Initial heating burns off any production residues. Smoke and smell may be emitted for a couple of hours; this is normal. Ensure the room is well-ventilated.

For the Electric Oven:

1. Take all baking trays and the wire shelf out of the oven.

2. Close the oven door.

3. Select the Static position.

4. Select the highest bake power.

5. Operate the oven for about 30 minutes.

6. Turn off your oven.

For the Grill:

1. Take all baking trays and the wire shelf out of the oven.

3. Select the highest grill power.

4. Operate the grill for about 30 minutes.

5. Turn off your grill.


How do I operate the electric oven function on the DEFY DBO483?

1. Set the Temperature knob to the desired temperature.

2. Set the Function knob (Selector) to the desired operating mode (e.g., Conventional Bake, Bottom Bake).

The oven will heat up to the adjusted temperature and maintain it. During heating, the thermostat indicator light stays on. When the selected temperature is reached, the light will switch off. The light will then switch on and off as the thermostat maintains the temperature.

After baking is completed, turn the thermostat and the selector knob to the “0” position in an anti-clockwise direction.

Baking Guide: Where possible, bake on the middle shelf position. Place food in the centre of the wire shelf. Do not open the oven door until at least two-thirds of the baking time has passed. The roast pan must not be used for baking purposes.


How do I operate the grill on my DEFY DBO483?

Switching on the grill:

1. Turn the Function knob to the desired grill symbol.

2. Select the desired grilling temperature (the thermostat must be on the maximum position).

3. If required, preheat for about 5 minutes. The temperature light will turn on.

Using the grill:

Both the wire shelf and roast pan can be used for grilling. The roast pan can also be used as a drip tray under the wire shelf. Position the shelf in the desired position below the grill element. After preheating, partially withdraw the shelf, place the food in the centre, and slide it back. Monitor the grilling to avoid burning. Grilling must be done with the oven door closed.

Switching off the grill:

1. Turn the Function knob to the Off position.

After grilling, the oven thermostat and selector switch must be returned to the “0” position.

What are some cooking tips for my DEFY DBO483?

Tips for baking:

• Use non-sticky coated appropriate metal plates or aluminum vessels or heat-resistant silicone moulds. Make best use of the embossed shelf runners.

• Place the baking mould in the middle of the shelf.

• Select the correct embossed shelf runner position before turning the oven or grill on. Do not change the shelf position when the oven is hot.

• Keep the oven door closed.

Tips for roasting:

• Treating whole chicken, turkey and large pieces of meat with dressings such as lemon juice and black pepper before cooking will increase the cooking performance.

• It takes about 15 to 30 minutes longer to roast meat with bones when compared to roasting the same size of meat without bones.

• Each centimeter of meat thickness requires approximately 4 to 5 minutes of cooking time.

• Leave meat in the oven for about 10 minutes after the cooking time is over to allow juices to distribute.

• Fish should be placed on the middle or lower shelf in a heat-resistant plate.

Tips for grilling:

• Distribute the pieces to be grilled on the wire shelf or in the baking tray on the wire shelf so that the space covered does not exceed the size of the grill element.

• Slide the wire shelf or baking tray into the desired level of the oven. If grilling on the wire shelf, slide the baking tray to the lower rack to collect any fats. Add some water in the tray for easy cleaning.

Tips for baking cake:

• If the cake is too dry, increase the temperature by 10°C and decrease the cooking time.

• If the cake is wet, use less liquid or lower the temperature by 10°C.

• If the cake is too dark on top, place it on a lower rack, lower the temperature and increase the cooking time.

• If cooked well on the inside but sticky on the outside use less liquid, lower the temperature and increase cooking time.

Tips for baking pastry:

• If pastry is too dry, increase the temperature by 10°C and decrease the cooking time. Dampen the layers of dough with a sauce composed of milk, oil, egg and yoghurt.

• If pastry takes too long to bake, ensure the thickness does not exceed the depth of the tray.

• If the upper side is browned but the lower part is not cooked, ensure the sauce amount is not too much at the bottom. Distribute the sauce equally for even browning.
