Setting of the Dosing Quantity
The adjusting screw at the quantity setting valve must be turned until the upper edge of
the floater upper edge has reached the desired value in liters/hour at the scale of the flow
measuring pipe (see
For further Information: see Section 8. Initial Commissioning

The contactor shuts off the unit as soon as the floater sinks down (safety circuit).
When processing very small quantities ensure that the swimmer is actually capable to sink
down. Otherwise there is the possibility that the floater does not shut off even though the flow
rate has decreased to zero (risk of underdosage!!!).
Attention!
The device and the connected worm conveyor are automatically deactivated by the
contactor as soon as the floater, respectively the quantity sinks beneath the set value.
The prerequisite for this is naturally a precise setting.
