Installation
Preparation of the machine
The preparation of the coffee machine
and its installation must be performed by
qualified staff.
Starting the machine
Open the water tap of the water mains
and of the softener / water filter.
Turn the switch to position “1”
(electrical power supplied to the pump for
automatic boiler filling and machine
services) and wait for the boiler to be
automatically filled with water.
Turn the switch to position “2” (full
electrical power suppled, including the
heating element in the boiler) and wait for
the machine to warm up completely.
Wait for the pressure to reach its
operational pressure 1.1÷1.3 atm
checking the boiler pressure on the
gauge
Should the machine fail to stabilize on the
indicated values it is
necessary to calibrate the pressure
switch as described in calibration
paragraph.
Then check the pressure on the pump
gauge putting a unit into
operation with filter holder engaged filled
with ground, dosed and
pressed coffee in order to achieve an
effective working pressure of
8/9 atm.
Should re-calibration of the pump
pressure be necessary this
operation should be undertaken as
indicated in the “calibration” paragraph.
!
!
WARNING
Use of the machine without all the
installation operations having been carried
out by technical personnel could damage it
seriously.
WARNING
During the machine’s warm-up (roughly
20 minutes), the negative pressure valve
will release steam for a few seconds until
the valve itself closes.
Before using the machine, run deliveries
with the filter holder attached for a few
seconds to release any air which may be
in the circuit, so that the head groups are
completely heated.
The user must be provided with
instructions in order to use the machine
properly. It is recommended not to take
actions which may disturb the functions of
the machine.
WHEN THE MACHINE IS SWITCHED
ON, ITS BOILER CONTAINS STEAM

Calibration
Pressure switch adjustment
The pressure switch shown in the figure
acts to keep the
boiler pressure constant by engaging or
de-activating the electrical
heating resistance.
This pressure switch is already calibrated
to 1.1-1.3 bar during the
initial machine testing stage, but should a
different working pressure
be required, it is possible to vary the
operational field of the pressure
switch using the regulation screw (U);
pressure reduction results in
a reduction in temperature, whilst
increasing the pressure will also
increase the water temperature.
The regulation direction is shown in the
figure and on the pressure
switch itself.
The pressure varies by 0.1 atm for every
complete screw turn,
Pump pressure adjustment
Insert the filter holder into the unit filled
with regularly ground, dosed
and pressed coffee. Press one of the
coffee button and read the pressure on
the pump pressure gauge
NB: The correct pressure is of 8-9 atm.
Should the pressure indicated on the
pressure gauge be incorrect,
turn it clockwise to increase the pump
pressure and anti-clockwise
to reduce the pressure.
Once adjustment is complete check
pump calibration by delivering
one or more coffees.
Z= Pump pressure adjustment screw.

WARNING
Disconnect the electricity supply before
undertaking this operation.

Use and programming
Coffee Pouring
On pressing the corresponding button
T1-T2-T3 or T4, the corresponding
delivery solenoid valves are activated for
the time necessary to obtain the required
amount of product as previously
programmed (volumetric check).
The delivery in progress may be
suspended before actually reaching the
desired programmed product quantity by
pressing button T5 Stop.
It is also possible to obtain simultaneous
coffee delivery from all the machine
groups.
Continuously Coffee Pouring
For continuous coffee measure delivery
press button T5 from the keyboard
corresponding to the group head which
one wishes to operate. Press again the
same button T5 to Stop.
Pre infusion
Our s oft w are p erm i ts m e asu r e
configuration so that the relative delivery
of the COFFEE measures through
volumetric control is
preceded by pre-infusion. Delivery of the
coffee measure after time 1 (ON) is
suspended for a time 2 (OFF) and is then
resumed for the completion of selection.
On pressing one of the volumetric control
measure buttons, the normal delivery
cycle is preceded by a short timed water
jet in order to dampen the coffee before
actual delivery stage.
This function ensures the optimum
extraction especially for espresso
coffees.

Use and programming
Coffee measure programming
Place the programming switch in the ON
position. It is located inside the coffee
machine on the left-hand side panel of the
body. To access the inside of the machine
remove the top tray cup warmer.
The buttons T1-T2-T3-T4 will light up.
The button T5 will flash.
IMPORTANT
Programming mode
Use the button T5 to swap between pre

When the button (T1/T2/T3/T4) flashes
you are in pre infusion mode
When the buttons light up you are in

IMPORTANT
The programming of every dose must be
done with ground coffee and not with
previously used grounds. With machines
having two or three groups, by first
programming the right-hand buttons
panel the others are automatically
programmed. It is however both possible
and advisable to program the push button
panels independently, always starting
from the right-hand button panel.
