SECTION 1: BEFORE INSTALLATION
Congratulations! We believe your purchase of this water
softener will prove to be a very wise choice. When properly
installed, your new softener will provide many years of
trouble-free service. Before starting the installation we
suggest you read this manual all the way through for an
overview, and then follow the installation steps in the proper
sequence. IMPROPER INSTALLATION could void the
warranty.
INSPECTING AND HANDLING YOUR WATER SOFTENER:
Inspect the equipment for shipping damage. If damaged,
notify the transportation company and request a damage
inspection.
Handle the equipment with care. Damage can result if
dropped or if the brine tank is set on sharp, uneven projections on the floor. When handling, do not turn the water
softener unit upside down.
MAKE SURE YOUR WATER HAS BEEN THOROUGHLY
TESTED:
An analysis of your water should be made prior to the
selection of your water conditioning equipment. Your dealer
will generally perform this service for you, and may send a
sample to the factory for analysis and recommendations.
Enter your analysis below for a permanent record.
NOTE: Hydrogen sulfide (H2S) must be tested for at the well
site. For accuracy, the sample must be drawn with the pump
RUNNING, and the test be completed within ONE minute
after the sample is drawn.
NOTE: Softeners are designed to remove hardness but can
handle reasonable amounts of soluble iron if consideration
is given to content when selecting model and regeneration
settings. To treat sulfur (hydrogen sulfide), bacterial iron,
precipitated iron or very high levels of soluble iron requires
special equipment in addition to a water softener. For best
results, a Chem-Free™ Iron Removal System is recommended for use on waters containing more than 2 ppm of
iron.

CHECK YOUR WATER PRESSURE AND PUMPING
RATE:
Two water system conditions must be checked carefully to
avoid unsatisfactory operation or equipment damage:
5) Do NOT install the softener in a location where freezing
temperatures occur. Freezing may cause permanent
damage and will also void the factory warranty.
6) Allow sufficient space around the unit for easy servicing.
1) MINIMUM water pressure required at the filter tank inlet
is 20 psi. IF PRESSURE IS OVER 100 PSI, A PRESSURE REDUCING VALVE MUST BE INSTALLED IN
THE WATER SUPPLY LINE AHEAD OF THE WATER
SOFTENER.
NOTE:
supply and daytime water pressure is 85 psi or more,
nighttime pressure may exceed 100 psi. Call your local
water department or plant operator to obtain pressure
readings. If you have a private well, the gauge on the
pressure tank will indicate the high and low system
pressure. Record your water pressure data below:
IMPORTANT: Damage to system can occur (including
possible mineral tank structural failure resulting in a water
leak) if system is subjected to a vacuum. The installer should
take appropriate measures if there is the possibility a vacuum
may occur. This would include the installation of an appropriate device in the supply line to the system, i.e., a vacuum
breaker or backflow prevention device. Vacuum damage
voids the factory warranty.
If you have a municipal or a community water
WATER PRESSURE
Low _______ psi High _______ psi
7) Provide a non-switched 110/120V, 60Hz power source
for the control.
FACTS TO REMEMBER WHILE PLANNING YOUR INSTALLATION:
(1) All installation procedures MUST conform to local and
state plumbing codes.
(2 ) If lawn sprinkling, a swimming pool, or geothermal heat-
ing/cooling or water for other devices/activities are to be
treated by the water softener, a larger model MUST be
selected to accommodate the higher flow rate and softening demand of these items. The pumping rate of the
well pump must be sufficient to accomodate these items
plus the backwashing requirements of the water softener.
Consult your dealer for alternative instructions if the
pumping rate is insufficient.
(3) Remember that the water softener INLET is attached to
the pipe that supplies water (i.e., runs to the pump), and
the OUTLET is the line that runs toward the water
heater.
(4) Before commencing the installation it is advisable to
study the existing piping system and to determine the
size, number and type of fittings required.
2) The pumping rate of your well pump must be sufficient
for satisfactory operation and BACKWASHING of the
WATER SOFTENER. (see SPECIFICATIONS AND
OPERATING DATA , Section 5)
LOCATE WATER CONDITIONING EQUIPMENT CORRECTLY:
Select the location of your water softener with care. Various
conditions which contribute to proper location are as follows:
1) Locate as close as possible to water supply source.
2) Locate as close as possible to a floor or laundry tub
drain.
3) Locate in correct relationship to other water conditioning
equipment (Figure 1).
4) Locate the softener in the supply line BEFORE the
water heater. Temperatures above 100°F (38°C) will
damage the softener and void the factory warranty.
NOTE: If the plumbing system is used as the ground leg
of the electrical supply, continuity should be maintained
by installing ground straps around any nonconductive
plastic piping used in installation.
(5) It is also advisable to sweep the floor to eliminate objects
that could pierce the brine tank.
(6) SODIUM INFORMATION: Water softeners using so-
dium chloride for regeneration add sodium to the water.
Persons who are on sodium restricted diets should
consider the added as part of their overall sodium
intake.

