Specifications & Performance Claims

This model is efficiency rated. The efficiency rating is valid only at the minimum salt dose. This system has a
demand initiated regeneration (D.I.R.) feature that complies with specific performance specifications intended to min-

mize the amount of regenerant brine and water used in their operation.

i

his water softener has a rated softener efficiency of not less than 3,350 grains of total hardness exchange per

T
pound of salt (based on sodium chloride) and shall not deliver more salt than its listed rating or be operated at a

ustained maximum service flow rate greater than its listed rating. This system has been proven to deliver soft

s
water for at least ten continuous minutes at the rated service flow rate. The rated salt efficiency is measured by lab­oratory tests described in NSF/ANSI Standard 44. These tests represent the maximum possible efficiency that the
system can achieve. Operational efficiency is the actual efficiency after the system has been installed. It is typically
less than the rated efficiency, due to individual application factors including water hardness, water usage, and other
contaminants that reduce a softener's capacity.

*Intermittent flow rate does not represent the maximum service flow rate used for determining

the softener’s rated capacity and efficiency. Continuous operation at flow rates greater than
the service flow rate may affect capacity and efficiency performance.

**Capacity to reduce clear water iron is substantiated by laboratory test data. State of Wisconsin

requires additional treatment if water supply contains clear water iron exceeding 5 ppm.

This system conforms to NSF/ANSI Standard 44 for the specific performance claims as verified

and substantiated by test data.

Variable Salt Dose: The salt dose is selected by the electronic controls at regeneration time

based on the amount needed.

Before You Start

= The water softener requires a minimum water flow of 3 gallons per minute at the inlet. Maximum allowable inlet

ater pressure is 125 psi. If daytime pressure is over 80 psi, nighttime pressure may exceed the maximum. Use

w
a pressure reducing valve if necessary (Adding a pressure reducing valve may reduce the flow). If your home is
equipped with a back flow preventer, an expansion tank must be installed in accordance with local codes and laws.

The water softener works on 24V DC electrical power, supplied by a direct plug-in power supply (included). Be

=

sure to use the included power supply and plug it into a nominal 120V, 60 Hz household outlet that is in a dry
location only, grounded and properly protected by an overcurrent device such as a circuit breaker or fuse.

= Do not use this system to treat water that is microbiologically unsafe or of unknown quality without adequate dis-

infection upstream or downstream of the system.

European Directive 2002/96/EC requires all electrical and electronic equipment to be disposed of accord-

ing to Waste Electrical and Electronic Equipment (WEEE) requirements. This directive or similar laws are
in place nationally and can vary from region to region. Please refer to your state and local laws for prop­er disposal of this equipment.

In the state of Massachusetts: The Commonwealth of Massachusetts plumbing code 248-CMR shall
be adhered to. A licensed plumber shall be used for this installation.

In the state of California: You must turn the Salt Efficiency Feature setting to ON. This may initiate
more frequent recharges. However, it will operate at 4,000 grains per pound of salt or higher. To turn
on the Salt Efficiency Feature, follow the instructions in the “Salt Efficiency” section of this manual.

Do not return the water softener to store.

IRON

Iron in water can cause stains on clothing and plumb­ing fixtures. It can negatively affect the taste of food,
drinking water, and other beverages. Iron in water is
measured in parts per million (ppm). The total* ppm of
iron, and type or types*, is determined by chemical
analysis. Four different types of iron in water are:

= Ferrous (clear water) iron
= Ferric (red water) iron
= Bacterial and organically bound iron
= Colloidal and inorganically bound iron (ferrous or

ferric)

Ferrous (clear water) iron is soluble and dissolves in
water. This water softener will reduce moderate
amounts of this type of iron (see specifications).**

Ferrous (clear water) iron is usually detected by taking
a sample of water in a clear bottle or glass.
Immediately after taking, the sample is clear. As the
water sample stands, it gradually clouds and turns
slightly yellow or brown as air oxidizes the iron. This
usually occurs in 15 to 30 minutes.

When using the softener to reduce Ferrous (clear
water) iron, add 5 grains to the hardness setting for
every 1 ppm of Ferrous (clear water) iron. See "Set
Water Hardness Number" section.

