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 local 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 49_C. 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 11 litres per minute at the inlet. Maximum allowable inlet water
pressure is 8.6 bar. If daytime pressure is over 5.5 bar, 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- -50 hz electrical power only. Be sure to use the included 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.

Water Conditioning
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 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.
! 1 gpg = 0.959 _d = 1.71 _F
@ 1 gallon = 3.78 litres.
Sodium Information: Water softeners using sodium chloride (salt) for regeneration add sodium to the water.
Persons on sodium restricted diets should consider the added sodium as part of their overall intake.
