MICROWAVE OVEN I NSTRUCTION MANUAL Model: XB2831T Please read this booklet carefully before fixing and using, and save it for future reference. Zhongshan Donlim Weili Electrical Appliances Co., Ltd. ADDRESS: Fusha Industrial Park, Fusha Town, Zhongshan City, Guangdong Province 1 OPERAITON THEORY OF MICROWAVE OVEN 1.Microwave is a kind of high frequency electromagnetic wave, which is commonly distributed in the nature. But the existing form of microwave is dispersed so that it cannot be collected together for heating purpose. The key component of magnetron of microwave oven will transform the energy of electricity to microwave and huge energy of microwave field is established under the closed cavity. So the molecule of food is caused to vibrate at very high speed and the friction heat produced will cook the food in a fast way. 2. There is 3 properties of microwave, that is a) Absorbability: the microwave can cause the excess vibration of molecule of various food so as to obtain the heating purpose. But the infiltration ability is largely depend on the size, thickness and properties of the food. b) Penetrability: microwave can penetrate through ceramics, glass, temperature-resistant plastics. It is required to use the containers whose material have good microwave penetrability to achieve best heating result. See the below utensils guide. c) Reflectivity: microwave would be reflected by the metal wall of interior cavity so as to establish an even magnetic field, thus can prevent the overheating of partial area. NSTALLATION OF MICROWAVE OVEN 1) To ensure sufficient ventilation, the distance from the back of microwave to the wall should be above10cm, the side to the wall above 5cm, the top to the ceiling above 20 cm. 2) Do not place any objects on the top of microwave oven. 3) Keep the microwave oven far from the TV, Radio or antenna as picture disturbance or noise may occur. 4) Keep the plug accessible to the socket. 5)This is designed as a freestanding style and should not be placed in a cabinet. UTENSILS GUIDELINE It is strongly recommended to use the containers which are suitable and safe for microwave cooking. Generally speaking, the containers which are made of heat-resistant ceramic, glass or plastic are suitable for microwave cooking. Never use the metal containers for microwave cooking and combination cooking as spark is likely to occur. You can take the reference of below table. Material of container Microwave Notes Ceramic Yes Never use the ceramics which are decorated with metal rim or glazed Heat-resistant plastic Yes Can not be used for long time microwave cooking Heat-resistant glass Yes Grill rack No Plastic film Yes It should not be used when cooking meat or chops as the over temperature may do damage to the film FOR THE FIRST USE As there is manufacturing residue or oil remained on the oven cavity or heat element, it usually would smell the odor, even a slight smoke, It is normal case and would not occur after several times use, keep the door or window open to ensure good ventilation. So it is strongly recommended to place a cup of water in the turntable, setting at high power and operate for several times. 2 IMPORTANT SAFEGUARDS The following basic precautions should always be followed when using electrical appliance: 1. Read all instructions before using. 2. Make sure the voltage in your living area corresponding to the one shown on the rating label of the appliance. And the wall socket is properly grounded. 3. To reduce the risk of fire in the oven cavity: a. Do not overcook the food. b. Remove wire twist-ties from paper or plastic bags before placing bags in the oven. c. Do not heat oil or fat for deep drying as the temperature of oil cannot be controlled. d. After use wipe the waveguide cover with a damp cloth, followed by dry cloth to remove any food splashes and grease. Built-up grease may overheat and begin to cause smoke or catch fire. e. If materials inside the oven should smoke or ignite, keep oven door closed, turn oven off and disconnect the power supply. f. Close supervision is necessary when using disposable containers made from plastic, paper or other combustible material. 4. To reduce the risk of explosion and sudden boiling: a. Do not place sealed containers in the oven. Baby bottles fitted with a screw cap or teat are considered to be sealed containers. b. When boiling liquid in the oven, use the wide-mouthed container and stand about 20 seconds at the end of cooking to avoid delayed eruptive boiling of liquids. c. Eggs in their shell, whole hard-boiled eggs, potatoes, sausage and chestnut should be peeled or pierced before cooking. d. The cooked eggs or liquid should not be removed out immediately. Several moments should be waited before removing In order to avoid possible hazards caused by delayed eruptive boiling of liquids. e. The contents of feeding bottles and baby food jars are to be stirred or shaken and the temperature is to be checked before consumption, in order to avoid burns. 5. Never operate the oven further if the door is damaged or the oven is malfunctioned or supply cord is damaged. Return the appliance to the nearest authorised service center for repair and maintenance. Never try to adjust or repair the oven yourself. 6. If the supply cord is damaged it must be replaced by the manufacturer or its service agent or a qualified technician in order to avoid a shock hazard. 7. After cooking, the container is very hot. Using gloves to take out the food and avoid steam burns by directing steam away from the face and hands. 8. Slowly lift the furthest edge of dishes cover and microwave plastic wrap and carefully open popcorn and oven cooking bags away from the face. 9. To prevent the turntable from breaking: a. Let the turntable cool down before cleaning. b. Do not place hot foods or utensils on the cold turntable. c. Do not place frozen foods or utensils on the hot turntable. 10. Make sure the utensils do not touch the interior walls during cook…
