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.
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 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.
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.
The filter works on 24V 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 overcurrent device such as 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
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.

Before Starting Installation
WHERE TO INSTALL THE FILTER
= Place the filter as close as possible to the pressure
tank (well system) or water meter (city water).
= Place the filter as close as possible to a floor
drain, or other acceptable drain point (laundry tub,
sump, standpipe, etc.). CAUTION: Drain water
exits the hose at a fast flow rate, and at water system pressure. Be sure the hose is fastened in
some manner to prevent ”whipping” and splashing
to prevent water damage to surrounding area.
= Connect the filter to the main water supply pipe
UPSTREAM OF the water heater. DO NOT RUN
HOT WATER THROUGH THE FILTER. The temperature of water passing through the filter must
be less than 120°F.
= Keep outside faucets on unfiltered water to con-
serve filtering capacity.
= Do not install the filter in a place where it could
freeze. Damage caused by freezing is not covered by the warranty.
= Put the filter in a place water damage is least likely
to occur if a leak develops. The manufacturer will
not repair or pay for water damage.
= A 120V, 60 Hz electrical outlet, to plug the included
power supply into, is needed near the filter. Be
sure the electrical outlet and power supply are in
an inside location, to protect from wet weather.
= If installing in an outside location, you must take
the steps necessary to assure the filter, installation
plumbing, wiring, etc., are as well protected from
the elements, contamination, vandalism, etc., as
when installed indoors.
= Keep the filter out of direct sunlight. The sun's heat
may soften and distort plastic parts.
TOOLS, PIPE & FITTINGS,
OTHER MATERIALS YOU WILL NEED
= Plastic inlet and outlet fittings included with the fil-
ter allow water flow equivalent to 1 inch nominal
pipe. To maintain full valve flow, 1” pipes to and
from the filter fittings are recommended. Do not
reduce the pipes to less than 3/4” size.
= Use copper, brass or PEX plastic pipe and fittings.
= ALWAYS install the included check valve on the
INLET pipe, immediately upstream of the filter.
= ALWAYS install the included bypass valve, or 3
shut-off valves. Bypass valves let you turn off
water to the filter for repairs if needed, but still
have water available to the house pipes.
= Drain hose 5/8” inside diameter minimum, with a
garden hose connection on one end, is needed for
the valve drain. See step 5 on page 8.
= If a rigid valve drain is needed, to comply with
plumbing codes, you can buy the parts needed
(see page 6) to connect a 5/8” minimum copper
tubing drain.
PLAN HOW YOU WILL INSTALL THE FILTER
You must first decide how to run in and out pipes to
the filter. Look at the house main water pipe at the
point where you will connect the filter. Is the pipe soldered copper, glued plastic, or threaded brass/galvanized? What is the pipe size?
Now look at the typical installation illustration on page
6. Use it as a guide when planning your particular
installation. Be sure to direct incoming, unfiltered
water to the filter valve inlet fitting. The valve ports
are marked IN and OUT.

1. TURN OFF WATER SUPPLY
a. Close the main water supply valve near the well
pump or water meter.
b. Shut off the electric or fuel supply to the water
heater.
c. Open high and low faucets to drain all water from
the house pipes.
2. INSTALL BYPASS VALVE AND/OR
PLASTIC INSTALLATION ADAPTORS:
a. If installing a single bypass valve, push the bypass
valve, with lubricated o-ring seals in place, into the
valve inlet and outlet ports (See Figures 3 & 6).
- OR -
b. If installing a 3-valve bypass system, slide plastic
installation adaptors, with lubricated o-ring seals in
place, into the valve inlet and outlet ports (See
Figures 4 & 6).
c. Be sure the check valve is in place in the valve
inlet, with the flow arrow pointed inward, as shown
in Figure 6.
d. Be sure the turbine support is in place in the valve
outlet, as shown in Figure 7.
e. Snap the two large plastic clips in place on the inlet
and outlet ports, from the top, down (See Figure 8).
Be sure they snap into place. Pull on the bypass
valve, or installation adaptors, to make sure they
are held securely in place.
3. COMPLETE PLUMBING TO AND FROM
THE FILTER
Using the “Typical Installation Illustration” on page 6
as a guide, observe all of the following cautions while
you connect inlet and outlet plumbing:
= Be sure incoming, unfiltered water is directed to
the valve INLET port.
= Be sure to install the included check valve on
the INLET pipe, immediately upstream of the filter,
as shown in the “Typical Installation Illustration” on
page 6. Note the direction of the flow arrow on the
check valve.
= Be sure to install bypass valve(s).
= If making a soldered copper installation, do all
sweat soldering before connecting pipes to the filter fittings. Torch heat will damage plastic parts.
= Use pipe joint compound on all external pipe
threads.
= When turning threaded pipe fittings onto plastic fit-
tings, use care not to cross-thread.
= Support inlet and outlet plumbing in some manner
(use pipe hangers) to keep the weight off of the
valve fittings.