Ferric (red water), and bacterial and organically bound
irons are insoluble. This water softener will not
remove ferric or bacterial iron. This iron is visible

immediately when drawn from a faucet because it has
oxidized before reaching the home. It appears as
small cloudy yellow, orange, or reddish suspended
particles. After the water stands for a period of time,
the particles settle to the bottom of the container.
Generally these irons are removed from water by filtra­tion. Chlorination is also recommended for bacterial
iron.

Colloidal and inorganically bound iron is of ferric or fer­rous form that will not filter or exchange out of water.
This water softener will not remove colloidal iron. In
some instances, treatment may improve colloidal iron
water. Colloidal iron water usually has a yellow
appearance when drawn. After standing for several
hours, the color persists and the iron does not settle,
but remains suspended in the water.

SEDIMENT

Sediment is fine, foreign material particles suspended
in water. This water softener will not remove sedi­ment. This material is most often clay or silt. Extreme
amounts of sediment may give the water a cloudy
appearance. A sediment filter installed upstream of
the water softener normally corrects this situation.

* Water may contain one or more of the four types of

iron and any combination of these. Total iron is the
sum of the contents.

** Capacity to reduce clear water iron is substantiated

by laboratory test data.

Installation Requirements

LOCATION REQUIREMENTS

Consider all of the following when selecting an installa­tion location for the water softener.

Do not locate the water softener where freezing

=

temperatures occur. Do not attempt to treat water
over 120ºF. Freezing temperatures or hot water
damage voids the warranty.

= To condition all water in the home, install the water

softener close to the water supply inlet, and
upstream of all other plumbing connections, except
outside water pipes. Outside faucets should remain
on hard water to avoid wasting conditioned water
and salt.

= A nearby drain is needed to carry away regenera-

tion discharge (drain) water. Use a floor drain,
laundry tub, sump, standpipe, or other options
(check your local codes). See "Air Gap
Requirements" and "Valve Drain Requirements"
sections.

= The water softener works on 24V DC electrical

power, supplied by a direct plug-in power supply
(included). Provide nearby a 120V, 60 Hz electrical
outlet in accordance with NEC and local codes.

= Always install the water softener between the water

inlet and water heater. Any other installed water
conditioning equipment should be installed between
the water inlet and water softener (See Figure 4
below).

= Avoid installing in direct sunlight. Excessive sun

heat may cause distortion or other damage to non­metallic parts.

= Install on a flat, stable surface that evenly supports

the weight of the water softener.

PLUMBING CODES

All plumbing must be completed in accordance with
national, state and local plumbing codes.

In the state of Massachusetts: The Commonwealth
of Massachusetts plumbing code 248-CMR shall
be adhered to. A licensed plumber shall be used
for this installation.

AIR GAP REQUIREMENTS

A drain is needed for the water discharged from the
valve during the softener’s regeneration cycle (See
Figure 3). A floor drain, close to the water softener, is
preferred. A laundry tub, standpipe, etc. are other
drain options. Secure valve drain hose in place.
Leave an air gap of 1-1/2” between the end of the
hose and the drain. This gap is needed to prevent
backflow of sewer water into the water softener. Do
not put the end of the drain hose into the drain.

VALVE DRAIN REQUIREMENTS

Using the flexible drain hose (included), measure and
cut to the length needed. Flexible drain hose is not
allowed in all localities (check your plumbing codes). If
local codes do not allow use of a flexible drain hose, a
rigid valve drain run must be used. Purchase a com­pression fitting (1/4 NPT x 1/2 in. minimum tube) and
1/2" tubing from your local hardware store. Plumb a
rigid drain as needed (See Figure 6).

NOTE: Avoid drain hose runs longer than 30 feet.

Avoid elevating the hose more than 8 feet
above the floor. Make the valve drain line as
short and direct as possible.

INLET / OUTLET PLUMBING OPTIONS

Always install either a single bypass valve (provided),
as shown in Figure 7, or, if desired, parts for a 3 valve
bypass system (not included) can be purchased and
assembled, as shown in Figure 8. Bypass valves
allow you to turn off water to the softener for mainte­nance if needed, but still have water in house pipes.

Use:

= Copper pipe
= Threaded pipe
= PEX (Crosslinked Polyethylene) pipe
= CPVC plastic pipe
= Other pipe approved for use with potable water

IMPORTANT: Do not solder with plumbing attached to

the single bypass valve. Soldering heat
will damage the plastic valve.

