Defy Appliances 600C User Manual

 
Registered by Defy in 1978, Thermofan  cooking differs from conventional cooking in 
that it uses the principle of forced convection within the oven. The advantages are: 
1.  Both trays may be used at the same time. 
2.  Different dishes can be cooked simultaneously without flavour or aroma transfer. 

Hence fish, meat and cakes can be baked at the same time. 

3.  The oven door may be opened any time for inspection purposes without risking a 

flop. 

4.  By circulating hot air around the food, spit-roast chickens may be done without using 

a rotisserie. 

5.  Cooking is done at slightly lower temperatures (10°C TO 20°C lower), saving 

electricity and reducing splatter. 

 
Cooking 

•  Set the oven thermostat to the required temperature.  
•  The indicator light will glow and remain on until the oven has reached the selected 

temperature. When the indicator light switches off, the food should be placed in the 
oven. During cooking the indicator light will cycle on and off as the oven thermostat 
maintains the selected temperature 

•  After completion, the thermostat must be returned to 0.

•   Thermofan baking is done with the oven trays in position. An unused tray should be 

kept in position to facilitate proper airflow. 

•  For small items the entire area of each tray may be utilised. Larger items should be 

placed towards the front of each tray. 

•  All ovens extract a certain amount of moisture from the food being cooked. The much 

greater capacity of the Thermofan oven allows more food to be cooked and thus more 
moisture may be released. This is normal and not detrimental to the food or the oven. 

•  For professional results and perfect browning, open the oven door when half the 

baking time has lapsed. Then turn the baking tins around so that the sides previously 
facing the back of the oven now face the front. 

 
Caution: Thermofan baking relies on good contact between the bottom of the cake 
tin and the oven tray. Do not use spring form baking tins with a raised bottom.  The 
lack of contact will cause the bottom of the cake to be underdone. These tins may be 
used on a wire shelf where no insulating air space is created.
