IRON CURTAIN 2.0
The advantages of a multi-media bed are:
1. Longer runs between backwash times.
2. Caking of the bed and breakthrough turbidity are virtually
eliminated.
. Much higher service flow rates per square foot.
4. Higher degree of clarity because of the heavier, finer filter
media in the bottom.
The standard Iron Curtain System uses five layers of filter
media. The top layer is made up of large, lighter weight
particles. The second layer contains a slightly heavier media.
The third layer contains a much heavier media, smaller in
size than the one above. The fourth layer contains an even
heavier media. The fifth layer is a special support bed to
retain filter media so it does not pass through the distribution
system, and allows an even distributed flow of backwash
water.
Operation of Aeration System
The Iron Curtain System introduces air into the aeration tank
and bleeds off the old head of air automatically. A timer
controls the air recharge cycle and how frequently it occurs.
The timer turns on the air pump, opening the drain port and
the top air recharge port of the aeration tank. The air pump
runs for a pre-set amount of time, replenishing the head of
air and discharging excess water and/or air to drain.
Advantages Over
Other Systems
1. The original systems was tested and validated by WQA
under their S-200 Standard.
2. Uses no chemicals or salt.
. Eliminates the need for air injectors, venturis, or
micronizers.
4. No floats or air volume controls are used to regulate air
volume in aeration tank which “foul” from iron.
5. Two-tank system consisting of a pressurized aeration
tank and multi-media depth filter.
6. 110V aeration pump to recharge aeration tank.
7. "Piggy-back" plug allows control valve to be plugged into
same outlet.
8. Can be used on shared wells, municipal water supplies,
or with buried pressure tanks without additional equip-
ment.
9. Higher service flow rates.
10. Better filtration results.
11. U.S. Patent #B1 5,096,596 and patent pending.
12. Variable settings on air recharge that is independent of
backwash frequency.
Iron Filtration System
Aeration/precipitation/multi-media filtration for:
1. Iron Reduction/Removal
2. Manganese Reduction/Removal
. Hydrogen Sulfide Reduction/Removal
Principle of Operation
The Iron Curtain System uses a three step process of
ox dat on, prec p tat on, and mechan cal f ltrat on for the
reduction/removal of iron, manganese, and hydrogen sul-
fide. The process of how the Iron Curtain System does each
one of these separate procedures is the key to the successful
results this product has obtained in the market place. There
are two ma n components that make up the Iron Curta n
System. They are:
1. Iron Curtain 2.0 Aeration Assembly
2. Iron Curtain Multi-Media Depth Filter
1The f rst step n any ox d z ng process s to br ng the raw water nto nt mate contact w th a strong ox -
dant. This will begin to convert the dissolved element such as
iron or manganese to a physical particle or nonsoluble
precipitate. A strong, inexpensive, environmentally-safe oxi-
dant is oxygen, which makes up about 21% of ambient air. To
do this, the Iron Curtain System sprays water through a
regulated head of air in the aeration tank.
2The second step n th s three step process s to prov de adequate react on or contact t me for the
prec p tat on react on to go to complet on. This allows
time for the iron and/or manganese particles to become large
enough to filter out. The aeration tank with the Iron Curtain
System allows for several minutes of contact time at the rated
service flows, compared to only seconds on other systems.
It should be noted that this reaction time will also be affected
by temperature; the warmer the water the faster the reaction.
A low ph can slow the oxidation reaction of the iron. This
reaction time may also be affected by the presence of organic
material (such as tannins). If tann ns are present, f eld
tests have shown that they w ll not be removed and w ll
also h nder the ab l ty of th s system to effect vely remove
ron, manganese, and/or hydrogen sulf de. Installat on
of th s system on water suppl es w th more than 0.5 ppm
of tann ns w ll vo d warranty.
3The th rd and f nal step s f ltrat on for the removal of the prec p tates from the water. A WQA Water Filtration
Study Guide states:
“The ideal filter bed would be one with large grains at the top
to prevent the formation of a surface cake and to provide
large pores for course particles and small grains at the
bottom to entrap smaller particles. This allows the entire
depth of the bed to be used as a filter. This also allows for
longer filter runs and faster flow rates. Unfortunately, such an
ideal bed, when consisting of a single media is not possible,
the way to solve this problem is to use layers of media.”