4. COLD WATER PIPE GROUNDING
CAUTION: 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 4, will
maintain ground continuity. If you use a
plastic bypass valve at the unit, continuity
is broken. To restore the ground, do the
following:
a. Install a #4 copper wire across the removed sec-
tion of main water pipe, securely clamping it at
both ends (See Figure 10) - parts not included.
NOTE: Check local plumbing and electrical codes for
proper installation of grounding. The installation must conform to them. In Massachusetts,
plumbing codes of Massachusetts shall be
conformed to. Consult with your licensed
plumber.
5. INSTALL VALVE DRAIN HOSE
a. Take a length of 5/8” inside diameter garden hose
and attach to the valve drain fitting (See Figure 5
on page 6).
b. Locate the other end of the hose at a suitable drain
point (floor drain, sump, laundry tub, etc.). Check
and comply with local codes. Refer to Figure 5 on
page 6 if codes require a rigid pipe drain run.
IMPORTANT: Use high quality, thick wall hose that
will not easily kink or collapse. The filter will not backwash properly if water
cannot exit this hose during recharges.
c. Tie or wire the hose in place at the drain point.
Water pressure will cause it to whip during the
backwash portion of the recharge cycle. Also provide an air gap of at least 1-1/2” between the end
of the hose and the drain point. An air gap prevents possible siphoning of sewer water, into the
filter, if the sewer should back up.
d. If raising the drain hose overhead is required to get
to the drain point, do not raise higher than 8 feet
above the floor. Elevating the hose may cause a
back pressure that could reduce backwash flow
and proper mineral bed cleaning.
6. FLUSH PIPES AND TEST FOR LEAKS
AUTION: To avoid water or air pressure damage to
C
filter inner parts, be sure to do the following steps exactly as listed:
. Fully open two filtered water faucets, one cold and
a
one hot, nearby the filter.
b. Place bypass valve(s) into “bypass” position. On a
single valve, slide the stem inward to BYPASS
(See Fig. 5 on page 6). On a 3 valve system,
close the inlet and outlet valves, and open the
bypass valve (See Fig. 4 on page 6).
c. Fully open the house main water pipe shutoff valve.
Observe a steady flow from both opened faucets.
d. Close both faucets.
e. Check your plumbing work for leaks and, if any are
found, fix right away. Be sure to observe previous
caution notes.
f. Turn on the gas or electric supply to the water
heater. Light the pilot, if applicable.
7. CONNECT TO ELECTRICAL POWER:
The filter controller works on 24V DC electrical power.
The included power supply converts 120V AC household power to 24V DC. Plug the power supply into a
120V, 60 Hz electrical outlet. Be sure the outlet is
always “live” so it can not be switched off by mistake.
8. PROGRAM THE CONTROLLER
See pages 10-11 for instructions to program the electronic controller.
9. START UP PROCEDURE
a. Confirm that the filter’s main valve is in the “service”
position (“S” on the cam).
b. Place bypass valve(s) into “service”, EXACTLY as
follows:
= Single Bypass Valve: SLOWLY, pull the valve
stem outward to ”service” position, pausing several times to allow the filter to pressurize slowly.
= 3 Valve Bypass: Fully close the bypass valve
and open the outlet valve. SLOWLY, open the
inlet valve, pausing several times to allow the
filter to pressurize slowly.
c. Check all connections for leaks.
d. Push and hold the RECHARGE button until the fil-
ter starts a RECHARGE NOW cycle. Verify that
the valve advances to “backwash” (BW) position.
e. Allow the unit to remain in “backwash” (BW) while
air is purged and water exits the drain line. Ensure
that the drain line is secure and will withstand the
mix of air and water exiting.
f. Allow the unit to complete the 15 minute “backwash”
cycle and automatically advance to the “aspirate” (A)
position. Allow it to remain there as it aspirates air
into the mineral tank. After 75 minutes, the filter will
then automatically return to “service”. Start up is
complete.

Sanitizing Procedure
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,
during shipping, storage, installing and operating,
bacteria could get into the filter or media. For this
reason, sanitizing as follows is suggested* when
installing.
1. Obtain pharmaceutical grade 12% hydrogen perox-
ide solution. One quart (0.95 L) is required for a
10" filter, 2 quarts (1.9 L) for a 12" filter.
2. Remove air inlet screen from check valve on the
valve’s nozzle & venturi assembly (See Figure 11).
3. Connect a length of 3/8 I.D. tubing to the barb on
the aspirator check valve (See Figure 12).
4. Insert the free end of the tubing into the hydrogen
peroxide container.
5. Push and hold the RECHARGE button until the fil-
ter starts a RECHARGE NOW cycle. The filter will
backwash for 15-17 minutes, then advance automatically to the “aspirate” position. It will draw the
hydrogen peroxide into the filter and pass it
through the zeolite media, cleaning and sanitizing
the media.
6. Allow the filter to draw air for the remainder of the
time in the “aspirate” cycle after the hydrogen peroxide has been drawn into the filter.
7. The filter will return to “service” automatically when
the “aspirate” cycle is complete.
8. Remove tubing and reinstall the aspirator inlet
screen onto the barbed fitting on aspirator check
valve.
9. Cleaning/sanitizing process is complete.
*NOTE:
Sanitizing is recommended by the Water Quality
Association for disinfecting. On some water supplies, they suggest periodic sanitizing.

