6.1.3 Requirements for the waste water connection
6.1.4 Requirements for the fresh water connection
Pressure range of the fresh water supply flow pressure upstream of the solenoid valve:
Maximum pressure
Measures to ensure correct water pressure:
Other measures:

A waste water pipe is integrated into the drain pump.
•
Connect the drain hose to the on-site waste water pipe.
– For Australia only:
The drain hose must be connected so that it is waterproof with a drain fitting
in accordance with AS 1589 AS 2887 and a sanitary waste water pipe or
sanitary waste water fitting in accordance with AS / NZS 1260.
•
Depending on the dishwashing machine application, a grease trap may be in-
cluded, based on the general/location-specific regulations.
•
Observe maximum drain heights above the finished floor.
Note
Where the water conductivity is σ < 100 µS/cm, the stainless steel variant of Air-
Concept must be used. This is the case when using a reverse osmosis (GiO) or de-
mineralisation system, for example.
For Australia only:
All work carried out must be in accordance with AS/NZS 3500.1!
Fresh water connections and their components must be carried out in accord-
ance with local regulations, e.g. EN 1717/DIN 1988-100. The fresh water must
be of the same quality as drinking water in microbiological terms. This also
applies to processed water.
The basic model of the dishwashing machine features an air gap (type AA or AB as
per EN 1717 or EN 61770). In the case of SVGW (Switzerland) and other countries,
a type EA safety device (at least) is also required in front of the connection hose,
depending on the machine version. Installation components and materials must be
suitable and permitted in accordance with local regulations. A solenoid valve is inte-
grated into the dishwashing machine's fresh water line. This, together with the leak-
age detector in the base drip tray in the subframe, ensures that in the event of a leak
within the machine, the fresh water inlet is shut off.
•
Machines with air gap or pressure booster pump:
60 – 500 kPa (0.6 – 5 bar)
•
Machines with a safety device to prevent backflow:
250 – 500 kPa (2.5 – 5 bar)
•
Do not exceed maximum pressure of 500 kPa (5 bar).
•
If the minimum flow pressure is too low, increase the pressure using a pressure
booster pump.
•
If the maximum pressure is exceeded, limit the pressure using a pressure regu-
lator.
•
Ensure that no foreign iron particles can enter the appliance via the fresh water
connection. The same also applies for contamination by other metal particles
(e.g. copper shavings). Corresponding instructions are contained in the assem-
bly plan.
•
A dirt trap must be fitted in the fresh water supply to protect the solenoid valve.
•
After the dishwashing machine has been unused for an extended period of
time, drain the connection line and wash it before putting the machine back into
operation.
•
When replacing an old machine with a new one, make sure that the existing
feed hose is exchanged for the new feed hose supplied with the machine.
