    York Max E YR Chiller

    When I did the pre season work on this chiller I found that the oil filter canister was filled with mostly mostly R134A refrigerant. Is their any way to keep this from happening?

    Manually run the oil pump to get the hot 134less oil into the filter canister, or wrap a small heater blanket around the filter housing for a little while.

    It should be differential pressure no pump.

    After a while you realize that while you are getting
    dirty, the pig is actually enjoying it.

    It is not exactly cheating, I prefer to consider it
    creative problem solving.

    Centrifugal on the brain. The blanket would still help.

    Warm it up with a heat gun.

    Or valve it out and recover to one of the other ports. Seperator is real close!

    Is the refrigerant in the oil canister a problem? It will disappear when you run the compressor. So do that before you are going to replace the filter cartridge. Don´t worry about compressor lubrication, the roller bearings don´t mind it if it does not take too long until oil flow establishes. But there is probably a problem with your discharge superheat if you get pure 134a in your oil canister!
