  • Page 24: Airflow Performance

    5. 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 airflow. Table 5.

  • Page 25: Ductwork

    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. The air distribution system has the greatest effect on airflow.
