Page 10: Installation In An Unconditioned Space
3.4 INSTALLATION IN AN UNCONDITIONED SPACE IMPORTANT: There are two pairs of coil rails in the air handler for default and counter flow application. If the air handler is installed in an unconditioned space, the two unused coil rails should be removed to minimize air handler surface sweating. The coil rails can be easily removed by taking off the 6 mounting screws from both sides of the cabinet. -
Page 11: Power Wiring
4.2 CONTROL WIRING IMPORTANT: Class 2 low voltage control wiring should not be run in conduit with main power wiring and must be separated from power wiring, unless class 1 wire of proper voltage rating is used. • Low voltage control wiring should be 18 Awg. color-coded. For lengths longer than 100 ft., 16 Awg. -

Select performance table for appropriate unit size external static applied to unit allows opera- tion within the minimum and maximum limits shown in table below for both cooling and electric heat operation. -
Page 13: 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”.
