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 125.).
