For minimum design airflow, see airflow performance table for each unit.

To calculate temp rise at different air flow, use following formula:

Temp. Rise across Elect. Htr =	kWx3414
	1.08xCFM

Notes:

1.The minimum allowable airflow for a 3 ton with a 17.4 KW heater is 1020 CFM.

2.The minimum allowable airflow for a 4 ton with a 17.4 or 17.6 KW heater is 1440 CFM.

3.The minimum allowable airflow for a 5 ton with a 23.0 KW heater is 1900 CFM.
