Genuine Toshiba owner's manual. Couldn't really ask for more. And written in understandable English in contrast to a few recent experiences I have had with manuals for other equipment other than Toshiba but made in China and written in "Chinglish"!

Cut Out Size
The dimensions of the cut-out are given in the diagram.
Building over a cupboard or drawer
If the hob is to be installed above a cupboard or drawer it will be necessary to fit a heat resistant board below the base of the hob on the underside of the work surface. It is also recommended to carry out the electrical connection to the hob as shown in diagrams 1 and 2.
Building over a kitchen unit with door
Proper arrangements must be taken in designing the furniture unit, in order to avoid any contact with the bottom of the hob which can be heated when it is operated. The recommended solution is shown in diagram 3. The panel fitted under the hob ("a") should be easily removable to allow easy access if technical assistance is needed. The space behind the kitchen unit ("b") can be used for connections.
Dimensions are given in mm.
Fitting the hob to the worktop
Before fitting the hob into the cut out, an adhesive seal must be fitted to the underside outside edge (diagram 4) of the hob. It is essential that no gaps are left in this seal in order to prevent spillage near the hob seeping into the cabinet below. 1) Remove the pan supports, the burners caps and crowns and turn the hob upside down, taking care the ignition candles are not damaged in this operation. 2) Place the sealing gasket all around the glass top edge as shown in diagram 4. 3) Fit the hob in the cut out and push it down until the glass top and the working top make contact, as shown in diagram 5.
