1) General Description
The machine is available in a single
version. To operate the machine, it must
be connected to a steam source using the
specic connection tube. Do not use tubes
other than the one provided.
The main components that make up the
machine are:
• Steam wand;
• Platform;
• Drip tray;
• Supply tube;
• Discharge duct.
Remove machine from packaging
1) Ensure product’s integrity by inspecting
the packaging, making sure it presents
no signs of damage which might have
affected the enclosed machine.
2) Check the machine’s integrity after
having carefully removed the packaging.
Packaging (boxes, plastic bags, foam parts
and whatever else) must not be left within
easy reach of children, due to the potential
danger it represents, nor be discarded in
the environment.
2) Description of the various parts
• Steam wand
The steam wand is the component that
allows the exit of the uid. Do not touch
the wand when the machine is operating.
Although equipped with “performance
touch” technology, the wand could cause
burns as a result of a contact.
To ensure proper functioning over time
and always provide high-quality beverages,
it is recommended to clean frequently the
wand.
• Platform
The platform is the area in which to place
the pitcher. During the frothing operation,
the platform will tilt to allow the foam to
homogenise and obtain the best quality of
the foam. Do not touch the pitcher or the
platform during the frothing phase. The
platform can be removed for cleaning.
• Removable drain tray
When the machine is operating or during
cleaning, there may be accidental spills
of liquids. The drip tray allows containing
liquids to avoid they get in contact with
machine parts or that they end up on the
counter. The drip tray can be removed to
clean it in an easy manner.
• Exterior cover
The exterior consists of painted and
stainless sheet steel panels. To provide
good aesthetics, to optimize ergonometrics
for the operator and to reduce the chance
of damage to a minimum.

for use by persons (including
children) with reduced physical,
sensory or mental capabilities,
or with lack of experience and
knowledge, unless they have
been given supervision or
instruction concerning the use
of the appliance by a person
responsible for their safety.

WARNING
This appliance is not suitable
for outdoor use. Jets of water
should not be used to clean the
appliance, nor should it be placed
where water jets are used.
WARNING
In order to prevent cracks or
leakage: do not store or install
the appliance in places where
in boiler or hydraulicsystem to
freeze.
WARNING
Ensure the correct connection
of the supply tube. Improper
installation can cause the
malfunction of the machine and
may damage persons, animals
or property.
WARNING
During the lifecycle of the
machine, do not handle
improperly the connection tube
nor bring it near sharp objects
or objects that can cause the
breakage of the same. The
breach of this requirement
may cause damage to persons,
animals or property.
WARNING
It is recommended to replace
the connection pipe every ve
years, even if the machine
remains unused.
WARNING
Do not use a tube other than the
one provided with the machine.
The breach of this requirement
may cause damage to persons,
animals or property.
Note:
• The drinking water mains valve and
the circuit breakers for the electrical
system need to be located in the most
convenient position for the operator to
access them easily and quickly.
• This machine complies with the
standard 61000-3-11.

EN

1) Steam connection
Connect the supply pipe of the steam
source to the machine, ensuring the
mechanical seal of the terminal ttings
with thread 1/4” gas (BSP). If necessary,
use the adapter 1/4”-1/8” gas (BSP).
Ensure that the machine operates in a
correct manner, it is recommended to
use a source that supplies steam under
pressure between 0.14 and 0.17 MPa
(1.4 and 1.7 bar).
2) Electrical connections
Connect the appliance to a power supply
that is rated in accordance with the serial
plate on the appliance.
3) Waste water drain connection
The connection of the drain of the machine
must be realized thanks to the plastic tube
included in the supply. Connect one end of
the plastic tube to the tting of the drain
pipe under the machine, by means of the
quick connection. Connect the other end
to a suitable drain water recovery system.
If the above system is not available, and
if acceptable according to the local rules,
drain liquids can be collected in a suitable
bucket and any extensions of the drain
pipe shall use tubes in PVC and adequate
tube fasteners.

4. Operation
1) Turning the appliance on
Turn on power by pressing the main power
switch. The main power switch may be
found on the left rear of the machine.
2) Pitcher
Fill the pitcher and place it on the
platform, ensuring that the edge of the
pitcher touches the walls positioned on
the platform.
WARNING
The appliance must not be dipped
in, nor splashed with, water in
order to clean it. For cleaning
operations, please follow the
instructions listed below very
carefully.
WARNING
This appliance is designed only
for preparing hot drinks.
WARNING
To avoid the risk of injury, do not
open the brew chamber during
the brew process.
WARNING
During frothing, the platform
will tilt. Do not interfere with the
motion of the platform to prevent
machine damage and improper
milk frothing.
WARNING
You can use pitchers other than
those supplied, as long as their
outer surface is painted.
WARNING
Maintain the temperature sensor
in a good state of cleanliness.
Dirt deposited on the sensor may
compromise the operation of the
machine.
WARNING
Maintain the ultrasound distance
sensor in a good state of
cleanliness. Dirt deposited on
the sensor may compromise the
operation of the machine.

3) Select the desired program
Select the desired program by means of
the encoder.
4) Steaming milk
Press the activation button and wait for
milk frothing.
The delivery may not start if correct
frothing parameters are not respected.
Make sure the milk temperature in the
pitcher is not greater than 25°C (77°F).
Also make sure that the pitcher contains
an adequate level of milk. An excessive or
insufcient amount can lead to improper
operation of the machine. The temperature
of the milk reaches almost 60/65°C
(140/149°F).
Be careful not to allow liquid to overow in
order to avoid severe burns.
Once the milk is frothed and the wand has
returned to the upper point, it is possible
to drain. Press and hold the activation
button for the desired time for wand drain.
It is possible to drain once after each
frothing.

1) Cleaning the drain collector
Remove the drain tray grill at least twice
a week and clean, pull out the water drain
collector and clean it thoroughly. Inspect
and clean also the drain box and remove
any leftover grounds.
2) Cleaning the body
Wipe the stainless steel surfaces with a
soft, non abrasive cloth in the direction of
the glazing marks, if any. Do not use any
alcohol or solvents whatsoever on painted or
imprinted parts in order not to damage them.
3) Cleaning the steam nozzles
Steam nozzles must be cleaned
immediately after use with a damp cloth
and by producing a short burst of steam
so as to prevent the formation of deposits
inside the nozzles themselves, which may
alter the avor of other drinks to be heated.
IMPORTANT
If the appliance has not been used for
more than 8 hours or, in any case, after
long periods of being idle, in order to use
the appliance to its full potential it is
necessary to perform some cleaning cycles
before brewing beverages as follows:
- Being careful to avoid burns, turn
on each steam wand for at least one
minute.
If the appliance is not going to be used
for long periods of time, it is advisable to
follow these safety indications:
- Disconnect or interrupt the steam
connection via a mains tap.
- Disconnect the appliance from the
electrical mains.
