PREHEAT FIRST STAGE COOKING SECOND STAGE | HOLDING COOKING (DO NOT OPEN TIME DOORS) PROPER UTENSILS The use of proper utensils can enhance oven operation. Medium and light weight pans allow the product to warm faster. Roast meats in shallow pans deep enough to hold all juices yet allow free air circulation. OPERATING HINTS When using the convection oven for the first time with a particular food, check the degree of doneness periodically before the suggested time has elapsed, to make sure the desired doneness is achieved. Record your temperature and time settings for various products. The convection oven can provide consistent, repeatable results. The convection oven is a bit faster than conventional deck-type ovens; temperature settings are lower and cook times are shorter. Since recipes and foods are subject to many variations and tastes, the guidelines regarding Times and Temperatures in this manual are SUGGESTIONS ONLY. Experiment with your food products to determine the cooking temperatures and times that give you the best results. — 18 — CLEANING —. WARNING: TURN OVEN OFF AND UNPLUG ELECTRICAL CORD BEFORE CLEANING. Clean outside of the oven daily by wiping with a clean damp cloth. Clean porcelain oven interior daily with soap or detergent and water. Rinse thoroughly and wipe dry with a soft clean cloth. Optional Stainless Steel Oven Interior Soap or detergent and water usually handle routine cleaning. Rinse thoroughly, dry with a soft clean cloth. For burned-on foods and grease which resist simple soap and water cleaning, an abrasive cleanser iscouring powder) mixed into a paste may be used. Apply with stainless steel wool or sponge, always rubbing with the "grain." This treatment is equally effective for "heat tint" (slightly darkened areas caused by oxidation). Again, remember to rub in the direction of the polish lines. Rinse with clear water and dry with a soft cloth. — 19 — MAINTENANCE WARNING: TURN OVEN OFF AND UNPLUG POWER SUPPLY CORD BEFORE PERFORMING ANY MAINTENANCE.

It is best not to rotate the product or open the doors during the cooking cycle. Preheat oven to 50°F (10°C) higher than desired cooking temperature. After the oven is loaded, close the door and set thermostat to desired cooking temperature. Make adjustments in the time, temperature and fan speed settings until the desired results are obtained. Adjust only one setting at a time. For example, if the product is too dark on the outside and not done on the inside, it is cooking too fast. Try reducing the temperature by 25°F (-3.8°C). These cooking charts will be helpful in arriving at time, temperature and fan speed settings for products commonly cooked in convection ovens, but since each user's perception of how a particular product should be finished will be different, it may be necessary to make adjustments in the settings until the desired results are obtained. When the desired results are obtained, make a note of the settings used for a particular recipe and product load. For example, if the user typically bakes four 18" x 26" (45 cm x 66 cm) sheet cakes using 5 lb. (2.26 kg) of batter for each cake, that would constitute a typical product load for that recipe. If the size of the load is changed, it may affect the final results. If the user changes either the weight of the cakes being baked, or the number of cakes being baked at a time, it may be necessary to make further adjustments in the time or temperature settings to achieve the desired results. — 922.
