I. SAFETY PRECAUTIONS
I.I. LEVEL OF TRAINING AND
KNOWLEDGE REQUIRED OF THE
TECHNICIAN
The Technician is a specialised person that
has been specially trained and authorised to
carry out the following operations in accor-
dance with current regulations: transport and
handling, storage, installation, commissioning,
maintenance, decommissioning, dismantling
and disposal of the machine.
The Technician must be properly trained and
informed regarding any residual risks present
during these operations and while the machine
is operating.
The Technician must be able to apply all the
good practices in compliance with food hy-
giene principles.
Any unauthorised tampering with
any parts of the machine renders
the guarantee null and void and relieves
the manufacturer of any liability should
the machine malfunction or any user acci-
dents occur.
I.II. SAFETY PRECAUTIONS
Even though the machine is provided with all
safety devices required to eliminate possible
risks for the Technician, there are still certain
residual risks.
These so-called residual risks are related to ma-
chine parts that may pose a risk to the Tech-
nician, if used improperly, evaluated or deac-
tivated incorrectly, because the prescriptions
contained in this Manual were circumvented.
The machine is also equipped with appropriate
warnings placed on residual risk areas, which
must be scrupulously observed.
Attention must be paid to the residual risks that
are present during the operations described in
the following paragraphs as they cannot be
eliminated:
Compliance with the installation and ma-
chine’s safety standards is dependent on the
use, installation, maintenance and correct op-
eration of the machine. These factors are the
responsibility of the purchaser, Technician and
Technician’s employer.
The Technician’s employer is responsible for
hiring and training personnel to correctly in-
stall, run and perform maintenance work on the
machine and its protection systems.
I.III. TRANSPORT AND HANDLING
Hand crushing hazard
Handling operations must always and exclu-
sively be performed by the Technician and in
compliance with the current health and safety
regulations.
Before starting the transport and/or handling
manoeuvres, check the route, dimensions
needed, safety distances, places suitable for
placing the load down, and the appropriate
equipment for the operation.
Handling operations must be carried out by at
least 2 people, or with the help of special lifting
equipment.
In view of the substantial weight of the equip-
ment, exercise great caution during the han-
dling operations.
The Manufacturer is not responsible for any
injury or damage caused by clothing, lifting
equipment and personal equipment which was
not suitable for the type of intervention that
the operator had to carry out.
The packaging material must not be left within
the reach of children, since it is a potential
source of danger.

I.IV.INSTALLATION
Electrical hazard
High temperature hazard
Risk of explosion
It is prohibited to perform mainte-
nance on moving components
Installation operations must always and exclu-
sively be performed by the Technician and in
compliance with the current health and safety
regulations.
The appliance’s water supply must provide wa-
ter which is suitable for human consumption,
and must conform with the regulations in force
in the place of installation.
The Technician must carry out the hydraulic
connections in accordance with the hygiene
and hydraulic safety standards regarding envi-
ronmental protection which are in force in the
place of installation.
To ensure electrical safety, the appliance must
be connected to an effective earthing system,
and the system in which it is installed must be
equipped with a suitable differential circuit
breaker, in compliance with the safety laws and
standards.
The effectiveness of the earthing system and
functionality of the differential circuit breaker-
both of which are fundamental for guarantee-
ing the appliance’s electrical safety - are the
responsibility of the person in charge of the
electrical system on which the equipment is in-
stalled.
The manufacturer cannot be considered re-
sponsible for any damage caused by an inade-
quate electric system.
Make sure that the electric mains power is
enough to supply the energy needed for the
machine to correctly operate.
The appliance installation operations must be
carried out with the electrical mains switched
off. To make the electrical system safe and be
able to carry out operations when the machine
is not powered, the Technician must apply the
rules prescribed by current technical standards
(disconnect the power supply, avoid reclosures,
check that there is no voltage, etc.).
I.V. MAINTENANCE AND CLEANING
Electrical hazard
High temperature hazard
Risk of explosion
The only personnel authorised to ac-
cess the service area are those who
are knowledgeable about and have practical
experience using the appliance, particularly
in regards to safety and hygiene.
Maintenance and cleaning operations must
always and exclusively be performed by the
Technician and in compliance with the current
health and safety regulations.
The maintenance and cleaning operations
must comply with the safety regulations:
• Do not carry out maintenance work when
the machine is in operation.
• Do not immerse the machine in water.
• Do not spill liquids on the machine or use
water jets when cleaning.
• Do not allow maintenance and cleaning
operations to be carried out by children or
incompetent people.
• Do not perform maintenance and clean-
ing operations other than those described
in this manual.
When cleaning, pay attention to the parts of
the machine that can become hot:
• Avoid contact with the dispensing group,
water spouts and steam nozzles.
• Do not place your hands or other body
parts near the steam, hot water or milk
dispensing nozzle tips.