2. Shut off the electric or fuel supply to the water heater.

3. Open all faucets to drain all water from house pipes.

NOTE: Be sure not to drain water from the water

heater, as damage to the water heater ele­ments could result.

ASSEMBLY

1. Rheem®models are factory assembled. During

installation, unsnap and remove the top cover,
together with the salt lid, to expose the softener
valve assembly. Set them aside to prevent damage.
Check the brinewell to be sure it is secured and ver­tical (See Figure 11).

2. Install the brine tank overflow grommet and elbow

into the 13/16” diameter hole in the back of the salt
storage tank wall.

NOTE: See “Air Gap Requirements” section.

FIG. 9

MOVE THE UNIT INTO PLACE

1. Move the water softener into the desired location.

Set it on a solid, level surface.

IMPORTANT: Do not place shims directly under the salt

storage tank to level the softener. The
weight of the tank, when full of water and
salt, may cause the tank to fracture at the
shim.

2. Visually check and remove any debris from the water
softener valve inlet and outlet ports. Carefully remove
the two large plastic clips (you will use them).

3. Make sure the turbine assembly spins freely in the
"out" port of the valve (See Figure 10).

4. If not already done, put a light coating of silicone
grease on the single bypass valve o-rings.

5. Push the single bypass valve into the softener valve
as far as it will go. Snap the two large holding clips
into place, from the top down as shown in Figures 12
& 13.

IMPORTANT: Be sure the clips snap firmly into place so

the single bypass valve will not pull out.

Installation Instructions

COMPLETE INLET AND OUTLET PLUMBING

Measure, cut, and loosely assemble pipe and fittings
from the main water pipe to the inlet and outlet ports of

he water softener valve. Be sure to keep fittings fully

t
together, and pipes squared and straight.

Be sure hard water supply pipe goes to the water sof­tener valve inlet side.

NOTE: Inlet and outlet are marked on the water sof-

tener valve. Trace the water flow direction to
be sure hard water is to inlet.

IMPORTANT: Be sure to fit, align and support all

plumbing to prevent putting stress on
the water softener valve inlet and outlet.
Undue stress from misaligned or unsup­ported plumbing may cause damage to
the valve.

Complete the inlet and outlet plumbing for the type of
pipes you will be using.

Installation Instructions

COLD WATER PIPE GROUNDING

CAUTION: The house cold water pipe (metal only)

is often used as a ground for the house
electrical system, The 3-valve bypass
type of installation, shown in Figure 8,
will maintain ground continuity. If you
use a plastic bypass valve at the unit,
continuity is broken. To restore the
ground, do the following:

1. Install a #4 copper wire across the removed section

of main water pipe, securely clamping it at both
ends (See Figure 14) - parts not included.

NOTE: Check local plumbing and electrical codes

for proper installation of the ground wire.
The installation must conform to them. In
Massachusetts, plumbing codes of
Massachusetts shall be conformed to.
Consult with your licensed plumber.

INSTALL VALVE DRAIN HOSE

NOTE: See valve drain options on pages 6 & 7.

1. Measure, cut to needed length and connect the 3/8”

drain line (provided) to the water softener valve
drain fitting. Use a hose clamp to hold the hose in
place.

IMPORTANT: If codes require a rigid drain line see

“Valve Drain requirements" section.

2. Run the drain hose (or a rigid line) to the floor drain.
Secure drain hose. This will prevent “whipping'' dur­ing regenerations. Be sure to provide a 1-1/2”

minimum air gap to prevent possible sewer
water backup. See “Air Gap Requirements" sec-

tion.

NOTE: In addition to a floor drain, you can use a laun-

dry tub or standpipe as a drain point for this
hose. Avoid long drain hose runs, or elevating
the hose more than 8 feet above the floor.

INSTALL SALT STORAGE TANK OVERFLOW
HOSE

. Measure, cut to needed length and connect the 3/8”

1

drain line (provided) to the salt storage tank overflow

lbow and secure in place with a hose clamp.

e

2. Route the hose to the floor drain, or other suitable
drain point no higher than the drain fitting on the salt
storage tank (This is a gravity drain). If the tank
overfills with water, the excess water flows to the
drain point. Cut the drain line to the desired length
and route it neatly out of the way.

IMPORTANT: For proper operation of the water soften-

er, do not connect the water softener
valve drain tubing to the salt storage
tank overflow hose.

