PRIMARY BENEFIT
YARNA reduces scalling
on surface
YARNA modifies the
crystallization of calcium. The
limescale loses its adhesive
power and is washed away with
the water as a fine powder.
YARNA sanitizes
the piping system
YARNA carefully dissolves
existing limescale built-up in
the pipe. Only a thin protective
layer remains in the pipe.
YARNA prevents rust
and corrosion
YARNA creates a electrophoresis
process, which produces a
protective metal-carbonate layer.
It acts as prevention of rust
and corrosion.
The reduction of scale = the reduction of rust
As soon as limescale deposits have built up, iron particles imbed into it. Thus, the limescale
and the rust blend into one material that are seen as red-colored deposits in the pipe. When
the YARNA treatment dismantles the scale, it simultaneously reduces also rust with it.
Clearing out the deposits is a gentle process where limescale is brought back into solution
and washed out in the water as: calcium, magnesium and iron. It is absolutely save to drink
as these are all healthy minerals.
The reduction of scale = the reduction of bacteria
We know that limescale acts as a breeding ground for bacteria and other unwanted substances.
As soon as YARNA is installed and the scale is reduced, the bacteria breeding ground is also
reduced. This way, bacterial contamination is greatly reduced or even fully removed.

Around 1/4" of limescale will build up in an
average household over 4 years and can
cause up to a 40 % reduction in your
home’s energy efficiency. You spend more
money for less effective heat.
Eventually, untreated hard water can
cause appliances to leak, malfunction and
use more energy. Also the heating
elements of water heaters are highly
susceptible to damage from limescale.
Limescale collects inside the iron and
stains clothes. Some stains cannot be
removed even if washed again. Yarna
ensures this will never happen.
Ruined finishes, damaged washers and
seals, valve blockages. Pipes may clog up
or leak.
Faucets need to be replaced 40% sooner.

Hard water can have a significant effect on
your hair and skin. The minerals present in
hard water can make it difficult to achieve
a thorough rinse , causing residual buildup
on your hair. The result is dry, dull, tangly
and strange colored hair.
Hard water can dry your skin. Minerals
drying on your skin can clog pores and
cause flaking an itching. Cosmetics and
moisturizing lotions are less effective.
As soon as scale deposits have built up,
iron particles embed into it. Thus, the
scale and the rust blend into one material
that are seen as red-colored deposits in
the pipe.
Scale acts as a breeding ground for
bacteria and other unwanted substances.
With YARNA the bacteria breeding
ground disappears. This way, bacterial
contamination is greatly reduced or even
fully removed.

KNOW THIS BEFORE INSTALLING INSTRUCTIONS

You need a minimum of 10” (25cm) of exposed pipe.
For optimal water treatment, YARNA is best installed near
the water meter or at the main water supply. Make sure you
have access to a power outlet. Our power adapter has 5ft
(1.5m) of cable.
Different installation positions are possible. You can install
the main unit vertically, horizontally or at any other angle.
Please observe different placement examples, shown in the
images to the right. Leave a minimum safe distance of at
least ½" (1 cm) between the two impulse bands.
The main unit can be installed on the wall or directly to the
pipe. To secure it to the wall use the screws and anchors
provided in the box. To mount it on the pipe run the zip ties
through the top and bottom holes of each side of the main unit.
The position of the main unit relative to the pipe is not
important. You may also install the unit over the impulse bands.
Each impulse band has a total length of 59“ (150cm). For
limited pipe space you need to wind at least 9 turns for each
band for the product to be effective. For unlimited pipe
space it is recommended to wrap as much of the impulse
bands as possible.
In case of limited space, the windings can be placed partly on
the main pipe and partly on the distributor pipe. All these
different installations are possible because the treatment
impulses extend over several meters to either side of the pipes.
The unit is effective up to 1.2 miles from the installation point
along with your pipe system. Depending on ambient
temperatures this effect can last up to 7 days after water exits
your pipe system. Minerals remain in the water as ions. This
prevents the lime-scale to stick to your skin or solid surfaces.

Min 1/2” (1cm)
Between Bands
Secure the main unit either to the wall by using the screws inside or
directly onto the pipe using the plastic zip ties.
Wind the impulse band around the pipe producing a coil. Make sure
you wind the band tightly to the pipe and place the windings close to
each other. Latch the end of the impulse band to the pipe using another
zip tie. Now repeat steps 2 and 3 with the second impulse band.

Use a zip tie to secure the impulse band to the pipe.

Time to power up the unit. First plug the power adaptor to the main unit, and
then connect the power supply to an electrical outlet. The power adapter
has a LED light that must be visible. The main unit has two white diagnostic
lights that will come on, showing that both impulse bands are operating
normally. Your YARNA water softener works from now on maintenance-free.

WHY DESCALING IS BETTER THAN SOFTENING:
Yarna does NOT eliminate wanted minerals like Calcium and Magnesium. Minerals are
good and a necessary part of our diet. Yarna does NOT use salt or waste any water. Water
descaling is a process used to reduce the negative effects of hard water. It prevents the
minerals from forming scale deposits, which is the main disadvantage of hard water.
Your YARNA water softener WILL NOT make your water potable.
Your YARNA water softener is suitable for all pipe materials: iron, copper, plastic,
stainless steel, PVC, compound pipes, PE-X, etc.
Protect the electronic unit and the power supply against direct water. The unit is IP65
rated (protected against jets of water)
WHAT TO EXPECT & IMPORTANT NOTES
Yarna CWD30 is a physical water treatment system. It treats the water with electric
impulses which are generated in the electronic unit and are controlled by a
computerized micro-chip. The signal-frequencies are transmitted via the impulse coils
that are wrapped around the pipe. The bands interact as pairs and form a
frequency-field that changes the crystals in the water as it flows by. Thus, the limescale
particles lose their adhesive power.
If you have a home or small business that uses water, the Yarna will help protect
against : Blocked piping systems, Dull surfaces and malfunctioning machinery, High
costs for heating, High expenses for cleaning, Rust accumulation in the pipe that leads
to corrosion, Bacterial growth in drinking water carrying pipes, and Others.
Depending on the condition of your plumbing (how large the limescale deposits are),
it might take up to three months to notice best results.
