PREPARING THE WORK SITE
4.1 Mechanical Installation
A 24’ (7.3m) 8LEC fan (our largest model) weighs, at maximum, 310 lbs (140kg). A scissor lift, or other
suitable means for lifting and a minimum of two installation personnel, will be required.
Canarm fans can be hung from a unistrut, angle irons, or an I-beam. See installation instructions on
the following page. Do not mount the fan to single purlins, trusses, or bar joists. Consult a structural
engineer for installation methods not covered in the manual.
The fan installation area and path must be free of obstructions such as lights, cables, sprinklers, or
other building structure. We strongly recommend not mounting the fan closer than 15% of its diameter
to any object or its path.
Do not install the fan where it will be continuously subjected to high winds (ex. Under a high velocity
HVAC system). Allow a required 2x the fans diameter between the fan and the HVAC (or other air-
moving) equipment when measured from the center of the fan to the equipment.
The spacing between multiple fans should be no less than 2.5x the fans diameter when measured
from the center of the fans.
The mounting structure must be able to withstand the torque which is generated by the fan. A 20’
diameter fan generates a maximum of nearly 300 ft-lb (406.7 N-m) of torque during operation.
4.2 Electrical Installation
To reduce the risk of electrical shock, wiring should be performed by a qualified electrician. Incorrect
assembly can cause electric shock or damage the motor and controller.
The installation of a Canarm fan must comply with the National Electrical Code, ANSI/NFPA 70-1999,
and all local codes.
All unused conductors that share conduit with the AC supply feeds must be grounded on both ends.
If required, a local disconnect should be installed per NEC and all local codes.
Refer to specifications on page 31 for appropriate circuit requirements.
Each fan requires dedicated branch circuit protection.
(I-Beam Adapter Kit Required)
To reduce the risk of injury to persons, install the fan so that the blade(s) is at least 10 feet (3.05 meters)
above the floor.
Pour réduire le risque de blessures, installez le ventilateur de sorte que la lame (s) est d’au moins 10
pieds (3,05 mètres) au-dessus du sol.
