Pre-selection switch ② d for minimum volume 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 Switch setting

Ø 21 mm 20 m³/h
The speed is not regulated. The suction unit always runs at max. speed

When the handle pipe is used, the secondary air valve can be used to adjust the
suction output.
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.
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. 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.
