If R-502, which is a mixture comprised of 48.8% R-22 and 51.2% R-115, is recovered from a refrigeration system, it must be placed in a recovery tank containing which refrigerant?

🔍 Key Concepts

• Refrigerant recovery and recycling rules about mixing or separating refrigerants • The fact that R-502 is a specific blend (48.8% R-22 and 51.2% R-115) designed to work as a mixture, not as separate components • Contamination risks when putting a blended refrigerant into a tank that already contains a single, pure refrigerant

💭 Think About

• Ask yourself: when you recover a blended refrigerant, are you allowed to mix it with a tank that holds only one of its components, or does that create a contaminated mixture? • Consider what happens to the quality and re‑usability of the refrigerant if you put a known blend into a cylinder that contains only R‑22 or only R‑115. • Think about how recovery cylinders are usually labeled: do they specify a single refrigerant, or the exact blend that’s inside?

✅ Before You Answer

• Verify whether recovery cylinders are supposed to contain only one specific refrigerant or blend type. • Check whether adding a refrigerant blend to a cylinder that already contains a single-component refrigerant would be considered contamination. • Confirm how R‑502 is labeled and handled: as its own refrigerant or as two separate refrigerants.
