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

Tue Dec 5 14:20:11 EST 2017

Hi Matt,

Can you give a status on the finalization of the Pressure Systems sign 
off? George is working on the individual components (manifold) for the 
upgraded parts. We will need to start the installation by sometime on 
Thursday. The upgrades must be done in time for the Aerogel installation 
next week. Let me know if there is anything else I can provide to 
expedite the process.

Thanks,

Marc
