Welcome to the Aqua Systems family of customers. Thank you
for placing your condence in us to help improve your water.
Our goal is to provide water quality solutions with lasting
performance. We are here to ensure the ongoing success-
ful operation of your water treatment system, and we want to
hear from you anytime you need assistance.
The Eradicator Air Induction Filter (AIF) is a product line
with multiple solutions for managing problem well water.
The AIF technology is effective in controlling both mild and
excessive levels of iron and sulfur. The AIF uses air as an
oxidizer, introducing it through the control valve. So, the AIF system does not require an external device, such as an air
compressor, to induce the air into the process.
Due to variables found from well to well, treating problem water is not rened to a small set of solutions. Although there are
standard systems in the AIF family, the AIF can be congured to specically address the problems of a particular well. This
manual will address the fundamentals of the product line and the standard models. However, it is possible that your AIF
system was designed to be site specic. Refer to the model number if you have questions for your system provider.
The AIF water lters are designed with Aqua Systems’ exclusive SmartChoice™ Gen II line of controls. The SmartChoice™
line wis designed with the owner in mind. Most water treatment systems on the market today are designed to be disposable.
The SmartChoice™ is designed to be a lasting appliance that can provide a lifetime of operation. The Exchangeable Com-
ponent Maintenance System allows for easy and efcient maintenance solutions. Each major part of the SmartChoice™ is
a replaceable component that is easily removed. Although it may be years before the rst service is required, this system
offers you the ultimate in long-term care. This system makes maintenance expedient and cost effective. Due to the knowl-
edge required in treating well water, we encourage maintenance on AIF systems to be done by a trained technician.
Aqua Systems recommends that AIF systems be installed by a trained technician. There are many issues involved in suc-
cessfully treating problem water that go beyond putting the pipes together. This manual is written for the owner. It covers
the basic installation requirements and the simple settings that an owner will need to know. It is not intended to be a com-
prehensive service and installation manual. If you have questions, please feel free to contact the factory or your local dealer.
Aqua Systems and our professional dealers are always prepared to assist you.

Maintenance Manual
How the Eradicator Air Induction Filtration (AIF) Systems Work
Air is a powerful oxidizer for both iron and sulfur. Historically, air has been utilized in water treatment through aeration tow-
ers, injection of compressed air, or by using an inline venturi. Aqua Systems AIF technology is a breakthrough because
air is introduced through an induction venturi that is built into the control valve. This allows a single tank to be used as an
aerator and a ltration system.
The AIF systems retain a head of air in the top of the tank during each treatment cycle. Each regeneration process purges
that air from the tank before backwashing the media bed. Fresh air is introduced after the media has been cleared of the
debris it has ltered from the water. The fresh air is introduced through the venturi. As the air is introduced, it displaces the
water in the tank, exposing the media to fresh air. This exposure of air to the media sets up oxygen sites on the surface of
the media, which provides the action it needs to perform. The head of air begins the oxidation process, while the oxygen
sites on the media complete the process by holding the iron and sulfur in the media bed.
Limitations of the AIF Systems:
• In order for the AIF Iron Filters to function, the pH of the source water must be at or above 7. If the pH is
below 7, you must include the pH adjustment option when treating iron.
• The water supply must have adequate ow and pressure to backwash the applied system. Be sure to
reference the required backwash rate of a specic model when considering an application. The minimum
requirement for the smallest system is 5 gallons per minute while maintaining a minimum of 20 psi.
• Water supplies may change over time. It is possible for the source water conditions to deteriorate beyond the
capability of an applied system months, or even years, after the initial installation.
• There will always be some effervescence to the water with this system. This effervescence is caused by
residual air in the water. This milky appearance is most noticeable immediately after a new installation. It
could take 30 to 90 days to settle out as the media fully absorbs the water, and expels the excess air.
• If you have a reverse osmosis (RO) system, the air will be noticeable in the drinking water as well. In fact, the
membrane in the RO system will actually concentrate the air and make it more noticeable. This too will soon
settle to a minimum.
• This residual air in the efuent water may loosen iron, or sulfur, build up from plumbing systems. If you are
installing an AIF system where the water pipes have a build-up inside, it may take a few weeks, or more, to
clear out the water lines. You may notice debris expelled from the tap on occasion as this build up is released
and cleaned from the plumbing system. This may require you to clean the faucet aerators, until the debris is
clear.
• You should never introduce chlorine into an AIF Iron Filter. Chlorine, and other strong oxidizers, will
damage the special media.

