Miele KM 3485 - Manual (Page 29)

Sealing
The cooktop must not be permanently
sealed into the countertop when
installed. The sealing strip under the
edge of the cooktop provides a
sufficient enough seal.
If the cooktop is sealed into position,
the countertop or the appliance may
be damaged if the cooktop needs to
be removed for maintenance or
service.
