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 ( .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.

Safety Guides
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.
=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 C 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.
=o 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 irective 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 prop-
er disposal of this equipment.
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 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. 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 laboratory 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.
