IMPORTANT NOTE: Pay particular attention to J4 and J6 connectors and label if necessary to insure correct
installation when replacement board is in place.
Remove the cable from J16 (Figure 89). If the unit has the optional keypad.
Remove the four mounting screws and lock washers securing the flow computer panel (Figure 87: or Figure 88) to the
door mounted standoffs.
! CAUTION – Equipment Damage. When removing the flow computer board, grasp its outer edges. This
prevents damage to circuitry and components.
Replace and secure the flow computer panel on the four standoffs and secure in place using four screws and lock
washers. Do not over tighten the screws. Doing so could cause damage to the panel or associated circuitry.
Reinstall the connectors removed in Steps 5 through 11 in reverse order.
The circuit board is now reinstalled. If the replacement board does not include a new engine card, see section 6.9, Replacing the
CPU Engine Card. If restoring the configuration files, see section 6.2.3, Restoring configuration files (Restore), in page 109.
