    Assuming I've pleased the gods of vacuum, I'll be dropping 150 pounds of 422d in a carrier r22 chiller today.

    After intense research i randomly selected the higher viscosity POE oil. Rl64 i believe it was.

    I'll be watching obviously superheat subcooling, approaches, all the basic vitals. I guess most important is the oil sight glass and motor temps. If i had poor lubrication I'd overheat around the bearings i guess.

    Semi herm Carlyle recips, water cooled, roughly 100 tons. Never done this, I'll report how it works. Certainly open to any advise.

    Why 422 if you changed the oil?

    Because i was going to just give it a little POE to help with return, but the mineral i took out was gritty and nasty so i took it all. I wished i had Gone with 407C after that.

    Too damn confusing.................

    Add a little POE...........
    Add Supco 88..........

    Old semis where its easy to change the oil just change it and be done. Takes a lot of the ????? out of it.

    Personally haven't used 422D but like the R-12 days to each his own.

    Good Luck Pint. Keep us posted.

    Thanks guys. No that really isn't what i wanted to hear.

    Good news is I'm not running a low temp, I'm running 40 degree LWT so hopefully my results will be better.

    If you have a replaceable core suction filter on that chiller get replacements. If it doesn't have one install one!

    There's NO room for that. I was planning on it.

    The last thing you need is the suction strainers plugging up, hopefully they have them.

    We tried 407c on a Carrier 30GB080 air cooled and didn't have much success. Changed oil to POE. The EXV's where acting screwy and we could only get just over half the factory charge in before the head started climbing fastly. We pulled it and put R-22 back in it and she's been working great again.

    We put 407C, POE oil in a old Trane 100 ton water cooled with standard TXV's and that thing is running like a champ.

    I have a newly developed problem with this chiller, only 1 psi drop across the condenser barrel. First stage head high running on 22. They insist there's no booster pump for the tower water across the plant, about a half a city block away. Just what i need right now.
