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.

PREPARING FOR INSTALLATION

  1. Check for and correct all leaks in plumbing.
  2. Balance the pH.
  3. Backwash the filter on retrofit installation.
  4. Shock the pool. The use of Calcium Hypochlorite is recommended, or hydrogen peroxide if Baquacil is used.
  5. CAUTION:  Make sure voltage is the same as prescribed on the side of the Prozone Ozone Generator.

INSTALLATION       Tools Needed: Electric Drill with 7/8 hole saw (USE THIS SIZE ONLY), Screwdriver, Pliers, Box Knife

BYPASS INSTALLATION
(NOTE:  A Prozone saddle clamp or tee can be used on the outlet side of the filter for aboveground pools)  

1.       Place saddle clamp (201155) on the hard plumbing directly after the pump.  Place screws to hold saddle in place but DO NOT FULLY TIGHTEN.

2.       Drill a 7/8 in hole in the hard plumbing aligned through the saddle clamp outlet. 

3.       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 clamp screws.

4.       Place 1 in Polybraid Tubing (201828) over the 1-1/2 barb on the outlet side of the filter (remove existing hose if necessary).

5.       Place one end of the 1 in PVC Tee (201141) into the 1-1/2 in Polybraided Hose (201828) and the other end into the system tubing which was removed from the filter. Secure both ends of the 1 inch Hose (20264) with the large Metal Hose Clamps (200069).

6.       Connect one end of the in Clear Vinyl Hose (20264) to the outlet of the Injector (60002) and the other end to the in barb on the PVC Tee (201141).

7.       Secure both ends of the inch Clear Vinyl Hose (20264) with the small Metal Hose Clamps (20067).

8.       Cut a 5 inch length from the inch Polybraided Hose (20260).

9.       Connect the pieces of Polybraid Hose (20260) by inserting the Check Valve (20214) and securing with a Black Plastic Clamp (20185). Make sure you can blow air through the check valve towards the Injector Port.     

10.   Connect the short end of the Polybraid/Check Valve assembly to the open barb on the Injector (600002) with the Black Clamp (20185). 

11.   Connect the remaining end of the in Polybraid Hose to the in Barb on top of the ozonator and secure with a Black Clamp (20185). 

12.   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.

OPERATION

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 chemical usage.

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.

Sanitizers - A chlorine level of .5 ppm to 1 ppm is recommended
