PRE-INSTALLATION INSTRUCTIONS FOR DEALERS
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, and time of regeneration,
before installation:
For the installer, the following must be used:
• Program Installer Settings ... Hardness, Day Override (preset to 6 days), and Time of Regeneration (preset to
2 a.m., with brine tank refill to occur four hours prior; see Operating Displays and Instructions for more details)
• Read Normal Operating Displays
• Set Time of Day
• Read Power Loss & Error Display
For the homeowner, please read operating displays and instructions.
WATER SOFTENERS:
During operation, the normal user display is time of day and gallons per minute.
Flow Rate, Capacity Remaining and Days to a Regeneration are optional displays but are not normally used. 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. If desired, two regenerations within 24 hours are possible with a return to the preset program. To do a
double regeneration:
1. Press the regen button once. “REGEN TODAY” will flash on the display.
2. Press and hold the regen button for three seconds until a regeneration begins.
Once the valve has completed the immediate regeneration, the valve will regenerate one more time at the preset.

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).

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, #CV3193-01. 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 – 30-100 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
WELL WATER INSTALLATION MUNICIPAL INSTALLATION
INSTALLATION
1. The distance between the drain and the water conditioner should be as short as possible.
2. Since salt must be added periodically to the brine tank, it should be in an easily accessible location.
3. It is NOT recommended to install any water conditioner with less than 10 feet of piping between its outlet and the inlet of
a water heater.
CAUTION: To protect the unit in the event of a hot water heater backup, the
manufacturer recommends the use of an expansion tank on the
outlet side of the unit.
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. 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 24-25. When assembling the installation fitting package (inlet
and outlet), connect the fitting to the plumbing system first and then attach the nut, split ring and “O” Ring. Heat from
soldering or solvent cements may damage the nut, split ring or “O” Ring. Solder joints should be cool and solvent cements

6 7
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”
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
with appropriate air gap (see drawing). Run drain tube to its discharge point in accordance with plumbing codes. Pay special
attention to codes for air gaps and anti-siphon devices.
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. SAFETY BRINE TANK CONNECTION: Install the 3/8” O.D. polyethylene tube from the Refill Elbow to the
Brine Safety Float valve in the brine tank.
10. OVERFLOW LINE CONNECTION: An overflow drain line is recommended where a brine overflow could
damage furnishings or the building structure. Your softener 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. Attach 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
“tie” 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. Allow an air gap as per the drain line instructions.

• After installation is complete, rotate bypass handles to bypass mode (see Fig.2 on page 4).
• Turn on water and check for leaks.
• Fully open a cold water faucet — preferably a laundry sink or bathtub without an aerator.
• 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 Manual or contact the manufacturer.)
1) BRINE TANK REFILL
2) 4 HOURS (240 minutes) OF SOFTENING MODE WHILE SALT IS DISSOLVING
3) BACKWASH
4) BRINE DRAW AND SLOW RINSE
5) FAST RINSE
6) END (return to service)
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 3” 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
reads “FILL” and the remaining time in this step is counting down. Since the regenerant tank was already filled in Step 1
press regen again and the display will read SOFTENING 240 (During a full regeneration this will be a 4 hour period
for salt to dissolve). Press regen again to put the valve into “BACKWASH.” Once valve has stopped in 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.
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 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. The bypass is now in the 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.
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. Restore power.
6. Place bypass valve in the normal operating mode (Fig. 1 on page 4) by opening the outlet bypass handle.
Press regen and the unit will return to the service position with time of day being displayed.

PROGRAMMING PROCEDURES
NOTE: The manufacturer has preset the unit so that the gallons between regenerations will be automatically calculated
after the hardness is entered.
STEP 1 – Press next and +simultaneously for 3 seconds.
STEP 2 – HARDNESS: Set the amount of hardness in grains per gallon (default 20) using the +or —buttons.
The allowable range is from 1 to 150 in 1 grain increments.
Note: If a resin media is used in the softener, increase the grains per gallon if soluble iron is present
(1ppm = 4 gpg). This display will show “–nA– (not available)” if “FILTER” is selected or if
“AUTO” is not factory set.
Press next to go to step 3. Press regen if you want to exit.
STEP 3 – DAYS BETWEEN REGENERATION (DAY OVERRIDE): The manufacturer has factory set 6 DAYS
as the default. This is the maximum number of days between regenerations. If this is set to “OFF”,
regeneration initiation is based solely on gallons used. If any number is set (allowable range from 1 to
28), a regeneration initiation will be called for on that day even if a sufficient number of gallons were
not used to call for a regeneration.
Set Day Override using +or —buttons (6 is recommended):
• set number of days between regeneration (1 to 28); or
• set to “OFF”
NOTE: This valve has the capability of regenerating up to six times in one
day. This can be observed by using the —button to toggle below once a day
regeneration (see example to right). These settings are typically used in twin
system configurations or in commercial settings.
Press next to go to step 4. Press regen if you need to return to the previous step.
2. Programming:
Time of day 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 indicating that the time should be reset.
STEP 1 – Press set clock.
STEP 2 – CURRENT TIME (HOUR): Set the hour of the day using +or —buttons. AM/PM toggles after 12.
Press next to go to step 3.
STEP 3 – CURRENT TIME (MINUTES): Set the minutes using +or —buttons. If it is desired to back up to the
previous step press regen button once. Press next to go to step 4.
STEP 4 – CURRENT DAY: Set the day of the week using +or —buttons. Pressing next will exit set clock and
return to the general operating display (page 10).
Example: Indicates unit set
to regen 4 times in one day.

