    Wouldn't hurt to cut a couple of strategically located ball valves in while you've got the high side empty. Save your self all this hassle next time.

    You won't have to go through the same procedure again.............because you're going to sweat in a couple of ball valves and pressure taps while the rack is down.

    i would bring in another tech to help, you don't have three hours to clean and then pipe in these valves unless you done this a bunch it will take some time and if something goes wrong there is 2 heads
    once you think you've seen it all
    (THINK AGAIN)
    I would rather work for free than be look upon as a thief!!!!!

    Just ahead of that separator there should be a check valve. I'd verify that it checks. Then, even if that check seeps out a hair, so what, pull that separator apart and have a look.

    If you do end up having to recover that run you isolate, no big deal. I would for sure come preped with a ball valve and cut it in for isolation..

    Let us hear about how she goes when you get done.

Finally shut the inlet to the condensor, and dump the remaining discharge gas back into the systems you pumped down when you started. I would have new float in hand because you don't need to repete this if there is a problem.
    good tips. good tips. these are those tips that you can only pick up by having another guy explain them to you.

    I do this alot. now a days. Back when I was green I learned it from someone. It never occured to me before that.
