NOTES:
1. Airflow based upon dry coil at 230v with factory approved filter and electric heater (2 element heater sizes 1800 through 3600, 3 element heater sizes 4200
through 6000).
2. Airflow at 208 volts is approximately the same as 230 volts because the 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 4200 − 6000 sizes must have supply static greater than 0.20 in. wc.
4. Airflow above 400 cfm/ton on 4800 − 6000 size could result in condensate blowing off coil or splashing out of drain pan.
5. Not recommended for use above 0.60 inches water column external static pressure.
6. Shading − Airflow outside 450 cfm/ton.

When taking a static reading across a WET coil, adjust the static pressure numbers by adding the values in this table (for a given CFM, wet coil will
have greater static pressure drop than dry coil).
