Using your Nella commercial rice warmer is easy. First, make sure it's plugged into a 110V, 60 Hz, 1 - phase power source with the NEMA 5 - 15P plug. Then, add your cooked rice to the non - stick aluminum inner pot. The warmer will automatically maintain a temperature between 71°C and 75°C to keep your rice warm and fresh for up to 48 hours. When you're done using it, remove the inner pot and clean it with warm, soapy water. Don't use abrasive cleaners as they can damage the non - stick coating. Keep the exterior of the warmer clean by wiping it with a damp cloth. Also, make sure to place it on a stable, flat surface away from heat sources and water. Always follow all safety instructions provided with the product.
