Product Components
Familiarize yourself with the parts of your air fryer:
- Main Unit: Houses the heating element and fan.
- Digital Touchscreen Control Panel: For setting time, temperature, and selecting presets.

Setup and First Use
- Unpacking: Remove all packaging materials, stickers, and labels from the appliance.
- Initial Cleaning: Wash the frying basket and any removable accessories in warm, soapy water. Rinse thoroughly and dry completely. Wipe the interior and 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. Ensure there is at least 6 inches (15 cm) of clear space around the back and sides of the appliance for proper ventilation. Do not place it directly against a wall or under cabinets.
- Power Connection: Plug the power cord into a grounded electrical outlet.
- First Use Odor: It is normal for a slight odor to be present during the first few uses as manufacturing residues burn off. This is harmless and will dissipate. To minimize this, you may run the air fryer empty for about 10-15 minutes at 350°F (175°C) before cooking food.
