2. ABOUT THE EQUIPMENT
2.1
HOW DOES IT WORK?
The cationic resins in the softener’s tank transform calcium carbonate in
sodium carbonate, which is water-soluble at the working temperatures of both
coffee makers and ice makers machines.
The transfer of sodium ions between the resins and water is imperative to
soften drinking water, but this process tends to decline in proportion to the
flow rate and the consumption of water. For this reason, it is necessary to
regenerate the exhausted resins by making water and salt flow through them,
therefore returning them to their active state.
The resins gradually lose their cationic function, and consequently their
efficiency, with each regeneration. We recommend replacing them after seven
years of use.

3. INSTALLATION
3.1
PACKAGING
Before the installation, check that the equipment was not damaged by the
transport and does not show any anomaly. If in doubt, ask your seller, whose
information is written on the back of this manual.
Don’t throw the package away for some time, being careful to keep any
dangerous or small parts of the package away from children.
3.2
CHOOSING THE PLACE OF INSTALLATION
Ensure that any other water treatment machine is not present upline of the
place of installation.
Ensure that feed water comes from a drinking water pipe. We recommend
checking the chemical and physical parameters of the drinking water as well as
its hardness before installation.
Install the equipment near a floor sink, to dispose of the waste water produced
by the regeneration.
Install the equipment in a dry place that can be easily accessible to maintain,
regenerate and clean the equipment. Do not install the equipment in dirty and
unhygienic places, or in any place difficult to clean.
Ensure that room temperature in the place of installation is between 4°C and
35°C.
Keep away from corrosive or acid products.
Do not install in places where electric safety norms or personal safety norms
are openly disregarded.
Hydric pressure must not be under 0.1 Mpa (1 bar) or over 0.8 Mpa (8 bar).
(We recommend at least 3 or 4 bar)
If hydric pressure is over 8 bar, it is necessary to install a pressure adaptor.
Salt packages or boxes must not be kept in humid places or in direct contact
with the floor: keep it, for example, on a wooden pallet.
