What Is Ozone? • Ozone is “active oxygen”, nature’s special element. Each ozone molecule consists of three oxygen atoms. • Ozone is a natural purifier. • Ozone has a clean, fresh scent often noticed after a rainstorm. • It occurs naturally in the Earth’s upper atmosphere from the sun’s UV rays, and in the lower atmosphere during a thunder/lightning storm. a p S • Life safely exists because of the protection of the ozone layer. n ia l a r • There is a small amount of ozone in the air we breathe.
• BOTTLED WATER HAS BEEN PURIFIED WITH OZONE SINCE 1982. • OZONE IS USED IN RESIDENTIAL POOLS AND SPAS TO GREATLY REDUCE CHLORINE AND BROMINE USAGE. ADDITIONALLY, OZONE CREATES AN AQUATIC ENVIRONMENT THAT IS EASIER TO MAINTAIN THAN WHEN JUST USING TRADITIONAL CHEMICALS. Ozone Is Healthy and Safe Ozone Is Healthy: a p S • Ozone leaves no chemical by-products in water - it converts into life-giving oxygen. • Ozone leaves no chemical taste or smell.
Ozone is Convenient for Pools and Spas • Ozone does not have to be purchased or stored. Ozone is generated on-site and is introduced into the water automatically. • Ozone does not affect the pH balance of water, thus minimizing pH adjustments. • Ozone helps reduce total dissolved solids in water. a p S • Ozone eliminates much of the routine maintenance because it does such an effective job of keeping the water clean.
Does Ozone Work? Ozone is a Powerful Oxidizer • Ozone is the most powerful oxidizer and disinfectant that can safely be used in pools and spas. • Ozone is the alternative water purifier to traditional chemicals such as chlorine and bromine: ozone kills bacteria 3,000+ times faster! • CHLORINE PRODUCES MANY BY-PRODUCTS, INCLUDING CHLORAMINE, THAT ARE TOXINS IN THE WATER THAT SMELL BAD AND CAUSE IRRITATION TO HUMANS. OZONE ELIMINATES CHLORAMINES.
Ozone Production Technologies Ultraviolet (UV) Light - light energy This is how ozone is produced in the upper atmosphere via the sun’s UV rays. UV Ozone Generators: • Utilize a UV lamp to produce ozone • Typically for low concentration/low output applications n ia l a r a p S st u A This is how ozone is produced in the lower atmosphere via lightning. u rts a . aGenerators: mCD Ozone P o c . Corona Discharge (CD) - electrical energy a sp s t r pa www.delozone.
Ultraviolet Ozone Production “Energy Field of Light” Low Intensity Ozone Production A special UV lamp gives off a specific frequency (185nm) instantly converting oxygen (O2) molecules into ozone (O3-active oxygen molecules) inside the generator. n s Au au arts . om P a sp ia l a r a p S t c . s rt a p All “DELZONE” ozone generators for residential pools and spas use UV lamps and ballasts to generate ozone.
Corona Discharge Ozone Production “Energy Field of Electrons” High Intensity Ozone Production In the case of our Eclipse line of CD ozone generators, ambient air (oxygen) passes through an air gap between a high voltage electrode and a stainless steel grounding electrode. The “energy field of electrons” created by the high voltage electrode instantly converts oxygen (O2) molecules into ozone (O3). n s Au au arts . om P ia l a r a p S t c .
How Ozone is Made (Corona Discharge Example) Oxygen molecules (O2) are split by high voltage electrodes resulting in two individual oxygen atoms (O1). n s Au au arts . om P Oxygen atoms (O1) unite with other oxygen molecules (O2) to produce Ozone (O3). a sp ia l a r a p S t c . s rt a p Hence: (O1) + (O2) = (O3) www.delozone.
How Ozone Works • Ozone is an unstable compound generated by the exposure of oxygen molecules to a high energy electrical discharge. • The weak bond holding ozone’s third oxygen atom is what causes the molecule to be unstable and thus, very effective. n s Au au arts . om P a sp ia l a r a p S t c . s rt a p www.delozone.
How Ozone Works (continued) • An oxidation reaction occurs upon any collision between an ozone molecule and a molecule of an oxidizable substance (i.e. bacteria, fungi (mold & yeast), viruses, forms of iron & manganese…) • The weak bond splits off leaving oxygen as a by-product. • During an oxidation reaction, organic molecules are changed and dissolved metals are made no longer soluble. n s Au au arts . om P a sp ia l a r a p S t c . s rt a p www.delozone.
UV versus CD Ozone Technology Comparison • Most UV generators produce ozone concentrations that top out at 550 ppm. The CD technology used in the ECLIPSE line of residential pool & spa ozonators produces up to 2,500 ppm (over 4 times more ozone than UV) - Higher ozone concentrations promote increased dissolution of ozone into the water. - Higher ozone concentrations provide cleaner and clearer water while further reducing chlorine use.
ECLIPSE Products DEL Ozone offers a full product line of Eclipse Corona Discharge ozonators for use in spas or pools. Our newest spa unit, the Eclipse Platinum, offers up to 65% more ozone output than our Spa Eclipse. The Total Eclipse is now being offered in a 4 cell configuration for a 100% increase in ozone output. Take a look below at our exciting product line.

