Recommended 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. Be sure
the addition of a pressure reducing valve will not
reduce the flow to less than the 3 gallons per minute.
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 circuit breaker or
fuse.
This system is not intended to be used for treating
water that is microbiologically unsafe or of unknown
quality without adequate disinfection before or after
the system.
European Directive 2002/96/E requires all
electrical and electronic equipment to be
disposed of according to Waste Electrical
and Electronic Equipment (WEEE) require-
ments. 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.
Follow the installation instructions carefully. Failure to
install the water softener properly voids the warranty.
Before you begin installation, read this entire manual.
Then obtain all the materials and tools you will need
to make the installation.
Check local plumbing and electrical codes. The
installation must conform to them.
Use only lead-free solder and flux for all sweat-sol-
der connections as required by state and federal
codes.
Use care when handling the water softener. Do not
turn upside down, drop, or set on sharp protrusions.
Do not locate the water softener where freezing tem-
peratures occur. Do not attempt to treat water over
120°F. Freezing, or hot water damage voids the war-
ranty.
Avoid installing in direct sunlight. Excessive sun heat
may cause distortion or other damage to non-metallic
parts.
The water softener requires a minimum water flow of
3 gallons per minute at the inlet.
The parts required to assemble and install the water
softener are included with the unit. Thoroughly check
the water softener for possible 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.

This system, when containing EcoWater Systems resin part number 0502272 in the
amount listed above, conforms to NSF/ANSI 44 for the specific performance claims
as verified and substantiated by test data.
This softener has a rated softener efficiency of not less than 3,350 grains of total hardness exchange per pound of
salt (based on sodium chloride). This softener has been proven to deliver soft water for at least ten continuous min-
utes 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 effi-
ciency 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.

SYSTEMS Before Starting Installation
WHERE TO INSTA THE SOFTENER
= To soften all water in the home, install the water
softener close to the water supply inlet, upstream
of all other plumbing connections, except outside
water pipes. Outside faucets should remain on
hard water to conserve salt and softening capacity.
= Place the softener near a floor drain, or other
acceptable drain point (laundry tub, sump, stand-
pipe, etc.) to carry away regeneration discharge
water.
= onnect the softener to the main water supply
pipe UPSTREAM OF the water heater. DO NOT
RUN HOT WATER THROUGH THE SOFTENER.
The temperature of water passing through the sof-
tener must be less than 120°F.
= Do not install the softener in a place where it could
freeze. Damage caused by freezing is not cov-
ered by the warranty.
= Put the softener in a place water damage is least
likely to occur if a leak develops. The manufactur-
er will not repair or pay for water damage.
= A 120V, 60 Hz electrical outlet, to plug the included
power supply into, is needed near the softener.
Be sure the electrical outlet and power supply are
in an inside location, to protect from wet weather.
= If installing in an outside location, you must take
the steps necessary to assure the softener, instal-
lation plumbing, wiring, etc., are as well protected
from the elements, contamination, vandalism, etc.,
as when installed indoors.
= Keep the softener out of direct sunlight. The sun's
heat may soften and distort plastic parts.

= ALWAYS install an EcoWater Systems bypass valve,
or a 3-valve bypass system. Bypass valves let you
turn off water to the softener for repairs if needed,
but still have water available to the house pipes.
= Plastic inlet and outlet fittings are included with the
softener, which allow water flow equivalent to 1 inch
nominal pipe. To maintain maximum valve flow, 1”
pipes to and from the softener fittings are recommend -
ed. Do not reduce the pipes to less than 3/4” size.
= Use copper, brass or PEX plastic pipe and fittings.
= Drain hose, 1/2” inside diameter minimum, is needed
for the valve drain.
= If a rigid valve drain is needed, to comply with
plumbing codes, you can buy the parts needed to
connect a 1/2” minimum copper tubing drain.
NOTE: The ommonwealth of Massachusetts plumbing
code 248- MR shall be adhered to. A licensed plumber
shall be used for this installation.

