Whilst this is a photo copy, and some of the pages are a little askew, it was all readable and intact. A real bonus finding an old manual for a classic piece of kit that no other site had.
Text excerpt from page 9 (click to view)
The hob must be installed according to the instructions supplied. The hob must be installed by qualified personnel to the relevant British Standards. Please, ensure that, once the hob is installed, it is easily accessible for the engineer in the event of a breakdown.
When the hob is first installed
Once the hob has been installed, it is important to remove any protective materials, which were put on in the factory. The manufacturer will not accept liability, should the above instructions or any of the other safety instructions incorporated in this book be ignored.
Cut Out Size
The dimensions of the cut-out are given in the diagram.
Rectangular cut-out size for hob
This hob is designed to be connected to 230-240 V (50Hz) electricity supply. The hob has a terminal block which is marked as follows: L N or E - Live terminal - Neutral terminal - Earth terminal
Dimensions are given in mm.
The cable used to connect the hob to the electrical supply must be 6mm, PVC twin and earth, and fused to 30amp. It is necessary that you install a double pole switch between the hob and the electricity supply (mains), with a minimum gap of 3mm between the switch contacts and of a type suitable for the required load in compliance with the current rules. The switch must not break the yellow and green earth cable at any point.
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 (not supplied) 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.
