APPLICATION
Water quality - Verify that raw water hardness and iron are
within limits. Note the hardness for setting the salt dosage
and recharge frequency.
Pressure - If pressure exceeds 125 psi (860 kPa), install a
pressure reducing valve (see materials checklist). On private
water systems, make sure the minimum pressure (the pres-
sure at which the pump starts) is greater than 20 psi
(140 kPa). Adjust the pressure switch if necessary.
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.

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 the
Drain Line Chart, Table 1 (page ---), for maximum drain line
length.
NOTICE: Most codes require an anti-siphon device or airgap.
Electrical facilities - A 6-foot grounded cord is provided.
The customer should provide a 3-prong grounded receptacle,
preferably one not controlled by a switch that can be turned
off accidentally. Observe local electrical codes.
WARNING! ELECTRICAL SHOCK HAZARD! DO
NOT REMOVE THE GROUNDING PRONG! IF THE
RECEPTACLE IS DESIGNED ONLY FOR 2-PRONG
PLUGS, OBTAIN A 3-PRONG ADAPTER AND
GROUND IT SECURELY TO THE RECEPTACLE. DO
NOT USE EXTENSION CORDS.

SETTINGS / 9
Settings
Before the unit can be recharged and put into service, several
settings must be made.
BACKWASH
Backwash, the first step in the recharge cycle, expands and
loosens the resin bed, and flushes away accumulated turbid-
ity. The backwash interval is preset at the factory for 10
minutes which is adequate for most water supplies. It is
adjustable, however, for 5 to 30 minutes. It is recommended
that backwash last just long enough so that the effluent from
the drain line is clear. Backwash too long and water is wasted,
not long enough and the tank becomes fouled with sediment.
If backwash time adjustment is needed, see Fig. 17. THE
TIMER MUST BE DISCONNECTED FROM THE POWER
SUPPLY WHEN MAKING INTERNAL ADJUSTMENTS.
1. Remove the timer from the case and turn it over to view
the fiber electrical barrier.
2. Loosen both the screw holding the barrier in place and
rotate the barrier to expose the cams and switches.
3. Refer to Fig. 7. Loosen screw (A) and rotate the black
cam segment (B) until its pointer indicates the desired
backwash time on the grey cam segment (C). Retighten
screw (A).
4. Replace the fiber barrier and tighten the screws.
All normal adjustments from this point on may be made with
the timer mechanism securely fastened within its case. The
unit may be plugged in at this time.
TIME OF RECHARGE
The timer is factory-set to recharge at 2:00 a.m. (plus or
minus 20 minutes), a timer when water usage is at a mini-
mum for most families. If water is used during recharge,
hard water will be automatically bypassed to service. If it
would be more convenient to have the water conditioner
recharge at a different time of day the setting may be changed
as follows, referring to Fig. 8.
1. The position of the time-of-day dial (E) in relation to the
peg (D) on the black tab determines when the conditioner
will begin to recharge.
2. Remove the set screw (M).
3. Lift the white time-of-day dial and rotate it until the
desired time of recharge is opposite the peg (D). Please
note that whenever the time of recharge is changed, the
time-of-day setting must be changed also.
4. Replace set screen.
FIG. 7

10 / CULLIGAN®MARK 10 AUTOMATIC WATER CONDITIONER
FIG. 8
TIME OF DAY
Upon completing the installation, the timer must be set to
the correct time of day. Time of day must also be reset after
any kind of power interruption, such as that caused by an
electrical storm. See Fig. 8.
1. Determine the correct time of day.
2. Grasp the gear (F) and lift straight up (the white time-of-
day dial will lift with it). Rotate the dial until the correct
time of day lines up with the pointer (G). The dial is spring-
loaded and will return to its position when released. Make
sure the teeth mesh.
Note that the silver half of the time-of-day dial designates
the daytime hours, while the black half designates the night-
time hours.
SERVICE POSITION
The timer assembly is in the service position when the tooth-
less notch in the cam gear (J) is over the teeth on the idler
gear (H). The timer will return to this position after each
recharge (Fig. 8).
SALT DOSAGE/RECHARGE FREQUENCY
(Time Clock Models Only)
The salt dosage is the number of pounds of salt the softener
will use with each recharge. The frequency is the number of
recharges per six day period (or seven day period, with
optional 7-day frequency wheel).
To determine the salt dosage and frequency, two things must
be known:
1. Daily water usage as determined by the number of
persons in the household or by actual gallonage measure-
ments.
2. The total hardness of the water as shown on the Culligan
Water Analysis Report.
With these factors known, refer to Salt Dosage/Frequency
Charts, Table 2A/2B. Find the box in the right or left column
with the number of individuals in the household, or the ap-
proximate daily average water usage. Move across until the
box under the correct hardness range is reached. The number
in the shaded portion of the box indicates the amount of salt,
in pounds (kilograms), to be used for each recharge, and the
number in the non-shaded portion indicates the number or
recharges required per six-day period.
NOTICE: The optional 7-day frequency wheel may be used
when recharge is desired only on specific days of the week.
As an example, if four individuals live in the household, and
the water has a total hardness of 18 grains per gallon, the salt
dosage per recharge for the water conditioner will be 5 pounds
(2.5 kg) and the recharge frequency will be 3 (or every 2
days). Monthly salt usage can be estimated, using these
figures, at about 75 pounds (37.5 kg).
SALT DOSAGE SETTING
Set the salt dosage as follows, referring to Fig. 9.
1. Loosen screw (I).
2. Grasp the gear (L) and rotate the salt dosage dial until the
desired dosage is indicated by the point (K).
3. Retighten screw (I).
FREQUENCY (Time Clock Models Only)
Starting with all pins in the up position, set the correct fre-
quency on the frequency wheel by pushing down the appro-
priate number of pins. Refer to Tables 5A and 5B.
FIG. 9

1. Rotate the frequency wheel (O) until the pin beneath the
number 1 is opposite the peg on the manual recharge
lever (N).
2. Refer to Table 3 and push down the pins under the
numbers indicated.
If using the optional 7-day frequency wheel, assign a num-
ber to each day of the week. For example, 1-Sunday, 2-Mon-
day, 3-Tuesday, and so on. Line up the number correspond-
ing to the present day of the week and push down only those
pins corresponding to the days upon which you want the unit
to recharge. All remaining pins must be in the up position.
GALLONS SETTING (Soft-Minder®Models Only)
Determine the daily water use for the household. Usually
75-100 gallons per day per person is adequate. Using Tables
2A and 2B, locate the hardness range for your water supply.
Move down the column and locate the gallons setting and
salt dosage which best suits the application. Usually two to
three days between regenerations yields the best results. Al-
low for one half to one days water usage as reserve capac-
ity. Set the salt dosage per the instructions on page 10.
The gallons are set with the dip switches located on the board.
Refer to Table 4 for the proper positioning of the switches.
Dip switch number 1 should be set to the R (run) position.

TABLE 4 - REGENERATION SCHEDULE
EXTRA RECHARGE
An extra recharge may be initiated at any time by moving the
manual recharge lever (F) fully to the left, then release. On
Aqua-Sensor®models, the demand button, must also be de-
pressed momentarily. The timer will complete the cycle au-
tomatically and, on timeclock models, recharge again the next
regularly scheduled recharge time. Sensor models will not
recharge again until the sensor detects the need. An extra
recharge should not be initiated 2 to 3 hours before a sched-
uled recharge is to take place.

14 / CULLIGAN®MARK 10 AUTOMATIC WATER CONDITIONER
Start-Up Procedure
NOTICE: A sanitizing agent has been added to the condi-
tioner tank at the factory. This sanitizing agent must be flushed
out before the unit is placed into service by initiating a
recharge using the steps outlined below.
1. With the timer in the service position, connect the three-
wire power cord to an appropriate grounded electrical
outlet. If a three-wire outlet is not available, purchase a
“three-prong to two-prong adapter” from your local hard-
ware store. The ground wire from the adapter should be
affixed to the outlet box or plate.
2. Set the timer to the correct time of day, time of recharge,
frequency of recharge, and refill regulator assembly to
the proper number.
3. With the unit in the service position, slowly open the
inlet valve or slowly push the blue knob of the
Cul-Flo-Valv®bypass. Allow water to fill the tank.
4. Turn the water off. Rotate the cam with the salt dosage
dial one third turn. Slowly open the valve. For units
equipped with the Soft-Minder®meter, push the red
button on the timer mechanism.
5. Rotate the salt dosage cam until the notch in the gear is
over the idler gear (see page 10, Service Position). A
manual regeneration should be initiated at this time.
6. To allow the customer to enjoy the benefits of soft water
at this time, it is advisable to drain the hot water tank of
the hard water and allow it to be refilled with soft water.
Otherwise, because of the capacity of the hot water tank,
it may take two or three days to displace the hard water
with soft water in the hot water tank.
7. Explain to the customer the operation of the bypass
valve(s) and make sure that the customer knows that there
will be new sounds associated with the recharging and
operating of the unit.
8. Advise the customer to periodically check and replenish
the salt supply.
9. Clean up the unit and the installation site, removing any
soldering or pipe threading residues from the equipment
with a damp towel.

SANITIZING PROCEDURE / 15
Sanitizing Procedure
CHEMICAL OR OTHER COMPOUNDS CONTAINING
SODIUM HYDROSULFITE OR SODIUM BISULFITE,
OR ANY OTHER REDUCING AGENT, DISCONNECT
THE DEVICE AND MANUALLY REGENERATE THE
UNIT BEFORE SANITIZING.
• DO NOT USE THIS PROCEDURE IF THE SOFT-
ENER SALT CONTAINS IRON CONTROL ADDI-
TIVES.
1. Remove the brine tank cover and the small cover on the
brine valve chamber.
2. Pour directly into the brine chamber 1 cup (9-inch units)
or 2 cups (12-inch units) of common household bleach
(5-1/4% sodium hypochlorite).
3. Manually start recharge. Allow the unit to complete the
recharge cycle automatically.
If tastes and odors return frequently, even after sanitization,
a continuous chlorination system may be needed. Contact
Household Application Engineering for assistance. Also, have
the consumer send a sample to a qualified laboratory for
bacterial analysis.
A water softener in daily use on a potable water supply gen-
erally requires no special attention other than keeping the
salt tank filled. Occasionally, however, a unit may require
sanitation under one of the following conditions:
• The unit has stood idle for a week or more (the premises
vacant or the residents on vacation).
• On private supplies, the appearance of off-tastes and odors,
particularly if musty or “rotten egg” (caused by harmless
sulfate-reducing bacteria).
For occasional occurrences, the softener can be sanitized with
household bleach as follows:
NOTICE: If the water supply contains iron, regenerate the
softener before sanitizing to remove accumulated iron from
the Cullex®resin.
WARNING! HAZARD FROM TOXIC FUMES!
CHLORINE BLEACH AND COMMON IRON CON-
TROL CHEMICALS MAY GENERATE TOXIC FUMES
WHEN MIXED.
• IF THE UNIT USES CULLIGAN®SOFNER-GARD™
