R-22 Recovery Procedure Question

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!

blutfort, All you need to do is stick the bottle in in a bucket of warm water, I guarantee you will get most of that last lb out

RE: R-22 Recovery Procedure Question

EPA-wise, your only requirement is to not discharge it to the atmosphere.

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.
