Checked that the cooling water was running this morning.  Won't run with these faults.

Installed new recirculator.  Need to be tested.

Resetting temperature switches ...
There is a new heat exchanger but, as of yet, we have not yet determined how effective this new cooling strategy is.

Found one of the chamber water cooling lines had popped off.  Repaired the water line.  Also lowered the line pressure from 60 to 50 psi.  Noticed the water was very dirty.  Ray S. flushed out the chiller.
Turned chiller back on.  We will leave the system on shutdown over the weekend and continue to monitor for leaks.   Also need to check how the system will perform with the lower water pressure.
