RichardL, sure thing, no problem. Thanks for the info.
I haven't been back to that job since. I'm going to talk with my service manager about it tomorrow. But Randy, when I started that chiller before the first time it happened, I had just shut down the other one, so the loop was still pretty cold. The noise cae about probably after 10 minutes of running, maybe more. After it went down on oil pressure, I couldn't restart it because of the anit-recycle timer of 20 minutes. By then, the water probably got up to low 60's or so. After I restarted , the noise came after about 3 minutes of running. It didn't purge becasue of the 60 minute purge bypass timer. Running the oil pump in maual yeilds a 39 psid, with no noise.
