nected with the drinking water mains, when an appro-
priate backflow preventer has been installed, Type BA
according to EN 60335-2-79.
• The backflow preventer can be ordered under number
106411177.
• As soon as drinking water has flown through the back-
flow preventer, it is no longer regarded as drinking
water.
• Operation by suction (e.g. a rainwater vessel) is car-
ried out without a backflow preventer – see “Connec-
ting to a pressureless water supply”. The machine
can be connected to water mains with a max. inlet-
pressure of 1 MPa/10 bars and max. 40°C.
Safety devices
Locking device on spray handle:
• The spray handle features a locking device. When the
pawl is activated, the spray handle cannot be ope-
rated.
Thermal sensor:
• A thermal sensor protects the motor against overload-
ing. The machine will restart after a few minutes when
the thermal sensor has cooled.
