Specifications & Performance Claims
This model is efficiency rated. The efficiency rating is valid only at the minimum salt dose. This system has 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.
This water treatment system has 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 its listed rating or be operated at a
sustained maximum service flow rate greater than its listed rating. This system has 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 laboratory 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.
While testing was performed under standard laboratory conditions, actual performance of the system may vary based
on local water conditions. This system has been tested according to NSF/ANSI Standard 42 for the reduction of chlorine
taste and odor. The concentration of the indicated substance in water entering the system was reduced to a concentration less than or equal to the permissible limit for water leaving the system, as specified in NSF/ANSI Standard 42.

Safety Guides
= The water softener requires a minimum water flow of 3 gallons per minute 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 necessary (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 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 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.
European Directive 2002/96/EC requires all electrical and electronic equipment to be disposed of accord-
ing 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.
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.
In the state of California: You must turn the Salt Efficiency Feature setting to ON. This may initiate
more frequent recharges. However, it will operate at 4,000 grains per pound of salt or higher. To turn
on the Salt Efficiency Feature, follow the instructions in the “Salt Efficiency” section of this manual.

Water Conditioning Information
IRON
Iron in water can cause stains on clothing and plumbing 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 filtration. Chlorination is also recommended for bacterial
iron.
Colloidal and inorganically bound iron is of ferric or ferrous 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 sediment. This material is most often clay or silt. Extreme
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.

Installation Requirements
LOCATION REQUIREMENTS
Consider all of the following when selecting an installation location for the water softener.
Do not locate the water softener where freezing
=
temperatures occur. Do not attempt to treat water
over 120ºF. 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 24V DC electrical
power, supplied by a direct plug-in power supply
(included). Provide nearby a 120V, 60 Hz electrical
outlet in accordance with NEC 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. Excessive sun
heat may cause distortion or other damage to nonmetallic parts.
PLUMBING CODES
All plumbing must be completed in accordance with
national, state and local plumbing codes.
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 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 1-1/2” 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.

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 (1/4 NPT x 1/2 in. minimum tube) and
1/2" tubing from your local hardware store. Plumb a
rigid drain as needed (See Figure 6).
NOTE: Avoid drain hose runs longer than 30 feet.
Avoid elevating the hose more than 8 feet
above the floor. Make the valve drain line as
short and direct as possible.

INLET / OUTLET PLUMBING 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 maintenance if needed, but still have water in house pipes.
Pipe fittings must be 3/4” minimum.
Use:
= Copper pipe
= Threaded pipe
= PEX (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
