VACUUM CLEANER FOR
ASBESTOS
On vacuum cleaners with an accessory for the removal of
asbestos dust, the ABS container insert or the protective
bag system must always be used. An exhaust connection
must be attached to the side outlet, through which air can
be exhausted from the working area. The exhaust hose
can be directed to the open air or to a ventilation system
installed in the working area.
The exhaust connection for the air outlet must be fitted
with a 70 mm PUR H hose with a length of < 5 m. This
hose is contained in the Asbestos Kit, which can be
supplied for the machine. As already mentioned, the hose
can either be exhausted directly to the open air or to a
ventilation system installed in the working area.
When transporting the machine you must make sure that
it has been cleaned in accordance with the regulations
stipulated in TRGS 519. The machine can also be
transported in a sealed container from which no
contaminated dust can escape.
Filter replacement
Make sure that the filter is covered with a suitable plastic
bag before it is removed.
Remove the suction pipe “1” from the lower connection.
If the filter assembly is very heavy, remove the upper
cover and lift the assembly from the machine using the two
handles provided. Unscrew the clamp, which attaches the
filter to the basket, and lift the basket from the filter.
Rotate the filter and reveal the plastic strip “2”.
Place the filter in a plastic bag, cut the plastic strip and free
the basket from the filter.
Seal the plastic bag containing the filter.
If the filter is soiled by poisonous or otherwise dangerous
dust do not throw it away. Hand it to an authority, which is
authorised for the disposal of this type of waste.
Take particular care when replacing the main filter or the
complete filter and wear a P3-type mask.
Obtain a filter with the same characteristics as the old filter
and proceed as follows: (Fig. 17).
Fit the filter lock and the sealing ring of the old filter to the
new filter.
Insert the cage “4” and secure the filter using the plastic
strips “2” on the bottom of the filter.
Fit the filter rods in the filter shaking system and tighten the
screw.
Fit the upper cover on the filter unit.
Re-insert the filter unit into the machine.
Re-attach the suction pipe “1” in its original position.
Fix the clamp, which holds the filter unit on the machine.
ABSOLUTE FILTER
HEPA filter “1” must be installed when the vacuum must
operate in clean-room environments, when a high degree
of purity is required or when it must treat materials that are
dangerous for the operator.
This filter is installed in the filter compartment on the top of
machine, between the primary filter and the blower unit.
This allows the machines to achieve 99.995% MPP
efficiency at a particle size of 0.3 Micron, in retaining the
particles that escape the primary filter.
This value was gauged by means of the D.O.P. method.
NOTE
If the machine is to be used for the suction
removal of asbestos dust, either the ABS
container or the protective bag system must
be used.
ATTENTION!
The replacement of the filter is an important
procedure.
The filter must be replaced by another filter
with the same characteristics and the same
filter surface and category. If these rules are
not followed the vacuum cleaner may not
function correctly.
