Miele HR 1421 Installation Instructions Manual page 9


A damaged range can be dangerous. Always check for visible
signs of damage. Never use a damaged appliance.

Reliable and safe operation of the range can only be guaranteed if
it is connected to the public power supply.

The electrical safety of the range can only be guaranteed when it
is properly grounded. Compliance with this essential safety
requirement is absolutely mandatory. If in any doubt, please have
the building's wiring system inspected by a qualified electrician.

To avoid damaging the range, make sure that the connection data
(voltage and frequency) on the data plate correspond to the
building's power supply before connecting the appliance.
When in doubt, consult a qualified electrician.

During installation, maintenance and repair work, e.g. if the oven
lighting is broken (see "Frequently asked questions"), the range must
be completely disconnected from the household electricity supply.
The gas supply must be shut off. Ensure that this is the case by:
– removing the fuse,
– "tripping" the circuit breaker, or
– unplugging the unit. Pull the plug not the cord.
– Shut off the gas supply and, if necessary, disconnect the range
from the gas line. Installation and maintenance of the gas
connection must be performed by qualified installers, service
agencies or gas providers.

Do not use a power strip or extension cord to connect the range
to electricity. These are a fire hazard and do not guarantee the
required level of appliance safety.

Any contact with live connections or tampering with the electrical
or mechanical components of the range will endanger your safety
and may lead to appliance malfunctions.
Do not open the appliance housing under any circumstances.
