If there are any damaged or missing parts when the
product is delivered, notify the carrier and the local
Nederman representative immediately.

See Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 .
The extractor arm can be mounted on a wall, bench,

er with the accessories wall/ceiling bracket, hood and

See Figure 8 . The arm must always be mounted so
that the adjusting knobs on the links are on the right-
hand side.
If a UP-arrow is positioned near the duct connect-
or, the arm must only be installed so that this arrow
points upwards.
NOTE!
The extractor arm must be connected to the
earth according to
Figure 10 . The combina-
tion of extractor arm and extraction system
must be carried out in accordance with require-
ments of explosion prevention and protection
EN 1127-1.
See Figure 9 . Make sure the arm and the duct are

See Figure 10 . Earth control measurements must only
be done by a person with appropriate competency of
explosion protected installations.
If a hood (accessory) is used the measuring should be
done from the hood. The ohmmeter must indicate less
than 106 Ω.

• If necessary, use a serrated washer to make
sure there is conductivity.

5.1 Arm position
See Figure 13 . Always place the arm as close as pos-
sible to the source. When possible, place the arm side-
ways to the source for best capture, to avoid interfer-
ing with the work process, and to minimize the effect
of the cross draft. See
Figure 13 (A).
Always check that the airflow is sufficient in the hood
before work begins. Insufficient airflow can be due to:
• The fan impeller rotates in the wrong direction.
• Hood, arm or ducts are blocked.
For adjustments of damper, swivel and link, see Fig-
ure 12 (A).
