INLINE DUCT BLOWERS
MOTOR, PULLEYS & BELTS (See Table below)
1. Mount the blower pulley on the blower shaft and tighten the set screw securely on the key of the shaft.
2. Mount the motor pulley on the motor shaft. Leave some clearance between the pulley and the motor end bell. Tighten the set screws
on the key of the motor shaft.
3. Install the motor on the motor platform using the hardware provided.
4. With the platform in its minimum position, install the V-belt within the pulley grooves. Position the motor on the motor platform to
ensure proper pulley alignment (see Fig. 2) and secure to the motor platform. (A straight edge across the face of the driven pulley
should be parallel to the belt once proper alignment has been achieved).
Note: Adjustments in the variable speed pulley require pulley re-alignment.
5. Pivot the motor platform to tension the V-belt and lock in place using the 2 bolts on both sides of the blower. (Ideal belt tension is the
lowest tension at which the belt will not slip during start up. A rule of thumb suggests that 3/4" of deflection mid-span under medium
finger pressure (2-3 lbs.) for every foot of span is appropriate.)
WARNING
EXCESSIVE BELT TENSION IS THE MOST FREQUENT CAUSE OF BEARING WEAR AND RESULTING NOISE.
PROPER BELT TENSION IS CRITICAL FOR QUIET EFFICIENT OPERATION.
Ideal belt tension is the lowest value under which belt slip will not occur at peak load conditions.
