It’s All So Easy, So Economical, So Efficient, So Enjoyable!
Kind To Skin And Complexion
Soft water will help prevent red, itchy or dry skin because there are no hardness impurities to cause
soreness, no soap curd to coat the skin. Shaving is easier, smoother—either with a blade or electric shaver.
Bathing And Showering
You’ll use far less soap with conditioned water. Use your soap very sparingly—not as you did before soft
water. Just a quick rinse removes all lather, leaving your skin pleasantly smooth and silky because now
it’s free of sticky soap curd and film.
Saves Washing Costs. Helps Control Environmental Pollution
Soft water washes whiter and cleaner with less soap or detergent. Because the hardness impurities are
removed, your soap can concentrate solely on washing. People usually find that they can reduce the
amount of soap they use substantially. If you normally use a cup per wash load with hard water, try using
1/3 cup depending on the size of your wash load and the degree of soil. Different amounts are required, but
you can use less with softened water. An added bonus is the fact that your washable fabrics will last longer.
Super Hair Conditioning
Soft water is great for scalp and hair care. No insoluble deposits are formed.
Hair is shinier, softer, more manageable. Reduce the amount of shampoo you have normally used.
Dishes Are A Delight
Washed by hand or in a dishwasher, glassware, dishes, and silver wash cleaner and easier.
Follow your dishwasher manufacturer’s instructions. Soft water promotes sanitation because
no greasy hard water film can form to collect or harbor bacteria.
Easier Housekeeping, Gleaming Fixtures
You’ll be amazed at the marvelous difference. Just a swish of the cloth and the bathtub or shower and fixtures
are clean and sparkling. Imagine, no scouring! No hard water scum to cause rings, streaks, spots, and stains.
To keep their gleaming luster, simply wipe fixtures with a towel after use. Formica, tile, walls, floors, and
woodwork surfaces clean easier and stay clean longer. You’ll save on cleaning aids and save on time.
Saves Water-Heating Energy, Helps Water-Using Appliances
Soft water reduces the formation of rock-like hard water scale that encrusts water heaters, hot water pipes,
shower heads, and water-using appliances. This scale can cause premature maintenance and failure.
Elimination of hard water also provides substantial energy savings because scale acts
as an insulator, wasting electricity or gas used to heat water.
Water For Lawns And Household Plants
If possible, lawn sprinkling faucets should be supplied with hard water primarily because
it is not economical to soften so much water.
Household plants are much more sensitive than lawns with respect to which kind of water is
best. First, because they receive no rainfall and, second, there is little or no drainage of the soil.
Preferably they should be watered with rainwater or water which is low in mineral content such
as distilled or demineralized water. Softened water is not recommended for house plants because
a build-up of sodium in the soil may interfere with efficient absorption of water by the plant root
system. Additional information may be obtained from your independently operated Culligan dealer.
Introduction

801024584 E 11/19
How Your Water
Conditioner
Works
Why Water Gets Hard And How It Is Softened
All of the fresh water in the world originally falls as rain, snow, or sleet. Surface water is drawn upward
by the sun, forming clouds. Then, nearly pure and soft as it starts to fall, it begins to collect impurities
as it passes through smog and dust-laden atmosphere. And as it seeps through soil and rocks it gathers
hardness, rust, acid, unpleasant tastes and odors.
Water hardness is caused primarily by limestone dissolved from the earth by rainwater. Because of this,
in earlier times people who wanted soft water collected rainwater from roofs in rain barrels and cisterns
before it picked up hardness from the earth.
Some localities have corrosive water. A softener cannot correct this problem and so its written warranty
disclaims liability for corrosion of plumbing lines, fixtures or appliances. If you suspect corrosion, your
Culligan dealer has equipment to control the problem.
Iron is a common water problem.
The chemical/physical nature of iron found in natural water supplies is exhibited in four general types:
1. Dissolved Iron—Also called ferrous or “clear water” iron. This type of iron can
be removed from the water by the same ion exchange principle that removes the
hardness elements, calcium and magnesium. Dissolved iron is soluble in water and
is detected by taking a sample of the water to be treated in a clear glass. The water
in the glass is initially clear, but on standing exposed to the air, it may gradually turn
cloudy or colored as it oxidizes.
2. Particulate Iron—Also called ferric or colloidal iron. This type of iron is an undissolved
particle of iron. A softener will remove larger particles, but they may not be washed out
in regeneration effectively and will eventually foul the ion exchange resin. A filtering
treatment will be required to remove this type of iron.
3. Organic Bound Iron—This type of iron is strongly attached to an organic compound
in the water. The ion exchange process alone cannot break this attachment and the
softener will not remove this type of iron.
4. Bacterial Iron—This type of iron is protected inside a bacteria cell.
Like the organic bound iron, it is not removed by a water softener.
When using a softener to remove both hardness and dissolved iron it is important that it regenerates more
frequently than ordinarily would be calculated for hardness removal alone. Although many factors and
formulas have been used to determine this frequency, it is recommended that the softener be regenerated
when it has reached 50–75% of the calculated hardness alone capacity. This will minimize the potential for
bed fouling. (Iron removal claims have not been verified by the Water Quality Association and IAPMO R&T.)
If you are operating a water softener on clear water iron, regular resin bed cleaning is needed to keep
the bed from coating with iron. Even when operating a softener on water with less than the maximum
of dissolved iron, regular cleanings should be performed. Clean every six months or more often if iron
appears in your conditioned water supply. Use resin bed cleaning compounds carefully following the
directions on the container.
NOTICE Do not use where the water is microbiologically
unsafe or with water of unknown quality without
adequate disinfection before or after the unit.

