Ron, I have the 1/3. This is the first chiller I have had that I needed to make so many darn adjustments. It's has some nice features, but I had to adjust several things to get it working correctly. Here are a couple of things I needed to do to get it pulling down my temps otherwise it'll constantly be one and doesn't bring down temps.
- Air circulation in the garage.
- Room temp. (pm me or give me a call if you want to know what I did to the garage)
- flow through. They recommended 30/800gph. When I put a 600-700 gph pump on it didn't pull worth anything. I had to bump it to about 1100 to get it to drop.
- changed the 5/8" tubing to 3/4"
I can now get about an 8-10 degree drop.
BTW still on for the 9th?
