Suggestions on how to
obtain a good cup of coffee
To obtain high-quality coffee, it is important for
the hardness of the water used to not exceed 4-5
°f (French degrees). If the water hardness exceeds
these values, it is advisable to use a water softener.
Avoid using a water softener if the water hardness
is less than 4 °f.
If the taste of chlorine in the water is particularly
strong, a special filter should be installed.
It is not advisable to keep large supplies of coffee
beans. Never grind large amounts of coffee. Use the
amount the doser holds and, if possible, use it by
the end of the day. Never purchase ground coffee,
as it expires quickly.
After the machine has not been used for a certain
period of time (2-3 hours) carry out a few dry runs.
Make sure to carry out regular cleaning and
maintenance.
If the type of coffee is changed, we recommend-
ed you to contact the Technical Support Service for
the water temperature adjustment.
Adjust the grinding of the coffee according to the
degree of humidity in the environment.

List of hazards

This chapter describes possible hazards for the
user if the specific safety standards (described in this
manual) are not followed.
The appliance must be connected to an efficient
grounding system
If this is not done, the appliance can be a source
of dangerous electrical shocks as it is no longer able
to discharge electricity to earth.
Do not use running water for washing
The use of pressurized water directly on the
machine can seriously damage the electrical equip-
ment. Never use water jets to wash any part of the
appliance.
Be careful of the steam and hot water nozzles
During use, the steam and hot water nozzles
become very hot and are thus a potential source
of danger.
Handle these parts carefully. Never direct steam
or hot water jets directly on the body.
Do not work on the machine when it is supplied
with electrical power
Before carrying out any maintenance or repair
work on the machine you must turn it off using the
main switch or, better yet, disconnecting the mains
connection terminals. Never remove any body panel
when the machine is supplied with electrical power.
If you should decide not to use the appliance,
it is necessary to shut it down by disconnecting the
power supply cable from the electrical mains, clos-
ing the inflow of water from the hydraulic mains
and emptying the hydraulic system.
For the operations of disconnection from the
electrical and hydraulic mains and of release of the
water, qualified personnel has to be contacted.
Never work on the hydraulic system before hav-
ing emptied it
All work regarding the hydraulic system and the
related boiler is to be avoided when there is still
water and pressure in the system. Thus you must
empty it beforehand by closing the mains tap and
dry-running the delivery group for a short time.
Switch off the machine and turn on all the steam
and water taps. When the pressure is zero, empty
