HotSpring Spa Freshwater III Ozone Generator - HotSpring/Tiger River. This 2010 FreshWater® III CD Ozone Generator effortlessly replaces the older FreshWater II High Output ozonator taking up half the space while packing twice the punch. Our corona discharge method of ozone generation will crank out a higher concentration (PPM) of ozone and that concentration level won't decrease over the years like the ultraviolet style ozonators. Easy to install, the new Freshwater III CD Ozonator's bubbles will give your spa water that "rain fresh" fragrance. Installs in any 1995-2010 Hot Spring or Tiger River spa model. Installation time is about 45 minutes.
Note: If you have a pre 1997 Hot Spring or Tiger River, the ozonators were most often hard wired into the circulating pumps power cord.
