The manufacturer has preset the water treatment unit’s sequence of cycles, cycle times, salt dose, exchange capacity and
salt dose refill time.
The dealer should read this page and guide the installer regarding hardness, day override, time of regeneration,
service alarm and buzzer alarm settings before installation.
For the installer, the following must be used:
• Program Installer Settings: Time of Day and Hardness (manufacturer has set system to Immediate Regeneration;
see Operating Displays and Instructions for more details), Service Alarms (preset to “OFF”) and Buzzer Alarm
(preset to start at 6 a.m. and end at 10 p.m.)
• Read Normal Operating Displays
• Set Time of Day
• Read Power Loss & Error Display
• Be sure system and installation are in compliance with all state and local laws and regulations.
For the homeowner, please read Programming Procedures and Operating Displays and Instructions.
During operation, the normal user display is time of day and gallons per minute.
Flow Rate, Vacation Mode, Capacity Remaining and Days to a Regeneration are optional displays but are not normally
used. (Vacation Mode is used only when there will be no water usage for an extended period of time. Once 50 gallons
of water is used, the unit will automatically regenerate that night and resume normal operation.) Each of these can be
viewed by pressing next to scroll through them. When stepping through any programming, if no buttons are pressed
within 5 minutes, the display returns to a normal user display. Any changes made prior to the 5 minute time out are
incorporated. To quickly exit any Programming, Installer Settings, etc., press set clock. Any changes made prior to the
exit are incorporated.

The bypass valve is typically used to isolate the control valve from the plumbing system’s water pressure in order to perform control
valve repairs or maintenance. The 1” full flow bypass valve incorporates four positions, including a diagnostic position that allows
a service technician to have pressure to test a system while providing untreated bypass water to the building. Be sure to install
bypass valve onto main control valve, before beginning plumbing. Or, make provisions in the plumbing system for a bypass. 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 non-use. 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 direction of flow. 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 for normal operation of a water softener. During
the regeneration cycle this position provides regeneration water to the unit, while also providing untreated water to the
distribution system (Fig. 1).
2. BYPASS POSITION: The inlet and outlet handles point to the center of the bypass. The system is isolated from the water
pressure in the plumbing system. Untreated water is supplied to the building (Fig. 2).
3. DIAGNOSTIC POSITION: The inlet handle points toward the control valve and the outlet handle points to the center of
bypass valve. Untreated supply water is allowed to flow to the system and to the building, while not allowing water to exit
from the system to the building (Fig. 3). This allows the service technician to draw brine and perform other tests without the
test water going to the building.
NOTE: The system must be rinsed before returning the bypass valve to the normal position.
4. SHUT OFF POSITION: The inlet handle points to the center of the bypass valve and the outlet handle points away from
the control valve. The water is shut off to the building. The water treatment system will depressurize upon opening a tap in
the building. A negative pressure in the building combined with the softener being in regeneration could cause a siphoning
of brine into the building. If water is available on the outlet side of the softener, it is an indication of water bypassing the
system (Fig. 4) (i.e. a plumbing cross-connection somewhere in the building).

Installation
GENERAL INSTALLATION & SERVICE WARNINGS
The control valve, fittings and/or bypass are designed to accommodate minor plumbing misalignments. There is a small
amount of “give” to properly connect the piping, but the water softener is not designed to support the weight of the plumbing.
Do not use Vaseline, oils, other hydrocarbon lubricants or spray silicone anywhere. A silicone lubricant may be used on black
“O” Rings, but is not necessary. Avoid any type of lubricants, including silicone, on red or clear lip seals.
Do not use pipe dope or other sealants on threads. Teflon
®
tape must be used on the threads of the 1” NPT inlet and outlet, the
brine line connection at the control valve, and on the threads for the drain line connection. Teflon
®
tape is not used on the nut
connections or caps because “O” Ring seals are used. The nuts and caps are designed to be unscrewed or tightened by hand
or with the special plastic Service Wrench, #CV3193-02. If necessary pliers can be used to unscrew the nut or cap. Do not
use a pipe wrench to tighten nuts or caps. Do not place screwdriver in slots on caps and/or tap with a hammer.
