Follow these steps to install the inspiratory manifold assembly:
NOTE:
•
The oxygen regulator assembly and oxygen module assembly must be
installed before reinstalling the inspiratory module assembly.
•
Always inspect o-rings between interconnecting parts and replace if
visibly damaged or rough to the touch. Always use new o-rings
supplied with replacement parts. Lightly lubricate o-rings with Krytox
GPL226 lubricant when installing, and relubricate at every
reinstallation.
•
When replacing original version of inspiratory manifold assembly, use
cable extension kit to rework main PCB to motor cable as described in
“Installing the Cable Extension Kit” on page 9-62.
1. Turn the two inspiratory manifold screws (Figure 9-70) a few threads
to secure the inspiratory manifold, but do not tighten yet.
2. Connect the silicone tube from the air flow sensor to the male port on
the inspiratory manifold. Route cables MTR O2, MTR BV and MTR EV
underneath the silicone tube.
3. Install the oxygen flow sensor (see “Oxygen Flow Sensor” on page 9-
57).
4. Tighten the two inspiratory manifold screws and torque to 5 in-lbs.
