4 Initial Operation
4.1 Unpacking
en
⇒ Remove the device and accessories from the package�
⇒ Check the delivery for completeness (compare the list included in delivery)�
4.2 Setting-up
The suction unit is a standing device which must not be operated in a horizontal position�
Place the suction unit so that:
• the exhaust air outlet (11, Fig� 1) is not blocked�
• the front side is easily accessible for removing the dust drawer�
If the suction unit is placed in a closed cabinet, the warm exhaust air must be transported out of
the cabinet using one of the measures shown in Figs. A, B, C at the start of this manual.
• External exhaust air duct (A) (see chapter 4�7)�
• Opening in the cabinet wall (B), min� 250 x 120 mm, directly opposite the exhaust air outlet (11, Fig�1)�
- Distance of the cabinet back side to the wall:
- Distance of the suction unit to the cabinet back side: max. 25 mm.
• Remove the back side of the cabinet (C), distance from the back of the cabinet to the wall min� 50 mm�
If the warm exhaust air is transported out through the openings to the rear, it is essential that the air can
escape unhindered from there�
4.3 Electrical Connection
Before connecting to electricity, ensure that the voltage on the type plate conforms to the local
voltage supply.
Ensure that the layout of live parts (socket, plug and coupling) and extension cables are arranged
so that the protection class is maintained.
⇒ Switch the device off at the on / off switch (3, Fig� 2)�
⇒ Unroll the mains cable (9, Fig�1) and insert the plug into the building's electrical socket�
4.4 Compressed Air Connection
The suction channels are opened and closed by means of pneumatic pinch valves� Compressed air is
required for this� The compressed air tube is securely connected to the side of the device�
For connection to the compressed air network:
⇒ Select the appropriate tube coupling from the supplied connection set (14, Fig� 1) and attach it to the
end of the tube�
⇒ Connect to the compressed air network
Observe the minimum / maximum connection pressure, see technical data!
The compressed air must be clean and dry (no condensation). Moist compressed air can cause
damage to the device!
4.5 Connection to a Suction Point
Warning risk of injury!
When shortening the suction tube, please be sure to cut the
integrated wire as straight as possible.
Long suction tubes, tight bends and kinks greatly reduce
the suction power at the suction point.
When there are different tube lengths, the suction capacity
at the suction points with longer tubes is lower.
Ensure that the suction tubes are the same length and
diameter. Excess length should be shortened or tubes must
be laid in large circles.
⇒ Shorten the suction tubes to the required length for both suc-
tion points�
⇒ Screw the end bushings onto the suction tubes (left turn thread)�
min. 100 mm.
