SYSTEM SPECIFICATIONS & DIMENSIONS
*
Note:
Install pressure regulator and water hammer arrestor if pressure exceeds rated pressure at any time.
The manufacturer reserves the right to make product improvements which may deviate from the specifications and descriptions stated herein, without
obligation to change previously manufactured products or to note the change.
These softeners conform to NSF/ANSI 44 for the specific performance claims as verified and substantiated by test data. These models are efficiency
rated. The efficiency rating is valid only at the stated salt dose and maximum service flow rate. They have a demand initiated regeneration (D.I.R.)
feature that complies with specific performance specifications in-tended to minimize the amount of regenerant brine and water used in their
operation. These softeners have a rated softener efficiency of not less than 3350 grains of total hardness exchange per pound of salt (based on sodium
chloride) and shall not deliver more salt than their listed ratings. The rated salt efficiency is measured by laboratory tests described in NSF/ANSI
Standard 44. These tests represent the maximum possible efficiency that the systems can achieve. Operational efficiency is the actual efficiency after
the system has been installed. It is typically less than the efficiency due to individual application factors including water hardness, water usage, and
other contaminants that reduce the softener’s capacity.
Feed Water Quality:
Iron < 0.5 PPM; Manganese < 0.05 PPM ; Turbidity < 1 NTU ; Free Chlorine < 0.5 PPM ; Hydrogen Sulphide – Nil ; Organics – Nil.
If feed water quality exceeds above limits, please call Rainfresh for advice on additional treatment that may be necessary.
B.
HOW YOUR WATER CONDITIONER WORKS
Your Rainfresh Softener removes hardness using a process called Ion Exchange. In this process, when hard water flows
through the unit, hardness-causing minerals such as Calcium & Magnesium, are trapped by the media (called
Resin
) and an
equivalent amount of sodium ions are released into the water. When the capacity of the resin to trap hardness minerals is
exhausted, the unit is re-charged by softener salt in an
automatic process
called
Regeneration
. During regeneration, the
unit first backwashes to remove any sediment, rust or other particulates, that may have accumulated in the unit. This is
followed by introduction of a saturated salt solution (
brine
) that bumps off the trapped hardness to drain and recharges the
resin with sodium. It then goes through a final rinse & refills the salt tank with water for the next regeneration.
Once you program the unit at the time of installation, the regeneration process happens automatically. All you need to do is
to ensure that there is always enough salt in the salt tank. The unit automatically calculates when to regenerate based on
your water hardness and use.
C.
SAFETY PRECAUTIONS AND CAUTIONS BEFORE INSTALLATION
Follow all applicable province/state and local regulations.
Handle your water softener carefully. Do not lie on side, turn upside down, drop or drag.
This unit requires softener salt (sodium chloride) to regenerate. Softener salt is available at most retailers. Persons
on sodium restricted diets should consider the added sodium as part of their overall intake. Potassium chloride can
be used as an alternate in such situations. Please consult Rainfresh technical support.
Install a pressure regulator and water hammer arrestor if pressure exceeds maximum rating at any time.
Note:
If
daytime pressure is over 80 psi, night time pressure may exceed maximum pressure rating.
Do not install on water that is microbiologically unsafe without adequate disinfection before or after the unit. For
effective disinfection install a Rainfresh Drinking Water System or Rainfresh UV disinfection system.
For use on cold water only.
