I was working on a refrigerated display case made by AKE of Europe. The system had a restriction in the liquid line just after the filter drier. In the process of troubleshooting and repair I was putting dry nitrogen through the lines to insure the restriction was clear when a slug of oil shot out and made quite a mess. Oil poured out of the tubing and it was not possible to measure the amount however I would venture to guess it was maybe 1 to 3 ounces. The Danfoss specs state it requires 18.5 ounces of POE. There are no service valves, only a schrader on the process tube.
Questions; 1) How much oil loss would cause a critical effect? 2) If I knew how much oil was lost and wanted to top it off how would I go about it with only a schrader on the process tube?
Thanks Ken..
