Airflow performance data is based on cooling performance with a coil and no filter in place. Check the
performance table for appropriate unit size selection. External static pressure should stay within the
minimum and maximum limits shown in the table below in order to ensure proper cooling, heating ,
and electric heating operation.
[!] Required 3 5 0-450CFM/ton range.
[!] CFM means Standard Cubic Foot per Hour.
[!] Airflow based upon Air Handler Unit operates at 230V
with no electric heater kit and no filter. Airflow at 208V is
approximately the same as 230V.
[!] When there is an electric heater, please set the fan
speed based on the air volume that the electric
heater needs (not less than 350
C
FM/TON).
