13.2 Replacing the discharge tube

13.2.2 Filling valve

1. Pull out the recirculation tube and the telescoping filling tube
(Fig. 1).
2. Use the mounting tool to unscrew the filling valve (Fig. 2).
3. Screw in the new filling valve first by hand and then tighten it with
the mounting tool.
Note:
If the instrument does not fill up, and if some elastic resistance is
evident when the piston is pulled upward, then it is possible that
the ball valve is stuck.
In this case, loosen the ball valve using light pressure, for example,
with a 200 µl plastic pipette tip (see the figure at the side).
