6. Installation Instructions
6.1. General advices
Caution! The installation must be performed by a
professional installer only.
Caution! It is seriously recommended to install a pres-
sure reducer ahead of the softener, if the input pres-
sure is more than 6 bar. Failing to adhere to this safety
note can cause irreversible damage.
Location
When you choose the softener location, please take into
account the following parameters:
• Install the KS20S softener in a chosen place on a flat firm
and clean surface.
• The KS20S softener must be close to a drain line to allow
an easy connection.
• Make sure there is an electrical earth grounded plug to
power the unit.
Caution! During cold weather, bring the softener to
room temperature before operation.
Caution! During hot weather, do not install the softener
in direct sunlight or in a room with a temperature
above 45°C.
Pressure
A minimum pressure of 2 bar is needed to allow the valve to
regenerate properly. Please do not operate over 8 bars.
If this is the case, use a pressure reducer upstream of the
installation.
Power connection
Be sure that power cannot be switched off accidentally at
a wall switch. If the power cable is damaged, please ask a
professional electrician to change it.
Warning! All electrical and plumbing installations
should be performed by professional electricians and
installers in accordance with all local codes.
Plumbing
The plumbing must be in good state. In case of doubt, please
change it. We advise the use of prefilter upstream the instal-
lation.
All plumbing for the water inlet, distribution and drain lines
should be done correctly in accordance with the legislation in
force at the time of the installation. The pipe size for the drain
line should be a minimum of 20 mm (3/4'').
Caution! Finish all the soldering on the main plumbing
and on the drain, before connecting the softener.
Failing to adhere to this safety note can cause irrever-
sible damage to the KS20S.

near vicinity to the softener before mounting.
Failing to adhere to this saftey note can cause irrever-
sible damage.
