[Kyle, Chandra]

In preparation for anticipated vertex vent, we tested vacuum equipment:  QDP80 roughing pump, Kobelco purge air skid, and vertex turbo & scroll pumps. All ran satisfactorily. Purge air measured -43.7degC dew point. A few notes:

• need access to LVEA later today or tomorrow to de-energize vertex turbo station after turbo is fully spun down
• left cooling water valved in to QDP80s and the Kobelco energized for further cooling after being powered down
• swapped battery pack on vertex turbo station with one that was fully charged
• purged the QDP80/turbo header with clean air before turning pump off (header/purge air isolation valve back in closed position)
• noted a leaky flange on purge air line under XBM
• found that the Kobelco oil temp. was hot - needed to crack open the cooling valve in back *slightly* more (~1/8 turn)
• recommend better labeling of control cables to QDP80 pumps
• need to make a long control cable for vertex turbo station (we used jumper and powered up QDP80 from XBM turbo station)
• installed a filter on vertex scroll exhaust
• had fun
