GENERAL SAFETY NOTES
1 GENERAL SAFETY NOTES
As an additional safety measure, the use of a residual current device (RCD), also called
the 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 cir-
cuit conductors.
Example illustrations
of typical devices.
Use a GFCI with a trip
level of 4 - 6 mA (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.
