UNPACKING
EcoWater Multi--Purpose Filters are shipped from
the factory in one master carton consisting of ...
...Mineral tank and valve assembly
...Controller cover and timer assembly
...Small parts bags
...Literature kit (includes this manual)
NOTE: Filtering mineral is not included. See
page 21 for ordering information.
Thoroughly check the filter for possible shipping
damage and parts loss. Also inspect and note any
damage to the shipping carton. Notify the trans-
portation company if damage is present. EcoWater
is not responsible for in--transit damages.
Remove and discard (RECYCLE) all packing materi-
als. We suggest that you do not open the small parts
bags until you are ready to use them. Filter assem-
bly instructions are on page 4.
SAFETY GUIDES
Follow the installation instructions carefully. Failure
to install the filter properly voids the warranty.
Before you begin installation, read this entire manu-
al. 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.
NOTE: Codes in the state of Massachusetts require
installation by a licensed plumber. For installation,
use plumbing code 248--CMR of the Commonwealth
of Massachusetts.
Use only lead--free solder and flux for all
sweat-solder connections, as required by state and
federal codes.
Use care when handling the filter. Do not turn upside
down, drop, or set on sharp protrusions.
Do not locate the filter where freezing temperatures
occur. Do not attempt to filter water over 120F.
Freezing, or hot water damage voids the warran-
ty.
Avoid installing in direct sunlight. Excessive sun
heat may cause distortion or other damage to non--
metallic parts.
The filter requires a minimum water flow (see specifi-
cations) at the inlet. Maximum allowable inlet wa-
ter pressure is 125 psi. If daytime pressure is over
80 psi, nighttime pressure may exceed the maxi-
mum. Use a pressure reducing valve if necessary.
Adding a pressure reducing valve may reduce the
flow.
The filter works on 28V 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 over current device such as a 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/EC requires all
electrical and electronic equipment to be dis-
posed 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.

SANITIZING THE FILTER
Care is taken at the factory to keep you water filter
clean and sanitary. Materials used to make the filter
will not infect or contaminate your water supply, and
will not cause bacteria to form or grow. However, dur-
ing shipping, storage, installing and operating,
bacteria could get into the filter. For this reason, sani-
tizing, as follows, is suggested when installing.
Pour about 1 oz. (ETF2100PF10), or 2 oz.
(ETF2100PF12), of the following disinfectant into the
filter.
1. Calcium hypochlorite, available in granular or tablet
form, under trade names such as Perchloron or HTH.
2. Common 5.25% household bleach such as Clorox,
Linco, Bo Peep, White Sail, Eagle, etc.
NOTE -- ACTIVATED CARBON FILTERS: ACTI-
VATED CARBON WILL ABSORB THE SANITIZING
AGENT, EXPENDING SOME CAPACITY.
SANITIZING CONTINUED IN STEP 9, PAGE 9,
AND STEP I ON PAGE 11.
4. Install the top distributor and o--ring seals (4), ex-
actly as shown in Figure 1.
5. Lower the valve assembly, onto the mineral tank,
centering over the standpipe, Push downward, to
squeeze the o--rings, and install the clamp sections
and both retainers. BE SURE THE CLAMPS AND
RETAINERS ARE FIRMLY IN PLACE.

*VALVE DRAIN OPTIONS: Flexible drain hose is
not allowed in all localities (check your codes). For
a rigid valve drain run, plumb according to local
codes. To connect to the valve drain fitting, purchase
an adaptor, garden hose thread x 5/8” (minimum)
tube. Use a hacksaw to cut off barbs from the fitting.
SELECT INSTALLATION LOCATION
Consider all of the following when selecting an
installation location for the filter selected.
STo filter all water in the home, install the filter close
to the water supply inlet. To conserve filtered wa-
ter, outside faucets should remain on raw water.
SIf other water conditioning equipment is installed,
locate as shown in Figure 3.
SA nearby drain is needed to carry away regenera-
tion discharge water. A floor drain is preferred,
with a laundry tub, standpipe, etc., as other op-
tions (check your local codes).
SThe filter works on 28V 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, in a dry location only,
grounded and properly protected by an over cur-
rent device such as a circuit breaker or fuse.
SPosition the filter at least 6” from surrounding
walls, or other appliances, to allow access for
servicing.
SIf installing the filter in an outside location, be sure
to provide protection from the elements, contami-
nation, vandalism, and sunlight heat. The sun’s
heat can melt plastic parts.

