Notes:
1.Airflow based upon dry coil at 230V with factory-approved filter and electric heater (2 element heater sizes 024 through 036, 3 element heater sizes 048 through 061). For FZ4A models,
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.
2.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 048 - 061 sizes must have supply static greater than 0.20 in. wc.
3.Airflow above 400 cfm/ton on 048-061 size could result in condensate blowing off coil or splashing out of drain pan.
