Lift the Tube Bracket and Muffler Assembly away from the fan. Then pull the fan out of
the assembly (Figure 8). The fan is held in by mounts on the chassis, so it will require
some force.
Figure 8: Fan removal
Instructions for Replacing the Fan:
1. Insert the new fan in the allotted space on the chassis, making sure that the cable harness
is facing the motherboard and that flow of the fan is oriented downward (as shown in
Figure 8). The fan will snap back into the chassis mounts.
2. Route the harness under the Inlet tube and plug the cable back into the motherboard,
assuring proper connection by gently pulling on the cable (as shown in Figure 5.)
3. Clip the column tube back into the inlet union (as shown in Figure 7).
4. Slide the Tube Bracket and Muffler Assembly pegs back into the slots in the chassis.
Align the bracket back into place and reinstall the two screws to 4 in-lbs. (Figure 6).
Instructions for Reinstall the Housing:
1. To re-install the user interface panel, plug the LCD cable back into the motherboard
(Figure 4).
Note orientation of red wire.
Re-attach the cannula tubing to the cannula
connector (Figure 4).
2. Reconnect the UIP cable to the motherboard (Figure 3).
3. Test the function of each button and the LCD. If anything does not work, reseat the
cables in the connectors and check for debris in the connectors.
4. Re-install the four screws that connect the user interface panel to the chassis (Figures 1
and 2). Tighten screws to 5 in-lbs.
5. Place the device on its back side.
