INTRODUCTION TO OZONE
The Prozone system produces ozone when air is drawn across a special high-energy vacuum ultraviolet (VUV) lamp, converting some air to
ozone. A venturi injector is inserted on the return line, by-passing water back into the return line of the pool which creates suction that draws
the ozone into the venturi, mixing the bubbles as the water returns to the pool. It is operated automatically by connecting the Prozone system
directly to the circulation pump or plugging into a timer. A check valve is employed to prevent water back up in the event of system failure. A
siphon loop is recommended for added backpressure resistance. The system should run 8-12 hours per day for good results; 24 hours per day
for optimum water clarity and minimum chemical usage.
Although ozone is mainly thought of as a sanitizer, it acts primarily as an oxidizer in the pool environment. In a typical pool, using chlorine only,
up to 90 percent of the chlorine may be used up in reactions unrelated to disinfection. The byproducts of these reactions are combined chlorines.
Combined chlorines are the cause of eye irritation, odor, and the other unpleasant side effects of chlorination. When ozone is used, it oxidizes a
large portion of the contaminants (usually referred to as bather load) which results in the formation of combined chlorines. The result is that more
chlorine is available for disinfection and less chlorine is required to maintain the pool. Ozone also provides some disinfection, but an ozone
residual cannot be established, so the use of chlorine or bromine is always recommended. Baquacil may also be used in conjunction with the
Prozone system for water sanitation. Refer to the Baquacil manual for shocking instructions.
PREPARING FOR INSTALLATION

5.
Check for and correct all leaks in plumbing.
Balance the pH.
Backwash the filter on retrofit installation.
Shock the pool. The use of Calcium Hypochlorite is recommended, or hydrogen peroxide if Baquacil is used.
CAUTION: Make sure voltage is the same as prescribed on the side of the Prozone Ozone Generator.
The Table below summarizes the levels that are recommended by The Association of Pool and Spa Professionals
(APSP). It is important to maintain these levels in order to prevent corrosion or scaling and to ensure maximum enjoyment
of the pool. Test your water periodically. Take a water sample in to be professionally tested by a Pool and Spa
Professional at least once a month. See our web site for more information on Basic Pool Water Chemistry.
