SAFETY GUIDES
Follow the installation instructions carefully. Failure to install the EcoWater softener properly voids the war-
ranty.
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. In Massachusetts,
plumbing codes of Massachusetts shall be adhered to. Consult with your licensed plumber.
Use only lead--free solder and flux for all sweat---solder connections, as required by state and federal
codes.
Use care when handling the EcoWater softener. Do not turn upside down, drop, or set on sharp protrusions.
Do not locate the EcoWater softener where freezing temperatures occur. Do not attempt to treat water over
120˚F. Freezing, or hot water damage voids the warranty.
A void installing in direct sunlight. Excessive sun heat may cause distortion or other damage to non---metallic
parts.
The EcoWater softener requires a minimum water flow of 3 gallons per minute at the inlet. Maximum allow-
able 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.)
The EcoWater softener works on 24 volt --60 hz electrical power only. Be sure to use the included trans-
former and plug it into a nominal 120V, 60 cycle household outlet that is grounded and properly protected by
an overcurrent device such as a circuit breaker or fuse. If transformer is replaced, use only the authorized
service Class II, 24 volt, 10 VA transformer.
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/EC requires all electrical and electronic equipment to be disposed of ac-
cording to Waste Electrical and Electronic Equipment (WEEE) requirements. This directive or similar
laws are in place nationally and can vary from region to region. Please refer to your state and local laws
for proper disposal of this equipment.

These systems conform to NSF/ANSI 44 for the specific capacity claims as verified and substantiated by test data.
Intermittent flow rate does not represent the maximum service flow rate used for determining the softeners rated capacity and efficien-
cy. Continuous operation at flow rates greater than the maximum service flow rate may affect capacity and efficiency performance. The
validity of these flow rates is verified by NSF.
Efficiency rating is only valid at the minimum stated salt dose and service flow rate. These softeners were efficiency rated according
to NSF/ANSI standard 44.
Capacity to remove clear water iron is substantiated by WQA test data.
Working pressure for Canadian use is 1.4 -- 7.0 kg/cm@.

IMPORTANT: Be sure the
turbine, turbine support
and sensor housing are
firmly in position, in or on
the valve outlet.
H INLET AND OUTLET ADAPTORS --- Push adaptors
into the valve ports. Be sure the o---ring seals a re lu-
bricated with silicone grease or Vaseline.

6. Move the softener into installation position, setting on
a s mooth and level surface. If needed, set it on a
piece of 3/4” thick plywood (slightly larger than the
bottom of the brine tank). Then shim under the ply-
wood to level the softener.
7. Referring to page 5, run inlet and outlet pipes to the
softener, observing all of the following notes.
H If the optional bypass valve is not used, be sure to
use a three valve bypass as typically shown in Figure
1. Position in “bypass” only if needed for softener re-
pairs. The bypass valve maintains continuity of the
water supply w hen the softener is disconnected.
H Be sure to plumb so HARD WATER
flows TO the soft-
ener valve INLET
.
H If sw eat soldering, first disconnect copper pipes from
plastic softener parts. DO NOT SOLDER WITH
COPPER CONNECTED TO THE SOFTENER OR
PLASTIC PARTS WILL BE DAMAGED.
H If using t hreaded fittings, use extreme care not to
cross thread onto plastic.
H Support inlet and outlet plumbing in some manner,
to keep the weight off of the softener valve.
8. CONNECT THE VALVE DRAIN HOSE
Attach a length of 3/8” I.D. hose to the valve drain fit-
ting. Use a hose clamp to hold it in place. Place the
other end of the hose over a floor drain, laundry tub,
sump, standpipe or other suitable drain. BE SURE
TO OBSERVE L OCAL CODES.
drain fitting
hose clamp
IMPORTANT NOTES:
Leave an air gap of about 1---1/2” between the end of the
hose and the drain. This gap is needed so you don’t get
a back ---flow of sewer water into the softener. DO NOT
put the end of the hose into the drain or connect without
the a ir gap.
Place and support the hose so it does not kink or have
sharp bends. Tie or wire the hose in place so water pres-
sure will not make it “whip”. Do not pinch the hose shut.
THE SOFTENER WILL NOT WORK IF THIS DRAIN HOSE
IS PINCHED, PLUGGED OR CLOSED IN ANY WAY.
Keep the hose lower than the drain fitting. In some
homes, to get to a drain you must raise the hose and run
it over head. If you need an overhead drain, do not raise

pass valve (Figure 4). Be sure clips hold parts firmly
in place. Pull on the adaptors or bypass valve to in-
sure they are secure.
Note: If the optional bypass valve is not used, be sure to
install a 3---valve bypass (Figure 5).
2. Run the hard water supply to the valve inlet,and
conditioned water out from the valve outlet.
CAUTION: Do all soldering, and allow to cool, before
connecting pipe to the adaptors or bypass valve.
3. Install the ground clamp if cold water pipe ground
continuity was interrupted.

