SAFETY GUIDES
Follow the installation instructions carefully. Failure to
install the filter 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.
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-sold-
er 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 oc-
cur. Do not attempt to filter 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 filter requires a minimum water flow of 5 gallons
per minute at the inlet for backwash. Test water flow if
in doubt.
Recommended maximum allowable inlet water
pressure is 80 psi. Use a pressure reducing valve if
necessary. Be sure the addition of a pressure reducing
valve will not reduce the flow to less than the 5 gallons
per minute needed for backwash.
This filter controller works on 24 Volt, 60 Hz electri-
cal power only. Be sure to use the included transformer
and plug it into a nominal 120V, 60 cycle household out-
let that is grounded and properly protected by an over
current device such as a circuit breaker or fuse. If trans-
former is replaced, use only the authorized service,
class II, 24 Volt, 10 VA transformer. The relay box for the
air pump must be plugged into a separate 120V
grounded household outlet.
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 sys-
tem.
European Directive 2002/96/EC requires all elec-
trical 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.

den hose, or hose onto a barb fitting*
*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, pur-
chase an adaptor, garden hose thread x 5/8” (mini-
mum) tube. Use a hacksaw to cut 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 recharge
discharge water. A standpipe is preferred, with a
laundry tub, floor drain, etc., as other options
(check your local codes).
SThe filter works on 24 volts only. A transformer is
included (FOR INDOOR USE) to reduce 120V,
60 Hz house electrical power. Provide an ap-
proved, grounded outlet within 10’ of the filter.
The filter includes a 10’ power cable for connec-
tion between the transformer and the timer. The
relay box also requires a suitable live, grounded
outlet.
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.

SANITIZING THE FILTER
Care is taken at the factory to keep your 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. or 2 oz. 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.
SANITIZING WILL BE CONTINUED IN STEP 9,
PAGE 11, AND STEP II ON PAGE 12.
1. INSTALL SINGLE BYPASS VALVE and/or
COPPER TUBES
NOTE: All fittings are in the parts bag.
a. Push the bypass valve, with lubricated o--ring
seals in place, into the valve inlet and outlet ports,
Figure 4. Be sure the o--ring sealing surface is clean.
-- A N D / O R --
b. Slide copper tubes, with lubricated o--ring seals
in place, into the filter valve or bypass valve inlet and
outlet ports, Figure 5. Be sure the o--ring sealing
surface is clean.
NOTE: Be sure the turbine and support are in place
in the valve outlet, as shown in Figures 4 and 5.
c. Snap the two large plastic clips into place, from
the top down, Figure 4 and Figure 5. Be sure they
snap into place. Pull on the copper tubes, or bypass
valve, to make sure they are held securely in place.
NOTE: For lubrication, use silicone grease ap-
proved for use on potable water supplies.

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
house pipes.
3. INSTALLING 3--VALVE BYPASS
If installing a 3--valve bypass system, plumb as
needed. 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.
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 & 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 installed, will maintain
ground continuity. If you use the plastic bypass
valve at the filter, continuity is broken. To restore the
ground, install one of the following grounds.
a. Use the included ground clamp kit to jumper
across the inlet and outlet copper tubes Figure 6a.
b. Install a #4 copper wire across the removed sec-
tion of main water pipe, securely clamping on both
ends, Figure 6b.
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 1. The
elbow accepts standard garden hose onto the
threads.
NOTE: Flexible drain hose is not allowed in all locali-
ties. See option on page 6.
b. Route the hose to the drain point (standpipe,
laundry tub, floor drain, etc.) as typically shown in
Figure 1. Affix the end of the hose securely to
prevent “whipping” during recharges. Be sure to pro-
vide a 1--1/2” minimum air gap, to prevent possible
sewer water backup.
NOTE: Avoid long drain hose runs, or elevating the
hose.
9. INSTALL VENT TUBE
a. Locate the 20’ coil of 1/4” O.D. tubing inclded with
the filter. Connect one end of the tubing to the outlet
port of the solenoid valve, Figure 2.
NOTE: Do not cut the vent tubing -- use the entire 20’
length.
b. Route the vent tubing to the drain point
(standpipe, laundry tub, floor drain, etc.) as typically
shown in Figure 1. Affix the end of the tube
securely, as water and air will exit this vent with
force.
10. 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.
e. Check your complete installation for leaks. If re-
work is required, be sure to observe precautions in
step 6.
11. CONNECT ALL LEADWIRES
a. Locate the power cable, which is shipped with one
end plugged into the timer (PWA) under the top
cover. Refer to Figure 8. Attach the other end of the
power cable to the transformer.
NOTE: Check to be sure the connector is secure on
the back of the timer.
b. Plug the leads from the relay box into the
corresponding connectors of the wire harness,
located near the solenoid under the top cover.
12. CONNECT AIR PUMP
a. On the floor or a shelf nearby the filter, fasten the
air pump in place.
b. Install the air filter (if required) and tubing connec-
tor fitting.
c. Connect the tubing from the check valve, on the
adaptor, to the connector fitting on the air pump.
d. Plug the pump into the relay box connector.
13. CONNECT TO ELECTRICAL POWER
Plug both the transformer and relay box into continu-
ously “live”, grounded, 120V, 60Hz house electrical
outlets, approved by local codes.
14. TO COMPLETE INSTALLATION, DO THE PRO-
GRAMMING STEPS ON PAGES 11 AND 12.

