Shaded boxes represent airflow outside the required 300-400 cfm/ton.

• When JMM5A0B24MM21SA uses the 18 KBTU outdoor unit, select SCFM between 450 and 675.

NOTES:

1.         Airflow based upon dry coil at 230V with no electric heat, no filter. For 24, 30, and 36 sizes, 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.

2.         Airflow is equivalent for front or bottom return configurations.

3.         SCFM is nearly the same with cooling performance airflow, the gap is in the 1 to 2%.
