WARNING:
A copper or galvanized cold water pipe may be
used to ground electrical outlets in the home.
Failure to maintain this ground path may result
in an electric shock hazard. If the cold water pipe
is used to ground electric outlets, please refer to
Installing the Ground Wire section before cutting
the pipe.
Check and comply with your state and local
codes. You must follow these guidelines.
Use care when handling the water softening
system. Do not turn upside down, drop, drag or
set on sharp protrusions.
Water softening systems using sodium chloride
(salt) for recharge add sodium to the water.
Persons on sodium restricted diets should
consider the added sodium as part of their
overall intake. Potassium chloride can be used
as an alternative to sodium chloride in your
softener.
Use only lead-free solder and flux for all sweat-
solder connections, as required by state and
federal codes.
This water softening system must be properly
installed and located in accordance with the
installation instructions before it is used.
Keep the salt hole cover in place on the softener
unless servicing the unit or refilling with salt.
WARNING:Do not use with water
that is microbiologically unsafe or of unknown
quality without adequate disinfection before
or after the system.
WARNING:Discard all unused
parts and packaging material after
installation. Small parts remaining after the
installation could be a choke hazard.

The water softening system works on 24 volt-
60 Hz
electrical power only. Be sure to use the
included external power supply.
External power supply must be plugged into an
indoor 120 volt, grounded outlet only.
Use clean water softening salts only, at least
99.5% pure. NUGGET, PELLET or coarse SOLAR
salts are recommended. Do not use rock, block,
granulated or ice cream making salts. These
types of salts may contain dirt and sediments
that might mush or cake, creating maintenance
issues for the water softener.
Avoid installing in direct sunlight. Excessive
heat may cause distortion or other damage to
non-metallic parts.
If installing the water softener outdoors, do
not locate where it will be exposed to wet
weather, direct sunlight, extreme hot or cold
temperatures, or other forms of abuse.
WARNING! For your safety, the information in this manual must be followed to minimize
the risk of electric shock, property damage or personal injury.
In the state of California: You must turn the
Salt Efficiency Feature setting to ON. This may
initiate more frequent recharges. However it
will operate at 4,000 grains per pound of salt or
higher. To turn on the Salt Efficiency Feature,
follow the instructions in the “Salt Saver”
section of this manual
In the Commonwealth of Massachusetts,
Plumbing Code 248 CMR shall be adhered to.

**** Canada working pressure limits: 1.4–7.0 kg/cm2.
This model is efficiency rated. The efficiency rating is valid only at the minimum stated salt dose. The softener has a demand
initiated regeneration (D.I.R) feature that complies with specific performance specifications intended to minimize the amount
of regenerant brine and water used in its operation.
The softener has a rated salt efficiency of not less than 4,000 grains of total hardness exchange per pound of salt (based on
sodium chloride), and shall not deliver more salt than its listed rating or be operated at a sustained maximum service flow
rate greater than its listed rating. This softener has been proven to deliver soft water for at least ten continuous minutes at
the rated service flow rate. The rated salt efficiency is measured by laboratory test described in NSF/ANSI Standard 44. These
tests represent the maximum possible efficiency that the system can achieve. Operational efficiency is the actual efficiency
after the system has been installed. It is typically less than the efficiency, due to individual application factors including water
hardness, water usage, and other contaminants that reduce the softener’s capacity.

About the water softener system.
SERVICE
When the water softening system is providing
soft water, it is called “Service.” During service,
hard water flows from the house main water pipe
into the water softening system. Inside the water
softening system resin tank is a bed made up of
thousands of tiny, plastic resin beads. As hard
water passes through the bed, each bead attracts
and holds the hard minerals. This is called ion-
exchanging. It is much like a magnet attracting
and holding metals. Water without hard minerals
(soft water) flows from the water softening system
and to the house pipes.
After a period of time, the resin beads become
coated with hard minerals and they have to
be cleaned. This cleaning is called recharge.
Recharge is started at 2:00 AM (factory setting) by
the water softening system control, and consists
of five stages or cycles. These are FILL, BRINING,
BRINE RINSE, BACKWASH and FAST RINSE.
AUTOMATIC HARD WATER BYPASS DURING
RECHARGE
During recharge the water softener is
automatically put in bypass mode allowing hard
water to be available to the home. Once the
softener is recharged water is directed back
through the softener to be conditioned.
However, you should avoid using HOT water
because the water heater will fill with the hard
water.
FILL
Salt dissolved in water is called brine. Brine is
needed to clean the hard minerals from resin
beads. To make the brine, water flows into the salt
storage area during the fill stage.
BRINING
During brining, brine travels from the salt storage
area into the resin tank. Brine is the cleaning agent
needed to remove hard minerals from the resin
beads. The hard minerals and brine are discharged
to the drain.
The nozzle and venturi create a suction to move
the brine, maintaining a very slow rate to get the
best resin cleaning with the least salt.
BRINE RINSE
After a pre-measured amount of brine is used,
the brine valve closes. Water continues to flow in
the same path as during brining, except for the
discontinued brine flow. Hard minerals and brine
flush from the resin tank to the drain.
BACKWASH
During backwash, water travels up through
the resin tank at a fast flow rate, flushing
accumulated iron, dirt and sediments
from the resin bed and to the drain.
FAST RINSE
Backwash is followed by a fast flow of water down
through the resin tank. The fast flow flushes brine
from the bottom of the tank,
and packs the resin bed.
After fast rinse, the water softening system returns
to soft water service.

