Miele DAS 4940 Operating And Installation Instructions page 7


Temporary or permanent operation on an autonomous power
supply system or a power supply system that is not synchronized
with the grid power supply (e.g., island networks, back-up systems)
is possible. A prerequisite for operation is that the power supply
system complies with national and local codes.
The function and operation of the protective measures provided in
the domestic electrical installation and in this Miele product must
also be maintained in isolated operation or in operation that is not
synchronized with the grid power supply, or these measures must be
replaced by equivalent measures in the installation.

To avoid damaging the ventilation hood, make sure that the
connection data (voltage and frequency) on the data plate
correspond to the building's power supply before connecting the
appliance.
If in doubt, consult a qualified electrician.

Do not use a power bar or extension cord to connect the
ventilation hood to electricity. These are a fire hazard and do not
guarantee the required level of appliance safety.

To ensure safe operation, only use the ventilation hood after it has
been properly installed.

This ventilation hood may not be used in non-stationary locations
(e.g. on a ship).

Adequate ventilation must be provided when the hood is operated
simultaneously with devices that burn gas or other fuels.

Only open the housing as described in the enclosed "Installation
diagram" and in the "Cleaning and care" section of this manual.
Under no circumstances should any other parts of the housing be
opened.
Tampering with electrical connections or components and
mechanical parts is highly dangerous to the user and can cause
operation faults.
