There really is no "upgrade" to convert the Prodigy to 220volts. The only thing that you need is the 220 volt subpanel which is a little expensive if the dealer charges retail. If you have a good electrician, get the wiring diagram ahead of time, and get your own breakers. With that said, the wiring and breakers is very specific, so don't stray from the diagram thinking it would work another way.
The only other thing required is changing the jumpers on the control pad when it gets powered up. There are basic instructions for doing this in the electrical info.
I am so damn confused now... my dealer told me I needed to upgrade the unit. Am I being taken for a ride here at my local HS dealer? The Prodigy is one of the hot tubs that me and the mrs really like (have yet to wet test). But we hate the idea of needing to "upgrade" anything electrical. Ugh this hot tub buying thing is so stressful.. I need a drink damn it.
The only thing that needs to be done to the tub is to change some jumper settings through the menu on the control pad. It takes about 30 seconds. As I said though the sub panel is pretty expensive and he may just be calling that the 'upgrade'. If you want the tub negotiate the price for the 110 version and get the 220 breakers on your own if you have a good electrician.
Agreed.
