5.2.1
Replacing the dosing unit
As a rule, the need for replacing the dosing unit occurs only rarely. The dosing unit has to be replaced, if such a
replacement becomes necessary as a result of a defect, or of an inspection of the titration unit.
The dosing unit is equipped with lateral ribs around its circumference, with one of these ribs being in double
design. This double rib serves as a mark for the correct placement of the dosing unit (Fig. 133).