SECTION 2: INSTALLATION
Figure 1. INSTALLATION SCHEMATIC
Step 1. If not factory pre-installed, attach BYPASS VALVE
or YOKE ASSEMBLY using ADAPTER COUPLINGS, CLIPS and SCREWS to CONTROL
VALVE (Figure 2). On meter initiated models,
attach METER between BYPASS VALVE and
CONTROL VALVE (Figure 2).
Step 2. On Series 2501 ONLY attach salt grid leg exten-
sions (provided) to bottom of salt grid legs by
snapping nipple on end of extension into hole in
the bottom of the grid leg. NOTE: Extension legs
should be installed whenever salt dosage on any
model softener is 15 lbs. or more. Verify all
packing materials have been removed from the
brine tank. On all units, push salt grid down into
brine tank until grid legs rest on bottom of brine
tank.
Step 3. Shut off all water at main supply valve. On a private
well system, turn off power to pump and drain
pressure tank. Make certain pressure is relieved
from complete system by opening nearest faucet to
drain system. SHUT OFF FUEL SUPPLY TO
WATER HEATER.
Step 4. Cut main supply line as required to fit plumbing to
INLET and OUTLET of unit.
Step 5. Attach plumbing. DO NOT apply heat to any fitting
connected to BYPASS or CONTROL VALVE as
damage may result to internal parts or connecting
adapters. MAKE CERTAIN WATER FLOW ENTERS THROUGH INLET AND DISCHARGES
THROUGH OUTLET.

