should flash all wording, then flash the software version (e.g.  
154) and then reset the valve to the service position.  
All plumbing should be done in accordance with local plumb-  
ing codes. The pipe size for the drain line should be a mini-  
mum of 1/2". Backwash flow rates in excess of 7 gpm or  
length in excess of 20' require 3/4" drain line.  
Do not use Vaseline, oils, other hydrocarbon lubricants or  
spray silicone anywhere. A silicon lubricant may be used on  
black o-rings but is not necessary. Avoid any type of lubri-  
cants, including silicone, on red or clear lip seals.  
Solder joints near the drain must be done prior to connect-  
ing the drain line flow control fitting. Leave at least 6"  
between the drain line control fitting and solder joints when  
soldering pipes that are connected on the drain line control  
fitting. Failure to do this could cause interior damage to the  
drain line flow control fitting.  
The nuts and caps are designed to be unscrewed or tight-  
ened by hand or with the special plastic wrench. If necessary  
a pliers can be used to unscrew the nut or cap. Do not use  
a pipe wrench to tighten or loosen nuts or caps. Do not place  
screwdriver in slots on caps and/or tap with a hammer.  
When assembling the installation fittings package (inlet and  
outlet), connect the fitting, to the plumbing system first and  
then attach the nut, split ring and o-ring. Heat from soldering  
or solvent cements may damage the nut, split ring or o-ring.  
Solder joints should be cool and solvent cements should be  
set before installing the nut, split ring, and o-ring. Avoid get-  
ting primer and solvent cement on any part of the o-rings,  
split rings, bypass valve or control valve.  
Do not use pipe dope or other sealants on threads, Teflon  
tape must be used on the threads of the 1" NPT elbow or the  
1/4" NPT connection and on the threads for the drain line  
connection. Teflon tape is not necessary on the nut connec-  
tion or caps because of o-ring seals.  
After completing any valve maintenance involving the drive  
assembly or the drive cap assembly and pistons, press the  
NEXT and REGEN buttons for 3 seconds or unplug power  
source jack from the printed circuit board (black wire) and  
plug back in. This resets the electronics  
Plug into an electrical outlet. Note: All electrical connections  
must be connected according to local codes. (Be certain the  
outlet is uninterrupted.)  
Install grounding strap on metal pipes.  
Principles of Softening and Ion-Exchange  
Softening of water by the exchange process involves the  
exchange or substitution of the hardness minerals, chiefly calci-  
um and magnesium, for sodium minerals. The exchange is made  
possible because the minerals are ionic in nature (often called  
ionized impurities) which means they have an electrical charge.  
The ion exchange process is based on the fact that like charges  
repel one another, and unlike charges attract.  
As the calcium and magnesium contact the resin beads in their  
travel through the resin tank, they displace the sodium ions from  
the exchange sites. During the ion exchange process, relatively  
small amounts of other strongly charged cations such as iron  
and manganese are also removed along with the calcium and  
magnesium.  
Ion exchange is possible for two reasons: (1) All cations do not  
have the same strength of positive charge and (2) the resin  
prefers the stronger charged cations calcium and magnesium  
than it does the weaker sodium cations.  
Calcium and magnesium ions in water are actually dissolved  
rock. They have been dissolved by water, the “universal solvent”,  
as it trickles down through strata of rock and soil it dissolves cal-  
cium and magnesium deposits. This dissolved rock eventually  
finds its way into an underground aquifer and when water from  
the aquifer is pumped to the surface, it contains the dissolve  
hardness minerals of calcium and magnesium and is said to be  
hard water.  
The exchanged sodium cations pass downward through the  
resin “bed” and out the softener outlet, thus, the softener delivers  
“soft”water.  
Eventually, all of the resin exchange sites are occupied by calci-  
um and magnesium and no further exchange can take place.The  
resin is said to be exhausted and must be regenerated.  
An ion exchange softener exchanges the hardness minerals, cal-  
cium, and magnesium, for sodium, from the softener resin.  
Sodium is less objectionable because it does not build up on sur-  
faces as scale deposits.  
The softener resin is regenerated with a dilute brine solution of  
sodium chloride (common salt) and water. During regeneration  
the flow of service water from the softener is first stopped. Brine  
is drawn from the brine tank mixing with a separate stream of  
water. The brine solution flows through the resin, contacting the  
resin beads loaded with calcium and magnesium ions. Even  
though the calcium and magnesium are more strongly charged  
than the sodium, the concentrated brine solution contains  
literally billions of weaker charged sodium ions which have the  
power to displace the smaller number of calcium and magnesium  
ions. When the calcium and magnesium ions are displaced, the  
positive sodium ions are attracted to the negative exchange sites  
is said to be regenerated and ready for the next softening cycle.  
All three minerals are positively charged ions called cations. The  
exchange takes place by passing water containing hardness  
minerals over a man-made ion exchange resin contained in a  
suitable tank. The resin, polystyrene divinyl benzene in most-  
modern softeners, consist of millions of tiny plastic beads, all of  
which contain many negatively charged exchange sites to attract  
the positive cations. When the resin is in the regenerated state  
these negatively charged exchange sites hold positively charged  
sodium cations.

