CAUTION

The ceramic cooktop is made from ceramic glass,  

a tough durable material that withstands heating and 

cooling without breaking. However, it must be remembered

that as it is GLASS, it may break. Treat it accordingly!

Should you have any questions about the glass in your  

new appliance, please contact the Customer Care Centre 

by phoning 1300 363 640.

The heating elements are concealed under the smooth glass 

surface which has a pattern to show the location of the 

elements. The glass will retain heat for a period of time after 

the appliance has been turned off. This is indicated by a 

“HoT SURfACe” warning light. It will remain on whenever

the glass surface exceeds 60°C.

Utensils 

•   Use pans with smooth, clean & dry bottoms to  

avoid scratching or burning residue into the glass. 

•   ensure the pan bottom is the same size as the  

working element. 

•   We do not recommend ceramic glass pans because

they do not conduct heat well Stainless steel or 

enamelled saucepans are best. 

•   Do not use pans with copper or aluminium bottoms

because they can leave traces which are difficult to 

remove from the glass. 

•   If buying new utensils select enamelled steel pans with  

2-3mm thick bottoms or stainless steel pans with sandwich

bottoms 4-6mm thick. The pan bottom should be flat, or

preferably, slightly concave at room temperature so that 

it lies flat on the glass surface when hot. 

Cooking Do’s and Don’ts 

•   Do use the stored heat in the hotplate by turning the

control to “o” before the final few minutes of cooking.

•   Do not place heat resistant mats, wire mats or

aluminium foil under pots and pans. 

•   Do not allow pots and pans to boil dry, as damage  

to both pan and hotplate may result. 

•   Do not use round bottom woks, wok stands or similar

utensils which could lead to overheating of the 

hotplates and possible damage to the cooking surface. 

•   Do not slide pans across the surface of the ceramic

glass cooktop, it could result in scratching of the surface. 

•   Do not use the cooktop as extra bench space or as  

a cutting board. 

•   Do not allow children on or near the cooktop at any time.

Cleaning your ceramic hotplate 

1.    Remove all spilt food and fat with a razor blade 

scraper (supplied with the unit) while the ceramic glass 

is still warm, but not hot. Wipe clean with dishwashing 

detergent on a damp cloth. 

2.   If aluminium foil, plastic items or high sugar content

liquids/foods are allowed to melt on the ceramic glass, 

these should be removed immediately with a scraper 

before the surface has cooled down, otherwise pitting 

of the surface can occur. 

  

3.   When the ceramic glass is cool, apply a suitable

cleaner (supplied with the unit). 

4.   It is important to follow the cleaner manufacturer’s

instructions. Remove any cleaning residue from the 

surface as staining of the cooktop may occur. 

5.   Do not use abrasive sponges or scourers, oven sprays

or stain removers as they may scratch the cooktop. 

6.   Any pitting, staining, scratches or other surface

deterioration is excluded from the warranty. 

7.   All stains/water marks can be removed by vigorous

cleaning, using the supplied ceramic cleaner. 

Cooking Hints 

Bringing
liquids to  
the boil

Use a high setting.  
Before the liquid begins to boil, turn to a lower
setting. This will stop the liquid from boiling over.

Using retained
heat

Cooking areas will stay hot after they are 
turned off. Turn the cooking area off before 
cooking is finished and use retained heat to 
finish cooking.

Turning to 
higher settings

If the pot does not have a lid, use a higher 
setting.

Turning to 
lower settings

If the pot has a lid, then use a lower setting. 
Use a lower setting for foods which will easily
burn eg milk, white sauce.

Cooking  
too fast

If food is cooking too fast, take the pot off  
the cooktop. Turn the knob to a lower setting. 
Let the cooking area cool down and replace 
the pot.
