Cut out the work surface according to the sizes shown in the drawing.
Leave a space of at least 5 cm around the hole for the purpose of installation and use.
Make sure the work surface is at least 30 mm thick. Please select a heat-resistant work
surface material to avoid extensive deformation due to the heat radiated by the hotplate.