CONTROL VALVE FUNCTIONS  
Control Valve Function and Cycles of Operation  
This glass filled Noryl fully automatic control valve is designed  
The transformer power pack comes with a 15-foot power cord  
and is designed for use with the control valve. The transformer  
power pack is for dry location use only. The control valve remem-  
bers all settings for two hours if the power goes out. After two  
hours the only item that needs to be reset is the time of day, all  
other values are permanently stored in the nonvolatile memory.  
The control valve does not need batteries.  
as the primary control center to direct and regulate all cycles of  
a water softener. The control valve can be set to regenerate on  
demand (consumption of a predetermined amount of water)  
and/or as a time clock (passage of a particular number of days).  
The control valve is compatible with a variety of regenerants  
andresin cleaners. The control valve is capable of routing the  
flow, of water in the necessary paths to regenerate or backwash  
water treatment systems. The injector regulates the flow of brine  
or other regenerants. The control valve regulates the flow rates  
for backwashing rinsing and the replenishing of treated water into  
a regenerant tank.  
When the control valve is used as a down flow softener, two  
backwashes always occur. The softener will start regenerant  
prefill before regeneration, the prefill starts two hours before the  
regeneration time set. During the 2-hour period in which the brine  
is being made, treated (softened) water is still available. For  
example:regeneration time = 2:00 am, prefill option selected,  
downflow softener. Fill occurs at 12:00 a.m., start of backwash  
cycle occurs at 2:00 a.m.  
The control valve is designed to deliver high service (27 gpm @  
15 psig) and backwash (27 gpm @ 25 psig) flow rates when the  
bypass has straight fittings. The control valve uses no traditional  
fasteners (e.g. screws), instead clips, threaded caps and nuts  
and snap type latches are used. Caps and nuts only need to be  
firmly hand tightened because radial seals are used. Tools  
required to service the valve include one small blade screwdriv-  
er, one large blade screwdriver, pliers and a pair of hands. A  
plastic wrench is available which eliminates the need for screw-  
drivers and pliers. Disassembly for servicing takes much less  
time than comparable products currently on the market.  
The softener will adjust the backwash and rinse cycles automat-  
ically when the salt dosage is changed . Backwashes can  
be set to be NORMAL or LONGER. The option selected will  
apply to all backwashes. Tables 4 and 5 show the length of the  
cycles when the valve is set up as a softener.  
REGENERATION STEPS AND PURPOSE:  
EXCHANGE CAPACITY DATA  
Brine fill – Brine tank is filled to dissolve salt for next  
regeneration.  
20,000 grain approx. per cu. Ft.  
6 lbs. salt-sodium chloride  
Backwash – Flow through the resin bed is reversed.  
Water flows upward expanding and agitating the resin bed.  
25,000 grain approx. per cu. Ft.  
8 lbs. salt-sodium chloride  
Brine in – Brine is educted from the brine tank and pass-  
es through the resin bed in a downward flow, thus remov-  
ing calcium and magnesium that has accumulated on the  
resin beads and is flush to drain.  
30,000 grain approx. per cu. Ft.  
15 lbs. salt-sodium chloride  
Note: To convert parts per million (PPM) or milligrams per  
liter (mpl) to grains divide by 17.1  
Backwash – A second backwash is performed  
Example: Water hardness of 250 PPM  
Rinse – The resin is now flushed downward at a set  
flow rate. This resettles the bed and rinses out any  
remaining brine left in the resin bed.  
(250 PPM divided by 17.1 PPM/gr.) equals 14.6 gr.  
It is recommended that a good grade of solar or pellet salt  
be used.  
One-gallon water will dissolve approximately 3.0 lbs. of salt  
One gallon of saturated brine weighs 10.74 lbs.  
Service – Softener goes back into service and ready to  
soften water.

waterheater to protect against hot water back-up.  
Note: If there is obvious damage to any equipment, it should  
be noted on the carrier’s Bill Of Lading. Open and inspect the  
contents of all closed crates, cartons, etc. and inspect for con-  
cealed damage. The manufacturer is not liable for any dam-  
age during transit.  
Warning: When piping with copper, solder all piping as sub-  
assemblies before installing. Internal damage can result from  
the high heat of the torch.  
It is recommended that manual isolating valves be installed  
on the inlet and outlet piping along with a system bypass  
valve. This will isolate the unit when service is required.  
Run drain line to a sump, drain trench, or other open drain.  
Open drains are required for taking samples and allowing a  
visual check. Avoid overhead pipe runs to drain facility, as  
undue backpressure will affect the operation of injectors.  
Position the equipment in its proper location, setting on a flat  
surface. Level equipment as required. Equipment out of  
plumb can exhibit poor flow characteristics, which will affect  
the performance of the system.  
Note: Units are shipped with media (resin & gravel), distribu-  
tions tube, and control valve installed. Double-check the valve  
installation on the tank. Tighten if necessary.  
Note: All piping is to meet your local and state code. AVOID  
CROSS CONNECTIONS!  
Unit should be positioned with the valve control facing forward.  
Position brine tank approximately 6" from the softener tank on  
a smooth surface.  
Check the main line water pressure. The softener is designed  
for a minimum of 20 psi and a maximum of 125 psi working  
pressure. If the line pressure exceeds this limit, a pressure-  
reducing valve should be installed.  
Connect the brine air check assembly in the salt/brine tank to  
the brine suction (eductor) connection. If brine tank is located  
more than 6 feet from softener tank, use one size larger tub-  
ing. Tubing 5/8" should be installed from the brine tank over-  
flow to drain. This is a gravity drain designed to divert brine to  
the drain in the event of a malfunction, which would cause  
overflow of the brine tank.  
Maximum allowable water temperature is 40°F (4°C) – 110°F  
(38°C). A 120vac 60 cycle electrical source must be available  
for operation of the controller.  
Connect raw water supply line to the inlet valve connection.  
Connect treated water outlet to service line. It is suggested that the  
pipe size be equal or one size larger than the valve connection.  
Be sure inlet/outlet isolating valves are closed and bypass  
valve is open.  
Installation  
STEP 1: Select Location  
STEP 2: Install a bypass  
Locate main water supply for all faucets and appliances in  
home (if possible outside faucets should be separate so not  
to waste soft water).  
Note: Always install a bypass, either a 3-way valve system  
or the standard bypass for the valve you have.This will allow  
you to shut off the water supply to the softener, but still have  
water in the house if the softener is in need of repair.  
Select location that is easily accessible to 110vac power. A  
15-foot power cord is provided.  
After a location has been determine install bypass onto the  
control valve. (Figures 1 and 3 show standard bypass on  
valve.) (Figures 2 and 4 show 3-way by pass plumbing.)  
You will also need a drain close by for disposal of regenerat-  
ed wastewater.  
Note: If installing a 3-way bypass valve, do so now.  
Close main water supply valve, at the well or at the water meter.  
Shut off electrical or fuel supply to the water heater.  
Open all faucets to drain pipes.  
Leave enough room between walls so you can easily add salt  
when needed.  
Locate the water softener at least 10 feet away from the hot  
water heater so that hot water does not backup and damage  
the softener.  
Note: If installing standard bypass, move to step 3.  
Make sure water softener is in a level spot. You may be  
required to put the softener on a platform, such as a piece of  
3/4” plywood and shimmed to become level.  
The bypass (provided) easily connects to the valve body  
using nuts that only require hand tightening. The split ring  
retainer design holds the nut on and allows load to be spread  
over the entire nut surface area reducing the chance for leak-  
age. Make certain the nut is placed on first, then the split  
retainer ring, followed by the o-ring to make the seal. A silicon  
lubricant may be used on the black o-ring seals. This design  
allows for an approximate 2-degree misalignment of the  
plumbing. This design will allow for minor plumbing misalign-  
ments, but should never handle the weight of the plumbing  
system.  
Make sure softener is behind any other water conditioning  
systems installed in series, except a system that is for taste  
and odor or a Reverse Osmosis system.  
Select a location were water damage will be least likely to  
occur if a leak should develop.  
If installing the softener in an outside location make sure  
to protect from the elements, such as rain, sunlight, and  
contamination.

