INSTALLATION, USE AND MAINTENANCE MANUAL
4.2 Manual filter cleaning
The main vacuum unit has a filter cartridge that filters dust, protection the vacuum motor.
It is important to make monthly checks on the condition of this filter.
On models with the Self-cleaning function, annual inspections must be made on the filter to ensure that it
is undamaged and to check if it needs washing (if washed, the filter must be dry before being replaced).
It is advisable to keep a spare filter available for cleaning operations.
INSTRUCTIONS
ATTENTION: Before carrying out any work on the filter cartridge, it
is compulsory to unplug the unit from the 230 V power supply wall
socket.
ATTENTION: Do not use compressed air. The filter must be replaced after
three years of standard use.
1. Unplug the unit from the 20 V power supply wall
socket.
2. Release and remove the dust container.
. Unscrew and remove the filter retention ring (fig. 1).

. Replace with the spare filter, r
esting it against
the ring, and screw it fully in.

correctly.

No maintenance is necessary for vacuum pipes, as the suction power of the
system ensures that these are kept constantly clean.
Do not use the main vacuum unit
without the filter.
