WARNING!

For your safety, the information in this manual must be followed to minimize the risk of electric shock, property damage or personal injury.

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.

■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 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.

■

Softener resins may degrade in the presence of chlorine above 1 ppm. If you have chlorine in excess of this amount, you may experience reduced resin life. In these conditions, you may wish to consider purchasing a GE point-of-entry household filtration system with a chlorine reducing filter. Contact the GE Answer Center at 1-800-626-2000 for more information.

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.

IMPORTANT SAFETY INFORMATION. READ ALL INSTRUCTIONS BEFORE USING.

Read entire manual. Failure to follow all guidelines and rules could cause personal injury or property damage.

• Before you begin installation, read these Installation Instructions completely. Then, obtain all the materials

and tools you will need to make the installation. Failure to properly install the softener voids the warranty.

• Check local codes. The installation must conform to them.

•

In the Commonwealth of Massachusetts, Plumbing Code 248 CMR shall be adhered to. Consult with your licensed plumber.

• Use only lead-free solder and flux for all sweat-solder connections, as required by state and federal codes.

• Connect the softener to the main water supply pipe

before

ahead of the

water heater.

DO NOT RUN HOT

WATER THROUGH THE SOFTENER.

Temperature of water passing through the softener must be less than 120° F.

• Use care when handling the softener. Do not turn upside down, drop, drag, or set on sharp protrusions.

• 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.)

• The softener works on 24 volt-60 Hz electrical power only. Be sure to use the included transformer.

Be sure the electric outlet and transformer are in an inside location to protect from wet weather.

• See

Where to Install the Softener

section for more details.

WARNING:

Do not use with water that is microbiologically unsafe or of unknown quality without adequate disinfection before or after the system. The water should be tested periodically to verify that the system is performing satisfactorily.

Small parts remaining after the installation could be a choke hazard. Discard safely.

Installation instructions.

CAUTION:

Certain plumbing skills are needed for installation. If you are unsure about any part of the

installation of this product, consult a professional plumber.

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 on a skin-packed cardboard piece. To avoid loss of the small parts, keep them on the skin-pack until you are ready to use them.

Important Installation Recommendations

• 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.

• Do not locate the brine tank more than 10 feet away from the resin tank.

• 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.

•

Keep the softener out of direct sunlight.

The sun’s heat may distort non-metallic parts and may damage

the electronics.

Where to Install the Softener

• In and out fittings included with the softener are 1″(nominal) copper sweat tubes. To maintain full valve

flow, 1″pipes to and from the softener fittings are recommended. You should maintain the same, or larger,

pipe size as the water supply pipe, up to the softener inlet and outlet.

• 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 nuts and washers.

• Use copper, brass or galvanized pipe and fittings. Some codes may also allow CPVC plastic pipes.

• If additional drain hose is needed for salt tank drains, it can be ordered from GE Parts at 800.626.2002.

• Garden hose with female fitting is needed for valve drain (sufficiently long to reach suitable drain).

• 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 drain.

• Clean nugget or pellet water softener salt is needed to fill the brine tank, see

Step 8

in the

Step-by-Step

Installation Instructions.

Tools and Materials Required for Installation

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,

Fig.1. 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 INand

• Support inlet and outlet plumbing in some manner (use pipe hangers)

to keep the weight off of the valve fittings.

Connect and run the valve drain hose:

• Take a length of garden hose with female fitting and attach

to the valve drain fitting, as shown in Fig. 4.

IMPORTANT:

Make sure the garden hose fitting fits

securely onto the threaded drain port.

• Locate the other end of the hose at a suitable drain point (floor drain, sump, laundry tub, etc.) that terminates at the sewer drain.

Check and comply with local codes.

IMPORTANT:

Use a high quality, thick-walled hose that will not easily kink or collapse. The water softener will not work if water cannot exit this hose during regenerations.

• 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 regeneration.

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.

• If raising the drain hose overhead is required to get to the

drain point,

do not raise higher than 8´ above the floor.

Elevating the hose may cause a back-pressure that could reduce brine draw during regenerations.

Step-by-step installation instructions.

• Turn off the gas or electric supply to the water heater, in

the possibility that the water heater may be drained while draining pipes.

• Turn off the water supply to pipes to be cut and drain the

house water pipes.

• Open both hot and cold faucets.

Install bypass valve:

• Remove plastic shipping plug and retainer from valve outlet.

NOTE:

Be sure the turbine and support are firmly in place, in the valve outlet. Blow into the valve port and observe the turbine for free rotation.

• Push the bypass valve (lubricate o-ring seals with silicone

grease) into both ports of the valve as shown in Fig. 3.

