Service: How do I winterize my Mixmate?

Winterizing your Mixmate is the most important maintenance task of the year. Because the system utilizes precision gear meters and electronic valves, any trapped water that freezes can cause expensive housing cracks and internal damage.


Phase 1: Gravity Drain

Start by opening all low points in the system to allow gravity to do the bulk of the work.

  • Inductor Low Points:

    • Open the main Drain Valve.

    • Disconnect the Rinse Line connection.

  • General System Low Points:

    • Drain all Pumps.

    • Disconnect Tote connections and Carrier Line connections.

    • Open and drain all Fill Lines and Discharge Lines.


Phase 2: Cycle and Position Valves

Water often gets trapped inside the "ball" of a valve even when it appears empty.

  1. Cycle Valves: Open and close every valve multiple times to move trapped liquid out of the internal cavities.

  2. Storage Position: After cycling, leave all Ball Valves in the CLOSED POSITION.

    Why? Leaving a ball valve closed provides the most internal volume for expansion if a small amount of residual moisture remains and freezes.


Phase 3: Clear the "P-Traps" and Meters

Some components act like a "P-trap" and will not drain by gravity alone. You must use compressed air or RV Antifreeze (non-toxic) to clear them.

  • Jug and Tank Rinses: The rinse lines on inductors naturally hold water. Force air or antifreeze through these lines until you see it exiting the nozzles.

  • Gear Meters: The tight tolerances of the gears hold liquid effectively. You must force air or antifreeze through the meters.


Phase 4: Tablet and Electronics

  • Storage: Remove the tablet from the bracket and store it in a climate-controlled environment. Extreme cold can damage the screen and degrade the battery.

  • Power: Disconnect the main power source or ensure the battery is maintained to prevent the "Voltage Drop" issues discussed in the troubleshooting section upon spring startup.
