4. Setting Up
4.1 Unpacking
⇒Remove the device and all the accessories from the delivery package.
⇒Check the delivery for completeness (refer to the “Scope of Delivery” section).
4.2 Setup
Theextractionunitisafree-standingappliance,intendedtobeset-upontheoor(e.g.underthework-
bench).
It is possible to connect up to two suction points.
Positiontheextractiondevicesothat:
• The exhaust vent (14, Fig. 1) is not blocked.
• The distance to the suction points is approximately even.
• The front of the device is easily accessible for removal of dust drawer.
If the device is to be installed in a cabinet, an opening for the exhaust air with the following dimensions
mustbeprovided,inadditiontotheopeningsforthesuctionhoses:
• Circularopening: Min.120mmdiameters
• Rectangularopening: Min.170x65mm
4.2.1 External Exhaust Air Route
An external exhaust air route (see accessories) allows the extracted air to leave the laboratory.
The installation details are supplied with the external exhaust air route.
When the extraction unit is used in conjunction with an external ventilation system, a signi-
cant quantity of air is extracted from the room per hour.
This can create negative pressure within the room which, when using an air dependent naked
ame fed by gas, liquid or solid fuel, can cause poisonous gasses (e.g. carbon monoxide) to be
drawn into the working area.
It is therefore essential to ensure that the fresh air supply is sufcient and that the environmen-
tal air pressure is maintained, this should then be monitored by an authorized specialist (e.g. a
certied Gas Service Engineer).
4.3 Electrical Connection
Before connecting the device, ensure that the voltage information on the identication plate
corresponds with your local power supply.
Arrange the conducting parts (plug sockets, plugs and couplings) and install the extension
cord so that the protection class is retained.
⇒Switch the device off at the on / off switch (3, Fig. 1).
⇒Insert the mains cable into the plug socket.
4.4 Compressed Air Connection
The suction hoses are opened and closed via the pneumatic pinch valves (15, Fig. 3).
For this, compressed air is necessary. On the device, the compressed air tube is sealed.
Connectiontothecompressedairsupply:
⇒Select the appropriate tube connection piece from the connection set (17, Fig. 1) and attach to the
end of the tube.
⇒Connect to the compressed air.
Observe the minimal / maximum connection pressure, see technical data!
Compressed air should be clean and dry (without condensed water). Wet compressed air can
damage the unit.

4.5 Installing the Pinch Valves
In order to prevent damage during transport, the following parts
- pinch valves (15)
- suction pipe (16)
- holder (20)
are not mounted on the device, but will be delivered in a
pre-assembled state.
⇒Thesemustbeinstalledontothedevicebeforeuse:
⇒Unscrew the knurled head screw (19, Fig. 4a).
⇒Push the suction pipe (16) onto the suction support on the
extractor and hang the holder (20) onto the holder screws
(26, Fig. 4b).
⇒Fix the holder in place with the knurled head screw
(19, Fig. 4a).
⇒Connectthecompressedairtubestothepinchvalves:
- Ensure the compressed air tubes (A, B) are connected to the correlating suction pipes (A, B).
- Push the compressed air tube onto the pipe connection in the pinch valve as far as it will go.
There will be a slight resistance to overcome when attaching.
4.5.1 Suction Pipe Alteration
During the alteration, make sure that the compressed air tube is not unintentionally ripped
away from the pinch valves. If possible, loosen before the alteration (press the ring at the
compressed air connection and pull the tube towards you) and tighten again after the work has
nished.
⇒Pull the pinch valves (15, Fig. 3) out of the suction pipe (16, Fig. 3).
⇒Unscrew the knurled head screw (19).
⇒Loosen the suction pipe and the holder (20) from the holding screws (26)
byturningandthenattheback,removefromtheextractorconnectiontting(A).
⇒Lever the suction pipe out of the holder (B), turn (C), and replace back into a
new position in the holder (D).
⇒Insertthesuctionpipeintotheextractorconnectionttingontheextraction
device, hang (E) the holder into the holding screws (26).
⇒Fix the holder with the knurled head screw (19).
⇒Push the pinch valve into the suction pipe as far as it will go.
This process is made easier by turning slightly when pushing into place.
4.6 Connection to the Extraction Point
Theextractionpointisattheextractorconnectiontting(15).
When you turn the pinch valve, please ensure that there are no kinks in the compressed air
tubes and that they are not unintentionally ripped off!
The compressed air tubes are marked with A and B so that they can
be easily allocated to the relevant suction hoses.
⇒Shorten the suction pipes for both extraction points to the required
length with a knife.
⇒Screw the PVC end bushings onto the suction pipes (left handed
thread).
Caution: Risk of injury!
When shortening the suction pipe please ensure to cut at a right
angle.
⇒Insertthesuctionhose(18)intotheextractorconnectiontting(15).
Please use a hose connection adapter (see accessories) if the diameter sizes are different, in order
to minimize ambient noise and loss of extraction force.
⇒Attach the suction hose to the extraction point (e.g. Dustex master plus, extractor clamp, etc.).

