You will be presented with a brown, a blue and a black along with the green/yellow ground. Which wires get "disconnected"?
You will get no guidance from the installation instructions since they don't call for a disconnect.
Would adding one be a 110.3(B) violation?
All of this wiring is way past where the line cord enters the machine (in the outside unit)
A hint on the top question. If you hooked this up with 14-3 wg Romex without reidentifying the white it would be a 200.6 violation
As a side note, do you require a disconnect for ceiling fans?
