Introduction Operation
Step 1.
Aeration Operation Service 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.
Filter Tank Operation Service 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 distributor. 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.
Step 2.
Aeration Operation Air 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.
Air 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.
Timer Operation
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.
Solenoid Valve Operation
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.
2

Shuttle Valve Operation
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.
Step 3.
Filter Tank Operation - 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
multimedia 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.
Step 4.
Filter Tank Operation - Rinse Cycle
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.
Operation Of Aeration Pump
The Iron-Cleer™ system introduces air into the aeration tank and bleeds off the old head of air
automatically. The exchange of the air into the aeration tank is controlled independently of the
recharge frequency of the filter media tank, allowing the air to be exchanged on a more frequent
basis. During an air exchange cycle, the air compressor pumps fresh air into the aeration tank and
the air eliminator solenoid exhausts the old air.
Advantages Over Other Systems
1. No chemicals or salt.
2. No air injectors, venturis, or micronizers.
3. No floats to regulate air volume in aeration tank which “foul” from iron.
4. Two-tank system consisting of a pressurized aeration tank and multi-media depth filter.
5. 110V aeration pump to recharge aeration tank.
6. Can be used on shared wells, municipal water supplies or with buried pressure tanks without
additional equipment.
7. Better filtration results.

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, however, we know that these contaminants may be present in combination which may limit
the filter’s ability to remove these contaminants 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 beyond the printed
operating conditions below, we recommend that you consult the manufacturer 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 - 8.5. A pH level of 7.0 - 8.5 is optimal for iron
reduction.
Iron — This system is rated for a maximum of 10 ppm of ferrous (clear water) and/or ferric (red
water) iron. Consult the factory if iron bacteria is present.
Hydrogen Sulfide — Often referred to as rotten egg odor, hydrogen sulfide will be reduced
significantly on water supplies containing less than 5 ppm. Consult the manufacturer if hydrogen
sulfide concentrations is greater than 5 ppm.
Organic Matter (Tannins) — 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 non-soluble
precipitate or solid substance, allowing it to be filtered out. The Iron Cleer™ is not designed to
remove organic bound iron.

Operating
Conditions

Familiarization
Power Loss
The AccuSoft®circuit board is equipped with a Hi-Cap Capacitor and EEPROM memory chip. The
capacitor is capable of maintaining the time, for at least two days, in the event of a power outage.
The EEPROM ensures that the individual programming parameters of your filter are not lost.
If the power outage lasts long enough to drain the Hi-Cap Capacitor, the control will flash “12:00 PM”
when power is returned to the control. The unit will continue to keep time from the moment power is
restored, and will initiate a full regeneration at the preset regeneration time. The time of day will need
to be reset in order to return the regeneration to its preset time.
If you live in an area where power outages occur with a regular frequency, a battery backup option
is available for ensuring that the time of day is properly maintained. Contact your Culligan Dealer for
more information.
Regeneration
To initiate a regeneration at the preset time, press the “REGEN” button. The “REG” light will light. To
initiate an immediate regeneration, press and hold the “REGEN” button for at least five seconds. The
“REG” will light and blink. An immediate regeneration will also occur if a power outage has lasted for
more than four hours and the Immediate Regeneration option is chosen. Ask your Culligan Dealer
about this feature.
A regeneration at the Time of Regeneration will occur if so signaled by the Soft-Minder meter. The
“REG” enunciator on the display will also be lit.
Service
Culligan’s Iron-Cleer®water filter is equipped with a self diagnostic program to insure optimal
operation of your water filter. Should service become necessary, a phone icon will appear in the
display. If this condition occurs, call your local Culligan Dealer for assistance. The phone icon and
error code will be the only items displayed when service is required on the control.

