Installation Recommendations
Install the Fan - Continued
3.Installation of ductwork is critical to the performance of the fan, shown in Fig. 11. Straight ductwork (1) or ductwork that turns in the same direction as the wheel (2) is recommended. Ductwork turning opposite the wheel direction (3) will cause turbulence and back pressure resulting in poor performance.
4.Slide ductwork over the fan’s discharge collar and securely attach it with sheet metal screws. Make sure the screws do not interfere with damper operation. Check damper to make sure it opens freely.