1. INSTALL INLET AND OUTLET FITTINGS
NOTE: All fittings are in the small parts bags.
a. Insert the turbine support, into the valve outlet
port, up to the shoulder.
NOTE: If installing the EcoWater bypass valve, see
separate instructions included with it.
b. Slide a lubricated o--ring onto one of the copper
tubes. Carefully insert the copper tube into the outlet
port (Figure 4) and secure in place with a plastic “C”
clip.
NOTE: For lubrication, use silicone grease ap-
proved for use on potable water supplies.
c. Repeat step b on the inlet side.
2. TURN OFF WATER SUPPLY
a. Close the main water supply valve, near well
pump or water meter.
b. Shut off the electricity or fuel supply to the water
heater.
c. Open high and low faucets to drain all water from
hose pipes.
3. INSTALLING 3--VALVE BYPASS
If installing a 3--valve bypass system, plumb as
needed, using Figure 2 on page 5 as a guide. If
installing sweat copper, be sure to USE LEAD--
FREE SOLDER as required by federal and State
codes. Use pipe joint compound on outside pipe
threads.
4. MOVE FILTER INTO PLACE
Move the filter into the installation position, setting
on a solid. smooth and level surface. If needed,
place the filter on a section of 3/4” plywood. Then
shim under the plywood to level the filter Figure 5.
CAUTION: DO NOT PLACE SHIMS DIRECTLY UN-
DER THE SHROUD. The weight of the tank may
cause the shroud to fracture at the shim.
5. ASSEMBLE INLET AND OUTLET PLUMBING
Measure, cut and loosely assemble pipe and fittings
from the main water pipe (or from bypass valves
installed in step 3), to the filter inlet and outlet copper
tubes.
BE SURE UNFILTERED WATER SUPPLY PIPE
GOES TO THE FILTER INLET SIDE. Trace the wa-
ter flow direction to be sure.

6. COLD 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 if installation, shown in Figure
2, will maintain ground continuity. If you use the plas-
tic bypass valve at the filter, continuity is broken. To
restore the ground, install one of the following
grounds.
a. Use the EcoWater ground clamp kit (not included)
to make a jumper across the inlet and outlet pipes
Figure 6a.
b. Install a #4 copper wire across the removed sec-
tion of main water pipe, securely clamping on both
ends (Figure 6b) -- parts not included.
7. CONNECT INLET & OUTLET PLUMBING
Complete the inlet and outlet plumbing as applica-
ble.
a. SOLDERED COPPER
(1) Thoroughly clean and flux all joints.
(2) Remove the inlet and outlet tubes from the valve
(pull plastic “C” clips), and o--rings from the tubes.
DO NOT SOLDER WITH TUBES IN THE VALVE.
SOLDERING HEAT WILL DAMAGE THE VALVE.
(3) Make all solder connections. Be sure to keep fit-
tings fully together, and pipes square and straight.
(4) AFTER PLUMBING HAS COOLED, repeat
steps 1b and 1c.
b. THREADED PIPE
(1) Apply pipe joint compound to all outside pipe
threads.
(2) Tighten all threaded joints.
(3) If SOLDERING TO INLET AND OUTLET
TUBES, observe steps (1) through (4) above.
c. CPVC PLASTIC PIPE
(1) Clean, prime and cement all joints (follow instruc-
tions of the plastic pipe and fittings manufacturer).
(2) IF SOLDERING TO INLET AND OUTLET
TUBES, observe preceding steps (1) through (4).
8. INSTALL VALVE DRAIN HOSE
a. Connect a length of 5/8” I.D. (minimum) hose to
the valve drain elbow on the controller Figure 2. The
elbow accepts either a hose onto the barb fitting, or
standard garden hose onto the threads. To use the
threads, cut off the barbs with a hacksaw.
NOTE: Flexible drain hose is not allowed in all locali-
ties. See option on page 7.
b. Run the hose to a floor drain, and as typically
shown in Figure 2, tie or wire the end to a brick or oth-
er heavy object. This will prevent “whipping” during
regenerations. Be sure to provide a 1--1/2” minimum
air gap, to prevent possible sewer water backup.

this hose. Avoid long drain hose runs, or elevating
the hose.
9. PRESSURE TESTING FOR LEAKS
TO PREVENT EXCESSIVE AIR PRESSURE IN
THE FILTER AND PLUMBING SYSTEM, DO THE
FOLLOWING STEPS IN ORDER
a. Open two or more filtered water faucets, both hot
and cold.
b. Referring to Figure 7, turn the bypass valves to
service position.
c. Slowly open the main water supply valve.
d. Close the filtered water faucets after both of the
following occur.
-- water runs smoothly, with no air bubbles
-- you can smell the sanitizing (page 4) bleach odor
at the faucets
e. Check your complete installation for leaks. If re-
work is required, be sure to observe precautions in
step 6.
10. CONNECT ALL LEADWIRES
a. Connect the wire harness to the valve switch Fig-
ure 8. The switch is on the valve, by the large gear.
NOTE: Check to be sure the connector is secure, on
the back of the timer.
b. Attach the male connector, on the valve motor
leadwire, the the matching female connector on the
faceplate timer.
c. Connect the power cable leads to the back of the
timer.
11. CONNECT TO ELECTRICAL POWER
Plug the power supply into a continuously “live”,
grounded, 120V, 60Hz household electrical outlet,
approved by local codes.

