SECTION 1: BEFORE INSTALLATION
When properly installed, operated, and maintained, your new water softener will provide years of dependable service. Before starting the installation, please
read this entire manual for an overview, and then follow the installation instructions. Failure to follow the instructions will void the warranty.
Inspecting And Handling Your Water Softener:
Inspect shipping carton and 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 or on its side to help prevent media from entering valve and being discharged downstream.
Make Sure Your Water Has Been Thoroughly Tested:
An analysis of your water should be made prior to the selection of your water softener. You can typically get this service through your place of purchase, which
may require sending 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
The test for Hydrogen sulfide (H2S) must be completed at the well site. For accuracy, the sample must be drawn with the pump RUNNING, and the test
be completed within ONE (1) minute after the sample is drawn.
Water softeners are designed to reduce hardness but can handle reasonable amounts of soluble iron if consideration is given to iron content when
selecting model and regeneration settings. To treat sulfur (hydrogen sulfide), bacterial iron, precipitated iron or very high levels of soluble iron special
equipment in addition to a water softener is required. For best results, an iron reduction system is recommended for use on waters containing more
than 2 ppm of iron.
1-1

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).
CAUTION
To reduce the risk associated with property damage due to water leakage:
•Do not install if water pressure exceeds 125 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 80 psi or more, nighttime pressure may exceed 125
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 is required to take appropriate measures if there is the possibility a vacuum condition 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 sucient for satisfactory operation and backwashing of the water softener. (See Specifications And Operat-
ing Data, Section 7).
IMPORTANT NOTES
If sediment is present, the installation of a sediment pre-filter is recommended. Even if sediment is not currently present or at a level high enough to be
objectionable, a pre-filter can help increase the eciency of the softener and help reduce the amount of maintenance required.
Installation Site Selection:
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 water softener in the supply line BEFORE the water heater. Temperatures above 110°F (43°C) will damage the water softener and void
the factory warranty.
5) DO NOT install the water softener in a location where freezing temperatures occur. Freezing may cause permanent damage and will also void the
factory warranty.
6) Allow sucient 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 40°F (4°C).
•Do not install on hot water supply lines. The maximum operating water temperature of this water softener is 110°F (43°C).
•Do not install systems in areas where ambient temperatures may go above 110°F (43.3°C) or below 40°F (4.4°C).
•Do not install in direct sunlight or outdoors.

Facts to Remember While Planning The Installation:
1) All installation procedures MUST conform to local and state plumbing codes.
2) Remember that the water softener INLET is attached to the pipe that supplies water (i.e. delivers water from the well pump or after the water meter)
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.
3) Before beginning the installation review 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 electrical system requires use of the cold water system as an electrical safety ground, a jumper must be used to ensure a sucient ground connection across
the water softener installation piping — refer installation to qualified personnel.
4) Sweep the floor to eliminate objects that could pierce the brine tank.
IMPORTANT NOTE
SODIUM INFORMATION: Water softeners using sodium chloride for regeneration add sodium to the water. People who are on sodium restricted diets
should consider the added sodium as part of their overall sodium intake.

