Assembly

1.Visually inspect all tapped blade mounting holes for any debris which could cause problems when tightening cap screws.

2.Install blades with rotation arrow on top side and pointing in a clockwise direction.

3.Hold each blade level and tighten the six cap screws just enough to hold the blade level.

4.Do not torque cap screws. Blades must be free to turn in retaining ring to adjust pitch.

The trial pitch angle is the calculated setting for design conditions

Note(water rate, heat load, air density, and brake horsepower). The trial

5.Select a position on the fan circumference and rotate each blade to this common location when setting or checking blade pitch. All blades must be pitched with the blade axis pointing in the same direction. Support the blade tip to maintain the proper plane of rotation while setting the fan pitch.

6.Set the pitch angle and torque cap screws for each blade. Set the pitch angle using a straight edge and bevel protractor 2" (51mm) from blade tip as illustrated. Blades should be within ±1⁄4° of the desired pitch.After the de- sired pitch is obtained progressively tighten blade cap screws to 30-35 ft·lbƒ (41-47 N·m) torque. A crowfoot wrench may be necessary to torque cap screws that cannot be reached with a socket.

7.Install hub cover using cap screws and resilient washers.

8.Tighten cap screws between 10 and 15 ft·lbƒ (14-20 N·m) torque.

Maintenance

Preventative maintenance will prolong useful life and assure continued trouble-free operation. After the first week of operation and subsequently at six month intervals:

1.Visually inspect the fan for airborne debris damage and corrosive at- tack.

2.Torque blade cap screws.

3.Remove any accumulated scale or dirt.

4. Clear blade drain holes.