When installing sweat copper follow state and  
federal codes by using a lead free solder and  
flux. Use a joint compound to seal threaded pipe.  
Some homes use the cold water pipes for an elec-  
trical ground (metal only). Whenfinished with  
plumbing, a ground wire should bre connected  
to the copper pipes to complete the ground cur-  
cuit. Use two clamps and #4 copper wire for this.

INSTALLATION  
STEP 3:  
Note: When assembling the installation fitting  
package, connect the fitting to the plumbing  
system first and then attach the nut, split ring  
and o-ring. Heat from soldering or solvent  
cements may damage the nut, split ring, and  
o-ring. Make sure solder joints are cool  
before assemble is started.  
Move softener  
into place  
Make sure floor is level.  
Install shims if needed.  
Measure, cut, and install  
pipe and fittings to the  
bypass valve (dry fit only  
to make sure you have a  
proper fit) inlet and out-  
let side. Be sure hard  
water is supplied to the  
inlet side. Trace pipe to  
be sure.  
joints should be cool and solvent cements should be set  
before installing the nut, split ring, and o-ring. Avoid get-  
ting primer and solvent cement on any part of the o-  
rings, split rings, and bypass valve or control valve.  
Solvent cements and primers should be used in accor-  
dance with the manufacturer’s instructions.  
Slip the nut onto the fitting first, then the split ring second  
and the o-ring last. Hand tighten the nut. If the fitting is  
leaking tightening the nut will not stop the leak. Remove  
the nut, remove the fitting, and check for damage or mis-  
alignment of the o-ring.  
The installation fittings connect to the control valve or the  
bypass valve using nuts that only require hand tightening.  
Hand tighten nut connections between control valve and  
installation fittings, control valve and bypass valve, and  
bypass valve and installation fittings allow for easy serv-  
iceability. Do not use a pipe wrench to tighten nuts on  
installation fittings. Hand tighten only.  
Do not use pipe dope or other sealant on threads. Teflon  
tapemust be used on the threads of the 1" NPT elbow  
and the 1/4" NPT connection and on the threads for the  
drain line connection.Teflon tape is not necessary on the  
nut connection or caps because of o-ring seals.

STEP 4: Move brine  
tank next to softener  
and connect brine  
draw line to value.  
1” BRASS SWEAT  
3/4” BRASS SWEAT  
With brine tank next to the soft-  
ener tank connect the brine  
drawline to valve body.  
Control valves that use a regen-  
erant, come equipped with a  
3/8" refill flow control assembly.  
To complete the regenerant line connections orientate the  
outlet in the desired direction and push the plastic insert into  
the poly tube. Push the poly tube into the nut. Do not use  
pipe dope or other sealant on threads. The threads for the  
compression nut do not need Teflon tape. Tighten the nut  
securely to create a pressure tight connection. A pliers or  
crescent wrench may be used to tighten or unscrew the nut.  
The nut, gripper and retainer sleeve is a 3-piece assembly  
that can come apart if removed from the elbow body. Parts  
must be reassembled exactly as shown in refill flow con-  
trol assembly drawing to function properly. If the nut is  
completely removed from the body, slip the nut, plastic  
gripper and retainer sleeve on to the tube then tighten on  
to the fitting. Complete the connection by installing the  
loose end of the tubing to the brine valve in the salt tank.  
Figure 8: Four types of installation fittings.  
Split ring retainer design holds the nut on and allows load  
to be spread over the entire nut surface area reducing the  
chance for leakage. The split ring design, incorporated into  
the installation fittings allows approximately 2 degrees off  
axis alignment to the plumbing system. The installation fit-  
tings are designed to accommodate minor plumbing mis-  
alignments but are not designed to support the weight of a  
system or the plumbing.  
When assembling the installation-fitting package, connect  
the fitting to the plumbing system first and then attach the  
nut, split ring and o-ring. Heat from soldering or solvent  
cements may damage the nut, split ring, or o-ring. Solder

