Data based on wet coil with entering air at 80 deg F DB / 67 deg F WB without air filter.
The maximum allowable pressure drop is 0.4 in H
2O.
The maximum CFM is the data at 0.4 in H
2O pressure.
Maximum airflow setting
Water blow-off could occur in certain installation positions if the airflow setting exceeds the maximum values listed.
NOTE
Airflow should not exceed the maximum airflow setting specified in Table 7-2. Exceeding these CFM limits may result
in water blowing from the coil surface and into the ductwork.
