Dust emissions in the environment

Vacuum cleaners can emit different amounts of sucked dust in
the air, depending on the filter they are equipped with. Hereunder
there are some indicative values of the filter performances:
■ Primary filter can retain at least 99.9% of particles.
■ Absolute filter can retain at least 99.995% of particles.

General recommendations

WARNING!
If an emergency situation occurs:
■ filter breakage
■ fire outbreak
■ short-circuit
■ motor block
■ electric shock
Turn the vacuum cleaner off, unplug it and request
assistance from qualified personnel.
WARNING!
The vacuum cleaners must not be used or stored
outdoors.
These vacuum cleaners cannot be used in a corrosive
environment.

This vacuum cleaner creates a strong air flow which is drawn
in through the inlet (5, Fig. 1) and blows out through the
exhaust (4, Fig. 1). After the hose and tools have been fitted,
make sure that the motor turns correctly.
Before turning the vacuum cleaner on, fit the vacuum hose
into the inlet and then fit the required tool on to the end part.
Refer to the manufacturer's accessory catalog or Service
Center. After the hose and tools have been fitted, make sure
that the motor turns correctly.
This vacuum cleaner is supplied with a unidirectional
clapet valve which prevents the vacuum from blowing air
and materials out of the dust container if the wrong phase
sequence is found. If the case, the vacuum cleaner does not
suck any air.
This vacuum cleaner is equipped with an internal baffle
plate which subjects the vacuumed substances to a circular
centrifugal movement that makes them drop into the
container. The vacuum cleaner is equipped with a filter which
enables it to be used for the majority of applications.
Besides the main filter which retains the more common types
of dust, the vacuum cleaner can be fitted with an upstream
and/or a downstream absolute (HEPA) filter with a higher
filtering capacity for fine dust and substances harmful to
health.
