3. Setup and First Use
Before First Use:
- Remove all packaging materials, stickers, and labels from the appliance.
- Thoroughly clean the air fryer's components (basket, pan, grill rack) in warm water with mild soap for 10-15 minutes. Use a soft sponge to clean the components, the drawer, and the inside of the air fryer. Rinse and dry completely.
- Wipe the exterior of the appliance with a damp cloth.
- Place the air fryer on a stable, level, and heat-resistant surface, ensuring adequate air circulation around the unit.
Removing Plastic Smell (Optional but Recommended):
Some new appliances may emit a slight odor during initial use. To minimize this:
- After cleaning, run the empty air fryer at 400°F (200°C) for a few minutes. This can help dissipate any manufacturing odors.
- If the smell persists, place 1 tablespoon of distilled vinegar and 1 tablespoon of lemon juice in a small, oven-safe dish inside the air fryer basket. Run the air fryer for a few minutes. Allow it to cool for 10 minutes, then repeat if necessary. To remove any residual vinegar/lemon smell, place a dish containing only water in the air fryer and run it again.
4. Operating Instructions
Basic Operation:
- Plug the power cord into a grounded wall outlet.
- Pull out the fry basket from the air fryer.
