I think it’s what they call the “easy start” option.
My pressure pro came with it also.
I do not understand how it works…
Pretty sure it allows water to cycle through like a mini bypass. But I’m not 100%

I will suggest to open the ignition box and expose the plug with the fuse and close it back up. Makes for an easy fuse replacement when your machine doesn’t want to start.

How does it not cycle water all the time?
Nice looking unit and trailer!
Easy start has a valve that closes when a certain pressure or flow is reached.
