Airflow outside 450 cfm/ton.
---
NOTES:
1. Airflow based upon dry coil at 230v with factory- -approved filter and electric heater (2 element heater sizes 018 through 037, 3 element
heater sizes 043 through 061).
2. Airflow at 208 volts is approximately the same as 230 volts because the X- -13 motor is a constant torque motor. The torque doesn't drop
off at the speeds the motor operates.
3. To avoid potential for condensate blowing out of drain pan prior to making drain trap:
Return static pressure must be less than 0.40 in wc.
Horizontal applications of 043 - - 061 sizes must have supply static greater than 0.20 in wc.
4. Airflow above 400 cfm/ton on 049- -061 size could result in condensate blowing off coil or splashing out of drain pan.
