AIR DELIVERY — CFM (With Filter)* AND POWER DRAW (WATTS)**
* Actual external static pressure (ESP) can be determined by using the fan laws (CFM
2
proportional to ESP); such as, a system with 1010 CFM
at 0.5 ESP would operate at cooling airflow of 800 CFM at 0.31 ESP and low-heating airflow of 515 CFM at 0.13 ESP. (See air delivery curves.)
† Low heat CFM when bypass humidifier switch (SW3) on control center is used. The listed low-heating wattage is with bypass humidifier switch
(SW3) OFF.
‡ Ductwork must be sized for high-heat CFM within the operational range of ESP.
** Wattage data provided is for the circulating blower with bottom only return-air supply and does not include draft inducer, accessories, or gas controls.
†† Refer to the air delivery curves for airflow CFM above this ESP
