SAFETY GUIDES
Follow the installation instructions carefully. Failure to
install the EcoWater Systems Central Water Filtration
System 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-solder
connections, as required by state and federal codes.
Use care when handling the EcoWater Systems Central
Water Filter. Do not turn upside down, drop, or set on
sharp protrusions.
Do not locate the EcoWater Systems Central Water Filter
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 Systems Central Water Filter requires a
minimum water pressure of 30 psi 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 neces-
sary (Adding a pressure reducing valve may reduce the
flow).
The EcoWater Systems Central Water Filter works on
24 volt, 60 Hz electrical power only. Be sure to use the
included transformer 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. If transformer is
replaced, use only the authorized service, Class II, 24V,
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 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 the equipment.

Do not operate the Central Water Filtration System
where freezing temperatures occur. Do not
attempt to treat water over 120ºF. Freezing tem-
peratures or hot water damage voids the warranty.
To condition all water in the home, install the
Central Water Filtration System close to the water
supply inlet, and before all other plumbing connec-
tions, except outside water pipes.
A nearby drain is needed to carry away Clean
Rinse discharge water. Use a floor drain, laundry
tub, sump, standpipe, or other options (check your
local codes). See "Air Gap Requirements" and
"Valve Drain Requirements" sections. If a drain is
not available, it is still possible to operate the
Central Water Filtration System in a manual Clean
Rinse mode. See “Operating in Manual Clean
Rinse Mode.” The automatic Clean Rinse must be
disabled if the Central Water Filtration System will
not be connected to a drain (See Page 15).
The Central Water Filtration System works on
24 volt, 60 Hz electrical power only, supplied by a
direct plug-in transformer (included). Provide an
electrical outlet in accordance with NEC and local
codes.
Do not install the Central Water Filtration System
on a hot water line (See Figure 2 below).

SYSTEMS Installation Requirements
PLUMBING CODES
All plumbing must be completed in accordance with
national, state and local plumbing codes.
VALVE DRAIN REQUIREMENTS
Using the flexible drain hose (included), measure and
cut to the length needed. Flexible drain hose is not
allowed in all localities (check your plumbing codes).
If local codes do not allow use of a flexible drain
hose, a rigid valve drain run must be used. Purchase
a compression fitting (1/2 NPT x 1/2 in. minimum
tube) and 1/2" tubing from your local hardware store.
Plumb a rigid drain as needed (see Figure 3, below).
NOTE: Avoid drain hose runs longer that 30 feet.
Make the valve drain line as short and direct
as possible.
It is recommended that the Central Water Filtration
System be installed near a drain. However, if a drain
is not available, it is still possible to operate the
Central Water Filtration System in a manual Clean
Rinse mode. See “Operating in Manual Clean Rinse
Mode” section. The automatic Clean Rinse function
must be disabled if the Central Water Filtration
System will not be connected to a drain.
TYPICAL INSTALLATION
In the state of Massachusetts: The Commonwealth
of Massachusetts plumbing code 248-CMR shall
be adhered to. A licensed plumber shall be used
for this installation.
AIR GAP REQUIREMENTS
A drain is needed for Clean Rinse discharge water. A
floor drain, close to the Central Water Filtration
System, is preferred. A laundry tub, standpipe, etc.
are other drain options. Secure valve drain hose in
place. Leave an air gap of 1-1/2” between the end of
the hose and the drain. This gap is needed to pre-
vent backflow of sewer water into the Central Water
Filtration System . Do not put the end of the drain
hose into the drain.

5. ASSEMBLE INLET & OUTLET PLUMBING
Measure, cut, and loosely assemble pipe and fittings
from the main water pipe (or from the bypass valves
installed in Step 4), to the inlet and outlet copper
tubes, installed in Step 2b.
Be sure incoming water supply pipe goes to the
valve inlet side. Trace the water flow direction to be
sure.
6. CONNECT INLET & OUTLET PLUMBING
a. SOLDERED COPPER
(1) Thoroughly clean and flux all joints.
(2) Pull the plastic “C'' clips and remove the inlet and
outlet tubes from the valve. Remove o-rings from the
tubes. DO NOT solder with tubes in the valve.
Soldering heat will damage the valve.
NOTE: If installing a ground as shown in Figure 9,
place ground clamps on copper tubes before solder-
ing (See Step 6a).
(3) Make all solder connections. Be sure to keep fit-
tings fully together, and pipes square and straight.
b. THREADED PIPE
(1) Apply pipe joint compound to all outside pipe
threads.
(2) Tighten all threaded joints.
(3) If soldering to the inlet and outlet tubes, observe
Step 6a above.
c. CPVC PLASTIC PIPE
(1) Clean, prime and cement all joints, following the
manufacturer's instructions supplied with the plastic
pipe and fittings.
(2) If soldering to the inlet and outlet tubes, observe
Step 6a above.

