Give me a few minutes to see if I have a diagram
Do not have the wiring on the AC10 series. I have the AC13, but it has a black orange and purple on fan. I will continue to look. Meanwhile I am going to open to other experts who mave a diagram available .Please wait to leave rating until we know for sure.
I am almost 100 % sure we wil be right though as it is a straight cool unit. Black will go to one side of Contactor Load1, The red will go to other side of contactor (Load2) and orange will go to FAN side of capacitor. The Red can either connect directly to the contactor or go to COM on the capacitor as they are supplied from same post on contactor.