Requirements for Proper Operation: Tips:
Water Pressure: The system requires a minimum of 20 psi
to be sustained with owing water of 5 gallons per minute or
greater. Maximum is 125 psi.
Flow Rate: A minimum of 5 gallons per minute is required
for proper operation. If less than 5 gallons per minute is
available, consult with your dealer for possible custom
congurations.
Water Temperature: The range of water temperature for
these systems is 40˚ F to 110˚ F.
Drain: A drain within 20’ of the system can be run with
1/2” tubing. Drains running over 20’ should use 3/4” tubing.
Maximum overhead rise should be ≤ 8’. Consult your dealer
for any drain > 30’ in length.
Special Drain Note: The drain must be a legal connection
with a code compliant air gap. It is critical that the drain be
secured tightly at each end, and anchored throughout the run.
The AIF systems will jolt the drain line during the release of
air. Be sure to protect the immediate area from any spray
that may occur at the air gap. The drain connections should
be thoroughly tested before completing the installation.
Electricity: An uninterrupted 110volt A.C. source is required
to operate AIF systems.
Special Electrical Note: You must make sure that the
power
outlet is not connected to a timer, or a switch.
Source water pH: If the pH of the source water
is < 7, you must consult with your dealer. The
pH adjustment option must be added if pH is
below this specication.
Freezing: The AIF system, drain, plumbing
and all other water xtures, must be protected
from freezing temperatures. Be sure that the
installation site is not exposed to temperatures
below 32˚ F.
Positioning: Be sure to position the AIF
system so it can be removed or accessed for
future servicing.
Outside Faucets: Outside faucets must be
bypassed from any AIF system. These systems
are not designed for watering lawns, lling
pools, or any other outdoor use.
Sand: If sand or sediment is present you must
install a sand separator, or sediment lter ahead
of the AIF system.
Chlorine: AIF systems will not work on chlo-
rinated water supplies. Chlorine, and other
strong oxidizers will damage the media bed in
AIF iron lters.

Pre Assembly
1. Carefully remove system from carton and inspect. The
system box should contain:
a. AIF Filter System
b. Bypass Valve
c. Owner’s Manual
2. Attach the bypass to the unit. (see gure 1 )
The bypass valve easily connects to the control valve body
using nuts that only require hand tightening. Hand tighten
nut connections between control valve and ttings, control
valve and bypass valve, and bypass valve and installation
ttings. The split ring retainer design holds the nut on and
allows load to be spread over the entire nut surface area
reducing the chance for leakage. The split ring design, in-
corporated into the bypass, allows approximately 2 degrees
off axis alignment to the plumbing system. The bypass is
designed to accommodate minor plumbing misalignments
but is not designed to support the weight of a system or
the plumbing.

Do not use Vaseline, oils, or any pe-
troleum lubricants on o-rings. A silicon
lubricant may be used on black o-rings
only.
Tip:
Take a moment to ll out the information
sections in the Owner’s Manual. It can
be a valuable tool in the future to have all
the installation data available to answer
any questions.
Tip:
3. Attach one of the available connection tting kits to the
bypass as shown in gure 1.
The nuts, split rings, and o-rings install the same as the
bypass. (see gure 2 )

