INTRODUCTION TO OZONE
Ozone (O3) is generated by irradiating air or oxygen (O2) with ultraviolet radiation. Ozone is a molecule of oxygen that is formed when three atoms of oxygen are bound together instead of the normal two atoms. The extra oxygen atom makes ozone the most powerful oxidizer and sanitizer readily available.
Since ozone is unstable and quickly decomposes to normal oxygen under normal conditions, it cannot be shipped or stored. Therefore, it must be manufactured on site for immediate use. In normal air it lasts about an hour. In normal pool water it lasts just long enough to purify the water - less than 1 second.
Although ozone is mainly thought of as a sanitizer, it acts primarily as an oxidizer in the pool environment. In a typical pool run on 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 result 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.
- Check for and correct
all leaks in plumbing.
- Balance the pH.
- Backwash the filter on

of Calcium Hypochlorite is recommended, or hydrogen peroxide if Baquacil is

Place saddle clamp (201155) on the hard plumbing directly after the
pump. Place screws to hold saddle in place but DO NOT FULLY TIGHTEN.
Drill a 7/8 in hole in the hard plumbing aligned through the saddle clamp
Place the short end of the injector (600002) in the hole on top of the
saddle clamp, pushing injector in as far as it will go, then tighten saddle
Place 1 ½ in Polybraid Tubing (201828) over the 1-1/2 barb on the outlet
side of the filter (remove existing hose if necessary).
Place one end of the 1 ½ in PVC Tee (201141) into the 1-1/2 in

Metal Hose Clamps (20067).
Cut a 5 inch length from the ¼ inch Polybraided Hose (20260).
Connect the pieces of Polybraid Hose (20260) by inserting the Check Valve

Connect the short end of the Polybraid/Check Valve assembly to the open
barb on the Injector (600002) with the Black Clamp (20185).
Connect the remaining end of the ¼ in Polybraid Hose to the ¼ in Barb on
top of the ozonator and secure with a Black Clamp (20185).
Install Ozone Generator on base of pump pack using the metal screws
(20085) and washers (20085). Plug the Prozone Ozone Generator system to the
circulation pump switch or timer. The Prozone system and the circulation pump
should be started simultaneously. Use N.E.C. or local code grounding and
installation procedures for swimming pool equipment.
A. PROZONE PZ4 OZONE GENERATOR OPERATION
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 (vacuum) that
draws the ozone into the venturi mixing the bubbles as the water returns to the
pool. It is operated automatically by plugging 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
Although ozone is mainly thought of as a
sanitizer, it also 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 in conjunction with any
halogen, it oxidizes a large portion of the contaminants (usually referred to as
bather load) which result in the formation of combined chlorine. The result is
that more free chlorine residual is available and less chlorine is required to
maintain the pool. Ozone also provides 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.
B. WATER CHEMISTRY
- pH -
7.2 to 7.6. Ozone is pH neutral and will not
cause the pH value of the water to fluctuate.
- Total Alkalinity -
Total alkalinity is an important factor in water chemistry. Any level outside
the ideal range can cause the pH reading to bounce or to be inaccurate.
Therefore, the TA should be adjusted into the ideal range before any pH
readings are made.
chlorine level of .5 ppm to 1 ppm is recommended
