2 Important Information
2.1 Canarm Safety Components
Tri-Lite fans are designed with redundant safety features to provide protection in the unlikely event of a
catastrophic failure. Follow installation instructions carefully when installing fans.
2.2 Fan Spacing’s and Placement
A standard ceiling fan should be mounted so that the bottom of the fans hub is 33 inches below the bottom of
the beam which it is mounted. Fan blades should be mounted between 10’ and 50’ above the oor with optimum
height between 20’-30’. If desired, extension bars are available to lower the fan if needed. Avoid mounting fans
directly below lights or skylights to avoid a strobe eect caused by the moving blades.
When mounting a fan in an area where objects may be lied or moved into the path of the fan, Tri-Lite Fans
recommends marking or painting hash lines on the oor to alert personnel of the above movement of the fan.
e area within 15% of the diameter when the fan is at rest is considered “close clearance”. It is extremely
dangerous to mount the fans within “close clearance” of any object or path of object. We strongly recommend
not mounting the fan closer than 15% of its diameter to any object or its path. If this is an issue, mounting
extension bars and smaller fans are available from Canarm.
2.3 Fire Suppression Systems and Fan Placement
If installing Fans in a location where re sprinklers are in place, do not interfere with their correct operation.
Fans should be located in the center of each sprinkler quadrant and no less than 3 feet below the sprinkler.
Review all codes applicable to sprinkler systems prior to installation; it is the customer’s responsibility to see that
the installation is completed to code and that it is correct.
2.4 Shielded Motor Cable
To minimize electromagnetic interference and stray voltage, Canarm recommends the use of shielded input
voltage cable. is shielded system reduces the likelihood of broadcasting and receiving electronic noise which
can interfere with radio and other sensitive equipment. is shielded motor cable and the controller cable must
be run in separate conduit at least 6 inches apart. Electrical interference and stray voltages are the liability of the
installer and are not covered by Canarm under warranty.
2.5 Check Compliance with Federal, State, and Local Codes
Check all relevant codes to make sure product certications, product listings, and building regulations are met.
Code compliance is the responsibility of the installer.

8 Canarm Tri-Lite 3LEC Series
3 mOUNTING cONSIDERATIONS
3.1 General Mounting
Each type of mounting system requires a specic mounting bracket. Most are available from Canarm. Check
with the contractor, building owner, or architect to ensure the structure is sound and will support the weight
of the fan before beginning installation. Canarm provides guidelines for mounting fans; however, it is the sole
responsibility of the building owner and installer to ensure the safety of the mounting system, that the building
structure is sound, and the installation complies with all federal, state, and local codes.
3.2 Weight
A Standard 1.35-horsepower, Tri-Lite 3LEC Series 16 foot 3-blade fan and mounting assembly weighs about 250
pounds. In inverted-blade applications designed to blow air upward, there is an additional downward force of
about 80 pounds due to fan thrust. We recommend applying a safety factor of 2 times the stated hanging weight
of the fan when determining the capabilities of the building structure.
3.3 Torque
e maximum torque that must be handed by the mounting system and the building structure will occur at
the fans startup. For a 16 foot fan, maximum potential startup torque is 300 -lbs. Tri-Lite fans use a so-start
technology which allows the rpm to ramp up as desired over 60 seconds. e event of this max torque being
applied is unlikely and will only apply due to a failure of the variable frequency drive and its so start technology.
3.4 Safety Cable
A Tri-Lite fan should never be run without proper installation of Safety Cables. ese are supplied with every
fan. You must install safety cable for warranty to be in eect.
3.5 Guy Wires
While in operation a fan can sway due to minor imbalance or because of wind. Since the mounting system is
capable of swiveling, it will not stop fan movement, so it is important that the guy wires be installed properly.
Proper installation includes the angle and tension of the guy wires. See page 22-23 for more information.
3.6 Universal Mounting Hardware
We recommend mounting the fan to a horizontal structural beam, however, this is not always possible in
buildings with pitched roof construction. For this reason, our universal mounting system is designed to allow the
fan to hang in a level position perpendicular to the ground by rotating the upper yoke 90 degrees.
When cutting or drilling into a wall or ceiling, take care not to damage electrical wiring or other utilities.
Lorsque vous coupez ou percez un mur ou un plafond, prenez garde à ne pas endommager les ls électriques ou
d’autres services publics.
Select a location that is free from obstructions that may interfere with the fan’s operation.
Choisissez un emplacement qui est libre de tout obstacle pouvant interférer avec le fonctionnement du ventilateur.
CAUTION /ATTENTION
!

Canarm Tri-Lite 3LEC Series 9
4 Preparing the Work Site
4.1 Mechanical Installation
A 24’ (7.3m) Tri-Lite 3LEC fan (our largest model) weighs, at maximum, 310 lbs (140kg). A scissor li, or other
suitable means for liing and a minimum of two installation personnel, will be required.
Tri-Lite Fans can be hung from an I-beam, angle irons, or unistrut. 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.
e 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.
e spacing between multiple fans should be no less than 2.5x the fans diameter when measured from the center
of the fans.
e 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 -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 qualied electrician. Incorrect assembly
can cause electric shock or damage the motor and controller.
e installation of a Tri-Lite 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 specications on page 31 for appropriate circuit requirements.
Each fan requires dedicated branch circuit protection.
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
oor.
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.

Support Directly From Building Structure.
All mounting instructions assume that the building structure from which the fan will be hung is
of sound construction, undamaged, and capable of supporting loads of up to 650 lbs (295 kg). It
is the sole responsibility of the customer to verify that the building’s structure is adequate for fan
installation. Canarm recommends consulting with a structural engineer prior to fan installation.
Aider directement à la structure du bâtiment.
Toutes les instructions de montage supposent que la structure du bâtiment à partir de laquelle le ventilateur sera