7. 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 of installation, shown in Figure 7,
will maintain ground continuity. If you use the plastic
bypass, continuity is broken. To restore the ground,
do either step 7a or 7b following.
a. Use the ground clamp kit (included) to make a
jumper across the inlet and outlet copper tubes (See
Figure 9).
b. Install a #4 copper wire across the removed sec-
tion of main water pipe, securely clamping at both
ends (See Figure 10) – parts not included.
8. INSTALL VALVE DRAIN HOSE
NOTE: See valve drain options on Page 5.
a. Connect a length of 1/2" I.D. hose (check codes) to
the valve drain elbow, on the controller. Use a hose
clamp to hold the hose in place. Route the hose out
through the notch in the back of the top cover.
b. Avoid drain hose runs longer that 30 feet. Make
the valve drain line as short and direct as possible.
c. Run the hose to the floor drain, and as typically
shown in Figure 3, tie or wire the end to a brick or
other heavy object. This will prevent “whipping” dur-
ing recharges. Be sure to provide a 1-1/2" minimum
air gap, to prevent possible sewer water backup (See
“Air Gap Requirements” section).

9. PRESSURE TESTING FOR LEAKS
To prevent excessive air pressure in the EcoWater
Central Water Filtration System and plumbing
system, do the following steps EXACTLY in order:
a. Fully open two or more filtered cold water faucets
nearby the EcoWater Systems filter.
b. Place the bypass valve(s) in bypass position (See
Figures 32 & 33 on Page 22).
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. EXACTLY as follows, place bypass valve(s) into
service:
(1) SINGLE BYPASS VALVE: Slowly move the
valve stem toward service position, pausing sever-
al 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.
e. After about three minutes, open a hot water faucet
for one minute, or until all air is expelled, then close.
f. Close all cold water faucets and check your plumb-
ing work for leaks.
IMPORTANT: Start up procedure must be run prior to
using any filtered water. Follow the instructions at
right and on Page 11.
10. CONNECT TRANSFORMER
a. During installation, the Central Water Filtration
System wiring may be moved or jostled from place.
Check to be sure all leadwire connectors are secure
on the back of the electronic control board (See
Figure 31 on Page 21) and be sure all wiring is away
from the valve gear and motor area, which rotates
during Clean Rinse cycles.
b. Plug the transformer into a continuously “live,”
grounded, 120V, 60Hz house electrical outlet, in a dry
location and approved by local codes. The unit
works on 24V only. Do not connect without the
transformer.
11. SET PRESENT TIME ON THE ELEC-
TRONIC CONTROLLER
In the display, the words “PRESENT TIME” appear
and 12:00 PM begins to flash. Set the clock accord-
ing to the “Set Time of Day” section on Page 12.
12. RUN START UP PROCEDURE
Run the Start Up Procedure, as detailed on Page 11,
to purge the system of fine carbon particles.
13. RESTART THE WATER HEATER
Once the Start Up Procedure has been completed,
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, the hot water will be fully filtered. To
have fully filtered hot water immediately, wait until the
start up procedure (Step 12) is complete, then drain
the water heater until water runs cold.

ECOWATER
SYSTEMS How a Central Water Filtration System Works
NORMAL OPERATION
During normal operation water enters the Central
Water Filtration System and flows through several fil-
tration processes where tastes, odors and sediment
are reduced.
CLEAN RINSE CYCLE
A Clean Rinse cycle will automatically be initiated
based on how many gallons of water have been fil-
tered through the system (or after 14 days if no water
has passed through the system in that time). The
Clean Rinse cycle lifts and expands the media bed to
rejuvenate the media and then repacks the bed for
continued use. During the Clean Rinse cycle, dirt,
sediment, etc. are flushed from the Central Water
Filtration System down the drain.
APPLICATIONS FOR A CENTRAL WATER
FILTRATION SYSTEM
Do not use the Central Water Filtration System with
water that is microbiologically unsafe or of unknown
quality without adequate disinfection before or after
the system.
The Central Water Filtration System may not be an
effective treatment method for water sources with a
hydrogen sulfide problem (rotten egg odor or taste).
The Central Water Filtration System will not remove
iron and is not intended to replace iron treatment
equipment.
Although the Central Water Filtration System has
sediment filter capabilities, additional sediment filtra-
tion may be needed in problem water applications.

