In the following chapter, figures are given in brackets to clarify what needs to be
done. These numbers refer to image and list above.
3.5.1 Electrical connection
Information about electrical connections (1) is available on the machine’s wiring
diagram which is provided on delivery. Store these in the special plastic document
wallet.
• The machine is designed for quick electrical installation.
• The machine has a built-in main switch (16).
• Connect the electric cable at (1). In special cases, certain dishwashers may
have an electrical connection from the floor. The cable is then drawn be-
hind the cover plate at (9). Protect the incoming cable with, e.g. Pipe for
connection cable, WD212.4102 (option).
• Check the direction of rotation of the pump motors during operation when
the tanks are full of water. The direction of rotation must conform without
exception to the direction of the arrow on the pump. Stop the dishwasher
immediately if the direction of rotation is incorrect and change two of the
incoming phases.
After completing the installation, switch on the main switch and all circuit break-
ers.
3.5.2 Water connection, regardless of any options
• A shut-off cock must be installed on the incoming pipe.
• It is important that the water supply has sufficient pressure to ensure the
correct flow of water to the machine. The required water flow and pressure
can be found in the TECHNICAL SPECIFICATIONS. If the water pressure
is too low, a booster pump must be fitted.
The water pipe is connected at (2, 3) or at (10, 11). If the machine is connected
with a hose, this should be steel braided and have an internal diameter of at least
12mm.
The hot water connection (3) on the machine is fitted with a filter.
The cold water connection (2) on the machine is fitted with a filter, non-return
valve and vacuum valve.
As the machine is fitted with a break tank, the connection is fitted with a filter and
non-return valve.
