S ecifications & 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 ( .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 treatment system 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.

*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.
**Typical residential chlorine concentration is 0.5 to 1.0 ppm.
§ From independent laboratory test data.
This system conforms to NSF/ANSI Standards 42 & 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.

Safety Guides
=The water treatment system requires a minimum water flow of 3 gallons (11.4 L) per minute at the inlet.
Maximum allowable inlet water pressure is 100 psi (7.0 kg/cm2). If your house water pressure is over the maxi-
mum, install a pressure reducing valve in the water supply pipe to the system (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.
=Temperature of the water supply to the softener must be 40-100°F (5-38°C). o not install on hot water.
=The water treatment system works on 24V C electrical power, supplied by a direct plug-in power supply (includ-
ed). 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

Water Treatment 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 treatment system will reduce moder-
ate 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 system 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 treatment system 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 treatment system will not remove colloidal
iron. In some instances, treatment may improve col-
loidal 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 treatment system 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 up -
stream of the system 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.
The parts required to assemble and install the water
treatment system are included with the unit.
Thoroughly check the water treatment system for pos-
sible shipping damage and parts loss. Also inspect
and note any damage to the shipping carton.
Remove and discard (or recycle) all packing materials.
To avoid loss of small parts, we suggest you keep the
small parts in the parts bag until you are ready to use
them.

PLUMBING CODES
All plumbing must be completed in accordance with
national, state and local plumbing codes.
AIR GAP REQUIREMENTS
A drain is needed for regeneration water (See Figure
3). A floor drain, close to the water treatment system,
is preferred. A laundry tub, standpipe, etc. are other
drain options. Secure valve drain hose in place.
Leave an air gap of 4 cm between the end of the hose
and the drain. This gap is needed to prevent backflow
of sewer water into the water treatment system. o
not put the end of the drain hose into the drain.

LOCATION REQUIREMENTS
Consider all of the following when selecting an installa-
tion location for the water treatment system.
=o not locate the water treatment system where
freezing temperatures occur. Temperature of the
water supply to the softener must be 40-100°F
(5-38°C). o not install on hot water. Freezing
temperatures or hot water damage voids the war-
ranty.
=To treat all water in the home, install the water treat-
ment system 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 treated 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 Require -
ments" and "Valve rain Requirements" sections.
=The water treatment system works on 24V C elec-
trical power, supplied by a direct plug-in power supply
(included). Provide nearby a 120V, 60Hz electrical
outlet in accordance with national and local codes.
=Always install the water treatment system between
the water inlet and water heater. Any other installed
water conditioning equipment should be installed
between the water inlet and water treatment system
(See Figure 4 below).
=Avoid installing in direct sunlight. Excessive sun
heat may cause distortion or other damage to non-
metallic parts.

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 1.25 cm minimum tube) and
1.25 cm tubing from your local hardware store. Plumb
a rigid drain as needed (See Figure 6).
NOTE: Avoid drain hose runs longer than 9 meters.
Avoid elevating the hose more than 2.5 meters
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.

Installation Instructions
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.
ASSEMBLY
1. EcoPure models are factory assembled. uring
installation, unsnap and remove the top cover,
together with the salt lid, to expose the water treat-
ment system valve assembly. Set them aside to
prevent damage. Check the brinewell to be sure it
is secured and vertical (See Figure 13).
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 2 cm diameter hole in the back of the salt
storage tank wall.
MOVE THE SYSTEM INTO PLACE
1. Move the water treatment system 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 system.
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 treatment system 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 system valve
as far as it will go. Snap the two large holding clips
into place, from the top down as shown in Figures
11 & 12.
IMPORTANT: Be sure the clips snap firmly into place
so the single bypass valve will not pull
out.

NOTE: Be sure all 3 tabs of the clip go through the matching
holes on the water treatment system valve inlet or
outlet, and fully into the channel on the single bypass
valve. Make sure that the tabs are fully seated.
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 treatment system valve. Be sure to keep fit-
tings fully together, and pipes squared and straight.
Be sure hard water supply pipe goes to the water
treatment system valve inlet side.
NOTE: Inlet and outlet are marked on the water treat-
ment system valve. Trace the water flow direc-
tion 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 treatment system valve inlet
and outlet. Undue stress from mis-
aligned or unsupported plumbing may
cause damage to the valve.
Complete the inlet and outlet plumbing for the type of
pipes you will be using.
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.

