The device is suitable for vacuuming dusts up to dust class H.
WARNING: This device contains dusts that are harmful to your health. Emptying and maintenance, including removal of the dust bag, may only be performed by appropriately trained personnel wearing suitable personal protective equipment. Do not switch on until the entire filter system has been installed and the volume flow control functionality has been checked.

The unit is suitable for vacuuming combustible dusts, installation outside zone 22.
WARNING: This unit must not be placed in any zone 22. If a zone 22 is present, an EX-device must be used.

DN 40      MAX       XX,X kPa/ XX,X mbar
DN 50      MAX       XX,X kPa/ XX,X mbar
DN 70      MAX       XX,X kPa/ XX,X mbar

The maximum vacuum value in relation to the hose cross-section is specified on the label. The actual value can be read on the pressure gauge. For the values applicable to this device, see chapter Reading the minimum volumetric flow. If this value is not reached, the filter must be cleaned (see chapter Dedusting the main filter) or replaced (see chapter Replacing the main filter). The various different hose cross-sections allow adaptation to the various different connection cross-sections of the accessories.

Ending wet vacuum cleaning

  WARNING
Improper disposal of waste water
Environmental pollution
Observe the local waste water treatment regulations.

1. Dry the filter.
2. Clean the dirt receptacle with a moist cloth and dry it off.

Switching on the device

1. Plug the mains plug into the socket.
2. Switch on the device via the suction turbine power switches.

Note
Always switch the suction turbines on and off one after the other. For the correct function of the pressure gauge for monitoring the minimum volume flow, all suction turbines must be switched on.

3. Start the vacuuming process.

Reading the minimum volumetric flow

A pressure gauge showing the vacuum inside the device is mounted on the front of the device. The main filter must be cleaned when the maximum vacuum (see table) is reached (see chapter Dedusting the main filter). This value depends on the device performance and the suction hose used. If the vacuum is not significantly reduced by dedusting, the filter must be replaced (see chapter Replacing the main filter).

ATTENTION
Exceeding the maximum vacuum
Suction loss
If the specified value is exceeded, the air speed in the suction hose drops below 20 m/s. Clean or replace the filter.

WARNING
Danger from dust that is harmful to your health
Respiratory sicknesses through inhalation of dust.
Safety devices providing hazard protection must be checked for correct safety- related functionality at least annually by the manufacturer or an appropriately instruction person, e.g. absence of leaks, filter damage, functionality of the monitoring devices.

ATTENTION
Care agents containing silicone
These can attach plastic components.
Do not use care agents containing silicone for cleaning.
Dust extraction machines are safety devices for the prevention or elimination of hazards according to the German BGV A1.

• For servicing performed by the user, the device must be disassembled, cleaned and maintained only to the degree that this is possible without presenting a danger to the maintenance personnel and other persons. Suitable precautionary measures include detoxification before disassembly. Make provisions for local forced ventilation at the location where the device is to be disassembled, for cleaning the maintenance surface and to ensure adequate protection for the personnel.
• The exterior of the device should be detoxified by vacuuming and wiped clean, or treated with sealant before being removed from the hazardous area. All unit parts must be regarded as contaminated when they are taken from the hazardous area. Suitable measures must be taken to prevent distribution of the dust.
• All contaminated objects resulting from maintenance and repair work that cannot be satisfactorily cleaned must be correctly disposed of. Such objects must be disposed of in sealed bags in accordance with the applicable regulations for the disposal of this type of waste.
• The suction hose ports are to be closed using the sealing plugs during transport and maintenance of the device.

1. Note that you can carry out simple maintenance and care work yourself.
2. Clean the surface of the device and the interior of the container regularly with a moist cloth.
3. Carry out a regular visual inspection for clogging of the hoses.
