Hydro-Quip PCB PS6603B # 33-0033B

Balboa circuit boards are marked with a “Chip Number” that is located on a white label placed on the logic chip near the center of the board. It is imperative that this number is supplied to Swim CSI for proper circuit board match. Just because boards may look similar the programming may not allow it to work properly in all applications. Please review our Balboa Chip Cross Reference below.
