5.
The espresso coffee machine is an appliance for delivering steam/hot water for the professional preparation
of coffee or for obtaining water and/or steam.
Its long lasting, non-toxic components are easily accessible for proper cleaning and maintenance.
The user must be an adult. The machine must not be used by children or unsuitable people.
The user must comply with the safety regulations in force in the country of installation, as well as
with the rules dictated by common sense, and ensure that routine maintenance is carried out regularly and
correctly.
The installer, the user and the maintenance technician must inform the manufacturer of possible faults or
wear which could affect the system´s original safety.
The installer must check that the environmental conditions are suitable, so as to guarantee safety and
hygiene for the operators and users. The various manufacturers are responsible for the commercial
components fitted to the machine; the customer is responsible for the people authorized to use the machine.
Do not expose the machine to the weather (sun, rain, etc. ).
Long machine stoppages at temperatures as below 0ºC (zero degrees celsius) can cause damage or
breakage to the piping boiler ; thus total emptying is recommended.

Water system diagram
The water used for production of coffee does not come from the boiler . It is supplied directly from the water
net, through the heat exchangers inside the boiler. The hot water and steam surrounding the heat
exchangers, give the water inside the right temperature. This is shown in the water system diagram
Wiring diagram
The machine is connected to the power supply network by means of the electric cord supplied. See p. 35.
The main switch
The machine is fitted with a two-position power switch:
- Position 0: no power supply to the internal components.
- Position 1: power supply to the operational electric components and to the heating element.
5. Technical description Crema Compact and Digital
Do not tamper with the machine´s components or pull on the electric power cord to unplug it.
Never clean the inside of the machine with the power ON or with the plug connected and do not use
detergents or jets of water in any case.
The operator must not touch the machine with damp or wet hands or feet, or use it with bare feet.
Allthough the machine is earthed, we recommend the use of a wooden foot-board and a centralized lifesaving system to prevent the risk of electric schocks as much as possible.
Grinder shall only be used for coffee beans. All other usage could be dangerous and must seems like a
wrong and defective way to handle the machine.
The manufacturer is not responsible for damage which is caused by improper, unreasonable and/or incorrect
usage of machine.
Warning: Do not try to put in spoons, knife´s or other kitchen / housekeeping tools in the grinder
when machine is operating or in use.

5.2 Operating Principles
An espresso coffee machine is basically made up of the following elements:
Boiler
Is used to contain the hot water and steam.. Made of copper to get a equal temperature over the year.
Brewing group and heat exchanger
The brewing group is the component which, when attached to the filterholder , brews and delivers the
beverages when supplied with hot water. (Cont aining the filter and the ground cof fee or coffee pod).
The heat exchangers, one for each group, are immersed in the water and are used for fast heating of the
fresh water from the network to the optimal temperature and to prevent thermal imbalances within the system.
Heat source
This is normally provided by an electric heating element immersed in the boiler and/or by an external gas
burner , which heat the water and provide the steam.
Electric pump
This device is used to raise the pressure of the network, which is normally inadequate for the purpose, to a
pressure of 9 bars which is ideal for making the best coffee.
Steam taps
This allow steam to be delivered to give the indispensable ”froth” to the milk used for preparing cappuccino,
for heating water and punches and for preparing chocolate drinks.
Water tap
It allows water to be delivered for preparing hot drinks, tea and tisanes.
Control instruments
Manometers: show the current pressure in the boiler and in Dig. models the pump´s operating
pressure.
Pressure switchest: control the pressure and switching ON/OFF the heat sources to keep the boiler water
temperature constant.
Level gauge: shows the water level in the boiler.

7.1 Precautions for installation
The manufacturer has obviously taken every possible precaution to guarantee user safety , but the dif ferent
installation and/or transport conditions could give rise to uncontrollable or unpredictable conditions; so it is
always necessary to assess hidden hazards and to consider the following suggestions:
- The packing elements (cardboard, cellophane,metal staples, etc.) can cut, wound or cause
accidents if not handled
carefully or if used incorrectly; do not leave them accessible to children or unsuitable people.
- Any fault or defect should be promptly notified to the personnel who are qualified and authorized to
carry out installation and maintenance.
- An earthing connection is mandatory as is the system´s conformity with the regulations in force in
the country of installation. The manufacturer accepts no responsibility for accidents due to noncompliance with the regulations.
- The use of extensions or flying connections is prohibited. The working environment is heavily
exposed to water and damp which prevent the natural conditions for insulating the system.
- The machine must only be installed by authorized, qualified personnel.
- Check the condition of the components and, should defects or faults arise, stop the installation and ask
for their replacement.
- Ensure that the power supply voltage (see rating plate) is the same as that of the mains supply network
to be used in the place of installation.
- The customer must provide for the machine´s power supply, protecting the line with a suitable safety
cut-out (life-saver).
- It is important to place the machine on a flat surface! Adjust the machine feets and check with a
spirit level.