TEST FOR LEAKS

To prevent air pressure in the water softener and
plumbing system, complete the following steps in order:

1. Fully open two or more softened cold water faucets
close to the water softener, located downstream
from the water softener.

2. Place the bypass valve (single or 3 valve) into the
"bypass" position. See Figures 7 & 8 on Page 7.

3. Slowly open the main water supply valve. Run
water until there is a steady flow from the opened
faucets, with no air bubbles.

4. Place bypass valve(s) in "service" or soft water posi­tion as follows:

= Single bypass valve: Slowly move the valve stem

toward "service," pausing several times to allow
the water softener to fill with water.

= 3 valve bypass: Fully close the bypass valve and

open the outlet valve. Slowly open the inlet valve,
pausing several times to allow the water softener
to fill with water.

5. After about three minutes, open a hot water faucet
until there is a steady flow and there are no air bub­bles, then close this faucet.

6. Close all cold water faucets and check for leaks at
the plumbing connections that you made.

7. Check for leaks around clips at softener’s inlet and
outlet. If a leak occurs at a clip, depressurize the
plumbing (turn off the water supply and open
faucets) before removing clip. When removing clips
at the softener’s inlet or outlet, push the single
bypass valve body toward the softener (See Figure

15). Improper removal may damage clips. Do not
reinstall damaged clips.

ADD WATER AND SALT TO THE SALT
STOR AGE TANK

1. Using a container, add about three gallons of clean

water into the salt storage tank.

2. Add salt to the storage tank. Use nugget, pellet or
coarse solar salts with less than 1% impurities.

PLUG IN THE POWER SUPPLY

During installation, the water softener wiring may be
moved or jostled from place. Be sure all leadwire con­nectors are secure on the back of the electronic board
and be sure all wiring is away from the valve gear and
motor area, which rotates during regenerations.

1. Plug the water softener’s power supply into an elec­trical outlet that is not controlled by a switch and is
approved by local codes.

NOTE: The water heater is filled with hard water and,

as hot water is used, it will refill with condi­tioned water. In a few days, the hot water will
be fully conditioned. To have fully conditioned
hot water immediately, wait until the initial
recharge is over. Then, drain the water heater
(following instructions for water heater) until
water runs cold.

SANITIZE THE WATER SOFTENER /
SANITIZE AFTER SERVICE

Care is taken at the factory to keep your unit clean and
sanitary. Materials used to make the unit 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 unit. For this reason, sanitizing as follows is
suggested* when installing.

1. Slide open the salt lid, remove the brinewell cover
and pour about 3 oz. (6 tablespoons) of household
bleach into the softener brinewell. Replace the
brinewell cover.

2 Make sure the bypass valve(s) is in the “service”

(open) position.

3 Start a recharge: Press the RECHARGE button and

hold for 3 seconds, until “Recharge Now” begins to
flash in the display. This recharge draws the sanitiz­ing bleach into and through the water softener. Any
air remaining in the unit is purged to the drain.

4. After the recharge has completed, fully open a cold
water faucet, downstream from the softener, and
allow 50 gallons of water to pass through the sys­tem. This should take at least 20 minutes. Close
the faucet.

*Recommended by the Water Quality Association. On some

water supplies, the unit may need periodic disinfecting.

RESTART THE WATER HEATER

1. Turn on the electricity or fuel supply to the water

heater and relight the pilot, if applicable.

NOTE: The water heater is filled with hard water and,

as hot water is used, it refills with conditioned
water. In a few days, the hot water will be fully
conditioned. To have fully conditioned hot
water immediately, wait until the initial recharge
(previous step) is over. Then, drain the water
heater (following instructions for water heater)
until water runs cold.

PROGRAM THE CONTROLLER

1. Install the softener’s top cover and salt lid.

2. Complete the Programming Steps on Pages 12-14.

NOTE: If your water supply contains iron, compen-

sate for it by adding to the water hardness
number. For example, assume your water is
20 gpg hard and contains 2 ppm iron. Add 5
to the hardness number for each 1 ppm of
iron. In this example, you would use 30 for
your hardness number.

