i know people that aren't plumbers and can install an electric water heater such as ew10 or ew15 no problems, so the fact that you are asking, i would give this advice.
put in a good price too do the job and then hire a qualified plumber to do the job and try to cream something off it.
as if you continue down this path even if it is under 15 litres someone could get killed, if install incorrectly, BE SAFE NOT STUPID.

So without MI what would be your method?
i have an expansion vessel, I'm sure I need a non-return valve...
what I'm asking is how should this look when I'm finished?
I appreciate all the feed back

Here is a link to the MI's in pdf format.

So now you have them. Can you confirm what model/ capacity of Europrisma it is your fitting or take a picture where the whole of the appliance can be seen IE the top? Did it come supplied with a separate Pressure release valve?

there is a 30 litre version that looks the same.
