Kyle, Gerardo Put viewport covers on (2) squeezer viewports (South door HAM4). Also, I was notified ~ 1hr into the rough pumping that the Vertex EH2600 roots pump was smelling "hot" -> I discovered that I had not opened the chilled water lines to this pump before running it -> I cracked open both lines and noted that the return line was hotter than normal. I made a few iterations of slightly increasing the cooling water flow, followed by waiting several minutes, then slightly increasing flow, waiting etc... After ~30 minutes of this exercise the pump temps returned to normal.
