I guess, I'm just used to filling the baths by sticking the hose through one of the chem. bottle holes. Seems quicker to me. I was concerned about ruining the selenoid by "not" having a cold water hose attached. I could hear the selenoid kicking on in an attempt to cool the 75 degree water that was in the bath today. I'll be sure to use ice to bring the water bath close to temp before turning the processor on, so as to not risk causing damage.
The temp dial on Cal's CPA has a pencil mark about an 1/8th of an inch below the 20 degree C line on it, indicating 68 degrees. Maybe his dial wasn't guite right. Because at that setting, the glasss thermometer has always shown 68.
Thanks to all for responding.
