The oven will automatically stop cooking. To continue cooking, you simply close the door. If you wish to stop cooking during the cooking simply, turn the timer knob the point OFF. Cooking can be reset at any time during the cooking cycle by only turning the timer knob. Do not let the timer continue to operate after removing food. 7 COOKING INSTRUCTIONS Utensils should be checked to ensure that they are suitable for use in microwave ovens. UTENSILS TEST Place the utensil in question next to a glass measure filled with water, in the microwave oven. Microwave at high power for 1-2 minutes. If the water heats up, but the utensil remains cool, the utensil is microwave-safe. However if the utensil becomes warm, microwaves are being absorbed by the utensil and it should not be in the microwave oven. You probably have many items on hand in your kitchen right now that can be used as cooking equipment in your microwave oven. Read through the following checklist. COOKING UTENSILS Recommended Use Glass and glass-ceramic bowls and Dishes - Use for heating or cooking. Microwave browning dish - Use to brown the exterior of small items such as steaks, chops, or pancakes. Follow the directions provided with you browning dish. Microwaveable plastic wrap - Use to retain steam. Leave a small opening for some steam to escape and avoid placing it directly on the food. Wax paper - Use as a cover to prevent spattering. Paper towels, and napkins - Use for short term heating and covering; they absorb excess moisture and prevent spattering. Do not use recycled paper towels, which may contain metal and can eatch fire. Thermometers - Use only those labeled Microwave Safe and follow all directions. Check the food in several places. Conventional thermometers may be used once the food has been removed from the oven. Microwave cling film, microwave roasting bags - Microwave cling film and bags must be vented for steam to escape, pierce in 4~5 places. Do not use plastic or metal ties as they may melt or catch fire due to electrical arcing. Limited Use Aluminum foil - Use narrow strips of foil to prevent overcooking of exposed areas. Using too much toil can damage your oven, so be careful. Ceramic, porcelain, and stoneware - Use these if they are labeled Microwave Safe. If they are not labeled, test them to make sure they can be used safely. Never use dishes with metalic trim. Plastic - Use only if labeled Microwave Safe. Other plastics can melt. Thin plastic, paper, straw and wooden containers - Always attend the oven closely. Look at the oven from time to time when cooking or reheating food in disposable containers of plastic, paper or other combustible material. Only use for warming food. Pay special attention as over-heating may cause a fire in your oven. Not Recommended Glass jars and bottles - Regular glass is too thin to be used in a microwave, and can shatter. Paper bags - These are a fire hazard, except for popcorn bags that are designed for microwave use. Styrofoam plates and cups - These can melt and leave an unhealthy residue on food. Plastic storage and food containers - Containers such as margarine tubs can melt in the microwave. Metal utensils - These can damage your oven. Remove all metal before cooking. 8 CARE OF YOUR MICROWAVE OVEN 1 2 Turn the oven off before cleaning. Keep the inside of the oven clean. When food spatters or spilled liquids adhere to oven walls, plate tray, stirrer cover and inlet cover wipe with a damp cloth. Mild detergent may be used if the oven gets very dirty. The use of harsh detergent or abrasives is not recommended. 3 4 5 The outside oven surface should be cleaned with soap and water, rinsed and dried with a soft cloth. To prevent damage to the operating parts inside the oven, water should not be allowed to seep into the ventilation openings. If the Control Panel becomes wet, clean with a soft, dry cloth. Do not use harsh detergents or abrasives on Control Panel. If steam accumulates inside or around the outside of the oven door, wipe with a soft cloth. This may occur when the microwave oven is operated under high humidity conditions and in no way indicates malfunction of the unit. IMPORTANT CAUTIONS 1. Do not operate after removed food. 2. Do not operate the oven without stirrer cover in place. 3. Do not remove the stirrer cover and plate tray. 9 MICROWAVING PRINCIPLES Microwave energy has been used in this country to cook and reheat food since early experiments with RADAR in World War ll. Microwaves are present in the atmosphere all the time, both naturally and manmade sources. Manmade sources include radar, radio, television, telecommunication links and car phones. HOW MICROWAVES COOK FOOD TRANSMISSION L In a microwave oven, electricity is converted into microwave by the MAGNETRON. Then they pass through the cooking containers to be absorbed by the water molecules in the food, all foods contain water to a more or lesser extent. L REFLECTION L ABSORPTION The microwaves bounce off the metal walls and the metal door screen. The microwaves cause the water molecules to vibrate which causes FRICTION, i.e. HEAT. This heat then cooks the food. Microwaves are also attracted to fat and sugar particles, and foods high in these will cook more quickly. Microwaves can only penetrate to a depth of 11/2 - 2 inches(4-5cm) and as heat spreads through the food by conduction, just as in a traditional oven, the food cooks from the outside inwards.

