*Capacity to reduce clear water iron is substantiated by WQA test data. State of Wisconsin requires additional
treatment if water supply contains clear water iron exceeding 5 ppm.
These systems conform to NSF/ANSI 44 for the specific performance claims as verified and substantiated by
test data.
Variable Salt Dose: The salt dose is selected by the electronic controls at regeneration time based on the
amount needed.
These models are efficiency rated. The efficiency rating is valid only at the minimum salt dose. These softeners
have a demand initiated regeneration (D.I.R.) feature that complies with specific performance specifications intended
to minimize the amount of regenerant brine and water used in their operation.
These softeners have a rated softener efficiency of not less than 3,350 grains of total hardness exchange per pound
of salt (based on sodium chloride) and shall not deliver more salt than their listed rating or be operated at a sus-
tained maximum service flow rate greater than their listed rating. These softeners have been proven to deliver soft
water for at least ten continuous minutes at the rated service flow rate. The rated salt efficiency is measured by lab-
oratory tests described in NSF/ANSI Standard 44. These tests represent the maximum possible efficiency that the
system can achieve. Operational efficiency is the actual efficiency after the system has been installed. It is typically
less than the rated efficiency, due to individual application factors including water hardness, water usage, and other
contaminants that reduce a softener's capacity.

=The water softener requires a minimum water flow of 3 gallons (11.4 L) per minute at the inlet. Maximum allow-
able inlet water pressure is 100 psi (7.0 kg/cm2). If your house water pressure is over the maximum, install a
pressure reducing valve in the water supply pipe to the system (Adding a pressure reducing valve may reduce
the flow). If your home is equipped with a back flow preventer, an expansion tank must be installed in accordance
with local codes and laws.
=The water softener 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 a circuit breaker or fuse.
=Do not use this system to treat water that is microbiologically unsafe or of unknown quality without adequate dis-
infection upstream or downstream of the system.
uropean Directive 2002/96/ C requires all electrical and electronic equipment to be disposed of accord-
ing to Waste lectrical and lectronic quipment (W ) 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 prop-
er disposal of this equipment.

Water Conditionin Information
IRON
Iron in water can cause stains on clothing and plumb-
ing fixtures. It can negatively affect the taste of food,
drinking water, and other beverages. Iron in water is
measured in parts per million (ppm). The total* ppm of
iron, and type or types*, is determined by chemical
analysis. Four different types of iron in water are:
=Ferrous (clear water) iron
=Ferric (red water) iron
=Bacterial and organically bound iron
=Colloidal and inorganically bound iron (ferrous or
ferric)
Ferrous (clear water) iron is soluble and dissolves in
water. This water softener will reduce moderate
amounts of this type of iron (see specifications).**
Ferrous (clear water) iron is usually detected by taking
a sample of water in a clear bottle or glass.
Immediately after taking, the sample is clear. As the
water sample stands, it gradually clouds and turns
slightly yellow or brown as air oxidizes the iron. This
usually occurs in 15 to 30 minutes.
When using the softener to reduce Ferrous (clear
water) iron, add 5 grains to the hardness setting for
every 1 ppm of Ferrous (clear water) iron. See "Set
Water Hardness Number" section.
Ferric (red water), and bacterial and organically bound
irons are insoluble. This water softener will not
remove ferric or bacterial iron. This iron is visible
immediately when drawn from a faucet because it has
oxidized before reaching the home. It appears as
small cloudy yellow, orange, or reddish suspended
particles. After the water stands for a period of time,
the particles settle to the bottom of the container.
Generally these irons are removed from water by filtra-
tion. Chlorination is also recommended for bacterial
iron.
Colloidal and inorganically bound iron is of ferric or fer-
rous form that will not filter or exchange out of water.
This water softener will not remove colloidal iron. In
some instances, treatment may improve colloidal iron
water. Colloidal iron water usually has a yellow
appearance when drawn. After standing for several
hours, the color persists and the iron does not settle,
but remains suspended in the water.
SEDIMENT
Sediment is fine, foreign material particles suspended
in water. This water softener will not remove sedi-
ment. This material is most often clay or silt. xtreme
amounts of sediment may give the water a cloudy
appearance. A sediment filter installed upstream of the
water softener normally corrects this situation.
* Water may contain one or more of the four types of
iron and any combination of these. Total iron is the
sum of the contents.
** Capacity to reduce clear water iron is substantiated
by WQA test data.
The parts required to assemble and install the water
softener are included with the unit. Thoroughly check
the water softener for possible shipping damage and
parts loss. Also inspect and note any damage to the
shipping carton.
Remove and discard (or recycle) all packing materials.
To avoid loss of small parts, we suggest you keep the
small parts in the parts bag until you are ready to use
them.

