GENERAL SAFETY NOTES
1 GENERAL SAFETY NOTES
Therepairofthesemachinescanonly be performedbyNespressoapprovedafter-sales
centers and technicians, using suitable tools and original spare parts and taking into
account the national safety regulations.
As an additional safety measure, the use of a residual current device (RCD), also called
a ground fault circuit interrupter (GFCI), in the repair centre is highly recommended.
Risk of fatal electrical shock and fire!
Mains voltage inside the coffee machine.
• Unplug appliance before cleaning.
• Never clean wet or immerse plug, cord or appliance in any fluid.
• Disconnect the mains plug before disassembly - the appliance must
be free of voltage.
This device does
not protect against
electrical shock due to
contact with both circuit
conductors.
Example illustrations
of typical devices.
Use a GFCI with a trip
levelof4-6mA(USA)
resp. a RCD with a trip level
of 15 - 30 mA (Europe).
A trip level above 30 mA
provides only very limited
protection against harm
from an electric shock.
1) RCD protected socket-outlet
2) Plug-in RCD unit 3) GFCI socket 4) Plug-in GFCI
Danger of burns!
Hot parts and water under pressure inside the coffee machine
(particularly in the thermoblock).
• Let coffee machine cool down before cleaning or disassembly.
