Only screw up was that Unitec built the new power unit using the sales number and everything was correct except for the valve solenoids came 120vac and were supposed to be 120vdc. My bad as I assumed (we all know what happens when you assume) that Unitec/Otis using their own original build info would get the coils right and I never checked it on the quote. I checked everything else but that. Luckily I had four of them.
