5.1 Start-up
1.
Check that all joints are adjusted to the correct
friction.
2.
Check the suction tubes for foreign objects.
Remove any such objects immediately.
3.
Check the resistance of the extraction arm with a
calibrated ohmmeter. See
. The resistance
between the measuring points must be less than
1 MΩ.
4.
Check the earth resistance with a calibrated ohm-
meter. See
. The resistance between the me-
asuring points (earth plane/product) must be less
than 1 MΩ.
6 Operation
Ensure that any objects or people that may
be electrostatically charged cannot come into
contact with the equipment.
When extracting different dust combinations,
first ensure that the combination itself is not
an ignition hazard, such as iron filings and
aluminium dust.
Avoid causing an electrostatic charge on
non-conductive dust.
Avoid hygroscopic dust and dust that risks
sticking to the product.
Caution must be exercised with hybrid gas/
dust mixtures as they may prove more
flammable than the separate gas and dust
safety data indicate.
The extraction arm is easily positioned within
the work area by hand. For the best result,
the suction nozzle should be positioned as
close to the contaminant source as possible,
and the result can be further improved if
the suction nozzle rests on a surface
(the so-called Coanda effect).