Bypass Operation
1. Normal Operation Position: The in-
let and outlet handles point in the direction of
ow indicated by the engraved arrows on the
control valve. Water ows through the control
valve during normal operation and this posi-
tion also allows the control valve to isolate
the media bed during the regeneration cycle.
(see gure 1)
2. Bypass Position: The inlet and out-
let handles point to the center of the bypass,
the control valve is isolated from the water
pressure contained in the plumbing system.
Untreated water is supplied to the plumbing
system. (see gure 2)
3. Diagnostic Position: The inlet
handle points in the direction of ow and the
outlet handle points to the center of bypass
valve, system water pressure is allowed to
the control valve and the plumbing system
while not allowing water to exit from the con-
trol valve to the plumbing. (see gure 3)
4. Shut Off Position: The inlet handle
points to the center of the bypass valve and
the outlet handle points in the direction of
ow, the water is shut off to the plumbing
system . If water is available on the outlet
side of the lter it is an indication of water by-
pass around the system (i.e. a plumbing con-
nection somewhere in the building bypasses
the system). (see gure 4)
The bypass valve is typically used to isolate the control valve from the plumbing system’s water pressure in order to
perform control valve repairs or maintenance. The Eradicator bypass valve is particularly unique in the water treatment
industry due to its versatility and state of the art design features. The 1” full ow bypass valve incorporates four positions
including a diagnostic position that allows service work on a pressurized system while still providing untreated bypassed
water to the facility or residence. Its completely non-metallic, all plastic design allows for easy access and serviceability
without the need for tools.

Eradicator II AIF Systems Installation, Operation,and
Maintenance Manual
Installation
AIF System Placement
All plumbing must be done in
accordance with local
plumbing codes.
The control valve, ttings and/or bypass are de-
signed to accommodate minor plumbing misalign-
ments but are not designed to support the weight
of a system or the plumbing.
Do not use Vaseline, oils, other hydrocarbon
lubricants or spray silicone anywhere. A silicon
lubricant may be used on black o-rings but is not
necessary. Avoid any type of lubricants, includ-
ing silicone, on red or clear lip seals.
The nuts and caps are designed to be unscrewed or
tightened by hand or with the special plastic wrench.
If necessary, pliers can be used to unscrew the nut
or cap. Do not use a pipe wrench to tighten or
loosen nuts or caps. Do not place screwdriver in
slots on caps and/or tap with a hammer.
Do not use pipe dope or other sealants on
threads. Teon tape must be used on the threads
of the 1” NPT elbow or the 1/4” NPT connection (for
the Test Port). Teon tape is not necessary on the
nut connection or caps because of o-ring seals.
When assembling the installation tting package
(inlet and outlet), connect the tting to the plumbing
system rst and then attach the nut, split ring and
o-ring. Heat from soldering or solvent cements may
damage the nut, split ring or o-ring. Solder joints
should be cool and solvent cements should be set
before installing the nut, split ring and o-ring. Avoid
getting primer and solvent cement on any part of the
o-rings, split rings, bypass valve or control valve.
Caution:
The Eradicator AIF systems are to be installed before a water
conditioner. This allows the iron and sulfur to be treated before
the softening process. This also protects the water softeners’
performance from being hampered from the iron, or sulfur. A
water softener can normally be installed next to the outlet of
the AIF system. Never route the outside faucets, or an ir-
rigation system, through an AIF Iron or Sulfur system. These
systems are not designed for the volume load of lawn watering,
or other outside uses.
Special Note:
1. Find a location with:
A. Enough room to pull the system away from the
plumbing if necessary.
B. The main inlet water supply or pre-
plumbed connection point.
C. Adequate drain xture, capable of 5 gallons
per minute ow.
D. An electrical outlet that is not operated by a
switch or timer.
2. Place unit in the desired location. If oor is not level
the unit may be leveled with the built in adjustable
base by lightly tapping the unit on the oor.
3. There should be a minimum of 12’ of water line
between the AIF system connection and the water
heater.
If there is a three way bypass in the existing plumbing, inspect it
to make sure the bypass valve shuts off 100% when closed.

4. Before connecting the water lines:
A. Turn off the electric or gas to the water heater.
B. Turn off the main water supply to the building, an drain
off the pressure to all cold water outlets.
C. Determine which outlets are to be bypassed and make
provisions to connect them before the AIF system.
D. It is highly recommended to provide an inlet shut off
valve near the unit.
E. The inlet water line should be a minimum of 3/4” in size.
If yours is smaller, consult your dealer for required
adjustments.
5. With the above considerations, connect the water line to the
inlet of the unit, which is designated by an arrow on the bypass
pointing toward the control valve.
6. Connect the outlet which is designated by an arrow pointing
away from the control valve to the water line that feeds the
softener, or back to the main if a softener is not being used.
7. If the plumbing system is metal pipe (ex. – copper), install a
jumper ground wire and grounding clamps between the inlet
and outlet pipes to retain continuity of the plumbing.
8. Connect the drain on the AIF system to an approved air gap
drain. When using the 5/8” poly tubing for the drain line, con-
nect the nut to the line as illustrated in gure 1. If copper line
is used, be sure to pre-sweat and cool pipe & ttings before
attaching to the drain tting on the valve.
Turning on the water:
1. With all plumbing connections made, make sure the bypass
is in the “bypass” position. (See gure 3). Slowly turn on the
water supply valve until lines are pressurized. At nearby fau-
cet, turn on cold water and let it run for 2 – 3 minutes to ush
debris from the plumbing. Check for water leaks, repair any
leaks immediately before proceeding.
2. After conrming no leaks, and ushing the lines, proceed to
the Start Up instructions on page 11.

