When filling a charging cylinder with a regulated refrigerant, what must be recovered?

When you fill a charging cylinder with regulated refrigerant, the liquid entering the cylinder pushes out some of the gas that’s already in the headspace. That vapor needs to be captured because releasing refrigerant gas to the atmosphere is regulated and not allowed for these substances. The recovery system gathers that vented vapor so it can be reclaimed or safely disposed of, rather than letting it escape. Venting the gas to the atmosphere is not permitted for regulated refrigerants, and simply recovering only the liquid doesn’t address the gas that’s being displaced. The requirement focuses on capturing the vapor that vents from the top of the cylinder during charging.
