Question

I need help FAST. I have just installed a new A/C unit that calls for a 220V 20A. I ran 12/3 to the breaker box. The problem is with the outlet. I purchased an outlet from Home Depot which has three screws on the back. Obviousl one is for the ground leaving me with three wires left black, red and white. I called Home Depot and asked an employye fron the elec. dept. how to hook it up and he told me to put the white neutral on one srew and put both the black and red on the other. What concerns me is that he said he wasn't sure. I need an answer a.s.a.p. since it is extremely hot! Thanks.
