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.
