Water Softening
System
System tested and certified by NSF International against NSF/ANSI Standard 44 for the
chemical reduction claims specified on the performance data sheet.
IMPORTANT SAFETY INFORMATION.
READ ALL INSTRUCTIONS BEFORE USING.
SAFETY PRECAUTIONS
■ 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.
■
The water softening system works on 24 volt-60 Hz
electrical power only. Be sure to use only the
included transformer.
■ Transformer 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. They contain dirt and
sediments, or mush and cake, and will create
maintenance problems.
■ 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.
READ AND FOLLOW THIS SAFETY INFORMATION CAREFULLY.
SAVE THESE INSTRUCTIONS
PROPER INSTALLATION
■ Install or store where it will not be exposed to
temperatures below freezing or exposed to any
type of weather. Water freezing in the system will
break it. Do not attempt to treat water over 100°F.
■ Do not install in direct sunlight. Excessive sun or
heat may cause distortion or other damage to
non-metallic parts.
■ Properly ground to conform with all governing
codes and ordinances.
■ Use only lead-free solder and flux for all
sweat-solder connections, as required by
state and federal codes.
■
The water softening system requires a minimum
water flow of three 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 to reduce the flow if necessary.
■
Softener 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.
WARNING: Discard all unused parts
and packaging material after installation. Small
parts remaining after the installation could be
a choke hazard.
This water softening system must be properly installed and located in accordance with the
Installation Instructions before it is used.

UNPACKING AND INSPECTION
Be sure to check the entire softener for any
shipping damage or parts loss. Also note damage
to the shipping cartons. Contact the transportation
company for all damage and loss claims. The
manufacturer is not responsible for damages
in transit.
Small parts needed to install the softener are
packaged either in a bag or on a cardboard
sheet. To avoid loss of the small parts, keep them
packaged until you are ready to use them. Be sure
not to discard components hidden in packaging.
TOOLS AND MATERIALS REQUIRED
FOR INSTALLATION
• Pliers
• Screwdriver
• Teflon tape
• Razor knife
• Two adjustable wrenches
• Additional tools may be required if modification
to home plumbing is necessary.
• In and out fittings included with the softener are
1″ NPT male adapters. You should maintain the
same, or larger, pipe size as the water supply
pipe, up to the softener inlet and outlet. Then,
use the necessary adapters to connect the water
supply to the 1″ NPT male adapters.
• Use the included bypass valve to install the
softener. The bypass valve allows you to turn off
water to the softener for servicing, but still have
water in the house pipes. The in and out fittings
referred to above connect to the bypass valve
with the included bypass clips.
• Use appropriate fitting/pipe material (i.e., copper,
brass, galvanized or CPVC) to connect the 1″ NTP
plastic adapters to the house plumbing.
• If additional drain hose is needed for valve and
salt tank drains, it can be ordered from GE Parts
at 800.626.2002, part number WS07X10004.
• If a rigid valve drain is needed to comply with
plumbing codes, you can buy the parts needed
to connect a 1/2″ copper tubing or plastic pipe
drain. See Step 5.
• Clean nugget or pellet water softener salt is
needed to fill the brine tank. See Step 11.
WHERE TO INSTALL THE SOFTENER
• Place the softener as close as possible to a
sewer drain, or other acceptable drain point
or standpipe.
• It is recommended to keep outside faucets
on hard water to save soft water and salt.
• Do not install the softener in a place where it
could freeze. Freeze damage is not covered by
the warranty.
• Do not install the softener where it would block
access to the water heater or access to the main
water shutoff.
• Put the softener in a place where water damage
is least likely to occur if a leak develops. The
manufacturer will not repair or pay for water
damage.
• A 120-volt electric outlet is needed to plug in the
included transformer. The softener has a 10-foot
power cable. If the outlet is remote (up to 100
feet), use 18 gauge wire to connect. Be sure the
electric outlet and transformer are in an inside
location, to protect from wet weather. Be sure
the outlet is unswitched to prevent accidental
shutoff.
• If installing in an outside location, you must
take the steps necessary to assure the softener,
installation plumbing, wiring, etc., are as well
protected from the elements (sunlight, rain, wind,
heat, cold), contamination, vandalism, etc., as
when installed indoors. Outdoor installation is
not recommended, and voids the warranty.
• Keep the softener out of direct sunlight.
The sun’s heat may distort non-metallic
parts and may damage the electronics.
Installation Instructions
PLAN HOW YOU WILL INSTALL THE
SOFTENER
You must first decide how to run in and out pipes
to the softener. Look at the house main water pipe
at the point where you will connect the softener.
Is the pipe soldered copper, glued plastic or
threaded galvanized? What is the pipe size?
WARNING: Use only lead-free solder and
flux to prevent lead poisoning.
See Typical Installation Illustration. Use this as a guide
when planning your particular installation. Be sure
to direct the incoming hard water supply to the
softener valve inlet fitting. The valve is marked
IN and OUT.

