How To Disassemble And Replace The Main And Hepa Filters; Primary Filter Replacement - Nilfisk-ALTO ATTIX 130 Betriebsanleitung

The suitable precautions include decontamination
before disassembling the vacuum, adequate
filtered ventilation for the air exhausted from
the room in which it is disassembled, cleaning
of the maintenance area and suitable personal
protection.
b) The external parts of class H and class M appli-
ances must be decontaminated by cleaning and
vacuuming methods, dedusted or treated with
sealant before being taken out of a hazardous zone.
All parts of the appliance must be considered as
contaminated when they are removed from the
hazardous zone and appropriate actions must be
taken to prevent dust from dispersing.
When servicing work or repairs are carried out, all
the contaminated elements that cannot be cleaned
well must be eliminated.
These elements must be disposed of in sealed
bags conforming to the applicable regulations
and in accordance with the local laws governing
the disposal of such material.
This procedure must also be followed when the
filters are eliminated (main, Hepa and downstream
filters).
Note: Compartments that are not dust-tight must
be opened with suitable tools (screwdrivers,
wrenches, etc.) and thoroughly cleaned.
c) In addition, the filtering effectiveness of class H
appliances should be checked at least once a year
or even more often if so specified by national law.
The filtering effectiveness of the appliance can be
tested following the testing procedure explained
in the norm DIN EN 60335-2-69 AA.22.201.2. If the
outcome is negative the test has to be repeated
with a new primary filter.
d) ATTENTION: this appliance contains powders that
are harmful for one's health. All maintenance work
and emptying, including removing the powder
from the container, must be done by specialized
personnel only and they must wear protective
clothing. Do not start without the complete filtering
system in place.
e) This appliance is not to be used by people (inclu-
ding children) with physical or sensorial problems
or mental difficulties or with little education and/or
knowledge who must always be supervised by
skilled people or be instructed by them on how
to use the appliance.

ATTENTION DANGER !
When the vacuum cleaner is used to clean up hazar-
dous substances, the filters become contaminated,

- work with care and avoid spilling the vacuumed
dust and/or material;
- place the disassembled and/or replaced filter in a
sealed plastic bag;
- close the bag hermetically;
- dispose of the filter in accordance with the current laws.
ATTENTION DANGER !
Filter replacement is a serious matter.
The filter must be replaced with one of identical cha-
racteristics, filter surface and category.
Failing this, the vacuum cleaner will not operate correctly.