SITE REQUIREMENTS
• water pressure – 25-100 psi • current draw is 0.5 amperes
• water temperature – 33-100°F (0.5-37.7°C) • the plug-in transformer is for dry locations only
• electrical – 115/120V, 60Hz uninterrupted outlet
• the tank should be on a firm level surface
1. The distance between the drain and the water softener should be as short as possible.
2. Since salt must be periodically added to the brine tank, it should be located where it is easily accessible.
3. Do not install any water softener with less than 10 feet of piping between its outlet and the inlet of a water heater.
4. Do not locate unit where it or its connections (including the drain and overflow lines) will ever be subjected to room
temperatures under 33°F.
5. Do not subject the tank to any vacuum, as this may cause an “implosion” and could result in leaking. If there is a possibility
a vacuum could occur, please make provision for a vacuum breaker in the installation.
6. INLET/OUTLET PLUMBING: Be sure to install Bypass Valve onto main control
valve before beginning plumbing. (See installation picture to right.
Be sure bypass is connected to treated water inlet
and outlet.) Make provisions to bypass outside hydrant and
cold hard water lines at this time. Install an inlet shutoff valve
and plumb to the unit’s bypass valve inlet located at the right
rear as you face the unit. There are a variety of installation
fittings available. They are listed under Installation Fitting
Assemblies, page 28-30. When assembling the installation
fitting package (inlet and outlet), connect the fitting to the

Installation
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 getting solder flux, primer, and solvent cement on any part of the “O” Rings, split rings, bypass valve or control valve.
If the building’s electrical system is grounded to the plumbing, install a copper grounding strap from the inlet to the outlet pipe.
Plumbing must be done in accordance with all applicable local codes.
7. INSTALLING GROUND: To maintain an electrical ground in metal plumbing of a home’s
cold water piping (such as a copper plumbing system), install a ground clamp or jumper
wiring. NOTE: If replacing an existing softener, also replace the ground clamps/wire. If
removing a softener, replace the piping with the same type of piping as the original to
assure plumbing integrity and grounding.
8. DRAIN LINE: First, be sure that the drain can handle the backwash rate of the system.
Solder joints near the drain must be done prior to connecting the drain line flow control
fitting. Leave at least 6” between the drain line flow control fitting and solder joints. Failure
to do this could cause interior damage to the flow control. Install a 1/2” I.D. flexible plastic
tube to the Drain Line Assembly or discard the tubing nut and use the 3/4” NPT fitting
for rigid pipe (recommended). If the backwash rate is greater than 7 gpm, use a 3/4” rigid drain line. Where
the drain line is elevated but empties into a drain below the level of the control valve, form a 7” loop at the discharge end
of the line so that the bottom of the loop is level with the drain connection on the control valve. This will provide an adequate
anti-siphon trap. Piping the drain line overhead <10 ft is normally not a problem. Be sure adequate pressure is available (40-
60 psi is recommended). Where the drain empties into an overhead sewer line, a sink-type trap must be used. Run drain tube
to its discharge point in accordance with plumbing codes. Pay special attention to codes for air gaps and anti-siphon devices.
NOTE: Drain line nut will not be supplied for units having a backwash rate greater than 7 gpm.
CAUTION: Never insert a drain line into a drain, sewer line, or trap. Always allow an air gap of 1-1/2” or twice the
pipe diameter, whichever is greater, between the drain line and the wastewater to prevent the possibility of
sewage being back-siphoned into the softener.

9. BRINE TANK ASSEMBLY: Brine tank components for 19x37” tanks need to be assembled in the field. Follow the steps below:
a. OVERFLOW ELBOW — Screw the
overflow elbow clockwise into the
hole below the brine well slots. The
elbow is self-tapping and does
not require a nut to be secured. Push
against the inside of the tank while
installing the elbow for leverage if
needed (Fig. 5).
b. BRINE WELL — Install the brine
well by aligning the arms into the
slots on the side of the tank with the
tabs facing outward (Fig. 6).
Continued on next page.
Self-tapping elbow does not require nut.
