SPECIFICATIONS
AIRFLOW PERFORMANCE* (CFM)
* With factory approved filter, 10-kw elec heat 001 and 002 sizes, 15-kw elec heat 003 and 004 sizes 230-volt.
AIRFLOW PERFORMANCE WITH ACCESSORY COIL (CFM)
NOTES:
1. Airflow based upon dry coil at 230v with factory approved accessory filter and electric heater (10-kw electric heat, sizes 001 and 002;
15-kw electric heat, sizes 003 and 004).
2. To avoid potential for condensate blowing out of drain pan prior to making drain trap:
—Return static pressure must be less than 0.4 in. wc
—Horizontal applications of 048-070 sizes must have supply static greater than 0.20 in. wc
Airflow outside max ARI airflow of 450 cfm/ton on 018-154 sizes
Airflow above 400 cfm/ton on 060-070 sizes. Airflows in this region could result in condensate blowing off coil or splashing out of drain pan.
