Setup and First Use
Before using your MegaChef Air Fryer Oven for the first time, follow these steps:
- Unpack: Carefully remove all packaging materials, including any internal packing and protective films.
- Clean Accessories: Wash the bake tray, wire rack, air fry basket, and crumb tray in warm, soapy water. Rinse thoroughly and dry completely.
- Wipe Down: Wipe the interior and exterior of the oven with a damp cloth. Ensure all surfaces are dry before plugging in.
- Placement: Place the oven on a stable, heat-resistant, and level surface. Ensure there is at least 4-6 inches of clearance on all sides and above the oven for proper ventilation. Do not place it directly against a wall or under cabinets.
- Initial Burn-Off: Before cooking food, operate the oven empty for approximately 15 minutes at 400°F (200°C) on the 'Bake' function. This will burn off any manufacturing residues and odors. A slight smoke or odor is normal during this process. Ensure the area is well-ventilated.
- Cool Down: Allow the oven to cool completely after the initial burn-off.