CAUTION:
• Secure the resin tank to a stable structure to
prevent it from falling over.
• Locate the brine tank directly next to the resin
tank.
• Be sure the installation surface is level and
smooth. Sharp objects under the brine tank may
puncture it. If needed, place the brine tank on a
section of 3/4″ thick (minimum) plywood. Then,
place shims under the plywood as needed to
level the softener.
• Connect the black brine valve tube from the
brinewell to the venturi assembly on the valve,
using the plastic nut provided.
3
PLUMB “IN” AND “OUT” PIPES
TO AND FROM SOFTENER
CAUTION: Observe all of the following
cautions as you connect inlet and outlet
plumbing. See Typical Installation Illustration.
• BE SURE INCOMING HARD WATER SUPPLY IS
DIRECTED TO THE SOFTENER VALVE INLET PORT.
If house water flow is from the left, use a
plumbing crossover as shown in Typical
Installation Illustration. If house water flows up
from the floor level, turn the bypass valve upside
down as shown.
• With the softener in place, determine the correct
length of piping required to connect the household
plumbing to the NPT male adapter.
• Remove softener from installation space.
• If making a soldered copper installation, do all
sweat soldering before connecting pipes to the
NPT adapters and bypass valve. Torch heat will
damage plastic parts.
• When turning threaded pipe fittings onto plastic
fittings, use care not to cross-thread.
• Use Teflon Tape on all external pipe threads.
• Support inlet and outlet plumbing in some manner
(use pipe hangers) to keep the weight off of the
valve fittings.
• Slide softener back into position.
• Make final connections to the bypass valve and
snap clips into place.
Be sure the clips for the bypass valve and NPT
adapters snap into place. Pull on the bypass valve
and NPT adapters to make sure the parts are held

CONNECT AND RUN THE VALVE
DRAIN HOSE
IMPORTANT: If you want to attach the drain fitting
to a rigid tube, see Connecting a Rigid Valve Drain
Tube section on next page.
• Use the provided drain hose (20′ length included)
to attach to the valve drain fitting. To keep water
pressure from blowing the hose off, use supplied
spring clamp to secure in place. Cut the necessary
length and use the remainder in Step 8.
• Locate the other end of the hose at a suitable
drain point (floor drain, sump, laundry tub, etc.)
that terminates at the sewer. Check and comply
with local codes.
IMPORTANT: If more drain hose is needed, it
should be ordered from GE Parts at 800.626.2002,
part number WS07X10004. The water softener will
not work if water cannot exit this hose during
recharge.
• Tie or wire the hose in place at the drain point.
High water pressure will cause it to whip during
the back-wash and fast rinse cycles of recharge.
Also provide an air gap of at least 1-1/2″
between the end of the hose and the drain
point. An air gap prevents possible siphoning of
sewer water into the softener, if the sewer should
“back-up.”

OVERFLOW FITTINGS AND HOSE
• Insert the rubber grommet into the 3/4″ diameter
hole in the brine tank sidewall as shown.
• Push the end of the hose adapter elbow into the
grommet as shown.
• Attach a length of hose (use remaining hose from
Step 5) to the hose adapter elbow. Use a hose
clamp to hold it in place.
• Locate the other end of the hose at the drain
point. DO NOT ELEVATE this hose higher than the
elbow on the brine tank.
IMPORTANT: DO NOT TEE OVERFLOW HOSE
TO VALVE DRAIN HOSE.
NOTE: This drain is for safety only. If the cabinet
(brine tank) should
over-fill with water,
the excess is carried
to the drain.