SYSTEMS Media oading
MEDIA OADING
Model ESS1102XR32, as manufactured, contains no
media. Before plumbing the system, load media (See
table on Page 13 for amounts):
1. Move the system into installation location and set it
on a flat, level surface.
2. Take off the unit’s top cover and unplug the wiring
connections between the valve and the control
board (PWA).
3. Remove retainer clips and clamp sections from the
tank neck and carefully lift the valve off the tank.
4. Remove the top distributor from the tank neck,
leaving the bottom distributor (including riser pipe)
in place. enter the distributor in the tank.
5. With a pail or hose, fill the tank with about 12” of
water. The water acts as a cushion to protect the
bottom distributor while filling the tank with gravel
and media.
6. over the top end of the distributor riser pipe with a
clean rag, to keep gravel and media out (See Fig. 4).
7. Using a larger neck funnel, add the gravel (if used)
and media in that order. Be sure the distributor
remains centered. Use water sparingly to speed
flow through the funnel (It may become necessary
to siphon water from the bottom of distributor if
tank becomes full of water).
8. Flush the tank opening with water to clean media
particles from the top of the tank. Uncover the bot-
tom distributor riser pipe.
9. Finish filling the tank with water, up to the top of
the tank.
IMPORTANT: Be sure to fill with water. This will elim-
inate air space and prevent excessive
air-head pressure when tank is pres-
surized.
10. Install the o-ring seals and top distributor exactly
as shown in Figure 5. If the o-rings need lubrica-
tion, use a high quality silicone grease.
11. Lower the valve assembly onto the tank, centering
over the riser tube. Push downward, against the
o-ring, and install the clamp sections, securing
with the retainer clips.
12. Reconnect the wiring between the valve and the
control board (PWA).

the house pipes.
2. INSTA BYPASS VA VE AND/OR
P ASTIC INSTA ATION ADAPTORS:
a. If installing a single bypass valve, push the bypass
valve, with lubricated o-ring seals in place, into the
valve inlet and outlet ports (See Figure 7).
- OR -
b. If installing a 3-valve bypass system, slide plastic
installation adaptors, with lubricated o-ring seals in
place, into the valve inlet and outlet ports, respec-
tively (See Figure 7).
c. If adding a turbine to the system, be sure the tur-
bine and support are in place in the valve outlet, as
shown in Figure 8.
d. Snap the two large plastic clips in place on the inlet
and outlet ports, from the top, down (See Figure 9).
Be sure they snap into place. Pull on the bypass

are held securely in place.
3. COMP ETE P UMBING TO AND FROM
THE SOFTENER
Using the “Typical Installation Illustration” on page 8
as a guide, observe all of the following cautions while
you connect inlet and outlet plumbing:
= Be sure incoming, hard water is directed to the
valve IN ET port.
= Be sure to install bypass valve(s).
= If making a soldered copper installation, do all
sweat soldering before connecting pipes to the fil-
ter fittings. Torch heat will damage plastic parts.
= Use pipe joint compound on all external pipe
threads.
= When turning threaded pipe fittings onto plastic fit-
tings, use care not to cross-thread.
= Support inlet and outlet plumbing in some manner
(use pipe hangers) to keep the weight off of the
valve fittings.

6. BRINE TANK ASSEMB Y
a. Position the brinewell in the recess at the bottom of
the brine tank and attach it to the side with the
screw and washer provided (See Figure 12).
b. Lower the brine valve into the brinewell until it is
sitting on the bottom. Route the brine tube out of
the brinewell through the top slot, and put the
brinewell cover into place (See Figure 12).
4. CO D WATER PIPE GROUNDING
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 6,
will maintain ground continuity. If you use the plastic
bypass, continuity is broken. To restore the ground,
do either step 4a or 4b following.
a. Use the EcoWater ground clamp kit (not included)
to make a jumper across the inlet and outlet pipes
(See Figure 11).
b. Install a #4 copper wire across the removed sec-
tion of main water pipe, securely clamping at both
ends – parts not included.
5. INSTA VA VE DRAIN HOSE
a. Take a length of 1/2” inside diameter hose and
attach to the valve drain fitting, securing it with a
hose clamp (See Figure 6 on page 8).
b. Locate the other end of the hose at a suitable drain
point (floor drain, sump, laundry tub, etc.). heck
and comply with local codes. Refer to Figure 6 on
page 8 if codes require a rigid pipe drain run.
IMPORTANT: Use high quality, thick wall hose that
will not easily kink or collapse. The
softener will not backwash properly if
water cannot exit this hose during
recharges.
c. Tie or wire the hose in place at the drain point.
Water pressure will cause it to whip during the
backwash portion of the recharge cycle. Also pro-
vide an air gap of at least 1-1/2” between the end
of the hose and the drain point. An air gap pre-
vents possible siphoning of sewer water, into the
softener, if the sewer should back up.
d. If raising the drain hose overhead is required to get
to the drain point, do not raise higher than 8 feet
above the floor. Elevating the hose may cause a
back pressure that could reduce backwash flow
and proper resin bed cleaning.

