Under normal operating conditions, the product lines between your totes and valves remain primed with chemical. However, when switching to a different crop or preparing for winter storage, you must perform a standardized clean-out to remove all chemical residues.
Note: The only lines that should not be rinsed during a standard daily mix are the product lines between the totes and the product valves/singles. Use the following procedure only for deep cleaning.
The process for cleaning a product line is the same whether you are using a valve stack or a standalone "single."
Switch to Clean Water: Disconnect the product end of the hose from the tote and connect it to a clean supply of water (or a dedicated rinse tank).
Enter Manual Mode: Navigate to Manual Mode on your Mixmate tablet.
Activate the Input: Tap the associated Card for the product input you wish to clean. This will open the valves and activate the flowmeter reading on your screen.
Engage the Pump: Start your main carrier pump to begin pulling clean water through the product hose and into the system.
The "Pulse" Technique: Cycle the input ON and OFF multiple times while the water is flowing.
Why? Cycling the valve forces water into the cavities of the ball valve housing, clearing out trapped chemicals that a steady stream might miss.
Complete the Flush: Once you have pulled a sufficient volume of clean water through (and the sight glass or meter shows clear), turn off the pump and close the input on the tablet.
Product Integrity: Prevents "hot" loads caused by leftover chemical from a previous crop.
Valve Longevity: Prevents sticky residues from hardening inside the valve balls, which can eventually lead to seized actuators or torn seals.
