LIMITED WARRANTY  
• Professional Installation Required: Installation requires shutting water off to home, cutting home water supply pipe and  
using a welding torch to add piping and fittings. Specialized tools and skills are required. Not a do-it-yourself type of project.  
Professional installation required!  
IMPORTANT: SECTION 1: BEFORE INSTALLATION  
Congratulations! We believe your purchase of this water softener will prove to be a very wise choice. When properly installed, operated, and maintained, your  
new softener will provide years of dependable service. Before starting the installation please read this manual all the way through for an overview, and then  
follow the installation in proper sequence. Failure to follow instructions will void warranty.  
Inspecting And Handling Your 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 your permanent record.  
Analysis of Your Water:

IMPORTANTT NOTES  
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.  
Softeners are designed to reduce 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, 3MAPPM System is recommended for use on waters containing more than 2 ppm of iron.

Check Your Pumping Rate and Water Pressure:  
Two water system conditions must be checked carefully to avoid unsatisfactory operation or equipment damage:  
1) MINIMUM water pressure required at the water softener inlet is 20 psi (138 kPa). IF WATER PRESSURE IS OVER 80 psi (552 kPa), A PRESSURE RE-  
DUCING VALVE MUST BE INSTALLED IN THE WATER SUPPLY LINE AHEAD OF THE WATER SOFTENER.  
CAUTION  
To reduce the risk associated with property damage due to water leakage:  
Do not install if water pressure exceeds 100 psi. If your water pressure exceeds 80 psi (552 kPa), you must install a pressure limiting valve. Contact a plumb-  
ing professional if you are uncertain how to check your water pressure.  
NOTE: If you have a municipal or a community water 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:  
Water Pressure:  
Low  
psi  
High  
psi  
CAUTION  
To reduce the risk associated with property damage due to water leakage:  
Do not install system where water lines could be subjected to vacuum conditions without appropriate measures for vacuum prevention.  
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.  
2) The pumping rate of your well must be sufficient for satisfactory operation and BACKWASHING of the water softener. (See SPECIFICATIONS AND  
OPERATING DATA, Section 6)  
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 drain.  
3) Locate in correct relationship to other water conditioning equipment (Figure 1, page 2-1).  
4) Locate the softener in the supply line BEFORE the water heater. Temperatures above 110°F (43.3°C) will damage the softener and void the factory  
warranty.  
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 installation for easy servicing.  
7) Provide a non-switched 110V, 60Hz (220V, 50Hz for specified systems) power source for the control valve.  
WARNING  
To reduce the risk associated with ingestion of contaminants:  
Do not use with water that is microbiologically unsafe or of unknown quality without adequate disinfection before or after the system.  
CAUTION  
To reduce the risk associated with property damage due to water leakage:  
Protect from freezing, relieve pressure and drain system when temperatures are expected to drop below 33°F (0.6°C).  
Do not install on hot water supply lines. The maximum operating water temperature of this filter system is 110°F (43.3°C).

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 heating/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 plus the backwashing requirements of the water softener. Consult our Customer Service  
Department at 1-866-990-9785 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.  
CAUTION  
To reduce the risk associated with property damage due to plugged water lines:  
• Pay particular attention to correct orientation of control valve. Water flow should match arrow on control valve. The Inlet and Outlet of other water treatment  
equipment products will vary depending on the control valve brand used.  
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.  
WARNING  
To reduce the risk associated with a hazardous voltage:  
• If the home electrical system requires use of the cold water system as an electrical safety ground, a jumper must be used to ensure a sufficient ground connection  
across the filter installation piping — refer installation to qualified personnel.  
5) Sweep the floor to eliminate objects that could pierce the brine tank.  
IMPORTANT NOTE  
Sodium Information: Water softeners utilizing sodium chloride for regeneration add sodium to the water softened water. Persons who are on sodium re-  
stricted diets should consider the added sodium as part of their overall sodium intake. As a reference as to how much sodium is added to softened water  
consider the following. For each grain per gallon of water hardness that is exchanged from the water supply, 7.5 milligrams per liter of sodium will be added  
to the softened water. e.g. 10 grains per gallon (gpg) exchanged will add 75 milligrams of sodium to the softened water.

