iiINTRODUCTIONSAVE THESE INSTRUCTIONS Grounding InstructionsThis appliance must be grounded. In the event of an electrical short circuit, grounding reduces the risk of electric shock by providing an escape wire for the electric current. This oven is equipped with a cord that has a grounding wire with a grounding plug, which must be plugged into an outlet that is properly installed and grounded. Consult a qualified electrician or serviceman if uncertain about the ability to follow grounding instructions or if doubt exists as to whether the appliance is properly grounded. X use an extension cord. If the power cord is too short, have a qualified electrician or serviceman install an outlet near the appliance. WARNING: Improper grounding can result in risk of electric shock.Power Cord ReplacementIf the power cord is damaged, it must be replaced by the manufacturer, its service agent, or a similarly qualified person.Precautions to Avoid Possible Exposure to Excessive Microwave Energy(a) Do not attempt to operate this oven with the door open since open-door operation can result in harmful exposure to microwave energy. It is important not to defeat or tamper with the safety interlocks.(b) Do not place any object between the oven front face and the door or allow soil or cleaner residue to accumulate on sealing surfaces.(c) Do not operate the oven if it is damaged. It is particularly important that the oven door close properly and that there is no damage to the: (1) Door (bent), (2) hinges and latches (broken or loosened), (3) door seals and sealing surfaces.(d) The oven should not be adjusted or repaired by anyone except properly qualified service personnel.RF Interference ConsiderationsThe Tornado oven generates radio frequency signals. This device has been tested and was determined to be in compliance with applicable portions of FCC part 18 requirements and to the protection require-ments of Council Directive 89/336/EEC on the approximation of the laws of the Member States relating to electromagnetic compatibility at the time of manufacture. However, some equipment with sensitivity to signals below these limits may experience interference.If your equipment experiences interference:Increase the physical separation between this oven and the sensitive equipment.If the sensitive device can be grounded, do so following accepted grounding practices.If battery-powered microphones are being affected, ensure that the batteries are fully charged.Keep sensitive equipment on separate electrical circuits if possible.Route intercom wires, microphone wires, speaker cables, etc. away from the oven. Protective Earth (Ground) Symbol This symbol identifies the terminal which is intended for connecting an external conductor for pro- tection against electric shock in case of a fault, or the terminal of a protective earth (ground) electrode.Equipotential Bonding Symbol This symbol identifies the terminals which, when connected together, bring the various parts of an equipment or of a system to the same potential, not necesarily being the earth (ground) potential, e.g. for local bonding.

3HOW THE TECHNOLOGY WORKS 2: How the Technology WorksTHE TECHNOLOGY BEHIND THE TORNADO The Tornado uses a patented combination of high speed forced air convection, heating, and micro-wave energy to cook food up to 12 times faster than conventional methods. At a very high speed of circulation, a controlled, smoothly flowing field of hot air forms a shroud around the food. This takes place in conjunction with measured, precise bursts of microwave energy, creating a unique set of temperature and moisture control conditions within the food that preserves and enhances flavor. Figure 2 illustrates the five steps of the technology used by the Tornado Oven. These steps, described below, are all computer controlled. 1. The internal heaters transfer energy to the recirculating airflow.2. The recirculating airflow circulates at speeds up to 60 mph (100 km/h) down and around the food item.3. Simultaneously, a bottom radiant heater provides heat transfer to the bottom of the food product.4. The recirculating air passes through a Catalytic Converter where excess grease and odors are combusted and removed.5. Working in parallel with the recirculating airflow and bottom IR element, the microwave system couples microwave energy from the bottom of the cavity evenly into the food items.NOTE: An easy way to understand our cooking is to think of the microwave cooking from the inside out and the airflow cooking from the outside in. The two energy gradients meet and greatly reduce the cook time.How the Technology Works
