Using the Atosa MGF8453GR refrigerated chef base is easy. First, make sure it's plugged into a proper 115 - Volt outlet. You can adjust the temperature using the digital controller to your desired setting between 33 and 38°F. Place your food items like hamburgers, toppings, or panini fixings in the spacious drawers. When you're done using a drawer, just let go, and it will close automatically. For maintenance, regularly clean the interior and exterior with a mild detergent and a soft cloth. Check the magnetic gaskets on the drawers to ensure they're sealing properly. Keep the area around the chef base clean and well - ventilated. When moving the unit, use the swivel casters. Remember to lock the brakes on two of the wheels when you've positioned it to keep it stable. Also, make sure to follow all safety guidelines provided in the product manual.
