Absolute Filter; Categories Of Use - Nilfisk Advance IV 022 Mode D'emploi

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.
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.
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
strip "2" on the bottom of the filter.
Fit the filter rod 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.