FIGURE 5
Brine well arms should line up with tank slots.

10. OVERFLOW LINE CONNECTION: An
overflow drain line is recommended where a
brine overflow could damage furnishings or
the building structure. Your unit is equipped
with a brine tank safety float which greatly
reduces the chance of an accidental brine
overflow. In the event of a malfunction,
however, an overflow line connection will
direct the “overflow” to the drain instead
of spilling on the floor where it could cause
considerable damage. This fitting is an elbow
on the side of the brine tank, which was
installed in Step 10-a. Finish the setup by attaching a length of 1/2” I.D. tubing to fitting and run to drain. Do not elevate overflow line
higher than 3” below bottom of overflow fitting. Do not connect this tube into the drain line of the control valve. Overflow line must be
a direct, separate line from overflow fitting to drain, sewer, or tub. The overflow line is a gravity drain and cannot run higher than the
initial drain point. Allow an air gap as per the drain line instructions.
11. SAFETY BRINE TANK CONNECTION: Install the 3/8” O.D. polyethylene tube
from the Brine Safety Float valve in the tank to the Refill Elbow on the control valve
(Fig. 13).
12. OVERFLOW LINE CONNECTION: An overflow drain line is recommended where a
brine overflow could damage furnishings or the building structure. Your unit is equipped
with a brine tank safety float which greatly reduces the chance of an accidental brine
overflow. In the event of a malfunction, however, an overflow line connection will
direct the “overflow” to the drain instead of spilling on the floor where it could cause
considerable damage. This fitting is an elbow on the side of the brine tank, which
was installed in Step 10-a. Finish the setup by attaching a length of 1/2” I.D. tubing
to fitting and run to drain. Do not elevate overflow line higher than 3” below bottom
of overflow fitting. Do not connect this tube into the drain line of the control valve.
Overflow line must be a direct, separate line from overflow fitting to drain, sewer, or
tub. The overflow line is a gravity drain and cannot run higher than the initial drain
point. Allow an air gap as per the drain line instructions.
c. BRINE WELL — Ensure the brine well
is properly secured on the bottom of
the tank (Fig. 7).
d. BRINE LINE — Push the brine line
into the flow control elbow of the
safety float assembly until it locks it
into place (Fig. 8).
e. BRINE WELL RETAINER — Install
the brine well retainer above the
brine well by pushing the retainer
down with the tabs facing outward.
Ensure the retainer is flush with the
tank and pushed all the way down
(Fig. 9).
f. BRINE WELL COVER — Snap the
cover over the brine well (Fig. 10).
g. BRINE TANK COVER — Install the
tank cover by aligning the arrows on
the outer edge of the cover with the
indents on the lip of the brine tank
(Fig. 11). Rotate the cover clockwise
1.5” to lock it into place (Fig. 12).
NOTE: The brine tank cover is found
inside the top of the box in the unit
packaging.
Push retainer all the way down onto tank.

1. GENERAL OPERATION: When the system is operating, one of five displays may be shown and will alternate with the
installing dealer’s name and phone number (if set) for future service. Pressing next will alternate between the displays.
1. CURRENT TIME OF DAY and GPM. Letter indicates which tank is in service. GPM alternates with current flow rate.
2. FLOW RATE which is the current treated water flow rate through either tank A or B in Gallons Per Minute.
3. VACATION MODE allows the system to be “shut down” when there will be no water usage for an extended
period of time.
4. CAPACITY REMAINING for the tank in service (A or B) and the gallons that will be treated before the system
signals a regeneration cycle and switches to the other tank. GPM alternates with current flow rate.
5. DAYS TO A REGEN is the number of days left before the system goes through a regeneration cycle, based on the
days override value. Letter indicates which tank is in service. GPM alternates with current flow rate.
6. DEALER NAME AND PHONE NUMBER is the dealer information to call when service is needed (this screen will
only appear if set by dealer).
The user can scroll between the displays as desired.
2. VACATION MODE: This feature may be used to “shut down” the system while on vacation. The manufacturer has
factory set “OFF” as the default. Turn feature “OFF” or “ON” using the + or — buttons. When turned “ON”, the
unit will not regenerate while there is no water usage. Once water usage is observed (minimum of 50 gallons), the
unit will automatically regenerate that night and resume normal operation.