INSTALLATION  
STEP 5: Connect the Drain Line  
If the drain line is a 5/8" flexible poly tube, slide the nut onto  
the poly tube, then place the poly tube insert into the end of  
the poly tube and tighten the nut on to the 3/4" drain line fit-  
ting. The nut is only designed for use with flexible poly tube.  
Use other nuts if attaching different materials. Run line to a  
drain. Making sure you have a 1 1/2" airgap. You may use a  
floor drain, standpipe or any open type drain (see Fig 10).  
Do not use Vaseline, oils, or other unacceptable lubricants on  
o-rings. A silicon lubricant may be used on the black o-ring.  
Use a pliers or crescent wrench to tighten or unscrew the nut.  
Do not use a pipe wrench to tighten or loosen nut. Do not use  
pipe dope or other sealant on threads. Use Teflon tape on the  
threads of the drain line control fitting when installing 3/4"  
NPT or 1" straight fitting.  
Figure 9: Brine Draw Connection.  
Figure 11: Drain Line Connection  
Figure 10: Also be sure drain line has an air gap.  
STEP 5: Start-up  
Place the bypass valve in the “bypass” position or mode  
(see figures 12-14 below.)  
This will put the valve in manual mode. Now press the Regen  
button twice.This will put the system in backwash. Slowly open the  
inlet valve. (Open the valve a little at a time, pausing several times  
to allow the unit to fill slowly and expel air.) When the tank has filled  
and a steady flow to the drain is achieved, let the system run until  
clear water can be seen coming from the drain line. When water is  
clear press the regen button 4 times. This will take the valve back  
to service position. Open several cold water and hot water faucets  
and let run until hot water heater is full and cold water faucets have  
expelled trapped air. Turn electrical power back on or re-light the  
hot water heater. Now continue with control valve setup.  
Open the main water supply valve.  
Open a couple of cold water faucets that are to be conditioned  
and let run until air is expelled and pipes are full.  
Open the outlet valve of the bypass.  
Close the bypass valve.  
Press and hold the regen button on the keypad for 3 seconds.

If there is a demand for water when the system is regenerating,  
untreated water will be used.  
When the system begins to regenerate, the display will change  
to include information about the step of the regeneration process

SYSTEM COMPONENTS DESCRIBED  
The drive bracket holds the PC board, the motor, the drive  
gears and the drive gear cover in place.  
Components:  
The control valve consists of the following components  
1. Drive Assembly  
The PC board receives and retains information, displays the  
information,determines when to regenerate and initiates  
regeneration.The display shows different types of information  
in the initial system set up (for softeners or filters), installer  
displays/settings, diagnostics, and valve history or user dis-  
plays/settings.  
2. Drive Cap Assembly, Main Piston and  
Regenerant Piston  
3. Spacer Stack Assembly  
4. Injector Cap, Screen, Injector Plug and Injector  
5. Refill Flow Control Assembly or Refill Port Plug  
6. Drain Line Flow Control and Fitting Assembly  
7. Water Meter or Meter Plug  
8. Installation Fitting Assemblies  
9. Bypass Valve (optional)  
The PC board’s two-prong jack connects wires to the direct  
current (DC) motor. The motor is held in place on the drive  
bracket by a spring-loaded clip and a small bulge in the plas-  
tic, which fits in one of the slots on the motor housing. The  
motor turns drive gears that drive the piston to cycle positions  
for backwashing, regeneration, rinsing, refill or service. The  
motor is fully reversible (turns both ways) and changes direc-  
tion of rotation to change the direction of piston motion. The  
motor is easily replaced if necessary.  
DRIVE ASSEMBLY  
The drive assembly consists of the following parts:  
There are three drive gears held in place by the drive gear  
cover. All three drive gears are the same size. A reflective  
coating is applied to the gears. As the center drive gear turns  
a light shines on the coating and a light sensing diode deter-  
mines if a light pulse was returned. The PC board counts the  
pulses and determines when to stop driving the motor.

The drive gears turn the main gear of the drive cap assembly,  
which moves the piston. The screw-driven, horizontally mov-  
ing piston stops at specific positions to direct the flow of water  
to backwash, regenerate, rinse or refill. The PC board deter-  
mines the position of the piston by counting pulses produced  
when the piston is moved. An optical sensor looking at one of  
the reduction drive gears generates these pulses. Each cycle  
position is defined by a number of pulses. The counter is  
zeroed each time the valve goes to the service position. The  
PC board finds the service position by noting the increase in  
current delivered to the motor when the mechanical stop at  
the service position is reached.This method of controlling pis-  
ton position allows for greater flexibility and requires no  
switches or cams.

