So far the plan was to run the Pinnacle Spa Pack for my project on 120v because I thought that was all I had. Turns out the extra wire that runs to our garage ad then seems to go nowhere is actually a 220v line that someone ran and never connected to anything. With this new opportunity comes new questions. In the Spa pack there's a switch that goes between 120 and 240v. Is flipping this to 240 all I need to do to get this thing to run? Will my current pump, which will run (both high and low speed) on 110 also run on 120?
