7. Route the gas tubing:
• If the detector is installed in the back position, route the tubing
behind the manifold, over the top of the chassis, and through the
slots as shown in Figure 350-17.
• If the detector is installed in the front position, route the tubing
behind the manifold and over the top of the chassis. Run it directly
to the detector; do not run it through the slots.
8. Connect the ribbon cable to the mating connector on the pneumatics
board. Arrange the cable to keep it away from the valves and keep it from
being pinched against the manifold.
For the back detector, you may want to loosen the manifold and slide it
out of the carrier a few centimeters to connect the cable to the pneumatics
board. Then reinstall the manifold.
9. Secure the manifold in place using the Torx T-20 mounting screw.
