jet fan types AUO/ARO - ARP/AUZ - AUT/ART - AZT
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 installation
footprint. See figure 7 on page 10.
AZT:
Use the ceiling plate as a
drilling rig.
If unapproved expansion bolts
for high temperature are to be
used, these must be made from
steel, must be size M8 or bigger 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 lowering brackets.
Notice:
It is recommended to install
vibration dampers. These
are optional and not
included as standard.
6. AZT: Prepare the ceiling plate for
installation by insertion of four
threaded bolts with washers from the
top in the holes for fan mount.
If applicable, install lowering
brackets in the ceiling.
Mount the ceiling plate in the two
centre holes of the plate. See figure 7
on page 10.
Expansion bolts certified for fire
conditions must be used and
loaded according to the
approval.
Lift the fan in place and fasten it in
the suspension bolts with nuts.
7. Check that the rotor rotates 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 local
legislation, e.g. the EU standard for
electromagnetic compatibility (EMC).
Electric connection
1. Check if current legislation
prescribes installation of f.x. an
emergency stop and include this in
the installation.
2. Remove the lid on the external
terminal box.
3. Connect the motor through a thermal
relay based on the motor nominal
current. Refer to the following
information.
Connection references
• Motor name plate
• Order specification
• Appendix “D. Wiring” on
page 11
Make the connections directly in the
external terminal box.
4. Remount the lid on the terminal box.
4.4 Approval for operation
The installation must be approved with
regard to operation and interaction. The
person responsible for the operation of
the system must initiate this approval
test. The test must be confirmed.
The person responsible for the operation
of the system must keep the approval
test documents. For jet fans approved for
smoke control, the documents must be