I. Press and hold the RECHARGE keypad for three
seconds until RECHARGE NOW begins to flash in
the display, starting a recharge. This recharge
flushes “fines” from the new mineral, and purges air
and bleach remaining from the sanitizing procedure.
The filter returns to service in about 30 minutes.
After the recharge has completed, fully open a cold
water faucet downstream from the filter and allow 50
gallons of water to pass through the filter. This
should take 20 minutes. Close the faucet.
II. 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 unfiltered water
and as hot water is used, it refills with filtered water.
In a few days, hot water will be fully filtered. To have
fully filtered water immediately, wait until the re-
charge (step I above) is over. Then, drain the water
heater until water runs cold.
III. THE TIMER IS NOW PROGRAMMED AND
INSTALLATION IS COMPLETE.
FEATURES / OPTIONS
RECHARGE NOW -- For an immediate extra back-
wash at any time, use this feature. Press and hold
in the RECHARGE keypad for three seconds until
RECHARGE NOW begins to flash in the display. The

The default settings for fill (0 minutes), brine draw (0
minutes), backwash (25 minutes) and fast rinse (5
minutes) cycles of regeneration are factory set for
maximum performance of the filter. Use the following
procedures to check for correct cycle times, or to
change if desired. However, only trained technicians
should change the time settings.
ADJUSTABLE FILL -- Press and hold the SELECT
button until the display shows “000----”, then press
the SELECT button once to advance to the Fill time
adjust screen.
Using the UP or DOWN buttons, adjust the fill time
from 0 minutes to 99:59 minutes.
ADJUSTABLE BRINE DRAW -- Press and hold the

then press the SELECT button twice to advance to
the Brine Draw time adjust screen.
Using the UP or DOWN buttons, adjust the brine
draw time from 0 minutes to 255 minutes.
12 OR 24 HOUR CLOCK -- The electronic controller
has been factory preset to display a 12 hour clock
(AM / PM). If you prefer, you may change this to
display a 24 hour clock. Press and hold the SELECT
button until the display shows “000----”, then press
the SELECT button three times to advance to the
“12 hr” or “24 hr” time format screen.
Using the UP or DOWN buttons, set the time format
to 12 or 24 hours.
ADJUSTABLE BACKWASH -- Press and hold the
SELECT button until the display shows “000----”,
then press the SELECT button four times to ad-
vance to the Backwash time adjust screen.
Using the UP or DOWN buttons, adjust the back-
wash time from 0 minutes to 99 minutes.
ADJUSTABLE FAST RINSE -- Press and hold the
SELECT button until the display shows “000----”,
then press the SELECT button five times to advance
to the Fast Rinse time adjust screen.
Using the UP or DOWN buttons, adjust the fast rinse
time from 0 minutes to 99 minutes.
TIMER “POWER--OUTAGE MEMORY” -- If electri-
cal power to the timer is interrupted, the “memory”
built into timer circuitry keeps time settings for 6
hours (minimum) or more. The display is blank and
the filter will not regenerate. When electrical power
comes on, one of two things will happen.
1. The present time of day will show steady, meaning
the timer memory has kept all settings.
2. The display will show a time, but it will be flashing.
The timer memory did not keep the time setting and
it must be reset (page 10). If you do not reset the time
setting, regenerations will most likely be at the wrong
time of day.
NOTE: The flashing display is to remind you to reset
the timer.
NOTE: If the filter was in a backwash when power
was lost, it will now finish the cycle.

GENERAL INFORMATION
...SEDIMENT FILTERS -- A sediment filter removes,
sand, clay, silt, or fine organic matter from water.
You can see sediment in water by holding a sample,
in a clear glass, up to a light. The particles are either
suspended or settled to the bottom of the glass.
“Filter Aggregate” mineral mechanically filters the
sediment particles as water passes through the bed.
This mineral lasts indefinitely when properly main-
tained.
...ACID NEUTRALIZERS -- Acid water (6.0 to 6.8
pH) is corrected with an acid neutralizer filter. Acid
water, although sometimes clear in appearance,
shortens the life of iron pipe, and corrodes copper or
brass pipe and fittings. It causes green or blue
stains on plumbing fixtures and may etch porcelain
enamel over a period of time.
Acid water, as it passes through the filter Neutralite
mineral bed, dissolves some of the mineral. This
raises the pH above 6.8, to neutralize the acid. Be-
cause the mineral does dissolve, the filter eventually
needs refilling. The time between refills varies with
the degree of acidity and how much water is used.
The average life of the bed is about one year.
...TASTE AND ODOR FILTERS -- A taste and odor
filter removes most tastes, odors and certain organic
colors from water. Bad tastes and odors are due to
a variety of causes (chlorine, petroleum, tannins,
etc.). The activated carbon mineral of a taste and
odor filter has a high capacity for absorbing these im-
purities.
The activated carbon bed usually lasts for about one
year. However, high amounts of tastes and odors
and/or excessive water usage may shorten this time.
Activated carbon is nonregenerative and needs re-
placing when exhausted.

