EDP200 s/n CSM1166
Oil level good but dirty -> Internal coolant ~12 fluid oz. low - Added ~12 fluid oz. of 50/50 mix of distilled water and Drystar coolant w/rust inhibitor.  Installed modified ASA blank to cap inlet.  Modification included tapped hole allowing addition of a mechanical vacuum gauge and 1/4" ball valve for gas admission.  Ran pump for 1 hour with the only load being 2 LPM of UHP GN2.  Pump ran quiet and achieved operating temperature; pressure < 29" Hg - no problems with this unit - Same as last week for s/n CSM1165
