I inherited an older Jacuzzi (Echo? made sometime between 1995 and 2000) spa and want to install and convert tub to run on 230volt. The wiring diagram is not readible on the control box.

Clearly, the documentation supports this conversion, but I have not been able to find any online wiring diagrams

Does anyone have a wiring diagram for the Balbo Instruments Model H136000 DU-H136-CCAH with circuit board P/N 51424. Or a conversion description on the wiring modifications.

regards and thanks