Installation Instructions
CONNECT AND RUN THE VALVE
DRAIN HOSE
(CONT.)
• Elevating the drain hose may cause back
pressure that could reduce the brine draw during
recharge. If raising the drain line overhead is
required to get to the drain point, measure the
inlet water pressure to the softener first. For inlet
pressures between 20 and 50 psi, do not raise
higher than 8′ above the floor. For inlet pressure
above 50 psi, the drain line may be raised to a
maximum height of 14′.
CONNECTING A RIGID VALVE DRAIN TUBE
To adapt a copper drain tube to the softener, buy a

LEAKS
(CONT.)
• Place bypass valve in the “service” position
EXACTLY as follows. KEEP SOFT WATER FAUCETS
OPEN.
SLOWLY pull or slide the valve stem (out) toward
the service position, pausing several times to
allow the softener to pressurize slowly.
• After about 3 minutes, open a HOT water faucet
for 1 minute, or until all air is expelled, then
close. NOTE: If water appears cloudy or has salty
taste, allow to run for several more minutes, or
until clear.
• Close all water faucets.
• Check your plumbing work for leaks and fix
right away if any are found. Be sure to observe
previous caution notes.
• Turn on the gas or electric supply to the water
heater. Light the pilot, if applicable.
10
ADD WATER AND SALT TO THE
BRINE TANK
• Lift the salt hole cover. Add about 3 gallons of
water into the tank. Do not add into the brinewell.
• Fill tank with NUGGET, PELLET or coarse SOLAR
water softener salt with a purity of 99.5% or
higher. Do not use rock, block, granulated and ice
cream-making salts, or salt with iron-removing
additives (except for Diamond Crystal
®
Red•Out
®
brand salt). Maximum salt storage capacity is
approximately 200 lbs. Keep the salt hole cover
closed unless servicing the unit or refilling
with salt.
NOTE: If the softener is installed in a humid
basement or other damp area, it is better to fill the
tank with less salt, more frequently. Eighty to 100
lbs. of salt will last for several months, depending on
water hardness, family size and water softening
system model.

SANITIZING PROCEDURES
To complete the installation, do the following
sanitizing procedures.
Care is taken at the factory to keep your water
softener clean and sanitary. Materials used to make
the softener will not infect or contaminate your water
supply and will not cause bacteria to form or grow.
However, during shipping, storage, installation and
operation, bacteria could get into the softener. For
this reason, sanitizing as follows is suggested when
installing.
NOTE: Sanitizing is recommended by the
Water Quality Association for disinfecting.
1. Be sure to complete all installation steps, including
programming the control.
2. Pour about 3/4 oz. (1
1
⁄
2 tablespoons) of common
5.25% unscented household bleach (Clorox, Linco,
Bo Peep, White Sail, Eagle, etc.) into the brinewell.
Refer to illustration on page 5.
3. IMPORTANT: Press and hold for 3 seconds
the faceplate TOUCH/HOLD button to start an
immediate recharge. RECHARGE NOW begins to
flash in the display. The bleach will be drawn
through the water softener, and out the drain.
This process takes approximately 2 hours.
4. If, after sanitization, water from the house
faucet tastes salty or has a slight color, this is a
preservative from the resin tank. Turn on the cold
soft water faucets and drain for a few minutes or
until clear.
NOTE: When the sanitizing recharge is over, all
remaining bleach is flushed from the conditioner
and your house COLD water supply is fully soft
immediately. However, your water heater is filled
with hard water and as hot water is used, it will refill
with soft water. When all the hard water is replaced
in the water heater, hot only and mixed hot and cold
water will be fully soft. If you want totally soft water
immediately, after the above recharge, drain the
water heater until the water runs cold.
WARNING: If you do drain the water
heater, use extreme care as the hot water could
cause burns. Turn the water heater off prior to
draining.

