Belt tensioning can be adjusted by changing the position of the fan motor(s) by rotating the motor base adjustment
screw, which extends through the bottom frame angle.
Check belt tension as follows:
1. Shut off fan(s).
2. Rotate the fan sheave half a turn to evenly distribute the tension in the belt before measuring.
3. Check belt tension by verifying both following conditions.
- The deflection amounts 10 mm / m free belt length (see figure below).
- The deflection force required is between the minimum and maximum values given in the table below.
CAUTION
Fan has to be blocked while replacing belts.