About the water softener system.
FEATURE: OPTIONAL RECHARGE CONTROLS
Sometimes, a manually started recharge may
be desired or needed. Two examples:
You have used more water than usual (house
guests, extra washing, etc.) and you may run
out of soft water before the next recharge.
The system ran out of salt.
Use one of the following features to start a
recharge immediately, or at the next preset
recharge start time.
RECHARGE TONIGHT
Touch (do not hold) the RECHARGE button.
RECHARGE TONIGHT flashes in the control display
area. A recharge will occur at the next preset
recharge start time. If you decide to cancel this
recharge, touch the same button once more.
RECHARGE NOW
Press and hold the RECHARGE button until
RECHARGE NOW starts to flash in the control
display area. The water softening system begins
an immediate recharge and, when over in about
two hours, you will have a new supply of soft
water. Once started, you cannot cancel this
recharge.
FEATURE: MEMORY
If electrical power to the water softening system is
interrupted, the control display is blank, and the blue
indicator light is off, but the control keeps correct
time for 24 hours. When power is restored, you have
to reset the present time only if the display and blue
indicator light are flashing. All other settings are
maintained and never require resetting unless a
change is desired.
If the time is flashing after a long power outage,
the water softening system continues to work as
it should to provide you with soft water. However,
recharge may occur at the wrong time of day until
you reset the control to the correct time
of day.
FEATURE/SERVICE: AUTOMATIC
ELECTRONIC DIAGNOSIS
The control computer has a self-diagnostic
function for the electrical system (except input
power and water meter). The computer monitors
the electronic components and circuits for correct
operation. If a malfunction occurs, an error code
appears in the control display.
NORMAL OPERATION, CONTROL DISPLAYS
During normal operation, the present time of
day and AM or PM and DAYS TO EMPTY show
in the control display area.
The system will automatically recharge at the
preset recharge time as needed.

About the water softener system.
WATER CONDITION INFORMATION
IRON
Iron in water can cause stains on clothing and
plumbing fixtures. It can negatively affect the
taste of food,drinking water, and other beverages.
Iron in water is measured in parts per million
(ppm). The total* ppm of iron, and type or types*,
is determined by chemical analysis. Four different
types of iron in water are:
Ferrous (clear water) iron
Ferric (red water) iron

Bacterial and organically bound iron
Colloidal and inorganically bound iron (ferrous
or ferric)
Ferrous (clear water) iron is soluble and dissolves
in water. This water softener will reduce
moderate amounts of this type of iron (see
specifications).**Ferrous (clear water) iron is
usually detected by taking a sample of water in
a clear bottle or glass. Immediately after taking,
the sample is clear. As the water sample stands,
it gradually clouds and turns slightly yellow or
brown as air oxidizes the iron. This usually occurs
in 15 to 30 minutes.
When using the softener to reduce Ferrous (clear
water) iron, add 5 grains to the hardness setting
fore very 1 ppm of Ferrous (clear water) iron. See
“Set Water Hardness Number” section.
Ferric (red water), and bacterial and organically
bound irons are insoluble. This water softener
will not remove ferric or bacterial iron. This iron
is visible immediately when drawn from a faucet
because it has oxidized before reaching the
home. It appears as small cloudy yellow, orange,
or reddish suspended particles. After the water
stands for a period of time,the particles settle to
the bottom of the container. Generally these irons
are removed from water by filtration. Chlorination
is also recommended for bacterial iron.
Colloidal and inorganically bound iron is of ferric
or ferrous form that will not filter or exchange
out of water. This water softener will not remove
colloidal iron. In some instances, treatment
may improve colloidal iron water. Colloidal iron
water usually has a yellow appearance when
drawn. After standing for several hours, the color
persists and the iron does not settle,but remains
suspended in the water.
SEDIMENT
Sediment is fine, foreign material particles
suspended in water. This water softener will not
remove sediment. This material is most often clay
or silt. Extreme amounts of sediment may give
the water a cloudy appearance. A sediment filter
installed upstream of the water softener normally
corrects this situation.
* Water may contain one or more of the four
types of iron and any combination of these. Total
iron is the sum of the contents.
** Capacity to reduce clear water iron is
substantiated by WQA test data.
CHLORINE
S oftener resins may degrade in the presence
of chlorine above 2 ppm. If you have chlorine
in excess of this amount, you may experience
reduced life of the resin. In these conditions, you
may wish to consider purchasing a GE point-of-
entry household filtration system with a chlorine
reducing filter.

