stretched areas in the tubing. Pay particular attention to the
pre-column area, as well as the area between the pump and
valves nos. 7 and 8 (see Figure 4-3.7), and between valves
nos. 4 and 5 (see Figure 4-3.5).

If any valve does not operate correctly, see troubleshooting
(chapter 5). This step can be repeated by using the “Undo” key
followed by the “Enter” key (see Figure 1.4).
The magnet drive will also be tested during this check sequence.
