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:
Hardness gpg Tannins (Humic Acid) ppm
Iron (Fe) ppm Hydrogen Sulfide (H2S) ppm
Manganese (Mn) ppm Other ppm
pH ppm Other ppm
IMPORTANT NOTES
IMPORTANT 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.
1-1
• 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!

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
Step 1) Remove the unit from the shipping box and remove all packaging. Ensure no freight damage has occurred since shipment from our manufacturing
facility. Locate the parts package and install the bypass and adapter fittings on the control valve to facilitate the connection to the customer’s
water supply.
CAUTION
To reduce the risk associated with property damage due to water leakage:
• On plastic fittings, never use pipe sealant or pipe dope. Use PTFE thread tape only, pipe dope properties may deteriorate plastic;
• Take care when using pliers or pipe wrenches to tighten plastic fittings, as damage may occur if over tightening occurs.
Step 2) NOTE: Extension legs should be installed only whenever a salt dosage on any model softener is more than 15 lbs. Models utilizing 15” x 15” x
34” brine tanks require salt grid extension legs when salting the softener above 15 lbs. of salt or more. Grid legs extension kits are provided
for CWS200 units. All other models requiring extension leg kits can be ordered through our Customer Service Department at 1-866-990-
9785.
Verify all packaging materials have been removed from the brine tank. On all units, legs rest on bottom of the brine tank.
Step 3) Shut off all water at main supply valve. On a private well system, turn off power to the 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.
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.
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.
Step 6) The controls allow for either a 3/4” NPT connection or 5/8” poly tubing for use as a drain line connection.
CAUTION
To reduce the risk associated with property damage due to water leakage:
• On plastic fittings, never use pipe sealant or pipe dope. Use PTFE thread tape only, pipe dope properties may deteriorate plastic;
• Take care when using pliers or pipe wrenches to tighten plastic fittings, as damage may occur if over tightening occurs.

Step 7) 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” ID up to 15 ft. when discharge is lower than INLET.
2) 5/8” ID up to 15 ft. when discharge is slightly higher than the INLET.
3) 3/4” 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 8) Position DRAIN LINE over drain and secure firmly. To prevent backsiphoning of sewer
water, provide an air-gap of at least 2” 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 9) Connect one end of the included 3/8” black Polyethylene tub-
ing to the brine fitting located on the left side of the CONTROL
VALVE. Connect the other end to the SAFETY BRINE VALVE EL-
BOW inside of the brine well in the brine tank. To do so remove
the retaining clip from the brine line fitting on the control valve.
The retaining clip is holding a plastic insert sleeve and needs
to be inserted into the polyethylene tubing before installing the
tubing into the fitting elbow and hand tighten only. CAUTION:
Do not use pliers or wrenches to tighten as damage may oc-
cur and will void the manufacturer’s warranty.
Step 10) 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 11) Make certain BYPASS VALVE INLET and OUTLET KNOBS ARE IN
“BYPASS” position. After all plumbing connections have been
completed, open main water shut-off valve and restore power
to well pump. Check for leaks and correct as necessary.
Step 12) Plug CONTROL VALVE POWER CORD into 120v/60Hz, non-switched
power source. Program the control valve (refer to page 3-1).
NOTE: Regeneration settings for the control valve are factory
preset. The control valve design permits adjustment of the salt
setting. This adjustment may be necessary when unusual op-
erating conditions exist, such as high concentrations of iron,
manganese or hardness and/or high flow rates or daily water
consumption.
Step 13) Manually stage control to BACKWASH POSITION. Press and hold
REGEN button for 3 seconds. The valve will advance to BACKWASH POSITION. Unplug power cord to prevent the
unit from advancing automatically.
Step 14) Partially open INLET knob on bypass valve (Figure 4). This will allow the unit to fill slowly from the bottom up,
reducing 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 and outlet knobs on the bypass can be fully opened
(refer to Figure 4).
Step 15) Plug the power cord back into the power source. Press the REGEN button and wait for the valve to advance to
the next regeneration position. Repeat the process until the valve is in Service Position (Time will be on the
display).
Step 16) Refer to Section 3: Control Valve Programming and Regeneration Instructions, on how to set control valve
for proper set up and regeneration settings.
SPECIAL SERVICE INSTRUCTIONS:
Under normal circumstances removal of valve should not be required. However, if it must be removed, it can be done
by disassembling the quick release clamp, and latch. Pressure should be relieved before attempting any disassem-
bly. 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.

