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 ED2000 will not show any change in the water hardness as
per the traditional methods. The e ects of 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.
Water Hardness Level Calcium Carbonate Equivalent (PPM)
Soft Less than 17.1
Slightly Hard 17.1 to 60
Moderately Hard 60 to 120
Hard 120 to 180
Very Hard 180 and above
05
Calcium Carbonate Equivalent (GPG)
Less than 1.0
1.0 to 3.5
3.5 to 7.0
7.0 to 10.5
10.5 and above
Observation Timetable
The following timetable can be observed for the performance evaluation of ED2000 for the
rst 90 days:
Day 1:
You may notice that the soap foams more e ciently on the rst day you install the device, as
ED2000 immediately reduces scale buildup in hot and cold water systems.
After 1 week:
The device breaks 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.
However, most dissolved particles will be microscopic and invisible 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: ED2000 is NOT a water softener and DOES NOT remove calcium or
magnesium from the water.
