4 Installation
4.1 90°-bend in hanging or standing position
The NEX D/DX arm is recommended to be mounted according to Figure 4,
item A, with the 90°-bend in hanging position.
In exceptional cases the arm can be mounted according to item B, with the
90°-bend in standing position. However, the arm holder must then be revolved
180°. Revolve 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 Figures 5–11. The extraction arm can be mounted on wall or ceiling
together with a wall bracket. 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.
4.2.1 Rotary stop
Should only be fitted when the arm is mounted in a 360° rotating position, see
Figure 5.
