ABSTRACT:
A switch over device provides a product dispenser with the capability to switch from a first diluent flow circuit to a second diluent flow circuit. The switch over device attaches to the dispenser, and includes a manifold having a first diluent inlet and a second diluent inlet in communication with a diluent outlet. The switch over device further includes a first and a second stem assembly, wherein the first and second stem assemblies are biased to a first position that interrupts flow from the first and second diluent inlets to the diluent outlet. In a second position, the stem assemblies permit fluid flow to the diluent outlet. The switch over device further includes actuators that enable an operator to easily switch from the one flow circuit to the other. The product dispenser may switch from virtually any type of diluent, and/or diluent temperatures, including ambient, chilled, and carbonated diluents.
