Be extremely cautious when removing a tray, basket, or rack if it contains hot oil, grease, or other hot liquids. Do not clean with metal scouring pads. Metal fragments can break off the pad and touch electrical parts, creating a risk of electric shock. Clean the crumb tray after using. Accumulated grease and crumbs can overheat and catch fire. Do not store anything on top of your oven while it is operating. Do not store anything inside your oven other than recommended accessories. Do not operate with a separate remote-

control system. Only use as directed in this manual. Not for commercial use. Household use only. Close supervision is necessary when the oven is used by or near children. While Cooking When the oven is not in use, and before To avoid risk of fire or electric shock, do cleaning, unplug it from the outlet. Allow to cool completely before putting on or taking off parts. Do not use your oven if it is damaged, not working, or if the cord or plug is damaged. Contact Customer Support

Use extreme caution when using foil, and always fit foil as securely as possible. If the foil contacts the ovens heating elements, this can cause overheating and risk of fire. 4 Never put baking or parchment paper into the oven without food on top. Air circulation can cause paper to move and touch heating elements. Always use heat-safe containers. Be extremely cautious if using containers that arent metal or glass. Keep your oven away from flammable materials (curtains, tablecloths, walls, etc.). Use on a flat, stable, heat-resistant surface away from heat sources or liquids. Press START/CANCEL to cancel cooking. The indicator light will turn off. If necessary, press and hold the TIME/TEMP knob to turn off the display. Immediately press START/CANCEL to cancel cooking and unplug your oven if you see dark smoke coming out. Food is burning. Wait for smoke to clear before opening the oven door.

Note: The heating elements do not exceed 60 minutes on in a two-hour period to maintain the set temperature. Power & Cord Your oven has a 3-prong grounding plug, and should only be used with 120V, 60Hz electrical systems in North America. Always plug in to a grounded electrical outlet. Do not modify the plug in any way. Do not let the power cord (or any extension cord) hang over the edge of a table or counter, or touch hot surfaces. If the power-supply cord is damaged, it must be replaced by Arovast Corporation or similarly qualified persons in order to avoid an electric or fire hazard. Please contact Customer Support

(see page 34). The power-supply cord should be a grounding-type 3-wire cord. 120V, 60Hz 220-240V A short power-supply cord is provided to reduce the risk resulting from becoming entangled in or tripping over a longer cord. Longer extension cords are available and may be used if care is exercised in their use. If a longer extension cord is used:

The marked electrical rating of the extension cord should be at least as great as the electrical rating of the air fryer toaster oven. The cord should be arranged so that it will not drape over the countertop or tabletop where it can be pulled on by children or tripped over unintentionally. The cord should be a grounding-type 3-wire cord. Electromagnetic Fields (EMF) This oven complies with all standards regarding electromagnetic fields (EMF). If handled properly and according to the instructions in this user manual, the appliance is safe to use based on scientific evidence available today.

Cleaning the Accessories Note:

The walls on the inside of the oven have a nonstick coating for easy cleaning. Do not use abrasive cleaners, metal scouring pads, or metal utensils on any part of the oven, including trays and other accessories. These will scratch or damage their surfaces. This oven contains no user-serviceable parts. Any repairs should be performed by an authorized service representative. 1. Before cleaning, turn off and unplug the oven, and allow it to cool completely. Open the door for faster cooling. 2. Apply non-abrasive liquid cleanser or a mild spray solution to a soft, damp cloth or sponge (not the oven surface) and wipe all parts of the oven. Do not use a dry cloth on the display screen, or it may be scratched. 3. To clean the glass door, use a glass cleaner or mild detergent and a soft, damp sponge or soft, plastic scouring pad. 4. Let all surfaces dry completely before plugging in or turning on the oven. Note:

After each use, slide out the crumb tray and discard crumbs. Only Food Tray is dishwasher-safe. 1. 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. 2. For stubborn grease:

a. 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. b. Use a sponge to spread the paste on the trays and scrub. Let the trays sit for 15 minutes before rinsing. c. Wash trays with soap and water. 3. Dry thoroughly. 4. Replace the crumb tray into the oven before plugging in or turning on the oven. Storage 1. Clean and dry the oven and all accessories. 2. Insert the crumb tray into the oven. Insert the rack at mid position. Make sure the oven door is closed. 3. Store the oven in an upright position. Do not store anything on top. 29 TROUBLESHOOTING Problem Possible Solution The oven will not turn on. Make sure the oven is plugged in. Food is not completely cooked. Food is overcooked or burned. Increase cooking temperature or time. Decrease cooking temperature or time. Make sure food items are not too large and are not touching the heating elements. Preheat the oven manually by using the Toast function set to Level 4. Food is cooked unevenly. Make sure food items are not too closely packed into a tray, rack, or other container. The oven may produce some white smoke or steam during cooking. This is normal. White smoke or steam is coming out of the oven. During first use, dust from the packing process may cause white smoke. This is normal for ovens and many other kitchen appliances. To eliminate any dust, see Test Run (page 10). Excess oil or fatty foods may produce white smoke. Make sure the inside of the oven is cleaned properly and not greasy. Dark smoke is coming out of the oven. Immediately press START/CANCEL and unplug your oven. Food is burning. Wait for smoke to clear before opening the oven door. A thermometer shows that the oven temperature is different from the oven setting. Commonly used thermometers usually have low sensitivity and take over 10 minutes to measure the correct temperature. This will not affect cooking.

If your problem is not listed, please contact Customer Support (see page 34). 30 VESYNC APP TROUBLESHOOTING Problem Possible Solution Why isnt my oven connecting to the VeSync app?

During the setup process, you must be on a secure 2.4 GHz Wi-Fi network. Confirm that the network is working correctly. Make sure the Wi-Fi password you entered is correct. Turn on Bluetooth on your phone (for Android users, make sure Location is turned on as well). Make sure your oven and phone are within 30 ft / 10 m of each other. Reset the oven by pressing and holding until starts blinking, then try connecting again. Make sure the oven is plugged in. The oven may appear to be offline if it is unplugged, or if the outlet does not have power. Refresh the VeSync menu by swiping down on the screen. My oven is offline. Make sure your router is connected to the internet and your phones network connection is working. Delete the oven from the VeSync app. Swipe left (iOS) or tap and hold (Android), and tap Delete. Then reconfigure your oven with the VeSync app. Note: Power outages, internet outages, or changing Wi-Fi routers may cause your toaster oven to go offline.