TECHNICIANS' manual 5of 88
URBAN
Only perform the maintenance and cleaning
operations indicated in this manual.
If the problem cannot be resolved, switch off
the machine and contact the Manufacturer.
All maintenance operations must be carried
out when the power supply has been turned
off, the water mains has been closed off, and
the machine has completely cooled down.
After maintenance and/or repair work, the com-
ponents that are used must ensure that the
hygiene and safety requirements initially pro-
vided for the appliance are still met. These are
met by only using original spare parts. When
components which come into contact with wa-
ter or food are repaired or replaced, a washing
procedure has to be carried out, as if it were the
rst installation.
It is the task of the Technician to in-
form the User about the methods of
periodic testing of pressure equipment and
safety devices in accordance with the legisla-
tion in force in the country of installation.
I.VI.EMERGENCY SITUATIONS
Should an emergency situation occur as a result
of a machine malfunction, adopt the measures
provided for in the emergency plan posted in
the premises and in any case, proceed to imme-
diately carry out the actions based on the type
of problem.
SHORT CIRCUIT FIRE
In the event of a re caused by the machine’s
electrical system malfunctioning, adopt the fol-
lowing behaviours:
• Disconnect the machine from the power
mains via the main switch.
• Call the re and rescue service.
• Get everyone a safe distance away from
the premises.
• Extinguish the ames using a CO2 re

2.8.1 Coffee heating unit
Each dispensing group is tted with a thermally-insulated cof-
fee heating unit (1) for dispensing hot water for coffees.
Heat is provided by an elec-
tric heating element (2). The
heating unit includes a tem-
perature sensor (3) and a
safety thermostat (4).
The temperature sensor (3)
regulates and stabilises the
water temperature inside
the coffee heating unit. The
safety thermostat (4) inter-
venes in the event of a heat-
ing system malfunction. If the
temperature reaches 150°C,
the safety thermostat intervenes by disabling the heating el-
ement and reporting the problem on the display.
2.8.2 Steam heating unit
The fully-insulated steam heating unit (5) is used to produce
steam for dispensing hot water, frothing milk via the cappuc-
cino maker or steam wand (optional), and for heating/ froth-
ing beverages.
The heating unit’s water is heated by an electric heating el-
ement (6).

2.8.3 Dispensing group
The dispensing group (A) is made up of a metallic block which
is hooked onto the coffee heating unit (B).
The functions of the group are summarised as follows:
• When the motor pump and solenoid valve (C) are ac-
tivated, which are located on the side of the group, this
allows cold water to enter the heating unit (D), and con-
sequently the hot water in the heating unit is carried to-
wards the group to be dispensed (E).
• The electric cartridge heating element (F) which is in-
stalled inside the group, is controlled by the electronic
control unit and heats the group at a programmed tem-
perature.
• The temperature sensor (G) detects the group’s tempera-
ture and sends it to the electronic control unit.
• The safety thermostat (H) cuts in to prevent any risks if
there is a failure in the electronic system.

2.8.4 Electronic control unit
The electronic control unit is the machine’s
“brain”, since it monitors and controls the ap-
pliance’s full operation.
Enter the "Menu” section (see instructions in
the next chapters) and select the but-
ton to view the installed software information
(date and version).
.
2.8.5 Volumetric dosing
The volumetric dosing device measures the quantity of water
sent to the group in order to dispense coffee.
The dispenser generates elec-
trical impulses which are sent
to the electronic control unit.
These impulses are read by
the control unit and counted
while the dose is being pro-
grammed.
The ashing LED light (4) in-
dicates that the electrical im-
pulse has been sent from the dosing device to the control unit.
2.8.6 Motor pump
This component feeds the machine
by increasing the water pressure to
0.8-0.9 MPa (8-9 bar) in order to dis-
pense coffee and automatically ll
the heating unit.

