Important Safeguards

⚠️ WARNING

Read all instructions before use. For household use only.

  1. This appliance can be used by persons with reduced physical, sensory or mental capabilities or lack of experience and knowledge if they have been given supervision or instruction concerning use of the appliance in a safe way and understand the hazards involved.
  2. Keep the appliance and its cord out of reach of children. DO NOT allow the appliance to be used by children. Close supervision is necessary when used near children.
  3. To eliminate a choking hazard for young children, discard all packaging materials immediately upon unpacking.
  4. DO NOT place appliance on a stovetop or hot surfaces or near gas or electric burner or in a heated oven.
  5. DO NOT use the appliance without the removable cooking pot installed.
  6. When removable cooking pot is empty, DO NOT heat it for more than 10 minutes, as doing so may damage the cooking surface.
  7. Children shall not play with the appliance.
  8. NEVER use socket below counter.
  9. NEVER connect this appliance to an external timer switch or separate remote-control system.
  10. DO NOT use an extension cord. A short power-supply cord is used to reduce the risk of children grabbing the cord or becoming entangled and to reduce the risk of people tripping over a longer cord.
  11. To protect against electrical shock DO NOT immerse cord, plugs, or main unit housing in water or other liquid. Cook only in the pot provided or in a container recommended by SharkNinja placed in the provided pot.
  12. Regularly inspect the appliance and power cord. DO NOT use the appliance if there is damage to the power cord or plug. If the appliance malfunctions or has been damaged in any way, immediately stop use and call Customer Service.
  13. ALWAYS ensure the appliance is properly assembled before use.
  14. Before use, ALWAYS check pressure release valve and float valve for clogging or obstruction, and clean them if necessary. Check to make sure the float valve on the pressure lid moves freely. Foods such as apple sauce, cranberries, pearl barley, oatmeal or other cereals, split peas, noodles, pasta, rhubarb, or spaghetti can foam, froth, and splutter when pressure cooked, clogging the pressure release valve. These and similar expanding foods (such as dried vegetables, beans, grains, and rice) should not be cooked in a pressure cooker, except when following a Ninja® Foodi® recipe.
  15. DO NOT cover the air intake vent, air exhaust vent or electrical socket while crisping lid is closed. Doing so will prevent even cooking and may damage the unit or cause it to overheat.
  16. To prevent risk of explosion and injury, use only SharkNinja silicone rings. Make certain silicone ring is installed and lid is properly closed before operating. DO NOT use if torn or damaged. Replace silicone ring before using.
  17. Before placing removable cooking pot into the cooker base, ensure pot and cooker base are clean and dry by wiping with a soft cloth.
  18. This appliance is for household use only. DO NOT use this appliance for anything other than its intended use. DO NOT use in moving vehicles or boats. DO NOT use outdoors. Misuse may cause injury.
  19. Intended for worktop use only. Ensure the surface is level, clean and dry. DO NOT move the appliance when in use.
  20. DO NOT use accessory attachments not recommended or sold by SharkNinja. DO NOT place accessories in a microwave, toaster oven, convection oven, or conventional oven or on a ceramic cooktop, electric coil, gas burner range, or outdoor grill. The use of accessory attachments not recommended by SharkNinja may cause fire, electric shock, or injuries.
  21. When using this appliance, provide adequate space above and on all sides for air circulation.
  22. ALWAYS follow the maximum and minimum quantities of liquid as stated in instructions and recipes.
  23. NEVER use SLOW COOK setting without food and liquids in the removable cooking pot.
  24. DO NOT use this appliance for deep frying.
  25. DO NOT cover the pressure valves.
  26. DO NOT sauté or fry with oil while pressure cooking.
  27. Prevent food contact with heating elements. DO NOT overfill or exceed the MAX fill level of the pot and the Cook & Crisp Basket or Plate. Overfilling may cause personal injury or property damage or affect the safe use of the appliance.
  28. When pressure cooking foods that expand (such as dried vegetables, beans, grains, rice, etc.). DO NOT fill pot more than halfway, or as otherwise instructed in a Ninja Foodi® recipe.
  29. DO NOT use this unit to cook instant rice.
  30. Electrical socket voltages can vary, affecting the performance of your product. To prevent possible illness, use a thermometer to check that your food is cooked to the temperatures recommended.
  31. DO NOT place the appliance near the edge of a worktop during operation.
  32. To avoid possible steam damage, place the unit away from walls and cabinets during use.
  33. Should the unit emit black smoke, unplug immediately and wait for smoking to stop before removing the cooking pot and Cook & Crisp™ Basket.

