Internal Assemblies — Introduction 4: Repair
95
To install the Rear Chassis Shelf:
1 Position the box display side down, shelf side toward you.
2 Position the Rear Chassis Shelf:
a Reconnect the two Internal Resistor spade connectors in any order to the Therapy PCA
positions J18 and J19, see Figure 56.
b If your device has the NBP Module, then:
• Pass the NBP air tube through the Rear Chassis cut-out above the SpO
2
plastic shield, see
Figure 55 on page 94.
• Reconnect the NBP module’s 10-wire bundle to the Processor PCA, see Figure 56.
c Align the tabs on the right side of the shelf with the slots in the Rear Chassis frame, see
Figure 54 on page 93.
3 Gently push the shelf handle into the Rear Chassis to align the screw holes
➊, ➋, ➌, and ➍.
4 If your device has the NBP Module, then reconnect the NBP air tube:
a Turn the device around, the Capacitor side toward you.
b Tilt the Rear Chassis, see “Tilting Rear Chassis” on page 91
c Remove the Battery PCA screw and move the Battery PCA out of the way for better access to
the NBP air tube. Do not disconnect any cables from the Battery PCA, see Figure 55.
d Reconnect the NBP air tube to the central airway nipple of the NBP Port, see Figure 55. Make
sure the tube slides all the way down the airway nipple.
TIP: You may wet the end of the air tube so it slides on the NBP Port easier.
NOTE: If you have the EtCO
2
option installed, then thread the air tube between the SpO
2
PCA and ECG
Connector. Depending on the available tools, you may have to remove the Measurement Module to do
this, see “Measurement Module with the CO2 Port” on page 128.
e Position the Battery PCA on the pegs and replace the screw, see Figure 55 and Figure 75 on
page 116.
f Ensure the connectors are fully seated.
5 If tilted, bring the Rear Chassis into the upright position, see “Tilting Rear Chassis” on page 91.
6 Install the M3x8 (T10) screws
➊, ➋, ➌ and ➍, and tighten to 6 inch-lb (0.7 N m), see Figure 54.
