10.6 WARNING: SPECIAL PRECAUTIONS
"WARNING - TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, OR INJURY TO PERSONS, OBSERVE THE FOLLOWING":
- "Installation work and electrical wiring must be done by qualified person(s) in accordance with all
applicable codes and standards, including fire-rated construction."
- "When cutting or drilling into wall or ceiling, do not damage electrical wiring and other hidden utilities."
- "To Reduce The Risk Of Personal Injury, Do Not Bend The Blade Brackets When Installing The Brackets,
Balancing The Blades, Or Cleaning The Fan. Do Not Insert Foreign Objects In Between Rotating Fan Blades."
- Be sure power is off before attempting installation
- After making the wire connections, the wires should be spread apart with the grounded conductor and
the equipment-grounding conductor on one side of the outlet box and the ungrounded conductor on the
other side of the outlet box.
The installer and the building owner are responsible to ensure the safety of the fan mounting system and that
the fan installation is correct, in compliance with any national and local regulations.
- Fixing: check/inspect all the fixing annually and re-tighten as necessary (see table 1).
- Windy conditions: fans should not operate in case of strong wind
places where it is frequently windy.
- Weight: it is recommended that the building structure is capable to bear approx. twice the weight of the
fan as well as a torque of at least 350Nm. A professional structural engineer should perform an evaluation
before purchasing the fan.
- Key safety features: make sure that all the supplied key safety features are used to install the fan to
provide a comprehensive protection of people, animals, equipment and property.

10.7 INSTALLATION

• D ecide on the position the fan is to be installed keeping in consideration the following:
- the minimum distance from the floor to the lowest point of the fan is 10ft (3.05m - H size in the dimension
drawing). As necessary a different length downrod can be supplied as accessory upon request;
- the minimum distance from the fan blade to the side wall of similar obstruction is indicated in the dimension
drawing (C size);
- if possible avoid mounting the fan directly below lights to prevent any strobe effect caused by the moving blades;
- in any installation where fire sprinklers are placed, fan should not interfere with their operation;
- fan should not be placed near to supply air outlet or exhausting inlets of other HVAC equipment which could
decrease the fan capacity and compromise the indoor air quality as well as the occupants' comfort:
- supply air outlet should deliver air away from the unit;
- exhaust fan inlets or other return air point which could create negative pressure should not be located within
1,5 times the fan diameter;
- when mounting the fan, mark the floor with a large crosshatched circle to alert people of the overhead fan
location.
