There is no need to select moisture levels. Foods do not dry out. Flavors are retained with no transfer of flavors when mixing product loads. Due to the automatic steam adjustment, the door can be opened at any time during a cooking operation. Be certain to observe the safety war ning when opening the oven door. The Combination mode is particularly efficient when used for baking, broiling, grilling, stewing, braising, and roasting. When using the Combination mode, cooking temperatures can be reduced 10- to 20-percent below the temperatures used for conventional cooking methods. Cooking time will be reduced approximately 40-percent when cooking at the same temperature used for convection oven cooking and up to 50- to 60-percent less time when cooking at the same temperature used for a conventional oven. Food browning in the Combither m begins at a cooking temperature of approximately 248°F (120°C). A higher cooking temperature results in heavier browning but also results in greater product weight loss. To achieve additional browning use the Moisture Vent Key or set Gold-n-Brown into the product procedure. Gold-n-Brown is particularly useful for adding color to high moisture products such as chicken and other poultry items or for additional browning of full loads and other moist products. The Combination mode provides even browning without the necessity to tur n the pans. For more even cooking, do not cook in pans deeper than 4-inches (100mm).

The Convection mode works best with foods containing little moisture or for very moist food which require a dryer finished product. For baking, preheat the Combither m at a temperature of 36°F to 54°F (20°C to 30°C) above the baking temperature required. Once preheated, reset the temperature as required. A higher cooking temperature results in heavier browning but also results in greater product weight loss. To achieve additional browning use the Moisture Vent Key or set the Browning Feature into the product procedure. To prevent the sur face of food from excessive drying, the fan will not engage if the inter nal oven temperature is above 212°F (100°C) and the set oven temperature is below 212°F (100°C).

Product density (compactness), thickness, quantity of product on each plate, and quantity of plates all relate to the length of time necessary to reheat. Again, experience is the best method to determine reheating time. Once the time has been determined and recorded for a specific meal, the results will be consistent for future reheating times. HELPFUL HINTS FOR REHEATING ON THE PLATE • ALL FOOD COMPONENTS ON THE PLATE SHOULD BE OF SIMILAR DENSITIES. • ALL FOOD COMPONENTS ON THE PLATE SHOULD BE SIMILAR IN THICKNESS. • ARRANGE ALL FOOD COMPONENTS EVENLY ON THE PLATE. • AVOID EXCESSIVE OVERLAPPING OF PRODUCT. • SAUCES MUST BE HEATED AND ADDED TO PRODUCT AFTER REHEATING. • A MIXED VARIETY OF MEALS CAN BE REHEATED AT THE SAME TIME. • À LA CARTE RETHERMALIZATION required. Follow internal temperature requirements À la carte rethermalization is designed to take a single plate from a refrigerated temperature to serving temperature for immediate service. Plates are prepared in advance, covered, and refrigerated. Preheat the Combitherm oven. Remove plate from refrigeration and place in the oven at 275°F (135°C) for an uncovered plate or 300°F (150°C) for a covered plate. Plates with meat components will take more time than plates containing all vegetable components. Follow internal temperature requirements for reheating and allow for override time. After reheating, remove the plate from the oven, add any sauces, garnish, and serve. This process can be repeated as required. for reheating and allow for override time. Remove For the most efficient continuous service, it is suggested that the Combitherm oven be dedicated to the rethermalization process during serving hours. • BANQUET RETHERMALIZATION Banquet rethermalization is designed for high volume, full or partial load (multiple plate) reheating. For maximum efficiency, it is essential that volume rethermalization be used in conjunction with the utilization of holding cabinets to keep rethermalized food at proper temperatures. Plates are assembled in advance, covered, and refrigerated or loaded on the roll-in cart and refrigerated. Preheat the Combitherm oven at 275°F (135°C) for uncovered plates or 300°F (150°C) for covered plates. Remove plates or the roll-in cart from refrigeration, load in the oven and set timer as the plates or roll-in cart from the Combitherm and roll into the companion holding cabinet. Relocate the holding cabinet to the banquet service area. • RETHERMALIZING PREFABRICATED AND VACUUM-PACKED FROZEN FOODS For bulk product rethermalization, completely defrost product bags in walk-in cooler. DO NOT REMOVE PRODUCT FROM THE BAG. Load thawed bags in preheated oven and rethermalize in the Low Temperature Steam mode until the required internal temperature is reached. Place rethermalized bags in a preheated holding cabinet set at 140° to 165°F (60° to 74°C) until ready for service. For large volume on-the-plate regeneration, defrost bags in walk-in cooler. Open bags and plate per menu requirements in a ( MAXIMUM ) 55°F (13°C) refrigerated room. Cover plates, place on Alto-Shaam roll-in cart (trolley), and roll into Combitherm oven preheated at 275°F (135°C). Regenerate in the Convection mode for 3 to 5 minutes. Switch to the Retherm mode for an additional 3 minutes or more if required. Transfer full trolley to a preheated holding cabinet set at 160°F (71°C) until ready for service. In the case of meat cooked to rare, set the cabinet at 140°F (60°C). PLATE COVERS MUST BE USED FOR ON-THE-PLATE REGENERATION.

SECTION 2 – PREVENTIVE MAINTENANCE • COMBITHERM ELECTRIC TECHNICAL SERVICE MANUAL • 43 PREVENTIVE MAINTENANCE P R O T E C T I N G S TA I N L E S S S T E E L S U R FA C E S CLEANING AGENTS It is important to guard against corrosion in the care of stainless steel surfaces. Harsh, corrosive, or inappropriate chemicals can completely destroy the protective surface layer of stainless steel. Abrasive pads, steel wool, or metal implements will abrade surfaces causing damage to this protective coating and will eventually result in areas of corrosion. Even water, particularly hard water that contains high to moderate concentrations of chloride, will cause oxidation and pitting that result in rust and corrosion. In addition, many acidic foods spilled and left to remain on metal surfaces are contributing factors that will corrode surfaces. Proper cleaning agents, materials, and methods are vital to maintaining the appearance and life of this appliance. Spilled foods should be removed and the area wiped as soon as possible but at the very least, a minimum of once a day. Always thoroughly rinse surfaces after using a cleaning agent and wipe standing water as quickly as possible after rinsing. USE AUTHORIZED COMBITHERM LIQUID OVEN CLEANER ONLY Cleaning agents must be chloride-free compounds and must not contain quaternary salts. Never use hydrochloric acid (muriatic acid) on stainless steel surfaces. Unauthorized cleaning agents may discolor or harm interior surfaces of the oven. Read and understand label and material safety data sheet before using the oven cleaner. C L E A N I N G M AT E R I A L S The cleaning function can usually be accomplished with the proper cleaning agent and a soft, clean cloth. When more aggressive methods must be employed, use a non-abrasive scouring pad on difficult areas and make certain to scrub with the visible grain of surface metal to avoid surface scratches. Never use wire brushes, metal scouring pads, or scrapers to remove food residue. TO PROTECT STAINLESS STEEL SURFACES, COMPLETELY AVOID THE USE OF ABRASIVE CLEANING COMPOUNDS, CHLORIDE BASED CLEANERS, OR CLEANERS CONTAINING QUATERNARY SALTS. NEVER USE HYDROCHLORIC ACID (MURIATIC ACID) ON STAINLESS STEEL. NEVER USE WIRE BRUSHES, METAL SCOURING PADS OR SCRAPERS.
