Having purchased a second hand Truma S3220, the unit was shipped to me in three boxes! The core heater, the front bezel/panel and a rear panel. I cannot fathom out how to put it all back together again and fit it into my caravan which prior to my purchasing it, must have had a Truma S3002 fitted. I will presume it was taken out and discarded at some time as faulty. Anyone able to help or where I can find an "exploded" view of the full unit please.

I had abit of a trawl around as I have the S3002 in my motorhome but didn't find anything worthwhile.

Try www.Truma.com when in select your country flag [stated as this is a world forum]
they MIGHT help.
or if in UK www.trumauk.com I can see S series but not your model but you might get some results.
