SAFETY GUIDES
Follow the in tallation in truction carefully. Failure to in tall the EcoWater oftener properly voids
the warranty.
Before you begin in tallation, read thi entire manual. Then, obtain all the material and tool you will
need to make the in tallation.
Check local plumbing and electrical codes. The in tallation mu t conform to them.
Use only lead--free solder and flux for all weat-- older connection , a required by tate and feder-
al code .
U e care when handling the EcoWater oftener. Do not turn up ide down, drop, or et on harp pro-
tru ion .
Do not locate the EcoWater oftener where freezing temperature occur. Do not attempt to treat water
over 120°F. Freezing, or hot water damage voids the warranty.
Avoid in talling in direct unlight. Exce ive un heat may cau e di tortion or other damage to non--
metallic part .
The EcoWater oftener require a minimum water flow of 3 gallon per minute at the inlet. Maximum
allowable inlet water pressure is 125 psi. If daytime pre ure i over 80 p i, nighttime pre ure
may exceed the maximum. U e a pre ure reducing valve if nece ary. (Adding a pre ure reducing
valve may reduce the flow.)
The EcoWater softener works on 24 volt--60 hz electrical power only. Be ure to u e the included
tran former and plug it into a nominal 120V, 60 cycle hou ehold outlet that i grounded and properly
protected by an over current device uch a a circuit breaker or fu e. If tran former i replaced, u e
only the authorized ervice, Cla II, 24 volt, 10 VA tran former.
Thi y tem i not intended to be u ed for treating water that i microbiologically un afe or of unknown
quality without adequate di infection before or after the y tem.
European Directive 2002/96/EC require all electrical and electronic equipment to be di po ed
of according to Wa te Electrical and Electronic Equipment (WEEE) requirement . Thi directive
or imilar law are in place nationally and can vary from region to region. Plea e refer to your
tate and local law for proper di po al of thi equipment.

WATER
Man’ very exi tence depend on water. It i 1 of the
ba ic commoditie of life. Water i be t a nature
provide it, i a common mi conception. Practically
all natural water need refinement or treatment to
make it afe to drink or more ati factory to u e.
The earth’ water upply cycle tart in the upper
cloud layer . A it fall to the earth a rain or now,
it pick up impuritie and ga e from the atmo-
phere. Landing on earth, it eep over and through
the ground, di olving earth mineral . Pa ing
through lime tone, it di olve calcium and magne-
ium, the hardne mineral . Iron depo it impart
iron to the water. Acidity and ediment are other
water condition .
Municipal water upplie come from urface re er-
voir , uch a lake and river , or from underground
re ervoir . U ually, municipalitie chlorinate the wa-
ter to make it afe to drink. Sediment i removed by
filtration. Ta te and odor are reduced or elimi-
nated. The water i conditioned to comply with cer-
tain pecification . However, hardne mineral ,
ta te and odor are not alway reduced to the mo t
de irable level .
Underground re ervoir provide our private water
upplie . Becau e the water i raw and untreated, it
can have varying amount of hardne , iron, ta te ,
odor , acidity, or combination of the e. Different lo-
calitie and water level affect mineral content.
WATER CONDITIONING
Water conditioning i the treatment of four general
condition . The e are: (1) Hardness, (2) Iron, (3)
Acidity, (4) Sediments.
(1) HARDNESS i a term to de cribe the pre ence
of calcium and magne ium mineral in water. A
chemical analy i accurately mea ure the amount
of mineral in grain weight. For example, 1 gallon of
water with 5 grain per gallon (gpg) hardne ha
di olved mineral , that if olidified, about equal
the ize of 1 ordinary a pirin tablet. One gallon of wa-
ter, 25 gpg hard, ha a mineral content equal in ize
to 5 a pirin tablet . Water hardne varie greatly
acro the country. It generally contain from 3 to
100 gpg.
Hard water affect living in general. Hardne miner-
al combine with oap to make a oap curd. The
curd greatly reduce the cleaning action of oap.
Precipitated hardne mineral form a cru t on
cooking uten il , appliance , and plumbing fixture .
Even the ta te of food are affected. A water oft-
ener remove the hardne mineral to eliminate
the e problem , and other . Page 16--17 de cribe
how the EcoWater conditioner work .
Sodium Information: Water oftener u ing odium
chloride ( alt) for regeneration add odium to the
water. Per on on odium re tricted diet hould
con ider the added odium a part of their overall in-
take.
(2) IRON in water i mea ured in part per million
(ppm). The total* ppm of iron, and type or type *, i
determined by chemical analy i . Four different
type of iron in water are: ❶Ferrou (clear water),
❷Ferric (red water), ❸Bacterial and organically
bound iron, ❹Colloidal and inorganically bound iron
(ferrou or ferric).
*Water may contain one or more of the four type of
iron and any combination of the e. Total iron i the
um of the content .
❶Ferrou (clear water) iron i oluble and di olve
in water. It i u ually detected by taking a ample of
water in a clear bottle or gla . Immediately after tak-
ing, the ample i clear. A the water ample tand ,
it gradually cloud and turn lightly yellow or brown
a air oxidize the iron. Thi u ually occur in 15 to
30 minute . An EcoWater conditioner will remove
moderate amount of thi type of iron*.
*Capacity to remove clear water iron wa te ted in
the field by the manufacturer.
❷Ferric (red water), and ❸Bacterial and organically
bound iron are in oluble. Thi iron i vi ible immedi-
ately when drawn from a faucet becau e it ha oxi-
dized before reaching the home. It appear a mall
cloudy yellow, orange, or reddi h u pended par-
ticle . After the water tand for a period of time, the
particle ettle to the bottom of the container. Gener-
ally the e iron are removed from water by filtration.
Chlorination i al o recommended for bacterial iron.
An EcoWater conditioner will remove minimal quan-
titie ( ee pecification ) of ferric iron.

