Installation
7. Use the adjusting bolts on the motor support to adjust belt tension. A
correctly tensioned belt does not slip when the fan is running—and the
“tight” side is straight between sheaves. The “slack” side will have a
slight bow. If possible, use a commercially available tension measuring
device.
Avoid over-tensioning.
Too much tension reduces bearing
and belt life. Check the tension on new belts after 8 to 12 hours of
operation.
8. Install the belt guard as shown in
Figure 2
.
9. Install fan cylinder splice plate and fan guard.
10. Check bearing housing oil cup level. Fill to the proper level with SAE
0 (ISO 100) weight oil.
