Connecting external dosing equipment (detergent, rinse aid)
18.3 Installing the dosing tube (rinse aid)
Fig.: Last main wash zone with dosing nipple for 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.
Route the dosing tube to the side cover taking a
short route and avoiding kinks. The hose must not
contact any hot surfaces or sharp edges.
Pass the dosing tube through the side cover to the
dosing equipment using a suitable cable gland.
18.4 Electrical connection
Connect the dosing equipment to the terminals as described in the corresponding equipment documents.
Terminal strip X7 for the electrical connection of the dosing equipment is located in the plinth of the rinse
zone. Refer to the machine circuit diagram for more information.

18.5 Commissioning the dosing equipment
