For the water connection, the backflow prevention devices (dual
check valves) must be used.
The backflow prevention device to prevent backsiphoning must be
installed between the tap and the water inlet hose during
commissioning on all machines. The non-return valve prevents water
from the water inlet hose from flowing back into the on-site drinking
water supply.

at an angle. Unscrew and reconnect the water correctly before