Your Culligan water conditioner consists of three basic components,
(A) the Control Valve, (B) the Mineral Tank, and (C) the Brine System.
A. Control Valve
The exclusive Culligan control valve automatically
performs a variety of tasks that are necessary for the
proper operation of your water conditioner. These tasks,
commonly referred to as cycles or operating positions,
are Service, Regeneration, and Brine Refill.
1. Service: While the control valve is in
the service cycle, hard water is directed
down through the column of Cullex®resin
where hardness minerals are removed
from the water. The softened water is then
directed into your household plumbing lines.
The ability of the Cullex resin to remove
hardness minerals needs to be periodically
replenished; this is referred to as …
2. Regeneration: While the control valve
is in the regeneration cycle, water is first
directed up through the column of Cullex
resin to flush accumulated sediment out of the
resin and down the drain. Then, the regenerant
brine solution is slowly drawn
from the bottom of the salt storage tank
of the Brine System and is directed down
through the column of Cullex resin, restoring the
ability of the resin to remove hardness minerals
from your water supply. Once completed, the
regeneration cycle is followed by …
3. Brine Refill: While the control valve is in the brine refill cycle, a predetermined amount of
water is directed to the salt storage tank of the Brine System so that additional salt can be
dissolved to provide the brine solution that will be needed for the next regeneration cycle.
B. The Mineral Tank
The Mineral Tank contains the Cullex resin column, Cullsan®underbedding, and an outlet manifold.
The number of gallons of hard water that can be softened by the Cullex resin column before it needs
regeneration is called the “capacity” of the resin column, and depends upon the amount of hardness
minerals in each gallon of water (expressed as grains per gallon) and upon the amount of regenerant
brine solution (expressed as pounds of salt) passed through the resin column during regeneration.
Your Culligan service person, taking into account the hardness of your water and the amount of
softened water your household may reasonably expect to use each day, has carefully established
how often the softener will regenerate and how much salt will be used for each regeneration. This
will ensure that all of your soft water needs will be fulfilled without using an excessive amount of salt.
C. The Brine System
The Brine System consists of a salt storage container and hydraulic Dubl-Safe™valve. The salt storage
container holds the salt that is used to make the regenerant brine solution. The hydraulic Dubl-Safe
valve limits the amount of water that is returned to the salt storage tank during the brine refill cycle.
Because a predetermined amount of salt is dissolved with each brine refill cycle, the salt must
be periodically replenished in order to maintain efficient operation. Your Culligan service person
will be able to tell you about how often salt must be added to the salt storage container.

The Culligan
Process

10 01024584 E 11/19
Modes of
Operation
Water Meter Mode
In water meter mode, the controller keeps track of the quantity of water that has flowed through the
resin bed. Based on the influent water hardness and the hardness capacity of the resin bed, a service
life expectancy in the quantity of softened water is calculated and programmed into the control. When
the set point is reached, regeneration is triggered. If the predict mode is not selected the regeneration
will start at time of regeneration. In immediate mode the regeneration starts as soon as the regeneration
signal is provided. If time clock backup is set and the capacity has not been exhausted but the days
since last regen is greater than time clock backup, setting the softener will immediately regenerate.
Aqua-Sensor®Mode
The Aqua-Sensor is a conductivity probe that senses when the hardness front passes through
the resin bed. It functions independently of the influent water hardness so therefore, is useful in
conditions when the influent water hardness varies throughout the year. It provides for the most
efficient mode of operation. In addition to sensing when a resin bed is exhausted, it can also be
used to determine when the brine solution is rinsed from the resin bed during the Brine Draw/Slow
Rinse cycle triggering the control to move to fast rinse. This patented feature provides water
savings by optimizing the amount of rinse water required to completely rinse out the resin bed.
Smart Brine Tank Probe
The smart brine tank probe monitors conditions inside the brine tank. It predicts when
salt needs to be added to the brine tank, detects the presence of salt-bridging, eductor
line plugging and brine tank overfilling.
Wireless Remote Control
The wireless remote control displays the current status of the water softener or filters and
allows for remote control. It can be located up to 200 feet away from the softener (depending
upon building construction materials). The wireless remote displays information about softener
performance, problems, days of salt remaining and allows remote control for regeneration.
The wireless remote control is designed to communicate at 915 MHz and to work without
interference with other 915 MHz devices such as cordless telephones and baby monitors.
Modem
The modem allows for the system to be remotely monitored detecting problems before they
occur, to schedule salt delivery when it is needed and to keep the system software up to date
with the latest advances.
Culligan ConnectTM
The Culligan Connect™ interface is an intuitive mobile app and is available on both iOS and Android.
Users will see their daily and weekly usage patterns graphically represented and instantly updated
each time they open the app. In addition, low salt alerts and the ability to put the unit in bypass mode
or regeneration from anywhere offer an all new level of control and convenience.
Manual Regeneration
Manual regeneration can be initiated via the softener control valve or wireless remote display.
Manual regeneration can be initiated to begin regeneration immediately or that night.
To immediately initiate regeneration, press and hold for at least ten (10) seconds.
To cancel a delayed regeneration, press and hold for at least five (5) seconds.

