In order to reset the pressure to 160psi at 1000cc/min. You need to adjust the set screw (on the pumphead) with an allen key (1/16") as follows:
Wind in the screw (clockwise) until you hear a click. Then re-wind (counter-clockwise) 1 complete turn. This sets the system pressure to 160psi.

Future HFS-6 delivery will have a supplimentary insert in the user manual, instructing the above. Apologise for the noticing this earlier due to some mis-communication between Aquatec and us.

Can this click be replicated? I was turning mine too fast and I'm not sure at what point I heard the 'click'. I estimated, but I'd like to go slower and get it exact if it is possible.
