Note to customers
Dishwashing machines, bedpan rinsing units and systems are intended for fixed, electrical power
supply installation as well as connection to the locally available equipotential bonding and have
been equipped with a corresponding connection option.
Operators may decide at their own discretion and responsibility to implement personal protection in
locally available services in collaboration with a specialist electrician registered at the correspond-
ing energy supplier using the following:
• AC/DC sensitive fault current protection switch with at max. 30mA EN 62423
or
• Automatic shutdown of the supply in the event of loss of protective earth conductor conduc-
tivity (EN 60204-1, Section 8.2.8.c)

Requirements for the fresh water connection

Each appliance carries the DVGW test symbol and does not require an extra safety
valve in the water feed.
• Fresh water connection must be made according to EN 1717 or according to local
regulations.
The machine is equipped with a water supply air gap (group A, model A in ac-
cordance with DIN EN 1717).
The requirements of the clean water supply in the accompanying GiO module op-
•
erating and service manual are to be observed for machines equipped with the GiO
module.
Observe the following limits for the fresh water supply to machines with the AirCon-
•
cept exhaust air heat recovery system:
- Water supply temperature max. 20°C
- electr. conductivity > 100 µS/cm
In case of electr. conductivity < 100 µS/cm (e.g. in operations with complete de-
mineralisation or reverse osmosis systems) the stainless steel heat exchanger
available as an option must be used.
The minimum flow pressure of the clean water supply upstream of the solenoid
valve must be 0.6 bar; if water-softening (AktiveClean) equipment is incorporated
into the machine, it should be 1 bar; and for machines equipped with the GiO mod-
ule it should be 1 bar.
The maximum pressure must not exceed 5 bar.
If the flow pressure is below the minimum, increase the flow pressure with a booster
•
pump; if the maximum pressure is exceeded, limit it with a pressure reducer.
A water stop is integrated into the fresh water inlet of the machine. This, together
•
with the leak water switch in the floor pan of the base, ensures that the fresh water
supply will be cut off in the event of any leak
Suitable protective measures must be taken to ensure that no iron particles can
•
enter the appliance via the mains water supply. Similarly, precautions must be
taken to prevent the entry of other metal particles, for example copper turnings.
Corresponding instructions are contained in the installation drawing. Therefore
suitable measures must be taken.
• A dirt trap must be fitted into the fresh water supply to protect the solenoid valve.
For Australia only:
All work carried out must be in accordance with AS 3500!

Requirements for the waste water connection

A waste water pump is integrated in the waste water line (further information about
•
this is in the technical sheet).
The drain hose must be connected to the waste water pipe in the building.
•
A grease trap may be needed, depending on the machine application.
•
The requirements of the waste water supply in the accompanying GiO module op-
•
erating and service manual are to be observed for machines equipped with the GiO
module.
