Faema can be hard to track down for manuals and such. I think I have an e-mail here somewhere - will look.
In the meantime, a google search reveals nothing - which you probably did too. Not hopeful.
All pump driven machines are the same at the heart; boiler, pump, brew group... work works for a gaggia or rancilio, technique wise, will work for any other machine. The proof will be in the quality of the shots - which are dependent on the temperature regulation of the brew water in the boiler and as it passes through the group.
