  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. 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.
  6. Wear safety glasses when drilling and tapping holes for installation of unit.
  7. 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.
  8. Turn off power at source breaker before servicing the unit.


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 ozygen 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.


  1. Check electrical system: timer set properly; 240VAC double switched per N.E.C. standards; 120VAC single switched
  2. Check all plumbing for leaks.
  3. Check the filters: clean or replace.
  4. Add non-lithium-based shock. The use of Calcium Hypochlorite or Sodium Hypochlorite is recommended.
  5. For best results, drain water and fill with fresh water. It is easier to clean unused water, though the ozonator will still remove substantial impurities from fresh tap water!
  6. Start all equipment and check pressure of the filter.


NOTE: The instructions in this document provide general installation guides. Consult your dealer for specific installation instructions. Additional information is available at 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, 1-1/8 Inch Hole Saw, Screw Driver, Adjustable Wrench, Pliers, Wall Mount Screw Anchors, Knife




The PZ5 ozone generator may be mounted in any orientation. It may be fixed to a wall using wall mount screws through the inside floor of the case. Metal case units can be mounted using flexible straps to isolate vibrations. Place the unit above water level or loop the ozone delivery hose above water level. This will prevent water from siphoning down into the ozonator.

  1. Cut a 6 inch length of the 1/4 inch hose.
  2. Attach one end of the 6 inch length of hose to the 1/4 inch barb on the Prozone ozone generator and secure with a clamp.
  3. Attach the other end of the 6 inch length of hose to barb on the inlet side of the check valve and secure with a clamp. Make sure flow is toward the spa.
  4. Attach one end of the remaining length of 1/4 inch hose to the other barb (outlet side) on the check valve and secure with a clamp.
  5. Route the hose so that at some point it passes above the water level. You may need to tie the hose up to keep it in place.
  6. For temporary or simple installations, the Optional MP-2 Mycropore TM diffuser may be inserted into the other end of this hose, secured with a clamp, and the diffuser merely hung over the side.
  7. For a permanent and better looking installation, a 1-1/8 inch hole may be cut in the side near the bottom of the spa or container to accept the MP-3 diffuser.
  8. NOTE: This, of course, necessitates draining the spa or conatainer. Hole should be cut from inside
  9. Electrical: System is 120 VAC, 60Hz; 240 VAC, 50/60 Hz or 12 VAC/DC.. 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 spa equipment.

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



The Prozone system produces ozone when air is drawn across a special high-energy vacuum ultraviolet (VUV) lamp, converting some air to ozone. Ozone is introduced into the water through a porous metal disk (diffuser) which creates extremely fine bubbles. As the bubbles rise, the ozone is absorbed into the water where it reacts. In the case of spa applications, the ozone is introduced via the "ozone-ready" air venturi inherent in virtually all spas manufactured today. For spas and other water containers not ozone-ready, or for temporary or simple installations, a diffuser may be inserted into the ozone generator output hose, and the diffuser merely hung over the side.


  • 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-lithium-based material such as Calcium Hypochlorite or Sodium Hypochlorite , etc.
  • The use of other chemicals is not usually required and they could cloud the spa water.