Step 1) Remove unit from shipping box, inspect for damage and ensure all parts needed for installation are present. If parts are missing please contact
our customer service department for help @ 1-866-990-9785. Remove the packing from unit and discard according to local, state and federal
regulations. 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) Verify all packaging materials have been removed from the brine tank. On all units, legs rest on bottom of the brine tank. 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.
Step 3) Shut o all water at main supply valve. On a private well system, turn o power to the pump and drain the pressure tank. Make certain pressure is relieved
from the complete system by opening the faucet closest to the 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 o.
Step 4) Cut main supply line as required to fit plumbing to inlet and outlet of unit.
a. Locate the bypass valve assembly. Using the connection fittings attached to the bypass valve assembly, screw onto the existing threaded assembly on
the control valve, hand tighten only.
b. Ensure the bypass valve is placed into the bypass position as shown in Figure 2 until instructed to place into the service position.
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.
You will need to assemble the 1” NPT male connection fitting before you attach it to the bypass valve. Please refer to Figure 2 below to correctly
assemble the connection fitting. Attach the plumbing to the 1” NPT male connection fittings, hand tighten the fitting nuts only. Be careful not to
apply heat to any plastic part when making the connection of the plumbing to the connection fittings. Utilize only thread sealant tape to seal any
NPT fittings that connect to the connection fittings. Both NPT connections utilize an o-ring to prevent a leak.
Next connect the connection fittings to the bypass valve attached to the control valve. Be cautious not to over tighten the fittings as damage to
these items are not covered under the product warranty, and may cause water damage to your home or facility. Make certain the water enters
the inlet and discharges through the outlet sides of the bypass valve. Arrows on the bypass valve indicate water flow. Refer to SECTION 6: COM-
PONENT LIST AND ASSEMBLIES for an assembly drawing on the connector. Please Note: leave the bypass valve in the bypass position until you
are ready to regenerate the water softener. Attach the bypass to the control valve. Hand tighten the connections.
WARNING
To reduce the risk associated with a hazardous voltage:
• If the electrical system requires use of the cold water system as an electrical safety ground, a jumper must be used to ensure a sucient ground con-
nection across the water softener installation piping — refer installation to qualified personnel.
CAUTION
To reduce the risk associated with property damage due to water leakage:
•Do not apply heat to any fitting connected to bypass or control valve as damage may result to internal parts or connecting adapters.
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.
Fitting Installation Instructions
1. The installation fittings are designed to accommodate minor plumbing misalign-
ments, but are not designed to support the weight of a system or plumbing line
and fittings.
2. Thread tape is the only type of thread sealant allowed to be used; the use of paste
of any kind will void the factory warranty.
3. Slide the nut on first (closed and against the threads), then slip the split ring onto
the fitting, ensuring it set correctly in groove, then the o-ring last. Use Silicone
lubricant to allow for easier insertion of parts into one another.
4. Hand tighten the nut only, the use of pliers or wrenches of any type will void the
factory warranty and may cause an unexpected failure and water leak in your
home or facility.

Step 6) The control valve allows 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, the 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 your local pluming code prior to installation.
Step 8) Position the drain line over the drain and secure firmly. To prevent back-siphoning of sewer water, provide an air-gap of at least 2” or 2 pipe
diameters between end of drain hose and drain (Figure 4). DO NOT raise drain line more than 10 ft. above floor.
Step 9) Connect one end of the included 3/8” black polyethylene tubing to the brine fitting located on the left side of the control valve. Connect the other
end to the safety brine valve elbow 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 tub-
ing into the fitting elbow and hand tighten only. CAUTION: DO NOT use pliers or wrenches to tighten as damage may occur and will void the
manufacturer’s warranty.
Step 10) Install the overflow line to the brine tank overflow fitting (Figure 3). The overflow discharge must be lower than the overflow fitting. DO NOT connect
overflow line with valve drain line.
Step 11) Make certain the bypass valve inlet and outlet knobs are in “bypass” position. After all plumbing connections have been completed, open main
water shut-o valve and restore power to well pump. Check for leaks and correct as necessary.
Step 12) Plug the control valve power cord into 110v/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 adjust-
ment may be necessary when unusual operating conditions exist, such as high concentrations of iron, manganese or hardness and/or high flow
rates or daily water consumption.
Step 13) Manually set the control to backwash position. Press and hold the REGEN button for 3 seconds. The valve will advance to the backwash position. When
in position it will begin the cycle time count down. Unplug the power cord to prevent the unit from advancing automatically.

