INSTALLATION
1. Secure the unit through the mounting holes located on the angle iron frame.
2. Rotate the blower wheel by hand. It should not rub against the inlet venturi. If rubbing occurs, loosen the hub
bolts and adjust the motor wheel position.
3. Install the motor mounting platform using the hardware supplied with the optional 10-30 HP motor platform.
Mount the motor to the motor platform (motor platform shown in Figure 2) from Delhi Industries, or base mount
the motor. (supplied by others)

4. Mount the blower sheave on the blower shaft and tighten its set-screw securely on the key of the shaft. (See
Table 1 for drive data).
5. Mount the motor sheave 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.
6. When using the 10-30 HP motor platform, with the slide base in its minimum position install the V belt within the
sheave grooves. Adjust the sheave on the blower shaft to ensure proper pulley alignment (see Figure 3) and
secure in place. A straight edge across the face of the driven pulley should be parallel to the belt once proper
alignment has been achieved.

7. Adjust the slide base motor platform to tighten the belt. Ideal belt tension is the lowest tension at which the belt
will not slip during start up. As rule of thumb suggests that ¾” of deflection mid span under medium finger
pressure (2-3 lbs.) for every foot of span is approximately proper belt tension. Tighten all hardware once belt
has been adjusted properly.
