Electricity supply
Once a satisfactory location has been established, the electrical supply to the appliance must be arranged
beneath the work surface.
The mains voltage must correspond to that which is specified on the data plate.
The supply should be from a 45 amp fused spur, with an isolator switch installed above the work surface
and to one side of the unit in case of an emergency. The isolator switch must have working contacts
separated by 3mm.
This installation must be carried out in accordance with current I.E.E Wiring Regulations and Building
Regulations (Part P).
The mains supply cable from the isolator to the unit must be rated for the maximum power consumed by
the unit (also specified on the data plate).
The supply cable must be long enough to reach the far side of the hob, plus an extra 750mm of slack to
allow for removal and servicing.
The supply cable must be routed away from hot surfaces.
Cut-out
Once you have ensured that safety requirements are met, minimum clearances have been observed, and
electrical supplies to the unit have been arranged, installation can begin.
A cut-out can be marked out on the surface as follows:
1.
Cover the approximate area for the cut-out with masking tape.
2.
Position the unit face down on the surface, ensuring that the top plate is exactly centred above the
600mm kitchen cabinet supporting the worktop, and that you have the correct clearance spaces around
the hob.
3.
Draw round the hob to mark the space that will be taken up by the top plate on the work surface.
4.
Lift the unit away to a safe distance, and check that the outline produced corresponds with the hob
dimensions (580 x 510) in Figure 2.
5.
Mark the cut-out (550 x 480 as in Figure 2) onto the masked work surface. The cut-out line should be in
a central position so that there is an even space of 15mm between the cut-out shape and the hob
outline, all the way round (Figure 3).
6.
Ensure that no pipes, hoses or wires are present as obstructions below the worktop, then cut the
opening into your work surface exactly where you have marked the cut-out shape (Figure 4).
7.
Remove the tape and ensure the area is clean and free of dust and debris.
8.
Carefully lift the hob and place it into the cut-out opening to check for a good fit.
Do not clamp the unit into place yet as arrangements must be made to connect the unit to its
electricity supply.
