How can I connect a 9013G pressure switch to control a 3-phase motor with only a 2-pole set of contacts?

Product Line:
9013 pumptrol pressure switch 
Wire 2 legs of the 3 phase motor through the 2 poles of the pressure switch. Breaking 2 phases will start and stop the motor. Wire the third leg direct. Install a disconnect upstream of the pressure switch.
