Operation
Danger
The dust extractor is not suitable
for extracting dusts that are
hazardous to health.
5.1
Switching on and off
Switch positions for IV operation (industrial
vacuum cleaner) (fig. 1)
0 = Off
I
= On (manual operation)
The volume flow display is switched over to
a fixed value which causes the signal lamp
to blink if the air speed drops below 20 m/s.
A = Stand-by mode for automatic switch on/off
function (dust extractor is switched on and
off by the electrical tool).
Switch positions for DED operation (deduster) Fig.
1
RA = Device models with “RA” equipment can
be operated as under “A”. Filters are
cleaned automatically on reaching the set
minimum flow rate during the next work
break (switch position RA).
The dust extractor S 25 M / S 25 L is equipped with
an electronic suction force regulator.The turning knob
2 can be used to adapt the suction power to the
material to be vacuumed.
The socket outlet 4 is provided for the connection of
an electrical tool (A/RA mode).
Danger
The electrical tool must be
switched off when it is connected.
When the power plug is plugged in,
the socket outlet is always live,
irrespective of the switch position.
In switch position "0", the socket
outlet can be used as extension
cord (e.g. for lamp).
Connected load: Dust extractor and
connected device max. 16 A.
To avoid excessive start-up peaks, the dust extractor
is equipped with a starting current limit (soft start).
Danger
While the dust extractor motor is
coasting down, the operating mode
selection switch may not be turned
until the dust extractor has come to
a standstill, otherwise the device
must afterwards be switched via
the 0-position to guarantee the
perfect functioning of the electronic
system.

Hints and information
-
When vacuuming dry materials, the folded filter 5
(fig. 2) must be completely dry.
-
During wet vacuuming, the built-in sensor prevents
the maximum filling level in the container from
being exceeded. The device no longer vacuums
when the container is full. Switch off motor. Pull the
dust extractor plug and empty the container.
-
If the sensor responds when vacuuming larger
amounts of liquid (more than one container filling),
switch off the device and empty the container.
-
If the volume flow display 3 (fig. 1) lights up on
restart, this may have the following reasons:
-
Container, filter bag 8 (fig. 4) full.
-
Extraction hose clogged.
-
Air cross sections of the dust generator too
small.
On completion of work, but especially if you do not
intend to use the device for a longer period of time,
you should:
