York Chiller

[tomt]

York Chiller YTH series, with YDTH compressor, R-123.
Unit was shut down in 1997, Cooler sight glass showing half glass r-123. I pulled oil filter, looks like it came out of a car that ran the Nascar circuit.
I know the oil cooler under the evap must be holding 3 gals. I added new oil in reservoir then turned heater on, put pump on manual flused out through filter access port.
Taking some time to do this plus cost of the oil.
Anyone have any other alternatives.
Thanks
