Subject: leaking nitrogen line fixed 

I was lucky to notice that the nitrogen supply line to the vacuum valves was leaking. Closed ALL valves. Open supply line to atm. Fixed leak. 

This was done fast so the pumps did not have to be shut down. Pressurized supply line and open valves to

"Vac Normal" condition in the right sequence.