Operating Conditions
The original Iron Curtain System has been validated by the
WQA under their S-200 Filter Standard for the reduction/
removal of iron, manganese, and/or hydrogen sulfide. The
concentration limits listed below reflect the maximum individual
limit that each contaminant was tested for separately without
any interference of other contaminants in the influent water.
In reality, these contaminants may be present in combination
which may limit the filter’s ability to remove these contami-
nants in higher concentrations. In some cases, individual
sellers of this equipment have had success removing higher
concentrations of contaminants—iron, for example—above
the limitations we have listed. If you are considering the
installation of this system for the reduction/removal of iron,
manganese and/or hydrogen sulfide levels that are above
operating conditions listed below, we recommend that you con-
sult your dealer for proper application. Installation of this
system under these circumstances may void part(s) and/or
all of the system warranty.
pH — The pH level of the influent water must be 7.0 or higher
for iron oxidation reaction to proceed per the engineering
specifications.*
Iron — This system is rated for a maximum of 10 ppm of
ferrous (clear water) and/or ferric (red water) iron.*
Iron Bacter a — If iron bacteria are present; more frequent
service may result, life of the Iron Curtain system may be
limited and the system may be unable to properly remove
iron. By properly controll ng the ron bacter a w th chlo-
r ne or other approved methods for bacter al reduct on,
the Iron Curta n System w ll funct on properly. One opt on
to control ron bacter a w th n the Iron Curta n s chlor ne
nject on dur ng the regenerat on cycle. In some n-
stances, cont nuous chlor nat on of the water supply may
be needed.
Hydrogen Sulf de — Sometimes referred to as "rotten egg"
odor. This system is rated for a maximum of 10 ppm
hydrogen sulfide. Hydrogen sulfide levels vary depending on
barometric pressure.*
Manganese — Limit 2.0 ppm; amounts present over 2.0 ppm
may gradually prevent iron removal. Note: For optimum
manganese reduction, pH should be greater than 8.5.*
Organ c Matter (Tann ns) – The presence of organic matter
such as tannins will prevent the oxidation process of converting
the dissolved element, such as iron or manganese, to a
nonsoluble precipitate or solid substance. In other words,
organics can tie up the iron preventing filtration. The presence
of organ cs such as tann ns above 0.5 ppm vo ds any
cla ms for th s system to perform as stated above. In some
appl cat ons, tann n levels below 0.5 ppm or the presence of
other organ cs may h nder the operat on of th s system.*
Chlor ne — The presence of chlorine in the raw water supply
ahead of this system should be limited to a maximum of 1.0 ppm
residual and preferably 0.5 ppm or less when fed continuously.
Total D ssolved Sol ds (TDS) — While TDS does not
directly affect iron removal, it is a good indicator of potential
interference. Most waters have TDS less than 500 and gener-
ally present no problems to iron reduction. If any ion becomes
excessive, it may cause failure of iron removal. A TDS more
than 750 ppm vo ds any cla ms for th s system to perform as
stated above.*
Pre-Installation Check List
Water Pressure: A minimum of 0 psi at a predetermined
continuous flow rate is required to backwash the filter properly,
with a maximum of 70 psi to be used.*
Actual Influent Flow Rate: (Water available from well pump,
service inlet, etc.) The actual flow rate must exceed the
backwash rate for the model of filter selected at a minimum of
0 psi for the entire length of the backwash cycle. See actual
backwash rates in the Specifications section on page 6.
Electr cal Requ rements for F lter Control: A continuous
110 volts is required to cycle the controls and aeration pump.
Make certain the electrical supply is always on and cannot be
turned off with another switch.
Ex st ng Plumb ng: The condition of the existing plumbing
should be free from lime and iron build-up. Piping that is heavily
built-up with lime and/or iron should be replaced.
Equ pment Locat on: See Figure 1,on page 7.
Locat on of Aerat on and F lter Tank: See Figures 1 on page 7.