Before you start.
BEFORE YOU START
The water softener requires a minimum water flow of 3 gallons per minute at the inlet. Maximum
allowable inlet water pressure is 125 psi. If daytime pressure is over 80 psi, nighttime pressure may
exceed the maximum. Use a pressure reducing valve if necessary (Adding a pressure reducing valve
may reduce the flow). If your home is equipped with a back flow preventer, an expansion tank must
be installed in accordance with local codes and laws.
The water softener uses a direct plug-in external power supply (included). Be sure to use the included
power supply and plug it into a nominal 120V, 60 cycle household outlet that is in a dry location only,
grounded and properly protected by an over current device such as a circuit breaker or fuse.

Do not use this system to treat water that is microbiologically unsafe or of unknown quality without
adequate disinfection upstream or downstream of the system.
INSPECT SHIPMENT
Make sure all the parts shown below are present. Additional parts must be purchased to complete the
installation. Thoroughly check the water softener for possible shipping damage and parts loss. Also
inspect and note any damage to the shipping carton.
Remove and discard (or recycle) all packing materials. To avoid loss of small parts, we suggest you keep the
small parts in the parts bag until you are ready to use them.

LOCATION REQUIREMENTS
Consider all of the following when selecting an
installation location for the water softener.
Do not locate the water softener where freezing
temperatures occur. Do not attempt to treat
water over 120ºF. Freezing temperatures or
hot water damage voids the warranty.
To condition all water in the home, install
the water softener close to the water supply
inlet, and upstream of all other plumbing
connections, except outside water pipes.
Outside faucets should remain on hard water to
avoid wasting conditioned water and salt.
A nearby drain is needed to carry away
regeneration discharge (drain) water. Use a
floor drain,laundry tub, sump, standpipe, or
other options(check your local codes). See
“Air Gap Requirements” and “Valve Drain
Requirements”sections.
The water softener uses a direct plug-in
external power supply (included). Be sure to
use the included power supply and plug it into
a nominal 120V, 60 cycle household outlet that
is in a dry location only, grounded and properly
protected by an over current device such as a
circuit breaker or fuse.
Always install the water softener between
the water inlet and water heater. Any other
installed water conditioning equipment should
be installed between the water inlet and water
softener (See Figure below).
If installing the water softener outdoors, do
not locate where it will be exposed to wet
weather, direct sunlight, extreme hot or cold
temperatures, or other forms of abuse.
DO NOT RUN HOT WATER THROUGH THE
SOFTENER. Temperature of water passing
through the softener must be less than 120° F.
Avoid installing in direct sunlight. Excessive sun
heat may cause distortion or other damage to
non-metallic parts.
When installing in an outside location you
must take steps necessary to assure the
softener, installation plumbing and wiring, are
protected from the elements, direct sunlight,
contaminantion, vandalism, insects, vermin, etc.
Do not install the softener where it would block
access to the water heater or access to the
main water shutoff.

