a. For
Furnace
Units—Connect wiring from the EAC terminals to
a unit disconnect switch in the attic, and then connect the wiring
from the disconnect to the electrical box on the unit, using a
proper UL rated fitting at the electrical box knockout on the unit.
Follow standard wiring configuration: Black = high voltage;
White = neutral; Green = ground.
b. For
Fan Coil
Units—Connect wiring from the transformer using
the quick connect kit to the unit disconnect switch in the attic,
and then connect the wiring from the disconnect to the electrical
box on the unit, using a proper UL rated fitting at the electrical
box knockout on the unit. Follow standard wiring configuration:
Black = high voltage; White = neutral; Green = ground.
