Compressed Air Connection

The extraction unit requires compressed air for the following reasons:
• To open and close the pneumatic pinch valves,
• For the automatic filter cleaning function.
On the device, the compressed air tube is sealed (9, Fig. 1).
⇒ Connect the compressed air tube with assembled coupling to the compressed air supply.
Observe the minimum / maximum connection pressure; see section 8.1, Technical Data!
Do not change the coupling fitting on the compressed air tube for a smaller version!
The compressed air must be clean, dry (no condensation) and free from oil. Moist compressed air
can cause damage to the appliance!
The compressed air supply tube leading from the compressor to the appliance should be no less
than 10 mm in diameter.

Connection to the Extraction Point

The extraction point is at the extractor connection
fitting (7).
The items "pinch valve and suction ports" are rotatable.
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 suction ports are marked with the letters A, B, C, D
on the compressed air tubes, so that the suction chan-
nels can be easily allocated.
⇒ As required, turn the pinch valve with the suction
port (7) into the correct direction.
⇒ Insert the suction tube (8, not contained in delivery)
into the suction port (7).
If the diameter of the tube does not fit accurately, use
a tube connection adapter (see accessories) to pre-
vent background extraction noise and loss of suction.
⇒ Attach the suction tube to the relevant suction point
(e.g. Dustex master plus, suction hood, etc.).
In order to achieve a good, even suction perfor-
mance, the suction tubes should be approximately
the same length and no longer than 3 m.
Long suction hoses, tight bends and kinks will
considerably reduce the extraction force at the ex-
traction 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.

Quattro Control-Box (= QCB)

With the QCB (15) it is possible to switch the suction on
and off and to activate and deactivate relevant suction
channels depending on the requirements of the dust gen-
erating electrical appliances.
Up to four different electrical appliances can be connect-
ed to the appliance socket connections (16) at the QCB.
When the electrical appliance is activated, the relevant
suction channel opens.
The appliance socket connections (16) are marked with
the letters A, B, C, D so that the suction channels can be
easily allocated.
