Hello Damian,

I have the same setup. Feel free to ask any questions. I would recommend two things:
First remove the screws from the cover of the processor and leave them away. You can then easily remove the cover anytime for filling the tanks and removing the racks for cleaning.
The first time you use it, fill all tanks with water in order to check if the system is leaking. It is a heavy mess, if developper or fixer starts running out. Leaks are sometimes caused by loose hoses after transport.

When you insert a paper into the processor, the display goes off. It turns back on when the paper leaves the insert. This is the signal that the system is ready to take the next piece of paper. This is controlled by a magnetic switch. If it does not work, the cover is not in the right position.

Good luck!
