3. Switching-on
The hot plates have a single button operation. The unit is switched on
and temperature is simultaneously set on the temperature scale by
rotating the knob clockwise.
Switching-off occurs by turning in an anti-clockwise direction until the zero
marking is reached. Heating and electronic are then switched-off on all
poles.
A few details about CERAN
®
Ceran
is a non-porous glass ceramic and a registered trademark of the
company SCHOTT in Mainz.
Compared to conventional hotplates from grey cast-iron, those from

are lightweight. For example, a heating surface of 1 cm² weights
approx. 95 grams, grey cast-iron with equivalent surface are approx. 900-
1000 grams. The heating-up periods are correspondingly short. With

at approx. zero. Plate distortion through the action of heat rarely occurs.
The extremely good acid and temperature resistances should also be
noted. Sudden thermal shocks or cooling-off are optimally handled by

plate fracture
®
CERAN
is highly resistant to fracture and withstands all thermic loads.
The plates can only fracture through the mechanical use of force, e.g. by
vessels or other hard objects falling onto the plate. In this rare case of a
plate fracture, the unit is to be removed from operation and the plate must
be replaced, advantageously at the manufactories.