❹Colloidal and inorganically bound iron i a ferric or
ferrou form that will not filter or exchange out of wa-
ter. In ome in tance , treatment may improve col-
loidal iron water, but alway consult a qualified wa-
ter chemistry lab before attempting to treat it.
Colloidal iron water u ually ha a yellow appearance
when drawn. After tanding for everal hour , the
color per i t and the iron doe not ettle, but re-
main u pended in the water.
Iron in water cau e tain on clothing and plumbing
fixture . It negatively affect the ta te of food, drink-
ing water, and other beverage .
(3) ACIDITY or acid water i cau ed by carbon diox-
ide, hydrogen ulfide, and ometime indu trial
wa te . It i corro ive to plumbing, plumbing fix-
ture , water heater , and other water u ing ap-
pliance . In can al o damage and cau e premature
failure of eal , diaphragm , etc., in water handling
equipment.
A chemical analy i i needed to mea ure the de-
gree of acidity in water. Thi i called the pH of water.
Water te ting below 6.9 pH i acidic. The lower the
pH reading, the greater the acidity. A neutralizer filter
or a chemical feed pump are u ually recommended
to treat acid water.
(4) SEDIMENT i fine, foreign material particle u -
pended in water. Thi material i mo t often clay or
ilt. Extreme amount of ediment may give the wa-
ter a cloudy appearance. A ediment filter normally
correct thi condition.
COMPLETE WATER CONDITIONING SYSTEM -- Seldom would all the water conditioner hown below be
needed on one water upply. The drawing doe how the proper equence location of each conditioner. Note
that only a ta te and odor filter i in talled after a water oftener. All other filter belong before the water often-
er. Al o note that out ide faucet line are before the treated water, and the water heater i after all condition-
ing.

in tallation location for the EcoWater conditioner.
To condition all water in the home, in tall the Eco-
Water conditioner clo e to the water upply inlet,
and before all other plumbing connection , ex-
cept out ide water pipe . Out ide faucet hould
remain on hard water to avoid wa ting condi-
tioned water and alt ( ee drawing on page 6).
A nearby drain i needed to carry away regenera-
tion di charge water. A floor drain i preferred,
with a laundry tub, tandpipe, etc., a other op-
tion (check your local code ).
The EcoWater conditioner works on 24 volts
only. A tran former i included to reduce
120V--60 Hz hou e power. Provide an approved,
grounded outlet within 10’ of the conditioner. The
tran former ha an attached 10’ power cable for
connection between the outlet and the timer.
Po ition the EcoWater conditioner at lea t 6” from
urrounding wall , or other appliance , to allow
acce for adding alt and ervicing.
Locate the EcoWater conditioner, in the plumbing
y tem, after all other in talled water condition-
ing equipment, except for a ta te and odor filter.
A ta te and odor filter i in talled after all equip-
ment. Always install the EcoWater conditioner
BEFORE the water heater. See the Safety
Guide on page 3. To reduce the ri k of hot water
back-up, conditioned water piping between the
EcoWater conditioner and water heater hould
be a long a po ible.

