Notes
1 - Switch blue and red wires for 208V operation.
2 - The blk/wh and gray/wh wires are removed when Aux Heat is installed
3 - Use manufacturer's part number 19P592-01 (jumper bar assembly)
when single source power is required.
4 - When installed, the Auxiliary Heat powers blower and controls.
5 – Low voltage wiring CLASS 2.
6 - Wires provided for Auxiliary Heat low voltage control. Wires are secured at blower.
7 – Ground wire only on units with aluminum air coils.
