Does your manual actually use the words "2
phase"?
Indeed it does.

Last paragraph on page 42.
220v is not 2 phase, although, I can't tell you
exactly why. It's been
told to me, that each 110v hot wire of 220v(actually 120v and 240v in
the US) is really the same phase, but inverses of each other, or
something like that. Real 2PH, was used quite a bit in Pennsylvania,
but has been mostly phased out, if not entirely.
You know, I'm just not sure. I can't quite decide. Sometimes it appears as
it 'Two Phase' is a misnomer, as you suggest - but if the units
configuration can apparently be configured for Three-phase just as easily
as 220v "Two phase"... it would seem to me that... oh, heck, I don't
understand enough about this to be sure!
I do recall someone saying that they'd run a 220v unit on a stove outlet,
so I guess US 220v single-phase is what they must run on.
I guess what I'm trying to work out is whether all you do is pop out one
of the OLS' and it'll "just work"... somehow I seriously doubt it, but
there isn't that much electrical wiring in the unit EXCEPT for the OLS' -
so what would you reconfigure?
Alas SGI's techpubs only contain the User Guide and are thin on all other
manuals for the Onyx, that I can find at any rate.
Many thanks to all;
