OPERATING INSTRUCTIONS OVEN COOKING BEFORE USE: When using the oven for the first time it should be operated for 15-30 minutes at a temperature of about 500°F without cooking anything inside in order to eliminate any moisture and odors from the internal insulation. IMPORTANT: In case of electric power failure, set oven/broiler controls in off position and do not attempt to use oven/broiler until electric power has been restored. TIPS • Use care when opening the oven door.
OPERATING INSTRUCTIONS OVEN FUNCTIONS The oven has 5 functions defined for the following operations: BAKE - Broiler + Bottom heating elements, to be used with oven temperature from 100° to 500°F TURBO - Circular + Bottom heating elements + fan, to be used with oven temperature from 100° to 500°F BROIL - Broiler heating element, to be used with temperature selector at 500°F for broiling CONVECTION BROIL - Broiler heating element + fan, to be used with temperature selector at 500°F for convection broiling
OPERATING INSTRUCTIONS BAKE Preheating Preheat the oven before baking. The oven does not need to be preheated for large pieces of meat or poultry. See your recipe for preheating recommendation. Preheating time depends on the temperature setting and the number of racks in the oven. Tips for Getting the Best Results • Minimize opening the door. • Choose the right size bake ware. • Use the bake ware recommended in the recipe.
OPERATING INSTRUCTIONS COOKING WITH CONVECTION There are many advantages to cooking with convection. In the convection system, a fan in the back of the oven moves heated air evenly around the oven. The moving air provides even heat so foods can be placed on any rack level with consistent results and without having to rotate the pans. Convection also enables cooking simultaneously on multiple racks. Low, shallow bake ware should be used with convection cooking.
OPERATING INSTRUCTIONS CONVECTION BAKE & TURBO (Continued) Preheating Preheat the oven before baking. The oven does not need to be preheated for large pieces of meat or poultry. See your recipe for preheating recommendation. Preheating time depends on the temperature setting and the number of racks in the oven.
