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

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.

Normal Operation, Control Displays
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.
Feature: Program Memory
If electrical power to the water softening system is
interrupted, the control display is blank, but the
control keeps correct time for about six 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.
Feature: Optional Recharge Controls
Sometimes, a manually started regeneration
(recharge) may be desired or needed.
T wo
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.
Use one of the following features to start a
regeneration immediately, or at the next preset
regeneration start time.
RECHARGE TONIGHT
Touch (do not hold) the

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 or brine
tubing. See
Care and cleaning of the water softener system
section.
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
over an extended period of time.
NOTE:
Be sure a salt bridge is not preventing water from contacting salt. See
Care and cleaning of
the water softening system
section.
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 water softening system 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 the
TOUCH or HOLD
button 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.

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 at
least 1/3 to 1/2 full of 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 ironremoving additives:
Some salts 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.
Do not
use salt with iron-
removing additives.
Customer ServiceTroubleshooting TipsOperating InstructionsSafety Instructions
11
Cleaning Iron Out of the Water Softening System
Your water softening system takes hard 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
WILLNOT
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.
If your water supply has clear water iron, periodic resin bed cleaning is needed. Clean the
bed at least every six months, or more often if iron appears in the soft water between
treatments, using a resin bed cleaner. Follow directions on the resin bed cleaner container.
Resin bed cleaner is available from most hardware stores.
Sanitizing Procedure
Care is taken at the factory to keep your water softening system clean and sanitary. Materials
used to make the water softening system 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 upon installation and once per year thereafter.
NOTE:
Sanitizing is recommended by the Water Quality Association for disinfecting.
Be sure to complete all installation steps, including control programming.
Mix about 3/4 oz. of common 5.25% household bleach (Clorox, Linco, Bo Peep, White
Sail, Eagle, etc.) with about 1 quart of water. Pour the mixture into the brinewell. It is
important not to pour straight bleach into the softener.
IMPORTANT:
Press and hold (for 3 seconds) the
TOUCH or HOLD
button on the control
panel to start an immediate regeneration.
RECHARGE NOW
begins to flash in the display.
The bleach is drawn into and through the water softening system to sanitize it. This
sanitizing regeneration is over in about 2 hours. Then soft water is available for your use.
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.
DANGER:
If you do drain the water heater, use extreme care as the hot water could
cause burns.

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.

Clean 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 and place in position.
Install and tighten the cap, by hand only. Do not over-
tighten the cap or housing
