Airflow Performance
Airflow performance data is based on cooling performance with a coil and no filter in place. Check the
Performance table for appropriate unit size selection. External static pressure should stay within the minimum
and maximum limits shown in the table below in order to ensure proper.

Shaded boxes represent airflow outside the required 300-450cfm/ton.
NOTES:
Airflow based upon cooling performance at 230V with no electric heat and no filter. 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.
G2 signal occupies Tap (1) reserved for Ecoer thermostat (EST01) to get even better dehumidification control in cooling.
