Recommended maximum allowable inlet water
pressure is 80 psi. Use a pressure reducing valve if
necessary. Be sure the addition of a pressure reduc-
ing valve will not reduce the flow to less than the 5
gallons per minute needed for backwash.
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 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) require-
ments. 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 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-sol-
der 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.
reezing, 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.

Before Starting Installation
WHERE TO I STALL 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.). CAUTIO : Drain water
exits the hose at a fast flow rate, and at water sys-
tem 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 O the water heater. DO NOT RUN
HOT WATER THROUGH THE ILTER. The tem-
perature of water passing through the filter must
be less than 120° .
=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 cov-
ered 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 & FITTI GS,
OTHER MATERIALS YOU WILL EED
=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.
PLA HOW YOU WILL I STALL 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 sol-
dered copper, glued plastic, or threaded brass/galva-
nized? 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.

Media Loading (Model NSEIV-10)
MEDIA LOADI G
Model SEIV-10, as manufactured, has no media
other than quartz gravel at the bottom of the tank
(See table on Page 3 for amount). Before plumbing
this unit, load media:
1. Move the filter into installation location and set it on
a flat, level surface. If a twin installation, keep
tanks separated for ease of service.
2. Take off the unit’s top cover and unplug the wiring
connections between the valve and the control
board (PWA).
3. Remove retainer clips and clamp sections from the
tank neck and carefully lift the valve off the tank.
4. Check the height of the riser pipe as shown in
igure 3. If riser pipe is more than 1/2” above the
top distributor, make sure that bottom distributor is
below gravel at the bottom of the tank. It may be
necessary to lay the filter on its side to move gravel
to one side, hold the bottom distributor at the bot-
tom center of the tank and stand the unit back up.
Level gravel after checking.
5. After confirming the riser pipe height, remove the
top distributor from the tank neck, leaving the bot-
tom distributor (including riser pipe) in place, cen-
tered in the tank.
6. Cover the top end of the riser pipe with a clean
rag, to keep media out (See ig. 4).
7. Using a larger neck funnel, add the necessary
amount of media.
8. lush the tank opening with water to clean media
particles from the top of the tank. Uncover the bot-
tom distributor stand tube.
9. ill the tank with water, up to the top of the tank.
IMPORTA T: Be sure to fill with water. This will elim-
inate air space, wet the media and pre-
vent excessive air-head pressure when
filter is pressurized.
10. Install the o-ring seals and top distributor exactly
as shown in igure 5. Place the small o-ring at
the top of the riser pipe, where shown in igure 3.
If the o-rings need lubrication, use a high quality
silicone grease.
11. Lower the valve assembly onto the tank, centering
over the riser tube. Push downward, against the
o-ring, and install the clamp sections, securing
with the retainer clips.
12. Verify that the backwash flow plug (See Key No. 59
on Page 18) is appropriately sized for the media
used. If necessary, install a different flow plug.

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 igures 6 & 9).
- 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
igures 7 & 9).
c. Be sure the check valve is in place in the valve
inlet, with the flow arrow pointed inward, as shown
in igure 9.
d. Be sure the turbine support is in place in the valve
outlet, as shown in igure 10.
e. Snap the two large plastic clips in place on the inlet
and outlet ports, from the top, down (See igure
11). 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 PLUMBI G TO A D 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 I LET port.
=Be sure to install the included check valve on
the I LET 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 fil-
ter 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.

b. Place bypass valve(s) into “bypass” position. On a
single valve, slide the stem inward to BYPASS
(See ig. 8 on page 6). On a 3 valve system,
close the inlet and outlet valves, and open the
bypass valve (See ig. 7 on page 6).
c. ully 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. CO ECT TO ELECTRICAL POWER:
The filter controller works on 28V DC electrical power.
The included power supply converts 120V AC house-
hold power to 28V 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 CO TROLLER
See pages 10-11 for instructions to program the elec-
tronic 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 sev-
eral times to allow the filter to pressurize slowly.
=3 Valve Bypass: ully 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.
4. I STALL GROU D CLAMP (IF EEDED):
If the home’s cold water piping is being used for elec-
trical grounding, a 3 valve bypass system maintains
ground continuity. If you are using a single plastic
bypass valve, install the included ground clamp, as
shown In igure 13, to maintain electrical ground conti-
nuity in the house cold water piping. Be sure the pipes
are clean, under the clamps, to assure good contact.
5. I STALL VALVE DRAI HOSE
a. Take a length of 5/8” inside diameter garden hose
and attach to the valve drain fitting (See igure 8
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 igure 8 on
page 6 if codes require a rigid pipe drain run.
IMPORTA T: Use high quality, thick wall hose that
will not easily kink or collapse. The fil-
ter 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 pro-
vide an air gap of at least 1-1/2” between the end
of the hose and the drain point. An air gap pre-
vents 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 A D TEST FOR LEAKS
CAUTIO : To avoid water or air pressure damage to
filter inner parts, be sure to do the follow-
ing steps exactly as listed:
a. ully open two filtered water faucets, one cold and
one hot, nearby the filter.

