NOTES:

1. Capacities shown are gross and do not account for fan motor heat. To determine net capacities, fan motor heat must be subtracted from the gross MBh. To calculate supply fan motor heat use the following equation:

Fan motor heat (MBh) = 2.8 x fan motor brake horsepower.

2. To determine capacities at other than cfm shown, refer to the capacity correction factors in table.

3. The blank spaces indicate operating points which are outside of the recommended operating range of the unit.
