5. Cooking Guide & Tips
- Preheating: For best results, preheat the oven for 5-10 minutes before adding food, especially for air frying.
- Oil Usage: While air frying requires little to no oil, a light spray or toss with oil can enhance crispiness and flavor for some foods.
- Do Not Overcrowd: Avoid overcrowding the basket or racks. Cook in batches if necessary to ensure even cooking and crispiness.
- Shake/Flip: For even cooking, shake the air fry basket or flip food on racks halfway through the cooking time.
- Check Doneness: Always use a food thermometer to ensure meats are cooked to a safe internal temperature.
- Drip Tray: Always place the drip tray at the bottom of the oven to catch crumbs and drippings.

- Exterior Cleaning: Wipe the exterior with a damp cloth. Do not immerse the main unit in water.
- Accessory Cleaning: All removable accessories (air fry basket, baking pan, rotisserie fork, drip tray, etc.) can be washed in warm, soapy water or placed in the dishwasher (if dishwasher-safe, check product specifications). Rinse and dry thoroughly.