Step 6. Attach DRAIN LINE to DRAIN LINE FITTING. To
prevent back pressure from reducing flow rate
below minimum required for backwash, DRAIN
LINE MUST be sized according to run length and
relative height. Be careful not to bend flexible drain
tubing sharply enough to cause "kinking" (if kinking
occurs DRAIN LINE MUST BE REPLACED). Typical examples of proper DRAIN LINE diameters are:
(1) 1/2 in. ID up to 15 ft. when discharge is lower
than INLET.
(2) 5/8 in. ID up to 15 ft. when discharge is slightly
higher than INLET.
(3) 3/4 in. ID when drain is 25 ft. away and/or drain
is installed overhead.
Figure 3. TYPICAL DRAIN
Step 7. Position DRAIN LINE over drain and secure firmly.
To prevent backsiphoning of waste water, provide
an air gap of at least 2 in. or 2 pipe diameters
between end of drain hose and drain (Figure 3). DO
NOT raise DRAIN LINE more than 10 ft. above floor.
Step 8. Connect one end of the 3/8 in. poly line to BRINE
VALVE located on the right side of CONTROL
VALVE. Connect other end to ELBOW inside of
BRINE WELL. Brass insert sleeves and plastic
ferrules must be used where necessary. (Figure 2
and CONTROL VALVE PARTS Drawing, Section
6).
Step 9. Install OVERFLOW LINE to brine tank OVERFLOW
FITTING (Figure 2). Discharge of line must be lower
than OVERFLOW FITTING. DO NOT INTERCONNECT OVERFLOW LINE WITH VALVE DRAIN
LINE.
Step 10. Make certain BYPASS VALVE INLET and OUT-
LET KNOBS ARE IN "BYPASS" position. After all
plumbing connections have been completed, open
main water shut-off valve or restore power to well
pump. Check for leaks and correct as necessary.
Figure 4. BYPASS VALVE
Step 11. Manually stage control to BACKWASH POSI-
TION by turning "MANUAL REGENERATION
KNOB", clockwise to "BACKWASH" position, refer to HOW TO SET TIME CLOCK REGENERATION CONTROL (Section 3).
Step 12. Partially open INLET valve in plumbing or on
BYPASS VALVE (Figure 4). This will allow the
unit to fill slowly from the bottom up, eliminating air
entrapment. Allow unit to fill slowly, failure to do
so could result in loss of resin to the drain. Once
a steady stream of water, no air, is flowing to drain,
the INLET VALVE can be fully opened. The
OUTLET valve can also be opened and the BYPASS (if applicable) can be closed. Manually
advance control to SERVICE POSITION. Plug
into a non-switched 110/120V, 60Hz power source.
Step 13. On time clock initiated models, set REGENERA-
TION FREQUENCY. Refer to REGENERATION
FREQUENCY SCHEDULES (Section 3) to determine correct frequency, then refer to HOW TO
SET TIME CLOCK REGENERATION CONTROL
(Section 3) for instructions on setting frequency.
For meter initiated models, refer to HOW TO SET
METER REGENERATION CONTROL.
NOTE: Regeneration settings for both time clock
and meter initiated models are factory preset for
the most efficient salt use and minimum water
consumption used for regeneration (as little as 50
gallons), and conform to the INDUSTRY SALT
EFFICIENCY STANDARDS (required by some
states). REGENERATION FREQUENCY
SCHEDULES are designed for use with factory
regeneration settings (listed in SPECIFICATIONS
AND OPERATING DATA, Section 5).
2-2
The control valve design permits adjustment of
the salt dosage. This adjustment may be necessary when unusual operating conditions exist,
such as high concentrations of iron or hardness
and/or high flow rates or daily water consumption.
This adjustment is easily performed by loosening
the screw holding the white cam (on backside of
timer) and adjusting the pointer to the desired
pounds of salt.
NOTE: For salt dosages greater than 15 lbs, grid
leg extensions must be attached to bottom of grid
legs. For salt dosages less than 15 lbs. DO NOT
use extension legs.
Step 14. Set TIME OF DAY (refer to appropriate HOW TO
SET TIME CLOCK/METER REGENERATION
CONTROL, Section 3). When shifting to daylight
saving time (and back), you may wish to adjust
TIME OF DAY accordingly.
NOTE: TIME OF REGENERATION is pre-set for
2:00 a.m. because at this time water consumption
is generally minimal (a built-in hard water bypass
does, however, permit water to be drawn during
regeneration). Should your life style require regu-
lar use of water during the 2:00 to 3:00 a.m.
regeneration period, or if other water treatment
equipment is also set for 2:00 a.m. regeneration,
the TIME OF REGENERATION will need changing. To change, adjust time of day on 24-HOUR
GEAR ahead or behind actual time of day. For
example, if 1:00 a.m. regeneration is desired and
actual time of day is 10:00 a.m., advance 24HOUR GEAR one hour to 11:00 a.m.; or, should
3:00 a.m. regeneration be desired, set gear back
one hour to 9:00 a.m.
SPECIAL SERVICE INSTRUCTIONS:
Under normal circumstances removal of valve should never
be required. However, if it must be removed, it can be done
by disassembling the quick release clamp, by removing
latch. Pressure should be relieved before attempting any
disassembly. Upon reassembly, all o-rings should be
lubricated with silicone grease. Reassemble clamp as
shown in Figure 5. MAKE SURE ARROWS ON LATCH
SIDE OF CLAMP ARE ALIGNED.
Figure 5. CLAMP ASSEMBLY
Step 15. Before loading salt, using a pail or garden hose,
add approximately 3 gals. water to brine tank (6
gals. for units with extended grid legs). Then add
initial salt fill to brine tank, and one cup full of
unscented laundry bleach to brine well.
Step 16. Put softener through complete regeneration to
sanitize the system before use (Refer to HOW TO
SET TIME CLOCK (or METER) REGENERATION CONTROL for instructions on manual regeneration). RESTORE FUEL SUPPLY OR
POWER TO WATER HEATER.
Installation is now complete, and your water softener is now
ready for service!

SECTION 3: REGENERATION INSTRUCTIONS
INSTRUCTIONS FOR USING REGENERATION FREQUENCY SCHEDULES:
(Time Clock Initiated Models Only)
(1) Determine ADJUSTED HARDNESS by adding three (3)
times the iron content in parts per million (ppm) to the
hardness in grains per gallon (gpg). The resulting
number is ADJUSTED HARDNESS.
EXAMPLE: Hardness is 14 gpg and iron is 2 ppm.
ADJUSTED HARDNESS is 20 gpg (14 plus 3 times 2).
(2) Select REGENERATION FREQUENCY SCHEDULE
corresponding to your model. Locate box intersected by
NUMBER IN FAMILY and ADJUSTED HARDNESS (if