INSTALLATION (continued) -- (MODEL ESD 2502R39)
4. Run the valve and brine tank overflow drain hoses
(Figure6).Securethevalvedrainhosetothedrainfit-
ting with the included hose clamp. Provide a mini-
mum 1---1/2” air gap at the floor drain, standpipe,
laundry tub, or other approved drain. If you need to
elevate t he valve drain hose to get t o the drain point,
do not raise more than 8’ above the floor. The gravity
overflow hose must be lower than the drain fitting
along the entire run.
Note: Flexible drain hose is not allowed by some state or
local codes. A fitting (1/4” NPT x 1/2” O.D. tube, part no.
0504574) is available from EcoWater for adapting copper
tubing to the valve drain fitting.
5. Route the brine valve tubing out of the brine tank and
connect to the nozzle assembly. Use the small screen
and compression nut included (on skin---pack) to fas -
ten.

7. Open nearby faucets and advance (use RCHG
keypad) the softener valve to backwash position
to vent air from the tank. Turn on the water supply
and allow the softener to fill. When water at nearby
faucets runs smooth, with no more air bubbles, close
the faucets and advance the softener valve to ‘‘ser-
vice’’.
8. Check your installation work for leaks.
9. Make all timer settings, page 9.
10. Sanitize the unit following procedures below, and use
‘‘Recharge Now’’ to start a recharge.
11. Fill the brine tank with salt. You may use most water
conditioner salts, but it must be clean. Recom-
mended nugget, pellet or course solar salts have less
than 1% impurities.
12. Inst all the brine tank cover.
DISINFECTING THE SOFTENER
Care is taken a t the factory to keep your softener 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, installing and operating, bacteria could get into the unit. For this reason, sanitizing as follows is sug-
gested when installing.
1. Use a pail or hose to fill the brine tank with about 3 gallons of water.
2. Remove the brinewell cover and pour about 1---1/2 oz. (2 to 3 tablespoons) of common household bleach
into the softener brinewell. Clorox, Linco, BoPeep, White Sail, E agle, etc. are brand names of bleach readily
available. Replace the brinewell cover.
3. Start an automatic regeneration to draw the bleach into and through the softener, and to the drain.
Note: When the sanitizing regeneration is over all remaining bleach is flushed from the system.

