The airflow performance data was developed using fan coils with 10---kW electric heaters (2 elements) in the 018 through 036 size units and
15--- kW heaters (3 elements) in the 042 through 061 size units. For fan coils with heaters of a different number of elements, the external avail-
able static at a given CFM from the curve may be corrected by adding or subtracting available external static pressure as ind icated ab ove.
