Water Softener Installation & Operation Manual 5
Specifications & Performance Claims
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.
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-
i
mize the amount of regenerant brine and water used in their operation.
T
his 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
s
ustained 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.
*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.
***Canada working pressure: 1.4 - 7.0 kg/cm².
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.

Water Softener Installation & Operation Manual
= 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
l
aws.
= 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 prop-
er disposal of this equipment.
Before You Start
Water Conditioning Information
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.

1-1/2”
air gap
Floor Drain
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.

Location Requirements
C
onsider all of the following when selecting an installa-
tion location for the water softener.
= Do not locate the water softener where freezing
t
emperatures 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, 60Hz 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 non-
metallic parts.

Installation Requirements
Valve Drain Requirements
U
sing 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.
Pipe fittings must be 3/4” minimum.
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
installation adaptors and single bypass
valve. Soldering heat will damage the
adaptors and valve.

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. 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 (See Figure 11).
Step 3. 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.
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. (Optional) Install the Motorized Water Shutoff Valve
If you purchased the optional water shutoff valve,
install it in the plumbing upstream of the softener inlet.
Figure 9B shows installation with the shutoff valve
immediately upstream of the bypass valve inlet, using
one of the softener’s installation adaptors and the 1”
NPT nipple provided with the shutoff valve.
The shutoff valve may also be installed in the plumbing
farther upstream of the softener, making sure that the
10 foot long cable will reach the softener’s electronic
control board (See Figure 9C). The shutoff valve’s
inlet and outlet are female 1” NPT. Support the weight
of the shutoff valve.
After completing plumbing, make sure that the water
softener is not powered up, and plug the cable from
the shutoff valve into the corresponding connector on
the electronic control board (See Fig. 9C or Schematic
on Page 26).
CAUTION: Do not place fingers into the motorized
shutoff valve when it is plugged into the electronic con-
troller.
NOTE: The shutoff valve may be operated manually
by pulling out and turning the knob on the shutoff valve
body (See Fig. 64 on Page 27), although there is no
need to do this when installing.

Step 5. 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
t
he 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 6. Cold Water Pipe Grounding
C
AUTION: 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.
FIG. 14
Ground
Wire
Clamp (2)
Step 8. 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-
f
low elbow and secure in place with a hose clamp.
2 Run 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 7 to the salt
storage tank overflow hose.
Step 9. Pressure Testing for Leaks
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

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

Step 7. 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 Drain 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.

Step 10. 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 Defense
™
Pellets to the storage
tank.
NOTE: See Page 19 for additional information on
salt.
Step 11. Plug in the Power Supply
During 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 12. Program the Controller
1
. Install the softener’s top cover and salt lid.
2
. Complete the programming steps on pages 14-16.
Step 13. Sanitizing the Softener
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.
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 sani-
tizing 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 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 14. 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 13) is over. Then, drain the water heater
(following instructions for water heater) until
water runs cold.

SELECT button several times until one of them does.
1. Press the
p
UP or
q
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 22 for more
information on salt types.
2. When the correct salt type is displayed, press the
SELECT button, and the display will change to
show the “Set Salt Level” screen.
FIG. 22

UP or
q
DOWN buttons to set the
hardness of your water supply, in grains per gallon.
The default is 25.
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

flash in the display (Fig. 25) to remind you to add salt.
Extra Recharge
S
ometimes, a manually initiated recharge (regenera-
tion) may be desired, or needed. Two examples are:
= You have used more water than usual (guests visit-
i
ng) 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

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

Breaking a Salt Bridge
S
ometimes, 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 dis-
tance 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 out-
side of the salt tank. You may damage the tank.

Routine 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 57).
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.

Cleaning the Nozzle & Venturi
A clean nozzle & venturi (See Figure 56) is a necessity
f
or 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.

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. 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 & 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.

