Tuff finding info on this, appear to be 3 speed. Can you get the control? At the end of the model number it says "6.3uF" which usually means 6.3 micro farads(The Value of the Capacitor)The capacitor(if it does use one) needs to be rated for the voltage or higher.
Just a wild guess, and wouldn't try yet, could be something like blue and brown to capacitor, white to neutral, and red, orange and black for the speeds? It really bites that some common information is not more easily available.
