So I got the big blower fan for a DIY laminar flow hood but I can't figure out how to wire it. It's from a furnace and has four wires coming off the motor, a red, a white, an orange, and a blue. I've tried a few combinations wiring it to a power cord and plugging it into an outlet but haven't gotten it to work. Here's a picture of the label.
Any suggestions?