11
ECOWATER
SYSTEMS Start Up Procedure
IMPORTANT:
Run the start up cycle immediately after
completing installation, before using any
water in the home.
The filtration media in this Central Water Filtration
System contains a small number of harmless activated
carbon particles generated during shipping that are
small enough to exit the system with water flow. It is
normal for these particles to cause a temporary discol-
oration of the water coming out of the system. To
avoid discolored water at your home’s faucets the sys-
tem’s start up cycle should be initiated to rinse the par-
ticles and any discolored water down the drain.
If the Central Water Filtration System is used without
first running the start up cycle, you will notice that the
water will temporarily have a gray color until the parti-
cles have exited the system.
To Initiate the start up cycle:
1. Make sure the drain hose is attached to the Central
Water Filtration System and the other end is
secured over a drain (see Figure 3 on Page 5).
2. Make sure bypass valve is in the “service” (open or
filtered water) position and the home’s water supply
is turned on.
3. Press and hold the RECHARGE button to initiate
the start up cycle. The button can be released
when you hear the valve changing position and
“RECHARGE NOW” flashes in the display.
During the start up cycle:
Throughout the start up cycle you will hear the valve
changing position and notice the flow of water to drain
starting and stopping. The start up cycle will take
approximately 20 minutes. Avoid using water during
this time. Do not set the time of day or press other
buttons during the start up cycle, as this will interrupt
the start up cycle. Do not unplug the transformer dur-
ing the start up cycle. If the start up cycle is interrupt-
ed, it should be initiated again and allowed to run to
completion.
After the start up cycle:
Once the start up procedure completes successfully, it
cannot be initiated a second time. The Central Water
Filtration System will automatically return to the normal
operation position. Once the start up cycle has run, a
faucet in the home should be opened and water
allowed to run for 10 minutes at the system’s rated
flow. If, after running the start up cycle, the water still
appears discolored, manually run Clean Rinse cycles
(See Page 13) until the water is clear.
If the time of day was not set before the start up cycle,
set it now (See Page 12).
Check the new plumbing connections and joints once
more for leaks.

12
ECOWATER
SYSTEMS Programming the Electronic Controller

START A CLEAN RINSE CYCLE
To manually start a Clean Rinse cycle, press and hold the RECHARGE but-
ton for a few seconds, until “RECHARGE NOW” flashes in the display. This
Clean Rinse cycle takes 3 minutes (unless the factory settings for backwash
and fast rinse times have been changed, as shown below).
SET CLEAN RINSE START TIME
By default the Central Water Filtration System will Clean Rinse at 1:00 a.m.
The system will not filter water during the Clean Rinse cycle. It is recom-
mended that the Clean Rinse start time be set for when water is not likely to
be used in the household.
NOTE: If you also have a water softener, set the Central Water Filtration
System’s Clean Rinse time for either one hour before or two hours
after the water softener’s scheduled regeneration time.
To change the Clean Rinse start time:
1. Press the SELECT button a few times until “RECHARGE TIME” is shown
in the display.
2. Press the UP or DOWN buttons to set the Clean Rinse time in 1
hour increments. Be sure AM or PM is correct.
3. When the desired Clean Rinse time is displayed, press the SELECT but-
ton a few times, until the time appears in the display, but is not flashing.
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.
1. Press and hold the SELECT button for a few seconds, until the “000--”
screen appears, as shown at right.
2. Press the SELECT button once and “12 hr" will flash in the display.
3. Use the UP button to change to a 24 hour clock display.
4. Press the SELECT button several times to advance through the remain-
ing screens and return to the normal operation (time of day) display.
5. To change back to a 12 hour clock, follow Steps 1 through 4, above,
except use the DOWN button in Step 3.
SET LENGTH OF CLEAN RINSE
By default the Central Water Filtration System’s Clean Rinse cycle will con-
sist of a 2 minute backwash followed by a 1 minute fast rinse. This should
be sufficient for most applications.
Increasing the length of Clean Rinse time will increase the amount of water
flushed to drain during each Clean Rinse cycle. Increasing the length of
Clean Rinse should only be done in cases of very high amounts of sedi-
ment, or other water issues.

