3. Setup
Proper setup ensures safe and efficient operation of your oven.
- Unpacking: Carefully remove the oven and all accessories from the packaging. Retain packaging materials for future transport or storage.
- Placement: Place the oven on a stable, flat, and heat-resistant surface. Ensure there is at least 10-15 cm (4-6 inches) of clear space on all sides and above the oven for proper ventilation. Do not place the oven near flammable materials or under cabinets that are not heat-resistant.
- Power Connection: Plug the oven into a grounded electrical outlet. Ensure the voltage rating of the oven matches your household's power supply.
- Initial Cleaning: Before first use, wipe the interior and exterior of the oven with a damp cloth. Wash all accessories (bake trays, racks, grill) with warm soapy water, rinse, and dry thoroughly.
- First Use (Burn-in): To eliminate any manufacturing odors, operate the empty oven for approximately 15-20 minutes at the maximum temperature (230 °C) on the 'Bake' function. Ensure the area is well-ventilated during this process. A slight odor or smoke is normal during the first use.
4. Operating Instructions
Familiarize yourself with the control knobs for precise cooking.
Control Panel:
The oven features three main control knobs:
- Temperature Knob: Used to set the desired cooking temperature from 70 °C to 230 °C.
- Function Knob: Selects the heating mode (e.g., Top Heat, Bottom Heat, Top & Bottom Heat, Convection, Rotisserie). This oven includes a heating element select control.
- Timer Knob: Sets the cooking duration up to 120 minutes. The oven will automatically shut off and sound a bell when the timer expires. For continuous operation, turn the timer knob to the 'Stay On' position (if available).
General Operation:
- Preheating: Turn the Temperature knob to the desired temperature and the Function knob to the desired heating mode (e.g., Top & Bottom Heat). Allow the oven to preheat for 10-15 minutes, or until the indicator light turns off (if applicable).
- Loading Food: Carefully place food on the bake tray or baking rack, then slide it into the appropriate rack position inside the oven. Close the oven door securely.
- Setting Timer: Turn the Timer knob to the desired cooking time. The oven will begin heating.
- Monitoring: The internal lamp allows you to monitor cooking progress without opening the door.
- Completion: When the timer reaches zero, the oven will automatically shut off and a bell will sound. Carefully remove the cooked food using oven mitts.
Using the Convection Function:
Select a function that includes the convection fan (usually indicated by a fan symbol on the Function knob). The convection fan circulates hot air, promoting faster and more even cooking, which can be beneficial for baking and roasting.
Using the Rotisserie (Grill):
For rotisserie cooking, assemble the grill spit and forks, securing the food item. Insert the assembled spit into the designated rotisserie sockets inside the oven. Select the rotisserie function on the Function knob and set the temperature and timer as required.
5. Care and Maintenance
Regular cleaning and maintenance will prolong the life of your oven and ensure optimal performance.
- Always Unplug: Before any cleaning or maintenance, always unplug the oven from the power outlet and allow it to cool completely.
- Interior Cleaning: Wipe the stainless steel inner cavity with a damp cloth and mild detergent. For stubborn stains, a non-abrasive oven cleaner designed for stainless steel can be used, following the product instructions. Avoid harsh chemicals or abrasive scrubbers that can damage the surface.
- Exterior Cleaning: Wipe the exterior surfaces with a soft, damp cloth. Do not use abrasive cleaners or scourers.
- Detachable Front Panel: The front panel is detachable for easier access to the interior for cleaning. Refer to the specific instructions in the full manual for safe removal and reattachment.
- Accessories: Wash bake trays, baking racks, and the grill spit with warm soapy water. Rinse thoroughly and dry completely before storing or reusing.
- Door Seal: Regularly check the door seal for any damage or debris. Clean gently with a damp cloth to ensure a tight seal during operation.
