Setting Airflow

With all ductwork connected and a clean filter in place, measure the
External Static Pressure (ESP) of the unit in locations below. Use the
appropriate airflow table for the furnace and outdoor unit installed.

Measurements must be made prior to the evaporator coil, if equipped,
and after the filter.
