    Got one like that.
    It threw one of our techs off when he tried to reuse what he pumped into it.

    One of the guys that helped train me, was an older chiller tech.....he said, "ALWAYS check to make sure the valves actually are correct before charging!!" He had a BAD experience with a chiller because of that.

    Here's what happened today.

    Leak check and repair. Two stage, maybe a 10 ton package unit, tonnage matters little here. Found leak, recovered, repaired, then went to do the leak check. I always use the vapor off of the top of the recovered refer and charge to 15 psig. Then top up with nitro to 150 psig.

    Just that today I saw the high side hose jumping as though it had liquid going through it. Wasn't too concerned. Then it hit me, something was wrong. I shut all the valves as fast as I could. Then just stood there. Trying to figure out what I did wrong.

    Then saw the labeling on the handles. I'm like, crap. Well, at least there is so much R-22 in the system. Don't need no freakin' nitro for leak checking. Kinda sorta pissed me off; is this tank from Mexico, China, or Tennessee??

    You'd likely still need higher pressure to show all leaks. You might have put a pound or so into it. I would have thrown nitrogen on top and went with it.

    I may put 5 lbs in a 1,000 ton chiller, plus nitrogen pressure.

    I don't believe there is an actual percentage listed for "trace gas" In the EPA ruling.

    My rule is 10% trace gas. Then nitro up to 150 psig. The H-10G is an awesome piece of equipment.

    With R-22, and 90% R-22, repairing a known leak, 25 psig would probably do it.

    Kind of a sad story, just today, got a call . . . Ooops, open forum . . .
