OPERATION
WARNING: VARIABLE SPEED FANS SHOULD HAVE THE MINIMUM SPEED SET TO OPEN LOUVERS AT LEAST ONE INCH FOR PROPER
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.
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.
ACCESSORIES
Canarm provides a complete line of manual and thermostatic controls. Canarm also offers wall mount exhaust shutter kits, replacement shutter

WARNING: GUARDING SHOULD BE USED IF FANS ARE MOUNTED LOWER THAN
SEVEN FEET (2 METRES) OFF FLOOR OR GROUND LEVEL.