PLUMBING CODES
All plumbing must be completed in accordance
with national, state and local plumbing codes.
In the state of Massachusetts: The Commonwealth
of Massachusetts plumbing code 248-CMR shall be
adhered to. A licensed plumber shall be used for
this installation.
AIR GAP REQUIREMENTS
A drain is needed for regeneration water (See
Figure 1). A floor drain, close to the water
softener, is preferred. A laundry tub, standpipe,
etc. are other drain options. Secure valve drain
hose in place. Leave an air gap of 1-1/2” between
the end of the hose and the drain. This gap is
needed to prevent back flow of sewer water into
the water softener. Do not put the end of the
drain hose into the drain.
VALVE DRAIN REQUIREMENTS
Using the flexible drain hose (included) (See Figure
2), measure and cut to the length needed. Flexible
drain hose is not allowed in all localities (check
your plumbing codes). If local codes do not allow
use of a flexible drain hose, a rigid valve drain run
must be used. Purchase a compression fitting (1/4
NPT x 1/2 in. minimum tube) and 1/2” tubing from
your local hardware store. Plumb a rigid drain as
needed (See Figure 3).
NOTE: Avoid drain hose runs longer than 30 feet.
Avoid elevating the hose more than 8 feet above
the floor. Make the valve drain line as short and
direct as possible.

Installation Instructions.
COMPLETE INLET AND OUTLET PLUMBING
WARNING:
A copper or galvanized cold water pipe may be
used to ground electrical outlets in the home. Failure
to maintain this ground path may result in an electric
shock hazard. If the cold water pipe is used to ground
electric outlets, please refer to Installing the Ground
Wire section before cutting the pipe.
IMPORTANT: This water softener has a non-
metallic valve system. Installing it on metal
plumbing will break electrical continuity, which
may interrupt grounding for the home. You
must restore electrical continuity in your metal
plumbing system.
If you install a 3-valve bypass system (Figure 5),
electrical continuity will be maintained. If you
install the non-metallic bypass valve (Figure 11),
please refer to the Installing the Ground Wire
section before cutting the pipe.
Measure, cut, and loosely assemble pipe and
fittings from the main water pipe to the inlet and
outlet ports of the water softener valve. Be sure
to keep fittings fully together, and pipes squared
and straight.
BE SURE INCOMING HARD WATER SUPPLY IS
DIRECTED TO THE SOFTENER VALVE INLET PORT.
NOTE: Inlet and outlet are marked on the water
softener valve. Trace the water flow direction to
be sure hard water is to inlet.
IMPORTANT: Be sure to fit, align and support
all plumbing to prevent putting stress on the
water softener valve inlet and outlet. Stress from
misaligned or unsupported plumbing may cause
damage to the valve.

INSTALLING THE GROUND WIRE
NOTE: If your house plumbing is plastic, it would
not be used as a grounding path, and this step
should be skipped.
IMPORTANT: A copper or galvanized cold water pipe
is often used to ground electrical outlets in the home.
Grounding protects you from electrical shock. The
water softener may have broken this ground path. To
restore connection, install a 12”-long, 6-gauge copper
wire across and tightly clamp using UL-approved
1/2”–1” bronze grounding clamps at both ends
as shown (Figure 12). Zinc clamps should not be
used on copper plumbing. Wire and clamps may
be purchased separately from your local hardware
store.
1. Clean copper pipe and ends of wire with emery
paper. Bare wire is recommended. If insulated

INSTALL VALVE DRAIN HOSE
1. Measure, cut to needed length and connect the
3/8”drain line (provided) to the water softener
valve drain fitting. Use a hose clamp to hold
the hose in place.
NOTE: Avoid drain hose runs longer than 30 feet.
Avoid elevating the hose more than 8 feet above
the floor. Make the valve drain line as short and
direct as possible.
IMPORTANT: If codes require a rigid drain line
see“Valve Drain requirements” section.
2. Route the drain hose or copper tubing to the
floor drain or other suitable drain point. Secure
drain hose. This will prevent “whipping’’ during
regenerations. See “Air Gap Requirements”
section (Figure 1).
NOTE: The softener will not work if the water
cannot exit the drain hose during recharge.
INSTALL BRINE TANK (SALT STORAGE)
OVERFlOW HOSE
1. Measure, cut to needed length and connect the
3/8”drain line (provided) to the salt storage tank
overflow elbow and secure in place with a hose
clamp.
2. Route the hose to the floor drain, or other
suitable drain point no higher than the drain
fitting on the salt storage tank (This is a gravity
drain). If the tank overfills with water, the
excess water flows to the drain point. Cut the
drain line to the desired length and route it
neatly out of the way.
IMPORTANT: For proper operation of the water
softener, do not connect the water softener valve
drain tubing to the salt storage tank overflow hose.
TEST FOR LEAKS
To prevent air pressure in the water softener and
plumbing system, complete the following steps in
order:
1. Fully open two or more softened cold water
faucets close to the water softener, located
down stream from the water softener.
2. Place the bypass valve (single or 3 valve) into
the”bypass” position. See Figures 4 and 5.
3. Slowly open the main water supply valve. Run
water until there is a steady flow from the
opened faucets, with no air bubbles.
4. Place bypass valve(s) in “service” or soft water
position as follows:

