NOTES: 1. Airflow based upon dry coil at 230V with no electric heat and factory-approved filter. For FMA4X, airflow at 208V is approximately the same as 230V because the multi-tap ECM motor is a constant torque motor. The torque doesn't drop off at the speeds in which the motor operates. 2. Airflow is equivalent for front or bottom return configurations.
