Specificati ns & Perf rmance Claims
This model is efficiency rated. The efficiency rating is valid only at the minimum salt dose. This system has a
demand initiated regeneration ( .I.R.) feature that complies with specific performance specifications intended to min-
imize the amount of regenerant brine and water used in their operation.
This water softener and filter has a rated softener efficiency of not less than 3,350 grains of total hardness exchange
per pound of salt (based on sodium chloride) and shall not deliver more salt than its listed rating or be operated at a
sustained maximum service flow rate greater than its listed rating. This system has been proven to deliver soft
water for at least ten continuous minutes at the rated service flow rate. The rated salt efficiency is measured by lab-
oratory 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.
While testing was performed under standard laboratory conditions, actual performance of the system may vary based
on local water conditions. This system has been tested according to NSF/ANSI Standard 42 for the reduction of chlorine
taste and odor. The concentration of the indicated substance in water entering the system was reduced to a concentra-
tion less than or equal to the permissible limit for water leaving the system, as specified in NSF/ANSI Standard 42.

=The water softener requires a minimum water flow of 3 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 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 C 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.
=o 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 irective 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 prop-
er disposal of this equipment.
Bef re Y u Start
Water Treatment Inf rmati n
Iron
Iron in water can cause stains on clothing and plumb-
ing 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 filtra-
tion. Chlorination is also recommended for bacterial
iron.
Colloidal and inorganically bound iron is of ferric or fer-
rous 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 material is most often clay or silt.
Extreme amounts of sediment may give the water a
cloudy appearance, and may require a sediment filter
be installed upstream of the water softener.
* 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.

ocation Requirements
Consider all of the following when selecting an installa-
tion location for the water softener.
=o not locate the water softener where freezing
temperatures occur. o not attempt to treat water
over 100ºF. 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 rain Requirements"
sections.

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 com-
pression 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 mainte-
nance 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: o not solder with plumbing attached to
the single bypass valve. Soldering heat
will damage the plastic valve.

Installati n Instructi ns
Step 1. Turn Off Water Supply
1. Close the main water supply valve, located near the
well pump or water meter.
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 ele-
ments could result.
Step 2. Assembly
1. Morton®water softener models are factory assem-
bled. uring 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. Lift the brine valve out of the brinewell. Make sure
the float stem is parallel to the stand tube so the
seals will seat properly during operation. Place the
brine valve back into the bottom of the brinewell and
reinstall the brinewell cover.
3. Install the brine tank overflow grommet and elbow
into the 13/16” diameter hole in the back of the salt
storage tank wall.
Step 3. Move the Unit into Place
1. Move the water softener into the desired location.
Set it on a solid, level surface.
IMPORTANT: o 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.

Make sure that the tabs are fully seated.
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.
Step 4. 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
the water softener valve. Be sure to keep fittings fully
together, and pipes squared and straight.
Be sure hard water supply pipe goes to the water sof-
tener 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 unsup-
ported plumbing may cause damage to
the valve.
Complete the inlet and outlet plumbing for the type of
pipes you will be using.

Step 5. 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.

Step 7. Install Salt Storage Tank
Over flow Hose
1. Measure, cut to needed length and connect the 3/8"
drain line (provided) to the salt storage tank over-
flow elbow and secure in place with a hose clamp.
2Run 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 hose from Step 6 to the salt
storage tank overflow hose.
Step 8. Pressure Testing for eaks
To prevent air pressure in the water softener and
plumbing system, do the following steps exactly in
order:
1. Fully open two or more softened cold water faucets
nearby the water softener, located downstream from
the water softener.
2. Place the single bypass valve or 3 valve bypass in
"bypass" position. See Figures 7 & 8.
3. Fully 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 posi-
tion exactly 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 bub-
bles, 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
Step 6. Install Valve Drain Hose
NOTE: See valve drain options on pages 7 & 8.
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 rain requirements" section.
2. Run the drain hose (or a rigid line) to the floor drain.
Secure drain hose. This will prevent “whipping'' dur-
ing 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 good drain point for
this hose.. Avoid long drain hose runs, or ele-
vating the hose more than 8’ above the floor. continued on next page

Step 9. Add Water and Salt to the
Salt Storage Tank
1. Using a container, add about three gallons of clean
water into the salt storage tank.
2. Add Morton®Clean and Protect™or Clean and
Protect™Plus Rust efense™Pellets to the storage
tank.
NOTE: See Page 18 for additional information on
salt.
Step 10. Plug in the Power Supply
uring installation, the water softener wiring may be
moved or jostled from place. Check to 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 elec-
trical outlet that is not controlled by a switch and is
approved by local codes.
Step 11. Program the Controller
1. Install the softener’s top cover and salt lid.
2. Complete the programming steps on Pages 13-15.
Step 12. Sanitizing the System
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. Open salt lid, remove the brinewell cover and pour
about 3 oz. (6 tablespoons) of household bleach
into the softener brinewell. Replace the brinewell
cover.
2Make 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 sani-
tizing bleach into and through the water softener.
Any air remaining in the unit is purged to the drain.
4After the recharge has completed, fully open a cold
water faucet, downstream from the softener, and
allow 50 gallons of water to pass through the sys-
tem. 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.
Step 13. Restart the Water Heater
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
(Step 12) is over. Then, drain the water heater
(following instructions for water heater) until
water runs cold.