through the media to regenerate the bed.  
The injector provides a consistent regenerant/water mixture ratio  
over the entire operating pressure range of the control valve. The  
injector provides good performance in a variety of applications,  
which may involve elevated drain lines and long regenerant draw  
lenghts. Injectors are chosen by knowing the type, amount, and  
regenerant flow rate for a particular type of media. The color-  
coded injectors give different regenerant draw, slow rinse and total  
flow rates over the pressure range. See Table 10 for color codes.  
One of two main pistons is always used:  
1. The down flow piston which is used when the control  
valve is used as a down flow softener, regenerating  
filter or nonregenerating filter: or  
2. The up flow piston, which is used when the control valve  
is used as an up flow softener.  
REFILL FLOW CONTROL Assembly  
The refill flow control assembly consists of a refill flow elbow, refill  
flow control retainer assembly, refill flow control, poly tube insert  
and nut assembly. The refill flow control retainer fits in the refill  
elbow. The refill flow control retainer houses the refill flow control,  
which controls the flow rate when the regenerant tank is being  
refilled. The refill flow control is a flexible washer-like part with a  
small orifice and a precision molded contour that delivers a  
steady 0.5 gpm regenerant tank refill rate at varying inlet  
pressures. Refill is accomplished with treated water.  
If the control valve is used as a softener or a regenerating  
filter, a regenerant piston must be attached to the main piston.  
If the control valve is to be used on system that does not  
require a regenerant to be added the regenerant piston must  
be removed.  
SPACER STACK ASSEMBLY  
The refill flow control assembly is installed in an easy to access  
refill elbow located on top of the control valve. The refill flow con-  
trol assembly is attached to the control valve with a locking clip.  
The locking clip allows the elbow to rotate 270 degrees so the  
outlet can be orientated towards the regenerant tank.  
The spacer stack assembly provides the necessary flow pas-  
sage for water during the different cycles.The all-plastic spac-  
er stack assembly (patent pending) is a one-piece design,  
which allows the stack to be removed using your fingers.  
The exterior of the stack is sealed against the body bore with  
self-lubricating EPDM o-rings while the interior surface is  
sealed against the piston using slippery self cleaning direc-  
tional (oneway) silicone lip seals.The lip seals are red or clear  
in color and have a special slippery coating so that the piston  
does not need to be coated or lubricated.  
DRAIN LINE FLOW CONTROL/Fitting  
The drain line flow control assembly includes a drain line flow  
control and a fitting. The drain line flow control allows proper  
media bed expansion by regulating the flow rate to the drain.  
The drain line flow control is a flexible washer-like part with an  
orifice and a precision molded contour. The flow rates are  
within +- 10% over the pressure range of 1-0 psi to 125 psi.  
The flexible washer-like parts are identified with three num-  
bers, which correspond to the flow rate in gallons per minute.  
See Table 11.  
INJECTOR  
T
he screen, injector and/or injector plug(s) are installed under  
the injector cap in an easy to access location on top of the valve.  
The injector cap contains four slots so no water accumulates  
in the cap. The injector cap is designed to be hand tightened.  
The drain line flow control and fitting are located on top of the  
control valve and replaceable without the use of special tools.  
Under the injector cap there is an easy to clean removable  
screen to prevent fouling of the injector. There are two holes  
under the injector cap labeled “DN” and “UP”. The holes will be  
filled with a plug or an injector.

The plug (#KC113010-IZ) prevents water from traveling through  
the pathway. The injector lets water pass through the pathway.  
The self-priming injector increases the velocity of the water, cre-

liquid regenerant, such as sodium chloride (brine), potassium  
permanganate, sodium hydroxide, hydrochloric acid, etc. The  
regenerant blends with the stream of water, which passes

