  • Page 16: Ductwork

    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.

    7.0 REFRIGERANT CONNECTIONS Keep the coil connections sealed until refrigerant connections are made. See the Installation Instructions for the outdoor unit for details on line sizing, tubing installa- tion, and charging information. Coil is shipped with “No charge”. Evacuate the system before charging with refriger- ant.
