(see previous entries regarding over temperature issues with CS Kobelco and Vertex+XBM QDP80 pump) 

Investigation showed that the chilled water for the Corner Station was running low.  Supply to highest elevation was ~15 psi (30 psi normal). -> Added ~10 gallons of glycol to CS chilled water system and QDP80 temp warning ceased within 10 minutes.  Normal temperatures by 120 minutes -> OK
