Removal
1. Open the lower chassis as directed in Heading 4.4.
2. Gain access to the aperture area by removing the Diluter Panel shield with door. The
shield is held in place with three captive thumbscrews.

attached to the RBC aperture sweep-flow fitting on the Diluter Panel (Figure 4.26-1).
ATTENTION: Do not remove the upper left and lower right screws. This will release the box
shield attached to the back of the Diluter Panel.
4. Remove the face plate covering the sweep-flow tubing spool that is held in place by two
Phillips-head screws, one lower left and one upper right (Figure 4.26-1).
