Redsy:
We have wired quite a few of this type unit, and I have not seen any with cords/factory wiring as you explained.
Sanyo and Carrier are the brands out here.
Sealtite and EMT between the Cu and the fan/coil units. (4 wires)

BTW; anyone have any input as to a disco required/needed at the interior unit???
(Fan.Coil)
