Connecting external dosing equipment (detergent, rinse aid)
12.3 Installing the dosing tube (rinse aid)
Remove the cap (see arrow) and secure the
dosing tube with a cable tie.
Install a non-return valve in the dosing tube close
to the dosing point, because dosing takes place
against counterpressure.
Guide the dosing tube to the left side cover taking
a short route and avoiding kinks. The hose must not
contact any hot surfaces or sharp edges.
Guide the dosing tube to the dosing equipment.
Holes have already been drilled on the left and right
rear areas of the base plate.

12.4 Electrical connection
Connect the dosing equipment to the terminals as described in the corresponding equipment documents.
Terminal strip X3 for the electrical connection of the dosing equipment is located in the plinth on the front
right-hand leg. Refer to the machine circuit diagram for more information.