Normally, all water except outside lines passes through the water lter. There are times when the
water lter should be bypassed, using the Cul-Flo-Valv®Bypass, or a 3-way bypass valve. You
should bypass:
1. If lines to outside faucets do not bypass the water lter, and you do not want to waste soft
water on lawn sprinkling or other outside uses.
2. If you are going away on vacation and want to save salt by not having the unit recharge while
you’re away.
Bypass Valve
In the back of Culligan water lters is a Cul-Flo-Valv®Bypass. To bypass unit, simply turn the blue
knob clockwise. To return to soft water service, reverse the procedure - turn the blue knob counter-
clockwise.

Things to
Check Before
You Call for
Service
If you unexpectedly experience problem water, make these simple checks before calling your
Culligan dealer. One of the following conditions may be the reason for your interruption of service.
Important
If any of the following conditions is found, the water filter should be manually recharged according to
instructions on page 5 after you have corrected the problem.
Power Supply
Check your power supply cord. Is it plugged fully into the electric outlet? Be certain that the outlet
is not controlled by a wall switch which has been turned off. Reset conditioner to proper time of day
and then plug in.
Blown Fuse
Check the house fuse or circuit breaker panel. Replace a blown-out fuse or reset an open circuit
breaker.
Power Failure
Any interruption in your power supply or time changes - such as daylight savings - will disrupt your
filter’s recharge schedule by causing the timer to run off-schedule. Reset timer to proper time of day.
Bypass Valves
Check to see if they are in the proper position. Cul-Flo-Valv®Bypass, if used, should be in the
“Service” position. If hand valves are used, see that inlet and outlet valve are opened and that the
bypass valve is closed.
No Water
If you aren’t getting any water flow at all, make sure your water supply is working. Open a tap ahead
of the filter (outside tap) to see if you have any water pressure. If you have water pressure, check
the bypass valve. If it is in the Service position, put it into the bypass and call your Culligan dealer
for service.
Increased Usage
Guests, family additions, new water-using appliances, etc., all will result in more water usage and will
require more capacity from your filter. You can reprogram your recharging schedule by following the
directions on pages 6 and 7. Call your Culligan dealer for advice and save a service call.
10

Care and
Cleaning of
Your Water
Conditioner
11
Following these simple precautions will help assure continued trouble-free service and keep your
Culligan Water Conditioner looking like new for years.
1Use only mild soap and warm water when cleaning the exterior of the conditioner. Never use
harsh, abrasive cleaning compounds or those which contain acid, such as vinegar, bleach and
similar products.
2Important: Protect your water conditioner and the entire drainline from freezing temperatures.
DANGER! If your unit should freeze, do not attempt to disassemble it. Call your Culligan
Dealer.
3Important: Culligan water lters are sold for use on potable water, only. If at any time the water
becomes contaminated, such as during a “boil water” situation, the operation of the water lter
should be discontinued until it is veried that the water is again potable. To do this, screw the
blue knob on the back of the water lter against the barrel of the bypass valve. Then, call your
Culligan dealer to have your system sanitized before it is placed back into service.
4Should service, adjustment or trouble-shooting information be needed which is not covered in
the Use and Care Guide, call your Culligan Dealer.
If you have further questions, please call your local independently operated Culligan dealer. He or
she will be glad to be of assistance to you.

The 10” and 12” Iron-Cleer filters have been tested and certified by WQA against S-200 for the
effective reduction of iron.
The 10” and 12” Iron-Cleer filters have been tested by WQA against NSF/ANSI 42 for the reduction of iron. The concentration of
iron in water entering the system was reduced to a concentration less than or equal to the permissible limit for water leaving the
system as specified in NSF/ANSI 42.
Testing was performed under laboratory conditions, actual results may vary.
Performance Indicator: If water flow decreases or a noticeable odor returns, the filter should be reconditioned. If conditions do not
improve, contact your local Culligan Man. He can determine if your filter requires servicing.
Regeneration Frequency: Regeneration frequency will vary depending upon water conditions.
Refer to your Installation and Operation Instructions, Parts List and Printed Warrantees for more specific product information.
To avoid contamination from improper handling and installation, your system should only be installed and serviced by your
Culligan Man. Performance may vary based on local water conditions. The substances reduced by this product are not
necessarily in your water.
