IMPORTANT SAFEGUARDS
Follow basic safety precautions when using your air fryer oven.
Read all instructions.
Key Safety Points
- Do not touch hot surfaces. Use handle.
- The outside of the air fryer, including the door, is hot during and after use.
- Always use heat-resistant gloves, pads, or air fryer mitts when handling hot materials, and when placing items in or removing items from the air fryer, including trays, racks, accessories, or containers.
- Do not block any ventilation openings. Hot steam is released through openings. Keep your hands and face clear of openings
General Safety
- When the air fryer is not in use, and before cleaning, tap
to turn it off, then unplug from outlet. Allow to cool completely before putting on or taking off parts. - To protect against electric shock, do not immerse the air fryer, cord, or plug in water or liquid.
- Close supervision is necessary when the air fryer is used by or near children.
- Children should be supervised to ensure that they do not play with the air fryer.
- Do not use your air fryer if it is damaged, not working, or if the cord or plug is damaged. Contact Customer Support.
- Do not use third-party replacement parts or accessories, as this may cause injuries.
- Do not use outdoors.
- Do not place the air fryer or any of its parts on a stove, near gas or electric burners, or inside a heated oven.
- 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 drip tray after using.
Accumulated grease and crumbs can overheat and catch fire. - Do not store anything on top of your air fryer while it is operating. Do not store anything inside your air fryer other than recommended accessories.
- The air fryer is not intended to be operated by means of an external timer or separate remote-control system.
- Only use as directed in this manual. Do not use air fryer for any purpose other than its intended use.
- This air fryer is not intended for use by persons (including children) with reduced physical, sensory, or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the air fryer by a person responsible for their safety.
- Do not allow children to clean or perform maintenance on the air fryer.
- Keep the air fryer and its cord out of reach of children.
- Not for commercial use. Household use only.
Note: See Care & Maintenance for instructions on how to clean accessories.
While Cooking
- To avoid risk of fire or electric shock, do not place oversized foods or metal utensils (except official COSORI accessories) into the air fryer.
- Do not place paper, cardboard, or non-heat-resistant plastic into your air fryer, or any materials which may catch fire or melt.
- To avoid overheating, do not use metal foil in the air fryer unless directed. Use extreme caution when using foil, and always fit foil as securely as possible. If the foil contacts the air fryer's heating elements, this can cause overheating and risk of fire.
- Do not cover the drip tray or any part of the air fryer with metal foil, except for the food tray and air fryer tray as directed.
- Never put baking or parchment paper into the air fryer 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 aren't metal or glass.
- Keep your air fryer away from flammable materials (curtains, tablecloths, walls, etc.). Use on a flat, stable, heat-resistant surface away from heat sources or liquids.
- Immediately turn off and unplug your air fryer if you see dark smoke coming out. Food is burning. Wait for smoke to clear before opening the air fryer door.
- When unplugging the air fryer, be cautious of hot surfaces.
Power & Cord
- This air fryer uses a short powersupply cord to reduce the risk of entangling or tripping.
- Your oven has a polarized plug (one prong is wider than the other), which fits into a polarized outlet only one way. If the plug does not fit, reverse the plug. If it still does not fit, do not use the plug in that outlet. Do not alter 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.
- 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.
- 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.
Extension Cords
- 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 cord set or extension cord should be at least as great as the electrical rating of the 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.
Electromagnetic Fields (EMF)
This air fryer 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.
Place drip tray inside with handle facing out.

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.

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
![COSORI - CAF-R121-SUS - Rotisserie Handle 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.

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 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 into the air fryer before plugging in or turning on the air fryer.
Storage
- Clean and dry the air fryer and all accessories.
- Insert the drip tray into the air fryer. Insert the rack at mid position. Make sure the air fryer door is closed.
- Store the air fryer in an upright position. Do not store anything on top.
