Rule 1
The tubes (1) can be installed vertically or horizontally. If the tubes
are installed horizontally, ensure that they slope downwards toward
the vacuum unit.
Rule 2
Always install a short 90° elbow (12) after the socket (10) and the
installation frame (11). This prevents long items from being sucked
in. Note: attach long limb to tube system, and short limb to installa-
tion frame.
Rule 3
Fit the tubes together without adhesive (13) first and check the
distances and flow directions. If possible, route entire tube system,
connect up and check. Start gluing the vacuum sockets when every-
thing is correct.
Rule 4
When checking as described in
rule 3:
Mark the tube connecting posi-
tions
–
At the end of each tube
– On tube elbows that are
different relative angles. If
the elbows are to be at a
relative angle of exactly
45° or 90°, the marks that
are stamped into the tube
elbows can be used.
Rule 5
Always cut tubes at right angles.
Use a tube cutter or a mitre.
Rule 6
Trim sawn or cut edges. Use
a burr-removing knife or sharp
penknife.
