Install the Fan
1.For best performance, choose a location with the shortest possible duct run and minimum number of elbows. Do not mount near cooking equipment, as shown in Fig. 1.
2.Attach adjustable mounting brackets to fan, but leave the screws loose until proper height is determined, shown in Fig. 2. Cut hole to dimensions shown in table below:
Do not install fan in this area

NOTE
3.Installation of ductwork
is critical to the performance of the fan, shown in Fig. 5. 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.