User Display Settings
General Operation
When the system is operating, one of two displays will be
shown. Pressing NEXT will alternate between the displays.
One of the displays is always the current time of day. The sec-
ond display is one of the following: days remaining or capacity
remaining. Days remaining is the number of days left before
the system goes through a regeneration cycle. Capacity re-
maining is the number of gallons that will be treated before the
system goes through a regeneration cycle. The user can scroll
between the displays as desired.
OR
REGEN TODAY will be
displayed if a regeneration
is expected “Tonight.”
When the system begins to regenerate, the display will change to include information about the step of the regeneration process and the time
remaining for that step to be completed. The system runs through the steps automatically and will reset itself to help provide treated water
when the regeneration has been completed.
Manual Regeneration
Sometimes there is a need to regenerate the system sooner than
when the system calls for it, usually referred to as manual regen-
eration. There may be a period of heavy water usage because of
guests or a heavy laundry day.
To initiate a manual regeneration at the present delayed regeneration time, press and release “REGEN”. The words “REGEN TODAY” will flash
on the display to indicate that the system will regenerate at the preset delayed regeneration time.
NOTE: If you pressed the “REGEN” button in error, pressing the button again will cancel the request.
To initiate a manual regeneration immediately, press and hold the “REGEN” button for 3 seconds. The system will begin to regenerate immedi-
ately. The request cannot be cancelled.
NOTE: If brine tank does not contain salt, fill with salt and wait at least two hours before regenerating.
Set Time of Day
The user can also set the time of day. Time should only need to be set after extended
power outages or when daylight saving time begins or ends. If an extended power outage occurs,
the time of day will flash on and off which indicates the time of day should be reset.
Step 1 - Press SET CLOCK.
Step 2 - Current Time (hour): Set the hour of the day using or button. AM/PM
toggles after 12. Press NEXT to go to Step 3.
Step 3 - Current Time (minutes): Set the minutes of the day using or buttons.
Press NEXT to exit Set Clock. Press “REGEN” to return to previous step.
If the system has called for a regeneration that will occur at the preset time of regeneration, the words “REGEN TODAY” will appear on the
display.
When water is being treated (i.e. water is flowing through the system) the word “SOFTENING” flashes on the display if a water meter is in-
stalled.
Regeneration Mode
Typically a system is set to regenerate at a time of low water usage. An example of a time with low
water usage is when members of a household are asleep. If there is a demand for water when the
system is regenerating, untreated water will be used.
REGEN TODAY will
Flash if a regeneration
is expected “Tonight.”

SECTION 4: MAINTENANCE
Replenishment of Salt Supply:
The salt storage capacity of the brine tank is approximately 180 lbs. (82 kg). During each regeneration a specific amount of salt is consumed, thus requiring
its periodic replenishment for a continuous supply of softened water (the frequency and salt dosage level is dependent on the regeneration schedule). Always
replenish salt before the supply is exhausted.
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. However the use of block salt is not encouraged due to its possible problems in making enough brine
for regeneration purposes.
Brine Tank Clean-Out:
To help prevent service problems the brine tank should be emptied and flushed out with a garden hose when dirt and other insolubles accumulate on a regular
basis. Shut off water inlet supply and depressurize the system before service.
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) Before loading salt, using a pail or garden hose, add enough water to the brine tank to cover the salt grid lower shelf on 15” x 15” x 34” brine tank at least
one (1) inch in depth. Then add initial salt to brine tank and add one (1) cup of unscented laundry bleach to the brine well.
(6) 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 help minimize these problems from occurring.
Please contact our Customer Service Department at 1-866-990-9785 for additional information.
Periodically Check Time of Day Setting:
Power outages will cause “TIME OF DAY” setting to become incorrect. To correct, refer to Section 3.
Malfunction of Unit:
Your water softener, under normal conditions, should provide years of virtually trouble-free service; however, since it is a mechanical device, it can malfunction.
(Please refer to our Troubleshooting Guide under Section 5, page 5-5 for additional information).
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. Please contact
our Customer Service Department at 1-866-990-9785 for additional information.
Special Service Instructions:
Under normal circumstances removal of valve should not be required. However, if it must be removed, it can be done by disassembling the quick release clamp, and
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 6. MAKE SURE ARROWS ON LATCH SIDE OF CLAMP ARE ALIGNED.

