Update November 16th, 2006 Riccardo Sartor – DWS Customer Support
All our dishwashing machines are prearranged for the installation and the control of external chemical dispensers
(detergent and rinse aid).
The “hydraulic” connection of these devices is possible just removing bolts sealing prearranged holes in the tank.
This is to avoid drilling on the tank
Hydraulic prearrangements
The “electric” connection of these devices must be done using the specific well-identified terminals in the wiring harness of
the machine.
These terminals are reached either by removing the screws of the electrical connection box or the frontal panel; behind them
you will find the terminal block to wire external devices.
Prearrangements make easy and safe the connection of external dispensers, without jeopardising the electrical and
operational conditions guaranteed by Electrolux (CE marking).