P UMBING CODES
All plumbing must be completed in accordance with
national, state and local plumbing codes.
AIR GAP REQUIREMENTS
A drain is needed for regeneration water (See Figure
3). A floor drain, close to the water softener, is
preferred. A laundry tub, standpipe, etc. are other
drain options. Secure valve drain hose in place.
Leave an air gap of 4 cm between the end of the hose
and the drain. This gap is needed to prevent backflow
of sewer water into the water softener. Do not put the
end of the drain hose into the drain.

OCATION REQUIREMENTS
Consider all of the following when selecting an installa-
tion location for the water softener.
=Do not locate the water softener where freezing
temperatures occur. Do not attempt to treat water
over 49ºC. Freezing temperatures or hot water
damage voids the warranty.
=To condition all water in the home, install the water
softener close to the water supply inlet, and
upstream of all other plumbing connections, except
outside water pipes. Outside faucets should remain
on hard water to avoid wasting conditioned water
and salt.
=A nearby drain is needed to carry away regenera-
tion discharge (drain) 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.
=The water softener works on 28V DC electrical
power, supplied by a direct plug-in power supply
(included). Provide nearby a 120V, 60 Hz electrical
outlet in accordance with national and local codes.
=Always install the water softener between the water
inlet and water heater. Any other installed water
conditioning equipment should be installed between
the water inlet and water softener (See Figure 4
below).
=Avoid installing in direct sunlight. xcessive sun
heat may cause distortion or other damage to non-
metallic parts.

VA VE 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 com-
pression fitting (1/4 NPT x 1.25 cm minimum tube) and
1.25 cm tubing from your local hardware store. Plumb
a rigid drain as needed (See Figure 6).
NOTE: Avoid drain hose runs longer than 9 meters.
Avoid elevating the hose more than 2.5 meters
above the floor. Make the valve drain line as
short and direct as possible.
IN ET / OUT ET P UMBING OPTIONS
Always install either a single bypass valve (provided),
as shown in Figure 7, or, if desired, parts for a 3 valve
bypass system (not included) can be purchased and
assembled, as shown in Figure 8. Bypass valves
allow you to turn off water to the softener for mainte-
nance if needed, but still have water in house pipes.
Pipe fittings must be 1.9 cm minimum.
Use:
=Copper pipe
=Threaded pipe
=P X (Crosslinked Polyethylene) pipe
=CPVC plastic pipe
=Other pipe approved for use with potable water
IMPORTANT: Do not solder with plumbing attached to
installation adaptors and single bypass
valve. Soldering heat will damage the
adaptors and valve.

Installation Instructions
TYPICA INSTA ATION
TURN OFF WATER SUPP Y
1. Close the main water supply valve, located near the
well pump or water meter.
2. Shut off the electric or fuel supply to the water
heater.
3. Open all faucets to drain all water from house pipes.
NOTE: Be sure not to drain water from the water
heater, as damage to the water heater ele-
ments could result.
ASSEMB Y
1. coPure models are factory assembled. During
installation, unsnap and remove the top cover,
together with the salt lid, to expose the softener
valve assembly. Set them aside to prevent damage.
Check the brinewell to be sure it is secured and ver-
tical (See Figure 11).
2. Lift the brine valve out of the brinewell. Make sure
the float stem is parallel to the stand tube so the
seals will seat properly during operation. Place the
brine valve back into the bottom of the brinewell and
reinstall the brinewell cover.
3. Install the brine tank overflow grommet and elbow
into the 2 cm diameter hole in the back of the salt
storage tank wall.
MOVE THE UNIT INTO P ACE
1. Move the water softener into the desired location.
Set it on a solid, level surface.
IMPORTANT: Do not place shims directly under the
salt storage tank to level the softener.
The weight of the tank, when full of
water and salt, may cause the tank to
fracture at the shim.

