Note that in general you can't necessarily take a 120V/208V three-phase
device that only uses two phases and wire it to a 240V circuit, because
it may designed for only 208V.  Similarly, you can't necessarily use a
240V appliance between two legs of 120V/208V three-phase.

However, in the case of the RP06 this should work fine, since Memorex
actually rated it for a voltage range that includes 208V and 240V.  I
don't recall the limits of the specified voltage range, and I don't have
the manual handy.
