Setup
- Unpack: Carefully remove all packaging materials and any promotional labels from the air fryer.
- Clean: Wash the removable basket and cooking rack with hot soapy water, rinse thoroughly, and dry completely. Wipe the exterior of the main unit with a damp cloth. Do not immerse the main unit in water.
- Placement: Place the air fryer on a stable, heat-resistant, and level surface, away from walls or other appliances to allow for proper air circulation. Ensure there is at least 10 cm (4 inches) of space around the back and sides, and above the appliance.
- Initial Run (Optional but Recommended): Before first use, it is recommended to run the air fryer empty for about 10-15 minutes at 200°C (400°F) to burn off any manufacturing residues. A slight odor may be present, which is normal. Ensure the area is well-ventilated.
Operating Instructions
General Operation:
- Prepare Food: Place your ingredients into the air fryer basket. Do not overfill the basket to ensure even cooking. For best results, food should not exceed 3/4 of the basket capacity.
- Insert Basket: Slide the basket back into the main unit until it clicks securely into place.
- Set Temperature: Turn the temperature control knob to your desired cooking temperature (100°F - 400°F / 38°C - 200°C).
- Set Timer: Turn the timer control knob to the desired cooking time (up to 30 minutes). The air fryer will start heating immediately.
- Cooking Process: The indicator light will illuminate, and the fan will start. During cooking, you may pull out the basket to shake or flip food for even results. The air fryer will pause when the basket is removed and resume when reinserted.
- Automatic Shut-off: The air fryer will automatically shut off and emit an audible signal when the timer reaches zero.
- Remove Food: Carefully pull out the basket using the handle. Use tongs to remove cooked food. Be cautious of hot steam.
- Cool Down: Allow the appliance to cool down completely before cleaning or storing.

Preheating:
For optimal results, especially for items that benefit from a quick crisp, preheating is recommended. Set the temperature and timer for 3-5 minutes without food in the basket. The air fryer heats up quickly due to its 1400-watt element and heat circulation technology.
