Due to back issues my physical therapist recommend i get hot tub. Budget issues prevented me from getting new tub , I found a tub in classifads that had One 120v 1hp pump motor,5.5kw heater ,spa light 7 small jets on lounge , 1 small jet down by drain and 6 rotating eyeball type jets that look to be in a 2 1/2 inch hole . a 120v feed .( Im a electrician with control exsp) I was very disappointed on performance! So i started looking into ways to improve it. First thing i found was that it could be chaged to run on 240v . So i ran new 240v 50amp gfci line and changed setting in panel and now it maintains 104deg but im still not happy with the power of jets. The motor is still running on 120v and is 1hp (2 speed),not sure of gpm. My first idea was to change motor to 240v 1.5 or 2hp . I know the circut board and wiring is set up to do 120v or 240v motor . Secondly i thought changeing the jets from a single eyeball type to a mutiable port massage type jet would also help. Im having a hard time finding jets that will replace eyeball without chaging complete jet assemply. So ive been hunting parts from old tubs Money being a issue Ive been looking in classifads and I have had some luck in locating parts from people upgradeing there tubs and looking for help getting rid of old equipment. So now i have 1 topside control panels ( 1 ,8 button with 8wire conection 2 motors , single speed 230v 3450rpm 5.7 amps which I estamate to be about 1.5hp 1 120v blower motor with fittings and tubing but no jets Assorted shut off valves and pvc and tubing 1 main control panel that was used to control 2 motors ,spa light ,heater,ozone genrator, inputs for temp,hi limit freeze,pressure switch , 20amp or 50amp options , 5 hr or 2 hr filter option,and its missing the original top side control buttons however i do know it had a 6 wire control panel. Then theres the orig control panel that is running the tub now. All i have to guide me is pictures of the newly required parts installed on old tubs before i removed them. wireing diagrams that are on control panel covers. Where can i find some tech manuals ,wires schamatic for control boards , Also would like to find some plumbing diagrams to see the best way to seperate my exsisting plumbing to have the tub use 2 motors and blower. I know this might sound crazy to some but im in need of a more powerful tub and also in need of a project , Ive built complcated electrical control system in the past and i have over 25yrs exsp in the electrical industry. Any advice and links to tech support schamatics would be greatly appreciated
