Requirements for the fresh water connection
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 is also required in front of the connecting hose, depending
on the machine version. Installation components and materials must be suitable and
permitted in accordance with local regulations. A solenoid valve is integrated into the
dishwashing machine's fresh water line. This, together with the leakage detector in
the floor tray in the frame, ensures that the fresh water inlet within the machine is
shut off in the event of a leak.
Pressure range of the fresh water supply flow pressure upstream of the sole-
noid valve:
• Machines with no GiO MODULE:
0.6
– 5 bar (60–500 kPa)
• Machines with GiO MODULE or ActiveClean water softener:
1
– 5 bar (100 – 500 kPa)
Maximum pressure
• The maximum pressure of 5 bar (500 kPa) must not be exceeded.
Measures to ensure correct water pressure:
• 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.
Other measures:
• Ensure that no rogue iron particles can enter the appliance via the mains fresh
water connection. The same also applies for contamination by other metal parti-
cles (e.g. copper shavings). Corresponding instructions are contained in the
installation drawing.
• 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 rinse 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.
6.1.5
Requirements to the electrical connection
Warning
Danger to life from electric shock
Contact with live electrical parts can lead to serious injury or death.
• Work at or repairs to the electrical system must be conducted by a qualified
electrician who complies with the electrotechnical rules.
• Disconnect the machine from the power supply before working on the electrical
system. To do this, turn the local mains switch to
OFF
and ensure that it can't
be switched back on again.
Note
The wiring diagram is located behind the front panel of the dishwashing machine.
This must remain in the machine!
The type plate with the electrical connected values is located inside the front panel.
