Ispring ED2000 Bedienungsanleitung Seite 5

"Originally, water hardness was understood to measure water's capacity to precipitate soap.
Soap is precipitated chie y by the calcium and magnesium ions present. Other polyvalent
cations may also precipitate soap, but they often are in complex forms, frequently with
organic constituents, and their role in water hardness may be minimal and di cult to de ne.
In conformity with current practice, total hardness is de ned as the sum of the calcium and
magnesium concentrations expressed as calcium carbonate in milligrams per liter. "
The water hardness is determined by the concentration of magnesium and calcium in the
water. A traditional water softener eliminates the magnesium and calcium from the water
using an "Ion Exchange" process. Water treated with traditional softeners will demonstrate a
change in hardness as per the present practice of computing water hardness. ED2000 does
not remove any calcium or magnesium ions from the water; therefore, testing the water
before and after the installation of the ED2000 will not show any change in the water
hardness as per the traditional methods. The e ects of the ED2000 can be determined by
observing the changes in the treated water on scale-forming areas such as showerhead
scaling, humidi er media pad scaling, scaling on cooking utensils, and the quantity of soap
needed for the laundry.
The table below de nes water hardness according to the Water Quality Association. Once you
receive the water test results, you can use this table as a reference to determine the hardness
of your water.
ED2000 works e ectively on water with a hardness level of 425 ppm or 25 gpg. For harness
levels above 425 ppm, it is recommended to use the ED2000 in conjunction with a traditional
water softener to remove hardness and condition the water. This will minimize the salt
required to eliminate the hardness and sustain the cost-saving bene ts of the ED2000
water-conditioning system.

Observation Timetable
Below is a timetable that outlines the performance of the ED2000 during the rst 90 days of
use.
Day 1:
On day 1, you may notice that the soap lathers more easily and e ectively. This is because the
ED2000 immediately reduces existing scale buildup in the hot and cold water systems.
After 1 week:
The ED2000 begins breaking down scale deposits in water pipes, heating elements (such as
immersion rod heaters), and tanks. You may notice small particles in the water from the hot
water tap, but most broken-down particles will be microscopic and not visible to the naked
eye.
After 2 weeks:
You may start to observe scale loosening from showerheads, faucets, and kettles. Cleaning
plastic, ceramic, metal, and glass surfaces will become easier. You will also need less soap and
detergent for bathing, cleaning, and laundry.
After 1 month:
As the scale loosens from the water heating system, the time required to heat water will
decrease. You should see a signi cant reduction in scale buildup on pipes, faucets, and
showerheads.
After 3 months:
Scale buildup should stop developing and disappear from showerheads. The scaly crust in
toilets will be noticeably reduced. Depending on how long the scale has been building up
and the water hardness level, it may take up to 12 weeks for the full e ects to appear.
Please note: The ED2000 is NOT a water softener and DOES NOT remove calcium or
magnesium from the water.
