--- Shaded boxes represent airflow outside the required 300-450 cfm/ton.
NOTES: Airflow based upon cooling coil at 230V with no electric heat and no filter. Airflow at 208V is approximately the same as 230V
because the mult-tap ECM motor is a constant torque motor. The torque doesn’t drop off at the speeds in which the motor operates.
