Dosing Assembly
The dosing assembly, placed into the main housing consists of the dosing hopper (5a) and the dosing
unit with dosing motor (6a) pushed into and screwed to the motor holder (6b) the dosing
screw (6c) and the dosing nozzle which is heated eliminating condensation of the warm pool water
vapour. The dosing unit is screwed into the dosing hopper. The required dosing rate is adjusted at the
control board by means of a dosing cycle and dosing time – see para 1.5.

knocker
The knocker (6e) gives a stroke to the dosing hopper wall
and thus prevents clogging of the chemical.
The complete dosing assembly can be taken out of the
frame for service.
With the shown fitting systems chemical containers of 10 kg can be fitted directly to the hopper so that
the chemical must not be moved from the container to the hopper.