After completing the preceding installation and programming steps, check all the
following:
DMake sure the bypass valve(s) are in the “service” position.
DCheck for leaks.
DOpen a filtered water faucet and confirm that the air pump runs. Pump will run for
8 seconds after water flow has stopped.
DMake sure the ball valve on the neck adaptor is open. See Figure 10.
DMake sure the solenoid vent is open when the air pump is running.
DMake sure the vent tube is held securely at the drain point. Air/water mixture
exits the vent tube with force. Observe the vent tube for at least 10 minutes
while air pump is running and solenoid is open to ensure that vent tube is held
securely and will not become dislodged from the drain.

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
filter backwashes for 25 minutes, followed by a 5
minute fast rinse cycle. Then the filter returns to ser-
vice.
VACATION -- The day you leave on vacation, or oth-
er long absence, press (DO NOT HOLD IN) the RE-
CHARGE keypad. VAC begins to flash in the
display. The timer will keep time, but the filter will not
backwash and waste water.
NOTE: While in the VACATION setting, the filter will
go through a backwash if the RECHARGE NOW
feature is used (see above).
WHEN YOU RETURN, press the RECHARGE key-
pad again to return the filter to service, and the cor-
rect time of day will show in the display. Remember
to do this or the filter will not backwash and you
will have unfiltered water.
The default settings for backwash (25 minutes) and
fast rinse (5 minutes) cycles of recharge 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 BACKWASH -- Press and hold the
SELECT button until the display shows “000----”,
then press the SELECT button once to advance to
the Backwash time adjust screen.
Using the UP or DOWN buttons, adjust the back-
wash time from 0 minutes to 60 minutes.
ADJUSTABLE FAST RINSE -- Press and hold the
SELECT button until the display shows “000----”,
then press the SELECT button twice to advance to
the Fast Rinse time adjust screen.
Using the UP or DOWN buttons, adjust the fast rinse
time from 0 minutes to 60 minutes.
NOTE:Fill and brine times are adjustable, but preset
at the factory to zero minutes. It is recommended to
leave these settings as preset, unless the filter is
used in a custom application by the installer.
TIMER “POWER--OUTAGE MEMORY” -- If electri-
cal power to the timer is interrupted, the “memory”
built into timer circuitry keeps time settings for
several hours (minimum) or more. The display is
blank and the filter will not recharge. When electrical
power comes on, one of two things will happen.
1. The present time of day will show steady, meaning
the timer has not lost time.
2. The display will show a time, but it will be flashing.
The timer memory did not keep the time setting and
must be reset (page 11). If you do not reset the time
setting, recharges 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.

Filter Operation
ECOWATER
S YST E MS
GENERAL INFORMATION
The air injector adaptor installs between the filter
valve and mineral tank. A pump injects air into the
iron filter through the adaptor. The air oxidizes iron
and it is mechanically filtered by the filter mineral
bed. The injector adaptor float allows excess air to
vent from the tank.
SERVICE, BACKWASH AND FAST RINSE
SERVICE (Figure 11): 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 12): 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 13): 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.

Adaptor Troubleshooting Guide
If excess air is in household plumbing, the air vent is
most likely plugged with debris.
Close the ball valve. Then disconnect tubing from
solenoid inlet, as shown below. Remove the inlet
screen, located inside the inlet port of the solenoid.
Clean and reinstall the inlet screen.
After vent is cleared, reconnect tubing,
open ball valve and check for leaks.

Description of Operation -- Air pump activation & solenoid venting system
When service water flows through the filter, it rotates the turbine (located in the valve’s outlet port), sending a
signal to the controller (PWA). The controller then activates a 24V power supply to the vent solenoid and relay
box. When activated, the relay box turns on the 120V power supply to the air pump. The air pump adds a head of
air in the filter tank. This supplies oxygen that aerates the water and oxidizes iron, manganese and hydrogen
sulfide (generating particles). The vent solenoid is opened during this time, permitting oxygen--depleted air to
escape and be continuously replaced in the tank by fresh air. After oxidation, the birm filtration media filters out
the particles. During the backwash / rinse cycles, the filter cleans itself. During regenerations the air pump and
vent solenoid do not activate. After service water flow stops, the air pump will run for an additional 8 seconds.
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.

2. Plumbing bypass valve(s) must be in SERVICE
position (see Figure 7, page 8).
3. The inlet and outlet pipes must connect to the filter
inlet and outlet respectively.
4. Is the transformer 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.
6. If the air pump is not running, check for binding of
the turbine, check that the leads of the relay box are
connected to the back of the faceplate and there is
power to the relay box.
If you do not find the problem after making the initial
checks, do the MANUAL ADVANCE DIAGNOS-
TICS.
