It is essential for the
performances and sound levels
that the airflows are unimpeded
and free from eddies.
2.
Drill holes in the ceiling in
accordance to the mounting
specifications. See figure 3 and table
5.
If unapproved expansion bolts
for high temperature are to be
used, these must be made from
steel, must at least be size M8 and must
be mounted twice as deep as
recommended – at least 60
mm deep.
The static load must not exceed a pull of
more than 500 N.
3. Optional:
Install lowering brackets
in the ceiling, if applicable.
4.
Place the fan on a platform that can
be raised, for example a scissor lift.
5. AUO/ARO-ARP/AUZ-AUT/ART:
Fasten the fan in the suspension
points to the ceiling or, if applicable,
to the lowering brackets.
Notice:
It is recommended to install
vibration dampers. These
are optional and not
included as standard.
6. AZT:
Mount the base plate to the
ceiling or. if applicable, to the
lowering brackets and install the
vibration dampers.
Expansion bolts certified for fire
conditions must be used and
loaded according to the
approval.
Lift the fan in place with attention to
the correct insertion of the bolts,
which must enter and slide back in
the base plate slits.
7.
Check that the rotor rotate freely in
the fan casing.
8. AUO/ARO-ARP/AUZ:
Remove the
transport brackets on the underside
of the fan casing. Reinsert the screws
from the brackets in the casing.
AZT:
Reinsert the screws from the
transport brackets in the casing.
4.3 Electric connection
The installation and connection
to the supply network must be
done by authorised personnel
and according to current legislation,
e.g. the EU standard for
electromagnetic compatibility (EMC).
