Notes
1 - Switc h blue a nd r ed wir es for 208V oper ation.
2 - The blk/wh and gray/wh wires are removed when Aux He at is installed
3 - Refer to units X13 MOTOR LOW VOLTAGE CONNECTION table for factory settings.
4 - Wires p rovided for Auxiliary Heat low voltage control. When connected the Auxiliary Heat
powers blower and controls. Wires are secured at blower.
5 - Field installed SPST relay required for dual fuel instal lation.
