1. General Warnings and Safety Specifications
1) This operating manual is an integral and essential part of
the product and must be supplied to users. Users are
asked to read the enclosed warnings and cautions carefully,
as they provide valuable information concerning safety
English
during installation, operation and maintenance. This
manual must be kept in a safe place and be available for
consultation to new and experienced users alike.
2) Ensure product’s integrity by inspecting the packaging,
making sure it presents no signs of damage which might
have affected the enclosed machine.
3) Check the machine’s integrity after having carefully
removed the packaging.
Note:
In case of doubt, do not go on any further and contact your
dealer or retailer immediately. They will send out specialized
personnel authorized to perform service on the espresso
machine.
4) Packaging (boxes, plastic bags, foam parts and whatever
else) must not be left around within easy reach of children,
due to the potential danger it represents, nor be discarded
in the environment.
5) Check to see that data on the rating plate corresponds to
those of the main electrical supply which the machine will
be hooked up to.
6) The installation must be performed according to local
electrical and plumbing codes and regulations. The
installation also must comply to the manufacturer’s
instructions, and must be performed by qualified and
authorized personnel.
7) Incorrect installation may cause for injury/damages to
people, animals or objects, for which the manufacturer shall
not be held responsible.
8) Safe electrical operation of this device will be achieved
only when the connection to the power outlet has been
completed correctly and in observance of all local, national,
and international electrical codes and safety regulations,
and particularly by grounding the unit. Make sure grounding
has been done properly as it represents a fundamental
safety requirement. Ensure qualified personnel check such
connection.
9) Furthermore, you must ensure that the capacity of the
available electrical system is suitable for the maximum
power consumption indicated on the espresso machine.
This device must be used exclusively for the functions it
11)
has been designed and built for. Any other application is
inappropriate and dangerous.
The manufacturer shall not be held responsible for any
damages caused by improper and/or irrational use.
12) Using any electrical device requires that certain
fundamental rules be observed. In particular:
- do not touch the device with wet or humid hands and feet;
- do not use the device while having no shoes on your feet;
- do not use extension cords in bath or shower rooms;
- do not unplug the device from the power outlet by pulling on the power
supply cable;
- do not expose the device to atmospheric agents (rain, sun, etc.);
- do not allow children or untrained people to use this device.
13) Before carrying out any maintenance and/or cleaning
operations, turn the main switch, which is located on the
front left of the machine, to the “0” or OFF position, and
disconnect the machine from the electrical network by
unplugging the cord or by switching off the relative circuit
breaker. For any cleaning operation, follow exclusively the
instructions contained in this manual.
14) In case the machine is operating in a faulty manner or
breaks down, disconnect it from the electrical network (as
described in the preceding point) and close the water
supply valve. Do not attempt to repair it. Contact a qualified
and authorized professional to perform any repair. Any
repairs must be performed exclusively by the manufacturer
or by an authorized centre using only original parts. Non
compliance with the above could compromise the safe
operation of the machine.
15) You should plan to make use of an omnipolar connector
during installation, as required by local, national, and
international electrical codes and regulations.
16) In order to avoid dangerous overheating problems, it is
recommended that the power supply cable be fully unfurled.
17) Do not obstruct air intake and exhaust grilles and, in
particular, do not cover the cup warmer tray with cloths or
other items.
18) The machine’s power supply cable must not be replaced
by users. In case the power supply cable becomes
damaged, shut off the machine and disconnect the machine
from the electctrical network by switching off the relative
circuit breaker and close off the water supply; to replace
the power supply cord, contact qualified professionals
exclusively.
10) We do not recommend using adapters, multiple plugs and/
or extension cords. If you cannot avoid using them, make
sure that they are exclusively of the kind which conforms to
local, national, and international electrical codes and safety
regulations, being careful not to exceed the power and
current ratings indicated on such adapters and extension
cords.

2) General Description
The machine is built in 2, 3, and 4 group versions and is
essentially composed of the following parts:
1) Steam Boiler (produces steam and hot water)
English
2) Coffee (“saturation”) boiler
3) Brewing groups
4) Exterior Cover
5) Water pump
3) Description of the various parts
• Steam Boiler
The Steam Boiler consists of a cylindrical tank, of varying
length according to the number of coffee groups, which is
made of AISI 300 series stainless steel. Each unit is
subjected to a hydraulic test, at a pressure of 6 bar, and has
an operating pressure of 1.3-1.5 bar. The following is a list
of effective volumes and power ratings according to the
number of groups installed:
2 groups 7.0 liters 2000 or 3000 Watts
3 groups 11 liters 3000 or 4000 Watts
4 groups 14,5 liters 3000/3800 or 5000 Watts
Covers are installed at either end of the cylindrical tank and
on one of them there is a housing for the water heating
element, which allows the steam boiler to operating
pressure within approximate 25 minutes. Operating
pressure is maintained by a pressure switch or a
temperature probe. The steam boiler has various fittings
used for safety devices, for supplying hot water and steam,,
and for the heating element.
• Exterior Cover
It consists of a stainless sheet steel body for the GB/5 and
painted plastic for FB/80. The structure has been the object
of specific studies to provide good aesthetics, to lower
ergonometric costs for the operator and to reduce the chance
of damage to a minimum.
• Water Pump
The water pump, is a differential pressure, “positivedisplacement” type installed on the water supply tubing and
is set-up to operate anytime the coffee groups are activated,
and through an electric level gauge whenever the steam
boiler needs to be replenished.
The Coffee Boiler and Steam Boiler contain water at elevated temperature.
Water temperature over 125 F / 52 can cause severe burns instantly or

• Coffee Boiler
The Coffee Boiler consists of a cylindrical tank, of varying
length according to the number of coffee groups, which is
made of AISI 300 series stainless steel.
Each unit is
subjected to a hydraulic test, at a pressure of 18 bar, and
has an operating pressure of 9 bar. The following, table is a
list of effective volumes and power ratings according to the
number of groups installed:
2 groups 3.4 liters 1400 Watts
3 groups 5.0 liters 1600 or 1900 Watts
4 groups 3.4 + 3.4 liters 1400 + 1400 Watts
(2 Boilers Installed)
Covers are installed at either end of the cylindrical tank and
on one of them there is a housing for the water heating
elements. The temperature of the coffee boiler is maintained
by an electronic temperature controller (PID capable) with
an accuracy of 0.2°C. The brewing groups are installed on
the boiler.
• Brewing Groups
They consist of a precision casting made of stainless steel.
The brewing group accepts the portafilter used to hold the
ground coffee; the espresso flows through the brewing
group, through the portafilter basket, through the portafilter
spout, and into the cup(s) after the brewing button has been
pressed.
