4 Installation
The fume extractor is designed for wall mounting.
1
Ensure that the surface, on which to mount the
arm, is level. Use the wall bracket to mark the
holes (a wall bracket is available as an accessory).
2
Fix the bracket with bolts to the support flange.
3
Fasten the fume extractor on the wall. Use vibra-
tion secured fixing bolts and nuts suitable for the
wall material. Each bolt must stand a torque force
of a minimum of 600 N (130 lbs).
4
Assemble a fan or adaptor for ducting connection
5 Using Telescopic
WARNING! Risk of explosion
The Telescopic arm must not be used for ex-
tracting dust or fume air mixtures in explosive
environments.
WARNING! Risk of fire
Check that no sparks or other objects which can
cause fire are sucked into the arm. For weld-
ing applications generating a high amount of
sparks, spark protection (accessory) must be
mounted in the hood to reduce the risk of fire.
The extraction arm can easily be positioned at any
point within its working area. It can be rotated 180°.
For best capture, the hood should be positioned as
near the fume or dust-generating process as possible.
It has the best suction capacity when it is positioned
according to
.
Always check that the airflow is sufficient in the hood
before work begins. Insufficient airflow is depending
on:
• The fan impeller rotating in the wrong direction.
• Hood, ducting or hose are blocked/damaged.
• Filter cartridges are blocked.
6 Maintenance
All installation, repair and maintenance work must
be carried out by qualified personnel. Contact your
nearest authorized distributor or Nederman for advice
on technical service or if you require help with spare
parts.
NOTE!
The service intervals in this chapter are based
on the unit being professionally maintained.
Recommended at least once a year. Use the necessary
safety equipment.
1
Check that the hoses are intact. Clean the hose if it
is dirty. If necessary, change the hose.
2
Check the mounting of the arm on the wall or ceil-
ing.
3
Adjust the links if necessary, see
.
WARNING! Risk of personal injury
Spring power. Check the function of the
spring and spring holder.
4
Check that the suction capacity in the hood is suf-
ficient.
6.1 Adjusting the links
The joints of the fume extractor are
already adjusted for easy manoeuvrability when the
extension of the arm is at maximum. With a shorter
distance, the upper joint B may need a readjustment.
The lower joint A can be adjusted when necessary dir-
ectly from the opening of the hood, without dismant-
ling the hose. The retraction force of the balancer will
keep the arm in the right position when the desired
range has been set. The retraction force can easily be
adjusted with the knob C on the balancer.