SETTING THE FREQUENCY OF AUTOMATIC CLEAN RINSE
CYCLES
The Central Water Filtration System will automatically initiate Clean Rinse
cycles based on how much water has been filtered through the system.
The default is to run a Clean Rinse cycle after 3000 gallons have been fil-
tered. The Clean Rinse cycle takes place at the preset time of day (1:00
a.m. is the default). The system also will initiate an automatic Clean Rinse
cycle if no water has been run through the system in 14 days, to keep the
filter bed fresh.
The Central Water Filtration System allows the frequency of automatic
Clean Rinse cycles to be increased for systems where the water supply
may have more sediment than in a typical municipal water supply. The table
below shows the three settings available. The unit is shipped with “CLn 1”
as the default.

OPERATING IN MANUAL CLEAN RINSE MODE
Clean Rinse cycles will run automatically, unless the automatic Clean Rinse
function has been disabled. If this function has been disabled, it will be neces-
sary to manually initiate any Clean Rinse cycles. It is recommended that a
Clean Rinse cycle should be run at least once each month, or more frequently if
necessary.
A manual Clean Rinse mode may be used when a drain (required for automatic
Clean Rinse) is not available. However, it is recommended that automatic
Clean Rinse be used if the drain requirements can be met.
IMPORTANT: During the Clean Rinse cycle, whether manually or automatically
initiated, water will flow from the valve drain port at 3 gallons per min. for 3 min-
utes. If a permanent drain line has not been installed, provisions must be made
for the drain flow prior to initiating a Clean Rinse cycle You must have empty
containers ready that will hold at least 12 gallons of water.
DISABLING AUTOMATIC CLEAN RINSE
To disable the automatic Clean Rinse function:
1. Press and immediately release the RECHARGE button (pressing and holding
the button a few seconds would initiate a Clean Rinse cycle).
2. “VAC” will flash in the display, as shown in Figure 20 indicating that the
Central Water Filtration System is in the manual Clean Rinse mode (the auto-
matic Clean Rinse function has been disabled).
MANUALLY STARTING A CLEAN RINSE CYCLE
To manually start a Clean Rinse cycle:
1. If the drain line is not set up to discharge into a drain, you must have empty
containers ready that will hold at least 12 gallons of water.
2. Press and hold the RECHARGE button for a few seconds, until “RECHARGE
NOW” flashes in the display, as shown in Figure 21.
3. When the Clean Rinse cycle is complete, the Central Water Filtration System
will remain in the manual Clean Rinse mode.
RE-ENABLING AUTOMATIC CLEAN RINSE
To return the Central Water Filtration System to its automatic Clean Rinse func-
tion:
1. Press and immediately release the RECHARGE button.
2. The flashing “RECHARGE OFF” on the display should be replaced by the
normal time of day screen, as shown in Figure 22.
POWER OUTAGE MEMORY
If electrical power to the Central Water Filtration System is lost, “memory'' built
into the controller circuitry will keep all settings for up to eight hours. While the
power is out, the display is blank and the Central Water Filtration System will
not Clean Rinse.
When electrical power is restored, you have to reset the time of day only if the
display is flashing. The Clean Rinse TIME never requires resetting unless a
change is desired. Even if the clock is incorrect after a long power outage, the
Central Water Filtration System works as it should to keep your water treated.
However, Clean Rinse cycles may occur at the wrong time of day until you reset
the clock to the correct time of day.
NOTE: If the Central Water Filtration System was in a Clean Rinse cycle when
power was lost, it will now finish the cycle.