CALIFORNIA EFFICIENCY REQUIREMENT
Your water softener has a High Efficiency feature with an ON or “OFF” setting. This softener setting is shipped
in the “OFF position, which utilizes the maximum rated capacity while most often achieving maximum salt
efficiencies. 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.
IfyouwishtoturntheSaltEfficiencyfeature“ON”(
icon will show in display), follow the instructions on this
page.
11
EXTRA RECHARGE
Sometimes, a manually started regeneration (recharge)
may be desired, or needed. Two examples are:
. You have used more water than usual (guests visiting)
and you may run out of soft water before the next timer
started regeneration.
. You did not refill the softener with salt before it was
gone.
You can start a regeneration right away, or you can set
the timer to regenerate at the next 2:00 AM (or other pre-
set recharge time). Do the following.
RECHARGE NOW
Press the RECHARGE keypad and
hold for 3 seconds. RECHARGE NOW
begins to flash in the display, and the
softener enters the fill cycle of regen-
eration right aw ay. This regeneration will last for about 2
hours. Then, you will have soft water again.
RECHARGE TONIGHT
Press and release (do not hold) the
RECHARGE keypad. RECHARGE TO-
NIGHT flashes in the display, and the
softener begins regeneration at the
next preset recharge time. If you decide to cancel the re-
generation before it has started, press and release the
RECHARGE keypad once more to turn off the flashing
RECHARGE TONIGHT.
PROGRAM MEMORY
If electrical power t o the softener goes off, the time dis-
play is blank but the face plate timer k eeps the correct
time for about 6 hours. When electrical power comes on
again, you have to reset the present time only if the dis-
play is flashing. The HARDNESS and RECHARGE TIME
never require resetting unless a change is desired.
Even if the timer is incorrect after a long power outage,
the softener works as it should to keep your water soft.
However, regenerations may occur at the wrong time of
day until you reset the t imer to the correct time of day.
ERROR CODE
An error code could appear in the face
plate display if a problem occurs in the
softener electronics.
WATER METER:
The water meter, consisting of a t urbine, turbine mount-
ing assembly, and the sensor housing, is located at the
valve outlet port. As water passes through and spins the
turbine, two magnets (in the turbine) cause a back---
and---forth movement of a switch in the sensor housing.
This switch movement sends a pulse to the electronic de-
mand timer.
ELECTRONIC DEMAND TIMER:
The demand timer is actually a small computer. As it re -
ceives pulses from the water meter, it converts them to
gallons of water passing through the water softener. It
multiplies this water usage information times the water
hardness (preprogrammed into timer) to continually cal-
culate the soft water capacity required. The computer ad-
justs daily to w a ter using habits, seeking to supply soft
water for the longest time, using the least (and most effi-
cient) amount of salt and water to regenerate.
When the computer determines more capacity is need-
ed, at the next regeneration starting time (2:00 a.m., or
as otherwise preset), it will schedule a regeneration. RE-
CHARGE TONIGHT shows in the display to inform of the
coming regeneration.
12
REFILLING WITH SAL
T
Remove the brine tank cover and check the salt storage
level frequently. If the unit uses all the salt before you refill
it, you will get hard w ater. Until you have established a
refilling routine, check the salt every 2 or 3 week s. AL-
WAYS refill if less than 1/2 full. Be sure the brinewell cov-
er is on.
RECOMMENDED SALT: Cube, pellet, coarse solar, etc.,
water conditioner salt is recommended. This type of salt
is from high purity evaporated crystals, sometimes
formed, or compressed, into briquets. It has less than 1%
insoluble (will not dissolve in water) impurities. Clean,
high grade rock salts are acceptable, but may require
frequent brine tank cleaning to remove the ‘ ‘sludge’’ resi-
due (insolubles). NOTE: If using potassium chloride
(KCl) instead of standard sodium chloride (NaCl) water
softener salt, hardness setting must be increased by
25%.
SALT NOT RECOMMENDED: Rock salt, high in impuri-
ties,block,granulated,table,icemelting,icecreammak-
ing salts, etc., are not recommended.
SALT WITH IRON REMOVING ADDITIVES: Some salts
have an additive to help a water conditioner handle iron
in a w ater supply. Although this additive may help keep
the resin bed clean, it may also release corrosive fumes
that will weaken and shorten the life of some EcoWater
System Unit parts.
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 dis-
solve in the water t o make brine. Without brine, the resin
bed does not regenerate and you will have hard water.
If the storage tank is full of salt, it is hard to tell if you have
a salt bridge. Salt is loose on top, but the bridge is under
it. Take a broom handle, or like tool, and push it straight
down into the salt. If a hard object is felt, it’s most likely
asaltbridge.Carefully push into the bridge in several
places to break it.
NOTE: Inhumidareas,itisbesttokeepthesaltstorage
level lower, and to refill more often.
CLEANING THE NOZZLE AND VENTURI
A clean nozzle and venturi (Figure 8) is a must for the
EcoWater System Unit to work right. This small unit
creates t he suction to move brine from the brine tank, into
the resin tank. If it should become plugged with sand, silt,
dirt, etc., the EcoWater System Unit will not work, and
you will get hard water.
To get to the nozzle and venturi, remove the EcoWater
System Unit top cover. Be sure the unit is in service
cycle (no water pressure at nozzle and venturi). Then,
holding the nozzle and venturi housing with one hand,
turn off the cap. Do not lose the o ---ring seal. Lift out the
screen support and screen. Then, remove the nozzle and
venturi. Wash the parts in warm, s oapy water and rinse
in fresh water. If needed, use a small brush to remove iron
or dirt. Be careful not to scratch, misshape, etc., surfaces
of the nozzle and venturi. Also, check and clean the gas-
ket and flow plug(s) if dirty.
Carefully replace all parts in the correct order. Lubricate
the o---ring seal with silicone grease and locate in posi-
tion. Install and tighten the cap, by hand only. Do not
overtighten and break the cap or housing.

RESIN BED
CLEANING
If the water supply contains ‘‘clear water ’’ iron (see page
9), regular resin bed cleaning is needed to keep the bed
from coating with iron. Use resin bed cleaner, available
from EcoWater, following directions on the container.
Clean the resin every 6 months, or more often if iron ap-
pears in your conditioned water supply.
ADDING RESIN
Normally, the resin bed (Figure 9) will last the lifetime of
the EcoWater System Unit. However, certain conditions
may require partial or total replacement of the resin bed.
Some of these conditions are:
(1) damaged top and/or bottom distributors have al-
lowed resin to escape
(2)resinbedironfouledbeyonduse
(3) some w ater supplies cause resin degradation

IMPORTANT NOTES:
Turn off t he water s upply and relieve pressure.
Handle the resin tank carefully. It is heavy when filled with
resin and wa ter.
Do not lose o---ring seals or other small parts.
Refer to the assembly instructions and to installation
steps to reassemble and restart the unit.
CHECKING THE MODEL CODE ENTRY (See page 9)
Unplug the transformer at the electrical outlet, then plug it in again. A “beep” w ill sound, then the model code displays
for a few seconds. The test number will then display for a few seconds, followed by the present time display.
CHANGING THE MODEL CODE
IMPORTANT: READ page 9 BEFORE CHANGING THIS CODE.
1. Enter the secondary mode...press SELECT and hold for 3 seconds.
2. Again, press SELECT and hold for 3 seconds. The current model code setting w ill be flashing.
3. Use the ()or() keypad to display the desired model code.
4. Press SELECT to set.
5. Reset the timer (page 9) and reselect other desired options.
