Wellington, i wouldn't use the tunze wavebox on the profilux. I am more than happy to help you. Here is the instruction
1. Make sure the wavebox has a straight path
2. Make sure your return nozzle not pointing at it or the same direction next to the wavebox direction Ahem... Diego
Dialing
Turn the white knob on your controller counter Clockwise (CW) till stop.
Slowly (i mean super slow) adjust the white knob on your controller CW. Take 1 min to observe between adjustment.
Keep on turning the knob and observe till you get the right wave pattern.
If you want to find your max, keep on turning the knob a little bit at the time and observe 2 things will happen
1. the wave will get bigger
2. The wave disappear
If the wave get bigger, keep turn the knob till the wave disappear. One the wave disappear, just turn the knob counter CW to where you were. You should get the wave back and that is your max

. If you need any more help, you are more than welcome to drop me a call....
