Attention! If you switch the unit on the first splash always starts with a
delay of 30 minutes (set up ex works). This switch-on delay can be
switched-off manually (see wiring diagramme).
The fragrance dosing is only unlocked if water flows through the unit.

The dosing pump
For the fragrance dosing a peristaltic pump that
conveys smallest dosing quantities is used, even when
there are gas- or air bubbles in the suction tube.
Revolving rolls push the dosing hose against a walling
whereby the the liquid in the hose is pressed out in
front of the rolls and sucked back behind them.
It is extraordinary safe in its
function an in addition to this very
easy to handle (see mounting).
Fragrance concentrates are extremely aggressive. The used
dosing hose is resistant against the most concentrates that are
common in trade. Lifetimes from some months to some years are
possible. But there are also concentrates against which the hose
in not resistant. So we are not able to provide a warranty in this
case!