Caution: Surfaces are hot during and after operation. To prevent burns or personal injury, ALWAYS use protective hot pads or insulated oven mitts and use available handles and knobs.

Extreme caution must be used when the cooker contains hot oil, hot food, or hot liquids, or if the cooker is under pressure. Improper use, including moving the cooker, may result in personal injury. When using this appliance to pressure cook, ensure the lid is properly assembled and locked into position before use. Food are under extreme pressure during pressure cooking. Failure to follow all instructions regarding proper usage of the product may result in unintended contact with hot foods or liquids that have been pressurised, resulting in serious burns.

Caution should be used when searing meats and sautéing. Keep hands and face away from the removable cooking pot, especially when adding new ingredients, as hot oil may splatter.

When unit is in operation, hot steam is released through the air exhaust vent. Place unit so vent is not directed toward the power cord, sockets, cabinets or other appliances. Keep your hands and face at a safe distance from vent.

DO NOT tamper with, disassemble, or otherwise remove the float valve or pressure release assembly.

DO NOT attempt to open the lid during or after pressure cooking until all internal pressure has been released through the pressure release valve and the unit has cooled slightly. Remove lid promptly to avoid re-pressurisation of the inner pot.

DO NOT use Pressure Lid when Sear/Sauté function is selected.

When using SLOW COOK ALWAYS keep the pressure lid closed and the pressure release valve in the VENT position. If the lid is closed and the pressure release valve is in the SEAL position, an audible alarm will sound. "VENT" error code will appear on LED display to signal the need to turn the pressure release valve to the VENT position.

When using the PRESSURE COOK setting, ALWAYS keep the pressure lid locked and the pressure release valve turned anticlockwise to the SEAL position.

If the lid will not turn to unlock, this indicates the appliance is still under pressure. DO NOT intentionally press down on float valve. Any pressure remaining can be hazardous. Let unit naturally release pressure or turn the Pressure Release Valve slowly to the VENT position to release steam. Take care to avoid contact with the releasing steam to avoid burns or injury. When steam is completely released the float valve will be in the lower position allowing the lid to be removed. If steam does not release when the pressure release valve is moved to vent, unplug the unit from the wall and let the unit naturally release pressure.

Spilled food can cause serious burns. Keep appliance and cord away from children. DO NOT let cord hang over edge of tables or counters or touch hot surfaces.

Serious burns can result from the steam and hot foods inside the inner pot. ALWAYS keep hands, face, and other body parts away from the pressure release valve prior to or during pressure release and when removing the pressure lid after cooking.

When removing the lid, DO NOT lift the lid straight up as this may not release the seal between the lid and pot, increasing the risk of food splashing.

ALWAYS tilt the lid so that it is between your body and the inner pot so that you can be shielded from steam and hot liquids.

The cooking pot, Cook & Crisp™ Basket or Plate, and reversible rack become extremely hot during the cooking process. Avoid hot steam and air while removing the cooking pot and Cook & Crisp™ Basket or Plate from the appliance, and ALWAYS place them on a heat resistant surface after removing. DO NOT touch accessories during or immediately after cooking.

Removable cooking pot can be extremely heavy when full of ingredients. Care should be taken when lifting pot from cooker base.

Cleaning and user maintenance shall not be made by children.

Let the appliance cool for approximately 30 minutes before handling, cleaning, or storing.

To disconnect, turn any control to "off", then unplug from socket when not in use and before cleaning. Allow to cool before cleaning, disassembly, putting in or taking off parts and for storage.

DO NOT clean with metal scouring pads. Pieces can break off the pad and touch electrical parts, creating a risk of electric shock.

Please refer to the Cleaning & Maintenance section for regular maintenance of the appliance.

In order to familiarise yourself with the Pressure Cook function and start cooking, it is highly recommended for first-time users to do an initial run with water only.

  1. Place the pot in the cooker base and add 700ml room-temperature water to the pot.
  2. Assemble the pressure lid by aligning the arrow on the front of the lid with the arrow on the front of the cooker base. Then turn the lid clockwise until it locks into place.
  3. Make sure the pressure release valve on the lid is in the [SEAL] position.
  4. Turn the unit on. Press the PRESSURE button, the unit will default to high (HI) pressure. Set the time to 2 minutes. Press the START/STOP button to begin.
  5. Your Ninja® Foodi® Multi-Cooker will begin to build pressure, indicated by the rotating lights. The unit will begin counting down when it is fully pressurised.
  6. When the countdown is finished, the Ninja® Foodi® Multi-Cooker will beep, automatically switch to the Keep Warm mode, and begin counting up.
  7. Turn the pressure release valve to the [VENT] position to quick release the pressurised steam. A quick burst of steam will spurt out of the pressure release valve. When steam is completely released, the unit will be ready to open.

