[Dsg-rich] corrected - Re: Upgrade to the RICH Valve panel

Thu Nov 30 12:09:17 EST 2017

Hi Matt,

Here are the latest upgrades to the P&I diagram. None of the filters 
have been installed yet. The N2 sketch includes plans to run up to four 
dewars through a manifold (four would only be needed during Christmas 
Break) . Please feel free to let me know of any changes needed. Thanks 
for expediting the matter.

Regards,

Marc
