The airflow performance data was developed using fan coils with 10 ---kW electric heaters (2 elements) in the 019 through 037 size units and 15 ---kW heaters (3
elements) in the 043through 061 size units. For fan coils with heaters of a different number of elements, the external available static at a given CFM from the
curve may be corrected by adding or subtracting available external static pressure as indicated above.
