5.1. Operating field
Depending on the unit configuration, the following functions
and settings are available:
0 = Suction unit >off<
I = Suction unit >on<
A = Ready mode for ON/OFF automatic mode.
(Suction unit is switched ON/OFF by the electrical
tool)
R = Filter cleaning function; in this switch setting the
vibrator is activated for approx. 10 sec. and then
switches off again automatically.
RA = Ready mode like "A" plus automatic filter cleaning.
The power socket
b is available for connecting an elect-
2
rical tool.
Caution! The electrical tool must be switched off during
connection. The power socket is permanently supplied with
voltage when the plug is in the mains socket regardless of the
switch setting. In switch setting "0" the power socket could
still be used as an extension cable (e.g. for lights).
Connected load: Suction unit and connected unit max. 16 A.
The suction output can be adjusted steplessly using the
rotating speed setter
d.

Pre-selection switch
signal (horn and light) for suction units of the
class "M" and "H".
In mode "A" or "RA", the following settings should be made
depending on the diameter of the hose:
Hose diameter
35 mm �
27 mm �
19 mm �
The speed is not regulated.
The suction unit always runs at max. speed
The suction openings of the electrical tools are not standard-
ised. There is an adapter available (rubber nozzle or rubber
muff) which can be shortened and adjusted to the respective
electrical tool.

6.1. Dry suctioning.
Only suction with a dry filter, unit and accessories so that the
dust does not adhere and harden. We recommend using
a paper filter bag if soot, cement, plaster, flour or similar
substances are suctioned.
Always use the paper filter bag in combination with the
filter cartridges.
6.2. Wet suctioning.
Suction without a paper filter bag. The filter cassettes are
suitable for wet suctioning.
The installed sensor switches the motor off when the tank is
full. Empty the unit as outlined in Section 6.4. If the unit is
not switched off, the restarting safeguard remains effective.
The unit will only be ready for operation again after it has
been switched off and switched on again.
Before emptying, first remove the suction hose from the
�
liquid.
Due to the high suction output and the streamlined shape
�
of the tank, a little water may escape from the hose after
the unit has been switched off.
For the subsequent dry suction phase, use a dry filter. In
�
case of frequent changes between dry and wet suctioning,
we recommend using a second filter set, preferably
polyester filter cassettes.
6.3. Cleaning the filter.
The suction unit is fitted with an electro-magnetic filter
cleaning device which can shake off any dust adhered to the
folded filter cassettes.
6.3.1. Manual cleaning.
The vibration function (switch setting R or RA /switch
should be activated at the latest when the volume flow
display
c (warning lamp) lights up or when the warning
2
signal sounds or when the suction output sinks.
6.3.2. Automatic cleaning (automatic vibration).
Filter cleaning is performed (switch setting RA/switch
automatically during the next working break when the mini-
mum volume flow level is reached.
6.4. Emptying the tank.
Only permitted with dusts with AGW's > 1mg/m
