Product review (1 stars): THEY CHANGED THE 240v PLUG.
If you owned the prior model and had a 240v outlet installed for it with 3 prongs, including two angled in a V-pattern, YOU CANNOT PLUG THIS IN.
You will need an electrician to install a new, different 4-prong 240v outlet.
Just look elsewhere.  I suspect there's a reason that no one stocks these any more.