20 gpg hardness

2 ppm iron x 5 = 10 +10

FIG. 23

1. Press the r UP or s DOWN buttons to set the

type of salt you will be using in your water softener.
The default is NaCl (standard Sodium Chloride
water softener salt). If you will be using KCl
(Potassium Chloride) instead, be sure to set salt
type to KCl. This setting adjusts the regeneration
cycle times to compensate for the different rate at
which KCl dissolves. See also Page 17 for more
information on salt types.

2. When the correct salt type is displayed, press the
SELECT button. The display will change to show
the “SET SALT LEVEL” screen.

STEP 5. SET SALT LEVEL

If you completed the previous step, the words “RE ­CHARGE TIME" should show in the display. Otherwise,
press the SELECT button several times until they do.

FIG. 22

1. The softener’s default recharge start time is 2:00

AM. This is normally a time of day when water is
not being used in the household. Hard water
bypasses the softener if the household draws
water during the recharge cycle. If a different
recharge start time is desired, press the

r UP or

s DOWN buttons to change the time, in 1-hour

increments. Be sure AM or PM is correct.

2. When the desired recharge start time is displayed,
press the SELECT button, and the display will
change to show one of the salt type screens in

PROGRAM MEMORY

If electrical power to the softener goes off, the time
display is blank but the electronic controller keeps the
correct time for several hours. When electrical power
comes on again, you will have to reset the present
time only if the display is flashing. The HARDNESS
and RECHARGE TIME never require resetting unless
a change is desired. Even if the clock is incorrect
after a long power outage, the softener works as it
should to keep your water soft, however, regenera­tions may occur at the wrong time of day until you
reset the clock to the correct time of day.

Sometimes, a manually initiated recharge (regenera­tion) may be desired, or needed. Two examples are:

= You have used more water than usual (guests visit-

ing) and you may run out of soft water before the
next automatic regeneration.

= You did not add salt to the softener before it ran

out. Add salt to the softener before regenerating.

You can start a regeneration immediately, or you can
set the controller to regenerate at the next preset
recharge time (2:00 AM, or as set).

RECHARGE NOW

Press the RECHARGE button and hold for 3 sec­onds, until the words “RECHARGE NOW” begin to
flash in the display. The softener enters the fill cycle
of regeneration immediately. This regeneration will
take about 2 hours to complete. Then, you will have
soft water again.

FIG. 26

RECHARGE TONIGHT

Press and release (do not hold) the RECHARGE but­ton. “RECHARGE TONIGHT” will begin flashing in
the display, and the softener will begin regeneration
at the next preset recharge time (2:00 AM, or as set).
If you decide to cancel the regeneration before it
starts, press and release the RECHARGE button
once more. “RECHARGE TONIGHT” will stop flash­ing in the display.

Routine Maintenance

ADDING SALT

Lift the salt lid and check the salt storage level fre-

uently. If the water softener uses all the salts before

q
you refill it, you will experience hard water. Until you
have established a refilling routine, check the salt
every two or three weeks. Always add if less than 1/4
full. Be sure the brinewell cover is on.

NOTE: In humid areas, it is best to keep the salt stor-

age level lower, and to refill more often to
avoid salt “bridging”.

Recommended Salt: Nugget, pellet or coarse solar
salts with less than 1% impurities.

Salt Not Recommended: Rock salt, high in impuri­ties, block, granulated, table, ice melting, ice cream
making salts, etc.

BREAKING A SALT BRIDGE

Sometimes, a hard crust or salt “bridge” forms in the
brine tank. 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 the salt.
Then, salt will not dissolve in the water to make brine.
Without brine, the resin bed is not recharged and
hard water will result.

If the storage tank is full of salt, it is difficult to tell if
you have a salt bridge. A bridge may be underneath
loose salt. Take a broom handle, or like tool, and
hold it next to the water softener. Measure the dis­tance from the floor to the rim of the water softener.
Then, carefully push the broom handle straight down
into the salt. If a hard object is felt before the pencil
mark is even with the top, it is most likely a salt
bridge. Carefully push into the bridge in several
places to break it. Do not use any sharp or pointed
objects as you may puncture the brine tank. Do not
try to break the salt bridge by pounding on the out­side of the salt tank. You may damage the tank.

CLEANING THE NOZZLE & VENTURI

A clean nozzle & venturi (See Figure 37) is a necessity
for the water softener to work properly. This small
component creates the suction to move brine from the
brine tank, into the resin tank. If it should become

lugged with sand, silt, dirt, etc., the water softener will

p
not work, and hard water will result.

