NEX S
5 Use
WARNING! Ignition risk for some dust or
solvents
• Do not collect material that is caustic, explos-
ive, highly flammable, chemically unstable,
spontaneously ignitable, or which can re-
lease sparks.
• Check that no objects which can cause spark-
ing or fire are sucked into the arm, or impact
against the hood.
• Avoid mixing dust from different processes,
for example, service works and plastic grind-
ing mixed with metal grinding.
WARNING! Risk of personal injury
Squeeze risk. See
Figure 4b .
CAUTION! Risk of equipment damage
Avoid impact against the hood.
See Figure 9 . The extractor arm can easily be posi-
tioned at any point within its working area, using the
handle (item A). It can be rotated 180° when wall
mounted and 360° when ceiling mounted. For best
capture, the hood should be positioned as near the
fume or dust-generating process as possible.
Recommended airflow (also, check local directions):
• Maximum 1100 m
3
/h (650 cfm) for hose Ø 125 mm.
• Maximum 1700 m 3
/h (1000 cfm) for hose Ø 160
mm.
Always check that the airflow is sufficient in the hood
before work begins. Insufficient airflow is caused by:
• The fan impeller rotating in the wrong direction.
• Hood or hose are blocked.
• Filter cartridges are blocked.
