Maintenance

2.Visually inspect the entire unit casing for chips or corrosion. Remove rust or corrosion and repaint surfaces.

3.Clean fan wheels and fan shaft. Remove any rust from the fan shaft with an emery cloth and recoat with L.P.S. 3 or equivalent.

4.Inspect the drainpan for sludge or other foreign material. Clear the drain openings and drain line to ensure adequate flow.

5.Rotate the fan wheel and check for obstructions in the fan housing. The wheel should not rub on the fan housing or cutoff. Adjust to center if necessary and tighten the wheel set screws per the torque recommendations in Table 31, p. 64.

6.Examine flex connector for cracks or leaks.

7.Repair or replace any damaged duct material.
