Operation

ON/OFF switch (Fig. 1 / Pos.8)
Switch position 0: Off
Switch position I: On
Dry vacuuming
1. Make sure that a filter bag is mounted when dry
vacuuming.
Wet vacuuming
1. Never vacuum flammable, explosive or caustic
liquids with the device! Make sure that the industrial
vacuum unit is cleaned from building dust before
vacuuming liquids as the industrial vacuum unit may
be strongly damaged otherwise.
2. Always remove the filter bag before starting dry
vacuuming.
3. Empty the tank when it is filled to one third by
opening the cover of the tank and draining the liquid
carefully.
4. The industrial vacuum unit has an automatic switch-
off function, which switches the device off after a
certain fill level is reached. However, this is not the
case for viscose liquids such as certain emulsions,
oils or greases. Therefore, you must check the fill
level regularly during vacuuming in these cases.
5. Switch off the industrial vacuum unit immediately if
liquid or foam penetrates from the housing.
6. Always clean and dry the filter, electrodes and the
tank after vacuuming liquids.
Device socket (Fig.1 / Pos.2)
Your device is equipped with an additional device socket.
You can connect electric tools with a maximum nominal
power of 2000 W with this socket.
Note: The device socket does not have an automatic
function. When using an electric tool, the vacuum must
be switched on manually.

Electrical connection

The installed electric motor is completely wired rea-
dy for operation.
The customer's connection to the power supply sys-
tem, and any extension cables that may be used,
must conform with local regulations.
Important remark:
The motor is automatically switched off in the event of
an overload. The motor can be switched on again after a
cool ing down period that can vary.
Defective electrical connection cables
Electrical connection cables often suffer insulation dam-
age. Possible causes are:
• Pinch points when connection cables are run through
window or door gaps.
• Kinks resulting from incorrect attachment or laying of
the connection cable.
• Cuts resulting from running over the connecting cable.
• Insulation damage resulting from forcefully pulling out
of the wall socket.
• Cracks through aging of insulation.
Such defective electrical connection cables must not be
used as the insulation damage makes them extremely
hazardous.
Check electrical connection cables regularly for dama-
ge. Make sure the cable is disconnected from the mains
when checking.
Electrical connection cables must comply with the regu-
lations applicable in your country.
Single-phase motor
• The mains voltage must coincide with the voltage spe-
cified on the motor's rating plate.
• Extension cables up to a length of 25 m must have a
cross-section of 1.5 mm2, and beyond 25 m at least
2.5 mm2.
• The connection to the mains must be protected with
a 16 A slow-acting fuse.
Only a qualified electrician is permitted to connect the
machine and complete repairs on its electrical equip-
ment.
In the event of enquiries please specify the following da-
ta:
• Motor manufacturer
• Type of current of the motor
• Data recorded on the machine's rating plate
• Data recorded on the switch's rating plate

Cleaning, maintenance and servicing
If it is necessary to consult specialist personnel for
exceptional service tasks or repairs during the war-
ranty period and afterwards, please always contact
a service centre recommended by us or the manu-
facturer.
• Servicing, maintenance and cleaning tasks as well as
repair of functional errors must only be done when the
drive is switched off.
• All protective and safety equipment must be re-moun-
ted after completion of repair and maintenance works.
All air passages and the dust collection container must
be kept clean and must be cleaned regularly using pres-
surised air. Always wear protective goggles when doing
so. Plastic parts should always be cleaned with a soft
and, if necessary, slightly moistened cloth. Do not use
solvents for cleaning. Careful servicing and maintenance
is necessary to avoid deteriorated handling.
Cleaning the electrodes (Fig.9)
Clean the electrodes (18) situated at the bottom of the
tank cover regularly.
