Ask 'Dr. Spa' Q & A Message Board

I have a Waters Edge Spa which I obtained recently as an "AS IS" unit needing repair. It is not set up yet but I am trying to get things ready for when I can get it set in position. It or the control panel have a model number WE24033H on them. The control is of the older type with the timer and pneumatic switches. The control panel is shot as far as the sheet metal goes but that is not a problem. I am an electrical engineer and intend to rebuild the control using a new enclosure. The timer looks OK. The pressure switch is the same. The high limit thermostat will need to be replaced as well as most of the pneumatic switches. I have an APC catologue which seems to have all of these items in it. I am considering using a heater that came out of a different unit that has its own small circulator pump attached to it. I would like to find the schematics of the control especially the heater section which seems to include a topside digital display. I have seen newer electronic controls which realy don't offer anything spectacular that this type of unit can't do just as well. The topside control appears to be in good shape. I also need a complete water and air plumbing schematic. This unit has water jackets on the two main pumps.
