    can't give any DIY in general forum. If you are a tech, get post count to 15 and apply for pro membership. Then move questions to pro forum and we can help you there.

    If you don't know, then don't do. If you don't know and still do, then be prepared to pay someone else a lot to undo what you did and then do it right.

    If you do know, then do. But do it right. Otherwise, you may not be doing it long.

    As above, this becomes a technical question. we're not allowed to give technical, or DIY in the resi forum.
    We would like to ansswer your question. But teh site rules forbid us.

    But look at your guages again, R22 at 60PSI is not 30* SST.

    How many times must one fix something before it is fixed?