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.
For emergency needs, hard water is available
to the home during the recharge cycles.
However, you should avoid using HOT water
because the water heater will fill with the hard
water.
Automatic Hard Water Bypass During Recharge
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.
Breaking a Salt Bridge
Sometimes, a hard crust or salt bridge forms in
the salt storage area. It is usually caused by high
humidity or the wrong kind of salt. When the salt
bridges, an empty space forms between the
water and salt. Then salt will not dissolve in the
water to make brine.
If the brine tank is full of salt, it is hard to tell
if you have a salt bridge. Salt is loose on top, but
the bridge is under it. The following is the best
way to check for a salt bridge.
Salt should be loose all the way to the bottom of
the tank. Take a broom handle or like tool, and
carefully push it down into the salt, working it up
and down. If the tool strikes a hard object (be
sure it’s not the bottom or sides of the tank), it’s
most likely a salt bridge. Carefully break the
bridge with the tool. Do not pound on the walls
of the tank.
If the wrong kind of salt made the bridge, take it
out. Then fill the tank with nugget or pellet salt
only. In humid areas, it is best to fill with less salt,
more often to prevent a salt bridge from forming.
A clean nozzle and venturi is needed for the
water softening system to work properly. This
small unit makes the suction to move brine from
the salt storage area to the resin tank during
recharge. If it becomes plugged with sand, dirt,
etc., the water softening system will not work
and you will get hard water.
To get to the nozzle and venturi, remove the
water softening system top cover. Be sure the
water softening system is in service cycle (no
water pressure at nozzle and venturi). Then, while
holding the nozzle and venturi housing with one
hand, remove the cap. Lift out the screen support
and screen, then the nozzle and venturi. Wash
and rinse the parts in warm water until clean. If
needed, use a small brush to remove iron or dirt.
Also check and clean the gasket.
NOTE: Some models have a small flow plug
located in the nozzle and venturi, and/or a small
cone shaped screen in the housing. Be sure to
check and clean these parts, if your model is
so equipped.
Carefully replace all parts in the correct
order. Lightly lubricate the o-ring seal with clean
silicone grease or petroleum jelly and place in
position. Install and tighten the cap, by hand
only. Do not overtighten the cap.

If electrical power to the water softening system is interrupted, the control display is blank, but the
control keeps correct time for about 72 hours. When power is restored, you have to reset the present
time only if the display is 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, regenerations may occur at the wrong time of day
until you reset the control to the correct time of day.
Normal Operation, Timer Display
During normal operation, the present time of day and AM or PM show in the control display
area. When the demand computer determines a regeneration is needed, RECHARGE TONIGHT
begins to flash in the display, along with the present time. RECHARGE TONIGHT flashes until
the next regeneration start time, then changes to RECHARGE NOW, which flashes until the
regeneration is over. The display also shows the current cycle in the regeneration process.
When the valve is in transition between cycles, both indicators flash.
Feature: Optional Recharge Controls
Sometimes, a manually started regeneration (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 regeneration.
■ You did not refill the storage tank with salt before it was all gone.
Use one of the following features to start a regeneration immediately, or at the next preset
regeneration start time.
RECHARGE NOW
Press and hold the TOUCH or HOLD button until RECHARGE NOW starts to flash in the control
display area. The water softening system begins an immediate regeneration and, when over in
about two hours, you will have a new supply of soft water. Once started, you cannot cancel this
regeneration.
RECHARGE TONIGHT
Touch (do not hold) the TOUCH or HOLD button. RECHARGE TONIGHT flashes in the control display
area. A regeneration will occur at the next preset regeneration start time. If you decide to cancel
this regeneration, touch the same button once more.

About the water softener system.
The timer 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 timer display.
The chart on Error Codes shows the error codes that could appear and possible defects for each code.
While an error code is displayed, the TOUCH or HOLD and DATA buttons remain operable so you can
perform the Manually Initiated Electronic Diagnostics.
Feature/Service: Automatic Electronic Diagnostics
By continuing to press the DATA button, you can scan through four displays of operational
information. This data appears in the bottom portion of the display area.
REMAINING CAPACITY — This is the percentage of water softening capacity remaining.
Immediately after a regeneration, 100% shows. As water is used, the percentage decreases until the
next regeneration. During regenerations, the percentage increases.
NOTE: Zero (%) shows until after the first regeneration begins, after connecting to
electrical power.
FLOW RATE, GPM— When using soft water, this display shows the flow rate passing through
the softener (in gallons per minute). Zero shows if water is not passing through the softener.
GALLONS TODAY— Each day, beginning at midnight, the timer keeps a running count of the
total gallons of water that have passed through the softener.
AVG. DAILY GALLONS— The figure displayed is the average gallons of water used by the
household each day over the past seven day period.
NOTE: If preferred, you can set the timer to show the reading in liters instead of gallons. If GALLONS
TODAY or AVG. DAILY GALLONS exceeds 1999, a (x10) indicator appears; this means you must
multiply the number shown by ten.

