4.2.3 Water Filling Station
The machine refills itself at the water filling station (7) (see figure 8 on page 4-1). The water filling station
has:
• Mechanically operated shut-off valve
• Water outlet
When the water filling station is connected to the drinking water system, a header tank must be installed
between the drinking water system and the water filling station to prevent the pollution of potable water
by backflow of water with bacterial contamination (see Hygiene protection in Specifications (see page 3-
1)).
The header tank supplies water with a constant pressure (0.2 bar) to the water filling station. The water
station is installed next to the charging station on the wall. The header tank is installed 2 m above the
floor
