What is the post-November 15, 1993 recovery level for non-HCFC22 more than 200 lbs?

The post-November 15, 1993 recovery level for refrigerants, other than HCFC-22, that weigh more than 200 pounds is indeed 15 inches of mercury vacuum. This standard was established as part of regulatory requirements aimed at ensuring proper handling and recovery of refrigerants to minimize environmental impacts, particularly those substances that contribute to ozone depletion and global warming.

The definition of the recovery level specifies the amount of vacuum that must be achieved during refrigerant recovery processes. For heavier refrigerants, such as those greater than 200 lbs, the required vacuum level reflects the practice of ensuring that any residual refrigerant is effectively drawn from the system to prevent its emission into the atmosphere.

Understanding the history and the importance of these recovery levels is crucial for compliance with EPA regulations. These standards have been implemented to protect the environment and promote safe practices in refrigeration and air conditioning maintenance. The specified vacuum level of 15 inches of mercury after recovery helps technicians to properly manage and dispose of refrigerants in a manner consistent with legal and environmental standards.
