I'm not a chiller gorilla by any means but i thought due to the filter, nothing would make it past to the bearings. I always changed the oil filter before 500 hours and did a base line oil analysis from the factory and did what it said and they always reported in big letters do not change oil at this time. I also thought that it was a "green" item to not change oil?
On seven E's on one property all started up at the same time and all evacuated correctly one always had plating, I mean bad, bad enough it would coat the oil filter. Never one leak never any issues at all with the machine. Vibration tests always in line and lasted till the 10 year overhaul when it (thrust) was replaced as a maintenance item during tear down.
I always change the filters every annual though and did oil analysis on all machines. Never one issue with moisture or anything out of the ordinary.
Always learn something here though. I thought they didn't know what caused copper plating exactly. The late 90's machines I believe they started dropping oil heater operation out after start up to help reduce copper plating and power consumption to a smaller degree.. but like I said I learn something new everyday.
Two wire hook up, three wire f**k up.
On most Tranes (recient production) it was from the tubes. The provider of the tubes was leaving cutting oil and cpooer dust on the tubes. changing the filter would not protect the machine. Oil testing works but usually with copper plating its best to keep an eye on the oil and simply dump it at 500 hrs.
