Introduction
This Advanced Features Supplement is a guide to
the Eradicator with EOG II external Ozone. The
Eradicator line of chemical free iron and sulfur
removal systems is enhanced with ozone during
the aeration cycle. Ozone is effective as a Super
Oxidant for water treatment.
The unique low voltage ozone generator has been
designed to t externally on the SmartChoice
Eradicator control valve in which both are operated by a single low voltage power supply. This approach
provides an attractive ozone system that is very efcient and simple to maintain. The generator is
power optimized to consistently deliver the highest quality of ozone to the system. The Eradicator with
Ozone is an advanced technology water treatment system. It is recommended that the owner arrange
for annual periodic maintenance by a qualied technician to achieve optimum long term performance.
The information in this guide is directed to an individual who has experience with Gen II Eradicator
systems, and related programming of the Gen II control. Review materials on the Gen II control
before proceeding with this guide.
The content of this guide is intended to provide an overall understanding of how the Gen II AQx control
will function with the ozone generator. There are specic procedures to be used during installation,
startup, and for long term periodic maintenance that are unique with the ozone components.
Contact the Technical Support Group for additional information.
Note:
Installing the Gen II with Ozone requires special provisions for all outdoor installa-
tions. Consult with Tech Services Group at Aqua Systems on outdoor installations
with Ozone.
Outdoor or Damp installations will decrease the performance and will increase the
frequency of Periodic Maintenance and should have the optional Dryer Kit added
for optimum performance.

Overview
The Eradicator Gen II O3, with ozone, is a breakthrough in chemical free ltration. The ozone is made
from oxygen, then converts back to oxygen after its effective function. Ozone expedites the oxidation
in the Eradicator’s aeration process. The ozone is made from ambient air that is pulled into the control
during the draw cycle. A 12 volt DC generator creates electrical arcing technology, inside of a sealed
tube, known as Corona Discharge (CD). When the air is exposed to the arcing electrical current, the
Oxygen in the air (O2)converts to Ozone (O3). Once the ozone has done its job inside the ltration sys-
tem, it converts back to Oxygen (O2), leaving the efuent water from the lter refreshingly oxygenated.
The ozone generated in the Eradicator’s aeration process works as a Super Oxygen source. This
technique provides much more oxygen for the oxidation of iron and sulfur, and for restoring oxygen
sites on the media’s surface, than ambient air alone.
The ozone is generated from the auxiliary circuit board that is mounted inside of the Gen II EOG II
cover. This Eradicator O3 is operated by a single power supply in which the O3generator is activated
by the AQx relay function. The programming to activate the ozone generator is in the Eradicator elec-
tronics package. The programming for this function should only be accessed by a qualied technician.
Gen II O3with Ozone
Note:
The Gen II AQx control is programmed to activate the ozone generator. The ozone gen-
erator will not turn on if the control is fast-stepped through cycles by using the REGEN
button. You must wait for the activation based on the number of minutes from the start
of the cycle.
This issue is very different from standard Eradicator setup. The installer / service techni-
cian must be informed of these differences before proceeding with install.

Overview
Note: This section is an introduction to the EOG II components.
Details on components and wiring are found later in this guide.
Gen II O3with Ozone
The EOG II Ozone system is mounted on the inlet side of the control valve with the wire harness
going through the backplate to the circuit board. This allows the control valve and the O3system to
operate with a single power supply. An optional air dryer which increases O3production and quality
can be added to this control using the single power supply (see separate Air Dryer instruction sheet).

EOG II
Wire Harness

Air Intake
Filter Stone
When the control stops in the Regeneration DN position, air is pulled into the control through the
air intake . The air is pulled through a porous stone as a lter. The air is pulled through the Corona
Discharge (CD) Tube. When the tube is activated by the relay controlled power supply, it creates an
electrical arc internally. The air is passed through this arcing where it is converted from Oxygen (O2)
to Ozone (O3). The ozone then travels through the special tubing, through the check valve, and the
brine tting,where it enters the lter system.

