Need help with connecting a four wire fan

[justme]

I am not a electrician and I need some help. I would imagine this should be an easy one for you guys. I am trying to hook up an indoor air filter that hangs from the ceiling. I cannot find a schematic for connecting to a power source. It is a four wire system. I am not sure if it is a one speed or two speed, although I would think it is a two speed. I just want the low speed hooded up. It has a white wire on one side of the capacitor and a brown wire on the other side that goes directly into the motor and the white wire goes out to be connected. It has a green wire for ground and that one is connected to the chassis. Then it has a black and a red wire tat also goes out to be connected. I had it running at my other house before I moved, so I know it's 120 volt. I need to know how I should hook this up to a (3) prong electrical cord. Notice that the orange and blue wire re not used Thanks!

Ok, I finally found the schematic. It is a 120 volt motor. Red= low speed, orange= medium low, blue= medium high, black= high. Black goes to line and white goes to line. Brown goes straight from the capacitor to the motor and white goes from the capacitor to the outside connection (line). It also has a green wire connected to the chassis that goes out for connecting. So, if I am understanding this right, I connect the white to the "neutral", I connect the black to the "hot" and I connect the green "chassis ground" to ground on the plug. What I am also not sure about is, if I want medium low instead of high can I just swap the black wire for the orange wire. Like I said, I only need one speed. Thanks!

Yes. Only connect one hot wire at a time. Wires for the other speeds will be live and need to be insulated from ground.

Glad you have it sorted. Feel free to post a photo of the nice looking radio chassis that is in the background!

This fan is to a filter for my house, I need it for my allergies. First time I hooked it up I got nothing. Instead of buying a new motor, I figured I would pull the motor and see if I could find the problem. When I got it on my workbench and plugged it in, it fired right up. So, now it have an excuse to rebuild my filter. The grommets are all shot, so it was probably rattling around quite a bit. I do remember it being pretty noisy. I need to make sure it's sealed tight also so it functions like it's supposed to. As far as old tube radios, I probably have several hundred. I bought a bunch from my friend when he shut down his shop. Lucien, Thank you for your assistance!
