local safety regulations in the country
in which the range is being installed.

water pressure to allow the appliance
to operate properly. Connection to
such a water supply could cause
poor performance, premature
appliance failure, leaks and/or
flooding. Miele will not be responsible
for any damages caused by
appliances connected to these
systems. Only use filtered, softened

Replace the stainless steel hose if it
is damaged, using only an original
Miele hose to do so (available from
Miele). The hose must be suitable for
supplying drinking water.
