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

[Matthew Marchlik]

Marc,

For the compressed air P&ID:

Please eliminate the "TO RICH #1 & #2 ATM" notes.

Add two dashed boxes to show boundary of RICH detectors and add the manifolds.

Add isolation valves where needed.

Move the pressure system boundary to encompass the manifolds.


For the N2 P&ID:
Add the isolation valve.

Matt

I have updated the p/ns on the diagram. The new parts are in red.