SECTION 5: CONTROL VALVE SERVICE INSTRUCTIONS
Drive Assembly:
Remove the valve cover to access the drive assembly.
IMPORTANT NOTE: 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
power source plug connects to the four-pin jack. The motor plug connects to the two-pin jack on the left-hand side of the PC board. The water meter plug (grey
wire) connects to the three-pin jack on the far right-hand side of the PC board.
The PC board can be removed separately from the drive bracket but it is not recommended. Do not attempt to remove the display 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 outward on the top of the PC board. The drive bracket has two plastic pins that fit into the holes on the lower edges
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.
The drive bracket must be removed to access the drive cap assembly and pistons or the drive cap 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 forward. The lower edge of the drive bracket has two notches that rest on the back plate. Lift up and outward on the drive bracket to disengage the
notches.
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 toward 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 the hole, the wires are jammed between the drive bracket and drive back plate, or the gear is not engaging
the drive cap assembly. To inspect the drive gears, the drive gear cover needs to be removed. Before trying to remove the gear cover, the drive bracket must be
removed from the drive back plate. (Refer to the proceeding instructions regarding removing the drive bracket from the drive back plate. The drive gear cover can
be removed from the drive bracket without removing the motor or the PC board.) 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. With the PC board facing up, push in and down on the large clip on the drive gear cover.
Handle the cover and the gears carefully so that the gears do not fall off of the pegs in the cover.
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
interfere with pulse counting.
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
and 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 board. Move the spring clip loop to the right and hold. Rotate the motor at least a 1/4 turn in either direction so the wires are vertical
(up & down) 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.
Replace the motor if necessary. Do not lubricate the motor or the gears. To reinstall the motor, move the spring clip loop to the right and hold. Gently turn the motor
while inserting so that the gear on the motor meshes with the gears under the drive gear cover. Release the spring clip loop and continue to rotate the motor until
the wires are horizontal and the motor housing engages the small plastic bulge inside the drive bracket motor retainer. Reconnect the motor plug to the two-pronged
jack on the lower left hand side of the PC board. If the motor will not easily engage with the drive gears when reinstalling, lift and slightly rotate the motor before
reinserting. Reconnect the power.
Replace the valve cover. 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.
181) and then reset the valve to the service position.
Drive Cap Assembly, Main Piston and Regenerant Piston:
The drive assembly must be removed to access the drive cap assembly. The drive cap assembly must be removed access the piston(s). The drive cap assembly
is threaded into the control valve body and seals with an o-ring. To remove the drive cap assembly use the special plastic wrench or insert a ¼” to ½” flat blade
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 2” or the piston cav-
ity. See Figure 7 on page 5-3. The notches are visible through the holes. Lever the screwdriver so the drive cap assembly turns to the left. Once loosened, unscrew
the drive cap assembly by hand and pull straight out. The drive cap assembly contains the drive cap, the main drive 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 and a regenerant piston.
The regenerant piston (the small diameter one behind the main piston) is removed form the main piston by pressing sideways and unsnapping if from its latch.
Chemically clean in dilute sodium or vinegar, or replace the regenerant piston if needed. To remove the main 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 vinegar, or replace the main piston.

5-3
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 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 o-ring on the spacer stack as-
sembly is no longer visible through the drain port. Excessive force can break the notches molded
into the dive back plate. Make certain that the main drive gear still turns freely.
The exact position is not important as long as the main drive gear turns freely. Reattach the drive
assembly to the control valve and connect all 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. 181) and then reset the
valve to the service position.
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 clear lip seals for wear or damage. Replace the entire stack if necessary.
Do not disassemble.
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 properly
seated with 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 clear lip seals
of the piston.
Reattach the drive cap assembly and piston(s) and the drive assembly.
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. 181) and then reset the valve to the service position.
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 screwdriver. The plug can be wiped clean. If the plug leaks replace the entire plug. The injec-
tor 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 a small
diameter holes that control the flow rates of water so 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. Push the plug(s) and/or
injectors firmly in place, replace the screen and hand tighten the injector cap.
Refill Flow Control Assembly or Refill Port Plug:
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 flat blade screwdriver.
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. Do not use petroleum jelly, oils, or other unaccept-
able lubricants on o-rings. A silicone lubricant may be used on the o-ring on the elbow or the white retainer.
Water Meter or Meter Plug:
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 discon-
nect the power source and water meter plugs from the PC board. Unlatch the drive assembly and lean if 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. If no water meter wire is visible, then a plug is installed, not a water meter. 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
Figure 7

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, gently pull forward on the turbine to remove it from the shaft.
Do not use a wire brush to clean the turbine. 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 bearing on the turbine are worn, replace the turbine.
Do not lubricate the turbine shaft. The turbine shaft bearings are prelubricated. Do not use petroleum jelly, oils, or other unacceptable lubricants on the o-ring. A
silicone 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.
Bypass Valve:
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 several times to ensure rotor is turning freely.
The nuts and caps are designed to be unscrewed or tightened by hand. 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. 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.
When reinstalling the red arrow handles be sure that:
1. The handle pointers are lined up with the control valve body arrows, and the rotor seal o-ring and the retainer on both rotors face to the right when being viewed
from the front of the control valve; or
2. Arrows point toward each other in the bypass position.
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. After completing and valve mainte-
nance, press and hold NEXT and REGEN buttons for 3 seconds or unplug power source jack (black wire) and plug back in. The resets the electronics and establishes
the service piston position. The display should flash all wording, then flash the software version (e.g. 181) and then reset the valve to the service position.
