5 INSTALLATION OF THE pH REGULATION PART

5.1 Location

STERILOR Duo

The electronic box must be installed in the

technical room protected from sunlight, bad

weather and close to the electrolysis cell (2.5

m cable).

The controls of the box (switch, electrode

connection and fuse holder) must remain

accessible.

For correct priming of the injection pump, the

height between the product suction strainer

and the pump of the box must not exceed

1.50 metres.
