4.1. - Previous warnings.
The softening systems D-DF and D-UF series ARE NOT WATER PURIFYING SYSTEMS, there only
purpose is to remove hardness.
If the water supply does not come from public supply network or is from an unknown origin,
performing a physical-chemical and bacteriological analysis will be necessary to ensure the proper functioning
of the water softener equipment, please contact your dealer so they can advise you in these circumstances.
The water supply must be suitably filtered, so installing sediment prefilter to facilitate the removal of
suspended particles in order to protect internal parts of the valve affecting its operation is recommended.

The adequate place where you choose to put the system must have easy access to access the
system and also to fill up the salt tank.
The system must be placed on a flat surface, protected from direct sunlight, rain and
humidity.
The system (including the overflow and drain lines) must be placed where the temperature is
not below 1ºC or above 49ºC.
The system mustn’t be installed near acid nor vapours, or be exposed to products derived
from petroleum, to avoid the risks of deflagration and explosion.
