Repairs and other work by unqualified persons could be
dangerous. Installation, maintenance work and repairs to electrical
appliances must only be carried out by a Miele approved service
technician.

A damaged appliance can be dangerous. Check it for visible signs
of damage. Do not use a damaged appliance.

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.

Reliable and safe operation of this rangehood can only be assured
if it has been connected to the mains electricity supply.

Before connecting the appliance to the mains supply, ensure that
the connection data on the data plate (voltage and frequency)
matches the mains electricity supply. This data must correspond in
order to avoid the risk of damage to the appliance. Consult a
qualified electrician if in any doubt.

Do not connect the appliance to the mains electricity supply by a
multi-socket unit or an extension lead. Extension leads are a fire
hazard and do not guarantee the required safety of the appliance.
