Listen to Mr. Kollmann.
I bought the CU200 ten years ago and installed it myself - without the water cooling system hooked up, air only. I figured that if it couldn't keep up with the load I would add the water cooling parts
. Easy for me because my previous system was water cooled so I already had a thruhull available.
Ten years on and I haven't hooked up the water cooling system yet. It simply doesn't need it. Just give the aircooling system plenty of air circulation. In fact, I used the water cooling connection on the control module to run a computer fan when the system is on. It forces air over the control module and compressor and to the condensor. If you get a chance to read Richard Kollman posts he will tell you that the critical part on the AB is the control module; keep it cool by blowing air over it.
And guess where we cruise
and the Bahamas - in the summer!
If I had it to do over again, I would have bought the CU100, and, with the money
I saved, would have bought the larger evaporator. I bought the smaller evaporator and although it works well the larger one would have given us a bit more freezer