These two tanks should be installed after the pressure tank and
as close to each other as practical. If you want to filter outside
hosebibs, be sure the filter system is properly sized to handle
the flow rates required for extended periods of time, in addition
to the normal household demand.
Dra n L nes: All filter system drain lines must be a m n mum
of 3/4" or equal to the size of the drain line connection at the
control valve or larger. Avoid overhead drain lines when
possible. If used, overhead drain lines are not to exceed a
height of five feet above the control valve and should be no
more than fifty feet in length.
Check Valve: On applications where there is a non-filtered
demand for water such as joint wells (where the filter system
is only installed in one of two or more homes), outside
hosebibs, farms with outbuildings, yard hydrants, etc. a spring
loaded check valve is provided and must be installed ahead
of the aeration tank. See Figures 1, on page 7. Install the
check valve in a vertical upflow position with a minimum 6"
water column above the check valve. This prevents air from
escaping past the check valve. If the check valve is installed
in a horizontal position, and there is a simultaneous demand
for both non-filtered and filtered water, the air head in the
aeration tank may escape backwards past the check valve
into the non-filtered water line.
By-Pass Valves: Always provide for a bypass on the filter
system. It is recommended that a bypass be placed on both
the aeration tank and the filter tank.
F ltered Water: Normally, filtered water is furnished to all
household lines; however, outside faucets are typically left on
raw water. If filtered water is provided to outside faucets, the
filter system must be sized accordingly.
Caut on: The water pressure is not to exceed 70 p.s.i.; water
temperature is not to exceed 110° F; filter system cannot be
subject to freezing conditions; filter system cannot be subject
to a negative pressure or vacuum. On installations where there
is the possibility of a negative pressure or vacuum, a vacuum
breaker or check valve must be installed at the inlet of the
conditioner. For example, if the water service is interrupted due
to a water pipe break, well pump being serviced, etc., a back
siphon could occur causing a vacuum or negative pressure on
the filtration equipment.

Installation Instructions
Your new Iron Curtain™ model IC-2.0 allows for simple
installation and start up. Installation diagrams are provided to
assist you. Use of these diagrams and the following proce-
dures will ensure that the system is properly installed.
1. Follow all state and local plumb ng and electr cal
codes!
2. The one-inch (1") check valve that is supplied must be
installed in the upflow position on the raw water supply
feeding the aeration tank. (See figure 1 page 7 for proper
check valve installation procedures)
. When installing an Iron Curtain Filter system it is common
to provide filtered water to some fixtures such as the
kitchen cold faucet. This is typically done as a matter of
personal preference. In rare occassions it has been
noted that the customer may experience some air in the
filtered water line on the morning after regeneration. It
has proven to be beneficial to plumb the line for the filtered
only water fixture in a downward direction from the inlet of
the softener (12 inches recommended), then make a
reverse turn and go upward toward the fixture. Under-
standing that air always rises to the highest point in a
water system, and it cannot naturally flow downward.
(Figure 1, page 7)
4. The raw water supply from the outlet of the check valve
must be connected to the down-flow inlet connection on
the aeration tank. Refer to the st ckers marked nlet/
outlet for proper connect ons. A factory by-pass valve
is available and should be installed on the aeration tank
assembly. (See page 10 for details). Leave the aeration
tank on by-pass at this time.
5. The outlet from the aeration tank is then connected to the
inlet of the filter tank. A factory by-pass valve is available
and should be installed on the filter tank assembly.
(See page 10 for details).
6. Connect the outlet of the filter system to the water system
lines you are filtering.
7. The IC-2.0 aeration head assembly has a /8” drain
connection that must be run to a drain. This can tee into
the drain line of the filter or to a drain independent of the
filter drain. Drain line emits surges of excess air from
aeration tank and must be secured. Tubing has been
supplied along with a /4” male threaded adapter. (See
page 10 for details).
8. There is a 1/4” tube size vent port off of the solenoid valve
which is vented to the atmosphere. This will normally
expel very little moisture unless an internal seal fails
within the valve body. Th s vent should be run to a dra n
to prevent any water damage to the surround ng area,
should the soleno d fa l. Th s must dra n downward to
an open atmospher c dra n separate from the f lter
dra n.
