Key Features

Setup

Before first use, please follow these steps to ensure safe and optimal performance of your Oster® Compact Countertop Oven With Air Fryer.

  1. Unpacking: Carefully remove all packaging materials, including any internal packing and protective films. Retain packaging for future storage or transport if needed.
  2. Placement: Place the oven on a stable, flat, heat-resistant surface. Ensure there is adequate clearance (at least 4-6 inches) on all sides and above the oven for proper ventilation. Do not place it near flammable materials or under cabinets that are not heat-resistant.
  3. Initial Cleaning: Wash the removable baking pan, air fry basket, and wire rack in warm, soapy water. Rinse thoroughly and dry completely. Wipe the interior and exterior of the oven with a damp cloth. Do not immerse the main unit in water.
  4. First Use Burn-Off: Before cooking food, operate the oven empty for approximately 15 minutes at 450°F (232°C) on the "Bake" setting. This will burn off any manufacturing oils and eliminate initial odors. A slight odor or smoke is normal during this process. Ensure the area is well-ventilated.
  5. Power Connection: Plug the power cord into a grounded 120V AC electrical outlet.
