7.0 AIRFLOW PERFORMANCE
Airflow performance data is based on cooling performance with a coil and no filter in place. Use this perfor-
mance table for appropriate unit size, external static applied to unit and allow operation within the minimum
and maximum limits shown in table below for both cooling and electric heat operation.
