DANGER
Risk of fatal injuries on account of electric
voltage! Required electrical work must only
be performed by an electrical specialist.
– The socket must be secured through a
residual current device (RCD) with a
triggering current of 30 mA.
– This socket must be located close to the
work station so that the plug can be
pulled immediately in case of an emer-
gency.
– The interior cleaner is standard
equipped with spray nozzles that are
designed for a flow rate of 900-1200 l/h
(15-20 l/min) (nozzle set no. 2).
– If the high-pressure pump has a differ-
ent flow rate, the nozzles must be re-
placed as per the table.
– The minimum pressure value of the reg-
ulating valve must be set prior to switch-
ing on the high-pressure pump. This
way, the interior cleaner will not be ex-
posed to pressure peaks when switch-
ing on.
