Which fan motor wires to connect?

I have a brand new AC condenser fan that I'd like to mount in my attic as an attic exhaust fan, but I can't interpret the wiring diagram on the side of the motor.

From the attached picture, can someone help me figure out which wires to connect to the black, white and ground wires of my home's standard 110v wiring?

Thanks in advance.

Do you have the capacitor for the motor?

I do have the capacitor. Do I need that to wire the fan motor?

I don't see where that motor is capable of running on 120 volts. Looks like just 208/230

Ah, okay, so maybe I can't connect it to 110v? Or can I somehow wire the 110v to the capacitor and then connect the capacitor to the fan motor?

The capacitor needs the same voltage as the rest of the motor. If this is for single phase residential that will be 240 volts. The capacitor is needed to start the motor.

Check with your HVAC contractor. Many have a bone yard of used but working units and parts. They may swap or give you a 120 volt motor. Just make sure you get a capacitor for the new motor. Used capacitors can work but it's one electronic component that seems to have a limited life span.
