10‑ Measure the final fan diameter. By using a different hole in the blade retention sleeves the fan diameter can be altered for the ap- propriate fit within the cylinder. 1⁄2" minimum clearance between all blade tips and the fan cylinder is recommended.

Fan Installation Instructions

1—Be sure motor is locked out.

2—Clean the hub bore and driving shaft extension for the full length of the key.

3—Insert the key in the keyway. The top of the key must be below the top of the shaft by not more than 1⁄8" (3 mm) . The key is a tight fit across the width and must never be altered.

4—After cleaning, apply a coat of anti-seize compound to the en- gagement portion of the shaft.

5—Raise the fan assembly above the shaft and slowly lower the hub onto the shaft with the keyways aligned. Make certain the key does not slide down during installation.

6—Install the Hub Retention Cap Screw with Lock Washer. Torque hub retention cap screw to 40 ft·lbƒ (54 N·m).
