This shows the tank selector valves. The operator can chose either
the front or rear tank to pump chemical from.
The air valve provides a way to blow the chemical from the lines. By
removing the quick connect from the mixer and putting the hose in a
container. You can save almost the entire chemical in the lines.
After blowing out the lines you can open the rinse tank valve and run
the pump to clean the pump and lines.
