    I was out of town 5 hr drive to go get 12 - I should have had enough but I didn't - farmers dog tucker cooler ( or freezer ) I don't remember - repaired leak woulda caught hell if I had to go get 12 - I finished it off with 502 a bout a 1lb of 502 to 12 lbs 12

    never heard a thing ( I figured 502 was partly 12 anyways )

    I'm a little confused...if you put r-22 in a r-404a system, whether the capacity be 8 lbs (and you add 3lbs), 200 lbs (and you add 60 lbs), or 1000 lbs (and you add 100 lbs), wouldn't you have to adjust the txv's or anything? Since the boiling points, etc. of both refrigerants ARE slightly different?

    Out of all the dumb threads on this forum, this one is up there with the worst.
    If more government is the answer, then it's a really stupid question.

    I hope I never run into a situation where mixing refrigerants is required. I recently started servicing cooler/freezers/AC, and only had to repair r22 AC so far, but the guy that did it before didn't seem real big on labeling, I've found notes written in marker with 239,r404/408 etc written on equipment, sometimes the same equipment...

    R239 that's a new one to me. Must be what you get when you mix