Installation Instructions
INSTALL VALVE DRAIN HOSE
NOTE: See valve drain options on pages 6 & 7.
1. Measure, cut to needed length and connect the 9.5
mm drain line (provided) to the water treatment sys-
tem 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 4 cm min-
imum air gap to prevent possible sewer water
backup. See “Air Gap Requirements" section.
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 2.5 meters above
the floor.
INSTALL SALT STORAGE TAN OVERFLOW
HOSE
1. Measure, cut to needed length and connect the 9.5
mm drain line (provided) to the salt storage tank
overflow elbow and secure in place with a hose
clamp.
2Route 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 treat-
ment system, do not connect the system
valve drain tubing to the salt storage
tank overflow hose.
ADD WATER AND SALT TO THE SALT
STOR AGE TAN
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
uring installation, the water treatment system 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.
NOTE: The water heater is filled with hard water and,
as hot water is used, it will refill with treated
water. In a few days, the hot water will be fully
treated. To have fully treated hot water imme-
diately, wait until the initial recharge is over.
Then, drain the water heater (following instruc-
tions for water heater) until water runs cold.
PROGRAM THE CONTROLLER
1. Install the system’s top cover and salt lid.
2. Complete the programming steps on pages 12 & 13.
RINSE OUT CARBON FINES
Small particles of carbon filtration material are generat-
ed during manufacturing and shipping, which will exit
the media tank with the first water flow. These carbon
“fines” are not harmful, but give the water a gray color
and should be rinsed down the drain before any water
from the system is directed to the home’s faucets or
water heater.
CAUTION: To avoid water or air pressure damage to
system inner parts, and to flush pipe chips
or other residue from the water pipes, be
sure to do the following steps exactly as
instructed.
1. Make sure the water treatment system’s valve drain
hose is hooked up and the open end directed to a
floor drain, laundry tub or other suitable type of
drain.
2. The system should be connected to electrical power.
3. Place bypass valve(s) in “bypass” position (see
Figures 7 & 8). On a single valve, slide the stem
inward to bypass. On a 3-valve bypass, close the
inlet and outlet valves and open the bypass valve.
4. Fully open the house main water pipe shutoff valve.
5. Initiate a regeneration by pressing and holding for 3
seconds the RECHARGE button (see Figure 16 on
page 12). The valve motor will start running and the
valve will advance to the “Fill” position.
6. After you hear the valve motor stop running (valve
in “Fill” position), press, but do not hold, the
RECHARGE button. The valve will advance to the
“Brine” position.

7. After you hear the valve motor stop running (valve
in “Brine” position), press, but do not hold, the
RECHARGE button. The valve will advance to the
“Backwash” position.
8. Once the unit is in backwash, place bypass valve(s)
in SERVICE, EXACTLY as follows:
a. Single Bypass Valve: Slowly, slide pull the valve
stem outward toward service, pausing several times
to allow the system to pressurize gradually.
b. 3-Valve Bypass: Fully close the bypass valve and
open the outlet valve. Slowly open the inlet valve,
pausing several times to allow the system to pres-
surize gradually.
9. Let the water treatment system complete the back-
wash and fast rinse cycles (takes about 20 min-
utes). When the regeneration ends, the system’s
valve returns to the service position.
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 90 ml (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 sanitiz-
ing 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 190 liters 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 treated
water. In a few days, the hot water will be fully
treated. To have fully treated hot water imme-
diately, wait until the initial recharge (previous
step) is over. Then, drain the water heater (fol-
lowing instructions for water heater) until water
runs cold.
TEST FOR LEA S
To check for leaks, complete the following steps:
1. Fully open two nearby cold water faucets down-
stream from the water treatment system.
2. Observe steady water flow from both open faucets.
3After about three minutes, open a hot water faucet
for about one minute, or until all air is expelled, then
close.
4. Close both cold water faucets.
5. Check your plumbing work for leaks, and fix right
away if any are found. Be sure to observe previous
caution notes.
NOTE: If this procedure is performed on a new sys-
tem, water coming from the taps may initially
be discolored. This normally occurs the first
time water runs through the resin bed. The
discolored water is not harmful, and the discol-
oration will not last more than a few minutes.

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.

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.

Features / O tions
POWER OUTAGE MEMORY
If electrical power to the water treatment system is
lost, “memory'' built into the timer circuitry will keep all
settings for several hours. While the power is out, the
display is blank and the system will not regenerate.
When electrical power is restored, the following will
occur.
You have to reset the present time only if the display
is flashing. The HAR NESS and RECHARGE TIME
never require resetting unless a change is desired.
Even if the clock is incorrect after a long power out-
age, the system operates 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 cor-
rect time of day.
NOTE: If the water treatment system was regenerat-
ing when power was lost, it will now finish the
cycle.
Routine Maintenance
ADDING SALT
Lift the salt lid and check the salt storage level fre-
quently. If the water treatment system uses all the salt
before 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.
BREA ING 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 treatment system. Measure the
distance from the floor to the rim of the water treat-
ment system. Then, gently 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. Gently push into the bridge in sev-
eral places to break it. o not use any sharp or point-
ed 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.

CLEANING THE NOZZLE & VENTURI
A clean nozzle & venturi (See Figure 35) is a necessity
for the water treatment system 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 system
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 treatment system’s top cover. Put the bypass
valve(s) into the bypass position. Be sure the system
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. 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.
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 water treatment system to reduce water
level in the tank. This will also assure that the system
is completely recharged and ready to provide softened
water again. Check the water level in the tank by look-
ing down the brinewell. If the water level does not
drop after a recharge, the problem has not been
resolved. Call 1-800-693-1138.
PROTECT THE WATER TREATMENT SYS-
TEM FROM FREEZING
If the water treatment system is installed where it could
freeze (summer cottage, lake home, etc.), you must
drain all water from it to stop possible freeze damage.
To drain the system:
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 treated water pipes to vent
pressure in the system.
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. Slide
open the salt lid and remove the water treatment
system’s top cover. Take off both drain hoses if they
will interfere with moving the system into position
over the drain.
5. Carefully remove the large holding clips at the water
treatment system inlet and outlet. Separate the sys-
tem from the plastic installation adaptors, or from
the bypass valve.
6. Lay a piece of 5 cm thick board near the floor drain
(See Figure 36).
7. Move the water treatment system 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 system’s weight to rest on
the inlet and outlet fittings or they may break.
8. Tip the bottom of the water treatment system up a
few centimeters and hold until all water has drained.
Leave the system laying like this until you are ready
to use it. Plug the inlet and outlet with clean rags to
keep dirt, bugs, etc. out.
