Hi young Alan,
Nice to see the heating nearly installed. As for instructions, in 1971 I installed one of the first Sauna Units in a hotel in Ayr. I say installed, it was like wiring a power station My major problem being errrr ALL the instructions were in Finnish There were loads of wiring diagrams but in those days they had a different colour codeing compared to here. My boss at the time, had to send the instructions to a linguist in Edinburgh to put the instructions into English.
Soooo what I am trying to say is, well done getting it all connected, and your still talking to Dave!
Iain.
