Introduction 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
reduced, 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, 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, woodwork surfaces clean easier, 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 the kind of water which 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.

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 printed warranty
disclaims liability for corrosion of plumbing lines, fixtures or appliances. If you suspect corrosion, your
Culligan Man 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 percent 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.)
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.
CAUTION! Do not use where the water is microbiologically unsafe or with water of
unknown quality without adequate disinfection before or after the unit.

The Culligan
Process
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 Regeneration.
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 Brine Refill.
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 Culligan Municipal also includes carbon media for chlorine taste & odor reduction).
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.

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 delayed regeneration is 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.
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.
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.
Up Flow Regeneration
Water flow is downward and regenerate flow is upward through the media tank. The significance of
this is that regeneration will be most effective in those parts of the resin bed which are treated with the
freshest regenerate solution. There will tend to be less hardness leakage with up-flow regeneration.
Proportional Brining
The control monitors your softened water usage making only enough brine to regenerate that part of the
resin bed that has been exhausted. In this way the amount of salt used relates directly to the amount of
softened water used, making it more efficient and cost effective. Proportional brining can only be used
with upflow regeneration. The Aqua-Sensor or meter can be used to initiate a regeneration.

Salt Supply,
Usage and
Service
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.

Regeneration There are several conditions that will cause the HE Twin Controller 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 initiate a regeneration.
