COOKING WITH YOUR AIR FRYER OVEN
CAUTION:
- The outer surface of the air fryer, including the oven door, is hot during and after use. The temperature may be over 212°F. Do not touch hot surfaces. Use the handle.
- Always use heat-resistant gloves, pads, or oven mitts when handling hot materials, and when placing items in or removing items from the air fryer.
Using the Trays
Three trays are included with your air fryer: the food tray, air fryer tray, and drip tray. The cooking functions require different trays, so make sure to use the correct tray. Follow the recipe instructions or the suggestions given in each function section. Always make sure the drip tray is properly in place at the bottom of the air fryer when cooking. [Figure 1.1] The drip tray is not intended to cook food on.
Tray Positions
Each cooking function has a recommended tray position with slots that you can slide a tray into (the food tray or air fryer tray). The standard recommended positions are indicated on the front of the air fryer [Figure 1.2]. The four positions are numbered 1, 2, 3, and 4, from top to bottom.
Cooking Greasy Foods
When cooking with oil or air frying greasy food such as beef, chicken, or pork, place the air fryer tray on the food tray (or insert the food tray underneath the air fryer tray) to prevent oil from dripping on the heating elements. [Figure 1.3]
Rotisserie Handle
The rotisserie handle is used to place the rotisserie basket or fork set into the rotisserie slots in the air fryer oven. [Figure 1.4] The handle is also used to remove the rotisserie basket and fork set after cooking is finished.
Rotisserie Basket
The rotisserie basket is used for air frying small foods, such as French fries, nuggets, or Brussels sprouts.

- Use the rotisserie handle to place the basket inside the air fryer oven, securing both ends of the rotisserie shaft into the rotisserie slots.
Rotisserie Fork Set
The rotisserie fork set is used for rotating roasts and is ideal for roasting a whole chicken. Do not cook more than 4 pounds at a time on the rotisserie fork set.
- Slide the food item onto the rotisserie shaft.
- Place the rotisserie forks on either side of the shaft and insert them into the food item to secure it on the shaft. Tighten the knobs on the forks to secure them. [Figure 1.6]

Note: When cooking a rotisserie chicken, secure the legs and wings with butcher’s twine so they do not hang loosely as the chicken rotates.

CARE & MAINTENANCE
Clean air fryer accessories (including trays, etc.) and air fryer interior after every use.
Note:
- Do not use abrasive cleaners, metal scouring pads, or metal utensils on any part of the air fryer, including trays and other accessories. These will scratch or damage their surfaces.
- This air fryer contains no user-serviceable parts. Any repairs should be performed by an authorized service representative.
- Before cleaning, turn off and unplug the air fryer, and allow it to cool completely. Open the door for faster cooling.
- Apply a non-abrasive liquid cleanser or a mild spray solution to a soft, damp cloth or sponge (not the air fryer surface) and wipe all parts of the air fryer, especially the air fryer interior. Do not use a dry cloth on the display screen, or it may be scratched. Note: Make sure you clean the top of the air fryer interior after every use. If this is not cleaned, cooking residue will burn onto the air fryer interior and be difficult to remove.
- To clean the glass door, use a glass cleaner or mild detergent and a soft, damp sponge or soft, plastic scouring pad.
- Let all surfaces dry completely before plugging in or turning on the air fryer.
Cleaning the Accessories
Note: After each use, slide out the drip tray and discard crumbs.
- Apply non-abrasive liquid cleanser or a mild spray solution to a soft, damp sponge or soft, plastic scouring pad (not the accessory surface). Wipe accessories and soak in warm, soapy water if necessary.
- For stubborn grease:
- In a small bowl, mix 2 US tbsp / 30 mL of baking soda with 1 US tbsp / 15 mL of water to form a spreadable paste.
- Use a sponge to spread the paste on the trays and scrub. Let the trays sit for 15 minutes before rinsing.
- Wash trays with soap and water.
- Dry thoroughly.
- Replace the drip tray in the air fryer before plugging in or turning on the air fryer.
Storage
