system, please contact your local RainSoft Dealer. Your local RainSoft Dealer is familiar with
your particular water conditions, and is able to address your concerns promptly and efficiently.

INFORMATION ON WATER TREATMENT SYSTEMS

There are many misconceptions that have been developed about water treatment systems.
The most common topic of confusion is the amount of sodium (Na), not table salt (NaCl), that is
added to the water from a water conditioner. In reality, ion exchange does replace the hardness
ions in your water with sodium ions, but the common misconception is the amount used.
For every one (1) grain of hardness, the exchange process will deliver approximately eight (8)
milligrams of sodium per one (1) liter of water. The amount of sodium present in a standard
eight (8) ounce glass of treated water, that was 10 grains hard prior to treatment, would be
around 19 milligrams of sodium. This is an insignificant amount of sodium considering a
typical slice of white bread has about 140 milligrams.
Another common misconception that needs mentioning is the amount of salt used by the
conditioner to regenerate the system. In the past, water conditioners used more salt to
regenerate, but that was due to old technology and standards. Water conditioners do use
salt for regeneration, but the amount of salt varies by water consumption and hardness
levels. Fortunately, today' s technology allows us to dispense just the right amount of salt for
maximum efficiency, based on your individual water consumption needs.

APPLICATION LIMITATIONS

On hardness levels of 60 grains and higher, the system may not achieve a hardness of less
than one (1) grain; due to high Total Dissolved Solids, some bleed through is possible. Bleed
through can also be caused by sodium levels higher than 1,000 parts per million. In either
case, your system can be programmed to minimize these effects. See your RainSoft Dealer
for details.
Chlorine or Chloramine levels on municipality treated water should not exceed four (4) parts
per million.* When Chlorine or Chloramine levels are four (4) parts per million* or greater, it
can have adverse effects on your system. In applications where high levels are a concern,
pre‑filtration is necessary to reduce the Chlorine or Chloramine to an acceptable level. See
your RainSoft Dealer for details.
When this system is installed on water with Ferrous iron, also known as clear water iron,
the maximum range of removal is based on local water conditions. The range is generally
two (2) to 10 parts per million. Your equipment may require special programming, along with
an additive to the brine tank, to maximize the equipment' s ability to remove iron. See your
RainSoft Dealer for details.
* Maximum disinfectant level of Chlorine or Chloramine recommended from the EPA.

OPERATIONAL SPECIFICATIONS

Water Pressure:
Operating Temperatures:
Electrical Requirements
A properly grounded alternating current supply (110 VAC 60 Hz or 230 VAC 50 Hz) is
required for the operation of this system. Please check the power supply for the
correct voltage requirements.
Bypass Valve
The bypass valve enables you to bypass the system in situations of emergency leaks in the
equipment, service calls.
3/4 inch to 1 1/4 inch I.D.
1/2 inch I.D.
20 psi – 120 psi (1.38 bar – 6.89 bar)
40 – 100°F (4.4 – 37.8°C)
Helpful Tip: Another common
misconception of water treatment
systems is the idea that soft water will
produce clear ice cubes. Cloudy or white,
hazy ice cubes are caused by air that is
slowly being released from the water
during the freezing process, which has
nothing to do with the performance of
your system.
Important Note: This system may be
installed on well water or municipality
treated water supplies.
Important Note: Most municipality
treated water supplies contain chlorine
as a disinfectant. Many municipalities
also inject ammonia into the water supply,
creating chloramine.
Important Note: Iron fouled resin is not
eligible for warranty replacement.
The Amount of Iron reduced by your
conditioner is based on the incoming
pH. Consult your local RainSoft Dealer
for more information.
Important Note: This system requires
the use of the included power supply
(24 VDC).
Important Note: The manually operated
bypass valve enables the conditioner
to be isolated from the water service
line for maintenance and service. It
also maintains the continuity of the
water supply when the conditioner is
disconnected.
