1. Plug the mains plug into the socket.

2. Switch on the device via the suction tur-

bine power switches. Note Always switch the suction turbines on and off one after the other. For the correct func- tion of the pressure gauge for monitoring the minimum volume flow, all suction tur- bines must be switched on. Note In most application cases it is sufficient that you vacuum with one suction turbine. If24 English necessary, switch on the 2nd suction tur- bine. However, do not operate the device with both suction turbines for longer than 15 min. This can cause too much humid air to prematurely wet the main filter. If neces- sary, let the main filter dry afterwards or re- place it (see chapter Replacing the main filter).

3. Start the vacuuming process.

Performing the vacuuming process

1. Regularly check the filling level in the dirt

receptacle, since the device does not switch off automatically. Note The device is equipped with a mechanical monitoring unit. This monitoring unit inter- rupts the airflow when the inert liquid falls below the minimum filling level. Refill with inert liquid to continue the vacuuming pro- cess (see chapter Fill the dirt receptacle with inert liquid).

2. Make sure that no more than 8 litres of

material are sucked in during vacuum- ing.

chapter Replacing the main filter). Note If the dirt receptacle is filled with an inert liq- uid, moist air may flow through the main fil- ter during suction and soak it. Check the main filter for moisture after the vacuuming process. If necessary, let the main filter dry or replace it (see chapter Replacing the main filter). Reading the minimum volumetric flow A pressure gauge showing the vacuum in- side 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 Replacing the main filter). This value depends on the device performance and the suction hose used. If the vacuum is not significantly reduced by replacing the filter, there must be another problem (see chapter Troubleshooting guide). 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. Replace the filter. Switching off the device
