Mounting NEX S

See Figures 4–8. The extractor arm can be mounted on a wall. Ensure that the
wall surface is level, and use the wall bracket to mark the holes.
Use locking fixing bolts and nuts suitable for the wall material. The
bolts must each stand a minimum torque force of: 1100 N (NEX S 2 m),
2400 N (NEX S 3 m), 4000 N (NEX S 4 m).
Use a spirit level and make sure that the extraction arm is fitted in a horizontal
position.
NOTE! Make sure the NEX S housing is properly grounded. See figure 8 and
section 4.3 Earth control measurement.
NOTE! Fill out the installation protocol when finished installing the NEX S.