IMPORTANT:

• Snap the 2 large plastic clips in place, as shown in Fig. 3.

Be sure they snap into place. Pull on the bypass valve to make sure it is held securely in place.

Move the softener assembly into installation position:

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 as shown in Fig. 5.

Plumb IN and OUT pipes to and from softener:

CAUTION:

Observe all of the following cautions as you

connect inlet and outlet plumbing.

• 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 cross-over as shown in Fig. 1.

•

Do all sweat soldering before

connecting pipes to the bypass

valve.

Torch heat will damage plastic parts.

•

When turning threaded pipe fittings onto plastic fittings,

use care not to cross-thread.

• Use pipe joint compound on all external pipe threads.

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 and family size.

Connect to electrical power:

• Using the instruction sheet provided with the electronic

control, connect the wires from the valve to the electronic control.

• If transformer wiring is not visible at the back of the

control head, remove control cover.

DO NOT PULL ON OR

DISCONNECT WIRING.

Locate the long wire with U shaped connectors on one end. Route this wire through the rear of the control housing. Replace the control cover.

• Fasten the 2 power cable lugs (“U” shaped connectors)

to the 2 screws on the transformer, and tighten the screws. Then, plug the transformer into the electrical outlet.

• The softener works on 24 volt-60 Hz electric power. The

included transformer changes standard 120 volt AC house power to 24 volts.

Plug the transformer into a 120 volt outlet

only.

Be sure the outlet is always live so it can not be switched

off by mistake.

Program the control:

• See

Programming the Control

section.

Step-by-step installation instructions.

Install the brine tank overflow fittings and hose:

• Insert the rubber grommet into the 3/4″diameter hole

in the brine tank sidewall as shown in Fig. 5.

• Push the end of the hose adapter elbow into the grommet

as shown in Fig. 5.

• Attach a length of hose 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.

Install grounding clamps and wire:

DANGER:

Failure to properly attach ground wire could

result in electrical shock.

• If plumbing is metal, to

maintain electrical ground continuity

in the house cold water piping, install the included ground clamps as shown in Fig. 6. Be sure the pipes are clean under the clamps to assure good contact.

Flush pipes, expel air from softener, and test your installation for water leaks:

CAUTION: To avoid water or air pressure damage to softener

inner parts, be sure to do the following steps in exact order.

Fully open 2 cold soft water faucets nearby the softener.

Place bypass valve in “bypass” position by pushing the stem inward.

Fully open the house main water pipe shutoff valve. Observe a steady flow from both faucets opened in

Step A

above.

Place bypass valve in the “service” position

EXACTLY

follows.

KEEP SOFT WATER FAUCETS OPEN.

SLOWLY

pull or slide the valve stem (OUT) toward “service”, 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 CAUTIONS.

Add water and salt to the brine tank:

• Lift the cabinet (brine tank) cover. Add about 3 gallons of

water into the tank.

Do not add into the brinewell.

• Fill tank 1⁄3 to 1⁄2 full with

NUGGET, PELLET

or coarse

Step-by-step installation instructions.

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, installing and operating, 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.

Be sure to complete all installation steps, including timer programming.

Pour about 3/4 oz. of common 5.25% household bleach (Clorox, Linco, Bo Peep, White Sail, Eagle, etc.) into the

brinewell

. Refer to illustration on page 8.

IMPORTANT:

Press and hold for 3 seconds the faceplate

TOUCH/HOLD

button to start an immediate

regeneration.

Recharge Now

begins to flash in the display. The bleach is drawn into and through

the water softener

If after sanitization water from 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 above sanitizing regeneration is over, 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 regeneration, 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 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

FAST RINSE

About the water softener system.

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

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 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.

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.

About the water softener system.

Cleaning the Nozzle and Venturi Assembly

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 regeneration. 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 over-tighten the cap.

IMPORTANT: Be sure small holes in the gasket are centered directly over the small holes in the nozzle and venturi housing.

*Install with numbered side up, concave side down.

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.

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

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 elevated too high, and unobstructed?

If you do not find a problem with the visual checks, continue below.

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

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–

);

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, 8 and 9 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, 2, 3, 5, 7, 8 and 9

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, 2, 3, 5, 7, 8 and 9

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 ONwill 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, 8 and 9.

Beginning from the present time display, press and hold in the

Care and cleaning of the water softening system.

Checking the Salt Storage Level and Refilling

Brine (salt dissolved in water) is needed for each and every regeneration. 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.

Your water softening system takes hardness minerals (calcium and magnesium) out of the water. Also, it can control some (see

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

brine well

(see page 6) and regenerate 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.