9. Recommend 1” diameter pipe between aeration tank and
filter tank.
Start-Up
1. Once all plumbing is finished and with the unit on bypass,
flush the plumbing system until water is clear and no
foreign material is detected.
2. Plug in aeration pump. Open the inlet valve on the by-pass
to the aeration tank and allow the tank to fill with water and
come up to full line pressure. You do not have to wait for
the air recharge cycle (air pump running) to finish before
proceeding to the next step.
. Open the outlet valve on the by-pass(s) for the aeration
tank and filter.
4. With the filter control valve in the service/filtering position,
slowly open the inlet valve on the by-pass to the filter and
run water at a filtered water fixture until the water is clear.
Then continue to slowly open the filter inlet valve fully and
continue to run water at a filtered water faucet until water
is clear.
5. Start-up is complete.
6. IMPORTANT: Do not backwash your Iron Curta n
F lter for 24 hours.

Aeration Control Center
Your new IC-2.0 Aeration Control is factory pre-set to cycle the
air compressor once every 24 hours. To adjust the frequency
for the air pump refer to the wiring schematic. The timer has a
fixed run time, which cannot be adjusted up or down. To
manually initiate an air recharge cycle, unplug the power cord
and plug it back into the electrical outlet. The air pump will
begin to run and will automatically shut off.
Iron Curtain Filter Control
Your Iron Curtain Filter is factory preset to backwash every third
day. Adjust as necessary but never backwash less often than
every three days. See filter control owners manual for details.
Regeneration Frequency
Your Iron Curtain Filter System contains a special filter media mixture
which allows it to filter iron longer than standard filters between
backwash regenerations. However, it is our recommendation to
leave factory settings as is, unless you wish to backwash more
frequently. You will have to backwash more frequently if you
have higher amounts of iron, iron bacteria, hydrogen sulfide,
and/or manganese present in your water supply. You will also
have to regenerate more frequently if you notice iron bleed
through before the end of the normal service run.

Step 2.
Aerat on Operat on A r Recharge Cycle
When energized, the air pump sends air through the solenoid valve into one end of the shuttle valve. Once
air pressure in the shuttle valve is greater than the water supply pressure at the other end of the shuttle
valve, the piston shifts to the open position. In the open position, the bleed-off port discharges excess water
and old air to the drain port through a flow restrictor. Simultaneously, the air inlet port opens to provide
a direct connection between the air pump and the top of the aeration tank. The air pump runs for a preset
period of time recharging the head of air in the aeration tank.
A r Recharge Shut Off
The timer turns power off to the air pump and the solenoid valve at the end of the recharge cycle. The
solenoid valve then closes the port between the air pump and the shuttle valve. The port between the
shuttle valve and the atmosphere opens and releases air pressure. This allows water pressure to shift
the piston to the closed position. With the piston in the closed position, the air recharge inlet port is closed
and direct communication between the bleed off tube and the drain port is also closed.
T mer Operat on
A timer controls the air recharge cycle and how frequently it occurs. The timer simultaneously energizes
the air pump and the solenoid valve. After a preset amount of time, the timer shuts off the air pump and
de-energizes the solenoid valve.
Soleno d Valve Operat on
The solenoid valve is a three-way valve having ports that connect to the air pump, shuttle valve and the
atmosphere. In the service cycle, the solenoid valve is de-energized and closes the port to the air pump,
providing a positive shut-off to the pump. This prevents water from backing up into the air pump and
damaging the pump. In the air recharge cycle, the solenoid valve closes the port to the atmosphere and
opens the port from the air pump.
Shuttle Valve Operat on
In the service position, water pressure holds the shuttle valve piston in the closed position, trapping the
airhead in the aeration tank and closes the air recharge inlet port and drain port. During air recharge cycle,
air pressure is greater than the water pressure and forces the shuttle valve piston in the open piston. The
shuttle valve has an internal pressure relief valve that will relieve pressure (greater than 100 psi) that may
build up in the aeration tank. This precautionary function protects components from failure due to
excessive pressure.