Water Softener Installation & Operation Manual
Error Codes 01, 02, 03, 04 & 05:
These are the water softener error codes unrelated to
the optional water shutoff valve. While one is in the
display, the SELECT button remains operational so
the service person can perform the Manual Advance
Diagnostics, below, to further isolate the problem.
Procedure for removing error codes 01 through 05
from display:
1. Unplug power supply from electrical outlet.
2. Correct problem.
3. Plug power supply back in.
4. Wait 8 minutes. The error code will return if
the problem was not corrected.
Error Codes 07, 08 & 09:
These error codes indicate a problem with the option-
al water shutoff valve. Make sure that the water shut-
off valve is still plugged into the water softener’s con-
trol board. To clear one of these codes from the dis-
play, press the RECHARGE button and hold for 3
seconds. If the error code is displayed again after a
minute or two, the water shutoff valve probably needs
to be replaced.
Manual Advance Diagnostics
Use the following procedures to advance the water
softener through the regeneration cycles to check
operation.
Remove the top cover to expose the valve and ob -
serve 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:
000 (steady) = Soft water not in use, and no flow
through the meter.
Open a nearby soft water faucet.
000 to 140 (continual) = Repeats for each gallon
of water passing through
the meter.
4. Use the RECHARGE button to manually advance
the valve into each cycle and check correct switch
operation.
NOTE: Be sure water is in contact with the salt, and
not separated by a salt bridge (See "Breaking
A Salt Bridge" section).
5. While in this diagnostic screen, the following infor-
mation is available and may be beneficial for vari-
ous reasons. This information is retained by the
computer from the first time electrical power is
applied to the electronic controller.
a. Press the
p
UP button to display the number of
days this electronic control has had electrical
power applied.
b. Press the
q
DOWN button to display the number
of regenerations initiated by this electronic con-
trol since the code number was entered.
6. Press and hold the SELECT button until the model
code (o45) shows in the display. This code identi-
fies the softener model. If an incorrect model code
is displayed, the softener will operate on incorrect
configuration data.
7. To change the code number, press the
p
UP or
q
DOWN button until the correct code shows.
8. To return to the present time display, press the
SELECT button.

Troubleshooting
Resetting to Factory Defaults
T
o reset the electronic controller to its factory default
for all settings (time, hardness, etc.):
1. Press the SELECT button and hold it until the dis-
p
lay changes twice to show “CODE” and the flash-
ing model code.
2. Press the
p
UP button (a few times, if necessary)
to display a flashing “SoS”.
3. Press the SELECT button, and the electronic con-
troller will restart.
4. Set the present time, hardness, etc., as described
on pages 14-16.
This check verifies proper operation of the valve
motor, brine tank fill, brine draw, regeneration flow
rates, and other controller functions. Always make
the initial checks, and the manual initiated diagnos-
tics.
NOTE: The electronic control display must show a
steady time (not flashing). If an error code
shows, first press the SELECT button to enter
the diagnostic display.
1. Press the RECHARGE button and hold in for 3
seconds. RECHARGE begins to flash as the soft-
ener’s valve advances from the service to fill posi-
tion. Remove the brinewell cover and, using a
flashlight, observe fill water entering the tank.
If water does not enter the tank, look for an
obstructed nozzle, venturi, fill flow plug, brine tub-
ing, or brine valve riser pipe.
2. After observing fill, press the RECHARGE button to
move the softener’s valve into the brine position. A
slow flow of water to the drain will begin. Verify
brine draw from the brine tank by shining a flash-
light into the brinewell and observing a noticeable
drop in the liquid level. This may take 15 to 20
minutes.
Manual Advance Regeneration Check
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.
= Restriction in valve drain, causing a back-pres-
sure (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, an elevated
drain hose may cause back pressure, stop-
ping brine draw.
3. Press the RECHARGE button to move the soften-
er’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 vol-
ume.
An obstructed flow indicates a plugged top distribu-
tor, backwash flow plug, or drain hose.
4. Press the RECHARGE button to move the soften-
er’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 posi-
tion, press the RECHARGE button.

Water Softener Installation & Operation Manual 27
The Motorized Water Shutoff Valve (sold separately)
may be used with this Morton
®
Wi-Fi connected water
softener and the iQua™ app to remotely turn off the
home’s water supply. For example, you may want to
t
urn off the water when going away on vacation.
Install the motorized shutoff valve in the plumbing,
upstream of the softener (see page 10), and plug the
cable into the softener’s electronic control board with
the power off (see page 10 and Figure 63).
On the iQua™ app, near the bottom of the softener’s
main dashboard, there is a line labeled “Water
Control” with a button that, when pressed, alternates
between “Water On” and “Water Off”. If you receive
an alert indicating continuous water flow, you can use
this control to remotely shut off the water.
The system default for triggering a continuous water
flow alert is 20 minutes of flow at 0.4 gallons per
minute or higher. The time and water flow trigger val-
ues may also be adjusted in the “Alerts” section.
To manually operate the motorized water shutoff
valve, pull out the round knob on the valve and turn it
until the red line in the sight glass matches the
desired (open or closed) position. See Figure 64. If
you manually operate the valve, the app’s “Water
Control” feature will be disabled until you reset it by
clicking “Yes” next to the “Regain Control?” prompt.
