4 Installation
4.1 90°-bend in hanging or standing po-
sition
The NEX D/DX arm is recommended to be mounted
according to
Figure 4 item A, with the 90°-bend in
hanging position.
The NEX D/DX arm can also be mounted according to
item B, with the 90°-bend in standing position. How-
ever, the arm holder must then be revolved 180°. Re-
volve the arm holder in the following way:
1
Loosen the four screws fitting the arm holder to
the 90°-bend.
2 Move the arm holder approximately 17 mm away
from the 90°-bend.
3 Revolve the arm holder 180°.
4 Move the arm holder back towards the 90°-bend.
5 Fasten the four screws.
4.2 Mounting NEX D/DX
See, Figure 5 – Figure 11 . The extraction arm can be
mounted on wall or ceiling together with a wall brack-
et. Ensure that the surface, on which to mount the
arm, is level and use the wall bracket to mark the
holes.
Use locking fixing bolts and nuts suitable for the wall
material. The bolts much each stand a torque force
of minimum 1200 N (2m), 1900 N (3m), 3200 N (4m),
4500 N (5m). Use a spirit level and make sure that the
extraction arm is fitted in a horizontal position.
Check that proper measures have been taken to avoid
all types of electrical stray currents to and/or from the
piping system and electrical wiring.
NOTE!
Make sure the NEX D/DX housing is properly
grounded. See
Figure 11 and Section 4.3 Earth
control measurement .
NOTE!
Fill out the installation protocol when finished
installing the NEX D/DX.