Timer/Softener, Service Checkout Procedure
If you are not getting soft water, and an error code is not displayed, use the procedures below to
find the problem. First make the following visual checks:
VISUAL CHECKS: Is there electrical power to the outlet the water softening system transformer
is plugged into?
Is there sufficient salt in the storage tank?
Is the plumbing bypass valve directing water for soft water service?
Is the valve drain hose open to the drain, not more than 8′ above the
softener, and unobstructed? If hose is above 8′, see page 8, section 5.
If you do not find a problem with the visual checks, continue below.

Service: Manually Advance Regeneration Check
This check verifies proper operation of the valve motor, brine tank fill, brine draw, regeneration
flow rates and other controller functions. First, make the initial checks and the manually initiated
electronic diagnostics.
NOTE: The face plate display must show a steady time (not flashing).
Press the TOUCH or HOLD button and hold for three seconds. RECHARGE NOW begins
to flash as the water softening system enters the fill cycle of regeneration. Remove the
brinewell cover and, using a flashlight, observe fill water entering the brine tank.
If water does not enter the tank, look for an obstructed nozzle, venturi, fill flow plug, brine
tubing or brine valve riser pipe.
After observing fill, press the TOUCH or HOLD button to move the water softening system into
brining. A slow flow of water to the drain will begin. Verify brine draw from the brine tank by
shining a flashlight into the brinewell and observing a noticeable drop in the liquid level.
NOTE: Be sure a salt bridge is not preventing salt contact with water.
If the water softening system does not draw brine, check:
■ nozzle and/or venturi dirty or defective.
■ nozzle and venturi not seated properly on gasket.
■ restricted drain (check drain fitting and hose).
■ defective nozzle and venturi seal.
■ other inner valve defect (rotor seal, rotor & disc, wave washer, etc.).
NOTE: If water system pressure is low, an elevated drain hose may cause back pressure, stopping
brine draw.
Again, press the TOUCH or HOLD button to move the softener into backwash. Look for a fast
flow of water from the drain hose.
A slow flow indicates a plugged top distributor, backwash flow plug or drain hose.
Press TOUCH or HOLD to move the water softening system into fast rinse. Again look for a fast
drain flow. Allow the water softening system to rinse for a few minutes to flush out any brine
that may remain in the resin tank from the brining cycle test.
To return the water softening system to service, press TOUCH or HOLD.

Service: Regeneration and Heavy Duty Backwash
NOTE: Each of the following functions has a factory-set default value. The defaults are: Regeneration start time
–2:00AM ; Maximum days between regenerations –0 (display shows dY–); Efficiency mode –ON; Heavy duty
backwash –OFF. The defaults are suitable for most installations. However, depending on water supply quality,
household peak water use hours, etc., adjustment is available to meet specific needs. To make a change, read
and do the following.
Regeneration (Start) Time: At the 2:00 AM regeneration start time, the water
softening system begins
regeneration at that time, ending at about 4:00 AM. This is a good time in most households because water is not
in use (see Automatic Hard Water Bypass During Regeneration section). If a different time would be better for
your
needs, do steps 1, 2, 3, 5, 7, 9 and 11 below to change the starting hour.
Maximum Days Between Regeneration: The default setting (dY–) allows the timer to control regeneration
frequency based on water usage readings from the water meter. It provides the most economical operation.
You can set a maximum time (in days) between regenerations. For example, no more than three days will pass
without a regeneration occurring if you set dY 3 in the display. A 1 to 7 day setting is available. To make a
change from the default setting, do steps
1, 3, 4, 5, 7, 9 and 11
below.
Efficiency Mode: When this feature is ON, the unit will operate at salt efficiencies of 4000 grains of harness per
pound of salt or higher. (May recharge more often using smaller salt dosage and less water). When this is ON,
the efficiency icon will show in the lower right hand corner of the display. To make a change for the
default setting, do steps 1, 3, 5, 6, 7, 9 and 11 below.
Heavy Duty Backwash: When set to ON, the backwash cycle of regeneration will be 10 minutes long instead
of the normal seven minute length. This is beneficial on some water supplies high in iron or sediment content.
To conserve water, on clean supplies, be sure the default setting OFF shows. To change this setting, do steps
1,
3, 5, 7, 8, 9 and 11
below.
Auto Regeneration When Capacity is Low: The softener will regenerate at the regeneration time only.
Although the control has a look-forward feature which anticipates normal demand, an unusually high usage
may result in a loss of softening capacity. Turning the feature ON will cause the softener to go into a
regeneration cycle when 97% of the softening capacity has been used. To change settings, do steps
1, 3, 5, 7, 9,
10 and 11 below.
Beginning from the present time display, press and hold in the SET button until begins to flash.
Press the UP or DOWN button to display the desired start time. The UP button moves the time ahead; the
DOWN button moves the time backward.
Press the SET button again, and flashes.
To set a maximum time (in days) between regenerations, press the UP or DOWN button.
Press the SET button again and the ON flashes and the efficiency mode icon
shows in the lower right hand corner of the screen.
Use the UP or DOWN arrows to toggle the efficiency mode either ON or OFF.
Press the SET button to display .
Use the UP button to change the display to ON to increase the backwash time, if desired.
Press the SET button and alternately flashes.
Use the UP button to turn Auto Regeneration cycle to ON.
Press the SET button a final time to return to present time of day.

