Technical safety

A damaged coffee machine is dangerous. Check it for any visible
damage before setting it up. Never attempt to use a damaged coffee
machine.

Before connecting the appliance to the mains supply, make sure
that the rating on the data plate corresponds to the voltage and
frequency of the household supply. This data must correspond in
order to avoid the risk of damage to the appliance. Consult a
qualified electrician if in any doubt.

The electrical safety of this appliance can only be guaranteed
when continuity is complete between it and an effective earthing
system. It is most important that this basic safety requirement is
present and tested regularly and, where there is any doubt, the
household wiring system should be inspected by a qualified
electrician.

Temporary or permanent operation with a self-sufficient or non-
mains synchronous energy supply system (e.g. isolated networks,
back-up systems) is possible. A requirement for the operation is that
the energy supply system complies with all current local and national
requirements that apply to stand-alone, solar and/or battery
systems.
The protective measures provided in the installation and in this Miele
product must also be assured in their function and operation in
isolated operation or in non-mains synchronous operation, or
replaced with equivalent measures in the installation.

Do not connect the machine to the mains electricity supply by a
multi-socket adapter or an extension lead. These do not guarantee
the safety of the appliance (e.g. danger of overheating).

This appliance must not be installed and operated in mobile
installations (e.g. on a ship).

Unplug the coffee machine from the power supply immediately if
you notice any damage or smell scorching, for example.
