INTRODUCTION TO OZONE
Ozone (O
3
) is generated by irradiating air or oxygen (O
2
) 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. Locate Model PZ2-1 or PZ2-2 Ozonators or the compressor unit for PZ2-4 and higher models so that dust, sand, debris,
chemicals, or other foreign objects are not sucked into the compressor's intake fan or hose (if equipped with Noise
Attenuator).
2. Check electrical system: 240VAC double switched per N.E.C. standards; 120VAC single switched.
3. Check for and correct all plumbing for leaks.
4. Check for Suction Line Check Valve. Equipment may draw if no check valve is present.
5. Balance the pH.
6. Backwash the filter.
7. Shock the pool with a non-lithium-based material. The use of Calcium Hypochlorite or Sodium Hypochlorite is
recommended.
NOTE: If the pool has a Diatomaceous Earth (DE) filter, a 3/4" ball valve must be installed between the pump and the input side of
the Venturi Injector.
INSTALLATION
NOTE:
The instructions in this document provide general installation guides. Consult your dealer for specific installation instructions.
Additional information is available at www.prozoneint.com. Check system for any visible shipping damage. If damage has occurred,
contact the delivery company and your dealer immediately. Before beginning installation, please turn to the Installation Kit Inventory
Section and verify that all listed parts are on hand.
