Looking for a wiring diagram for a Rivacold Blocksystem Condensing Unit / Evap system as fitted to Cold Rooms

The Model Number is:
FAM 016Z 001/C

I wrote to the Italian Manufacturer, who referred it to the UK agent, who called me, and who referred it back to Italy !!

Its been over a week now and I dont think Ill hear anything.

So if anyone can oblige, Ill be grateful.

Thank You
