Subject: Problem AG4100 SNF 2007-06-14 15:06:33: NH3 running low
Message-ID: <mailman.46.1356280410.3183.ag4100-pcs@snf.stanford.edu>

I'm trying to use NH3 for RTN, but NH3 flow rate drops off very quickly. I checked the back panel for gas pressure, and the NH3 gauge reads 0psi. So I guess NH3 is running low for this machine. Please note that I previously reported this problem for AG4108, but I meant AG4100. Please ignore the message for AG4108. Thanks.

User tried to flow 4 l/min, maximum flow should be 1 l/min.  If more is needed please see system engineer.
