List of hazards

This chapter describes possible hazards for
the user if the specific safety standards (described
in this manual) are not followed.
The appliance must be connected to an effi-
cient grounding system
If this is not done, the appliance can be a source
of dangerous electrical discharges in that it is no
longer able to discharge electricity to earth.
Do not use running water for washing.
The use of pressurized water directly on the
machine can seriously damage the electrical equip-
ment. Never use water jets to wash any part of the
appliance.
Be careful with the steam and hot water
nozzles.
During use, the steam and hot water nozzles
may overheat, thus becoming a source of danger.
Handle these parts carefully. Never direct steam or
hot water jets directly on the body.
Be careful of the outer surfaces of the delivery
group.
During normal operation, even the delivery
group overheats and thus poses a potential hazard.
Be careful not to come into contact with the outer
surfaces of the group.
Do not work on the machine when it is sup-
plied with electrical power.
Before any intervention on the appliance, turn
it off or disconnect it from the power supply. Never
remove any body panel when the machine is sup-
plied with electrical power.
Never work on the hydraulic system before
having emptied it.
All work regarding the hydraulic system and the
related boiler is to be avoided when there is still water
and pressure in the system. You must therefore empty
it beforehand, removing any water in the internal
tank and dry-running the dispenser unit for a short
time. Switch off the machine and open all the steam
and water taps. When the pressure is zero, empty the
boiler completely by unscrewing the special pipe
fitting located on the lower part of boiler.

instructions for the user
If the above procedure is not carried out correctly,
opening any part of the hydraulic system can cause
a sudden outburst of superheated water under
pressure.
Use of the appliance
This espresso coffee machine is an appliance for
professional use only. Any other type of use is con-
sidered incorrect and therefore dangerous. Never
allow children or incapacitated persons to use the
machine.
Non-observance of the above-described stand-
ards can cause serious harm to people, property or
animals.
Never work on the electronic apparatus when
the machine is still supplied with electrical energy.
Shut down the machine completely by unplug-
ging it from the mains before carrying out any
operation.
All maintenance operations must be carried out
!
after disconnecting the power supply, water
supply, and after the complete cooling of the
machine.
We recommend the use of appropriate protective
gloves.
Any action taken by a technician on the electronics
!
of the machine when the machine is still supplied
with electrical power automatically invalidates
any guarantee.
The technician needs to be aware that the machine
is electrically connected and act accordingly.
