- 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 18 thru 36, 3 element heater sizes 42 thru 60). Airflow at 208 volts is
approximately 10% lower for models 018, 024,030, 036, 042, 048 and 060. For models 019, 025, 031, 037, 043, 049 and 061, 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 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 042 - 060 sizes must have supply static greater than 0.20 in wc.
3.Airflow above 400 cfm/ton on 048-060 size could result in condensate blowing off coil or splashing out of drain pan.
