dosing pump is normally (standard supply) sourced on from the plant Main Control Box and
the operator has only to connect the plug that comes from the dosing pump to the correct terminals of the ECOmar S main
control box (refer to attached Electrical Connections Diagrams).
This is valid only for the ECOmar S plant supplied with the standard (
1 Tank Control
) configuration. While, when the plant is
supplied with the
2 Tanks Control
configuration, on the rear side of the H

O
2
Dosing System (see figure below) there is an
electrical box, to be connected to the Main Control Box. Moreover, when the plant is supplied with the 2
Tanks Control
configuration for the 3 phases power supply, an auxiliary power supply 230 V AC (your supply) has also to be brought into
the electrical box of the H2O2 Dosing System (refer to attached Electrical Connections diagrams).
