Product Specifications
This model is efficiency rated. The efficiency rating is valid only at the minimum salt dose. This
softener 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 its
operation.
This softener 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 softener 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.

Safety Guides
Follow the installation instructions carefully. (Failure to install the unit 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 fed-
eral codes.
Use care when handling the unit. Do not turn upside down, drop, or set on sharp protrusions.
Do not locate the unit where freezing temperatures occur. Do not attempt to treat 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 unit requires a minimum water flow of 3 gallons per minute at the inlet. Maximum allowable
inlet water pressure is 100 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.)
The unit works on 24 volt-60 hz electrical power only. Be sure to use the included transformer
and plug it into a nominal 120V, 60 cycle household outlet that is grounded and properly protected by an overcurrent device such as a circuit breaker or fuse. If transformer is replaced, use only
the authorized service, Class II, 24V 10VA transformer.
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. For California installations the Salt Efficiency setting must be set to “ON”.
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 province and local laws for proper disposal of this equipment.
Water Conditioning Information
Water conditioning is the treatment of four general conditions. These are:
1. HARDNESS
2. IRON
3. ACIDITY
4. SEDIMENTS
1. HARDNESS is a term to describe the presence of calcium and magnesium minerals in water. A
chemical analysis accurately measures the amount of minerals in grain weight. For example,
one gallon of water with 5 grains per gallon (gpg) hardness has dissolved minerals, that if solidified, about equals the size of one ordinary aspirin tablet. One gallon of water, 25 gpg hard, has
a mineral content equal in size to 5 aspirin tablets. Water hardness varies greatly across the
country. It generally contains from 3 to 100 gpg.
Hard water affects living in general. Hardness minerals combine with soap to make a soap curd.
The curd greatly reduces the cleaning action of soap. Precipitated hardness minerals form a
6
Miracle Water Installation & Operation Manual
crust on cooking utensils, appliances, and plumbing fixtures. Even the tastes of foods are affected. A water softener removes the hardness minerals to eliminate these problems, and others.
Sodium Information: Water softeners using sodium chloride (salt) for regeneration and add
sodium to the water. Persons on sodium restricted diets should consider the added sodium as
part of their overall intake.
2. 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:
1 Ferrous (clear water),
2 Ferric (red water),
3 Bacterial and organically bound iron,
4 Colloidal and inorganically bound iron (ferrous or ferric).
*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.
1 Ferrous (clear water) iron is soluble and dissolves in water. It 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. This unit will reduce moderate amounts of this
type of iron (see specifications).
When using the softener to remove Ferrous (clear water) iron, add 5 grains to the hardness setting for every 1 ppm of Ferrous (clear water) iron.
2 Ferric (red water), and 3 Bacterial and organically bound irons are insoluble. This iron is vis-
ible 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. This unit
will not reduce ferric or bacterial iron.
4 Colloidal and inorganically bound iron is of ferric or ferrous form that will not filter or exchange
out of water. In some instances, treatment may improve colloidal iron water, but always CONSULT A QUALIFIED WATER CHEMISTRY LAB before attempting to treat it. 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.
Iron in water causes stains on clothing and plumbing fixtures. It negatively affects the taste of
food, drinking water, and other beverages. This unit will not reduce colloidal iron.
3. ACIDITY or acid water is caused by carbon dioxide, hydrogen sulfide, and sometimes industri-
al wastes. It is corrosive to plumbing, plumbing fixtures, water heaters, and other water using
appliances. In can also damage and cause premature failure of seals, diaphragms, etc., in water
handling equipment.
A chemical analysis is needed to measure the degree of acidity in water. This is called the pH
of water. Water testing below 6.9 pH is acidic. The lower the pH reading, the greater the acidity. A neutralizer filter or a chemical feed pump are usually recommended to treat acid water.
4. SEDIMENT is fine, foreign material particles suspended in water. This material is most often clay
or silt. Extreme amounts of sediment may give the water a cloudy appearance. A sediment fil-
ter installed ahead of the water softener normally corrects this situation.

Assembly
1. Miracle Water models are factory assembled. During installation, remove the Salt Hole Cover.
Set aside to prevent damage. Check the brinewell to be sure it is secured and vertical (see
Figure 1). Slide Faceplate Cover forward to expose back valve assembly.
2. Lift the brine valve out of the brinewell. Be sure the float stem is parallel to stand tube so seals
will seat properly during operation. Replace the brine valve in the brinewell bottom and install
the Brinewell Cover.
3. Install the brine tank overflow grommet and elbow in the 13/16” diameter hole in the back of the
salt storage tank sidewall.

Planning Installation
Inlet - Outlet Plumbing Options
• ALWAYS INSTALL either a single bypass valve (included) or a 3 valve bypass system (not
included). Bypass valves allow you to turn off water to the softener for repairs if needed, but still
have water in house pipes.
• Use 3/4” (minimum) pipe and fittings.
• Use sweat copper... or, threaded pipe... or, PVC plastic pipe... or, other approved plumbing.