EXTRA RECHARGE
Sometime , a manually tarted regeneration (re-
charge) may be de ired, or needed. Two example
are:
---- You have u ed more water than u ual (gue t
vi iting) and you may run out of oft water before the
next timer tarted regeneration.
---- You did not refill the oftener with alt before it
wa gone.
You can tart a regeneration right away, or you can
et the timer to regenerate at the next 2:00 AM (or
other pre et recharge time). Do the following.
RECHARGE NOW
Pre the RECHARGE keypad and hold for 3 se-
conds. RECHARGE NOW begin to fla h in the di -
play, and the oftener enter the fill cycle of regen-
eration right away. Thi regeneration will la t for
about 2 hour . Then, you will have oft water again.
RECHARGE TONIGHT
Pre and relea e (do not hold) the RECHARGE
keypad. RECHARGE TONIGHT fla he in the di -
play, and the oftener begin regeneration at the
next pre et recharge time. If you decide to cancel
the regeneration before it ha tarted, pre and re-
lea e the RECHARGE keypad once more to turn off
the fla hing RECHARGE TONIGHT.
PROGRAM MEMORY
If electrical power to the oftener goe off, the time
di play i blank but the face plate timer keep the
correct time for about 6 hour . When electrical pow-
er come on again, you have to re et the pre ent
time only if the di play i fla hing. The HARDNESS
and RECHARGE TIME never require re etting un-
le a change i de ired.
Even if the timer i incorrect after a long power out-
age, the oftener work a it hould to keep your wa-
ter oft. However, regeneration may occur at the
wrong time of day until you re et the timer to the cor-
rect time of day.
ERROR CODE
An error code could appear in the face plate di play
if a problem occur in the oftener electronic . If you
ee an error code in tead of the time of day, ee

ELECTRONIC DEMAND TIMER:
The demand timer i actually a mall computer. A

Service Information
REFILLING WITH SALT
Remove the brine tank cover and check the alt tor-
age level frequently. If the unit u e all the alt before
you refill it, you will get hard water. Until you have
e tabli hed a refilling routine, check the alt every 2
or 3 week . ALWAYS refill if le than 1/2 full. Be
sure the brinewell cover is on.
RECOMMENDED SALT: Cube, pellet, coar e olar,
etc., water conditioner alt i recommended. Thi
type of alt i from high purity evaporated cry tal ,
ometime formed, or compre ed, into briquet . It
ha le than 1% in oluble (will not di olve in water)
impuritie . Clean, high grade rock alt are accept-
able, but may require frequent brine tank cleaning to
remove the ‘‘ ludge’’ re idue (in oluble ). NOTE: If
u ing pota ium chloride (KCl) in tead of tandard
odium chloride (NaCl) water oftener alt, hard-
ne etting mu t be increa ed by 25%.
SALT NOT RECOMMENDED: Rock alt, high in im-
puritie , block, granulated, table, ice melting, ice
cream making alt , etc., are not recommended.
SALT WITH IRON REMOVING ADDITIVES: Some
alt have an additive to help a water conditioner
handle iron in a water upply. Although thi additive
may help keep the re in bed clean, it may al o re-
lea e corro ive fume that will weaken and horten
the life of ome EcoWater Sy tem Unit part .
BREA ING A SALT BRIDGE
Sometime , a hard cru t or alt bridge form in the
brine tank. It i u ually cau ed by high humidity or
the wrong kind of alt. When the alt bridge , an
empty pace form between the water and the alt.
Then, alt will not di olve in the water to make
brine. Without brine, the re in bed doe not regener-
ate and you will have hard water.
If the torage tank i full of alt, it i hard to tell if you
have a alt bridge. Salt i loo e on top, but the bridge
i under it. Take a broom handle, or like tool, and
pu h it traight down into the alt. If a hard object i
felt, it’ mo t likely a alt bridge. Carefully pu h into
the bridge in everal place to break it.
NOTE: In humid areas, it is best to keep the salt stor-
age level lower, and to refill more often.
CLEANING THE NOZZLE AND VENTURI
A clean nozzle and venturi (FIG. 13) i a mu t for the
EcoWater Sy tem Unit to work right. Thi mall unit
create the uction to move brine from the brine
