Important Usage Features:
- Safety: Always stand back when opening the oven door to release steam/heat. It is dangerous to alter specifications or modify the product. Appliances get very hot; avoid touching heating elements. Ensure control knobs are "off" when not in use. Keep the appliance clean to prevent fat/food build-up and fire risk. Never line the oven with aluminum foil.
- Child Safety: Designed for adult operation. Children should not tamper with controls, play with the product, or touch hot surfaces. Supervise children near the oven.
- Oven door: Always catch the handle in its central part to open. Always cook with the oven door closed.
- Cooling fan: Keeps the front panel, knobs, and door handle cool. May run after the oven/grill is switched off until a normal temperature is reached.
- Cooking with turnspit: Place the spit-support frame in the second runner from the bottom. Pierce and secure food on the spit, fit the spit tip into the motor drive, and rest the front part on the frame groove. Remove the spit handle. Turn the oven function control knob to the turnspit symbol. Leave the oven door closed.
- Cooking times: Vary by food type, consistency, and volume. Experience will help in adjusting values from the cooking tables. Pre-heat the oven for about 10 minutes before cooking.
- Hints for baking cakes: Use moderate temperatures (150-200°C). Pre-heat for 10 minutes. Do not open the door for at least 3/4 of the cooking time. Ensure dough/mix consistency is not too moist.
- Hints for cooking meat and fish: Meat should weigh at least 1 kg. Red meat: 200-220°C for rare. White meat, poultry, fish: 150-175°C. Add sauce ingredients during the last half hour for longer cooking times. Check doneness by pressing with a spoon. Let meat rest for 15 minutes before carving. Pour a little water into the dripping pan to prevent smoke.
