COOK AND HOLD OPERATION — Model HEC20D Cook and Hold roasts the product in two stages. During First Stage Cooking, the oven temperature is regulated by the Temperature setpoint and the Time setting. After the time counts down to 00:00, Second Stage Cooking begins. During Second Stage Cooking, the heating elements are off as the temperature in the oven declines to the Hold Temperature. The doors should remain closed during Second Stage Cooking. When the Hold temperature is reached, the display flashes HOLD.
PROPER UTENSILS The use of proper utensils can enhance oven operation. Medium- and lightweight pans are recommended since it is more economical to bake with lighter pans. Meats should be roasted in shallow pans deep enough to hold all juices and allow free air circulation. CONSERVING ENERGY • • • • Turn off unused equipment. Adjust menu patterns and cooking/baking schedules for optimum equipment use. Preheat only to required cooking temperature for specific food - not higher.
