Canarm Octa-Lite 8LEC Series 7
2 IMPORTANT INFORMATION
2.1 Canarm Safety Components
Canarm 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 effect caused by
the moving blades.
When mounting a fan in an area where objects may be lifted or moved into the path of the fan,
Canarm recommends marking or painting hash lines on the oor to alert personnel of the above
movement of the fan.
The 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. This shielded system reduces the likelihood of broadcasting and
receiving electronic noise which can interfere with radio and other sensitive equipment. This 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 Octa-Lite 8LEC 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, 8LEC Series, 16 foot, 8-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 Safety Cable
A Canarm fan should never be run without proper installation of Safety Cables. These are supplied
with every fan. You must install safety cable for warranty to be in effect.
3.4 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.
3.5 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 Octa-Lite 8LEC Series 9
4PREPARING 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 qualied 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 specications 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 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.
CAUTION/ATTENTION
!

NOTE: Mounting to I-beams requires the purchase of the I-beam Adapter Kit in lieu of standard Upper
Yoke from Canarm.
5.8 Attach I-Beam Adapter (to I-Beam)
Measure the ange width of the I-beam you are wanting to hang the fan from. Compare the I-beam
ange width to the diagram below to determine what mounting holes you will require.
Secure the upper yoke to the I-beam with the “Clamping Plate” hardware shown below. Tighten the
bolts to 90 ft-lb, (122 N-m) using a 3/4” socket and torque wrench.
Proceed to “Hanging the Fan” on pg. 21.

b. (8) 1/2” Flat Washer
c. (4) 1/2”-13 Nylock Nut
d. (2) Clamping Plate
Install the “Clamping Shims” only if the thickness of the I-beam ange exceeds 3/8” (1cm). The
mounting holes of the shim are closer to one side than the other. Make sure this side is facing the I-beam.
Installez les cales de serrage que si l’épaisseur de la semelle de la poutre supérieure à 3/8 “(1 cm).
Les trous de xation de la cale sont plus près d’un côté que de l’autre. Assurez-vous que ce côté est

5 MOUNTING METHOD 4: PURLINS
NOTE: Purlin brackets and hardware are available from Canarm upon request and not included
standard.
5.9 Selecting Proper Angle Irons
Select the proper angle irons based on the requirements stated under section 5.3.
5.10 Pre-Drill Purlins
Drill four 9/16” (1.4 cm) diameter holes centered vertically along the purlin spaced apart 4.5” (11.4
cm) horizontally and 1.5” (3.8 cm) vertically. These holes should match up perfectly with those of the
purlin bracket and back plate.
5.11 Attach Brackets and Backing Plates
Purlin mounting brackets and backing plates should be attached using the provided 1/2” grade 5
bolts, washers, and nylock nuts. A washer should be placed on both sides of the plate for each bolt.
5.12 Pre-Drill Angle Iron Brackets Holes
Your angle iron should be cut to allow 1/2” (1.27 cm) clearance between the end of the angle iron
and the purlin you are mounting to. Drill one 9/16” (1.4 cm) diameter hole centered vertically exactly
1” (2.54 cm) from the edge on both ends of the vertical wall of the angle iron. Drill a second hole
exactly 3” (7.6 cm) inward from the rst hole on both ends. Repeat for the second angle iron. These
holes will be used to secure the angle iron to the purlin bracket with the provided hardware.
5.13 Pre-Drill Angle Iron Fan Mounting Holes
Measure the distance between the mounting points that each angle iron will span. Drill two 9/16” (1.4
cm) diameter holes centered on the bottom wall of each angle iron. The two holes should be spaced
5.5” (13.9 cm) apart to best match those of the upper yolk. These holes will attach the upper yolk to
the angle iron.