bypass valve and open the outlet valve.
Slowly open the inlet valve, pausing several
times to allow the water softener to fill with
water.
5. After about three minutes, open a hot water
faucet until there is a steady flow and there are
no air bubbles, then close this faucet.
6. Close all cold water faucets and check for leaks
at the plumbing connections that you made.
7. Check for leaks around clips at softener’s
inlet and outlet. If a leak occurs at a clip,
depressurize the plumbing (turn off the water
supply and open faucets) before removing clip.
When removing clips at the softener’s inlet
or outlet, push the single bypass valve body
toward the softener (See Figure 12). Improper
removal may damage clips. Do not reinstall
damaged clips.

ADD WATER AND SALT TO THE SALT
STORAGE TANK
WARNING!
EXCESSIVE WEIGHT HAZARD:
Use two or more people to move and lift
salt bags. Failure to do so can result in
back or other injuries.
1. Using a container, add about three gallons of
clean water into the salt storage tank.
2. Add salt to the storage tank. Use nugget,
pellet or coarse solar salts with less than 1%
impurities.
PLUG IN THE WATER SOFTENER
1. Plug the water softener into an electrical outlet
that is not controlled by a switch.
2. Replace the top cover.
3. Replace the salt hole cover.
NOTE: The water heater is filled with hard
water and,as hot water is used, it will refill
with conditioned water. In a few days, the hot
water will be fully conditioned. To have fully
conditioned hot water immediately, wait until
the initial recharge is over. Then, drain the water
heater(following instructions for water heater) until
water runs cold.
SANITIZE THE WATER SOFTENER /SANITIZE
AFTER SERVICE
1. Open salt hole cover, remove the brinewell cover
and pour about 3 oz. (6 tablespoons) of household
bleach into the softener brinewell. Replace the
brinewell cover.
2. Make sure the bypass valve(s) is in the
“service”(open) position.
3. Start a recharge (regeneration). See “Start a
Recharge”on Page 17.
4. After the recharge has completed, fully open a
cold water faucet, downstream from the softener,
and allow 50 gallons of water to pass through
the system. This should take at least 20 minutes.
Close the faucet.

1. Press the MODE/SET button until the arrow
points to HARDNESS. A flashing 25 will appear
in the display.
2. Press the UP or DOWN buttons to set
your water hardness number.
NOTE: If your water supply contains iron,
compensate for it by adding to the water
hardness number. For example, assume your
water is 20 gpg hard and contains 2 ppm iron.
Add 5 to the hardness number for each 1 ppm
or iron. In this example, you would use 30 for
your hardness number.
3. When the display shows your water hardness
(in grains per gallon), press MODE/SET to
accept.
You can get the grains per gallon (gpg)
hardness of your water supply from a water
analysis laboratory. If you are on a municipal
supply, call your local water department. Or
call Legend Technical Services, an independent
laboratory, to request a water hardness test
kit at 1.800.949.8220, Option 4. If your report
shows hardness in parts per million (ppm) or
milligrams per liter (mg/l), simply divide by 17.1
to get the equivalent number of grains per
gallon.

SET SALT LEVEL
1. Press the MODE/SET button until the arrow
points to SALT LEVEL.
2. Determine level of salt in brine tank using the
numbered scale on side of brine well, inside
brine tank (see Figure 13).
3. Press UP or DOWN button to set the
SALT LEVEL to correspond to level on the
numbered scale in brine tank.
NOTE: Each press of a button changes the
level by increments of 0.5 up to 8.0. Lowering
the salt level below zero turns the SALT LEVEL
indicator OFF.
4. Press the MODE/SET button to accept. The
display shows the present time of day and
DAYS TO EMPTY.
DAYS TO EMPTY
The words DAYS TO EMPTY and a number are
shown in the lower half of the display. This
information is shown in the normal run display.
This is to inform the user of the number of days
before the salt level in the brine tank reaches
Level 0. There will be salt left in the salt tank, but it
may not be sufficient to fully recharge the system.
Salt should be added at this time to avoid hard
water. The value is updated daily and whenever
the SALT LEVEL value is changed.
NOTE: For the first several weeks of operation, the
DAYS TO EMPTY may provide erratic operation.
For example, the blue indicator light may flash,
showing that more salt is required when the
actual salt level in the tank is well above the Level
0. In some cases, the DAYS TO EMPTY may even
increase over a several week period.
It takes a couple of months for the water softener
to learn your water usage pattern. Once it does
this, it will accurately determine actual salt usage
pattern. During this first period, check salt level
when blue indicator light flashes. If the salt level
in the tank is at Level 1 or above, allow system to
run. Be sure to reset your salt level indicator each
time you add salt to the system.
START A RECHARGE
Press the RECHARGE button and hold for three
seconds, until “RECHARGE NOW” begins to flash
in the display, starting a recharge. This recharge
draws the sanitizing bleach or brine into and
through the water softener. Any air remaining in
the water softener is purged to the drain. During
this time periodically check for leaks.
NOTE: As with all other water system
applications, leaks may occur. Leaks may not be
immediately apparent. Recheck 24 hours after
first recharge cycle is complete.

