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. * Install refrigerant tubing so that it does not block service access to the front of the unit.

- Page 12 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.
- Page 13 Section 10. Air Filter (not factory-installed) * External filter or other means of filtration is required. Units should be sized for a maximum of 300 feet/min. air velocity or what is recommended for the type filter installed. Filter application and placement are critical to airflow, which may affect the heating and cooling system performance. Reduced airflow can shorten the life of the system’s major components, such as motor, limits, elements, heat relays, evaporator coil or compressor.