CAUTION: Depending on the severity of water conditions and the length of no water
usage, it may not be recommended to use this feature. Please contact
dealer or manufacturer for more information.
3. MANUAL REGENERATION: Sometimes there is a need to regenerate before the control valve calls for it. This
may be needed if the system has been operated without salt for an extended period of time. To initiate a manual
regeneration immediately, press and hold the regen button for three seconds. The system will begin to regenerate
immediately. This command cannot be cancelled.
Once a manual regeneration is initiated, the unit will transfer to the second tank in order to supply conditioned
water. Upon transfer, the depleted tank will begin its regeneration.
4. REGENERATION MODE: Typically a twin system regenerates when the capacity
of the tank providing treated water reaches zero remaining gallons. At this time, the
online tank will transfer and put the standby tank online so there is no disruption
of treated water. Once this transfer is complete, the depleted tank will regenerate
and return to standby mode ready to enter service upon depletion of capacity of
other tank. This two tank configuration provides for a continuous, uninterrupted
supply of conditioned water at all times. 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 will run through all remaining steps automatically and will reset to provide treated water when the
regeneration process has been completed.

5. POWER LOSS AND BATTERY REPLACEMENT: The transformer comes with a
15 foot power cord and is designed for use with the control valve; the transformer
should only be used in a dry location.
In the event of a power outage, the control valve will remember all settings and
time of day. If an extended power outage occurs, the control valve will keep time
of day until the battery is depleted. When the battery becomes depleted, the only
item that needs to be reset is the time of day and will be indicated by the time of
day flashing. All other settings are permanently stored in the nonvolatile memory.
If a power loss occurs and the time of day flashes, this indicates that the battery
is depleted. The time of day should be reset and the non-rechargeable battery
should be replaced. The battery is a 3 Volt Lithium Coin Cell type 2032 and is
readily available at most stores. To access battery location, remove front cover
(see diagram on page 18 for battery location).
6. CHECK SALT INDICATOR AND AUDIBLE ALARM (OPTIONAL): This control valve may be equipped with a Low
Salt Warning to alert homeowners that the system is operating in a low salt condition. This usually indicates that the salt
level in the brine tank is too low to operate properly. If “CHECK SALT” appears, there will usually be an audible alarm
that sounds also (if turned on), alerting you to these conditions.
To turn off alarm: If the audible alarm sounds due to a low salt condition, press any button on the face of the
control valve to turn off. If salt is not added to the brine tank before the next regeneration,
the CHECK SALT indicator will alarm again.
IMPORTANT: If you feel that the salt level is adequate (at least 1/3 full) in the brine tank, please contact the dealer
that installed your system for service.
7. ERROR MESSAGE: If the word “ERROR” appears and flashes alternately with
the dealer name and phone number, record the ERROR number and your contact
servicing dealer promptly. This indicates that the control valve was not able to
function properly.
8. BRINE TANK MAINTENANCE AND SALT: Refill the brine tank as necessary,
making sure at least 1/3 of the brine tank is full at all times. Without proper salt
levels, the water softener may not operate properly.
The manufacturer recommends the use of solar salt for best results. The brine tank is manufactured for the use of
solar, pellets or rock salt. If pellet or rock salt is used, a cleaning of the brine tank every six months is recommended.
CAUTION: With some models the manufacturer does NOT recommend the use of
any resin cleaners, nor placing any resin cleaners into the brine tank.
Furthermore, do not use any salt that indicates it is an iron cleaning salt
or that contains any cleaning additives. This may be harmful to the water
softener and for human consumption. Consult dealer for proper cleaning
instructions and agents.

FLUSHING OF SYSTEM:
To flush the system of any debris and air after installation is complete, please perform the following steps:
1. Rotate bypass handles to the bypass mode (see Fig. 2 of page 4).
2. Turn on inlet water and check for leaks in the newly installed plumbing.
3. Fully open a cold water faucet, preferable at a laundry sink or bathtub without an aerator.
4. Allow water to run until clear to rid pipes of debris which may have occurred during installation.
System regeneration sequence is in the following order. (If it is desired to change this sequence, please refer to the Dealer
Master Programming Guide or contact the manufacturer.)
