Side Discharge
Make sure discharge is oriented in the same direction
as originally ordered, performance will change with
different discharge positions. Refer to Figure 8 for
proper side discharge definition and the Side Discharge
chart for dimensions. Consult factory for performance
corrections.
Duct Length
The inlet and outlet duct length should be approximately
two to three wheel diameters long before and after the
fan to achieve cataloged performance.
