Water Quality
Verify that raw water iron, pH level and alkalinity are within recommended limits.
Iron—A Common Water Problem
The chemical/physical nature of iron found in natural water supplies is exhibited in four general types:
1. Ferrous Iron—Also referred to as “dissolved iron” or “clear water” iron. The Iron-OX5 is rated
to remove up to 5 ppm of this type of iron. If a glass is filled with water containing ferrous iron
the water will initially be clear. Upon standing and being exposed to air the water will gradually
turn cloudy and colored as the ferrous iron oxidizes to ferric iron.
2. Particulate Iron—Also called ferric iron. This type of iron is an undissolved particle of iron.
The Iron-OX5 filter will effectively remove these particles but it is not the intended design
of the system. If there is a significant amount of ferric iron additional filtration treatment
may be required prior to the Iron-OX5.
3. Organic Bound Iron—This type of iron is strongly attached to an organic compound in the water.
The oxidation / filtration process used in the Iron-OX5 will not remove this type of iron.
4. Bacterial Iron and Colloidal Iron—These types of iron, like organic bound iron, will not be removed
by the Iron-OX5 filter.
Principles of Operation - Iron-OX5 Aeration System
The Culligan Iron-OX5 system utilizes the principle of oxidation to convert ferrous iron to ferric iron,
resulting in removal of the iron as a filterable particle. The process is accomplished by water entering
|the filter tank being immediately exposed to an “airhead” at the top of the filter tank to begin the
oxidation process. The filter media acts a catalyst to help complete the oxidation reaction and retain
the precipitated iron. Periodic backwashing purges the accumulated iron particles from the filter tank
and re-classifies the media bed.
After the backwash cycle the Iron-OX5 control valve replenishes the airhead in the filter tank
during the “Air Draw” cycle. During this cycle Air is educted into the filter tank in sufficient volume
for the required airhead. During the “Rinse”cycle the air charge is compressed and stored within
the filter tank and the filter media is rinsed prior to the system returning to the service cycle.
CAUTION! Do not use where the water is microbiologically unsafe or with water
of unknown quality adequate disinfection before or after the unit.
Pressure - Although the system is designed and tested to operate at a maximum pressure of 60
psi, it is not expected that the system should be exposed to such pressure for extended operation.
Culligan recommends following the IAPMO Uniform Plumbing code section 806.2 by installing a
Pressure Regulating Valve if the water pressure is greater than 60 psi. Operating on pressures
above the UPC for extended periods of time can increase the service frequency and failure of
replacement parts. On a private water system, make sure the minimum pressure (when the pump
starts) is greater than 20 psi (140 kPa).
CAUTION! The use of a pressure reducing valve may
limit the flow of water in the household.
Temperature - Do not install the unit where it might freeze, or next to a water heater or furnace
or in direct sunlight. Outdoor installation is not recommended, and voids the warranty and UL Certifications.

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 reconditioning cycle at the preset reconditioning cycle time. The time of day
will need to be reset in order to return the reconditioning cycle 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.
Reconditioning
To initiate a reconditioning cycle at the preset time, press the “REGEN” button. The “REG” light
will light. To initiate an immediate reconditioning cycle, press and hold the “REGEN” button for
at least five seconds. The “REG” will light and blink. An immediate reconditioning cycle will also
occur if a power outage has lasted for more than three hours and the "Immediate" programming
option has been selected. Ask your Culligan Dealer about this feature.
A reconditioning cycle will occur at the programmed Time of Reconditioning if signaled by the flow meter.
The “REG” enunciator on the display will also be lit.
Service
The Culligan Medallist Series® 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.
