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.

Introduction
(cont.)

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 6.5 - 8.5. A pH level of 7.0 - 8.5 is optimal for iron
reduction and a pH level of 6.5 - 7.5 is optimal for hydrogen sulfide 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 three seconds. The
“REG” will light and blink. An immediate regeneration will also occur if a power outage has lasted
for more than three 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.

When and
How to
Bypass
Your Water
Conditioner
Normally, all water except outside lines passes through the water conditioner. There are times when
the water conditioner 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 conditioner, and you do not want to waste
conditioned 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 conditioners is a push-button 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.
Bypassed
To BYPASS, turn the blue knob clockwise (see directional arrow on end of knob)
until the knob stops as shown. DO NOT OVERTIGHTEN!
Soft Water
To return to SERVICE, turn the blue knob counter-clockwise (see directional arrow on end of knob)
until the knob stops as shown. DO NOT OVERTIGHTEN!
About 1-1/4”
A screwdriver shank may be
used in the slot (arrow) as a
lever for extra turning force if
needed.

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 7 – 9. Call your Culligan dealer for advice and save a service call.

Recommended
Preventative
Maintenance
The Culligan Iron Cleer water filter has been designed to provide a good, consistent service life.
Because of the nature of problem water, we recommend that the local Culligan dealer provide regular
maintenance/service contracts for the proper operation of your systems. The water filter service
begins with a multi point inspection of your water filter system in an effort to uncover any and all
problems that may exist. Listed below is a recommended list of maintenance items to be inspected at
a minimum of once a year (or more frequently depending on the raw water quality).

naturally aerated under well
system pressure. As water is
released to the atmosphere,
air molecules separate from
the water molecules.
1. This natural phenomenon
will typically dissipate to the
atmosphere in a matter of
seconds. If preferred, water
can be drawn and stored
in an open container prior
to use (i.e. fill a pitcher and
store in the refrigerator for
cool, fresh drinking water).
