13. View each surface of the center section under reflective light to
confirm that it is clean, dry, free of lint and fingerprints.
14. Place the center section aside on a clean nonabrasive wipe. Use
care to avoid scratching the surfaces.
15. Align the lock notch of the rear section with the mounting guide.
Carefully slide the section back as far as it will go. Avoid crimping
any of the attached tubing.
16. Place three drops of shear valve lubricant on both clean, dry
surfaces of the center section.
17. Spread a thin, uniform layer of lubricant over each surface with a
clean, dry, gloved finger.
18. Align the center section so that the rim notch in the outer edge
faces to the right. (Refer to

section is installed backwards. Be certain the rim notch faces to
the right.

Aspiration Peristaltic Pump Tubing
The tubing in the aspiration peristaltic pump needs to be replaced on a
regular basis to ensure proper fluid movement through the instrument. The
frequency of replacement depends on instrument use in each laboratory.
Abbott recommends changing the aspiration pump tubing weekly. A
peristaltic pump is depicted in Figure 9.7 .
