CORONA DISCHARGE (CD) OZONE SYSTEMS
Ozone is manufactured in the CD ozone generator by drawing in air, which is composed of 20%
oxygen (02), and exposing it to multiple high voltage electrical discharges. This causes the oxygen
molecules to dissociate and reassemble as ozone (03). The ozone is drawn into the water by an
injector/mixer, killing any bacteria, viruses or mold spores it contacts. Ozone is generated on-site,
eliminating the need to store toxic and corrosive chemicals. The corona discharge method is the
most efficient way to produce large amounts of ozone.

Chemical Formula for
Corona Discharge Ozone
•Advanced Water Engineering, Inc. Tech manufactures high output corona discharge systems capable
of producing enough ozone to substantially reduce the consumption of other chemical disinfectants.
This reduction will make the water crystal clear and rainwater soft while allowing for cost savings on
chemicals and maintenance. Also, important health advantages will be realized, including no hair
discoloration, excessive skin dryness, faded swimming apparel, or irritation to the eyes, nasal
passages and throat. Ozone reacts to waterborne contaminants significantly faster than other
disinfectants and the primary by-product is pure oxygen.
•Advanced Water Engineering, Inc. ozone systems are built with the finest components available. All are
air-cooled and use a venturi injection system to create the best possible contact and mixing of ozone
while maintaining a high level of safety.
•In contrast to ultraviolet ozone generators, corona discharge systems produce a much higher
concentration of ozone and in much larger quantities. In addition, the annual expense of replacing
lamps and checking ballasts is unnecessary with corona discharge systems. Corona discharge ozone
generation is the most economical and effective method to use on large, commercial water
applications.
UNCRATING AND INSPECTION
Freight Inspection
All equipment should be thoroughly inspected immediately upon delivery. If any damage is noticed,
promptly notify the freight line and request an on-site inspection. Thoroughly inspect all packing
materials prior to discarding. Inspect all plumbing fittings and tubing for packing material
inadvertently lodged in any openings.

PRODUCT DESCRIPTION
The Advanced Water Engineering, Inc. corona discharge ozone system consists of two main components:
• Ozone Generator with built-in Air Preparation • Venturi Injector Manifold
Ozone Generator
The ozone generator houses the ozone reaction chamber, power supply and all electrical components
directly related to the production of ozone. Ozone is produced when the feed gas is exposed to a high
voltage electrical current inside the reaction chamber.
Air Preparation
The Advanced Water Engineering, Inc. CD10/AD ozone system is equipped with a heat regenerative
desiccant air dryer built into the same enclosure. Corona discharge ozone generators are much more
effective, produce more ozone and require far less maintenance if an air preparation unit is included. The
air preparation system lowers the dew point of the feed gas. Moist feed gas (air) will cause nitric acid to
form inside the generator, which decreases ozone production and if not removed, causes corrosion and
eventual failure of the generator’s internal components. The ability of the ozone generator to produce
ozone is drastically reduced as the dew point rises above -550C. The air dryer desiccant material has an
average life expectancy of five years under normal use.

PRODUCT DESCRIPTION (continued) Injector Manifold
The ozone gas is injected into the filtered water return line by means of the injector manifold. This
allows the ozone to be injected into the water under a vacuum condition, which is the safest
technology available. The injector sizing will vary depending on the flow characteristics of the job.
Atypical injector is shown below. The #978 injector manifold fits 1” plumbing, while the #1 584
injector manifold handles a higher flow rate and fits 2” plumbing.
Layout and Dimensions of Typical Injector Manifolds
Booster Pump (optional upgrade)
it is the booster pump that creates the side stream ozone injection loop. Without this pump, the
main circulation pump could he overburdened, slowing the filtered water return and decreasing the
turnover rate. The booster pump operates all the ozone mixing/injection equipment and enhances
the turnover rate. We recommend the use of a booster pump with systems having a marginal flow
rate.

INSTALLATION
Placement of Equipment
Select a location for the ozone equipment that is as close as possible to the ozone injection point. Situate
the unit in a manner suitable for convenient electrical access. The CD1 0/AD enclosure is not rain proof, so
it is important to choose a location that will keep the system away from direct weather and excessive heat.
Four mounting holes are located on the back of the ozone generator for convenient wall mounting.
Mounting hardware is not provided.
There are two basic installation methods for the CD1 0/AD system: “Full Flow”, where the ozone is injected
directly into the main water return flow, and “Side Stream”, which requires a booster pump on a new,
separate side stream plumbed off of the main water return line. The side stream plumbing is dedicated to
the ozone system only. Follow the instructions below for the alternative you will be using:
FULL FLOW INJECTOR MANIFOLD PLUMBING CONNECTIONS
Refer to the ‘Full Flow Installation’ diagram and follow the instructions below if the ozone is being injected
directly into the lull flow of the pool’s return line:
1. Tap into the return line after the pump, filter and heater. The ozone injection point should be the last
component in line and as far as possible from the injection point of the residual chemical.
2. Glue in the proper injector, noting the direction of flow (indicated by an arrow on the injector).
Once the injector is installed, the vacuum may be adjusted as described in the ozone operation
Section.

INSTALLATION (continued)
SIDE STREAM BOOSTER PUMP AND INJECTOR MANIFOLD PLUMBING
CONNECTIONS
This alternative set up utilizes a two-inch side stream ozone treatment method. Typically, the feed water for
the side stream is pulled from the main filtered water return after the filter, before the heater and returned
at a point after all other equipment and before the residual chemical injection point. The pH adjustment
point will always be the last item in this sequence.
Use Schedule 80 PVC for all plumbing connections whenever possible. Also, it is recommended that
unions and valves are used wherever practical. Ozone rapidly deteriorates a variety of compounds; the
following is a list of materials that may be used with ozone:
Viton Teflon® Stainless Steel EPDM
Silicon Kynar® Concrete Hepalon
NOTE: Be sure to use good plumbing practices and install unions
and isolation valves wherever the situation dictates, i.e. pump removal,
etc. Secure all plumbing with unistrut or similar hardware.
In the main water return line, after the filter but before the heater, install a wet tap (or a tee) and
isolation valve.
Install the booster pump. Secure the pump on a housekeeping pad with the appropriate mounting
hardware.
If an optional auxiliary control relay (i.e. flow switch) is being used, install it into the line after the
ozone booster pump.

Install the injector manifold after the ozone booster pump, making sure to note the correct flow
direction of the injector manifold. The location of the injector manifold and booster pump is
dictated by the mechanical blueprints. The check valve assembly is strapped to the injector
manifold. Unstrap and install the check valve assembly to the injector.
Tubing Installation
Install the check valve assembly into the injector. Connect the 1/4” Teflon tubing from the OZONE
OUT fining on the bottom of the ozone generator to the check valve assembly on the injector.
Secure by tightening the fitting around the ¼” Teflon tubing after insertion.