2. Visually check and remove any debris from the
water softener valve inlet and outlet ports.
3. Make sure the turbine assembly spins freely in the
"out" port of the valve (See Figure 10).
4. If not already done, put a light coating of silicone
grease on the single bypass valve o-rings.
5. Push the single bypass valve into the softener valve
as far as it will go. Snap the two large holding clips
into place, from the top down as shown in Figures
12 & 13.
IMPORTANT: Be sure the clips snap firmly into place
so the single bypass valve will not pull
out.
COMP ETE IN ET AND OUT ET P UMBING
Measure, cut, and loosely assemble pipe and fittings
from the main water pipe to the inlet and outlet ports of
the water softener valve. Be sure to keep fittings fully
together, and pipes squared and straight.
Be sure hard water supply pipe goes to the water sof-
tener valve inlet side.
NOTE: Inlet and outlet are marked on the water sof-
tener valve. Trace the water flow direction to
be sure hard water is to inlet.
IMPORTANT: Be sure to fit, align and support all
plumbing to prevent putting stress on
the water softener valve inlet and outlet.
Undue stress from misaligned or unsup-
ported plumbing may cause damage to
the valve.
Complete the inlet and outlet plumbing for the type of
pipes you will be using.

10
CO D 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 8,
will maintain ground continuity. If you
use a plastic bypass valve at the unit,
continuity is broken. To restore the
ground, do the following:
1. Install a #4 copper wire across the removed section
of main water pipe, securely clamping it at both
ends (See Figure 14) - parts not included.
NOTE: Check local plumbing and electrical codes
for proper installation of the ground wire.
The installation must conform to them. In
Massachusetts, plumbing codes of
Massachusetts shall be conformed to.
Consult with your licensed plumber.
Installation Instructions
1. Measure, cut to needed length and connect the 9.5
mm drain line (provided) to the salt storage tank
overflow elbow and secure in place with a hose
clamp.
2Route the hose to the floor drain, or other suitable
drain point no higher than the drain fitting on the salt
storage tank (This is a gravity drain). If the tank
overfills with water, the excess water flows to the
drain point. Cut the drain line to the desired length
and route it neatly out of the way.
IMPORTANT: For proper operation of the water soften-
er, do not connect the water softener
valve drain tubing to the salt storage
tank overflow hose.
TEST FOR EAKS
To prevent air pressure in the water softener and
plumbing system, complete the following steps in order:
1. Fully open two or more softened cold water faucets
close to the water softener, located downstream from
the water softener.
2. Place the bypass valve (single or 3 valve) into the
"bypass" position. See Figures 7 & 8 on Page 7.
3. Slowly open the main water supply valve. Run
water until there is a steady flow from the opened
faucets, with no air bubbles.
4. Place bypass valve(s) in "service" or soft water posi-
tion as follows:
=Single bypass valve: Slowly move the valve stem
toward "service," pausing several times to allow
the water softener to fill with water.
=3 valve bypass: Fully close the bypass valve and
open the outlet valve. Slowly open the inlet valve,
pausing several times to allow the water softener
to fill with water.
5. After about three minutes, open a hot water faucet
until there is a steady flow and there are no air bub-
bles, then close this faucet.
6. Close all cold water faucets and check for leaks at
the plumbing connections that you made.
7. Check for leaks around clips at softener’s inlet and
outlet. If a leak occurs at a clip, depressurize the
plumbing (turn off the water supply and open
faucets) before removing clip. When removing clips
at the softener’s inlet or outlet, push the single
bypass valve body toward the softener (See Figure
15). Improper removal may damage clips. Do not
reinstall damaged clips.
INSTA SA T STORAGE TANK OVERF OW
HOSE
INSTA VA VE DRAIN HOSE
NOTE: See valve drain options on pages 6 & 7.
1. Measure, cut to needed length and connect the 9.5
mm drain line (provided) to the water softener valve
drain fitting. Use a hose clamp to hold the hose in
place.
IMPORTANT: If codes require a rigid drain line see
“Valve Drain requirements" section.
2. Run the drain hose (or a rigid line) to the floor drain.
Secure drain hose. This will prevent “whipping'' dur-
ing regenerations. Be sure to provide a 4 cm min-
imum air gap to prevent possible sewer water
backup. See “Air Gap Requirements" section.
NOTE: In addition to a floor drain, you can use a laun-
dry tub or standpipe as a good drain point for
this hose.. Avoid long drain hose runs, or ele-
vating the hose more than 2.5 meters above
the floor.

