What is the evacuation level required for a high-pressure appliance containing less than 200 lbs of HCFC or HFC refrigerant?

• A. 10 inches of vacuum
• B. 5 inches of vacuum
• C. 0 inches of vacuum
• D. 15 inches of vacuum

Answer: (C)

For high-pressure appliances that contain less than 200 lbs of HCFC or HFC refrigerants, the evacuation level is designated as 0 inches of vacuum. This means that the refrigerant can be removed without needing to create a vacuum within the system. The EPA regulations are specific about the evacuation requirements, particularly for high-pressure systems, where it is recognized that complete evacuation to a significant vacuum level is not necessary when the amount of refrigerant is below a certain threshold. In practice, achieving a vacuum is typically more pertinent to specific recovery scenarios, particularly those involving low-pressure systems or possibly larger quantities of refrigerants where modifications might affect residual gas. However, for appliances with less than 200 lbs of refrigerant, simply recovering the refrigerant as specified requires no additional vacuum, thus setting the evacuation level at 0 inches. Understanding this standard is critical for ensuring compliance with EPA regulations and performing safe refrigerant recovery practices within the industry.
