Use
Suction
Switch on the suction with button
(2). The suction output can be regu-
lated in 5 levels. You will see the
selected level in the display. Level 0
would mean that the suction is
turned off.
In case the suction motor over-
heats, the unit will switch off auto-
matically. Leave the unit to cool off
for a while before starting it again.
Should the same failure appear
again, please return the unit to your
supplier for inspection.
Exchange Micro Filter
When changing the filter, it
is advisable to wear a face
mask conforming to EN
14683 type IIR or EN 149 FFP 2.
Only operate the unit with a suction
filter assembled. Control the bag
after every 10 operating hours. Ex-
change a full filter bag immediately.
A filter should be exchanged at
least after 50 operating hours.
At first, unfold the paper of the mi-
cro filter (art. 5179) bag and push
your finger into the opening in the
front.
Pull out the lid of the dust chamber
and remove the old filter. Hold the
filter in the middle to prevent it from
bending and sliding off (see picture
below). Therefore, you avoid it from
coming off again.
The dust filter (art. 5179) must
be used. The paper filter (art.
5115) must NOT be used.
Exchange Control Unit Filter
This filter (art. 3752) has to be ex-
changed after every 200 operating
hours. Remove the old filter and
place the new one in its holder (see
picture below).
