- Shading - 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 019 through 037, 3 element heater sizes 043 through 061).
2.Airflow at 208 volts is approximately the same as 230 volts because the multi-tap ECM 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.