10 11
STEP 4 – REGENERATION HOUR: The manufacturer has factory set 2:00 A.M.
as the default. This is the hour of day for regeneration and can be reset
by using +or —buttons. “AM/PM” toggles after 12. The default time is
2:00 a.m. (recommended for a normal household). Press next to go to
step 5. Press regen if you need to return to the previous step.
STEP 5 – REGENERATION MINUTES: Set the minutes using +or —buttons.
Press next to go to step 6. Press regen to return to previous step.
To initiate an immediate manual regeneration, press and hold the
regen button for three seconds. The system will begin to regenerate
immediately. The control may be manually stepped through the
regeneration cycles by pressing regen.
STEP 6 – ALARM BUZZER: The manufacturer has factory set “ON” as the
default. Alarm will sound immediately after regeneration if there is no salt
or if another error has occurred. Turn the alarm “OFF” or “ON” using
+or —buttons. Press next to exit installer programming.
STEP 7 – DISPLAY BACKLIGHT: The manufacturer has factory set “ON” as the
default. Turn the light “OFF” or “ON” using +or —buttons. “OFF”
will turn display backlight off after five minutes of keypad inactivity.
Press next to exit installer programming.

1. GENERAL OPERATION: When the system is operating, one of four displays may be shown. Pressing next will alternate
between the displays.
1. CURRENT TIME OF DAY and GPM
2. FLOW RATE which is the current treated water flow rate through the system in Gallons Per Minute
3. CAPACITY REMAINING which is the gallons that will be treated before the system signals a regeneration cycle
4. DAYS TO A REGEN is the number of days left before the system goes through a regeneration cycle, based on
the days override value

10 11

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.
If a water meter is installed, “GPM” flashes on the display when water is being treated, indicating gallons
per minute going through the system.
2. REGENERATION MODE: Typically a system is set to regenerate at a
time of no water usage. If there is a demand for water when the system is
regenerating, untreated water will be delivered. 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 provide treated water when the regeneration has been completed.
3. MANUAL REGENERATION: Sometimes there is a need to regenerate
before the control valve calls for it. This may be needed if a period of heavy
water use is anticipated or when the system has been operated without salt.
• To initiate a manual regeneration at the next preset regeneration time,
press and release regen. The words “REGEN TODAY” will flash
on the display to indicate that the system will regenerate at the next
regeneration time (set in Programming, steps 4 and 5). If you pressed
the regen button in error, pressing the button again will cancel the
command.
• 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 go into the FILL position. This position allows water to enter the brine
tank until it reaches the proper level. Once this position is complete, you will notice a 240 Minute (4 hours) SOFTENING
position. This 4-hour window allows the salt to dissolve and achieve proper brine strength. During these FILL and SOFTENING
positions, you will have softened water available for use. Once the unit advances to the BACKWASH position and
subsequent positions thereafter (see Start Up Instructions for regeneration sequence), the water softener will deliver water, but
it will be untreated.
IMPORTANT: With the Dry Salt Storage Feature, the brine tank will refill 4
hours before the actual regeneration occurs. You may experience a small amount
of noise for a short period of time at 10:00 p.m. (with typical setting) on the
night that regeneration is to occur. This noise is only the brine tank filling and at
no time during this process will you be without treated water.
4. POWER LOSS AND BATTERY REPLACEMENT: The AC 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).
5. CHECK SALT INDICATOR AND AUDIBLE ALARM: This control valve is 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 on the screen, 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.
6. ERROR MESSAGE: If the word “ERROR” and a number are alternately
flashing on the display record the number and contact your dealer for help.
This indicates that the control valve was not able to function properly.
7. 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.
Because “typical” settings of this water softener include a dry salt storage
feature (no water in brine tank between regeneration), 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. Do not use block salt. If pellet or rock salt is used, a
cleaning of the brine tank every six months is recommended. If the dry salt storage feature is not being utilized, block salt
may be used.
CAUTION: Do not use any resin cleaners, nor place 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.
