Note to the customer
Warewashing machines, bedpan washers and systems are provided for the permanent
connection to the electrical power supply and the connection to the on-site potential
equalisation system and are accordingly equipped with a connection option.
The operator can decide at his/her own discretion and under his/her own responsibility to
alternatively implement personal protection in collaboration with a licensed electrician
company using:
 Fault current protection switch sensitive to universal current with max. 30mA EN
62423
or
 Automatic switching off of the supply when the protective earth conductor for the
consistency is lost (EN 60204-1 Chap. 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.

The fresh water connection must be effected as per EN 1717 or local regulations.
The minimum flow pressure of the clean water supply upstream of the solenoid
valve must be 2.5 bar.
The minimum flow pressure of the clean water supply upstream of the solenoid
valve must be 2.5 bar with the booster pump option.
The maximum pressure must not exceed 5 bar.
 If the minimum flow pressure is not reached, increase the flow pressure with a
booster pump; if the maximum pressure is exceeded, limit it with a pressure re-
ducer.
 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. Corre-
sponding instructions are contained in the installation drawing. Appropriate
measures must be taken.
 A dirt trap must be fitted into the fresh water supply to protect the solenoid valve.
