IN
DICATIONS
CAUTION
DANGER OF ELECTRIC SHOCKS
All cleaning, washing and other operations perfor-
med on the inside of the machine must be perfor-
med when the machi-
ne is in a state of
"ZERO ENERGY";
that is unplugged from
the mains.
- never use the unit
with bare feet;
- never use extension
cords in areas
equipped with baths or showers;
- never pull on the power supply cord to unplug the
unit;
- never leave the unit exposed to atmospheric
agents (rain, direct
sunlight, etc.);

unauthorized per-
sonnel or anyone
who has not read
this manual operate
the unit.
B e f o r e
performing any sort of
maintenance, the
authorized technician
must turn off the unit
and unplug it from the mains.
Before cleaning the unit set it in a state of
"0" energy: that is, "MACHINE SWITCHED OFF
AND UNPLUGGED". Follow the instructions given in
this manual carefully.
In case of breakdown or poor function,
turn off the unit. Never tamper with the unit. Contact
only professionally qualified personnel.
Only the manufacturer or an authorized service center
can make repairs and only using original spare parts.

14
Non compliance with the above can compromise
machine safety.
Upon installation, the qualified electrician
must arrange for an omnipolar switch, as called for
by the safety regulations in force; when open, the
contacts must be 3 mm or more apart.
To prevent dangerous overheating, it is
advisable to fully extend the power supply cord.
Never block
the intake and/or heat
dissipation grills, in
particular those for the
cup warmer.
The user must never replace the unit's
power supply cord. If this cord is damaged, turn off
the unit and have it replaced by a professionally
qualified technician.
Should you decide to stop using this type
of unit, we suggest you render it inoperable by
unplugging it and cutting the power supply cord.

machine in the envi-
ronment: to dispose of
the machine, contact
an authorized center
or contact the manu-
facturer for pertinent
indications.
To facilitate aeration of the unit, position
the aeration portion of the machine 15 cm from walls
or other machinery.
Once you have started washing the
machine, complete the job or residues of detergent
could be left inside the dispensing assembly.
Caution:DANGER OFINTOX I CATI O N
Be extremely careful when using the
steam nozzle. Never
place your hands
under the nozzle and
never touch it right
after use.

e
quipment (i.e. fork lift trucks).
CAUTION: DANGER OF IMPA C T
OR PINCHING
During handling, the operator must make
certain that there are no persons, things
or objects in the vicinity.
Slowly lift the pallet approximately 30 cm
o ff the ground and drive to the loading
zone. After having made certain that there
are no obstacles, things or persons in the
way, proceed with loading.
Once the destination has been reached,
again using adequate lifting equipment
(i.e. fork lift truck) and after having made
certain that there is nothing and no one in
the unloading area, set the pallet on the
ground and move it to the storage area;
always carry the load at a height of
approximately 30 cm from the ground.

unit; the machine automatically feeds
water into the boiler (initial time: approxi-
mately 3 min), once the water has rea-
ched the set level, the units starts hea-
ting and the heating light goes on.
Note: the machine has an electronic
level valve so it automatically feeds in
water to the boiler as needed to resto-
re the level.
N.B.: the machine safety system
shuts down the machine after the
pump has been running steadily
for approximately 2 minutes (this
prevents the pump from overhea-
ting). In this case, turn off the

TION: DAN-
GER OF
BURNS
When maneu-
vering the
steam nozzle
(10) you must
use the insulated potholder (10a).
2) After having set up the machine, clean
the steam nozzle with a cloth dipped in
hot water.
3) Make certain that the spout of the
nozzle is within the grill (15).
4) Gradually open the steam knob (8)

19
carefully and keep it open until any
drops of hot water that may be inside
the nozzle come out and...
5
) When only steam comes out of the
nozzle, move it with the insulating hol-
der (10a) and insert it into the liquid
you want to heat.
6
) Use knob 8 to adjust the steam as
needed.
Keep the nozzle in the liquid while
regulating the steam.
7
) Once the liquid has been heated,
close the steam knob (8) and remove
the nozzle from the heated liquid.
8

TROUBLESHOOTING
If
your espresso coffee maker is not functioning properly, see if you can find the problem in the troubleshooting list below.
A
lso reread the corresponding sections in the user's manual.
P
roblem Remedy
T
he machine does not prepare Check whether the reservoir empty light is on:
th
e espresso coffee. no water in the reservoir, or reservoir not inserted correctly.
The coffee has been ground too fine or has been pressed too hard.
The spout is plugged.
Scale must be removed from the machine.
T
he coffee comes out of the sides The filter holder was not inserted correctly.
o
f the filter holder. The filter holder was not tightened enough.
Clean coffee grinds away from the gasket (see the section on cleaning).
T
here is too little or no "cream" Check the amount of coffee: the measure must be filled level.
The machine is not hot: is the heating element off?
The coffee has not been ground fine enough.
The coffee in the filter has not been pressed correctly