IRON CURTAIN FLOW DIAGRAMS
Step 1.
Aerat on Operat on Serv ce Cycle
In the service cycle, raw water enters the inlet
port of the aeration tank and is directed through
the inlet diffuser. The oxidation process begins
when the water passes through the inlet diffuser
and cascades through a head of air. This air/
water contact oxidizes the iron, manganese,
hydrogen sulfide in the water. The water is
directed toward the bottom of the tank and
travels through the pick-up tube. It then passes
through the outlet of the aeration tank to the inlet
of the filter tank.
F lter Tank Operat on Serv ce Cycle
Raw water enters the filter tank through the inlet
port of the filter control valve. Upon system
demand for filtered water, water is directed to
the top of the tank and flows downward through
the multimedia filter bed toward the lower dis-
tributor. Oxidized iron particles are trapped by
the filter bed as the water passes through.
Filtered water enters the lower distributor and
travels up the distributor tube to the outlet port
on the filter valve.

The rinse cycle packs the clean filter
bed. Raw water enters the control valve
through the inlet port and is directed
downward through the filter bed into the
bottom distributor, up the distributor tube
into the control valve. Water is then
directed through a specific flow restrictor
and out the drain port to be discharged to
drain.

F lter Tank Operat on
Backwash Cycle
Reversing the flow of water through the
filter bed and backwashing dirty water to
the drain cleans the filter bed. Raw
water enters the filter control valve
through the inlet port and is directed
down the distributor tube and out the
lower distributor at the bottom of the
tank, flowing upward through the multi-
media filter bed toward the top of the
tank into the control valve. Water is then
directed through a specific flow restrictor
and out the drain port to be discharged
to drain.

Winterizing Iron Curtain
Systems (Optional)
In certain climates where houses and/or cottages are not
heated during the winter months, Iron Curtain Systems must
have the water removed from them to protect from damage
due to freezing. Following are instructions for “winterizing”
Iron Curtain Systems.
Draining of the Iron Curtain System should be done in
conjunction with or after the complete water distribution
system is drained to prevent water from entering the Iron
Curtain System after it has been winterized. After Iron Curtain
System and water distribution system are drained, make sure
all water shut-off valves are open.
Instruct ons for w nter z ng Iron Curta n Systems:
1. Before shutting off the water, manually shift the filter
control valve to the backwash cycle.
2. Unplug the electrical cords for the Aeration Control Cen-
ter and the Filter Control Valve.
. Let unit backwash for 15 minutes.
4. Place the Aeration Tank Bypass in shut off mode - See
page 11. (Make sure you leave the filter tank bypass
in the service position.)
5. Plug the electrical cord for the Filter Control Valve back
in and manually shift the control valve to the fast rinse
cycle.
6. Unplug the filter electrical cord.
7. You will need to plug the fitting for the /8” drain
connection on aeration head. /8” plug available from
manufacturer - p/n 11-P108125.
A. Consult your dealer if assistance is needed with this
step.
8. Plug in the electrical cord for the Aeration Control
Center.
A. This will start the Air Recharge Cycle.
B. Water/air will drain out the filter drain pipe.
C. You need to leave in this cycle until only air is
discharging out of the drain pipe.
D. You will need to repeat this step if the air pump
shuts off while water is still discharging to the
drain.
9. To start pump unplug the electrical cord for the
Aeration Control Center, re-plug in.
10. Turn off water when only air is discharging to drain.
11. Remove the plug installed in the pressure relief valve
previously installed.
12. Loosen the union nuts on the Aeration Tank Bypass
Valve on the Aeration Head. (Make sure you loosen
the nuts between the bypass and the aeration head.)
1 . Move the Aeration Tank to the side.
14. You then can proceed with winterizing the rest of the
building.
15. You will need to make sure there is no water left below
the 1” Check Valve. (Consult your dealer if you have
questions.)
16. Make sure the Aeration Tank Bypass Valve is in the
service position.
17. System is now winterized.
18. When turning the system back on, refer to the start up
instructions on page 5.