1) BACKWASH 4) BRINE TANK FILL
2) BRINE and RINSE DOWN 5) END (returns to Standby)
3) RAPID RINSE The system is now ready for filling with water and for testing.
1. With the softener in the bypass mode (Fig. 2 on page 4) and the control valve in normal operation where the display
shows either the time of day or the gallons remaining, manually add 8” of water to the regenerant tank.
NOTE: If too much water is put into the brine tank during softener start up, it could result in a “salty water” complaint after
the first regeneration.
During the first regeneration the unit will draw out the initial volume of brine/regenerant and refill it with the correct preset amount.
2. With the softener in bypass mode, press and hold the regen button until the motor starts. Release button. The display will read
“Pend 0” for about three seconds while the system transfers from one tank to another. After the transfer is complete, the valve will
automatically advance to the “Backwash” position. Once the valve has stopped in this position, unplug the transformer so that
the valve will not cycle to the next position. Open the inlet handle of the bypass valve very slightly, allowing water to fill the tank
slowly in order to expel air from the tank.
CAUTION: If water flows too rapidly, there will be a loss of media to the drain.
3. When the water is flowing steadily to the drain, clear and without the presence of air, slowly open the inlet valve. Restore
power and momentarily press the regen button to advance the control to the “BRINE” position.
4. With the bypass now in diagnostic mode (Fig. 3 on page 4), check to verify that water is being drawn from regenerant tank
with no air leaks or bubbles in the brine line. There should be a slow flow to the drain. Disconnect brine line from the safety float
valve in the brine tank and check for a vacuum. After proper confirmation, reconnect brine line, making sure to tighten securely.
5. Momentarily press regen again until the display reads “RINSE.” There should be a rapid flow to the drain. Unplug transformer
to keep the valve in the “RINSE” position. Allow to run until steady, clear and without air. While the unit is rinsing, load the
brine tank with water softener salt (refer to page 10, Brine Tank Maintenance and Salt). Restore power.
6. Push regen again and the unit will advance to the “Brine Refill” position. Check to make sure the brine tank is refilling.
The flow rate is usually .5 gpm for all residential and light commercial applications.
7. Push next and the unit will return to normal operation.
8. Place unit into bypass mode again (see Fig. 2 on page 4) and press and hold the regen button to allow control valve to
transfer to the second tank. Follow steps 2-7 to now expel air from this tank.
9. When finished expelling air from second tank, return bypass handles to normal operating position (see Fig. 1 on page 4).
The unit is now online and soft water is available for use.
10. CONDITIONING OF MEDIA (To flush any remaining debris and air from the system):
1. Fully open a cold water faucet, preferably at a laundry sink or bathtub without an aerator.
2. Wait two to three minutes or until water runs clear, then turn water off.

Release locking tabs
from each side to
remove back plate.
TRANSFER CAP ASSEMBLIES SERVICE INSTRUCTIONS
1. The backplate of the control valve must
first be removed to allow access to the
transfer cap assembly.
2. Hold slight downward pressure on the
top left corner of the backplate while
using a thin flat screwdriver or knife
blade to push in on the locking tabs.
This will release the backplate and it
will twist to the left of the valve body.
3. For removal of the drive motor side
(Fig. 3), remove the drive cover
assembly to access the motorized drive.
The drive motor can be removed by
pressing the spring clip loop to the right
then rotating the motor a quarter turn.
Pull outward to remove the motor from
the reducing gear cover assembly.
4. Remove the three Phillips head stainless
steel screws that retain the reducing
gear cover to the drive cap.
5. Once the cover is removed, there will be access to the reducing drive gears. Simply slide them off of the gear axles, then
inspect and check them (there are three small black gears with foil decals and one larger black reducing gear).
6. Remove the large white drive gear from the stainless steel drive shaft. To remove the large white transfer drive gear, firmly
grab the outside edge of the gear and pull it outward away from the control valve assembly.