FIG. 37

To get access to the nozzle & venturi, remove the
water softener’s top cover. Put the bypass valve(s)
into the bypass position. Be sure the water softener is
in soft water (service) cycle (no water pressure at noz­zle & venturi). Then, holding the nozzle & venturi
housing with one hand, un screw the cap. Do not lose
the o-ring seal. Lift out the screen support and screen.
Then, remove the nozzle & venturi disc, gasket and
flow plug(s). Wash the parts in warm, soapy water
and rinse in fresh water. Be sure to clean both the top
and bottom of the nozzle & venturi disc. If needed,
use a small brush to remove iron or dirt. Do not
scratch, misshape, etc., surfaces of the nozzle & ven­turi.

Gently replace all parts in the correct order. Lubricate
the o-ring seal with silicone grease and locate in place.
Install and tighten the cap by hand, while supporting
the housing. Overtightening may break the cap or
housing. Put the bypass valve(s) into service (soft
water) position.

Recharge the softener to reduce water level in the
tank. This will also assure that the softener is com­pletely recharged and ready to provide softened water
again. Check the water level in the tank by looking
down the brinewell. If the water level does not drop
after a recharge, the problem has not been resolved.
Call 1-800-754-7027.

PROTECT THE WATER SOFTENER FROM
FREEZING

If the softener is installed where it could freeze (sum­mer cabin, lake home, etc.), you must drain all water
from it to stop possible freeze damage. To drain the
softener:

1. Close the shut-off valve on the house main water
pipe, near the water meter or pressure tank.

2. Open a faucet in the soft water pipes to vent pres­sure in the softener.

3. Move the stem in the single bypass valve to bypass.
Close the inlet and outlet valve in a 3 valve bypass
system, and open the bypass valve. If you want
water in the house pipes again, reopen the shut-off
valve on the main water pipe.

4. Unplug the power supply at the wall outlet. Remove
the softener’s top cover, together with the salt lid.
Take off both drain hoses if they will interfere with
moving the softener into position over the drain.

5. Carefully remove the large holding clips at the sof­tener inlet and outlet. Separate the softener from
the plastic installation adaptors, or from the bypass
valve.

6. Lay a piece of 2 inch thick board near the floor drain
(See Figure 38).

7. Move the softener close to the drain. Slowly and
gently, tip it over until the rim rests on the wood
block with the inlet and outlet over the drain. Do not
allow the softener’s weight to rest on the inlet and
outlet fittings or they may break.

8. Tip the bottom of the softener up a few inches and
hold until all water has drained. Leave the softener
laying like this until you are ready to use it. Plug the
inlet and outlet with clean rags to keep dirt, bugs,
etc. out.

Troubleshooting

AUTOMATIC ELECTRONIC DIAGNOSTICS

his water softener has a self-diagnostic function for

T
the electrical system (except input power and/or water
meter). The water softener monitors electronic
components and circuits for correct operation. If a
malfunction occurs, an error code appears in the
display.

FIG. 39

While an error code appears in the display, all buttons
are inoperable except the SELECT button. SELECT
remains operational so the service person can per­form the Manual Advance Diagnostics, see below, to
further isolate the problem.

Procedure for removing error code from
display:

1. Unplug transformer from electrical outlet.

2. Correct problem.

3. Plug in transformer.

4. Wait 8 minutes. The error code will return if
the problem was not corrected.

MANUAL ADVANCE DIAGNOSTICS

Use the following procedures to advance the water
softener through the regeneration cycles to check
operation.

Lift off the salt lid, remove the top cover by unlocking
the tabs in the back and rocking forward, to observe
cam and switch operation during valve rotation.

1. Press and hold SELECT for 3 seconds until “000”
shows in the display, then release.

2. The 3 digits indicate water meter operation as
follows:

000 (steady) = Soft water not in use, and no flow

through the meter.

Open a nearby soft water faucet.

000 to 199 (continual) = Repeats for each gallon

of water passing through
the meter.

3. The letter “P” and a dash (or dashes) indicate
POSITION switch operation (See Figure 40). If the
letter appears, the switch is closed. If the dash
shows, the switch is open.

checks, and the manual initiated diagnostics.