Long suction hoses, tight bends and kinks will considerably reduce the extraction force at the
extraction point.
If different suction hose lengths are used, the extraction force will be lower at the extraction
point with the longer hose.
Make sure that the suction hoses are the same length and diameter. Excess hose can be cut to
size or laid in a large arch.
Avoid steep pitches or hanging points along the hose path.
4.7 Electrical Connection
⇒Electrical appliances can be connected to the coupler sockets (9, Fig. 1) at the back of the unit.
Check the connections are correct - coupler socket (A, B) - suction hose / pinch valve (A, B).
When connecting electrical appliances to the extraction unit, please ensure that the power con-
sumption of all devices connected to the unit power outlet does not exceed the total maximum
power for connected equipment (see chapter 8, “Tech. Data”).
A two pole plug with protective contact is available for use as an adapter. This adapter may only
be put together by an electrician!
The protective conductor system must not be interrupted by the adapter!
5. Operation
The extractor unit is operated via the buttons on the key-pad (2, Fig. 1).
5.1 Switching the Unit On

5.2 Operation
5.2.1 Extraction
When the extractor is switched on it goes to the stand-by mode.
When a suction hose is opened, the suction turbine switches to the last selected extraction force and
the correlating pinch valve opens. When the second suction hose is then opened, the second pinch
valve also opens.
Opening/closingofthesuctionhoseisasfollows:
• Automatically:
The electrical appliance connected to the coupler socket (9, Fig. 1) is activated / deactivated.
• Manually:
By pressing a suction hose button (39).
The letters of the opened suction hose will be shown in the display (38).
If the electrical appliance is active, the relevant suction hose CANNOT be closed manually with the
suction hose button, instead only by switching the electronic equipment off.
5.2.2 Extraction force
The extraction force can be adjusted in three levels; the current
extraction force is shown in the display (37).
Settheextractionforce:
• Button (43), increases extraction force
• Button (41), reduces extraction force
Readjustment of the extraction force:
The set extraction force applies for both suction hoses. When
another suction hose is opened or closed, the power in the
suction turbine is automatically readjusted so that the selected
extraction force may be achieved in each opened suction hose.
To deactivate the extraction force readjustment:
Inthestand-bymode:
⇒Press / buttons (43/41) together for 3 seconds.
♦The indicator above the button (41) shows “OFF”.
The deactivated extraction force readjustment is shown by the “OFF” indicator above the button (41)
permanently.
To activate the extraction force readjustment:
Inthestand-bymode:
⇒Press / buttons (43/41) together for 3 seconds.
♦The indicator above the button (41) goes “OFF”.
When the extraction force readjustment is deactivated, the extraction power on one suction
hose will reduce considerably if a second suction hose is then also activated.
On extraction force level “3” with both hoses open, only a reduced extraction power is available
as the suction turbine cannot be increased any further.
The fuller the dust bag, the lower the extraction performance.

6.3 Self-Diagnosis
If the self-diagnosis is activated (see chapter 5.3.1), it will take place when the device is switched on.
It checks important functions in the device.
This process takes approximately 30 seconds.
A blocked or defect suction hose can only be detected by the self-diagnosis and not when the
device is in action.
If an error is detected during the self-diagnosis, a fault code (see chapter 7.1) will be displayed.
Please continue as instructed.
6.4 Safety Mechanism
The extractor is safeguarded by two device overload switch-
es (10).
If an overload switch is released, it can be reset by pressing
the button back in.
If the protection switch is repeatedly released, this shows
the device has a fault.
Send the device to be repaired!