2.8.7 Automatic Water Entry
The Automatic Water Entry system is designed to check the
water level in the heating unit. It consists of:
• A level probe (short) (1) and safety probe (long) (2) - com-
prising a stainless steel rod - inserted in the heating unit.
• An electronic control unit.
• A hydraulic circuit with a motor pump and solenoid valve
which are controlled by the electronic control unit.
If the water level drops while the machine is operating nor-
mally, the level probe (1) sends a signal to the electronic
control unit, which activates the motor pump and the lling
solenoid valve, which in turn restores the water level in the
heating unit.
If the level is very low or there is no water in the heating unit
(during the machine's installation or due to a failure), the
safety probe (2) sends a signal to the control unit which deac-
tivates the heating element to keep it from overheating and
activates the motor pump and the solenoid valve to restore
the level of water in the heating unit.
To prevent any ooding caused by machine malfunctions or
leaks in the hydraulic circuit, the electronic control unit has
a “Timeout” device which stops the automatic water lling
operation after a maximum operating time.
When machines with three or four groups are being installed,
the initial water lling time may exceed the established time-
out limit. Should this occur, simply turn the machine off and
then back on to restore normal operating conditions.

2.8.8 Pressure switch
The machine has two types of pressure switches:
• COFFEE HEATING UNIT PRESSURE SWITCH
Each coffee heating unit is equipped with a pressure
switch to adjust the pressure. The calibration is set to 2
bar.
• STEAM HEATING UNIT PRESSURE SWITCH
The steam heating unit is instead tted with a safety pres-
sure switch which prevents the calibration value from be-
ing exceeded. The calibration is set to 1.5 bar.
2.8.9 Overow device
The cover installed on the pressure relief valve makes it possi-
ble to collect any water and steam which may leak from the
heating unit due to a malfunction and channel it to the drain
tray, via a special hose.
2.8.10 Pressure relief safety valve
The pressure relief safety valve has a calibration
of 0.19 MPa (1.9 bar) +/- 0.015 MPa in order to
ensure that the pressure in the steam heating unit
does not exceed 0.21 MPa (2.1 bar). Should a fault
occur, the capacity of the valve is such as to be able
to eliminate all the excess pressure in the heating
unit.
The safety valve should be checked regularly as in-
dicated in para. 10.3.5.
Two safety valves are installed on all machines
with 4 groups.
2.8.11 Expansion valve + check valve
This is a valve consisting of an expansion valve and a check
valve.
• Expansion valve (A):
the cold water sent from the pump to the heat exchangers
is heated. This heating causes an increase in the volume
of water. To limit pressure increases in
the hydraulic circuit, the valve limits
the maximum internal pressure of the
circuit to 1.2 MPa (12 bar).
• Check valve (B):
its function is to prevent the water
back-owing into the hydraulic circuit
exchangers.
2.8.12 Safety thermostat
The thermostat prevents any damage occurring to the elec-
trical heating element if there is no water in the heating unit.
The thermostat bulb (7) is located inside a sheath (8) in the
middle of the heating elements. The thermostat contacts (9)
are connected to the electric heating element (10). If the
electric heating element is exposed due to a failure to ll the
heating unit with water, the temperature of the heating el-
ement increases dramatically. At this point, the thermostat
cuts the power supply to the heating element in order to pre-
vent damage occurring.

To reset the thermostat, press the centre button
(11). However, before starting the machine up
again, identify what prevented the water from be-
ing fed into the heating unit.

2.8.13 Cup warmer
The cup warmer device warms the cups before they are used.
To activate the cup warmer, press the button.
When the bottom of the button turns red, the cup warmer is
on.
To change the cup warmer temperature, see para.
8.4.3.
2.8.14 Cappuccino maker (optional)
The cappuccino maker can be installed as an optional extra
onto a steam nozzle or installed directly onto the tap itself.
This device can both heat and froth the milk. To adjust and
clean the cappuccino maker, follow the instructions in the
user manual.
Using the appropriate tting, attach the cappuccino maker
directly to the steam nozzle, by replacing the original sprayer.
Otherwise, attach it via the appropriate hose, directly onto
the machine's steam valve.
Ensure that the sealing gasket (1) is present and if so, use
Teon tape in order to prevent any steam loss which could
negatively effect the cappuccino maker's operation.
Insert the milk suction hose (3) into the cappuccino maker's
appropriate coupling (2).
To change the temperature of the milk, attach the reducers as
shown in the table below.