HO W T O SET TIME CLOCK REGENERA TION CONTROL
HOW TO SET DAYS ON WHICH WATER SOFTENER IS
TO REGENERATE:
Rotate the skipper wheel until the number "1" is at the red
pointer. Set the days that regeneration is to occur by sliding
tabs on the skipper wheel outward to expose trip fingers.
Each tab is one day. Finger at red pointer is tonight. Moving
clockwise from the red pointer, extend or retract fingers to
obtain the desired regeneration schedule.
HOW TO SET THE TIME OF DAY:
(1) Press and hold the red button in to disengage the drive
gear.
(2) Turn the large gear until the actual time of day is
opposite the time of day pointer.
(3) Release the red button to again engage the drive gear.
(4) Time of regeneration is preset for 2:00 a.m.
HOW TO MANUALLY REGENERATE YOUR WATER
SOFTENER AT ANY TIME.
Turn the manual regeneration knob clockwise.
A slight, clockwise movement of the manual regeneration
knob engages the program wheel and starts the regeneration program.
The black center knob will make one revolution in the
following approximately three hours and stop in the position
shown in the drawing (SERVICE POSITION).
Even though it takes three hours for this center knob to
complete one revolution, the regeneration cycle of your unit
might be set only one-third of this time.
In any event, conditioned water may be drawn after rinse
water stops flowing from the water softener drain line.

HOW TO SET METER REGENERATION CONTROL
TYPICAL RESIDENTIAL APPLICATION:
To program, just set the time, set the hardness and it
automatically monitors system needs and regenerates only
when necessary. To set time of day, press red time set
button and turn 24-hour gear until present time of day is
opposite "time of day arrow." Set program wheel by lifting
the "people" dial and rotating it so that the number of people
in the household is aligned with the grains per gallon water
hardness (adjusted hardness*) scale. Release the dial and
check for firm engagement at setting. (This method will
provide reserve capacity of one day's supply based on 75
gallons per person.)
OPTIONAL PROGRAMMING PROCEDURE:
Calculate the gallon capacity of the system, subtract the
necessary one day's reserve requirement and set the gallons available opposite the small white dot on the program
wheel gear. Note: drawing shows 850 gallon setting. The
capacity (gallons) arrow denotes remaining gallons exclusive of fixed reserve.
HOW TO SET THE TIME OF DAY:
(1) Press and hold the red button in to disengage the drive
gear.
(3) Release the red button to again engage the drive gear.

SECTION 7: MAINTENANCE
REPLENISHMENT OF SALT SUPPLY:
The salt storage capacity of the brine tank is approximately
160 lbs. During each regeneration a specific amount of salt
is consumed, thus requiring its periodic replenishment (the
frequency is dependent on the regeneration schedule).
Always replenish salt before the supply is exhausted to
assure a continuous supply of softened water.
TYPE OF SALT TO USE:
Any type of water softener salt may be used. There are
advantages and disadvantages to every type of salt. Please
ask your local dealer for his advice. Your unit is designed to
compensate for the disadvantages.
BRINE TANK CLEAN-OUT:
To prevent service problems the brine tank should be
emptied and flushed out with a garden hose when dirt and
other insolubles accumulate. The clean-out frequency depends on the type salt used and regeneration frequency.
The clean-out should be done when the salt level is low.
Steps to follow:
(1) Disconnect brine line at either end.
(2) Turn brine tank upside down and discard old
salt.
PREVENTING IRON-FOULING OF MINERAL BED:
If iron is present in the water supply, the softener mineral bed
will eventually become iron-fouled, resulting in reduced
softening capacity and rust-stained fixtures. Mixing one to
two ounces of IRON-X™ Mineral Cleaner with every 80 lbs.
of salt added to brine tank will minimize these problems from
occurring. IRON-X™ is available from your dealer.
PERIODICALLY CHECK TIME OF DAY SETTING:
Power outages will cause TIME OF DAY timer setting to
become incorrect. To reset, refer to appropriate HOW TO
SET TIME CLOCK (or METER) REGENERATION CONTROL, Section 3.
MALFUNCTION OF UNIT:
Your water softener, under normal conditions, should provide years of trouble-free service; however, since it is a
mechanical device, it can malfunction. (Refer to Section 4,
SERVICE INSTRUCTIONS, if necessary).
CHANGE OF OPERATING CONDITIONS:
Should your family size, your water usage habits, or your
water quality change, the regeneration program settings
may have to be adjusted. Consult your dealer if any of the
above occur.
(3) Rinse out with a garden hose.
(4) Reconnect brine line.
(5) Add about 3 gals. of water (6 gals. for units with
extended grid legs) to brine tank before adding
new salt. Perform approximately once a year if
rock salt is used; with other types of salt, approximately once every other year.