POWER OUTAGE MEMORY
If electrical power to the filter’s control is lost, internal
memory will maintain most settings such as the days
between recharge and recharge time. However,
unless the power outage was very brief, the clock’s
present time will need to be reset. During a power
outage, the display will be blank and the filter will not
recharge. When electrical power is restored:
1. Check the display.
2a. If the present time is displayed steadily (not flash-
ing), the controller did not lose time and you do
not need to reset the clock.
2b. If a time is flashing in the display, then the clock
needs to be reset to the correct present time.
See “Set Present Time of Day” on page 10. The
flashing display is to remind you to reset the
clock. If you do not reset the clock, then
recharges will most likely occur at the wrong time
of day.
NOTE: If the filter was recharging when power was
lost, it will finish the cycle when power returns.
RECHARGE NOW
For times when you expect to use more water than
usual, it may be desirable to perform a manually initiated recharge. To manually start a recharge cycle,
press and hold the RECHARGE button for a few seconds, until “RECHARGE NOW” flashes in the display.
The filter begins an immediate backwash. Once
started, you cannot cancel this recharge. Avoid using
hot water during this time, as the water heater will
refill with unfiltered water.
FIG. 19
VACATION CONTROL
1. Before going on vacation, or other long absence,
press (but do not hold) the TOUCH/HOLD button, so
that “VAC” begins to flash in the display. The timer
continues to keep time, but recharges will not occur,
saving water.
FIG. 20
2. When you return, press the TOUCH/HOLD button
again. This cancels the flashing “VAC” and returns
the filter to normal service. You must remember to do
this, or the filter will not recharge.

RECHARGE CYCLE TIME ADJUSTMENTS
The default setting for backwash and aspirate times
of the recharge cycle are factory set for maximum
performance of the filter. Use the following procedures to check for correct cycle times, or to change, if
desired. It is recommended that only trained technicians should change the time settings.
NOTE: Fill and brine times are adjustable, but set at
the factory to zero. It is recommended to
leave these settings at zero, unless the filter is
used in a custom application by the installer.

Routine Maintenance
CLEANING THE NOZZLE & VENTURI
A clean nozzle & venturi (See Figure 26) is a necessity for the water filter to work properly. This small
component creates the suction to aspirate (bring air
into) the mineral tank during recharges. If it should
become plugged with sand, silt, dirt, etc., the water filter will not work to remove iron from the water.
To get access to the nozzle & venturi, remove the
water filter’s top cover. Put the bypass valve(s) into
the bypass position. Be sure the water filter’s main
valve is in “service” position (no water pressure at
nozzle & venturi). Then, holding the nozzle & venturi
housing with one hand, unscrew the cap. Do not lose
the o-ring seal. Lift out the screen support and
screen. Then, remove the nozzle & venturi disc, gasket and flow plug. Wash the parts in warm, soapy
water and rinse in fresh water. Be sure to clean both
the top and bottom of the nozzle & venturi disc. If
needed, use a small brush to remove iron or dirt. Do
not scratch, misshape, etc., surfaces of the nozzle &
venturi.
Gently replace all parts in the correct order. Lubricate
the o-ring seal with silicone grease and locate in
place. Install and tighten the cap by hand, while supporting the housing. Overtightening may break the
cap or housing. Put the bypass valve(s) into “service”
position.

Troubleshooting
AUTOMATIC ELECTRONIC DIAGNOSTICS
This filter has a self-diagnostic function for the electrical system. The computer monitors electronic components and circuits for correct operation. If a malfunction occurs, an error code appears in the display.
FIG. 27
The chart below shows the error codes that could
appear, and the possible malfunctions for each code.
Code Possible Problems
Err01 Motor, Valve Position Switch
Err03 Motor, Valve Position Switch, Wire Harness
Err04 Valve Position Switch
Err05 Electronic Control Board (PWA)
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 Manually Initiated Electronic Diagnostics to
further isolate the problem.
TO REMOVE AN ERROR CODE:
1. Unplug the power supply.
2. Correct the problem.
3. Plug the power supply back in.
4. Wait for at least 8 minutes while the timer operates
the valve through an entire cycle. The error code
will return if the problem was not corrected.
MANUALLY INITIATED ELECTRONIC
