COMMON–SENSE PRACTICES/GOOD HABITS:

• DO NOT leave your toaster oven unattended while making food. If possible, unplug the oven while not in use to eliminate the possibility of accidents occurring.
• Have a fire extinguisher or fire containment blanket handy in a safe, known location. If you don’t have a fire extinguisher, douse the flames with baking soda until they are put out.
• If a fire occurs and the food in the oven is not greasy, immediately unplug the unit and douse the flames with water until the fire is extinguished. DO NOT use water if grease is present, since it could make the fire worse. Use baking soda instead.

ACCESSORY PLACEMENT

The oven has 4 available rack positions where your accessories can slide into the unit (see image above). When you select a function, the corresponding rack number(s) will illuminate on the control panel. The numbers on the control panel (see Fig. 1) will coincide with those on the interior of the unit. See the chart on page 8 for further details.

BEFORE FIRST USE

1. Remove and discard any packaging material, promotional labels, and tape from the unit.

2. Remove all accessories from the package and read this manual carefully. Please pay particular attention to operational instructions, warnings, and important safeguards to avoid any injury or property damage.
3. Wash the air fry basket, sheet pan, wire rack, roast tray, and removable crumb tray in warm, soapy water, then rinse and dry thoroughly. DO NOT put sheet pan, roast tray, or removable crumb tray in the dishwasher. Finishes may degrade. NEVER submerse the main unit in water.

We recommend placing all accessories inside the oven and running it on Air Roast at 450°F for 20 minutes without adding food. This removes any residues. This is completely safe and not detrimental to the performance of the oven

NOTE: The accessories are hand-wash recommended. The air fry basket and wire racks can be put in the dishwasher, but may wear more quickly over time.

USING THE COOKING FUNCTIONS WITH RACK LEVELS

As you select a cook function, the control panel will illuminate the recommended rack height(s). The chart below outlines these recommendations along with the suggested accessories. For best results, use only the recommended accessories for a given function and remove others from the oven.

NOTE: When cooking greasy, drippy foods on one level, place the Sheet Pan on the Wire Rack below to catch the drippings. Alternatively, use the Roast Tray on top of the Sheet Pan.

NOTE: Always place Sheet Pan on Wire Rack, DO NOT place directly on heating elements.

HOW TO REDUCE SMOKE

We recommend using canola, coconut, avocado, grapeseed, or vegetable oil instead of olive oil.

The unit may produce smoke when cooking on a hotter setting than what is recommended.

   • NOTE: Empty crumb tray frequently. Hand-wash when necessary
   • 
3. After every use, wipe away any food splatter on the interior walls and glass door of the unit with a soft, damp sponge.
4. To clean the exterior of the main unit and the control panel, wipe them clean with a damp cloth. A non-abrasive liquid cleanser or mild spray solution may be used. Apply the cleanser to the sponge, not the oven surface, before cleaning.
5. When using accessories, we recommend greasing them with recommended cooking oil, or covering them with parchment paper or aluminum foil before placing food on top. DO NOT cover roast tray holes with parchment paper or aluminum foil.

CLEANING THE THERMOMETER

1. DO NOT place the thermometer or holder in the dishwasher. 1 Unplug the thermometer from the unit and allow it to cool down before cleaning.
2. Hand wash the thermometer tip and silicone grip.
3. To deep clean the thermometer, soak the stainless steel tip and silicone grip in warm, soapy water. DO NOT immerse the cord or jack in water or any other liquid. NEVER use liquid cleaning solution near the thermometer jack. We recommend using compressed air or a cotton swab to avoid damaging the jack.

DEEP CLEANING

1. Unplug the unit from the outlet and allow it to cool down before cleaning.
2. Remove all accessories from the unit, including the crumb tray, and wash separately. Use a non-abrasive cleaning brush to more thoroughly wash the air fry basket. Accessories are hand-wash recommended. The air fry basket and wire racks can be put in the dishwasher, but may wear more quickly over time. DO NOT place roast tray, sheet pan, or crumb tray in dishwasher.
3. Use warm, soapy water and a soft cloth to wash the oven’s interior and glass door. DO NOT use abrasive cleaners, scrubbing brushes, or chemical cleaners, as they will damage the oven. CAUTION: NEVER put the main unit in the dishwasher or immerse it in water or any other liquid.
4. To remove tough grease, let sheet pan and roast tray soak overnight in warm, soapy water, then wash with a nonabrasive sponge or brush.
5. Thoroughly dry all parts before placing them back in the oven

FAQ

Why won’t the oven turn on?

• Make sure the power cord is securely plugged into the outlet.
• Insert the power cord into a different outlet.
• Reset the circuit breaker if necessary.
• Press the power button.

Can I use the sheet pan instead of the air fry basket with Air Fry function?

• Yes, but crispiness results may vary. Do I need to adjust the cook times and temperatures of traditional oven recipes?
• For best results, keep an eye out on your food while cooking. Refer to cook charts in the Inspiration Guide for more guidance on cook times and temperatures.

Can I restore the unit to its default settings?

• The oven will remember the last setting used for each function, even if you unplug it. To restore the oven’s default settings for each function, press the Light and 2 LEVEL buttons simultaneously for 5 seconds

Why do the heating elements appear to be turning on and off?

• This is normal. The oven is designed to control temperature precisely for every function by adjusting the heating elements’ power levels.

Why is steam coming out from the oven door?

• This is normal. Foods with a high moisture content may release steam around the door. Why is water dripping onto the counter from under the door?
• This is normal. The condensation created by foods with a high moisture content (such as frozen breads) may run down the inside of the door and drip onto the counter.

Why is the unit generating smoke?

• Ensure you are using the roast tray when cooking all greasy foods or when cooking in Air Fry, Air Roast, or Whole Roast modes.
• If problem persists, run a Toast cycle on shade 7 with accessories removed; this will burn off any additional grease on the heating elements that are causing smoke.

Why is my food overcooked or undercooked even though I used the thermometer?

• It is important to insert the thermometer lengthwise into the thickest part of the ingredient to get the most accurate reading. Make sure to allow food to rest for 3–5 minutes to complete cooking. For more information on recommended doneness while using the MANUAL function and doneness temperatures while using the PRESET function, refer to the Using the Foodi™ Thermometer section.

Will the thermometer grip melt if it touches the heating elements inside the oven?

• Make sure the grip does not touch any of the heating elements inside the oven.

How can I clean the sheet pan?

• For stuck-on food, let the sheet pan soak before cleaning.
• Line the sheet pan with aluminum foil or parchment paper when cooking to make clean-up easier.

Why did a circuit breaker trip while using the unit?

• The unit uses 1800 watts of power, so it must be plugged into an outlet on a 15-amp circuit breaker. It is also important that the unit be the only appliance plugged into an outlet when in use. To avoid tripping a breaker, make sure the unit is the only appliance plugged into an outlet on a 15-amp breaker.
