The activated carbon are materials, made predominantly of carbon
in the form of microcrystals of graphite, treated so as to obtain
a porous structure with a large internal surface area. Thanks to
these characteristics they have high capacity adsorbent and are
able to absorb, during the contact phase, many types of substan-
ces, attracting the molecules in their inner surface. The absorbent
capacity of the filter is given by the types of pollutants and from
their combination.
For the replacement of carbon filters, unscrew the side vents on the
sides, on which are threaded, as shown above.
You have to pull out the old filter from the grill then insert the new one.
* The fourth filtration stage is only with the Active Carbon Kit, when
not present, as in the standard version, there is a polyester microfiber
panel in order to reduce noise emission.
CAUSE
Reduced supply voltage
Lack of power
Lack of power
Engine burned
Clogged filters beyond the
established limit
The motor runs below its normal
rotation speed
Imbalances of the rotating parts Check the balancing of the rotating
Loose or unsuitable vibration
dampers
It is recommended to clean this filter at least
once a year for maximum efficiency of the
machine.
Carbon filters are made with inert materials
which, if they are not contaminated with
toxic-noxious substances deriving from their
use, can be disposed of as solid urban waste.
REMEDY
Check the motor plate data and the
mains supply
Check the connection of the plug
and / or the power socket
Check the connection of the plug
and / or the power socket
Replace the vacuum cleaner
Remove the filters and clean them
with compressed air
Replace the filters
Replace the pressure switch
Check the supply voltage. Check
the motor winding for defects and
replace it if necessary.

Check the correct tightening of the
anti-vibration mountings and their
integrity
