I'm thinking of upgrading my Aquapure from a 700 to 1400 to let me cut down on the run times needed to maintain the chlorine level in a small spa. This is one of the older versions with the display/controls on the front of the control box.
Reading through the parts list, it looks like all I need replace is the back PCB board, as that is the only part that has separate numbers for 700 and 1400. And obviously I will need a new cell.
Am I correct in my assessment.
