• DESCRIPTION OF THE MACHINE
The main features of the automatic espresso coffee machine are set out below.
AUTOMATIC MACHINE - DIGIT VERSION:
Espresso coffee machine with microprocessor controlled electronic measured dosage and
digital programming from the push-button pad.
Automatic boiler fi lling is standard.
Filter for mixed use either with ground coffee or with coffee pod upon request.
SEMI-AUTOMATIC MACHINE - “P” VERSION:
Semi-automatic espresso coffee machine with continuous delivery.
Automatic boiler fi lling upon request.
Filter for mixed use either with ground coffee or with coffee pod upon request.
- Boiler: Is used to contain the hot water and steam.
- Brewing group: is the component which, when attached to the fi lter holder (containing
the fi lter and the ground coffee), brews and delivers the beverages when supplied with hot
water.
- 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.
- Rotary pump: with a pressure control device. Serves to raise the mains pressure, usually
insuffi cient for the purpose, to 9 bars, ideal for getting the most out of the coffee.
- Steam tap: it allows 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 the pump’s operating pres-
sure.
- Pressure switches: control the pressure and the switching on of the heat sources to keep
the boiler water temperature constant.
- Level gauge: shows the water level in the boiler.
- Thermostats: allow the temperature adjusting.
- Warning lights: show the boiler fi lling and the switching on of the heat sources.
- Cappuccinatore (if present): this device is used to “froth” the milk to prepare cappuc-
cino.
- Cup-warmer (if present): system that enable the heating of cup-holding tray.
