Control Board Replacement
If necessary, the control board replacement can be performed while the manifold is in service. However, this should only
be done by qualified technicians experienced in servicing medical equipment.
1. Remove the two top screws at the base of the display board bracket and tilt back the display board assembly.
2. Disconnect the power supply.
3. Remove the screws located on the circuit board, detaching it from the front plate. Note the orientation of the old
circuit board and remove the wires one at a time and connect each wire to the appropriate terminal on the new
board.
4. Install the circuit board and fasten the screws to secure it. Turn the bracket to its original position and then fasten
the two screws at the base.
5. Reconnect power supply to the manifold cabinet.
6. Check the correct operation of the circuit board by simulating a bank switch over a couple of times.