SECTION 2: INSTALLATION  
Proper installation sequence of water conditioning equipment is very important. Refer to the following diagram for your particular water supply.  
Figure 1  
CAUTION  
To reduce the risk associated with property damage due to water leakage:  
Read and follow Use instructions before installation and use of this water treatment system.  
Installation and use MUST comply with existing state or local plumbing codes.  
To reduce the risk associated with property damage due to plugged water lines:  
• Pay particular attention to correct orientation of control valve. Water flow should match arrow on control valve. The Inlet and Outlet of other water treatment  
equipment products will vary depending on the control valve brand used.  
Step 1  
(a) Remove control valve by removing quick connect clamp and using a garden hose or bucket, to fill SOFTENER TANK  
with water (this filling method prevents air entrapment that can cause loss of resin during initial regeneration proce-  
dure). Replace control valve. Make sure clamp is reassembled as shown in Figure 2 "LATCH" arrows should point  
toward each other.  
(b) Attach BYPASS VALVE/YOKE ASSEMBLY (Figure 3) using ADAPTER COUPLINGS, CLIPS and SCREWS to CONTROL VALVE  
(Figure 4). On Meter initiated models, attach METER between BYPASS VALVE and CONTROL VALVE (Figure 4).  
Step 2  
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.  
CAUTION  
To reduce the risk associated with property damage due to water leakage:  
SHUT OFF FUEL OR ELECTRIC POWER SUPPLY TO WATER HEATER after water is shut off.  
Figure 2. CLAMP ASSEMBLY  
Step 3  
Cut main supply line as required to fit plumbing INLET and OUTLET of BYPASS VALVE ASSEMBLY.  
Use flexible tubing connections to connect the valve to household plumbing (as shown in sche-  
matic).  
Step 4  
Solder or solvent weld 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 5  
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.  
Some areas prohibit the use of flexible drain lines. Check with local code officials prior to installation.  
Step 6  
Position DRAIN LINE over drain and secure firmly. To prevent backsiphoning of sewer water, provide an air-gap of at least 2 in. or 2 pipe diameters between end  
of drain hose and drain (Figure 5). DO NOT raise DRAIN LINE more than 10 ft. above floor.  
Step 7  
Connect one end of the 3/8 in. poly brine line to BRINE VALVE located on right side of CONTROL VALVE. Connect other end to ELBOW inside of BRINE WELL. Brass  
sleeves and plastic ferrules must be used where necessary. (See Figure 3 and CONTROL VALVE PARTS drawing, Section 6).  
Step 8  
Install OVERFLOW LINE to brine tank OVERFLOW FITTING (Figure 4). Discharge of line must be lower than OVERFLOW FITTING. DO NOT INTERCONNECT OVER-  
FLOW LINE WITH VALVE DRAIN LINE (STEP 6).  
Step 9  
On time clock initiated models, set REGENERATION 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/89 liters), 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).  
The control valve design permits adjustment of the salt dosage. This adjustment may be necessary when unusual operating conditions exist, such as high con-  
centrations 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.  
Step 10  
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 preset 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 lifestyle require regular 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 ex-  
ample, if 1:00 a.m. regeneration is desired and actual time of day is 10:00 a.m., advance 24-HOUR 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.  
Step 11  
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 laundry bleach.  
Step 12  
Put softener through a complete regeneration - to sanitize the system before use (refer to HOW TO SET TIME CLOCK (or METER) REGENERATION CONTROL for  
instructions on manual regeneration.)  
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 HARD-  
NESS (if ADJUSTED HARDNESS is between two numbers in schedule, use higher number). Number in box represents FREQUENCY or NUMBER OF  
times per 12 DAYS timer should be set to regenerate. Refer to HOW TO SET TIME CLOCK REGENERATION CONTROL to set correct frequency.  
EXAMPLE: You have Model NWS100, 4 in family and 20 gpg adjusted hardness. Refer to REGENERATION FREQUENCY SCHEDULE for Model Series 100 and  
locate box intersected by 4 in family and 20 gpg adjusted hardness. The figure "3" in box indicates a REGENERATION frequency of THREE TIMES PER 12  
DAYS (if a "1", "2", "4", etc. were in box, frequencies of once, twice and four times per twelve days, respectively, would be indicated.)

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 GENERATION 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.  
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.  
HOW TO MANUALLY REGENERATE YOUR WATER SOFTENER AT ANY TIME:  
A slight, clockwise movement of the manual regeneration knob engages the program wheel and starts the regeneration process.  
The black center knob will make one revolution in the following approximately three hours and stop in the position shown in the drawing.  
Even though it takes three hours for this center knob to complete one revolution, the regeneration cycle of your unit might be set for only one-third of this time.  
In any event, conditioned water may be drawn after rinse water stops flowing from the water conditioner drain line.  
NOTE: The backside of the timer is set the same as the standard time clock regenerated models.  
* Adjusted hardness equals hardness in grains per gallon (gpg) plus 3 times the iron in parts per million (ppm).

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.  
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.  
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.