2.8.15 Automatic steam wand (optional)
This system automatically froths milk at the programmed
temperature.
The operating principle is listed below:
• Select the desired button on the display, e.g. the but-
ton.
• The solenoid valve opens (2) which consequently allows
the steam to ow from the heating unit to the automatic
steam wand nozzle (9).
• Simultaneously, the system activates the air pump (6)
which is controlled by the control unit (3) and powered by
a processor (8). The milk froth can be adjusted by chang-
ing the quantity of air sucked in, by turning the valve ac-
cordingly (5).
• After passing through the non-return valve (4), the air
mixes with the steam in the "Mixing interface" (11);
• Leakage of steam from the nozzle (9);
• The probe (10) connected to the electronic unit of the ma-
chine detects the temperature of the heating milk;
• Once the set milk temperature has been reached, the elec-
tronic system stops the air and steam from being dis-
pensed.

3.4 Handling the packed machine
Upon arrival, the machine must be unloaded and handled
with care, carefully following the instructions on the packag-
ing, or those contained in this Manual.
It is very important to check that the maximum
load capacity of each piece of lifting equipment, is
at least equal to the weight of the loads to be
lifted plus the safety margins which are required by current
standards.
2.8.16 Water lter
In the mains water, non-soluble salts are
present which cause limestone to form in
the heating unit and other parts of the
machine.
Drinking water can also contain heavy
metals and substances, such as chlorine
which are harmful to health.
The lter makes it possible to eliminate
or substantially reduce the presence of
these mineral salts.
The cartridge contained in the water lter
must be replaced at the frequency speci-
ed by the manufacturer.
To use and maintain the water lter, follow the in-
structions provided in para. "10.4 Water lter
maintenance" on page 56.
2.8.17 Water softener
The resin softener can be used as an alternative to the water
lter.
This component has the property of retaining the calcium
contained in the water. For this reason, the
resins become saturated after a certain pe-
riod and must be regenerated with coarse
kitchen salt (NaCl, sodium chloride) or spe-
cial water softening salt. It is very important
to regenerate the softener within the estab-
lished times. However, in locations where
the water is very hard, it will be need to be
regenerated more frequently. The same rule
can be applied to locations where there is
a large consumption of hot water (for tea,
etc.).
To use and regenerate the water softener, follow
the instructions provided in para. "10.5 Water soft-
ener regeneration" on page 58.

3.5 Unpacking the machine
Only remove the machine from its packaging when it is ready
to be installed, in order to prevent accidental collisions which
could damage it:
• Open the packaging, taking care not to damage the ma-
chine.
• Remove and take out the machine guards and equipment
inside the packaging.
• Remove the machine.
• Dispose of the packaging in compliance with the current
waste regulations.
After unpacking the machine, check that there are
no damaged parts due to transport or missing
parts. Should there be any, immediately inform (no
later than 7 days after delivery) both the CARRIER and the
MANUFACTURER, by indicating the machine data and pro-
viding photographic evidence.
We recommend that you keep the packaging until the guar-
antee has expired.
Wood, nails, staples, cardboard: non-polluting material
which must be recycled properly.
Plastic: polluting material that must not be burned (danger
of toxic fumes), nor disposed of as normal waste; to be dis-
posed of according to current regulations.
4. STORAGE
4.1 Overview
In the waiting period prior to installation, the machine must
be stored by the Manufacturer or an Authorised Distributor.
4.2 Storing the machine after operation
If the machine is not used after a certain period of time, store
it in the following conditions:
• Disconnect the machine from the water and power mains.
• Empty all the internal circuits of water.
Store the machine taking the following precautions:
• Store in a closed environment.
• Protect it from shocks and stresses.
• Avoid contact with corrosive substances.
The machine was designed and built to operate in environ-
ments with the following characteristics:
• Room temperature: +5°C - +35°C
• Max. relative humidity: 50% (at 40°C)
Any variation in these characteristics may decrease the av-
erage life of some of the machine's components. Typical ex-
amples:
• Room temperature: premature degrading of the motors.
• Relative humidity: premature degrading of seals and elec-
tronics.
If the environmental features are signicantly dif-
ferent than those listed, contact the MANUFAC-
TURER before they become a potential problem.
Before starting the machine up after it has been
placed in storage, the equipment must be fully in-
spected.