NOTE: The electronic control display must show a

1. Press the RECHARGE button and hold in for 3

seconds. RECHARGE begins to flash as the
softener’s valve advances from the service to fill
position. Remove the brinewell cover and, using a
flashlight, observe fill water entering the tank.

low flow of water to the drain will begin. Verify

s
brine draw from the brine tank by shining a
flashlight into the brinewell and observing a
noticeable drop in the liquid level. This may take
15 to 20 minutes.

NOTE: Be sure water is in contact with the salt, and

not separated by a salt bridge (See "Breaking
A Salt Bridge" section).

If the water softener does not draw brine, check for

(most likely to least likely):

= Dirty or plugged nozzle and venturi, see

"Cleaning the Nozzle and Venturi" section.

= Nozzle and venturi not seated on the gasket, or

gasket deformed.

= Valve seals leaking (See Troubleshooting).

= Restriction in valve drain, causing a back-pressure

(bends, kinks, elevated too high, etc.). See
"Install Valve Drain Hose" section.

= Obstruction in brine valve or brine tubing.

NOTE: If water system pressure is low, a too-long or

elevated drain hose may cause back
pressure, stopping brine draw. Avoid drain
hose runs longer than 30 feet. Avoid elevat­ing the hose more than 8 feet above the floor.

3. Press the RECHARGE button to move the
softener’s valve into the backwash position. Look
for a fast flow of water from the drain hose. Check
that the drain can adequately handle the flow and
volume.

An obstructed flow indicates a plugged top

distributor, backwash flow plug, or drain hose.

4. Press the RECHARGE button to move the soften­er’s valve into the fast rinse position. Again look
for a fast drain flow. Allow the softener to rinse for
a few minutes to flush out any brine that may
remain in the resin tank from the brining cycle test.

5. To return the softener’s valve to the service posi­tion, press the RECHARGE button.

Warrantor: Water Channel Partners, 1890 Woodlane Drive, Woodbury, MN 55125

Warrantor guarantees, to the original owner, that:

One Year Full Warranty:

● For a period of one (1) year from the date of purchase, all parts will be free from defects in materials and
workmanship and will perform their normal functions.

● For a period of one (1) year from the date of purchase, labor to repair or replace any part deemed to be defective in

corrode, leak, burst, or in any other manner, fail to perform its proper functions.

● For a period of three (3) years from the date of purchase, the electronic control board will be free of defects in
materials and workmanship and will perform its normal functions.

If, during such respective period, a part proves to be defective, Warrantor will ship a replacement part, directly to your

General Provisions

The above warranties are effective provided the water softener is operated at water pressures not exceeding 125 psi, and
at water temperatures not exceeding 120°F; provided further that the water softener is not subject to abuse, misuse,
alteration, neglect, freezing, accident or negligence; and provided further that the water softener is not damaged as the
result of any unusual force of nature such as, but not limited to, flood, hurricane, tornado or earthquake.
Warrantor is excused if failure to perform its warranty obligations is the result of strikes, government regulation, materials
shortages, or other circumstances beyond its control.

*THERE ARE NO WARRANTIES ON THE WATER SOFTENER BEYOND THOSE SPECIFICALLY DESCRIBED ABOVE.
ALL IMPLIED WARRANTIES, INCLUDING ANY IMPLIED WARRANTY OF MERCHANTABILITY OR OF FITNESS FOR
A PARTICULAR PURPOSE, ARE DISCLAIMED TO THE EXTENT THEY MIGHT EXTEND BEYOND THE ABOVE
PERIODS. THE SOLE OBLIGATION OF WARRANTOR UNDER THESE WARRANTIES IS TO REPLACE OR REPAIR
THE COMPONENT OR PART WHICH PROVES TO BE DEFECTIVE WITHIN THE SPECIFIED TIME PERIOD, AND
WARRANTOR IS NOT LIABLE FOR CONSEQUENTIAL OR INCIDENTAL DAMAGES. NO WARRANTOR DEALER,
AGENT, REPRESENTATIVE, OR OTHER PERSON IS AUTHORIZED TO EXTEND OR EXPAND THE WARRANTIES
EXPRESSLY DESCRIBED ABOVE.

Some states do not allow limitations on how long an implied warranty lasts or exclusions or limitations of incidental or
consequential damage, so the limitations and exclusions in this warranty may not apply to you. This warranty gives you
specific legal rights, and you may have other rights which vary from state to state. This warranty applies to consumer­owned installations only.
