Airflow based upon dry coil at 230v with factory approved filter and electric heater (2 element heater sizes 18 through 36, 3 element heatersizes 42 through 60).2. Airflow at 208 volts is approximately the same as 230 volts because the X13 motor is a constant torque motor. The torque doesn’t drop off atthe 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.5.