Step 14) Partially open the inlet knob on bypass valve (Figure 4). This
will allow the unit to fill slowly from the bottom up, reducing
air entrapment. Allow the unit to fill slowly, failure to do so
could result in loss of resin to the drain. Once a steady stream
of water, with no air sputtering, is flowing to the drain, the inlet
and outlet bypass knobs can be fully opened (refer to Figure 5).
Allow water to flow for 30 minutes.
Step 15) Plug the power cord back into the power source. Press the
REGEN button once and wait for the valve to advance to the
REGENERATE position indicated by the timer countdown. Press
the REGEN button again to advance to 2 BACKWASH indicated by
the timer countdown, press the REGEN button again to advance
to RINSE cycle.
Step 16) Unplug power cord to prevent the unit from advancing
automatically. Allow the water to flow to drain for 70 minutes.
Plug the power cord back into the power source and allow
the program to restart automatically and complete the normal
program. Allow brine tank to fill with the preset amount of
water. Note: brine tank will not completely fill with water. Unit is
ready for service when the Time shows on the display (Time of
Day will be on the display).
Step 17) Fill brine tank with salt.
Step 18) Refer to Section 3: Control Valve Programming and Regenera-
tion Instructions, on how to set control valve for proper set up
and regeneration settings.
SPECIAL SERVICE INSTRUCTIONS:
Under normal circumstances removal of the valve should not be required. However, if it must be removed, disconnect the plumbing attached to the by-
pass valve first. Then, rotate the valve head assembly to the left or counter-clockwise. Before attempting any disassembly, pressure should be relieved
by shutting o water to the system and opening a faucet. Upon reassembly, all o-rings should be lubricated with silicone grease. Reattach valve head
assembly by rotating to the right or clockwise until valve head assembly is seated to the tank hand tight. Reconnect the plumbing to the bypass valve.

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 im-
mediately. The request cannot be cancelled.
NOTE: For water softeners, 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 out-
ages or when daylight saving time begins or ends. If an extended power outage occurs,
the time of day will flash on and o 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 installed.
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.”
OR
REGEN TODAY will be
displayed if a regeneration
is expected “To night.”

SECTION 4: MAINTENANCE
Replenishment of Salt Supply:
The salt storage capacity of the brine tank is approximately 135 lbs. (61 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:
Most types of water softener salt may be used. There are advantages and disadvantages to every type of salt. Please ask your local dealer for advice. 3M
Purification does not recommend the use of block type salt.
Brine Tank Clean-Out:
To help prevent service problems the brine tank should be emptied and flushed out with a garden hose annually or when dirt and other insolubles accumulate.
The clean-out should be done when the salt level is low. Do not perform this clean-out procedure during regeneration cycle.
Steps to follow:
(1) Disconnect brine line at either end.
(2) Turn brine tank upside down and discard old salt.
(3) Remove the salt shelf and rinse both the tank and salt shelf with a garden hose.
(4) Reinstall salt shelf and reconnect brine line.
(5) Before loading salt, using a pail or garden hose, add enough water to the brine tank to cover the lower portion of the salt shelf. Then add salt to brine tank.
Add one (1) cup of unscented laundry bleach to the brine well to sanitize the system.
Iron-Fouling of Media Bed:
If iron is present in the water supply, the water softener media bed will eventually become iron-fouled, resulting in reduced softening capacity and rust-
stained fixtures. Mixing one to two ounces of Iron Reduction Media with every 80 lbs (36 kg). of salt added to brine tank will help minimize these problems
from occurring. Please contact your Dealer/Installer or our Customer Service Department at 1-866-990-9785 for additional information.
Periodically Check Time of Day Setting:
Power outages of eight hours or more 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 6, page 6-1 for additional information).
Change of Operating Conditions:
Should your water usage habits or your water quality change, the regeneration program settings may have to be adjusted. Please contact your Dealer/Installer
or our Customer Service Department at 1-866-990-9785 for additional information.
Special Service Instructions:
Under normal circumstances removal of the valve should not be required. However, if it must be removed, disconnect the plumbing attached to the bypass valve
first. Then, rotate the valve head assembly to the left or counter-clockwise. Before attempting any disassembly, pressure should be relieved by shutting o water to
the system and opening a faucet. Upon reassembly, all o-rings should be lubricated with silicone grease. Reattach valve head assembly by rotating to the right or
clockwise until valve head assembly is seated to the tank hand tight. Reconnect the plumbing to the bypass valve.

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 o 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 o 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 o 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 6 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
bisulfate 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.
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 aect 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 as-
sembly using a screwdriver as a ratchet until the black o-ring 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 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 into 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 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 o. 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 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 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
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 o, 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.
