In preparation for next week's vent, tested some LVEA vacuum equipment. Turned on LVEA purge air (Kobelco) unit and measured -39C dew point. Spun up three turbos (vertex, YBM, XBM) and QDP80s. Need long controls cable for vertex station. 

All systems OFF now, but left turbo power on until they spin down fully. Left water valved into Kobelco and QDP80s for cool down.
