Nozzle; Adjustment Of Disconnection Wires; Fans - Nederman Magna Track LS Instruction Manual

6.1.3

Nozzle

Insert the nozzle leaf spring in the magnetic unit with the adjusting screw as
shown in Figure 10, item X. Attach the hose on the magnetic unit with the
hose clamp, and cover it with the rubber ring. Check that the nozzle, when not
connected to the vehicle, is pointing forward in the driving direction.
See Figure 10, item X. When the anchor plate has been attached in its correct
position, it is possible to adjust the nozzle by loosening the adjusting screw and
slide the leaf spring some upwards or downwards. Place the nozzle on to the
exhaust pipe, and secure the magnetic unit on the anchor plate making sure the
hose is positioned correctly with a 90° bend to the exhaust pipe, see alternative
1 and 2 in Figure 11.
6.1.4

Adjustment of disconnection wires

The release of the magnet is achieved by means of two wires inside the vertical
hose; one is attached just behind the magnet inside the magnet assembly, and
the other wire on the opposite side inside the magnet assembly. The other ends
of the two wires are attached inside the elbow with the balancer, see Figure 5.
The wires are adjusted at the factory for an installation height of 3,5 m (11 ft - 6
in) of the track.
There is no need for any adjustment of the wires if the track is installed
between 3.3-3.6 m (11-12 ft). If the mounting height is lower than 3.3 m (11 ft),
there may be a reason to shorten the vertical hose and adjust the two wires. See
Figure 5 and the following list:
1. Determine the correct length of the upper hose and cut it, then re-attach
the hose to the elbow and tighten the hose clamp.
2. Loosen the hose clamp on the other side of the elbow and pull off the
lower hose.
3. Loosen the two wire locks on top of the elbow but not more than that you
can slide the wires.
4. Start by carefully pulling the shorter of the two wire ends and observe
the hose at the magnet assembly. Pull the wire until the magnet assembly
is lifted approximately 25-50 mm (1-2 inches), and then tighten the wire
lock for that wire with 3-5 Nm (0.02-0.03lbf/in).
5. Now pull the longer end of the two wires and observe the magnet
assembly. Pull the wire until the magnet assembly is lifted another
50-100 mm (2-4 inches), and tighten the wire lock with 3-5 Nm (0.02-
0.03lbf/in).
6. Reattach the lower hose to the elbow and tighten the hose clamp.
7. Now connect the magnet to the anchor plate and exit carefully while
observing how the system disconnects. Any excessive sling shot of the
system indicates that the wires are not correctly adjusted. Please call a
Nederman representative for guidance.

Fans

Fans are not included in the package.
Position the fan as near the duct outlet from the room as possible to ensure
negative pressure in the ducting system and avoid exhaust leakage.