= 3840 ml (UK 4500 ml) STARTING TEMPERATURE The colder the food, the longer it takes to heat up. Food from a fridge takes longer to reheat than food at room temperature. LIQUIDS All liquids must be stirred before and during heating. Water especially must be stirred before and during heating, to avoid eruption. Do not heat liquids that have previously been boiled. DO NOT OVERHEAT. TURNING & STIRRING Some foods require stirring during cooking. Meat and poultry should be turned after half the cooking time. ARRANGING Individual foods e.g. chicken portions or chops, should be placed on a dish so that the thicker parts are towards the outside. QUANTITY Small quantities cook faster than large quantities, also small meals will reheat more quickly than large portions. PIERCING The skin or membrane on some foods will cause steam to build up during cooking. These foods must be pierced or a strip of skin should be peeled off before cooking to allow the steam to escape. Eggs, potatoes, apples, sausages etc, will all need to be pierced before cooking. DO NOT ATTEMPT TO BOIL EGGS IN THEIR SHELLS. COVERING Cover foods with microwave cling film or a lid. Cover fish, vegetables, casseroles, soups. Do not cover cakes, sauces, jacket potatoes or pastry items. COOKING TECHNIQUES STANDING TIME Dense foods e.g. meat, jacket potatoes and cakes, require standing time(inside or outside of the oven) after cooking, to allow heat to finish conducting to cook the center completely. Wrap meat joints and jacket potatoes in aluminium foil while standing. Meat joints need approx. 10-15 minutes, jacket potatoes 5 minutes. Other foods such as plated meal, vegetables, fish etc require 2-5 minutes standing. After defrosting food, standing time should also be allowed. If food is not cooked after standing time, return to the oven and cook for additional time. MOISTURE CONTENT Many fresh foods e.g. vegetables and fruit, vary in their moisture content throughout the season, particularly jacket potatoes. For this reason cooking times may have to be adjusted. Dry ingredients e.g. rice, pasta, can dry out during storage so cooking times may differ. DENSITY Porous airy foods heat more quickly than dense heavy foods. CLING FILM Cling film helps keep the food moist and the trapped steam assists in speeding up cooking times. Pierce before cooking to allow excess steam to escape. Always take care when removing cling film from a dish as the build-up of steam will be very hot. SHAPE Even shapes cook evenly. Food cooks better by microwave when in a round container rather than square. SPACING Foods cook more quickly and evenly if spaced apart. NEVER pile foods on top of each other. 11 USE YOUR MICROWAVE OVEN SAFELY General Use Do not attempt to defeat or tamper with safety interlocks. Do not place any object between the oven front frame and the door or allow residue to build up on sealing surfaces. Wipe with a mild detergent, rinse and dry. Never use abrasive powders or pads. Do not subject the oven door to strain or weight such as a child hanging on an open door. This could cause the oven to fall forward resulting in injury to you and damage to the oven. Do not operate the oven if door seals or sealing surfaces are damaged; or if door is bent; or if hinges are loose or broken. Do not operate the oven empty. This will damage the oven. Do not attempt to dry clothes, newspapers or other materials in the oven. They may catch on fire. Do not use recycled paper products as they may contain impurities which may cause sparks or fires. Do not hit or strike the control panel with hard objects. This can damage the oven. Food Never use your microwave oven for home canning. The oven is not designed for proper home canning. Improperly canned food may spoil and be dangerous to consume. Always use the minimum recipe cooking time. It is better to undercook rather than overcook foods. Undercooked foods can be returned to the oven for more cooking. If food is overcooked, nothing can be done. Heat small quantities of food or foods with low moisture carefully. These can quickly dry out, burn or catch on fire. Do not heat eggs in the shell. Pressure may build up and eggs can explode. Potatoes, apples, egg yolks and sausages are examples of food with non-porous skins. These must be pierced before cooking to prevent bursting. Do not attempt to deep fat fry in your microwave oven. Always stir liquids before heating. Heated liquids can erupt, if not mixed with air. Do not leave the oven unattended while popping corn. Do not pop corn in a paper bag unless it is the commercially prepared Microwave Popcorn product. The kernels can overheat and ignite a brown paper bag. Do not put packaged Microwave Popcorn bags directly on the oven tray. Place the package on a microwave safe glass or ceramic plate to avoid overheating and cracking the oven tray. Do not exceed the Microwave Popcorn manufacturers' suggested popping time. Longer popping does not yield more popcorn but it can result in scorch, burn of fire. Remember, the Popcorn bag and tray can be too hot to handle. Remove with caution and use pot holders. ARCING If you see arcing, open the door and correct the problem. Arcing is the microwave term for sparks in the oven. Arcing is caused by:

