Thanks for the reply. I've found a drawing inside the front cover plate and the requirement is for a 240v supply but with a centre tap, (120v), to provide a neutral. This will be possible with a 1 to 1, 240v/240v centre tap transformer. The loading of the drier is 4.5kw so a big transformer is required.
The main problem is that the m/c is designed to run 60hz so would run 15 to 20 percent slower on 50hz and take more current, not good for the long term.
The guy has shipped two of these over from the States . Ooops.
