The 8530 don't *nned* 3-phase to run. It's normally equipped with a

The machine Robert is thinking of is the 86x0 machine, which have 3-phase
motors in the fans.

ISTR there was a model that had 3-phase blower
motors. A three-phase
motor will not operate on single-phase. It *has* to have all three legs
to run.
We had an 8530 that needed 3-phase. I had to install the plug on the
panel for our AC because our machine-panel only had two legs (everything
we had was single-phase 120VAC except the TU78 - 220V). Our AC was
large enough that it had a 3-phase compressor.
