SIDE DISCHARGE OPTION
The side discharge option provides several advantages, from
removing a system effect problem, increasing performance,
or even reducing installation labor. The most notable is
reducing system effects. In Fig. 1, notice how the air, when
discharged into the corner, will take several duct lengths
before becoming smooth again. This is not the case with
a side discharge. Notice now in Fig. 2 as air comes into
the fan/corner and leaves the fan/corner, you have nice
smooth airflow providing a more predictable system. Duct
length prior to or following the installation location should
be approximately two to three wheel diameters to achieve
cataloged performance.
DISCHARGE CONFIGURATION
Make sure discharge is oriented in the same direction as
originally ordered, as performance will change with different
discharge positions. Right side discharge will give you 108%
of cataloged performance and the left side will give you
109% of cataloged performance. Refer to Fig. 3 to locate
an orientation that fits your application and Fig. 4 and 5 for
proper side discharge definition. Consult your local rep for
performance modifications.
