Discovered a leak in the discharge line. Was in a difficult spot so I cut it out and built a new section of tubing with a filter drier. Brazed it in and checked for further leaks and found none. Swept the system with nitrogen and pulled a deep vacuum down to 400 microns that held for ten minutes. Had to change vacuum pump oil 2 times and use a whole bottle of nitrogen to remove all moisture from the system. Charged the system or manufacturers recommendations, ran and tested system. Compressor is pulling slightly high amps at 8/13.5 with a good capacitor. Otherwise unit is running fine.