7. INSTA BRINE TANK OVERF OW HOSE
This drain is for safety only. If the brine tank should
over-fill with water, the excess is carried to the drain.
a. Take the rubber grommet and hose adaptor elbow
from the parts bag. Push grommet into the corre-
sponding hole in the back wall of the brine tank.
Then insert the larger diameter end of the elbow
through the grommet.
b. Attach a length of 1/2” inside diameter hose to the
drain elbow, installed in the previous step. Use a
hose clamp to hold it in place.
c. Locate the other end of the hose at the drain point.
Do not elevate this hose higher than the elbow on
the brine tank. Do not tee this hose to the valve
drain hose.

b. onnect the brine tube to the nozzle/venturi
assembly using the ferrule nut provided (See
Figure 13).
9. PRESSURE TESTING FOR EAKS,
PROGRAMMING THE CONTRO ER &
RINSING THE MEDIA
To prevent excessive air pressure in the water
softener and plumbing system, do the following
steps EXACT Y in order:
a. Fully open two or more softened cold water
faucets nearby the water softener.
b. Place the bypass valve(s) in bypass position (See
Figures 2 & 6).
c. Fully open the main water supply valve. Watch
until the flow from the opened faucets becomes
steady, with no spurting or air bubbles.
d. After about three minutes, open a hot water faucet
for one minute, or until all air is expelled.

f. Make sure the softener’s valve drain hose is
hooked up and the open end directed to a floor
drain, laundry tub or other suitable type of drain.
g. Make sure the softener’s bypass valve is in the
bypass position.
h. Plug in the power supply.
i. Program the electronic controller: Follow the
steps on Pages 13 & 14 (for softeners) or Page 16
(for filters) to program the electronic controller with
basic operating information, such as time and water
hardness. After completing these steps, continue
with “j. Start a recharge”, below.
j. Start a recharge: Press the RE HARGE button
and hold for 3 seconds, until “Recharge Now” flash-
es in the display and you hear the valve motor run
as the softener begins recharging.
k. Once the unit is in backwash, place bypass
valve(s) into the service position, as follows:
(1) SINGLE BYPASS VALVE: Slowly move the
valve stem toward service position, pausing sev-
eral times to allow the unit to pressurize slowly.
(2) 3-VALVE BYPASS: Fully close the bypass
valve and open the outlet valve. Slowly open
the inlet valve, pausing several times to allow the
unit to pressurize slowly.
l. Let the softener complete the backwash and fast
rinse cycles (takes 10-12 minutes). When the
recharge cycle ends, the softener valve returns to
the service position.

a. Using a pail or garden hose, add about 3 gallons of
water into the brine tank. DO NOT pour into the
brinewell.
b. Add salt to the brine tank. It is recommended to fill
the brine tank no more than 1/2 full. Level the salt
when finished adding. You can use most water
softener salts, but it must be clean.
Recommended nugget, pellet or coarse solar salts
have less than 1% impurities.
NOTE: See page 20 for additional information on salt.