Installation
The drain line on the AIF system must be secure
at all points along the length of the drain run. The
drain line will jolt when the air is released during
the cycle. You must test the drain line security
before leaving any installation site.
Caution:
Make sure all plumbing connections
are completed before turning on water.
Check for and repair any leaks before
proceeding with start up of system.

Start Up
1. Plug transformer into 110v receptacle. The control will place itself
into the Filtering mode, and will ash a time on the display.
2. Set the current time of day. (See page 13)
1. Water should be turned on to the AIF system while in the ltering
mode. Do not initiate a “Regen” cycle before turning water on
to the system. To turn the water on, open the inlet side of the
bypass to the system. Water will ll the unit, and trap a head of
air in the top of the tank. This initial head of air will be used to
check the drain connection.
2. Once water has lled the tank, and is no longer owing into the
tank, you can test the drain connection. Review both connection
points of the drain line, and all fasteners over the length of the
drain line. Make sure that every part of the drain line is secure.
3. Once drain line security has been veried, you can initiate the rst
cycle. This will allow you to check the drain line to make sure that it is sending water to the drain, and that it is stable.
Push the “Regen” button and hold for 3 seconds. This will move the control to the back wash cycle. Immediately
check the drain line for secure positioning, and leaks. If the drain line is functioning properly, let the system complete
the backwash cycle.
4. The Eradicator AIF system control valve will automatically advance to the air induction cycle after backwashing for the
appropriate amount of time. You must let the system complete the air induction cycle, which will be 30 – 40 minutes
depending on the system size.
5. Once the air induction cycle has been completed, the Eradicator control valve will automatically turn off, returning the
system to the “Filtering” mode. Once the system has returned to the Filtering mode it is time to turn the system on to
the facility. To turn the AIF system on, turn the outlet handle on the bypass to point toward the line of the piping. At this
point the bypass should be in the service position, with one handle pointing toward the control valve, the other pointing
away from the control valve.
6. With the AIF system placed in service you need to rinse the system down. Turn on a cold water line in the facility.
The Eradicator display should show the spinning ow indicator. This veries that the water is owing through the AIF
system. Let the water run until it is clear.
Put Unit into Service:
Make sure that the electrical outlet used
is an uninterrupted outlet (such as outlet
that is operated by a switch).
All electrical connections must be connected
according to local codes.
Note:
When pushing the “REGEN” button to
advance cycles, let the control reach the
next cycle before pushing the “REGEN”
button again.
Note:
Turning Water On to AIF System:
The AIF system will retain a lot of air in the rst 30 - 90 days of operation. This air will make the water in the facility
have a milky look to it. This is to be expected as normal until the dry media has had the opportunity to fully absorb
the water. Water from the AIF system will always have effervescence to it because of the air in the treatment process.
However, it is much more signicant in the rst 90 days.

2. When the system begins to regenerate, the display will change to include inform-
ation about the step of the regeneration process and the time remaining for that
step to be completed. The system runs through the steps automatically and will
reset itself to provide treated water when the regeneration has been completed.
3. Sometimes there is a need to regenerate the system, sooner than the system calls for it, usually referred to as
manual regeneration. There may be a period of heavy water usage because of guests or a heavy laundry day.
4. To initiate a manual regeneration immediately, press and hold the “REGEN” button for three seconds until the
system starts the regen. To initiate a regeneration at the normal scheculed time, push and release the “REGEN”
button. The display will alternate from the current screen to “REGEN TODAY”.