ECLIPSE Ozone Generator Installation & Maintenance The most common installation method allows ozone to be dissolved into pool water through an adjustable injector manifold assembly that is installed into the plumbing system following all other equipment. DEL injector manifolds contain a Mazzei injector and a ball valve. The injector manifold is installed as the last piece of equipment before the return to the pool/spa (shown below). The ball valve is used to redirect the water flow through the injector.
TOTAL ECLIPSE Ozone Generator Installation & Maintenance The TOTAL ECLIPSE has a built-in injector and recirculation pump for 24-hour independent operation. The TOTAL ECLIPSE can be installed at time of construction or on existing pools as shown in the diagrams below. TOTAL ECLIPSE New Pool Installation n ia l a r a p S Notes 1 Installing of the Total Eclipse no less than 12” above water level is recommended.
ECLIPSE Suction-side Installation If your pool has copper piping, solar panels, or extreme pressure loss, use the suction-side introduction method. With this method, no injector manifold is required. The vacuum created by the pump pulls the ozone in from the ozone generator. Any undissolved ozone is vented off by the filter. Pool professionals appreciate this method because the ozone helps degrease the filter The ECLIPSE suction-side installation diagram is shown below. n s Au au arts .

Spa Ozone Generator Installation & Maintenance There are many ways to install ozone on a spa. Please log onto our Website www.delozone.com to download an Eclipse spa ozone manual from our library (also includes ZO-301/302 and CDS-16 spa ozone generation units). These days, spa manufacturers have “ozone ready” spas. This means that there is a dedicated port for the ozone to enter, thus bringing ozone through an air line and through the jets (either the main jets or a dedicated ozone outlet).
Cloudy Water in a Pool Don’t Worry; In This Case, It’s Good What Causes Cloudy Water? Cloudy water can be caused when an ozone generator is first installed because the ozone oxidizes the organics in the water causing them to form a chain which then becomes visible to th eye and gives the water the cloudy appearance. Another way water can appear cloudy is with an imbalance in the water. Always check to make sure the pH, alkalinity and calcium hardness are balanced.
Algae—What You Should Know Ozone Does Not Kill Algae!* Why Doesn’t Ozone Kill Algae? • Ozone is destroyed immediately when it makes contact with any oxidizable substance in the water. How? Ozone is very reactive - it is oxygen with an extra oxygen atom hanging on. When the ozone hits something (could be a virus, some bacteria or suntan lotion), it releases an oxygen atom (O1) and creates an oxide of that material. All that is left is a molecule of oxygen (O2).
Commonly Asked Questions Why don’t we need an air dryer with the Eclipse? The Eclipse series was designed for residential pools (not commercial pools). Therefore, the concentrations of ozone necessary to produce a healthy bathing environment are relatively small. Air dryers or oxygen concentrators are used to remove the moisture (air dryer) and nitrogen (oxygen concentrator), thus bringing the concentration of ozone up.
Commonly Asked Questions (continued) With regard to ozone, how are “grams per hour” and “ppm” related? Which should I look at when comparing ozone systems? This is an easy question, but creates the most controversy in the ozone market. Although it is easy to compare test results, it is the test results that are not always reliable. DEL uses high-end, calibrated testing equipment to test our products, as well as our competitors’ products.
Commonly Asked Questions (continued) How does ozone work with other sanitizers? Bromine: ozone works well with bromine. With bromine, you should keep between a 1.0PPM and 2.0PPM. Bromine works better on covered or indoor hot bodies of water, such as a spa. Some people choose to sanitize their pool with bromine. If you have any comments on an ozone/bromine system, please let us know: 800-676-1335 or o3info@delozone.com. a p S Baquacil/Baqua Spa: ozone works well with these products.
THE PERFECT COMBINATION Ozone, Chlorine, and Mineral Systems What we believe makes for an extra safe, sanitary swimming environment...Ozone, chlorine (which can be reduced to 0.5 ppm), and a mineral system! Do you really need all three? You can get away with just chlorine, or a combination of chlorine and ozone or a mineral system. However, if you have a “busy” pool (children or young adults, pets, foliage, frequent rain, humidity, high temperatures, etc.
THE PERFECT COMBINATION Ozone, Chlorine, and Mineral Systems (continued) So why do you need a mineral system? The mineral system (there are many to choose from-ask your local dealer) will act as a backup algaecide and bactericide. It will insure that the water is always clean in case one of the other systems goes out (i.e. you forget to add chlorine or your ozone system is not operating). The use of the mineral system with ozone will further support the use of minimal levels of residual chlorine.
THE DEL Website www.delozone.com Our website contains valuable information to help you choose the perfect ozone generator. There is a library and Q&A Forum in which you can post a question that a DEL staff member (or anyone else who wants to) will answer. Visit the library for product information, specifications, manuals, articles, an online copy of this book, and even pictures of the most popular electrical spa plugs, and a listing of product replacement lamps, chips, and electrodes.