SYSTEMS Installation & Sanitizing
11. SANITIZING THE WATER SOFTENER
are is taken at the factory to keep your EcoWater
Systems water softener clean and sanitary. However,
during shipping, storage, installing and operating,
bacteria could get into the unit. For this reason, sani-
tizing as follows is suggested* when installing.
a. Remove the brinewell cover and pour about 1-1/2
oz. (2 to 3 tablespoons) of common household
bleach into the softener’s brinewell. Replace the
brinewell cover.
b. Make sure the bypass valve is in the service posi-
tion.
c. Start a recharge: Press the RE HARGE button
and hold for 3 seconds, until “Recharge Now”
flashes in the display and you hear the valve motor
run as the softener begins recharging. This
recharge draws the sanitizing bleach into and
through the softener. Any air remaining in the unit
is purged to the drain.
d. 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. lose
the faucet.
12. RESTART THE WATER HEATER
Turn on the electric or fuel supply to the water heater,
and light the pilot, if applies.
NOTE: The water heater is filled with hard water and,
as hot water is used, it refills with softened water. In
a few days, the hot water will be fully conditioned. To
have fully conditioned hot water immediately, wait
until the recharge (Step 11) is complete, then drain
the water heater until water runs cold.
*Recommended by the Water Quality Association. On
some water supplies, the EcoWater Systems unit may need
periodic disinfecting.

Before going on vacation, or any other long absence,
press and release (do not hold) the RE HARGE but-
ton, so “VA ” begins flashing in the display.
In vacation mode the electronic controller continues to
keep time, but recharges will not occur using water

POWER OUTAGE MEMORY
If electrical power to the softener/filter’s control is lost,
internal memory will maintain most settings such as
the hardness and recharge time. However, unless
the power outage was very brief, the clock’s present
time will need to be reset. During a power outage,
the display will be blank and the unit will not
recharge. When electrical power is restored:
1. heck the display.
2a. If the present time is displayed steadily (not flash-
ing), the controller did not lose time and you do
not need to reset the clock.
2b. If a time is flashing in the display, then the clock
needs to be reset to the correct present time.
See “Set Present Time of Day” on page 13. The
flashing display is to remind you to reset the
clock. If you do not reset the clock, then
recharges will most likely occur at the wrong time
of day.
NOTE: If the unit was recharging when power was
lost, it will finish the cycle when power returns.

ECOWATER
SYSTEMS Routine Maintenance
REFI ING WITH SA T
If the softener uses all the salt before more is added,
hard water will result. Remove the brine tank lid and
check the salt level frequently. Until you have estab-
lished a refilling routine, check the salt every 2 or 3
weeks. Be sure that the brinewell cover is on when
adding salt.
NOTE: In humid areas it is best to keep the salt level
less than half full and refill more often.
RECOMMENDED SA T: ube, pellet, coarse solar,
etc., water softener salt is recommended. This type
of salt is high purity evaporated crystals, sometimes
formed and pressed into briquets. It has less than
1% insoluble (not dissolvable in water) impurities.
lean, high grade rock salts are acceptable, but may
require frequent brine tank cleaning to remove the
“sludge” residue (insolubles) collecting at the bottom
of the tank.
POTASSIUM CH ORIDE: If you choose potassium
chloride (K l) salt instead of standard sodium chlo-
ride (Na l) water softener salt as a regenerant:
1) The hardness setting must be increased by 25%.
2) Place only one bag of potassium chloride (K l) into
your water softener at a time. The salt storage
tank should never contain more than 60 pounds of
K l.
SA T NOT RECOMMENDED: Rock salt high in
impurities, block, granulated, table, ice melting, or ice
cream making salts, etc., are not recommended.
SA T WITH IRON REMOVING ADDITIVE: Some
salts have an additive to help a water softener handle
iron in the water supply. Although this may help keep
the resin bed clean, it may also release corrosive
fumes that will weaken and shorten the life of some
EcoWater Systems softener electronic parts. Iron Out
salt is safe to use on two-tank models.
BREAKING A SA T BRIDGE
Sometimes a hard crust or salt “bridge” forms in the
brine tank. This 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
whether there is a salt bridge. A bridge may be
underneath loose salt. The following is the best way
to check for a salt bridge:
Salt should be loose all the way to the bottom of the
tank. Hold a broom handle, or like tool, up to the
softener’s brine tank, as shown in Figure 44. Make a
pencil mark on the handle 1” - 2” below the top of the
rim. Then, carefully push it 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.
arefully push into the bridge in several places to
break it. Do not try to break the salt bridge by
pounding on the outside of the salt tank. You
may damage the tank.
