We analyze absorption troughs from two outflows within PKS J0352-0711 from spectra taken with HST/COS, which cover the diagnostic-rich 585-900 Angstrom rest-frame wavelength range. The higher velocity outflow (-3160 km/s) shows absorption troughs from high ionization potential (IP) ions including Na_IX, Ca_VII-VIII and Ar_VIII as well as from low IP ions such as O_III-V, Ca_IV-VI, and S_IV-V. There are also hints of more exotic ions of K_IX, Cl_V, and Cl_VII. The lower velocity outflow (-1960 km/s) similarly has absorption troughs from both high IP ions (Mg_X and Ne_VIII) and low IP ions (O_IV-V and N_IV). Each outflow requires at least a two-phase photoionization solution. From column density ratios including O_IV*/O_IV and O_V*(J=2)/O_V*(J=0), of which observing O_V* is a first, we determine the electron number density, distance, energetics, and potential for AGN feedback of each outflow.
