Discrepancies with instructions

Im at the point in the setup to prime the water system. When trying to prime the high pressure both online and printed instructions say to click on HP Value, well on my unit where that should be it says Clutch. I have no idea if this is the same thing and before i make a wrong assumption on such a expensive piece of equipment i would like to know for sure. Of course their support is all closed on the weekends, if youre sending out a $10k piece of equipment you might want to make sure the instructions match.
