User manual Ceramic Cooktop



IMPORTANT: When a cooking zone is switched on it may hum briefly. This is a characteristic of all ceramic glass cooking zones and does not impair either the function of the life of the appliance.

Controlling the temperature - single zone

  • To increase the heat, turn the control knob clockwise.

  • To decrease the heat, turn the control knob anti-clockwise.

  • To switch off, turn the control knob to the off position.

  • When boiling water or searing food select a high setting. As soon as steam forms or the fat or oil is hot, set a lower heat setting. To end the cooking process, turn the knob to the ‘Off’ position.

IMPORTANT: The Ring Control Knobs for single cooking zones can be turned either right or left.

Controlling the temperature - dual zone

By switching the outside ring on and off, the effective heating surface can be matched to the size of the cookware.

IMPORTANT: The inside ring must be switched on before switching on the outside ring.

  • To turn the outside ring on, turn the control knob clockwise past a slight resistance, as far as it will go. The inside ring must be switched on before turning on the outside ring.

  • Turn the control knob anti-clockwise to reach the desired setting.

  • To switch off, turn the control knob to the off position.


  • For optimal results use good quality cookware with a heavy flat base. Cookware made of enamelled or with aluminium or copper bottoms can leave discolourations on the glass ceramic surface which are difficult or impossible to remove.


  • Always place the cookware on the cooking zone before it is switched on.
  • If possible, always place the lids on the pans.
  • Switch the cooking zones off before the end of the cooking time to take advantage of the residual heat.
  • Ensure the bottom of the pan is the same size as the cooking zone you are using

  • The hob is to be connected to the mains using a device that allows the appliance to be disconnected from the mains at all poles with a contact opening width of at least 3mm. eg. automatic line protecting cut-out, earth leakage trips or fuse. A cable with a minimum temperature rating of V90HT or higher must be used as the mains connecting cable.
  • The connection must be carried out as shown in the diagram. The connecting links should be fitted according to the appropriate connection diagram. The earth lead is connected to terminal

Connection cable

  • Use the correct mains cable of type H05BB-F Tmax 90°C (or higher) for a single phase or two phase connection.
  • Replace the damaged mains cable with a special cable (type H05BB-F TMAX 90°C or higher) WHC323BC: 3 x 1.5mm² with and all-pole 16A breaker. The others: 3 x 2.5mm2 with an all-pole 25A breaker. Speak to your local Service Centre.

Assemble spring clips as shown, to support unit in benchtop.

The cooktop must be installed at least 50mm from any combustible surface.

H* - refer to rangehood manufacturers installation instructions for minimum height from cooktop.

NOTE: The clearance must meet or exceed the minimum recommended for both the rangehood and cooktop. Refer to the rangehood installation manual.

IMPORTANT: It is recommended to centre the bench cutout with equal distance front and back as shown but the product has also been certified to be installed with no clearance between the rear edge of the cooktop glass and rear wall if required. In doing need to leave sufficient clearance to so, installers still take into account that the glass dimensions are larger than the cut out.
