FIBERGLASS FAN
BELT DRIVE FAN
Belt drive fans are equipped with an automatic belt tensioner and v-belt. The rotary tensioner will compensate for any wear or stretching of
the belt. No adjustments are necessary. Belt will however wear after extensive use. Fan performance will be sacrificed if worn belt is used.
Listen for belt "squeeling" on startup. This would indicate that the belt requires changing or tightening.
The tensioner provides adequate tension when the alignment marks are between 2 and 3. (See Figure 4.) To adjust tensioner, loosen the 3/8"
bolt at the back of tensioner. Using a 15/16" wrench on the front hex, torque the tensioner clockwise until the alignment mark is at 3. Hold the
tensioner at this setting while you tighten the 3/8" bolt to secure the tensioner in this position. Check drive alignment using a straight edge to
make sure the belt is centered on the idler. If pulleys are not properly aligned, belts will wear prematurely.
Lubrication: Belt drive fans are provided with bearing blocks that are pre-lubricated & sealed. They have a double contact seal and steel
slinger that prevents most contamination. However, since the bearings are to operate in very damp and dirty conditions, re-lubrication is
recommended. The grease fitting of the unit should be carefully cleaned before use and the grease should be introduced slowly. Under
normal conditions, the bearings only need re-lubrication every 3 years. Nonetheless, we recommend that each bearing receive one pump
from a grease gun (or until fresh grease is pushed out), every time the unit is washed down (especially if detergent is used.)
NOTE: Use NLGl2 lithium base grease to ensure compatibility with original grease.
CAUTION: Do not use pneumatic grease guns. Slowly introduce grease with manual gun otherwise bearing seals will be destroyed.

ACCESSORIES
Canarm provides a full line of controls from simple on/off thermostats to sophisticated multiple staging controllers and PC based controllers.
Winter covers are available for colder climates where the fan is shut down for the winter. Performance enhancing cones are available for
24" to 50" sizes. These can improve performance and efficiency by approximately 5% for FG50, 7% for FG36 fans, and 9% for FG24 fans.
