Which part? Nothing electrical is near the open water. The wire that's in there is the thermostat tube, and the wiring behind will be cleaned up before it gets put to use. It was only hooked up to test. Not being a smart ass, just curious. If there's a safety issue I definitely want to address is.
I figure I'll need to get the water somewhere close to 35º, or use glycol to get between 25-30º in order to get my solution in the low to mid 60's. When I was running through a coil in the fridge and the temp inside was around 38º, my solution would be 66-68º. If I was away for a couple days, and couldn't change out the ice bottles, the fridge would get close to 50º, and my rez temp would be 75-77º.
