5. Setup and First Use
5.1 Unpacking
- Carefully remove all packaging materials from the appliance and its accessories.
- Check that all listed components are present and undamaged.
5.2 Initial Cleaning
- Wash all removable accessories (baskets, racks, trays, rotisserie shaft) with warm, soapy water. Rinse thoroughly and dry completely.
- Wipe the interior and exterior of the oven with a damp cloth. Do not use abrasive cleaners.
5.3 Initial Burn-In Process
Before cooking food, it is recommended to perform an initial burn-in to eliminate any manufacturing odors:
- Place the drip tray at the bottom of the oven. Apply a very light layer of cooking oil to the drip tray.
- Place a few slices of lemon on the oiled drip tray.
- Close the oven door.
- Set the oven to a 'Bake' or 'Roast' setting at approximately 350°F (175°C) for 7-10 minutes.
- Some odor or light smoke may be present during this initial use; this is normal. The lemon helps to mitigate the smell.
- After the cycle, turn off the oven, unplug it, and allow it to cool completely.
- Once cooled, wipe the interior again with a damp cloth.
5.4 Placement
Place the appliance on a stable, heat-resistant surface. Ensure there is at least 8 inches of clear space on all sides (back, top, and sides) to allow for proper air circulation and heat dissipation.
6. Operating Instructions

- Roast: Perfect for meats, vegetables, and the rotisserie function. The rotisserie function typically activates on the 'Roast' setting. Note that the internal capacity may be tight for a very large whole chicken; consider smaller poultry or cuts.

- Drip Tray & Crumb Tray: Always place these at the very bottom of the oven to catch drips and crumbs, making cleanup easier.
- Removal Tools: Use the provided handle to safely remove hot accessories like the rotating basket or rotisserie shaft after cooking.
7. Cleaning and Maintenance
Regular cleaning and maintenance will prolong the life of your appliance and ensure optimal performance.
- Always unplug the oven from the power outlet and allow it to cool completely before cleaning.
- Exterior: Wipe the exterior with a soft, damp cloth. Do not use harsh abrasives or metal scouring pads.
- Interior: Wipe the interior walls with a damp cloth and mild detergent if necessary. For stubborn food residue, a non-abrasive sponge can be used. Ensure the interior is dry before next use.
- Accessories: All non-stick accessories (rotating basket, racks, trays, etc.) are easy to clean with warm, soapy water. Rinse thoroughly and dry completely.
- Drip/Crumb Tray Care: The drip tray may show signs of warping over time due to heat exposure. To minimize this, ensure it is cleaned regularly and avoid excessive force when handling. Lining it with aluminum foil can help protect it and simplify cleaning.
- Do not immerse the main unit (housing, cord, plug) in water or any other liquid.

If you encounter issues with your CROWNFUL Air Fryer Toaster Oven, refer to the following common problems and solutions:
- Appliance does not turn on:
