The machine must be installed with an ionic resin water softener.
The water softener may be of different types, with different resin capacities and different
periods of validity.
The resins are regenerated by adding coarse kitchen salt or salt pastilles to the water sof-
tener.
If the regeneration of the resins is not made at the due dates,calcareous deposits will form
which progressively decrease the machine’s efficiency until its functions are completely
blocked.
The regeneration due dates and method thereof may be found in the instructions provided
with the equipment.
If regeneration is performed at the due dates, the machine is maintained in ideal working
conditions.

A water filter should be installedin thewater supply pipe. This filtersystem reduces great-
ly the amount of scaling in the machine and has a decisive effect on the quality of the wa-
ter. It is therefore of immense importance for the quality of the coffee and the safe
operation of the machine.

Before connectingthe machine, makesure the available electricity and watersuppliescor-
respond to the specifications on the data plate.
The espresso coffee machine should be placed on a stable flat surface with the bodywork
at a minimum distance of 20 mm from the supporting surface. It is importanat to find a
perfectly horizontal position of the machine on it’s support so that coffee will be equally
ditributed in all cups (use the adjustable feet). The (electricity and water) supply connec-
tions and a water outlet fitted with a siphon should be close to the machine. A support sur-
face should also be available for accessories (grinder/doser, etc.)
To ensure correct operation and safety, the coffee machine should not be exposed to out-
door weather conditions (rain, sun, ice).
Do not install in rooms (kitchens) cleaned using water jets.
The electrical safety of this machine is guaranteed only if it is correctly connected to an
effective earthing installation as required by the safety regulations in force. This essential
safety requirement should be checked and, if there are any doubts, a complete check of
the installation should be carried out by qualified personnel. The maker cannot be held
responsible for any damage caused by failure to earth the machine.
If the machine is stored on premises where the temperature may drop below freezing
point, always empty the boiler and the water circulation pipes.
