~0900 - 1100 hrs local -> Connected pump cart to BSC3 annulus
Kyle, Gerardo Used West Crane to "fly" pump cart into Beer Garden area -> Connected to BSC3 annulus -> Pumped annulus volume for a few minutes -> Noticed ion pump was "old style" rebuilt unit from 2002 -> pump has surpassed its lifetime and will be replaced at next opportunity as a matter of course.
