Function of the machine
The main components of the espresso coffee
machine are the following:
BOILER
Contains hot water and steam.
COFFEE DELIVERY GROUP AND
HEAT EXCHANGERS
This is the component where the lter holder
is inserted. The hot water enters the delivery
group, where the processes of pre-infusion,
infusion and delivery of the coffee take place.
The machine comes with one heat exchanger
for each delivery group. The heat exchanger
is tted in the boiler and it’s purpose is to heat
up the fresh water coming from the mains to
the correct temperature.
HEATING SOURCE
An electric element warms the water in the
boiler.
ELECTRIC PUMP
This component is to increase the water
pressure of the mains to the correct water
pressure needed for espresso coffee
preparation which is 9 bars.
STEAM WAND
This wand delivers hot steam for milk
frothing and steaming of drinks in jugs (tea,
chocolates, etc.)
HOT-WATER TAP
This delivers hot water.
CONTROL & MONITORING DEVICES
Pressure gauge
Indicates the boiler pressure and the
working pressure of the pump.
Pressure switch
This is used to keep the boiler water
temperature constant by controlling the
heating elements, based on the boiler
pressure.
Automatic Boiler
Water Level Control: Electronic circuitry
used to the boiler water
level constant.
HYDRAULIC CIRCUIT
The hydraulic diagram shows that the
water used for the preparation of coffee
comes directly from the mains and is
heated in the heat exchangers inside
the boiler.

POSITIONING AND CONNECTIONS
Before installation the Manufacturer strongly recommend to control the water
supply system and the electrical connections.
Check the mains pressure which should not exceed 6 bar, otherwise it is
recommended the installation of a water pressure reducer.
The machine must be installed with a mains electrical switch with adequate fuses.
Attention: the machine must be connected to an efcient earthling
system (yellow-green-cable).
Check the efciency of the main drain hose (part 8). Then proceed with
the connection of the water drain hose to the machine (part 7).
Hydraulic connections:
- water inlet 3/8” BSP water (male tting)
- water drain hose internal Ø 14 mm.
The machine must be installed on a stable surface nd a good position for the
water softener (part 12). Connect the valve (part 9) to pipe (part 11). Connect
the pipe to the water inlet connector (part 5). Connect the pipe (part 7) to the
discharge recipient (part 6) and then on the general discharge (part 8). Put a
recipient under the water softener discharge pipe and let out the water for a few
minutes to clean the resin. Effect the electric connection between the feeding

cup for which you want to set the dose under the coffee group. Push the key related
to the selected dose and push it again when the correct quantity of coffee is reached.
Repeat this for dose setting of each key. Once the dose for one brewing group is set, the
same dose will be simultaneously set in the other group; however, for a more accurate
dosing, we recommend to program each group keyboard individually. The programming
operation between a key and the other has to be completed within 30 seconds,
otherwise the memory will be lost. For partial keyboard dose-setting push star key again
after the last selected dose key has been programmed.
Start up
Turn the main switch to pos. “1”. The lling process will proceed automatically.
When the boiler is lled, turn the main switch to pos. “2” to activate the heating
element’s electrical feed. Wait until boiler pressure reaches maximum working pressure
(approx. 1 bar).Open steam valve for a few seconds. Be sure Boiler pressure reaches
approx. 1 bar after releasing steam valve.
The boiler pressure is controlled by
a pressure switch. Turn screw A for
boiler pressure adjustment.
Prepare one dose of coffee. As coffee ows,
check the correct pump pressure (approx.
9 bar) on the pump pressure gauge. Pump
pressure can be adjusted using the screw A
positioned on the pump’s by-pass. A
