If you hook up your vacuum gauge directly off the unit with all the other caps on, should it pull down to 50 microns or below rather quickly like I think it should?
Testing a unit I bought on Fleabay which the unit looks barely used but came with some mystery oil. I have run the unit through several purge cycles but still cannot get it below 5000 microns. All the seals are in the original Appion caps.
Fresh oil getting a little cloudy in short order which makes me think there are still contaminates in the unit.
