Proceed as follows:
1 Guide the upper part of the septum stopper over the tip of the
6.1830.030 heating tube as shown in the illustration.
2 Guide the E.3010.032 O-ring over the heating tube.
This O-ring is also part of the 6.1244.040 set of seals that is enclosed
with each KF titrator. It cannot be reordered individually.
3 Guide the lower part of the septum stopper over the heating tube
and screw the three parts together (not too tightly).
4 Insert the stopper with the tip of the heating tube into the front
opening of the KF titration cell
5 Shift the height of the tip of the heating tube vertically in such a way
that the outlet opening of the tubing is immersed as deeply as possi-
ble. The tip must not however be permitted to get in the way of the
stirring bar in the KF titration cell. Afterwards give the septum stop-
per its final tightening.
