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 12 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
• Be sure system and installation are in compliance with all state and local laws and regulations.
For the homeowner, please read operating displays and instructions.
WATER SOFTENERS:
During operation, the normal user displays are time of day or gallons remaining before regeneration
will occur.
Days remaining is an optional display but is not normally used. Each of these can be viewed by pressing
NEXT to scroll through them. When stepping through any displays or 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.

4
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 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
1. The distance between the drain and the water conditioner 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 conditioner with less than 10 feet of piping between its outlet and the inlet
of a water heater.
4. Do not position 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.
WELL WATER INSTALLATION MUNICIPAL INSTALLATION
INSTALLATION:

6
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 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 and state 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.
Typical Drain Line Installations

7
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 conditioner.
9. BRINE TANK CONNECTION: Install the 3/8" O.D. polyethylene tube from the Refill Elbow to the
Brine 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.

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. Pressing NEXT will exit SET CLOCK
and return to the general operating display (page 10).
1. Set time of day:
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: 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 – DAY OVERRIDE: The manufacturer has factory set 12 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 (12 is recommended):
• set number of days between regeneration (1 to 28); or
• set to “OFF”.
Press NEXT to go to step 4. Press REGEN if you need to return to the previous step.

GENERAL OPERATION DISPLAYS
REGENERATION
MODE
OPERATING DISPLAYS AND INSTRUCTIONS:
1. GENERAL OPERATION: When the system is operating,
one of three displays may be shown. Pressing NEXT will
alternate between the displays. One of the displays is always
the current time of day. The second display shows the current
treated water flow rate through the system in Gallons Per
Minute. The third display is one of the following: days
remaining or volume remaining. Days remaining is the
number of days left before the system goes through a
regeneration cycle. Capacity remaining is the gallons that
will be treated before the system goes through a regeneration
cycle. The user can scroll between the displays as desired.
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, the word “Softening” or “Filtering” flashes on the
display when water is being treated (i.e. water is flowing through the system).
2. REGENERATION MODE: Typically a system is set to regenerate at
a time of no water use. 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 that is less than 24 hours, the
control valve will remember all settings and time of day. After 24
hours, 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 that is less than 24 hours 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 14 for battery location).

5. ERROR MESSAGE: If the word “ERROR” and a number are
alternately flashing on the display record the number and contact
the dealer for help. This indicates that the control valve was not
able to function properly.
6. 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. 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: The manufacturer does not recommend the use of any
resin cleaners, nor placement of any resin cleaners into
the brine tank. This may be harmful to the water
softener and for human consumption. Consult dealer
for proper cleaning instructions.
ERROR

START-UP INSTRUCTIONS:
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. Wait two to three minutes or until water runs clear, then turn water off and follow
start-up instructions.
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.
12

13
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 9, Brine Tank Maintenance and 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.
7. CONDITIONING OF MEDIA:
To flush any remaining debris and air from the system again:
1. Full 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.
3. Turn on hot water and check for air, then turn water off after air is discharged.
8. SANITIZING OF UNIT UPON INSTALLATION AND AFTER SERVICE:
At this time, it is advised to sanitize the softener:
1. Open brine tank and remove brine well cover.
2. Pour 1 oz. of household bleach into the softener brine well.
3. Replace brine well cover.
NOTE: Avoid pouring bleach directly onto the safety float components in the brine well.
Unit sanitizing will be complete when the first cycle is run and the bleach is flushed from the softener.
9. Check time of day. Start-up is now complete.
