Introduction Oven Description and Specifications Cooking in a convection oven differs from cooking in a conventional deck or range oven since heated air is constantly recirculated over the product by a fan in an enclosed chamber. The moving air continually strips away the layer of cool air surrounding the product, quickly allowing the heat to penetrate. The result is a high quality product, cooked at a lower temperature in a shorter amount of time.

Operation General Guidelines for Operating Personnel COOK TIMES AND TEMPERATURES OPERATING TIPS Preheating the oven Pans and Racks Always preheat the oven before baking or roasting. We recommend preheating 50_F (10_C) above the cook temperature to offset the drop in temperature when the doors are opened and cold product is loaded into the oven. Set the thermostat to the cook temperature after the product is loaded. Product or pan height determines how many racks are used.
Maintenance Cleaning and Preventative Maintenance DAILY CLEANING 1. Turn the oven to COOL DOWN. NOTE: The doors may be opened to speed the cooling process. 5. Wipe around the fan with a damp towel. 6. Soak racks, supports and baffle in a solution of non-toxic, non-caustic, food safe, commercial oven cleaner. Allow to soak overnight if necessary. 7. Reinstall parts. Cleaning the exterior Clean temperature probe 1. Saturate a cloth with a mild soap and water mixture. Wipe the oven when it is cold. 2.
