SAFETY

IMPORTANT SAFETY INSTRUCTIONS

READ AND FOLLOW ALL 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.
    1. Replace damaged cord immediately.
    2. Do not bury cord.
    3. Connect only to a properly grounded, grounding type receptacle.
  5. Install at least 5 feet from the inside wall of the tub or 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.
  6. A wire connector is provided on the unit to connect a minimum No. 8 AWG (8.4 mm2) solid copper conductor between this unit and any metal equipment, metal enclosures of electrical equipment, metal water pipes, or conduit within 5 feet (1.5 m) of the unit.
  7. Wear safety glasses when drilling and tapping holes for installation of unit.
  8. 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.
  9. Turn off power at source breaker before servicing the unit.
  10. SAVE THESE INSTRUCTIONS.

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 electrical system: 230VAC double switched per N.E.C. standards; 120VAC single switched.
  2. Check for and correct all leaks in plumbing.
  3. Check for Suction Line Check Valve. Equipment may draw if no check valve is present.
  4. Balance the pH.
  5. Backwash the filter.
  6. Shock the pool. The use of Calcium Hypochlorite (CaCl) is recommended.

NOTE: If the pool has a Diatomaceous Earth (DE) filter, a 3/4" ball valve (not furnished) must be installed on each end of the Venturi Bypass Line.

INSTALLATION

NOTE: The instructions in this document provide general installation guides. Consult your dealer for specific installation instructions. Additional information is available on Internet 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.

Tools Needed: Cordless Power Drill, 1/2 inch Drill Bits, Screw Driver, Adjustable Wrench, Pliers, Wall Mount Screw Anchors, Knife

PZVII SERIES WITH BYPASS VENTURI

  1. Directly after pump and before filter, attach one 1-1/2 inch or 2 inch brass saddle clamp using attached screws.
  2. After all existing equipment (including heater, chlorinator, etc), attach second 1-1/2 inch or 2 inch brass saddle clamp to return line using attached screws.
  3. Drill a 1/2 inch hole in the pipe through the hole in top of each saddle clamp.
  4. Apply Teflon tape to threaded end of each 3/4 inch x 3/4 inch fitting.
  5. Screw 3/4 inch x 3/4 inch fitting snugly in top of each saddle clamp.
  6. Cut a 6 inch (15cm) length (plus or minus 1 inch) of 3/4 inch hose and install it on the 3/4 inch barb on the saddle clamp next to pump and secure with a screw-type clamp.
  7. Insert venturi injector into 6 inch length of hose making sure flow is away from saddle, and secure with screw-type clamp. Flow is marked on side of injector with an arrow.
  8. Insert opposite end of venturi injector into remaining length of 3/4 inch hose and secure with a screw-type clamp.
  9. Attach loose end of 3/4 inch hose to the 3/4 inch barb on the second saddle clamp and secure with a screw-type clamp.
  10. Mount the PZVII ozone generator one foot above the maximum water level to prevent water from contacting electrical equipment. Be sure to mount system close enough for 6 feet of braided hose to reach injector.
  11. Attach one end of the 1/4 inch polybraided hose to the PZVII ozone generator and the other end to the barb on the venturi injector; secure with clamps.
  12. Electrical Installation: System is 120 or 230 VAC, 50/60 HZ. Wire Prozone ozone generator system to circulation pump switch or timer. Prozone system and circulation pump should be started simultaneously. Use N.E.C. or local code grounding and installation procedures for swimming pool equipment.

CAUTION: Make sure the voltage is the same as prescribed on the side of the Prozone ozone generator. Overvoltage will void customer warranty.

OPERATION

A. PROZONE PZVII 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. A 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. The system is installed on the return water line and operates during regular filtration cycles. It is operated automatically by wiring the Prozone system directly to the circulation pump. A check valve is employed to prevent water back up 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

  • 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.
