I read the manual some more. 9 amps is just the name plate rating. Looks like it normally uses around 6 amps at 240v like I originally thought. They put 9 amps on the name plate but that is only for 208V systems, as in 2 legs of 120v 3 phase. Other wise that would be one heck of a brown out.
I found a partial roll of 12/3 SJ so that is what I will be using.
Oh and I'm wiring 10/3 triplex (yes 2 hots, neutral and ground, 4 wires total) to run from the main breaker box the outside A/C box so I can plug in a welder or plasma cutter to that circuit.
