USER MANUAL
The filters must be replaced only in proper places (for
example in decontamination stations).

Before replacement, the filter must be wrapped in a
special plastic bag.
Remove the vacuum cleaner motor head. Lift the filter
to remove it from the filtering unit.
Loosen the strap that retains the filter onto the retaining
ring.
Turn the filter upside down until the plastic straps "2"
are exposed. Place the filter in a plastic bag "3"; then,
cut the plastic straps to disengage the cage "4" from the
filter.
Seal the plastic bag containing the filter.
If the vacuum cleaner is equipped with an HEPA filter,
replace it proceeding as follows:
Open the strap retaining the motor head to the filtering
unit. Remove the head to reach the HEPA filter.
Remove the HEPA filter and replace it with a new one.
Reinstall the motor head and close the strap.