OPTIONAL CONTROL SETTINGS
The controller display has several options and
features.
LOW SALT ALARM
The LOW SALT ALARM,
when enabled, will
sound the beeper when
the DAYS TO EMPTY
value is 15 days or
less. To change this
setting, press and hold the MODE/SET button for
3 seconds or until you hear a beep. ON (factory
default) or OFF will flash in the display. Press
the UP or DOWN buttons to toggle this
feature ON or OFF. Press the MODE/SET button
to accept, and the display will move to SALT
EFFICIENCY.
SALT EFFICIENCY
When the SALT
EFFICIENCY feature is
ON, the unit will operate
at a salt efficiency of
4000 grains of hardness
removed per pound of
salt. This mode of operation is the most efficient
setting for salt usage, because the system will
tend to recharge more often, with less salt usage.
Turning the feature OFF will tend to lengthen the
time between recharge cycles, which will provide
the most efficient usage of water, but may use
more salt. The degree of difference between
these two cycles is highly dependent on the water
usage and hardness at a particular installation.
NOTE: California Regulations require this feature
to be ON for installations in California.
To access the Salt Efficiency, press and hold
the MODE/SET button for 3 seconds. The System
Diagnostics display will appear.
Press the MODE/SET button again and the Salt
Efficiency display will appear.
To change the setting, press the
UP or DOWN buttons to toggle the
feature ON or OFF. Press the MODE/SET button to
accept.
RESETTING TO FACTORY DEFAULT
To reset the electronic controller to its factory
default for all settings (time, hardness, etc.):
1. Press the MODE/SET button and hold until the
display changes twice to show the flashing
mode code.
2. Press the UP button to display a flashing
“SoS”.
3. Press the MODE/SET button and the electronic
controller will restart.
4. Set the present time, hardness, etc, as described
in the Programming the Water Softener section.

POWER OUTAGE MEMORY
If electrical power to the water softener is lost,
“memory’’ built into the timer circuitry will keep
all settings for up to 24 hours. While the power
is out, the display is blank and the water softener
will not regenerate. When electrical power is
restored, the following will occur:
Reset the present time only if the display is
flashing. The HARDNESS and RECHARGE TIME
never require resetting unless a change is desired.
Even if the clock is incorrect after a long power
outage, the softener operates as it should to keep
your water soft. However, regenerations may
occur at the wrong time of day until you reset the
clock to the correct time of day.
NOTE: If the water softener was regenerating
when power was lost, it will now finish the cycle.
BLUE INDICATOR LIGHT
Steady blue light indicates that the unit is working
correctly. The light flashes when the unit needs
attention from the user.

LOW SALT SIGNAL
When the DAYS TO EMPTY drops to 15, the blue
indicator light and DAYS TO EMPTY in the display
will flash every second and the alarm will beep
every 30 seconds (from 8:00 AM to 8:00 PM), to
notify the user that the unit is running low on
salt. As soon as any button is pressed, the alarm
will stop beeping. The blue indicator light and
DAYS TO EMPTY will continue to flash. Once salt
is added to the brine tank and the SALT LEVEL is
reset, the DAYS TO EMPTY will be reset.
ERROR SIGNALS
If there is an error code
detected, the blue
indicator light will flash
4 times every second,
the display will flash Err
and the alarm will beep
every 30 seconds (from
8:00 AM to 8:00 PM) to signal that the softener
requires service. The alarm can be turned off by
pressing any button, but the blue indicator light
and display will continue to flash.
Disconnect the transformer from the wall outlet
momentarily, and plug it back in. The normal
display will appear. The motor may run for several
minutes, as the unit resets. If the problem is
not corrected, the error code will reappear in
8 minutes. See the Before you Call for Service
section to assist in troubleshooting the water
softener.
