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.

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.
