I was recently given a Sunset model 1525, it is a 3 (4 if you are real friendly) person hot tub. It has a Hercules Tornado (m/n HFM06MD11-001) series controller. I do not have a manual for this tub. It is currently wired for 110, but is capable of being run on 220. I would like to run it on 220. Does anyone know where I can get a copy of the manual or electrical schematic that will show me which wiring changes are required internal to the controller cabinet? It appears to just have one jumper going from the heater contactor/switch to the pump contactor/switch that will need to be removed, but I would feel more confident if I had a manual. And does anyone know who manufactured this tub, was it possibly built by Leisure Bay?
