Extensions

If an extension is used, make sure it is fit for the power draw
and protection degree of the vacuum cleaner.
ATEX variants: extensions, plugged in electrical
devices and adapters cannot be used when the
vacuum cleaner is used for flammable dusts.
Minimum section of extension cables:
Maximum length = 20 m
Cable = HO7 RN - F.
Max power (kW)
Minimum section (mm )

Sockets, plugs, connectors and installation of the
extension cable must maintain the IP protection
degree of the vacuum cleaner, as indicated on the
data plate.
The vacuum cleaner's power socket must be
protected by a differential circuit-breaker with surge
current limitation, that shuts off the power supply
when the current dispersed towards ground exceeds
30 mA for 30 ms or an equivalent protection circuit.
Never spray water on the vacuum cleaner: such action
constitutes a danger hazard for persons and could
short circuit the power supply.
Consult the latest edition of the European Union Directives,
the Laws in the country of use and the current standards
GB
in force (UNI - CEI - EN), particularly European standard
EN60335-2-69.

If the version for liquids is used:
■ Make sure that the liquid level sensor operates
correctly before vacuuming liquids.
■ If foam forms, stop the vacuum cleaner
immediately and empty the container.
■ Warning: Switch off the vacuum cleaner
immediately if foam or liquid leaks out.
■ Regularly clean the liquid level limiting device
and check to make sure that there are no signs of
damage.
The dirty liquid collected by the vacuum cleaner must
be considered conductive.

Maintenance and repairs

Disconnect the vacuum cleaner from its power
source before cleaning, servicing, replacing parts or
converting it to obtain another version/variant, the
plug must be removed from the socket.
■ Carry out only the maintenance operations
described in this manual.
■ Use only original spare parts.
■ Do not modify the vacuum cleaner in any way.
Failure to comply with these instructions could
jeopardize your safety. Moreover, such action would
immediately void the EC declaration of conformity
issued with the vacuum cleaner.
