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.

A video describing important use and care instructions has been included with the product for your use.

NOTE:

(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