This softener setting is shipped in the OFF posi-
tion, which utilizes the maximum rated capacity
while most often achieving maximum salt effi-
ciencies. When installing this unit in the State of
California, you MUST turn this setting to the ON
position, which may initiate more frequent
recharges. However it will operate at 4000
grains per pound of salt or higher.
If you wish to turn the Salt Efficiency feature ON
( icon will show in the display), follow the
instructions on this page.

Recharge Now
At times of greater than normal water use, such as
when you have guests, you could run out of treated
water before the next scheduled recharge. If this
happens, you may want to initiate an immediate
regeneration, as follows:
1. Press and hold the RECHARGE button until the
words “RECHARGE NOW" flash in the display.
The system enters the fill cycle of regeneration right
away. “RECHARGE NOW” will flash during the
regeneration. When completed (in about 2 hours),
full water treatment capacity is restored.
NOTE: Avoid using hot water while the system is
regenerating, because the water heater will
refill with bypass hard water.
Recharge Tonight
If you do not want to start an immediate recharge, but
would like to schedule an extra recharge at the next
preset recharge time, do the following:
1. Press and release (do not hold) the RECHARGE
button.
The words “RECHARGE TONIGHT" flash in the dis-
play, and the water softener and filter will recharge at
the next preset recharge time (If you decide to cancel
the regeneration before it begins, press and release
the RECHARGE button once more, and “RECHARGE
TONIGHT” will disappear from the display). The
words “RECHARGE NOW" will flash during the
regeneration. When completed, full water condition-
ing capacity is restored.

Clean Feature
This feature is beneficial on water supplies containing
iron and/or high amounts of sediments (sand, silt, dirt,
etc.). When set to ON, a backwash and fast rinse
cycle will occur first, preceding the normal regenera-
tion sequence. This provides extra cleaning of the
resin bed before it is regenerated with the salt brine.
To conserve water, if your water supply does not con-
tain iron or sediments, be sure this feature is set to
OFF. The default is OFF.
To change between OFF and ON:
1. Press and hold the SELECT button until the screen
in Figure 27 is displayed.
3. Use the
p UP or q OWN buttons to change
between OFF and ON.

Cleansing Feature
The cleansing feature keeps larger particles of sedi-
ment from entering the home’s plumbing system. As
water passes through the softener, the larger sedi-
ment particles are collected in the integrated basket
and then rinsed to the drain before each regenera-
tion. The cleansing feature provides added protection
for water using appliances by reducing the chance of
larger particles entering the various products valves
and screens. The “Clean Feature” may be turned ON
to provide an extra backwash that will help keep the
cleansing screen clean. The default is OFF.
IMPORTANT: The cleansing feature is not intended to
replace pretreatment filtration. For
problem water applications, additional
sediment filtration is recommended.

Refilling with Salt
Lift the salt lid and check the salt storage level fre-
quently. If the water softener uses all the Morton®
Clean and Protect™or Clean and Protect™Plus Rust
efense™Pellets before you refill it, you will experi-
ence 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: We recommend using Morton®
Clean and Protect™or Clean and Protect™Plus Rust
efense™Pellets in the familiar yellow bag. For soft
water, nothing works harder. Guaranteed®.
Salt Not Recommended: Rock salt, high in impuri-
ties, block, granulated, table, ice melting, ice cream
making salts, etc., are not recommended.
Salt with Iron Removing Additives: Some salts
have an additive to help a water conditioner handle
iron in a water supply. For this we recommend
Morton®Rust Remover Super Pellets®in the green bag.
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. o not use any sharp or pointed objects as
you may puncture the brine tank. o not try to break
the salt bridge by pounding on the outside of the salt
tank. You may damage the tank.
R utine Maintenance
Power Outage Memory
If electrical power to the softener is interrupted, the
time display is blank, but the electronic controller
keeps correct time for several hours. When power is
restored, you must 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 out-
age, the softener 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
clock to the correct time of day.
NOTE: If the water softener was regenerating when
power was lost, it will now finish the cycle.

R utine Maintenance
Protect the Water Softener from
Freezing
If the softener is installed where it could freeze (sum-
mer 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 pres-
sure 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. Push the bypass valve body toward the softener (as
shown in Figure 15) and 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 36).
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. o 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.

Cleaning the Nozzle & Venturi
A clean nozzle & venturi (See Figure 35) 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
plugged with sand, silt, dirt, etc., the water softener will
not work, and hard water will result.
Nozzle & Venturi isc
IMPORTANT: Be sure small hole in the gasket is cen-
tered directly over the small hole in the nozzle & ven-
turi housing. Be sure the numbers are facing up.
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 noz-
zle & venturi). Then, holding the nozzle & venturi
housing with one hand, un screw the cap. o 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. o not
scratch, misshape, etc., surfaces of the nozzle & ven-
turi.
Carefully 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 com-
pletely 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.
