4.4 The antistatic system (AS)
Friction in the suction hose causes electrostatic
charges which can result in unpleasant electric
shocks for the operator.
In order to conduct these static charges to earth,
the extraction units are provided with an antistatic
system as a standard feature.
However, antistatic hoses and accessories have
to be used in this case.
Caution: the antistatic function will only work if the
plug is plugged into a totally earthed socket.
