A device must be provided in the electrical installation which allows the
appliance to be disconnected from the mains at all poles with a contact
opening width of at least 3 mm
Suitable isolation devices include line protecting cut-outs, fuses (screw
type fuses are to be removed from the holder), earth leakage trips and
contactors.
Sticking on the seal
Clean the worktop in the area of the cut-out section.
Stick the one-sided self-adhesive sealing tape supplied all the way
round the lower edge of the cooking surface along the outer edge of
the glass ceramic panel. Do not stretch it. The cut ends should lie in
the middle of one side. When you have cut it to length (add a few
mm), press the two ends flush up against one another.
