Symbols on the machine
High-pressure jets can be dan-
gerous if improperly used. The jet
may not be directed at persons,
animals, live electrical equipment or at the
appliance itself.
According to applicable regula-

ternatively a system separator according to
EN 12729 type BA must be used.
Water that was flowing through a system
separator is considered non-drinkable.
