Page 12: Airflow Performance Data
Installation Manual 5.0 AIRFLOW PERFORMANCE Airflow performance data is based on cooling performance with a coil and no filter in place. Selecting the appropriate unit size performance table for external static applied to the unit allows operation within the minimum and maximum limits shown in the table below for both cooling and electric heat operations. - Page 13 Installation Manual The air distribution system has the greatest effect on airflow. The duct system is totally controlled by the contractor. For this reason, the contractor should use only industry-recognized procedures. Heat pump systems require a specified airflow. Each ton of cooling requires between 350 and 450 cubic feet of air per minute (CFM), or 400 CFM nominally.