Diagram Description: Diagrams show the steps for the pressure test: adding water to the pot, attaching the pressure lid, setting the pressure release valve to SEAL, the control panel showing 02 minutes and the PRESSURE function active, the unit building pressure (indicated by rotating lights), and finally turning the valve to VENT to release steam.

Note: To maintain the quick release pressure, the valve will lock in to place in the [VENT] position.

Natural Pressure Release vs. Quick Pressure Release

Even after releasing pressure naturally or using the pressure release valve, some steam will remain in the unit and will escape when the lid is opened. Lift and tilt it away from you, making sure no condensation drips into the cooker base.

Note: At any time during the natural release process, you can switch to quick release by turning the pressure release valve to the [VENT] position.

WARNING: Caution HOT Steam emitted.

Pressurising

As pressure builds in the unit, the control panel will display rotating lights. Pressurising time varies, depending on the amount of ingredients and liquid in the pot. As the unit pressurises, the lid will lock as a safety measure, and it will not unlock until pressure is released. Once the unit has reached full pressure, the lid pressure icon light will glow steadily. The pressure cooking cycle will begin and the timer will start counting down.

Diagram Description: A diagram shows the pressure lid being placed on the unit, aligning arrows. Another shows the lid locked in place. A third shows the pressure release valve being turned to VENT.

Cleaning & Maintenance

Cleaning: Dishwasher & Hand-Washing

The unit should be cleaned thoroughly after every use.

  1. Unplug the unit from the wall socket before cleaning.
  2. To clean the cooker base and the control panel, wipe them clean with a damp cloth.
  3. The pressure lid and cooking pot, silicone ring, reversible rack, Cook & Crisp™ Basket, and detachable diffuser can be washed in the dishwasher.

Note: NEVER put the cooker base in the dishwasher, or immerse it in water or any other liquid.

  1. The pressure lid, including the pressure release valve and anti-clog cap, can be washed with water and dish soap.
  2. To clean the crisping lid, wipe it down with a wet cloth or paper towel after the heat shield cools.
  3. If food residue is stuck on the cooking pot, reversible rack, or Cook & Crisp Basket, fill the pot with water and allow to soak before cleaning. DO NOT use scouring pads. If scrubbing is necessary, use a non-abrasive cleanser or liquid dish soap with a nylon pad or brush.
  4. Air-dry all parts after each use.

Note: DO NOT take apart the pressure release valve or float valve assembly.

Removing & Reinstalling the Silicone Ring

To remove the silicone ring, pull it outward, section by section, from the silicone ring rack. The ring can be installed with either side facing up. To reinstall, press it down into the rack section by section.

After use, remove any food debris from the silicone ring and anti-clog cap.

Keep the silicone ring clean to avoid odour. Washing it in warm, soapy water or in the dishwasher can remove odour. However, it is normal for it to absorb the smell of certain acidic foods. It is recommended to have more than one silicone ring at hand. You can purchase additional silicone rings on ninjakitchen.co.uk

NEVER pull out the silicone ring with excessive force, as this may deform it and the rack and affect the pressure-sealing function. A silicone ring with cracks, cuts, or other damage should be replaced immediately.

Diagram Description: Diagrams show how to remove and reinstall the silicone ring by pulling it from the rack and pressing it back in.

Helpful Tips

  1. For consistent browning, make sure ingredients are arranged in an even layer on the bottom of the cooking pot with no overlapping. If ingredients are overlapping, make sure to shake half way through the set cook time.
  2. For smaller ingredients that could fall through the reversible rack, we recommend first wrapping them in a parchment paper or foil pouch.
  3. When switching from pressure cooking to using the crisping lid it is recommended to empty the pot of any remaining liquid for best crisping results.
  4. Press and hold down the ⬆️ or ⬇️ Time arrows to move faster through Time display.
  5. Use the Keep Warm mode to keep food at a warm, food-safe temperature after cooking. To prevent food from drying out, we recommend keeping the lid closed and using this function just before serving. To reheat food, use the Air Crisping function.
  6. To have your unit build pressure quicker, set it to SEAR/SAUTÉ HIGH. Once ready to pressure cook, press the PRESSURE button and continue as you normally would.