1/4" drain line elbow, which accommodates 5/8" poly tube or  
3/4" NPT drain line connections. The optional nut and poly  
tube insert for the 3/4" drain line elbow is designed for use  
with flexible poly tube only. The 3/4" drain line elbow can be  
rotated 180 degrees so the outlet can be orientated to the  
nearest drain. The same retainer is used for all drain line flow  
controls for the 3/4" fitting.  
The installation fitting assemblies are sold in pairs and  
consist of two fittings, two nuts, two split rings and two o-  
rings. The installation fitting assemblies and the bypass valve  
are sold separately from the control valve.  
Bypass Valve  
The bypass valve is typically used to isolate the control valve  
from the plumbing system’s water pressure in order to per-  
form control valve repairs or maintenance. The W100SM  
bypass valve is particularly unique in the water treatment  
industry due to its versatility and state of the art design  
features. The 1" full flow bypass valve incorporates four posi-  
tions including a diagnostic position that allows service per-  
sonal to work on a pressurized system while still providing  
untreated bypass water to the facility or residence. Its  
completely non-metallic, all plastic design allows for easy  
access and serviceability without the need for tools.  
Water Meter or Meter Plug  
The water meter is installed on the outlet side of the control  
valve. The water meter uses a turbine to total gallons of treat-  
ed water. The turbine rotates with the flow of water and  
reports its rate of rotation through Hall-effect 8 circuitry to the  
printed circuit (PC) board. This rotation permits the PC board  
to record the total volume of treated water and the flow rate.  
The small centrally located magnet is shielded from water,  
which reduces substantially iron-fouling problems with the  
turbine. The turbine is accurate to within 5% over a wide  
operating flow rate range (0.25 gpm up to control valve max-  
imums) and has a very low pressure drop. Water used for  
regeneration is not metered. If the control valve is set to pre-  
fill the regenerant, water used between the prefill cycle up to  
the start of the regeneration cycle is metered. If the control  
valve is in regeneration mode (e.g. a backwash cycle) and  
there is a water demand that water usage is not metered.  
The bypass body and rotors are glass filled Noryl and the  
nuts and caps are glass filled polypropylene. All seals are  
self-lubricating EPDM to help prevent valve seizing after long  
periods of nonuse. Internal o-rings can easily be replaced if  
service is required.  
The bypass consists of two interchangeable plug valves that  
are operated independently by red arrow shaped handles.  
The handles identify the flow direction of the water. The plug  
valves enable the bypass valve to operate in four positions.  
1. Normal Operation Position: The inlet and outlet handles  
point in the direction of flow indicated by the engraved  
arrows on the control valve. Water flows through the  
control valve during normal operation and this position  
also allows the control valve to isolate the media bed  
during the regeneration cycle. (See Figure 17)  
2. Bypass Position: The inlet and outlet handles point to the  
center of the bypass, the control valve is isolated from the  
water pressure contained in the plumbing system.  
Untreated water is supplied to the plumbing system.  
(See Figure 18)  
3. Diagnostic Position: The inlet handle points in the direction  
of flow and the outlet handle points to the center of bypass  
valve, system water pressure is allowed to the control  
valve and the plumbing system while not allowing water  
to exit from the control valve to the plumbing.  
(See Figure 19)  
4. Shut Off Position: The inlet handle points to the center of  
the bypass valve and the outlet handle points in the  
direction of flow, the water is shut off to the plumbing  
systems. If water is available on the outlet side of the  
softener it is an indication of water bypass around the  
system (i.e. a plumbing connection somewhere in the  
building bypasses the system). (See Figure 20)  
When facing the front of the control valve, the water meter is  
positioned on the left-hand side of the control valve. Allow  
sufficient clearance to clean and repair the water meter with  
out disconnecting the plumbing or disassembling any other  
parts of the control valve.  
A unique feature of this control valve is the ability to display  
actual water usage for the last 63 days.The values are initially  
stored as "_" because it is is unknown. As days pass values  
are stored as “O” for no flow or the actual number of galons.  
The counting of the gallons starts at the regeneration  
time. If no regeneration time can be set (i.e. when the valve is  
set for immediate regeneration) the counting, of gallons starts  
at 12 a.m. Day 1 is yesterday, day 2 the day before yesterday,  
etc. As new values are added the oldest history disappears.  
Another unique feature is that the valve automatically calcu-  
lates a reserve capacity when set up as a softener with  
“Gallons Capacity” set to “AUTO”. The reserve capacity for a  
given day of the week is the middle value stored for the last  
three non-trivial water usages (i.e. less than 20 gallons day)  
in seven-day intervals which is then adjusted either upward or  
downward depending upon the difference between today’s  
water usage and the estimated reserve capacity.  
Installation Fitting Assemblies  
The installation fittings are used to connect the optional  
bypass or the control to the plumbing system. There are four  
installation-fitting assemblies available:  
1. 1" NPT elbow  
2. 3/4" & 1" PVC solvent weld elbow fitting  
3. 1" straight brass sweat fitting **  
4. 3/4" straight brass sweat Fitting **  
Both elbow fittings have a unique drill out feature to allow a  
1/4" NPT connection to the inlet and/or outlet which can be  
* Some semiconductor materials exhibit a phenomenon in the presence of a magnetic  
field that is adaptable to sensing devices. When a current is passed through one pair of  
wires attached to a semiconductor, another pair of wires properly attached and orient-  
ed with respect to the semiconductor will develop a voltage proportional to the magnet-  
ic field present and the current in the other pair of wires. Holding the exiting current  
constant and moving a permanent magnet near the semiconductor produces a voltage  
output proportional to the movement of the magnet. Hall-effect devices provide a  
high-speed response, excellent temperature stability and no physical contact.

Service Instructions  
To reassemble seat the bottom of the drive bracket so the  
notches are engaged at the bottom of the drive back plate.  
Push the top of the drive bracket towards the two latches.The  
drive bracket may have to be lifted slightly to let the threaded  
piston rod pass through the hole in the drive bracket. Maintain  
a slight engaging force on top of the drive bracket while  
deflecting the bracket slightly to the left by pressing on the  
side of the upper right corner. This helps the drive gears  
mesh with the drive cap assembly. The drive bracket is  
properly seated when it snaps under the latches on the drive  
back plate. If resistance is felt before latching, then notches  
are not fully engaged, the piston rod is not in hole, the wires  
are jammed between the drive bracket and drive back plate,  
or the gear is not engaging the drive cap assembly.  
DRIVE ASSEMBLY  
Remove the valve cover to access the drive assembly.  
Disconnect the power source plug (black wire) from the PC  
board prior to disconnecting the motor or water meter plugs  
from the PC board. The motor plug connects to the two-pin  
jack on the left-hand side of the PC board. The power source  
plug connects to the four-pin jack. The four-pin jack is  
between the two-pin and three-pin jacks. The water meter  
plug (gray wire) connects to the three.  
The PC board can be removed separately from the drive brack-  
et but it is not recommended. Do not attempt to remove the dis-  
play panel from the PC board. Handle the board by the edges.  
To remove the PC board from the drive bracket, unplug the  
power, water meter and motor plugs from the PC board. Lift the  
middle latch along the top of the drive bracket while pulling out-  
ward on the top of the PC board. The drive bracket has two  
plastic pins that fit into the holes on the lower edge of the PC  
board. Once the PC board is tilted about 45˚ from the drive  
bracket it can be lifted off of these pins. To reinstall the PC  
board, position the lower edge of the PC board so that the  
holes in the PC board line up with the plastic pins. Push the top  
of the PC board towards the valve until it snaps under the  
middle latch, weave the power and water meter wires into the  
holders and reconnect the motor water meter and power plugs.  
To inspect drive gears, the drive gear cover needs to be  
removed. The drive gear cover is held in place on the drive  
bracket by three clips. The largest of the three clips is always  
orientated to the bottom of the drive bracket. Before trying to  
remove the drive gear cover, the drive bracket must be  
removed from the drive back plate. The drive gear cover can  
be removed from the drive bracket without removing the  
motor or the PC board. Simultaneously, push in and down on  
the large clip at the bottom and the clip on the left-hand side  
of the drive bracket behind the PC board. Keep your other  
fingers behind the drive gear cover so the drive gears do not  
drop on the ground. Replace broken or damaged drive gears.  
Do not lubricate any of the gears. Avoid getting any foreign  
matter on the reflective coating because dirt or oils may inter-  
fere with pulse counting.  
The drive bracket must be removed to access the drive cap  
assembly and pistons or the drive gear cover. It is not  
necessary to remove the PC board from the drive bracket to  
remove the drive bracket.To remove the drive bracket start by  
removing the plugs for the power source and the water meter.  
Unweave the wires from the side holders. Two tabs on the  
top of the drive back plate hold the drive bracket in place.  
Simultaneously lift the two tabs and gently ease the top of  
the drive bracket towards your body. The lower edge of  
the drive bracket has two notches that rest on the drive  
back plate. Lift up and outward on the drive bracket to  
disengage the notches.  
The drive gear cover only fits on one way, with the large clip  
orientated towards the bottom. If all three clips are outside of  
the gear shroud on the drive bracket the drive gear cover slips  
easily into place.  
The drive bracket does not need to be removed from the drive  
plate if the motor needs to be removed. To remove the motor,  
disconnect the power and motor plugs from the jacks on the PC

