SAFETY GUIDES
Follow the installation instructions carefully. Failure to install the EcoWater 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. 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.
Avoid 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 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.)
The EcoWater softener works on 24 volt -- 60 hz electrical power only. Be sure to use the included transformer 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 according 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.

near the water meter or pressure tank, to turn off the
water.
2. Shut off the gas or electric supply to the water heater.
3. Open the highest and lowest water faucets in your
house to let water drain from the pipes. Close faucets
after water has drained.
4. If not already done, remove all cardboard or plastic
packing pieces from inside the softener.
5
INSTALLATION (continued) -- (MODELS ESD 518 & ESD 2502R30)
5. INSTALL INLET AND OUTLET ADAPTORS, OR
THE OPTIONAL BYPASS VALVE.
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 repairs. The bypass valve maintains continuity of the
water supply when the softener is disconnected.
H
Be sure to plumb so HARD WATER flows TO the softener valve INLET.
H
If sweat soldering, first disconnect copper pipes from
plastic softener parts. DO NOT SOLDER WITH
COPPER CONNECTED TO THE SOFTENER OR
PLASTIC PARTS WILL BE DAMAGED.
BYPASS VALVE --- Push the bypass valve into the
valve ports (can be inverted for connecting to floor
level plumbing). Be sure the o---ring seals are lubricated with silicone grease or Vaseline.
H
If using threaded 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.
SNAP THE TWO LARGE HOLDING CLIPS INTO
PLACE, FROM THE TOP DOWN AS SHOWN. BE
SURE THEY SNAP FIRMLY INTO PLACE, SO THE
ADAPTORS, OR BYPASS VALVE, DO NOT PULL
OUT.
8. CONNECT THE VALVE DRAIN HOSE
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 are lubricated with silicone grease or Vaseline.
-- OR--
H
Attach a length of 3/8” I.D. hose to the valve drain fitting. 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 LOCAL CODES.
FIGURE 2
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 air gap.
Place and support the hose so it does not kink or have
sharp bends. Tie or wire the hose in place so water pressure 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.
6. Move the softener into installation position, setting on
a smooth 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 plywood to level the softener.
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
the hose more than 8’ above the floor.

DISINFECTING THE SOFTENER
Care is taken at 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 suggested 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, Eagle, 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.

NOTE: If your water supply contains iron, compensate
for it by adding to the water hardness number. For example, assume your water is 15 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 25 for your hardness number.
SOUND “BEEPER”: A “beeper” sounds while pressing
keypads for timer set-up. One beep signals a change in
the face plate display. Repeated beeps means the timer
will not accept a change from the keypad you have
pressed, telling you to use another keypad. For example,
in setting the hardness (step 2), the beeper sounds repeatedly when the display reaches 1 using the DOWN
keypad, or the highest hardness setting using the UP
keypad.

either on or off.
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.
If you wish to turn the Salt Efficiency feature “ON” (
page.
icon will show in display), follow the instructions on this
10
EXTRA RECHARGE
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 timer to the correct time of day.
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.
ERROR CODE
. You did not refill the softener with salt before it was
gone.
An error code could appear in the face
plate display if a problem occurs in the
softener electronics.
You can start a regeneration right away, or you can set
the timer to regenerate at the next 2:00 AM (or other preset recharge time). Do the following.
WATER METER:
RECHARGE NOW
The water meter, consisting of a turbine, turbine mounting 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 demand timer.
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 regeneration right away. This regeneration will last for about 2
hours. Then, you will have soft water again.
RECHARGE TONIGHT
ELECTRONIC DEMAND TIMER:
Press and release (do not hold) the
RECHARGE keypad. RECHARGE TONIGHT flashes in the display, and the
softener begins regeneration at the
next preset recharge time. If you decide to cancel the regeneration before it has started, press and release the
RECHARGE keypad once more to turn off the flashing
RECHARGE TONIGHT.
The demand timer is actually a small computer. As it receives 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 calculate the soft water capacity required. The computer adjusts daily to water using habits, seeking to supply soft
water for the longest time, using the least (and most efficient) amount of salt and water to regenerate.
When the computer determines more capacity is needed, at the next regeneration starting time (2:00 a.m., or
as otherwise preset), it will schedule a regeneration. RECHARGE TONIGHT shows in the display to inform of the
coming regeneration.
PROGRAM MEMORY
If electrical power to the softener goes off, the time display is blank but the face plate timer keeps the correct
time for about 6 hours. When electrical power comes on
again, you have to reset the present time only if the dis-

REFILLING WITH SALT
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 the 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, soapy 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 gasket 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 position. Install and tighten the cap, by hand only. Do not
overtighten and break the cap or housing.
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 water. Until you have established a
refilling routine, check the salt every 2 or 3 weeks. ALWAYS refill if less than 1/2 full. Be sure the brinewell cover 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’’ residue (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 impurities, block, granulated, table, ice melting, ice cream making salts, etc., are not recommended.
FIGURE 8
SALT WITH IRON REMOVING ADDITIVES: Some salts
have an additive to help a water conditioner handle iron
in a water 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 dissolve in the water to 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
a salt bridge. Carefully push into the bridge in several
places to break it.
NOTE: In humid areas, it is best to keep the salt storage
level lower, and to refill more often.

RESIN BED CLEANING
FIGURE 9
plug distributor tube
while adding resin
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 appears in your conditioned water supply.

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:
IMPORTANT NOTES:
Turn off the water supply and relieve pressure.
(1) damaged top and/or bottom distributors have allowed resin to escape
(2) resin bed iron fouled beyond use
(3) some water supplies cause resin degradation
Handle the resin tank carefully. It is heavy when filled with
resin and water.
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.
To add more resin, or to replace the entire bed, use the
following guides. See resin requirements on page 4.
CHECKING THE MODEL CODE ENTRY (See page 9)
Unplug the transformer at the electrical outlet, then plug it in again. A “beep” will 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 will 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.
