I have an Aqua Rite system with a turbo cell.  How do I determine what kind I have.. I can find any model numbers.  The main Aqua Rite has a number of 5A0605-1038450,and the turbo cell has a number on it that appears to be 6E0605-2047265

The system has given me the PCB with all four LED lights solid indicating I need a new board.  I would like to put it in myself but don't know which to order.