ADD WATER AND SA T TO THE SA T
STOR AGE TANK
1. Using a container, add about three gallons of clean
water into the salt storage tank.
2. Add salt to the storage tank. Use nugget, pellet or
coarse solar salts with less than 1% impurities.
P UG IN THE POWER SUPP Y
During installation, the water softener wiring may be
moved or jostled from place. Check to be sure all
leadwire connectors are secure on the back of the
electronic board and be sure all wiring is away from
the valve gear and motor area, which rotates during
regenerations.
1. Plug the water softener’s power supply into an elec-
trical outlet that is not controlled by a switch and is
approved by local codes.
NOTE: The water heater is filled with hard water and,
as hot water is used, it will refill with condi-
tioned water. In a few days, the hot water will
be fully conditioned. To have fully conditioned
hot water immediately, wait until the initial
recharge is over. Then, drain the water heater
(following instructions for water heater) until
water runs cold.
PROGRAM THE CONTRO ER
1. Install the softener’s top cover and salt lid.
2. Complete the programming steps on:
Pages 12 & 13 for Model P100, or
Pages 15 & 16 for Model P200.
SANITIZE THE WATER SOFTENER /
SANITIZE AFTER SERVICE
Care is taken at the factory to keep your unit clean and
sanitary. Materials used to make the unit will not infect
or contaminate your water supply, and will not cause
bacteria to form or grow. However, during shipping,
storage, installation and operation, bacteria could get
into the unit. For this reason, sanitizing as follows is
suggested* when installing.
1. Slide open the salt lid, remove the brinewell cover
and pour about 90 ml (6 tablespoons) of household
bleach into the softener brinewell. Replace the
brinewell cover.
2Make sure the bypass valve(s) is in the “service”
(open) position.
3 Start a recharge: Press the R CHARG button and
hold for 3 seconds, until “Recharge Now” begins to
flash in the display. This recharge draws the sanitiz-
ing bleach into and through the water softener. Any
air remaining in the unit is purged to the drain.
4. After the recharge has completed, fully open a cold
water faucet, downstream from the softener, and
allow 190 liters of water to pass through the system.
This should take at least 20 minutes. Close the
faucet.
*Recommended by the Water Quality Association. On some
water supplies, the unit may need periodic disinfecting.
RESTART THE WATER HEATER
1. Turn on the electricity or fuel supply to the water
heater and relight the pilot, if applicable.
NOTE: The water heater is filled with hard water and,
as hot water is used, it refills with conditioned
water. In a few days, the hot water will be fully
conditioned. To have fully conditioned hot
water immediately, wait until the initial recharge
(previous step) is over. Then, drain the water
heater (following instructions for water heater)
until water runs cold.

