USING THE OVEN BEFORE USING THE OVEN Read the instructions for each feature and cooking mode in this manual carefully before using the oven. CAUTION • Do not use any type of foil or oven liner to cover the oven bottom. These items can trap heat or melt, resulting in damage to the product and risk of shock, smoke or fire.
WARNING FOOD POISONING HAZARD • Do not let food sit in oven more than one hour before or after cooking. Doing so can result in food poisoning or sickness. • Foods that can easily spoil such as milk, eggs, fish, meat or poultry, should be chilled in the refrigerator first.
USING OVEN RACKS The racks have a turned-up back edge that prevents them from being pulled out of the oven cavity. CAUTION • Replace oven racks before turning the oven on to prevent burns. • Do not cover the racks with aluminum foil, or any other material, or place anything on the bottom of the oven.
PREHEATING Preheating is generally desirable, although not absolutely necessary in all circumstances. • Preheating is necessary for good results when baking cakes, cookies, pastry and breads. • Preheating will help to sear roasts and seal in meat juices. • Place oven racks in their proper position before preheating. •...
Page 28
To Use the Temperature Probe: 1. Insert the probe tip into the food. NOTE: • For meats, the probe tip should be inserted into the center of the thickest part of the meat. Make sure that the probe tip is not into the fat or touching bone.
MAXIMUM & MINIMUM DEFAULT SETTINGS Most cooking modes have minimum and maximum cook time and temperature settings that may be entered into the control. Two short beeps sound if the entry of the temperature or time is out of the range allowed for the feature when START is pressed.
BAKE The Bake mode uses heat from upper and lower elements to cook food. No fan is used to circulate the heat. This mode works best with food placed on a single rack. When using this mode to prepare baked goods such as cakes, cookies and pastries, always preheat the oven first and place food centrally near the middle racks.
BROIL The Broil mode uses intense heat from the upper elements to sear foods. Ideal for toasting, melting cheese, browning and searing surface. Thicker cuts and unevenly shaped pieces of meat, fish and poultry may cook better at lower broiling temperatures. Food should be placed near the upper racks, and should not be cooked for too long on each side of the food.
WARM The Warm mode uses heat from the lower heating element to maintain oven temperature of less than 210°F (99°C). It will keep cooked food warm for serving up to 1 hour after cooking has finished. Cover foods that need to remain moist and do not cover foods that should be crisp.
PROOF The Proof feature uses heat from the lower heating element to maintain a warm environment for rising yeast leavened products before baking. To avoid lowering the oven temperature and lengthening proofing time, do not open the oven door unnecessarily. Check bread products early to avoid over-proofing.
CONVECTION BAKE The Convection Bake mode uses heat from upper and lower elements and hot air movement from the convection fan to enhance cooking efficiency and evenness across multiple racks. Always preheat the oven first. Baking times may be slightly longer for multiple racks than what would be expected for a single rack.
CONVECTION BROIL The Convection Broil mode uses intense heat from the upper elements and air movement from the fan to enhance cooking efficiency and evenness across multiple racks. Ideal for grilling meats, vegetables, and poultry. Cooking times may be slightly longer for multiple racks than what would be expected for a single rack.
CONVECTION ROAST The Convection Roast mode uses heat from both upper and lower elements and hot air movement from the convection fan to enhance cooking efficiency and evenness across multiple racks. Ideal for roasting meats and poultry. Heated air circulates around the food from all sides, sealing in juices and flavors.
CONVECTION CONVERSION (MEATS / BAKED GOODS / OTHERS) When using the Connection Conversion modes, the oven will automatically convert entered regular cooking temperatures to convection cooking temperatures. The cooking temperature will decrease 25°F and the cooking time will decrease 10%. For example, if you enter a regular recipe temperature of 350°F and press START, the display will show the converted temperature of 325°F.
8. Place the food in the oven after preheating. NOTE: • For Meats mode, it is not necessary to preheat the oven. Preheating can cause overcooking. If preheat is required for the recipe, add 15 minutes to the cook time, and place food in the oven at the appropriate time.
Page 39
COOKWARE • The material, finish, and size of cookware affect baking performance. • Dark, coated and dull pans absorb heat more readily than light, shiny pans. Pans that absorb heat more readily can result in a browner, crisper, and thicker crust. If using dark and coated cookware, check food earlier than minimum cook time.

CONVECTION BAKE Convection Bake uses heat from the upper and lower heating elements and air movement from the convection fan to enhance cooking efficiency and evenness across multiple racks. Reduce recipe baking temperatures by 25°F (15°C). • For best results, foods should be cooked uncovered, in low-sided pans to take advantage of the forced air circulation.

Foods recommended for convection bake mode: Appetizers, Biscuits, Cakes, Casseroles, Coffee Beans, Cookies (2 to 4 racks), Cream Puffs, Popovers, Yeast Breads, One-Dish Entrées, Oven Meals (rack positions 3 and 4), and Air Leavened Foods (Soufflés, Meringue, Meringue- Topped Desserts, Angel Food Cakes, Chiffon Cakes).
