R-22 Recovery Procedure Question
R-22 Recovery Procedure Question
(OP)
While I am certified, all that means is I took the test and passed. I have a question regarding EPA regulations on recovery processes.
1. Assume I have a type II machine and recovered 20 lbs. of R-22 into a recovery cylinder.
2. I perform maintenance on the machine.
3. I evacuate the machine.
4. I charge the machine from the recovery cylinder, but I am only able to get 19 lbs out of the cylinder. The other 1 lb is now vapor.
What is my requirement for the remaining 1 lb?
Thanks in advance!

Since most recovery machines can pull a vacuum, common practice these days seems to be to consolidate many such cylinders into one cylinder, and send to a recycler. If you are servicing a single client, and you are confident it is clean, you can reuse.
