4. MACHINE OPERATION
It is important to have a dosing-grinding device next to the machine with which
to grind the coffee to use daily. The grinding and the dosing of the coffee must
be done according to that indicated by the manufacturer of the dosing-grinding
device. The following points are also to be kept in mind:
• to obtain a good espresso it is recommended not to keep large stocks of
coffee grains. Observe the expiry date indicated by the producer.
• never grind large volumes of coffee, it is advisable would be to have the
quantity contained in the dosing device and use it if possible by the end of
the day.
• do not purchase previously ground coffee which does not have a very long
shelf life. If necessary, purchase it in small vacuum-packed containers.
Prepare coffee in the filter holder as follows:
• fill the filter with a dose of ground coffee (circa 6-7 gr.) and press it with
the press;
• Hook the filter-holder to the group without closing too tightly in order to
avoid excessive wear of the gasket.
• For the same reason it is recommended to clean the edge of the filter
before attaching the filter holder to the delivery group.

7. SUGGESTIONS FOR OBTAINING GOOD COFFEE
To obtain a high-quality coffee, it is important that water hardness of the water used does not exceed 4-5
°F (French degrees). In the water hardness exceeds these values, it is advisable use a water softener.
Avoid using a water softener if water hardness is less than 4 °F. If the taste of chlorine in the water is
especially strong, a special filter should be installed.
It is not advisable to keep large stores 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 period of time (2-3 hours) make a few dry runs. Be sure to
carry out regular cleaning and maintenance.
6. VERSIONS WITH INTERNAL MOTORISED PUMP
For models with internal motorised pump, it is important remember that:
• there is no internal tank;
• water supply is provided by means of connection to the water mains;
• be sure to connect the tub of the machine to the drain;
• it is advisable to use a water softener.
WARNING
For further information, it is advisable to contact customer technical assistance.
8. CLEANING
For perfect cleaning and efficiency of the appliance, several simple cleaning operations are necessary on the
functional parts and accessories as well as the body panels. The indications given here are applicable for normal
use of the coffee machine. If the machine is heavily used then cleaning should be performed more frequently.
Filter and filter-holder
The filters and the relative filter-holders must be cleaned daily in
hot water. The best thing to do is to let them soak in hot water
overnight so that the fatty coffee deposits can dissolve. It is
advisable to add an envelope or tablet of special detergent to
the water, and then to rinse everything off with water.
Failure to clean the filters and filter holders daily will compromise
the quality of the coffee and will also cause problems such as
bad extraction and coffee grounds at the bottom of the cup.

ENGLISH
72 use and maintenance manual
Perforated disk and containment ring
Both the perforated disk (1) and its containment ring (2) should be
cleaned regularly in hot water. To do this, loosen the screw (3) and
remove the two elements from the dispensing unit.
Steam nozzle
The steam nozzles must be kept clean at all times. Check the ends of
the steam nozzles and clean them monthly, clearing out the exit holes
with a small needle.
Dispensing group
The cleaning of the internal parts of the delivery group is to be performed regularly in the following manner:
• replace the normal filter of the filter-holder with a solid one;
• pour a teaspoon of a suitable detergent powder on the solid filter, and attach the filter-holder to the
group;
• use the delivery switch to set the group in operation;
• repeat the above operations until the water comes out clean;
• turn off and remove the filter-holder from the group;
• rinse a final time, so as to remove any residual detergent.
Body
The body panels should be cleaned with a cloth soaked in warm water. Do not use abrasive detergents since the
panels could get scratched.
Grinder-doser
Every week clean the bell jar and the dosing device with a cloth soaked in lukewarm water, both inside and out .
WARNING
When cleaning, always use cloths that are completely clean and hygienic.

9. LIST OF HAZARDS
This chapter describes possible hazards for the user if the specific safety standards described in this booklet
are not adhered to.
The appliance must be connected to an efficient grounding system
If this is not done, the appliance can be a source of dangerous electrical discharges in that it is no longer able
to discharge electricity to earth.
Do not use running water to wash
The use of pressurized water directly on the machine can seriously damage electrical appliances. Never use
water jets to wash any part of the appliance.
Be careful with the steam nozzles and hot water
During use, the steam nozzles and hot water may overheat, thus becoming a source of danger. Handle such
parts carefully. Never direct steam or hot water jets directly on parts of the body.
Do not work on the machine when it is supplied with electrical power.
Before carrying out any intervention on the machine you must turn it off by means of the main network switch
or better yet, disconnecting the connection terminals in the network. Never remove any body panel when the
machine is supplied with electrical power.
Never work on the hydraulic system before having emptied it.
All work regarding the hydraulic system and the relative boiler are to be avoided when there is still water and
pressure in the system. You must therefore empty it beforehand, closing the mains cock and dry-running the
delivery group for a short time. Switch off the machine and open all the steam and water cocks and taps. With
the pressure zero, completely empty the boiler, unscrewing the special pipe fitting situated on the lower part
of it. If the above procedure is not correctly carried out, opening any part of the hydraulic system can cause
a sudden outlet of overheated water under pressure.
Use of the appliance
This espresso coffee machine is an appliance exclusively for professional use. Any other type of use is considered
wrong and therefore dangerous. Never allow children or incapable persons to use the machine.
Non-observance of the above-described standards can cause serious harm to people, property or animals.
Never work on the electronic apparatus when the machine is still supplied with electrical energy.
Shut down the machine completely by unplugging it from the mains before carrying out any operation.
WARNING
The manufacturer declines any responsibility for damage that can occur if the above
instructions are not followed.
