If adding an ozonator to an ozone-ready spa requiring an in-line injector, you'll first need to install this injector. Our 3/4" Ozone Injector
Kit is the best choice. This quality Venturi has 3/4" water connections and standard 1/4" barbed fitting for ozonator supply hose. A section of spa flex hose is easily snipped out for installation of an Ozone Injector. The injector creates a suction which pulls ozone from the ozonator,
mixes it with water, and delivers it to a jet in the spa. Our kit
includes adjustable clamps for a water-tight seal.
After installing injector, ozonator output line is connected to the injector suction bib fitting. To prevent water from backing-up into the ozonator, a check valve should be installed. The ozonator output line should be looped high in the spa cabinet (above water level). This
is called a Hartford Loop, and provides additional protection from water back
flow.
