IMPORTANT SAFETY INFORMATION.
READ ALL INSTRUCTIONS BEFORE USING.
WARNING!
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 regeneration 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.
■ The water softening system works on
24 volt-60 Hz electrical power only.
Be sure to use
only the included transformer.
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.
SA VE 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 heat
may cause distortion or other damage to nonmetallic parts.
■Properly ground to conform with all governing
codes and ordinances.
■Use only
lead-free solder and flux
for all sweatsolder 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.
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. If you did not receive Installation Instructions, you can receive one by
calling us toll-free at the GE Answer Center
®
800.626.2000.
For your safety, the information in this manual must be followed to minimize the risk of electric shock,
property damage or personal injury.

About the water softener system.
Customer ServiceTroubleshooting TipsOperating InstructionsSafety Instructions
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 regeneration, or recharge. Regeneration 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
FASTRINSE
.
Automatic Hard Water Bypass During Regeneration
For emergency needs, hard water is available to
the home during the regeneration cycles.
However, you should avoid using HOT water because
the water heater will fill with the hard water.
Fill Brine Rinse
Salt dissolved in water is called brine. Brine is
needed to clean the hard minerals from the
resin beads. To make the brine, water flows into
the salt storage area during the fill stage as shown.
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.
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 upthrough the resin
tank at a fast flow rate, flushing accumulated iron,
dirt, and sediments from the resin bed and to 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 tank, and packs the resin bed.
After fast rinse, the
water softening system
returns
to soft water service.

NOTE:
If
15
(factory default) and
HARDNESS
do not show in the display, press
SELECT
until
they do.
Press the UP or DOWN button to set your water hardness number in the display. DOWN
moves the display down to 1. UP moves the display up to the maximum setting.
NOTE:
Each press of a button changes the display by 1 between 1 and 25. Above 25, the
display changes 5 at a time…25, 30, 35, etc. Holding a button in changes the numbers twice
each second.
When the water hardness number shows, press
SELECT
to set.
You can get the grains per gallon (gpg) hardness of your water supply from a water
analysis laboratory, or call and ask your local water department, if you are on a
municipal supply. (17.1 parts per million (ppm) =1 grain per gallon.)

Control Settings Required
Upon installation and after an extended power outage. See the
Program Memory
section.
■ When the transformer is plugged into the electrical outlet, 12:00 AM is flashing and
PRESENTTIME
shows in the display area. Program the control as instructed below. If
SR- -
is flashing, use the UP button to set the correct SRcode as follows:
SR17
for model
GNSF23Z,
SR35
for model GNSF35Z and
SR18
for model GNSF18Z. If you pass by the
correct code number, use the DOWN button. Then, press the
SELECT
button and program
the control.
If the wrong SR code shows for your model,
see
Manually Initiated Electronic Diagnostics
section.
■ A “beeper” sounds while pressing buttons for control programming. One beep signals a
change in the control display. Repeated beeps mean the control will not accept a change
from the button you have pressed and you should use another button.
■ To set the control, you will use the UP, DOWN and
SELECT
buttons.
Set Present Time of Day
Upon installation and after an extended power outage. See the
Program Memory
section.
NOTE:
If the words
PRESENT TIME
do not show in the display, press the
SELECT
button until
they do.
Press the UP or DOWN button to set. The UP button moves the display ahead; the DOWN
moves the time backward. If present time is between noon and midnight, be sure PM
shows .
If present time is between midnight and noon, be sure AM shows
.
When the present time shows in display, press
SELECT
to set.