The Eradicator O3functions just as a standard Eradicator Filter with the addition of ozone that is pro-
duced during the air intake. The ozone is produced from ambient air that is entering the induction port
during the Regeneration Down cycle. The ozone generator is turned on through the Gen II AQx Relay
Function, after the control valve has already stopped in the Regeneration Down cycle, and air draw is
active. The ozone generation is not turned on during Back Wash or Rinse Cycles, and turns off before
the control exits the Regeneration Down Cycle. Turning off the ozone generator before the valve moves
from the draw cycle provides fresh air to run through the tubing, clearing out all ozone from the control.
Ozone remains in the tank air chamber until it is converted with service ow. The ozone can be purged
from the tank if desired with special programming. If it is desired to operate without the trapped air in
the head of the tank, refer to the instructions in the Tech Bulletin on programming to remove the air.
The ozone generator activates when needed through the Relay 1 module of the AQ x software. Relay
1 is set to Regen Time. The start point is set to the number of minutes that it takes the control to enter
the Regeneration Down cycle, plus one additional minute before turning on. This allows the control
to stop in the cycle and establish a stable draw of air into the control. The Relay 1 terminal block is
connected to a relay that turns the ozone generator’s auxiliary power supply on.
Factory Set Program Time:
Back Wash 8 Minutes Relay 1 - Set Regen Time
Rinse 4 Minutes Relay 1 - Set Point Start 13 Min
Regen DN 30 Minutes Relay 1 - Duration 28 Min
This says that the AQx Relay will activate 13 minutes after the start of the cycle, and turn off after 28
minutes from the start of the relay activation. The initial 13 minutes allows the control to stop in Regen
DN before ozone is produced, and it turns off the ozone after 28 minutes, which is 1 minute before the
control returns to service.

Note: When stepping the control manually through the cycles, with the REGEN button,
the Relay function is disabled. To check the ozone production, the cycle can be manu-
ally started, but the control must proceed with the time to reach the Relay Set Point. If
you push REGEN at any time during the cycling process, the Relay will not activate, and
if already activated, the Relay will turn off.

Plug the power supply into the receptacle. Refer to the main Eradicator manual for the instructions
for the start up procedure.
The programming for the O3 is already done for Eradicator O3systems, so no further action is
needed beyond the normal start up procedure.
Once set up is complete, start the Eradicator in a manual regeneration and let it complete the
regeneration.
It is highly recommended to have an annual inspection and maintenance on the Eradicator system
to keep it operating at optimum performance.
If any service or maintenance is required, have your customer contact you for this service.

Ozone is a gas that is made from oxygen. However, it can be an irritant to the eyes and respira-
tory system. When checking the system for ozone production, do not directly inhale the ozone.
Ozone can be detected by smell at a distance even when diluted with air. So use caution when
checking for ozone production. At low concentrations ozone has a very refreshing fragrance.
The check valve and tubing are special materials that are ozone resistant. Do not attempt to
replace any of these parts with alternates of any type. If additional parts are required for repair
or replacement, order ozone specic parts from the tables later in this manual.
Lift the entire brine elbow off at
the locking clip connection to the
control valve to check draw and/
or for ozone .
Setup Procedures
Special Considerations in Checking for Draw with Ozone
Gen II O3with Ozone
Note: Checking for ozone is done during the draw cycle.
Check for ozone by removing the lock clip on the brine elbow and lifting the entire
assembly up from the seated position. Then replace the brine elbow and clip in before
indexing the control to the next cycle. Only technicians familiar with the Gen II control
should attempt this test.
Once the draw cycle is pulling air and the EOG II has
activated, the brine elbow can be removed at the lock
clip. Lift the elbow up after the control has been draw-
ing air for a few minutes. This should release a small
amount of ozone into the air that can be detected by
smell. Place the elbow back into position and replace
the lock clip.
Note: Checking for ozone is
done during the draw cycle.

2. Use the plunger to pull Warm RO or DI wa-
ter into the syringe. The water should be luke
warm to the touch. If you have a good quality
RO bottled water, on a hot & cold cooler, a blend
of the two sides will provide a good solution for
cleaning.
(NOTE: Hot RO water can be used if nitric acid
buildup is severe.)
3. Push the 5/16 vinyl tubing over one end of
the CD tube. The tubing does not have to be
pushed over the barbed section of the tting.
Gently push the warm RO water through the
CD tube into a white container. Monitor the
discharge water. Continue until the water runs
clear. Repeat the step as needed until dis-
charge is clear.
4. Once the discharge is clear, push the excess
water out of the CD tube with air. Pull the plunger
back to ll syringe with air. Push the air through the
CD tube over the cup. Continue process to provide
some additional air after the water is completely
expelled. This air will expedite drying the CD tube.
It’s best to let the CD tube dry for 24 hours before
testing.
