Wiring and Pressing Sequence

The following diagrams show the electrical and plumbing connections. Note that since October, we switched to a single, 2-valve subplate, as opposed to 2 single subplates. This addresses back pressure issues, as subplates are rated for 2000 PSI back pressure from downstream valves.

The document also shows the full sequence of pressing steps under automatic operation.
