    Are you sure it's supposed to have 22 in it?

    I know it's a dumb question , but those pressures are cooky.

    That "check valve" might be a C.R.O.???? I don't know what you are seeing.

    Maybe you should have "502" type refrigerant in there.(404 , 502 , 408 , or something else )

    Maybe it's one of those pesky Hussmann "Heat Eradicators" from back in the 70s........

    Seriously though phil, we need some model numbers, pics (hopefully) or something more to allow us to help you with this one.

    We're ready when you are.

    Wink

    I dont think you have two acumator on your unit. the other one is called receiver. the check valve your talking about is the bypass for low ambient control. if you say your unit takes 26lbs of 22 you just put in 15lbs and your head pressure that high. then that ambient control is by passing. its bad now you need to determine if its a head master (looks like a big expansion valve) or ORD-OIR I think you have this one look like check valve. there is two parts of this control one may look like an L shape. make sure you put the right one back because those parts works together. the bad news is you got to recover everthing and start over. dont forget the drier this time.

    I've seen a ton of these.

    That extra valve up there near the condensor is a headmaster. It's possibly bad and that's why she's not drinking all that gas your trying to injest in here.

    They are rock solid systems. Three coils with ton vales on each.

    You might want to change the oil in the compressor while your up there. No one ever does.

    Oh, yeah, Phil?

    Do you have any friends that are commercial refirgeration techs that might be able to take a look at that with you?

    Those pressures are really way out of this world.

    thanks guys for the help i ordered the ord valve and filter dryer, To get them cooling temporarely. I backed out the (L shaped) oir valve 3 turns and the head pressure came down a bit and suction raised a little, it will cool for a day till parts come in. up here in northern wisconsin every thing gets ordered out no supply houses within 60 miles. I try to stock the most common things but on stuff like this that is new to me no such luck. The things I do stock is many kinds of freon, have seen to many guys that squirt whatever they have on had and f@#@ up what they work on so what the lable says is what i put in it well except r12 and r502 you know what I mean retro on that stuff when needed 404a and mp39 and such try to go by manufacture specs.
    getting kind of long winded here so I'll finish with the most important thought I have ! this is a great sight and I thank all who helped i will tell what the finish call turns out after parts go in.
    thanks Phil

    p.s. planned on changing the oil with system wide open when i found it im sure it sucked up lots of moisture.

    R12, apparently there's at least one thing about Hussmann you like.
