The goal of a perfect inductor cycle is to drain the product and the rinse water without ever "sucking air." Maintaining a specific water level at the end of the drain is vital for two reasons:
This is the most critical mechanical reason. If the inductor drains too low, a large "gulp" of air enters the suction line. When this air pocket reaches your centrifugal carrier pump, it can cause the pump to airlock.
The Result: The pump loses prime and stops moving fluid completely.
The Fix: You often have to stop the engine, bleed the air out of the pump housing, and re-prime—wasting valuable time in the middle of a fill.
Any time air is introduced into the hose going to your sprayer tank, the possibility of foaming greatly increases. By keeping a solid "plug" of liquid in the line, you ensure the mix remains stable and the sprayer tank doesn't overflow with foam.
This setting is configured using a dedicated wizard found in the Manual Mode tab.