motor at least a 1/4 turn in either direction before gently pulling  
on the wire connectors to remove the motor. Pulling directly on  
the wires without rotating the motor may break the wires off the  
motor.  
Reattach the main piston to the drive cap assembly. Reattach  
the regenerant piston (if needed) to the main piston. Do not  
lubricate the piston rod, main piston or regenerant piston.  
Lubricant will adversely affect the red or clear lip seals. Reinsert  
the drive cap assembly and piston into the spacer stack  
assembly and hand tighten the drive cap assembly. Continue to  
tighten the drive cap assembly using a screwdriver as a ratchet  
until the black oring on the spacer stack assembly is no longer  
visible through the drain port. Excessive force can break the  
notches molded into the drive back plate. Make certain that the  
main drive gear still turns freely. The exact position of the piston  
is not important as long as the main drive gear turns freely.  
Replace the motor if necessary. Do not lubricate the motor or the  
gears. When reinstalling the motor gently turn the motor while  
inserting so that the gear on the motor meshes with the gears  
under the drive gear cover and the small plastic bulge engages  
one of the slots on the motor housing. Reconnect the motor plug  
to the two-pronged jack on the lower left-hand side of the PC  
board. If motor will not easily engage with drive gear when rein-  
stalling, lift and slightly rotate motor before reinserting.  
Replace the valve cover. After completing any valve mainte-

AND REGENERANT PISTON  
SPACER STACK ASSEMBLY  
To access the spacer stack assembly remove the drive  
assembly, drive cap assembly and piston. The spacer stack  
assembly can be removed easily without tools by using thumb  
and forefinger. Inspect the black o-rings and red or clear lip seals  
for wear or damage. Replace the entire stack if necessary. The  
spacer stack assembly has been 100% tested at the factory to  
insure proper orientation of one-way seals. Do not disassemble  
the stack.  
The drive assembly must be removed to access the drive cap  
assembly. The drive cap assembly must be removed to access  
the piston(s). The drive cap assembly is threaded into the con-  
trol valve body and seals with an o-ring.To remove the drive cap  
assembly, use the special plastic wrench or insert a 1/4" to 1" flat  
bladed screwdriver into one of the slots around the top 2" of the  
drive cap assembly so it engages the notches molded into the  
drive back plate around the top 2" of the piston cavity. See  
Figure 5. The notches are visible through the holes. Lever the  
screwdriver so the drive cap assembly turns counter clockwise.  
Once loosened unscrew the drive cap assembly by hand and  
pull straight out.  
The spacer stack assembly may be chemically cleaned (dilute  
sodium bisulfite or vinegar) or wiped with a soft cloth.  
The spacer stack assembly can be pushed in to the control valve  
body bore by hand. Since the spacer stack assembly can be  
compressed it is easier to use a blunt object (5/8" to 1-1/8" in  
diameter) to push the center of the assembly into the control  
valve body. The assembly is property seated when at least four  
threads are exposed (approximately 5/8"). Do not force the  
spacer stack assembly in. The control valve body bore interior  
can be lubricated with silicone to allow for easy insertion of the  
entire stack. Do not use silicone or any other type of lubricant on  
the red or clear lip seals or the piston.  
The drive cap assembly contains the drive cap, the main drive

After completing any valve maintenance, press and hold NEXT  
and REGEN buttons for 3 seconds or unplug power source jack

gear, drive cap spline, piston rod and various other parts that  
should not be dissembled in the field. The only replaceable part  
on the drive cap assembly is the o-ring. Attached to the drive cap  
assembly is the main piston (downflow or upflow) and if a regen-  
erant is used, a regenerant piston.  
The regenerant piston (the small diameter one behind the main  
piston) is removed from the main piston by unsnapping it from  
its latch. Chemically clean in dilute sodium bisulfite or vinegar or  
replace the regenerant piston if needed. To remove the main-  
downflow or upflow piston fully extend the piston rod and then  
unsnap the main piston from its latch by pressing on the side  
with the number. Chemically clean in dilute sodium bisulfite or  
INJECTOR CAP, SCREEN, INJECTOR  
PLUG AND INJECTOR  
Unscrew the injector cap and lift off. Loosen cap with special  
plastic wrench or pliers if necessary. Attached to the injector cap  
is a screen. Remove the screen and clean if fouled.