SERVICE, BACKWASH AND FAST RINSE
SERVICE (Figure 10):Unfiltered water enters the
valve inlet port. Internal valve porting routes the wa-
ter down and out the top distributor, into the mineral
tank. The water is filtered as it passes through the
mineral bed, then enters the bottom distributor. Fil-
tered water flows back into the valve and out the
valve outlet, to the house filtered water pipes.
In time, the filter needs cleaning to remove sedi-
ments, dirt, iron, etc., from the mineral bed. This
cleaning is done in two stages, or cycles, called
backwash and fast rinse. It is started automatically
by the timer.
BACKWASH (Figure 11): The timer starts the valve
motor and moves the valve into backwash position.
Water is routed down and out the bottom distributor,
up through the mineral bed, and out the top distribu-
tor to the drain. The fast flow (controlled by a flow
plug in the drain fitting) flushes dirt, sediments, iron
deposits, etc. to the drain. The mineral bed is lifted
and expanded for maximum cleaning.
FAST RINSE (Figure 12):Valve rotation positions
the inner discs so water flow enters the mineral tank
through the top, and exits at the bottom, to the drain.
The fast flow of water downward, packs the mineral
bed and prepares it for return to service.
The timer energizes the valve motor again to return
the valve to service.

NEUTRALIZING FILTER -- CHECKING THE MIN-
ERAL LEVEL IN THE TANK: As explained on page
14, the mineral dissolves in the water to neutralize
the acid. How fast is dissolves depends on how
much water you household uses and the pH of the
water.
Every few months you should measure the mineral
bed level in the tank. Always add new mineral before
the tank is empty. To measure, do the following.
1. Refer to page 11 and initiate the RECHARGE
NOW feature.
2. When water starts to run from the drain hose, put
the plumbing bypass valve(s) in bypass position,
see Figure 7, page 8, TO DEPRESSURIZE THE
FILTER.
3. Unplug the power supply at the wall outlet.
4. Remove the controller cover.
5. Disconnect the inlet and outlet copper tubes, see
page 7.
6. Remove the valve assembly from the mineral
tank, page 4.
7. Remove the top distributor and four o--ring seals,
page 4.
FIGURE 13
SUGGESTED FREEBOARD

8. Use a yard stick or steel tape measure to find the
distance down to the top of the mineral bed, see Fig-
ure 13. If 15” below the suggested freeboard, add
more neutralite material.
9. Use a funnel to add more mineral, if needed.
10. Flush all mineral from the tank top opening.
Then replace the distributor and four o--ring seals,
Figure 1, page 4.
11. Do the following steps to return the filter to ser-
vice.
-- step 4, page 4
-- step 1b and 1c, page 7
-- step 8, page 8, if hose was disconnected
-- steps 9 through 12, page 9.
NOTE: After electrical power is applied, see page 12
if the time display is flashing.
-- initiate RECHARGE NOW feature, see page 11.
TASTE AND ODOR FILTER -- REPLACING THE
ACTIVATED CARBON MINERAL BED (SEE PAGE
14): When the filter no longer removes tastes and/or
odors from the water, the activated carbon bed must
be replaced. To replace the bed:
1. Do steps 1 through 7, above left.
2. Carefully lay the filter tank over. Pull the standpipe
and bottom distributor from the mineral bed.
3. Dump the contents of the tank into a suitable con-
tainer.
4. Stand the tank upright and replace the bottom dis-
tributor and standpipe.
5. Add the required amounts of gravel, filter sand,
and activated carbon mineral. See specifications,
page 3.
6. Do steps 10 and 11, above.

TROUBLESHOOTING
ALWAYS MAKE THESE INITIAL CHECKS FIRST
1. Does the time display show the correct time of
day?
...If display is blank, check power source to the filter.
...If time is flashing, power was off for over two days.
The filter resumes normal operation but back-
washes occur at the wrong time.
2. Plumbing bypass valve(s) must be in SERVICE
position (see figure 7, page 9).
3. The inlet and outlet pipes must connect to the filter
inlet and outlet respectively.
4. Is the power supply plugged into a “live” grounded
wall outlet, and the power cable fastened securely?
5. The valve drain hose must be free of kinks and
sharp bends.
If you do not find the problem after making the initial
checks, do the MANUAL ADVANCE DIAGNOS-
TICS.
