STANDARD EXHAUST FANS
READ INSTRUCTIONS COMPLETELY BEFORE INSTALLATION & SAVE THEM FOR
REFERENCE
Congratulations on the purchase of your quality-built direct drive, wall
exhaust ventilation fan. All of these models use totally enclosed motors with
thermal overload protection. Variable speed motors are high-efficiency motors
that save on electrical costs and can be run as a single-speed motor. The
motors are mounted on heavy gauge welded steel rod motor mounts that have a
Bright Zinc finish. Fans come fully assembled and 100% of fans are tested for
proper operation before shipping.
THESE ARE GENERAL INSTRUCTIONS THAT COVER OUR SINGLE, VARIABLE, AND TWO-
SPEED STANDARD FANS, AS WELL AS OUR SINGLE-SPEED EXPLOSION-PROOF MODELS..
STANDARD FANS
These models have a rugged, welded steel box housing with a powder-coated
finish and aluminum or plastic exhaust louvers that are supported by long-life
nylon bushings. The louvers open automatically when the fan starts up and
close when the fan stops
EXPLOSION-PROOF FANS
Explosion-proof fans are equipped with single-speed explosion-proof motors and aluminum blades so sparks cannot occur if a metal object obstructs the blade path. Explosion proof fans have the same quality welded steel box housing and heavy gauge welded guard as the standard fans. These fans should be used to ventilate hazardous areas. Locations are considered hazardous if the atmosphere contains or may contain gas, vapor, or dust in explosive quantities.
THE MOTOR AMBIENT TEMPERATURE IS NOT TO EXCEED +40˚C OR -25˚C UNLESS THE MOTOR NAMEPLATE SPECIFICALLY PERMITS ANOTHER VALUE. THE FOLLOWING TABLE INDICATES WHICH HAZARDOUS CLASSIFICATIONS CANARM EXPLOSION PROOF FANS DO AND DO NOT MEET.
Canarm explosion proof fans DO meet the following hazardous classifications.
CLASS 1, DIVISION 1 (GASES, VAPORS)
GROUP C Acetaldehyde, cyclopropane, diethlether, Ethylene, isoprene
GROUP D Acetone, acrylonitrile, ammonia, benzene, butane, ethylene dichloride, gasoline, hexane, methane, methanol, naphtha, propane, propylene styrene, toluene, vinyl, acetate, vinyl chloride, xylene
CLASS 2, DIVISION 1 (COMBUSTIBLE DUSTS)
GROUP F Carbon black, coke or coal dust
GROUP G Flour, starch or graindust
| Canarm explosion proof fans DO NOT meet the following hazardous classifications.
CLASS 1, DIVISION 1 (GASES, VAPORS)
GROUP A Acetylene
GROUP B Butadiene, ethylene oxide, hydrogen, propylene oxide
CLASS 2, DIVISION 1 (COMBUSTIBLE DUSTS)
GROUP E Aluminum, magnesium and other metal dusts with similar characteristics
THE MOTOR AMBIENT TEMPERATURE IS NOT TO EXCEED +40˚C OR -25˚C UNLESS THE MOTOR NAMEPLATE SPECIFICALLY PERMITS ANOTHER VALUE. THE FOLLOWING TABLE INDICATES WHICH HAZARDOUS CLASSIFICATIONS CAN ARM EXPLOSION-PROOF FANS DO AND DO NOT MEET.
INSTALLATION
Installation is fast and simple. A sturdy framed wall opening should be prepared in advance to the size indicated for your fan in the charts above. With lag bolts for wooden frames or nut, bolt and lock washers for steel frames, secure the fan using the four mounting holes provided, one in each corner of the fan.
ELECTRICAL CONNECTIONS
WARNING: BE SURE POWER IS OFF AT THE ELECTRICAL PANEL BEFORE WIRING.
WARNING: ALL ELECTRICAL WORK SHOULD BE PERFORMED BY A QUALIFIED ELECTRICIAN.
These fans are supplied with single, two or variable speed motors. Single and
two speed motors are 120V only. Variable speed motors are dual voltage. All
dual voltage motors are pre-wired at 240V in our factory. Rewire motor as per
motor nameplate if running fan at 120V. Please see the motor nameplate for
wiring diagram. Make electrical connections in motor connection box as per the
motor nameplate. Follow Chart #1 for wire sizes. Two speed fans require a two
speed control or 3 position toggle switch to change from high/ low/off. See
wiring diagram with control for 2 speed wiring instructions.

NOTE:
• NEC Article 310-5 – *Minimum conductor size for general wiring at 115-440VAC is number 14AWG.
• Above wire sizes based on approximate 5% voltage drop during starting: copper conductors: and 75°C type THHW, THW, THWN, RH, RHW insulation etc. For aluminum wire, increase two wire size steps minimum. See NEC Article 310 for ampacities of aluminum conductors.
• Type S, SO, SJ, SJO, etc. flexible cable wire sizes. See NEC article 400 for ampacity.
OPERATION
MOTOR COOLING AND TO PREVENT MOTOR FAILURE.
All fans are direct drive. Fans with variable speed motors can be operated as
an energy-efficient single-speed fan or in variable operation with the proper
controller. As mentioned above two speed fans require a two-speed control or 3
position toggle switch to change from high speed to low and off.
WARNING: GUARDING SHOULD BE USED IF FANS ARE MOUNTED LOWER THAN SEVEN FEET (2
METRES) OFF FLOOR OR GROUND LEVEL.
ACCESSORIES
Canarm provides a complete line of manual and thermostatic controls. Canarm also offers wall mount exhaust shutter kits, replacement shutter sets, and weather protection hoods.
MAINTENANCE
MOTORS ARE EQUIPPED WITH AUTOMATIC OVERLOAD PROTECTION AND MAY RESTART WITHOUT
WARNING. ALWAYS
DISCONNECT FROM POWER BEFORE ATTEMPTING SERVICE. Motor, blade, and louvers
should be kept clean of any buildup to prevent premature motor failure and to
achieve proper performance. Automatic louvers should be kept operating freely.
As with all mechanical equipment scheduled inspections should include checking
that all hardware is secure and blade set screws are tight.