SYSTEMS Care of the Central Water Filtration System
VACATIONS AND EXTENDED PERIODS
OF NO WATER USE
If your Central Water Filtration System will not be
used for an extended period of time (several months),
please follow one of these recommendations:
If the water supply to the unit is not turned off, and
the automatic Clean Rinse function has not been
disabled, then no further actions are required. The
Central Water Filtration System will clean itself
every 14 days if no water has run through it.
If you do not want Clean Rinse cycle to be running
automatically while you are gone, it is recommend-
ed that you unplug the Central Water Filtration
System and either shut off the water supply or
place the bypass valve(s) into the bypass position.
If the Clean Rinse cycle cannot be automatically
run, due to the water supply being shut off, the
transformer being unplugged or the automatic
Clean Rinse function being disabled, then it is rec-
ommended that a minimum of 2 manually initiated
Clean Rinse cycles be performed when the system
is placed back into operation (see Start a Clean
Rinse Cycle section on Page 13).
In any installation where there is a possibility of
freezing, the Central Water Filtration System
should be disconnected and the water drained
(see Protect the Central Water Filtration System
from Freezing section).
PROTECT THE CENTRAL WATER FIL-
TRATION SYSTEM FROM FREEZING
If the Central Water Filtration System is installed
where it could freeze (summer cottage, lake home,
etc.), you must drain all water from it to stop possible
freeze damage. If the system freezes, cracks may
develop in plastic parts, which will leak causing dam-
age.
To drain the unit:
1. Close the shut-off valve on the house main water
pipe, near the water meter or pressure tank.
2. Open a faucet in the filtered water pipes to vent
pressure in the unit.
3. Move the stem in the single bypass valve to
bypass. Close the inlet and outlet valve in a 3
valve bypass system, and open the bypass valve.
If you want water in the house pipes again, reopen
the shut-off valve on the main water pipe.
4. Unplug the transformer at the wall outlet. Take off
the drain hose if it will interfere with moving the
Central Water Filtration System into position over
the drain.
5. Remove the large holding clips at the Central
Water Filtration System inlet and outlet (See Fig-
ures 4 & 5 on Page 6). Separate the unit from the
copper tubes, or from the bypass valve.
6. Lay a piece of 2 inch thick board near the floor
drain (See Figure 23).
7. Move the Central Water Filtration System close to
the drain. Slowly and gently, tip it over until the rim
rests on the wood block with the inlet and outlet
over the drain (See Figure 23). Do not allow the
unit’s weight to rest on the inlet and outlet fittings
or they may break.
8. Tip the bottom of the Central Water Filtration
System up a few inches and rest it on something
like a wood block that will allow water to drain.
Rest the bottom on two stacked wood blocks.
Leave the unit laying like this until you are ready to
use it. Plug the inlet and outlet with clean rags to
keep dirt, bugs, etc. out.

AUTOMATIC ELECTRONIC DIAGNOSTICS
This Central Water Filtration System has a self-diagnostic function for the
electrical system (except input power). The controller monitors electronic
components and circuits for correct operation. If a malfunction occurs, an
error code appears in the display.
The troubleshooting chart on the previous page shows the error codes that
could appear, and the possible malfunctions for each code.
While an error code appears in the display, all buttons are inoperable
except the SELECT button. SELECT remains operational so the service
person can perform the Manual Advance Diagnostics, see below, to further
isolate the problem.
MANUAL ADVANCE DIAGNOSTICS
Use the following procedures to advance the Central Water Filter through
the recharge cycles to check operation.
Remove the top cover by unlocking the two tabs along the back side and
lifting, to observe cam and switch operation during valve rotation.
1. Press and hold SELECT for 3 seconds until “000” shows in the display.
2. The letter “P” and a dash (or dashes) indicate POSITION switch opera-
tion (See Figure 24). If the letter appears, the switch is closed. If the
dash shows, the switch is open.
3. Use the RECHARGE button to manually advance the valve into each
cycle and check correct switch operation.
4. While in this diagnostic screen, the following information is available and
may be beneficial for various reasons. This information is retained by the
computer from the first time electrical power is applied to the electronic
controller.
a. Press the UP button to display the number of days this electronic
control has had electrical power applied (See Figure 25).
b. Press the DOWN button to display the number of recharges initiat-
ed by this electronic control since the code number was entered (See
Figure 26).
5. Press and hold the SELECT button until the model code (“EC”) shows in
the display. This code identifies the filter model. If the wrong number
shows, the filter will operate on incorrect configuration data.
6. To change the code number, press the UP or DOWN button until
the correct code shows.
7. To return to the present time display, press the SELECT button.