Metal or foil touching the side of the oven. Foil not molded to food (upturned edges act like antennas). Metal, such as twist-ties, poultry pins, or gold rimmed dishes, in the microwave. Recycled paper towels containing small metal pieces being used in the microwave. 12 COMMERCIAL MICROWAVE OVEN COOKING GUIDE Weight 3.5oz 1:30 2ea 4:50 2cups 4:50

QUESTIONS AND ANSWERS

* Q : I accidentally ran my microwave oven without any food in it. Is it damaged?

* A : Running the oven empty for a short time will not damage the oven. However, it is not recommended.

* Q : Can the oven be used with the glass tray or roller guide removed?

* A : No. Both the glass tray and roller guide must always be used in the oven before cooking.

* Q : Can I open the door when the oven is operating?

* A : The door can be opened anytime during the cooking operation. Then microwave energy will be instantly switched off and the time setting will maintain until the door is closed and START is touched.

* Q : Why do I have moisture in my microwave oven after cooking?

* A : The moisture on the side of your microwave oven is normal. It is caused by steam form cooking food heating the cool oven surface.

* Q : Dose microwave energy pass through the viewing screen in the door?

* A : No. The metal screen bounces back the energy to the oven cavity. The holes are made to allow light to pass through. They do not let microwave energy pass through.

* Q : Why do eggs sometimes pop?

* A : When baking or poaching eggs, the yolk may pop due to steam build-up inside the yolk membrane. To prevent this, simply pierce the yolk with a toothpick before cooking. Never cook eggs without piercing their shells. 14 QUESTIONS AND ANSWERS (continued)

* Q : Why is standing time recommended after the cooking operation has been completed?

* A : Standing time is very important. With microwave cooking, the heat is in the food, not in the oven. Many foods build up enough internal heat to allow the cooking process to continue, even after the food is removed from the oven. Standing time for joints of meat, large vegetables and cakes allows the inside to cook completely, without overcooking the outside.

* Q : What does standing time mean?

* A : Standing time means that food should be removed from the oven and covered for additional time to allow it to finish cooking. This frees the oven for other cooking.

* Q : Why does my oven not always cook as fast as the microwave cooking guide says?

* A : Check your cooking guide again, to make sure youve followed directions exactly ; and to see what might cause variations in cooking time. Cooking guide times and heat settings are suggestions, to help prevent over-cooking... the most common problem in getting used to a microwave oven. Variations in the size, shape and weights and dimensions could require longer cooking time. Use your own judgement along with the cooking guide suggestions to check whether the food has been properly cooked just as you would do with a conventional cooker.

* Q : Will the microwave oven be damaged if it operates while empty?

* A : Yes. Never run it empty.

* Q : Can I operate my microwave oven without the turntable or turn the turntable over to hold a large dish?

* A : No. If you remove or turn over the turntable, you will get poor cooking results. Dishes used in your oven must fit on the turntable.

* Q : Is it normal for the turntable to turn in either direction?

* A : Yes. The turntable rotates clockwise or counterclockwise, depending on the rotation of the motor when the cooking cycle begins.

* Q : Can I pop popcorn in my microwave oven? How do I get the best results?

