For other high pressure appliance or isolated component normally containing less than 200 pounds of refrigerant, what was the required recovery level after November 15, 1993?

Vacuum level during refrigerant recovery is what this rule focuses on. After November 15, 1993, for high‑pressure appliances or isolated components that normally contain less than 200 pounds of refrigerant, the required recovery level is to pull a vacuum of at least 10 inches of mercury. In other words, you continue the recovery until the system shows about a 10 inHg vacuum, indicating most of the refrigerant has been removed and the risk of release is minimized. The other numbers don’t meet this specific regulatory threshold for this category and date: 0 inHg means no vacuum, 4 inHg is below the minimum, and 15 inHg exceeds the minimum but isn’t the specified requirement.
