IT’SALLSOEASY,SOECONOMICAL,SOEFFICIENT,SOENJOYABLE!
KINDTOSKINANDCOMPLEXION
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.
BATHINGANDSHOWERING
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.
SAVESWASHINGCOSTS.HELPSCONTROLENVIRONMENTALPOLLUTION
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 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 amountsare required,
but you can use less with softened water. An added bonus is the fact that your washable fabrics will last longer.
SUPERHAIRCONDITIONING
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.
DISHESAREADELIGHT
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.
EASIERHOUSEKEEPING,GLEAMINGFIXTURES
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.
SAVESWATER-HEATINGENERGYHELPSWATER-USINGAPPLIANCES
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.
SAVINGSGALORE
A water conditioner is frequently referred to as “the appliance that pays for itself”. You’ll find 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.
WATERFORLAWNSANDHOUSEHOLDPLANTS
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
soilmayinterfere with efficientabsorption of water bytheplantrootsystem.Additionalinformationmay be obtainedfromyourindependently
operated Culligan dealer.
Introduction
INTRODUCTION 3

Why Water Gets Hard And How It’s 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.Asoftener 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.Asoftener 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
becalculated for hardnessremovalalone.Although many factorsandformulashave been usedtodeterminethis 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.
If you are operating a water softener on clear water iron, regular resin bed cleaning is needed to keep the be 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.
How Your Water Conditioner Works
4CULLIGAN®MARK100WATERSOFTENEROWNER'SGUIDE

YourCulligan waterconditioner consists ofthree basic components,(A) theControlValve, (B)the MineralTank, and(C) theBrineSystem.
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,ANDBRINEREFILL.
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: Whilethe control valveis in the“BrineRefill cycle”,apredetermined amount ofwater is directedto the saltstorage
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 exclusiveBondedTripl-Hull™MineralTank containsthe Cullex resincolumn,Cullsan®underbedding, and anoutlet manifold. Note:
TheMineralTankofAqua-Sensor®modelsalsocontainsa mineral sensor devicethatdetermineswhenthe Cullex resin needsregeneration.
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 serviceperson, 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 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.
Since 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 serviceperson will be able to tell you about how often salt must be added to the salt storage
container.

Display
As shipped from the factory, the display of the board will turn off if there has been no keyboard activity for a 1 minute period.To have a the
display constantly lit, press the STATUS button until the number 10 icon is lit. Next, press the UP arrow. A “d” for
disable will appear in the display. To have the display blank again, press the UP arrow.An “E” will appear in the display.
Power Loss
TheAccuSoft®circuit board is equipped with a Hi-Cap Capacitor and EEPROM memory chip. The capacitor is capable of maintaining the
time, for at least one day, in the event of a power outage. The EEPROM ensures that the individual programming parameters of your
softener 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 regen-
eration 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.
Meter Operation
For units equipped as a Soft-Minder®meter, the gallons remaining can be viewed by pressing the STATUS button until the screen is blank.
Press the DOWN arrow until the number 15 icon is illuminated. The display must be multiplied by 10 to determine the actual gallons
remaining before the unit calls for a regeneration.
Regeneration
To initiate an immediate regeneration, press the “REGEN” button twice.An immediate regeneration will also occur if a power outage has
lasted for more than four hours and the Immediate Regeneration option is chosen. Ask your Culligan Dealer about
this feature.
Aregeneration at the Time of Regeneration will occur if so signaled by theAqua-Sensor®sensing device or the Soft-Minder meter. If the
blanking option is engaged, the display will light indicating a regeneration signal has been received. It will then blank itself after 1 minute.
The “REGEN” enunciator on the display will also be lit.
Service
The Culligan®Mark 100 water softener is equipped with a self diagnostic program to insure optimal operation of your water softener.
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 will be the only item displayed when service is required on the control.

Salt is the mineral used to “recharge” your water conditioner. Abrine solution is automatically made up in the bottom of the salt storage
container, the Cullex®resin beads in the tall, thin tank are flushed with 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.
Regardless of what type of salt is used, we recommend Culligan Brand Salt as suggested by your Culligan Dealer. He 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 condi-
tioner.
CAREANDCLEANINGOFYOURCULLIGANWATERCONDITIONER
Following these simple precautions will help assure continued trouble-free service and keep your Culligan Water Conditioner looking
like new for years.
Do not place heavy objects on top of the salt storage tank or timer cover.
Use only mild soap and warm water when cleaning the exterior of the conditioner. Never use harsh, abrasive cleaning
compounds or those which contain acid, such as vinegar, bleach and similar products.
Important: Protect your water conditioner and the entire drainline from freezing temperatures. DANGER: If your
unit should freeze, do not attempt to disassemble it. Call your Culligan Dealer.
Should service, adjustment or trouble-shooting information be needed which is not covered in this Owner's Guide,
a complete Service Manual covering the conditioner that you own may be obtained from your Culligan Dealer.

Salt Supply, Usage and Service

A periodic clean-out of the Salt Storage Tank is necessary to keep your Culligan Water Conditioner at peak operating efficiency.
Do it at least every 2 years when the salt supply is low. Follow these step-by-step procedures:
Toolsneeded:
• Scoop
• Clean, bucket-size container
• Phillips-head screwdriver
• Garden hose, Household scrub brush or sponge
1. Remove the salt storage tank cover and the cap from the brine valve chamber.
2. Lift the brine valve out of the brine valve chamber and set aside in an upright position.
3. If you’d like to save any clean, dry salt remaining in the tank, remove it and place it in a clean container.
4. Using the scoop, dig out and discard as much remaining salt, water and debris as possible.
5. Remove the brine valve chamber by removing the chamber retaining screw and nut.
6. Remove the salt plate at the bottom of the tank.
7. Lay the salt tank on its side and direct a brisk stream of water from your garden hose to its inside to rinse out all residue.
8. Using a household scrub brush and a mild soapy solution, clean the salt plate. This will complete the tank cleaning.
9. Stand salt tank upright. Make sure to place the tank on a flat, smooth, solid surface.
10. Replace the salt plate. Place brine valve chamber in position and affix with screw and nut.
11. Insert the brine valve into the chamber and replace brine valve chamber cap.
12. Fill the salt storage tank with 4 to 6 inches of water.

SOFTENER SPECIFICATIONS
Refer to the Specifications, Familiarization, and Warranty sections of this Owner's Guidefor more specific product information. To avoid
contamination from improper handling and installation, your system should only be installed and serviced by your Culligan Man.
Performance will vary based on local water conditions. The substances reduced by this system are not necessarily in your water.
Culligan water softeners are designed to work with any salt of good quality, although it is recommended that you ask your local
Culligan man for his suggestion on the best type and grade of salt to use in this softener.
This Culligan Mark 100 water softener is tested and validated by WQAtoANSI/NSF Standard 44 for the effective reduction of calcium and
magnesium(hardness) alongwith Barium andRadium 226/228*.
This softener is efficiency rated, it has a Demand Initiated Regeneration (D.I.R.) feature which complies with specific performance specifi-
cations intended to minimize the amount of regenerant brine and water used in their operation. The softener has a rated salt efficiency of
not less than 3350 grains of total hardness exchange per pound of salt used (based on NaCl equavalency), and shall not deliver more salt
thanits listedrating. The efficiency is measuredby a laboratorytest described inANSI/NSF Standard 44. This testrepresentsthe maximum
possible efficiency that the system can achieve. Operational efficiency is the actual efficiency achieved after the system has been installed.
Operational efficiency is typically less then the efficiency due to individual application factors including water hardness, water usage, and
other contaminants that reduce the softener's capacity.
