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.
