capable of recovering refrigerants from a system even if the compressor is not working. This is necessary to safely remove and handle the refrigerants without releasing them into the environment.
To recover refrigerants from a system when the compressor is not working, the recovery device must rely on alternative methods such as using a secondary compressor or a self-contained power source. These methods ensure that the refrigerants are properly collected and stored.
Additionally, the recovery device must meet the regulations set by organizations such as the Environmental Protection Agency (EPA) to ensure proper handling and disposal of the recovered refrigerants.
