Thank You
And Welcome To Your New World Of Better Living With
Culligan Water.
The Culligan HE Twin Water Softeners with Soft-Minder® Meter and Aqua-Sensor®
sensing device are tested and certed by WQA against ORD0902, CSA B483.1,
NSF/ANSI Standard 44 for the effective reduction of hardness (calcium and
magnesium), as veried and substantiated by test data.
For installations in Massachusetts, Massachusetts Plumbing Code
248 CMR shall be adhered to. Consult your licensed plumber for installation of
this system. This system and its installation must comply with state and local
regulations. The use of saddle valves is not permitted.
If this is your rst experience having soft, conditioned water in your home, you’ll be amazed at the
marvelous difference it makes. We promise that you’ll never want to be without it again.
Congratulations, too, on selecting one of the “rst family” of water conditioners in the prestigious
Culligan High Efciency Softeners. With Culligan’s many years of knowledge and experience
in water treatment, you can be condent that the model you selected has been designed and
engineered to provide years of service with a minimum of care and attention.
Some localities have corrosive water. A water softener cannot correct this problem and so its printed
warranty disclaims liability for corrosion of plumbing lines, xtures or appliances. If you suspect
corrosion, your Culligan Dealer has equipment to control the problem.
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.
Attention Culligan Customer:
The installation, service and maintenance of this equipment should be rendered by a qualied
and trained service technician. Your local independently operated Culligan dealer employs
trained service and maintenance personnel who are experienced in the installation, function and
repair of Culligan equipment. This publication is written specically for these individuals and is
intended for their use.
We encourage Culligan users to learn about Culligan products, but we believe that product

It’s All So Easy, So Economical, So Efcient, 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 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 lm.
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 nd that they can
reduce the amount of soap they use substantially. If you normally used a cup per wash load with
hard water, try using only 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 lm 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 xtures 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 xtures with a towel after
use. Formica, tile, walls, oors, 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 which 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.
Savings Galore
A water conditioner is frequently referred to as “the appliance that pays for itself”. You’ll nd that
your savings on soaps, detergents, cleaning aids, and personal care products will help your family’s
household budget. And if you place a price on your time, you’ll be most happy with the time saved
by your new family servant.
Water For Lawns And Household Plants
If possible, lawn sprinkling faucets should be supplied with hard water primarily because it is
uneconomical 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 efcient absorption of water by the plant root system.
Additional information may be obtained from your independently operated Culligan dealer.
Culligan Municipal Softener
With the Culligan Municipal softener you will experience the above benits in addition to the
reduction of chlorine taste and odor for a fresh, clean taste and smell.

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, xtures 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 ltering 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 veried 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.
How Your
Water
Conditioner
Works
Caution! Do not use where the water is microbiologically unsafe or with water of unknown
quality without adequate disinfection before or after the unit.

10 01023052
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. 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 Rell.
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 rst
directed up through the column of Cullex resin to ush 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 Rell: While the control valve is in the “Brine Rell 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 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 fullled without using an
excessive amount of salt.
C. 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 rell cycle.
Since a predetermined amount of salt is dissolved with each brine rell cycle, the salt must be
periodically replenished in order to maintain efcient operation. Your Culligan service person
will be able to tell you about how often salt must be added to the salt storage container.
