Electricity connection to Kohler K-1733 steam generator
I am struggling to interpret the connection for the Kohler K-1733 steam generator.
The scheme is supposedly provided here: http://www.us.kohler.com/onlinecatal.../1060226_2.pdf (see page 12).
What is not clear to me is whether I shall join together the L1 and L2 black wires and connect them both to 240V Live, and connect Neutral to green wire. Or whether I shall connect green to Ground, L1 to Neutral and L2 to 240V.
Internaly green wire is connected the body of the unit, which seems a little strange if I have to connect it to Neutral (I would assume Ground for the Body).
The black (L1 and L2) wires are connected to big HOMER XMCK-502240CP contactor, which is not connected to the body in any way.
I live in Europe, where we have only 240V mains.
I am puzzled by references to 120V in the said scheme and do not want to ruin the unit running 240V into 120V circuits.
Thanks for your help.
