Setup
Before first use, ensure all packaging materials are removed from the unit and its components. Wash the nonstick cooking baskets and crisper plates with warm, soapy water, then rinse and dry thoroughly. Place the air fryer on a clean, dry, and level surface, ensuring adequate clearance around the unit for proper ventilation. Plug the power cord into a grounded electrical outlet.
Operating Instructions
The Ninja DZ090 features a user-friendly control panel with various cooking functions. To begin, press the power button to turn on the unit. You will hear an audible beep indicating it's ready for operation.
Cooking Functions:
- Air Fry: For crispy results with little to no oil.
- Bake: Perfect for cakes, pastries, and other baked goods.
- Roast: Ideal for tender meats and vegetables.
- Reheat: Quickly warms up leftovers, restoring their original texture.
- Dehydrate: For making dried fruits, jerky, and vegetable chips.
DualZone Technology:
This air fryer is equipped with two independent 3-quart zones, allowing you to cook different foods at different temperatures and times simultaneously.
- Smart Finish: This feature allows you to cook two different foods with different settings, and have them finish cooking at the exact same time. Select the Smart Finish option, set the desired program, temperature, and time for each basket, and the unit will intelligently manage the cooking process.
- Match Cook: Easily copy the settings from one zone to the other, allowing both baskets to cook the same food with identical settings. This is useful when preparing larger quantities of a single item, utilizing the full 6-quart capacity.
