Mount the storage vessel and the holder on the dosing unit as follows:
1 Rotate the centering tube on the distributor in such a way that the
marking rib on the centering tube is lined up with the marking rib on
the edge of the distributor.
2 Place the holder 6.2008.050 on the edge of the distributor.
3 Place the storage vessel 6.2008.030 for the buret tip in the holder.
In order to ensure perfect seating, the rib on the storage vessel must
be guided into the groove on the holder and pushed downward.
The holder can be placed at any one of four positions on the ring of
the distributor.
4 Slide the name plate 6.2244.020, which has the designation of the
reagent in the dosing unit, into the holder.
5 Slide the housing of the dosing unit onto the centering tube.
The centering tube with the cylinder unit must be in correct position
when the housing is attached. You will find a positioning aid on the
rear side of the dosing unit.