* A : Yes. Pop packaged microwave popcorn following manufactures guidelines or use the preset POPCORN pad. Do not use regular paper bags. Use the listening test by stopping the oven as soon as the popping slows to a pop every 1 or 2 seconds. Do not repop unpopped kernels. Do not pop popcorn in glass cookware. 15 Warranty Application New, unused Turbo Air Commercial microwave ovens purchased in the United States of America are warranted against manufacturing defects in materials and workmanship as follows:

(1) Primary interlock switch When the door is closed, the hook locks the oven door. If the door is not closed properly, the oven will not operate. When the door is closed, the hook pushes the button of the microswitch. Then the button of the primary interlock switch bring it under ON condition.

(2) Secondary interlock switch and interlock monitor switch When the door is closed, the hook pushes the lock lever downward. The lock lever presses the button of the interlock monitor switch to bring it under NO condition and presses the button of the secondary interlock switch to bring it under ON condition. ADJUSTMENT :

Interlock monitor switch When the door is closed, the interlock monitor switch should be changed (NO condition) before other switches are closed. When the door is opened, the interlock monitor switch should be changed (NC condition) after other switches are opened.

(3) Adjustment steps a) Loosen the one mounting screw. b) Adjust interlock switch assembly position. c) Make sure that lock lever moves smoothly after adjustment is completed. d) Tighten completely two mounting screws. NOTE :

Microwave emission test should be performed after adjusting interlock mechanism. If the microwave emission exceed 4mW/cm2, readjust interlock mechanism. 15 TROUBLE SHOOTING GUIDE Following the procedure below to check if the oven is defective or not. 1. Check grounding before trouble checking. 2. Be careful of the high voltage circuit. 3. Discharge the high voltage capacitor. 4. When checking the continuity of the switches, fuse or high voltage transformer, disconnect one lead wire from these parts and check continuity with the AC plug removed. To do otherwise may result in a false reading or damage to your meter.

(TROUBLE 1) Oven does not operate at all ; any inputs can not be accepted. Does the fan motor work when you shut the door and turn the timer?

NO Does the fuse blow?

YES Check continuity of interlock monitor switch with door shut. Continuity Replace primary, secondary interlock switch and interlock monitor switch. NO NO Replace fuse and check continuity of both interlock switch's contact and monitor switch's contact with door partially open until monitor switch contact. Both continuity Disconnect one side of the lead wire connected from transformer to the high voltage capacitor, and operate oven. NO Replace primary, secondary interlock switch and interlock monitor switch. Normal Replace high voltage capacitor. Fuse again Replace high voltage transformer If outlet has proper voltage, check continuity of power supply cord. NO Continuity Replace power supply cord. 16 Does the fan motor work when you shut the door and turn the timer?

YES Does the oven lamp light?

Does the turntable turn?

NO YES NO Continuity If microwave do not oscillate, check continuity of filament of magnetron. Poor continuity Replace or repair oven lamp, turntable motor. Normal reading should be approx. 0 Check continuity filament tap (3.3V) of high voltage. Continuity Check continuity filament tap (3.3V) of high voltage. Continuity No Continuity Replace high Voltage transformer Continuity in the reverse direction.

NO Continuity Good Replace high voltage transformer. Replace magnetron 17 MEASUREMENT AND TEST 1. MEASUREMENT OF THE MICROWAVE POWER OUTPUT Microwave output power can be checked by indirectly measuring the temperature rise of a certain amount of water exposed to the microwave as directed below. PROCEDURE 1. Microwave power output measurement is made with the microwave oven supplied at rated voltage and operated at its maximum microwave power setting with a load of 10005cc of potable water. 2. The water is contained in a cylindrical borosilicate glass vessel having a maximum material thickness of 3 mm and an outside diameter of approxi-

mately 190 mm. 3. The oven and the empty vessel are at ambient temperature prior to the start of the test. The initial temperature of the water is 102C (503.6F) It is measured immediately before the water is added to the vessel. After addition of the water to the vessel, the load is immediately placed on the center of the shelf, which is in the lowest normal position. 4. Microwave power is switched on. 5. Heating time should be exactly A seconds. (Refer to table as following) Heating time is measured while the microwave generator is operating at full power. The filament heat-up time for magnetron is not included. 6. The initial and final temperature of water is selected so that the maximum difference between the ambient and final water temperature is 5K. 7. The microwave power output P in watts is calculated from the following formula :

P=4187 X LLT/t LLT is difference between initial and final temperature. t is the heating time. The power measured should be B (Refer to SPECIFICATIONS)W10.0%. CAUTION :

