If necessary, press the spring tab on the NBP-to-Main Connector and disconnect the
NBP-to-Main Cable from the Main Board.
Note— If the Main Board has been removed from the Chassis, this cable may already
have been disconnected.
Remove the four 6mm T-10 screws holding the NPB Board to the Chassis and lift
the board from the Chassis.
Place the NBP Board on the Chassis with the pump facing up and on the outside
edge. The holes in the board should match the mounts on the chassis. Be sure the
two cables are under the board, and that one screw mount divides the ribbon cable.
Secure the board to the Chassis with four 6mm T-10 screws.
Make sure the NBP-to-Main Cable is attached to the connector on the NBP Board.
