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 sore-
ness, 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 re-
duced, 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 uneconomi-
cal 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 demineral-
ized 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 hard-
ness, 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 par-
ticle of iron. A softener will remove larger particles, but they may not be washed out in regen-
eration 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 …
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 dis-
solved 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 con-
tainer 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 periodi-
cally 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.

01023052
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 expec-
tancy 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 solu-
tion 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 overfill-
ing.
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 sched-
ule 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 regen-
eration 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 re-
generation 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

801023052
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.
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).

Application
Water Quality
Verify that raw water hardness and iron are within limits. Note the hardness for setting the salt dosage
and recharge frequency.
Iron is a common water problem. The chemical/physical nature of iron found in natural water supplies is
exhibited in four general types: Dissolved Iron, Particulate Iron, Organic Bound Iron and Bacterial Iron.
Hardness sample kits are available through your local Culligan dealer.
Pressure
If pressure exceeds 125 psi (860 kPa), install a pressure reducing valve (see materials checklist). On pri-
vate water systems, make sure the minimum pressure (the pressure at which the pump starts) is greater than
20 psi (140 kPa). Adjust the pressure switch if necessary.
CAUTION! Do not use where the water is microbiologically unsafe or with
water of unknown quality adequate disinfection before or
after the unit.
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. Use the Culligan Outdoor HE softener
for outdoor installations. The Culligan Outdoor HE softener has been certified by Underwriter’s Laborato-
ries for outdoor installation. If installing in an outside location, you must take the steps necessary to assure
the softener installation plumbing, wiring, etc. Areas well protected from the elements (sunlight, rain, wind,
heat, cold), contamination, vandalism, etc. as when installed indoors.
Location
Space Requirements
Allow 6–12 inches (15–30 cm) behind the unit for plumbing and drain lines and 4 feet (1.3 meters) above
for service access and filling the salt container.
Floor Surface
Choose an area with solid, level floor free of bumps or irregularities. Bumps, cracks, stones and other
irregularities can cause the salt storage tank bottom to crack when filled with salt and water.

Drain Facilities
Choose a nearby drain that can handle the rated drain flow (floor drain, sink or stand pipe). Refer to “Ta-
ble 3. Height of Discharge Above Floor Level Operating” on page 22, for maximum drain line length.
NOTE Most codes require an anti-siphon device or air gap. Observe all local
plumbing codes and drain restrictions. The system and installation must
comply with all state and local laws and regulations.
Electrical Facilities
A 10-foot cord and wall mount plug-in transformer are provided. The customer should provide a recepta-
cle, preferably one not controlled by a switch that can be turned off accidentally. Observe local electrical
codes.
NOTE The softener works on 24 Volt/60 Hz electrical power only. Be sure to use the
included transformer. Be sure the electrical outlet and transformer are in an
inside location to protect from moisture. Properly ground to conform with all
governing codes and ordinances. Observe all local plumbing codes and drain
restrictions. The system and installation must comply with all state and local
laws and regulations.
NOTE PN 01020620 and PN 01018133 plug-in transformer are rated for indoor
installations only.

Placement
NOTE Read this section entirely before starting the installation. Follow all applicable
plumbing and electrical codes.
Refer to Figure 1 for system placement.
1. With the exception of media containers, open the remaining containers, remove all the compo-
nents, and inspect them before starting installation.
2. Set the media tank on a solid, level surface near water, drain and electrical facilities.
3. Set the brine system on a flat, smooth, solid surface as near the media tank as possible.
Tank Assembly
9” and 10” tanks are filled with media at the factory.
1. Before the unit can be connected to the plumbing, you must insert the manifold and load the
media into the tank for 12” and 14” units.
CAUTION! Do not lay the tank down unless a suitable lifting device
is available. Personal injury and damage to the unit can
result if dropped.
Position the Mineral Tank(s)
Determine the location for the mineral tanks(s) prior to loading, because they will be difficult to move after
the underbedding and gravel are loaded.

Load the Tank (12” and 14” Tanks)
Position the tank so that the Culligan® logo is in the front.
2. Remove the inlet strainer.
3. Install the outlet manifold into the tank (Figure 2).
4. Cover the tops of the manifolds with a clean rag.
5. Using a large-mouth funnel, load the Culligan underbedding
through the top of the tank.
CAUTION! DO NOT allow the outlet manifold
to move when loading the media.
The manifold must remain vertical
to ensure a good seal at the gasket.
Rap the tank near the bottom with a
rubber mallet to level the sand.
6. Load the tank with the Cullex® ion exchange resin. Leveling is not
required.
7. Remove the funnel.
8. Install the inlet strainer making sure to thread the strainer until it
bottoms out on the tank thread. Failure to install the strainer cor-
rectly can cause the control to leak.

Procedure” on page <?>.
Mount the Control Valve
See Figure 4 for an illustration on mounting the control valve to the tank.
1. Assemble the O-rings, located in the parts pack, to the tank adapter.
2. The valve adapter O-ring sits on the first step on the adapter. See Figure 5.
NOTE Do not push the top O-ring down to the flange surface on the adapter.
NOTE The larger of the two O-rings in the parts should be positioned between the
adapter and the valve. Do not stretch the smaller O-ring onto the top of the
tank adapter.
3. Lubricate only the top O-ring on the tank adapter and the outlet manifold o-ring with silicone lubri-
cant.
4. Screw the adapter into the tank until the adapter bottoms out on the tank flange.
NOTE The adapter only needs to be tightened hand-tight to the tank flange.
5. Align the manifold with the center opening in the valve, and firmly press the valve onto the adapter.
NOTE Make sure to push the valve straight down onto the manifold. If the valve is
cocked, it may cause the O-ring to slip off the manifold.
