I tried to find it, but didn't have the patience.  There is a photograph of the condenser label, but I could not read it.  I looked at my Prius (2005 model) but the condenser is under the car and I did not crawl under there to look.  Pretty tight fit.  I have to put it on blocks to change the oil.  Next time, I'll look, but that will be a while.
