Your going to have to fine tune it some. I have the Prizm 300g Deluxe. The water valve is generally turned to 1/4 on, the water will not come out running really fast at that rate, but it will. Turn the air valve up all the way, then down until you just hear the pump grumbling that its to much air, and your set. You want dry foam in the collection cup, not water. Your water level will be just below the collection intake portion, or just starting at the bottom of the large hole to the top of the cup. The bubbles will accumulate there, and will continue to collect, and push the dried foam up and out of the cylinder.