11
01024584 E 11/19
Predict Mode
The Predict Mode is used with the flow meter to determine the optimum regeneration point.
Before the regeneration starts, the control will compare the remaining capacity value with the
average daily water use. If the average daily water usage is less than the reserve capacity, the
controller will wait 24 more hours before regeneration. If the reserve capacity is less than the
average daily water usage, the control will initiate regeneration. This works in delay mode only.
At any time, if the total capacity value is reached, the control will initiate an immediate regeneration.
Pre-Rinse Mode
The Pre-rinse mode is used to pre-rinse the softener resin bed or filter media. The pre-rinse in flow
meter mode will occur after the control has sensed that no water has flowed through the control for a
period of X hours (can be set through the programming menu). When the control is in this mode, once
the X amount of hours have elapsed the control will cycle to the fast rinse position for the pre-set length
of minutes and then return to the home or service position.
Down Flow Regeneration
Water and regenerate flow downward through the media tank.
Dial-A-Softness®
Dial-A-Softness is a manual adjustment built into the control valve that allows for variable
hardness bypass into the softened water. The hard water bypass can be adjusted from
0% to 30%. The Dial-A-Softness also increases the softener capacity in proportion to
the percent hard water bypass (less salt used).

Regeneration
There are several conditions that will cause the control to trip a regeneration. The screen displays
REGEN Tonite when the control has signaled for a regeneration. Regenerating is displayed while
the control is in regeneration. The following are conditions that will call for regeneration:
1. When the Soft-Minder®meter has recorded the passage of a predetermined number of gallons.
2. When the Aqua-Sensor®Probe senses the hardness in the Cullex Media.
3. At the preset time, when the number of days without a regeneration is equal
to the regeneration interval (timeclock backup) setting.
4. At the preset time, when Regen Tonite is selected. The screen displays Regen Tonite.
5. Immediately, when the Regen Now is selected. The screen displays Regenerating.
6. Immediately, if power to the unit has been off for more than three hours and the time
of day has been restored.
7. At the preset time based on “Day-of-Week” Regeneration setting.
Follow either procedure to bypass the softener or to initiate a manual regeneration
or automatically bypass the softener at the control valve or the remote display.

Salt is the mineral used to “recharge” your water conditioner. A brine solution is automatically
made up in the bottom of the salt storage container, the Cullex® resin beads in the mineral tank
are flushed with the brine solution as a step in the recharging process.
Your Culligan Water Conditioner has been carefully designed to get the greatest amount of softening
capacity from the salt it uses. Here is some pertinent information about salt usage, types and service.
Salt Economizer
This control is set at the time of installation, and determines salt usage according
to the water hardness, number of persons in the household, and water usage.
What Kind of Salt is Best
All Culligan Water Conditioners are designed to use any water conditioner
salt of good quality, including rock, pellet, solar, or “evaporated” types.
All rock salt, regardless of source, contains insoluble material which collects
at the bottom of the salt storage tank and requires periodic clean-out.
If purified salt products are used, the salt storage compartment will require
less frequent clean-out, but you must check more frequently for “bridging.”
Regardless of what type of salt is used, we recommend Culligan Brand Salt as
suggested by your Culligan Dealer. He or she is the expert and can provide you
with the best product for your Culligan Water Conditioner.
Automatic Salt Delivery Service
Ask your Culligan Dealer for details about salt delivery service. You can have your salt supply replenished
on a regular basis. Whether you have automatic delivery service or pick up salt from your Culligan Dealer,
you will be getting quality salt packaged according to rigid Culligan specifications. Using Culligan Brand
Salt will help assure continued efficiency and trouble-free operation of your water conditioner.
The modem allows for the system to be remotely monitored, detecting problems before they occur, to
schedule salt delivery when it is needed and to keep the system software up to date with the latest advances.
NOTICE Sodium Information: Water softeners using sodium chloride for regeneration
add sodium to the water. Persons who are on sodium restricted diets should
consider the added sodium as part of their overall sodium intake.

Things to
Check Before
You Call for
Service
If you unexpectedly experience changes in your 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 softener should be manually regenerated
according to instructions on page 17 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. Plug in the transformer then reset
conditioner to the correct time of day.
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 change—such as daylight savings—will disrupt your
softener’s regeneration schedule by causing the timer to run off-schedule. Reset the timer to the
correct 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 (see page 23). 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 conditioner (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., will result in more water usage
and will require more capacity from your softener. You can reprogram your regeneration
schedule by following the directions beginning on page 17. Call your Culligan dealer for
advice and save a service call.