Sanitizing Procedure
9
Description of Operation
Service water enters the filter and passes through air
captured at the top of the mineral tank. Dissolved iron
is oxidized and then removed by the media in the
tank. When the system recharges, it first backwash-
es the contaminants to the drain, then empties the
tank of water, replacing it with air drawn through the
aspirator. When the system returns to "service", the
water pressure will compress the air in the mineral
tank and leave an 8-14" head of air on the top of the
tank.
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. or 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 igure 14).
3. Connect a length of 3/8 I.D. tubing to the barb on
the aspirator check valve (See igure 15).
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 auto-
matically 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 per-
oxide 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.
*OTE: Sanitizing is recommended by the Water Quality
Association for disinfecting. On some water sup-
plies, they suggest periodic sanitizing.

2. The filter’s default recharge start time is 12:00 AM.
This is normally a time of day when water is not
being used in the household. If you have a water
softener or another filter installed, the recharge
start times should be offset to assure adequate
water flow and pressure. or example, if the water
softener is set to begin recharge at 2:00 AM, set
the filter to start recharge at 12:00 AM, or 4:00 AM.
Use the rUP or sDOWN buttons to adjust the
recharge start time.

or times when you expect to use more water than
usual, it may be desirable to perform a manually initi-
ated recharge. To manually start a recharge cycle,
press and hold the RECHARGE button for a few sec-
onds, 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. 22
VACATIO CO TROL
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.
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.
FIG. 23
ORMAL OPERATIO
During normal operation, the present time of day
shows in the display.
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.
OTE: If the filter was recharging when power was
lost, it will finish the cycle when power returns.

RECHARGE CYCLE TIME ADJUSTME TS
The default setting for backwash and aspirate times
of the recharge cycle are factory set for maximum
performance of the filter. Use the following proce-
dures to check for correct cycle times, or to change, if
desired. It is recommended that only trained techni-
cians should change the time settings.

AUXILIARY OUTPUT CO TROL
The electronic controller’s auxiliary output may be
used to operate various types of external equipment,
such as a chlorine generator or chemical feeder. It
provides a 28V DC, up to 300 mA, current from termi-
nal J4 on the electronic control board (see Schematic
on Page 16). The table below explains the choices
available for when the auxiliary output will be on dur-
ing various portions of the recharge cycle:
The default is O . If you wish to change to one of
the other selections shown in the table above:
1. Press and hold the SELECT button until “000 - -”
shows in the display.
2. Press the SELECT button three times and “Ctrl"
will flash in the display.
3. Use the rUP or sDOWN buttons to display the
desired selection, then press the SELECT button.
If you selected anything other than C , the display
will return to the normal run (time of day) screen.
If setting to C (Chemical eeder), there will be
two additional settings to make for operating the
chemical feeder in Steps 4 and 5, on the next
page.

CLEA I G THE OZZLE & VE TURI
A clean nozzle & venturi (See igure 29) is a necessi-
ty 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 fil-
ter 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, gas-
ket 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 sup-
porting the housing. Overtightening may break the
cap or housing. Put the bypass valve(s) into “service”
position.
Nozzle & Venturi Disc
IMPORTANT: Be sure small hole in the gasket is cen-
tered directly over the small hole in the nozzle & ven-
turi housing. Be sure the numbers are facing up
Recharge the filter and advance the valve to the
“aspirate” (A) position. Remove the screen from the
barbed fitting on the inlet of the check valve and
determine whether there is suction. Put the screen
back in place when finished checking.

MA UALLY I ITIATED ELECTRO IC
DIAG OSTICS
Use the following procedures to advance the filter
through the recharge cycles to check operation.
Remove the top cover faceplate assembly by unlock-
ing the tabs and lifting, to observe cam and switch
operation during valve rotation (See igure 32).
1. Press and hold for 3 seconds the SELECT button,
until one of the screens shown in igure 31 is dis-
played. If the valve is in service, backwash or
aspirate position (observe markings on the valve
cam), the display should show “000 - -”, meaning
the position switch is open. When the valve is
moving, the display should show “000 - P”, mean-
ing that the position switch is closed.
FIG. 31
2. Use the TOUCH/HOLD button to manually advance
the valve into each position and check correct switch
operation (See igures 33-35).
3. While in the “aspirate” (A) position, check the noz-
zle & venturi by removing the screen from the
barbed fitting on the inlet of the check valve and
determining whether there is suction. Put the
screen back in place when finished checking.
4. While in this diagnostic screen, the following infor-
mation is available and may be beneficial for vari-
ous reasons. This information is retained by the
computer from the first time electrical power is
applied to the electronic controller.
a. Press the rUP button to display the number of
days this electronic control has had electrical
power applied.
b. Press the sDOWN button to display the num-
ber of automatic or manual recharges initiated
by this electronic control since the model code
number was entered.
5. Press the SELECT button and hold in for 3 sec-
onds until the model code shows in the display.
The model code should be “HAAI ”. If the wrong
number shows, the filter will operate on incorrect
configuration data.
6. To change the code number - Press the rUP or
sDOWN button until the correct code shows.

AUTOMATIC ELECTRO IC DIAG OSTICS
This filter has a self-diagnostic function for the electri-
cal system. The computer monitors electronic com-
ponents and circuits for correct operation. If a mal-
function occurs, an error code appears in the display.
FIG. 30
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 per-
form the Manually Initiated Electronic Diagnostics to
further isolate the problem.
TO REMOVE A 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.
