    Mcquay PEH087 Oil and IGV Problem

    Hi all, I have this chiller PEH087 it gives me a closed vane alarm and low oil delta P pressure. I read the feed pump pressure it was 950 KPa first run; then it declined to 720 KPa the net Pressure was 323 KPa. I ask if I have a problem of oil leak in the inlet vane guide or the problem in the Pump itself.
    Thanks for your suggestions.

    O-rings are most likely trashed.
    Open and see.
    Good luck
