4. Remove the air flow sensor (see “Air Flow Sensor” on page 9-65).
5. Remove the vent port tubing from the inspiratory manifold.
6. Disconnect the tubes from the inspiratory, exhalation, and safety valve
solenoids.
7. Remove the green ground wire from the manifold.
8. Loosen the recessed 2.5-mm hex set screw on the outlet port, but do
