I'm opening a small town coffee house in Nebraska and bought a Rancilio Z11/AT machine as my starter machine. Not sure if I did the right thing, but it seems to have a few baristas in the area very excited. I've had some difficulty understanding the plumbing of this machine. It has what looks like an inlet and an outlet right next to each, there's an up-arrow next to the left inlet and a down-arrow next to the outlet. I've got this hooked up from my water filtration to the inlet and i have the outlet dropped into a floor sink at this time. Is this the way this machine is intended to be hooked up? I've attached a pic to show what I'm looking at.
I'm also experiencing only 6 bars of pressure and am thinking that I need to add a pump to the system. I need some advise as to what pump would go best with this system to maintain 9 bars?
Last question. Can I use a blind basket to clean this type of machine? I've noticed that the user manual only shows using a blind basket with the Omnicron model and doesn't show this option with the AT model. Am I just reading this wrong?
Any help/advise is appreciated.