POWER OUTAGE MEMORY
If electrical power to the water softener is lost, “mem-
ory'' built into the timer circuitry will keep all settings
for several hours. While the power is out, the display
is blank and the water softener will not regenerate.
When electrical power is restored, the following will
occur.
You have to reset the present time only if the display
is flashing. The HARDN SS and R CHARG TIM
never require resetting unless a change is desired.
ven if the clock is incorrect after a long power out-
age, the softener operates as it should to keep your
water soft. However, regenerations may occur at the
wrong time of day until you reset the clock to the cor-
rect time of day.
NOTE: If the water softener was regenerating when
power was lost, it will now finish the cycle.

Features / Options
(All Models)
ADDING SA T
Lift the salt lid and check the salt storage level fre-
quently. If the water softener uses all the salt before
you refill it, you will experience hard water. Until you
have established a refilling routine, check the salt
every two or three weeks. Always add if less than 1/4
full. Be sure the brinewell cover is on.
NOTE: In humid areas, it is best to keep the salt stor-
age level lower, and to refill more often to avoid
salt “bridging”.
Recommended Salt: Nugget, pellet or coarse solar
salts with less than 1% impurities.
Salt Not Recommended: Rock salt, high in impurities,
block, granulated, table, ice melting, ice cream making
salts, etc.
BREAKING A SA T BRIDGE
Sometimes, a hard crust or salt “bridge” forms in the
brine tank. It is usually caused by high humidity or the
wrong kind of salt. When the salt “bridges,” an empty
space forms between the water and the salt. Then,
salt will not dissolve in the water to make brine.
Without brine, the resin bed is not recharged and hard
water will result.
If the storage tank is full of salt, it is difficult to tell if
you have a salt bridge. A bridge may be underneath
loose salt. Take a broom handle, or like tool, and hold
it next to the water softener. Measure the distance
from the floor to the rim of the water softener. Then,
gently push the broom handle straight down into the
salt. If a hard object is felt before the pencil mark is
even with the top, it is most likely a salt bridge. Gently
push into the bridge in several places to break it. Do
not use any sharp or pointed objects as you may
puncture the brine tank. Do not try to break the salt
bridge by pounding on the outside of the salt tank.
You may damage the tank.

C EANING THE NOZZ E & VENTURI
A clean nozzle & venturi (See Figure 42) is a necessity
for the water softener to work properly. This small
component creates the suction to move brine from the
brine tank, into the resin tank. If it should become
plugged with sand, silt, dirt, etc., the water softener will
not work, and hard water will result.
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.
To get access to the nozzle & venturi, remove the
water softener’s top cover. Put the bypass valve(s)
into the bypass position. Be sure the water softener is
in soft water (service) cycle (no water pressure at noz-
zle & venturi). Then, holding the nozzle & venturi
housing with one hand, un screw 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(s). 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 & ven-
turi.
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 (soft
water) position.
Recharge the softener to reduce water level in the
tank. This will also assure that the softener is com-
pletely recharged and ready to provide softened water
again. Check the water level in the tank by looking
down the brinewell. If the water level does not drop
after a recharge, the problem has not been resolved.
Call 1-800-693-1138, Monday - Friday, 7 am to 6 pm,
CST.
PROTECT THE WATER SOFTENER FROM
FREEZING
If the softener is installed where it could freeze (sum-
mer cottage, lake home, etc.), you must drain all water
from it to stop possible freeze damage. To drain the
softener:
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 soft water pipes to vent pres-
sure in the softener.
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 power supply at the wall outlet. Slide
open the salt lid and remove the softener’s top
cover. Take off both drain hoses if they will interfere
with moving the softener into position over the drain.
5. Carefully remove the large holding clips at the sof-
tener inlet and outlet. Separate the softener from
the plastic installation adaptors, or from the bypass
valve.
6. Lay a piece of 5 cm thick board near the floor drain
(See Figure 43).
7. Move the softener 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. Do not
allow the softener’s weight to rest on the inlet and
outlet fittings or they may break.
8. Tip the bottom of the softener up a few centimeters
and hold until all water has drained. Leave the sof-
tener laying like this until you are ready to use it.
Plug the inlet and outlet with clean rags to keep dirt,
bugs, etc. out.