1. Water load should be measured exactly to 1 liters. 2. Input power voltage should be exactly specified voltage(Refer to SPECIFICATIONS). 3. Ambient temperature should be 202C(683.6F) Heating time for power output:

A(second) B(W) 70 600 64 650 60 700 56 750 52 800 49 850 47 900 44 950 42 40 38 1000 1050 1100 18 2. MICROWAVE RADIATION TEST CAUTION :

1. Make sure to check the microwave leakage before and after repair of adjustment. 2. Always start measuring of an unknown field to assure safety for operating personnel from microwave energy. 3. Do not place your hands into any suspected microwave radiation field unless the safe density level is known. 4. Care should be taken not to place the eyes in direct line with the source of microwave energy. 5. Slowly approach the unit under test until the radiometer reads an appreciable microwave leakage from the unit under the test. PROCEDURES 1. Prepare Microwave Energy Survey Meter, 600cc glass beaker, and glass thermometer 100C(212F). 2. Pour 275cc15cc of tap water initially at 205C(689F) in the 600cc glass beaker with an inside diameter of approx. 95mm(3.5in.). 3. Place it at the center of the tray and set it in a cavity. 4. Close the door and operate the oven. 5. Measure the leakage by using Microwave Energy Survey Meter with dual ranges, set to 2450MHz. 1) Measured radiation leakage must not exceed the value prescribed below. Leakage for a fully assembled oven with door normally closed must be less than 4mW/cm2. 2) When measuring the leakage, always use the 5cm(2in.) space cone with probe. Hold the probe perpendicular to the cabinet and door. Place the space cone of the probe on the door, cabinet, door seem, door viewing screen, the exhaust air vents and the suction air vents. 3) Measuring should be in a counter-clockwise direction at a rate of 1 in./sec. If the leakage of the cabinet door seem is unknown, move the probe more slowly. 4) When measuring near a corner of the door, keep the probe perpendicular to the areas making sure the probe end at the base of the cone does not get closer than 2 in. from any metal. If it does not, erroneous reading may result. 19 3. COMPONENT TEST PROCEDURE High voltage is present at the high voltage terminal of the high voltage transformer during any cooking cycle. It is neither necessary nor advisable to attempt measurement of the high voltage. Before touching any oven components or wiring, always unplug the oven from its power source and discharge the capacitor. 1. High voltage transformer

(1) Remove connections from the transformer terminals and check continuity.

(2) Normal readings should be as follows:

Secondary winding ...................Approx. 11010%

Filament winding....................................Approx. 0 Primary winding .....................................Approx. 1 2. High voltage capacitor

(1) Check continuity of capacitor with meter on the highest OHM scale.

(2) A normal capacitor will show continuity for a short time, and then indicate 10M once the capacitor is charged.

(3) A shorted capacitor will show continuous continuity.

(4) An open capacitor will show constant 10M.

(5) Resistance between each terminal and chassis should be infinite. 3. High voltage diode

(1) Isolate the diode from the circuit by disconnecting the leads.

(2) With the ohmmeter set on the highest resistance scale measure the resistance across the diode terminals. Reverse the meter leads and again observe the resistance reading. Meter with 6V, 9V or higher voltage batteries should be used to check the front-back resistance of the diode, oth-

erwise an infinite resistance may be read in both directions. A normal diodes resistance will be infinite in one direction and several hundred K in the other direction. 4. Magnetron For complete magnetron diagnosis, refer to Measurement of the Microwave Power Output. Continuity checks can only indicate and open filament or a shorted magnetron. To diagnose for an open filament or a shorted magnetron.

(1) Isolate magnetron from the circuit by disconnecting the leads.

(2) A continuity check across magnetron filament terminals should indicate 0.1 or less.

(3) A continuity check between each filament terminal and magnetron case should read open. 5. Fuse If the fuse in the primary and monitor switch circuit is blown when the door is opened, check the primary and monitor switch before replacing the blown fuse. In case the fuse is blown by an improper switch operation, replace the defective switch and fuse at the same time. Replace just the fuse if the switches operate normally. 20 WIRING DIAGRAM 21 EXPLODED VIEW AND PARTS LIST 1. DOOR ASSEMBLY Refer to Disassembly and assembly. 2.
