Preface
In this manual you will find
the essentials you need
to know when repairing
wet and dry cleaners of
the Attix 9 series.
When carrying out repairs,
make sure you have a suitable
workbench or the like with the
necessary power supply
available.
If you determine an error
in operation, be sure to
refer the customer to the
user manual.
A fault in the equipment
can have a number of causes.
Chapter E Troubleshooting
will help you here.
Use the illustrated spare
parts lists for your repairs.
These show you the location
of the individual parts and the
sequence in which they are
assembled.
Read the technical informa-
tion sheets. These will tell you
about any technical modifica-
tions made after publication of
this repair manual.
Technical information
sheets are a supplement
to the spare parts list until
a follow-on publication.
Repair manuals and technical
information sheets
should be available at the
site where repairs are carried
out. Further repair
manuals of the Attix series
may be necessary for
repairs to the equipment.
It is not permitted to give
them to third parties.
Use original Nilfisk
ALTO spare parts only!

Safety Issues.
Observe national safety
directives and regulations
for the electrical engineer-
ing
trade, in particular:
IEC 60335-2-69
EN 60335-2-69
DIN VDE 105 part 1:
operation of electrical
power installations.
DIN VDE 0701/0702:
repair, modification and
testing of electrical installa-
tions.
Before starting the equip-
ment,
be sure to read the
accompanying service
manual, and keep it close
as ready reference.
The equipment should
only be used by persons
who have been instructed
in its use and are author-
ized to do so.
Repairs should only be
made by someone who
has received proper
instructions for the job
or who is a qualified elec-
trician.
For your own safety.
ESD (electrostatic discharge)
Observe the following ESD precautions before any
repair of or near electronic parts:
• Touch the protective conductor to discharge your own body.
• Possibly wear an anti-static wrist strap.
• Use a conducting floor or tabletop.
• Never touch a circuit board or electronic components,
always hold them by the plastic or insulation.
• Transport electronic parts in conductive packaging (e.g. special ESD packages).

Function.
Even with extremely fine dust the automatic filter cleaning function allows you to work constantly
with the same suction performance without having to manually clean the filter.
To make it possible to clean the filter during cleaning work, the filter has been divided into two
halves by means of two side seals on the filter holder. The cleaner sucks in dirt through
one side while the other side is being cleaned by a blast of air from the inside to the outside.
One solenoid valve (pos 1.) and the the servo motor (pos.2 ) control ( every 30 sec.) the suction
air stream and the blast of air to clean the filter.