7. Use a 5/32" or 4mm allen wrench to remove the ¼-#20 screws (six screws on each side) that retain the transfer drive cap
assemblies on both sides of the valve.
8. Once the screws are removed from retaining the inlet side transfer valve cap and the outlet drive motor transfer cap from the
control valve, the cap will spring out away from the valve body. At this point the transfer discs may be removed by pulling
the discs outward off of the shaft away from the valve body. With the disc out, inspect the flat surface area to be sure it is
clean, smooth and free of any debris or scratches. Note that the disc is keyed to the drive shaft so that it will only assemble
in one orientation. (See parts diagram on page 20.)
9. The transfer discs may be chemically cleaned with a dilute sodium bisulfate
solution (Iron Out), vinegar or just wiped with a soft clean cloth.
10. To remove seals, gently pull out on the outer lip of the seal to lift the seal out from
its cavity being careful not to damage the face surface of the seal.
11. To reassemble, reseat seals into the seal cavity of the control valve body being
sure that the lip of the seal is facing outward. See Fig. 2.
12. With seals in place, put a thin film of Dow #7 silicone grease on the tops of
the seals and the flat surface of the discs.
CAUTION: Do not use Vaseline, petroleum jelly or any other hydrocarbon lubricants on
plastic components or O-rings as they will cause damage to the material and
can potentially cause leaks in the system.
13. Prior to reinstalling the discs, the drive shaft should be removed and the O-rings cleaned, inspected and lubricated with
Dow #7 silicone grease. The shaft can now be installed into the disc prior to installation.
FIGURE 1
FIGURE 2
Transfer Cap Assembly Service

14. With the outlet disc assembled to the shaft, the orientation of the shaft to inlet disc can be assured by installing the set
with the through hole on the outlet disc at the 6 o’clock position. The easiest way to reassemble is to remove both disc
drives and assemble the outlet side first. Then each disc can be fitted on the shaft individually. At this point the transfer
valve cap assemblies can be reinstalled.
NOTE: Both transfer caps only mount in one orientation. Prior to installation of cap assembly, be sure to check that the
stainless steel spring and the plastic spring support is in place and attached to the inside of the assembly.
15. Wipe the outside edge of the O-ring on the cap and the inside mating area of the valve with a clean cloth and reapply
a thin layer of Dow #7 silicone grease.
16. Noting the one possible orientation of the transfer drive cap, use
one hand to press in and support the transfer drive cap while
using the opposing hand to start two screws in, one on the top
and one opposing it on the bottom. Tighten the screws evenly
so that the cap seats the O-ring without getting pinched or
damaged. Screws should only be hand tightened with a 5/32”
or 4mm allen wrench. DO NOT OVER TIGHTEN SCREWS.
NOTE: Take care to be certain the meter cable doesn’t
get under the drive cap while tightening as it will result in
damaging the cable.
17. Position the large white drive gear with the “A”
pointing toward the one o’clock position and
then press it onto the stainless steel drive shaft,
making sure it snaps and locks into position.
NOTE: The white drive gear is splined to the drive
shaft and will only assemble in one orientation.
Because of this, it is not necessary that the discs and
gear be exactly positioned. The positioning needs to
be approximate but they have to fit on the shaft.
18. Install the larger black reducing gear onto the stainless
steel shaft, then install the remaining smaller reducing
gears from left to right.
19. Reinstall the grey reducing gear cover over the gears and
affix with the three stainless steel screws.
20. Reinstall the drive motor by pressing the spring clip loop to the
right, then rotate the motor as you are inserting it so the gear
of the motor meshes properly with the reducing gears.
21. Release the spring clip loop and rotate the motor until the motor housing engages with the plastic nub inside the housing
that holds the motor in place, making sure that the top of the motor is flush with the top of the grey gear housing.
22. Press the drive motor wires down into the strain relief of the drive cap.
23. Reinstall the cover assembly.
After completing any valve maintenance involving the valve drive assembly or the transfer drive assembly, press and hold
the next and regen buttons simultaneously for three to five seconds to perform a soft reset which will synchronize the control
valves positions.