Setting: Model Code, 12 or 24 Hour Clock and Gallons or Liters Measured
Model Code: The timer must have the right model code set to operate the water softening system
correctly. The correct code setting for the GNSM48F is A-39.
If is flashing in the display, do steps 3, 4, 6 and 8 below.
To check for the correct code setting for your model, and to reset it if needed, do steps 1, 2, 3, 4, 6
and 8 below.
NOTE: The hour clock and water measure have factory-set default values. The defaults are:
12 or 24 hour clock –12; Gallons or liters measure — gallons.
12 or 24 Hour Clock: With 12 hr set, all time displays are in standard clock time …12:00 AM to 11:59
PM. If 24 hr is set, time displays are in military time …0100 (1:00 AM) to 0000 (midnight). To change
from the 12 hr setting, do steps 1, 2, 4, 5, 6 and 8.
Gallons or Liters Measure: All water flow rate and usage displays are in gallons with the default
setting. If reset to , the same displays are shown in liters. Use steps 1, 2, 4, 6, 7
and 8 to change.
Beginning from the present time display, press and hold in the SET button until

Care and cleaning of the water softening system.
Brine (salt dissolved in water) is needed for each
and every recharge. The water for making brine
is metered into the salt storage area by the
water softening system valve and control.
However, you must keep the tank supplied
with salt.
When to refill with salt: Check the salt level a
few weeks after you install the water softening
system and every week after that. Refill when
the brine tank is from 1/3 to 1/2 full. Never allow
the water softening system to use all the salt
before you refill it. Without salt, you will soon
have hard water.
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. They
contain dirt and sediments, or mush and cake,
and will create maintenance problems.
CAUTION:
Water softening salt
with iron removing additives: Some salts
may have an additive to help the water
softening system handle iron in the water
supply. Although this additive may help to
keep the water softening system resin clean,
it may also release corrosive fumes that
weaken and shorten the life of some water
softening system parts. GE recommends
using only Diamond Crystal
®
Red•Out
®
brand salt.
Checking the Salt Storage Level and Refilling
Your water softening system takes hardness
minerals (calcium and magnesium) out of
the water. Also, it can control some (see the
Specification Guidelines section) “clear water”
iron. With clear water iron, water from a faucet
is clear when first put into a glass. After 15 to 30
minutes, the water begins to cloud or turn rust
colored. A water softening system will not
remove any iron that makes the water cloudy
or rusty as it comes from the faucet (called red
water iron). To take red water iron out of water,
or over the maximum of clear water iron,
an iron filter or other equipment is needed.
GE recommends using only Diamond Crystal
®
Red•Out
®
brand salts with Iron Fighter
®
additive
to help keep the resin bed clean of clear iron. If
your water supply has clear water iron, periodic
resin bed cleaning is needed. GE recommends
using Super Iron Out
®
brand resin bed cleaner
to thoroughly clean your resin bed if your iron
content is high. Clean the bed at least every six
months, or more often if iron appears in the soft
water between cleanings.
IMPORTANT: It is important to mix the resin bed
cleaner with water (following the manufacturer’s
instructions), pour it into the brinewell tube
(see page 5) and recharge the softener
immediately. Do not pour the resin bed cleaner
in with the salt, as it will not be as effective in
cleaning the resin, and can cause damage to
the softener if it is left in the brine tank for an
extended period due to the corrosive gases
that are formed.
