Variants
ATEX
The manufacturer produces vacuum cleaners suitable to be
used in potentially explosive atmospheres. These variants are
manufactured according to directives and standards in force.
The relevant additional instructions are supplied together with
the device.
In the Class M and H version, this vacuum cleaner can also
be produced as Variant ATEX.
[ NOTE ]
ATEX variants
Refer to the manufacturer’s sales network for these
versions.
For ATEX industrial devices see the instructions for “ATEX”
use.

immediately and check for the cause.
Versions
WARNING!
Classes of dustiness.
This vacuum cleaner is produced in two versions:
1. normal version: not suitable for vacuuming
hazardous, combustible/explosive dust;
2. version for dust harmful for the health: classes
L - M - H. In this case, the vacuum cleaner is
suitable for use with hazardous, noncombustible/
explosive dust in accordance with standard EN
60335-2-69, par. AA. 2. 202 b), c).
Check on the data plate and on the label applied
to the vacuum cleaner to ascertain the tolerated
dust hazardousness class: L (low risk), M
(medium risk), H (high risk).
Classication in compliance with standard
EN 60335-2-69 - Annex AA
Appliances for dust that is hazardous for the health are
classied according to the following dust categories:
■ L (low risk) suitable for separating dust with an exposure
limit value of over 1 mg/m3, depending on the volume
occupied;
■ M (medium risk) for separating dust with an exposure
limit value of over 0.1 mg/m3, depending on the volume
occupied;
■ H (high risk) for separating all dusts with an exposure
limit value of less than 0.1 mg/m3, depending on the
volume occupied, including carcinogenic and pathogenic
dusts.
Dust emissions in the environment
Indicative values of performance:
■ normal version (not suitable for vacuuming hazardous
dust): retains at least 99% of the vacuumed particles
(see EN60335-2-69, Annexe AA);
■ version for dust harmful to health (L, M, H classes):
L: retains at least 99% of the vacuumed particles
(see EN60335-2-69, Annexe AA);
M: retains at least 99.9% of the vacuumed particles
(see EN60335-2-69, Annexe AA);
H: retains at least 99.995% of the vacuumed
particles (see EN60335-2-69, Annexe AA).

“Shaking the main lter”).
L. Exhaust
M. Panel power plate
Indicates that the panel is powered by the voltage given
on the data plate.
N. Attention plate (voltage)
For this reason, only explicitly authorized personnel must be
allowed access to the panel.
The electrical components must only be accessed after the
power supply has been disconnected by setting main switch
“D” to position -0- (o) and after having removed the plug from
the current socket.
This vacuum cleaner creates a strong air ow which is drawn
in through inlet “F” and blows out through exhaust “L”; after
the hose and tools have been tted, make sure that the motor
turns in the right direction.
Before turning on the vacuum cleaner, t the hose into the
inlet and then t the required tool on to the end part. Refer to
the accessory catalogue or the assistance service.
Only use genuine antistatic accessories.
The diameters of the authorized hoses are given in the
technical specications table.
This vacuum cleaner is equipped with an internal deector
which subjects the vacuumed substances to a circular
centrifugal movement that makes them drop into the
container.
The vacuum cleaner is equipped with a main lter which
enables it to be used for the majority of applications.
Dierent types of main lter are available: standard and class
L and M for dusts that are hazardous for the health.
Besides the main lter which retains the more common types
of dust, the vacuum cleaner can be tted with a secondary
lter (Hepa H) with a higher ltering capacity for ne dusts and
substances that are hazardous for the health.
Optional kits
Various optional kits are available for converting the vacuum
cleaner:
■ level gauge for liquids - stopping liquids;
■ removable separator;
■ clamp and bracket;
■ downstream Hepa lter;
■ grill and depressor;
■ grate;
■ cartridge lter;
■ electric lter shaker;
■ limiting valve.
On request, the vacuum cleaner can be supplied with optional
kits already installed. However, they can also be installed at a
later date.
Please contact the sales network for further details.
Instructions describing how to t the optional kits and the
relative operation and maintenance manuals are supplied
together with the optional kits themselves.
WARNING!

WARNING!
When the device is operating, do not:
■ Crush, pull, damage or tread on the cable that
connects to the electrical mains.
■ Only disconnect the cable from the electrical
mains by removing the plug (do not pull the
cable).
■ Only replace the electric power cable with one of
the same type as the original: H07 RN-F, the same
rule applies if an extension is used.
■ The cable must be replaced by the manufacturer’s
Service Centre sta or by equivalent qualied
personnel.
Extensions
If an extension cable is used, make sure it is suitable for the
power input and protection degree of the vacuum cleaner.
WARNING!
Variant ATEX: extensions, plugged-in electrical
devices and adapters cannot be used when the
vacuum cleaner is used for ammable dusts.
Minimum section of extension cables:
Maximum length = 20 m
Cable = H07 RN-F
Max power (kW) 3 5 15 22
Minimum sect. (mm2) 2.5 4 10 16
WARNING!
Sockets, plugs, cable clamps, connectors and
installation of the extension cable must maintain the IP
protection degree of the vacuum cleaner, as indicated
on the data plate.
WARNING!
The vacuum cleaner’s power socket must be protected
by a dierential circuit-breaker with surge current
limitation, that shuts o the power supply when the
current discharged to the ground exceeds 30 mA for
30 msec. or an equivalent protection circuit.
WARNING!
Never spray water on the vacuum cleaner: this could
be dangerous for persons and could short circuit the
power supply.
WARNING!
Comply with the safety regulations governing the
materials for which the vacuum cleaner is used.

Setting to work - connection to the power
supply
WARNING!
■ Make sure there is no evident sign of damage to
the vacuum cleaner before starting work.
■ Before plugging the vacuum cleaner into the

indicated on the data plate corresponds to that of
the electrical mains.
■ Plug the vacuum cleaner into a socket with a
correctly installed ground contact/connection.
Make sure that the vacuum cleaner is turned o
(VHW311T version).
■ The plugs and connectors of the connection
cables must be protected against splashes of
water.
■ Check that for proper connection to the electrical
mains.
■ Use the vacuum cleaners only when the cables
that connect to the electricity mains are in perfect
condition (damaged cables could lead to electric