The plug and/or injector can be pried out with a small  
water meter.  
screwdriver. The plug can be wiped clean. If the plug leaks  
replace the entire plug. The injector consists of a throat and a  
nozzle. Chemically clean the injector with vinegar or sodium  
bisulfite. The holes can be blown out with air. Both pieces have  
small diameter holes that control the flow rates of water to insure  
that the proper concentration of regenerant is used. Sharp  
objects, which can score the plastic, should not be used to clean  
the injector. Scoring the injector or increasing the diameter of the  
hole could change the operating parameters of the injector.  
Two holes are labeled DN and UP. Check for compliance with  
one of the following:  
The water meter wire does not need to be removed from the PC  
board if the water meter is only being inspected and cleaned.  
To remove the water meter assembly, unscrew the meter cap on  
the left side of the control valve. Pliers may be used to unscrew  
the nut if necessary.  
With the nut removed, a slot at the top of the water meter is  
visible. Twist a flat blade screwdriver in the slot between the  
control valve body and the meter. When the meter is part way  
out it is easy to remove the water meter from the housing.  
Once the water meter is removed from the control valve body,  
use your fingers to gently pull forward on the turbine to remove  
it from the shaft.  
a. For downflow systems, the appropriate size injector is  
located in the “DN” hole, a plug is in the “UP” hole and  
the piston is a combination of the downflow main piston and  
the regenerant piston;  
b. For upflow systems, the appropriate size injector is located  
in the “UP” hole, a plug is in the “DN” hole and the piston  
is a combination of the upflow main piston and the regenerant  
piston; or  
c. For backwash only systems, a plug is in the “DN” hole and  
in the “UP” hole, and the piston only has a downflow  
main piston (the regenerant piston must be removed) and a  
plug is in the refill flow control position.  
Do not use a wire brush to clean. Wipe with a clean cloth or  
chemically clean in dilute sodium bisulfite or vinegar. The turbine  
can be immersed in the chemical. Do not immerse electronics. If  
the turbine is scored or damaged or the bearings on the turbine  
are worn replace the turbine.  
Do not lubricate the turbine shaft. The turbine shaft bearings are  
pre-lubricated. Do not use Vaseline, oils or other unacceptable  
lubricants on the o-ring. A silicon lubricant may be used on the  
black o-ring.  
Snap the turbine on the shaft and reinsert the water meter into  
the side slot. Hand tighten the nut. Do not use a pipe wrench to  
tighten nut.  
Push the plug(s) and/or injectors firmly in place, replace the  
screen and hand tighten the injector cap.  
BYPASS VALVE  
REFILL FLOW CONTROL ASSEMBLY  
OR REFILL PORT PLUG  
The working parts of the bypass valve are the rotor assemblies  
that are contained under the bypass valve caps. Before working  
on the rotors, make sure the system is depressurized. Turn the  
red arrow shaped handles towards the center of the bypass valve  
and back to the arrow direction several times to ensure rotor is  
turning freely.  
To clean or replace the refill flow control, pull out the elbow-  
locking clip and then pull straight up on the elbow. Replace the  
elbow-locking clip in the slot so that it is not misplaced. Twist to  
remove the white flow control retainer. The flow control can be  
removed by prying upward through the side slots of the retainer  
with a small blade flat screwdriver.  
The nuts and caps are designed to be unscrewed or tightened  
by hand. If necessary a pair of pliers can be used to unscrew the  
nut or cap. Do not use a pipe wrench to tighten or loosen nuts or  
caps. Do not place screwdriver in slots on caps and/or tap with a  
hammer. To access the rotor, unscrew the cap and lift the cap,  
rotor and handle out as one unit. Twisting the unit as you pull it  
out will help to remove it more easily.There are three o-rings: one  
under the rotor cap, one on the rotor stem and the rotor seal.  
Replace worn o-rings. Clean rotor. Reinstall rotor.  
Chemically clean the flow control or the white flow control  
retainer using dilute sodium bisulfite or vinegar. Do not use a  
wire brush. If necessary, replace the flow control o-ring on  
the flow control retainer, or the o-ring on the elbow.  
Reseat the flow control so the rounded end is visible in the flow  
control. Reseat the white flow control retainer by pushing the  
retainer into the elbow until the o-ring seats. Remove locking clip,  
push down on elbow to reseat and insert locking clip.  
When reinstalling the red arrow handles be sure that:  
1. O-rings on both rotors face to the right when being viewed  
from the front of the control valve when the handle pointers  
are lined up with the control valve body arrows; or  
Do not use Vaseline, oils, or other unacceptable lubricants on  
o-rings. A silicon lubricant may be used on the o-ring on elbow or  
the white retainer.  
2. Arrows point toward each other in the bypass position.  
WATER METER OR METER PLUG  
Since the handles can be pulled off, they could be accidentally  
reinstalled 180° from their correct orientation. To install the red  
arrow handles correctly, keep the handles pointed in the same  
direction as the arrows engraved on the control valve body while  
tightening the bypass valve caps.  
The water meter assembly is connected to the PC board by a  
wire. If the entire water meter assembly is to be replaced, remove  
the control valve cover and remove the power source and water  
meter plugs from the PC board. Unlatch the drive assembly and  
lean it forward. Unthread the water meter wire from the side of the  
drive assembly and through the drive back plate. To reinstall,  
rethread the water meter wire through the drive back plate and  
the side of the drive assembly. Reattach the drive assembly  
and the water meter and power plugs.  
After completing, any valve maintenance, press and hold NEXT  
and REGEN buttons for 3 seconds or unplug power source jack  
(black wire) and plug back in. This resets the electronics and  
establishes the service piston position. The display should flash  
all wording then flash the software version (e.g. 154) and then  
reset the valve to the service position.  
If no water meter wire is visible, then a plug is installed not a
