SAFETY

READ AND FOLLOW ALL INSTRUCTIONS.

IMPORTANT SAFETY INSTRUCTIONS

  1. All applicable electrical codes must be followed during and after installation. All connections to be made by a qualified electrician.
  2. Disconnect all power at the main circuit breaker before installing the PROZONE unit.
  3. WARNING - To reduce the risk of injury, do not permit children to use this product unless they are closely supervised at all times.
  4. DANGER - Risk of electric shock.
  5. Replace damaged cord immediately.
  6. Do not bury cord.
  7. Connect only to a properly grounded, grounding type receptacle.
  8. Install at least 5 feet from the inside wall of the pool using non-metallic plumbing. The ozone generator is to be located one foot above the maximum water level to prevent water from contacting electrical equipment. Install to provide drainage of compartment for electrical components.
  9. A pressure wire connector is provided in the control box inside the unit to permit connection of a minimum No. 8 AWG (8.4 mm2) solid copper bonding conductor between this point and any metal equipment, metal enclosures of electrical equipment, metal water pipe, or conduit within 5 feet (1.5 m) of the unit as needed to comply with local requirements.
  10. Wear safety glasses when drilling and tapping holes for installation of unit.
  11. WARNING: Short term inhalation of high concentrations of ozone and long term inhalation of low concentrations of ozone can cause serious harmful physiological effects. Do not inhale ozone gas produced by this device.
  12. Turn off power at source breaker before servicing the unit.
  13. SAVE THESE INSTRUCTIONS.

TABLE OF CONTENTS


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. 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.

OPERATION

A. PROZONE PZ2 SERIES OZONE GENERATOR OPERATION

The Prozone system works when air is drawn across a high-energy vacuum ultraviolet (VUV) lamp, converting some air to ozone. The ozone is introduced into the water either by direct injection or through a bypass venturi system. For direct injection, the venturi injector is inserted directly into the return line of the pool creating a suction (vacuum) that draws the ozone into the venturi as the water returns to the pool. The bypass venturi system takes water directly after the circulation pump (highest pressure point), bypasses part of the water flow past filters, heater, etc. through a venturi injector, through contact tubing and then returns the water back to the pool return line. A check valve is employed to prevent water backup in the event of system failure. The system should be run 6-8 hours per day for best effect. Run time may vary depending on usage.

B. WATER CHEMISTRY

Water chemistry must be maintained to assure proper performance of the Prozone ozonator system and existing pool or spa equipment. The following levels are recommended:

  • pH - 7.2 to 7.6. Ozone is pH neutral and will not cause the pH value of the water to fluctuate.
  • Sanitizers - A chlorine level of .5 ppm to 1 ppm is recommended.
  • Shock - Non-lithiuum-based material such as Calcium Hypochlorite or Sodium Hypochlorite, etc.

The use of other chemicals is not usually required and they could cloud the pool water.
