WARNING: THIS APPLIANCE MUST BE EARTHED To wire an appropriate plug, follow the wiring code given in ‘To replace the mains plug’ on page GB-33.

HOW YOUR OVEN WORKS

Microwaves are energy waves, similar to those used for TV and radio signals.
Electrical energy is converted into micro-wave energy, which is directed into the middle bottom of the cavity via a wave-guide. Then the microwave stirrer distribute the microwave energy to every corner of the cavity evenly.
Microwaves cannot pass through metal, because of this the oven cavity is made of metal and there is a fine metal mesh on the door.
During cooking the microwaves bounce off the sides of the oven cavity at random.

Microwaves will pass through certain materials, such as glass and plastic, to heat the food. (See ‘Suitable Ovenware’ on page GB-28).
Water, sugar and fat in food absorb micro-waves which cause them to vibrate. This creates heat by friction, in the same way your hands get warm when you rub them together.
The outer areas of the food are heated by the microwave energy, then the heat moves to the centre by conduction, as it does in conventional cooking. It is important to turn, rearrange or stir food to ensure even heating.
Once cooking is complete, the oven automatically stops producing microwaves. Standing time is necessary after cooking, as it enables the heat to disperse equally throughout the food.

MICROWAVE POWER LEVELS

IMPORTANT: The microwave power level will default to P100 unless you press the POWER LEVEL key
Generally the following recommendations apply:

  • P100/90 – (HIGH output = 800/720W) used for fast cooking or reheating e.g. for casseroles, hot beverages, vegetables etc.
  • P80/70 – (MEDIUM HIGH output = 640/560W) used for longer cooking of dense foods such as roast joints, meat loaf and plated meals, also for sensitive dishes such as sponge cakes. At this reduced setting, the food will cook evenly without over cooking at the sides.
  • Your oven has 10 power levels, as shown.
  • To change the power level for cooking, enter the required time and then press the POWER LEVEL key until the display indicates the desired level.
  • Power level
    The microwave power level is varied by the microwave energy switching on and off. When using power levels other than P100 you will be able to hear the micro-wave energy pulsing on and off as the food cooks or defrosts.
  • Check the power level
    To check the microwave power level during cooking, press the POWER LEVEL key. As long as your finger is pressing the POWER LEVEL key the power level will be displayed. The oven continues to count down although the display will show the power level.
  • P60/50 – (MEDIUM output = 480/400W) for dense foods which require a long cooking time when cooked conventionally, eg. beef casserole, it is advisable to use this power set-ting to ensure the meat will be tender. P40/30 – (MEDIUM LOW output = 320/240W Defrost setting) to defrost, select this power setting, to ensure that the dish defrosts even-ly. This setting is also ideal for simmering rice, pasta, dumplings and cooking egg custard. P20/10 – (LOW output = 160/80W) For gent Ie defrosting, eg. cream gateaux or pastry.

MICROWAVE COOKING ADVICE

Microwaves cook food faster than conventional cooking. It is therefore essential that certain techniques are followed to ensure good results.
COOKING ADVICE NOTES:

  • When heating food in plastic or paper containers, keep an eye on the oven due to the possibility of ignition.
  • Ensure that the utensils are suitable for use in a microwave oven. (See “Suitable Cookware” on page GB-28).
  • Do not place hot foods/utensils on a cold turntable or cold foods/utensils on a hot turntable.
  • Always attend the oven when in use.
  • Liquids and foods must not be heated in sealed containers or jars/ containers with Iids on, as pressure will build up inside and may cause the contain-er/jar to explode.
  • Only use microwave popcorn within the recommended packaging (follow the manufacturers instructions). Never use oil unless specified by the manufacturer and never cook for longer than instructed.

WARNING:
Follow instructions in the SHARP operation manual at all times.
If you exceed recommended cooking times and use power levels that are too high, food may overheat, burn and in extreme circumstances, catch fire and damage the oven.

Cooking Techniques
Arrange Place the thickest parts of food towards the outside of the di sh. e.g. Chicken drumsticks.
Foods that are placed towards the outside of the dish will receive more energy, so cook quicker, than those in the centre.
Cover Certain foods benefit from being covered during microwave cooking, follow recommendations where given.
Use vented microwave ding film or a suitable Iid.
Pierce Foods with a shell, skin or membrane must be pierced in several places before cooking or reheating as steam will build up and may cause food to explode.
e.g. Potatoes, Fish, Chicken, Sausages.
NOTE: Eggs in their shells and hard/ soft boiled eggs should not be heated in the microwave oven as they may explode, even after cooking has ended.
Stir, turn and rear- range For even cooking it is essential to stir, turn and rearrange food during cooking. Always stir and rearrange from the outside towards the centre.
Stand Standing time is necessary after cooking as it enables the heat to disperse equally throughout the food.
Food Characteristics
Composition Foods high in fat or sugar (e.g. Christmas pudding, mince pies) re- quire less heating time. Care should be taken as overheating can lead to fire. Bones in food conduct heat, making the food cook more quickly. Care must be taken so that the food is cooked evenly.
Density Food density will affect the amount of cooking time needed. Light, porous foods, such as cakes or bread, cook more quickly than heavy, dense foods, such as roasts and casseroles.
Quantity The number of microwaves in your oven remains the same regard- less of how much food is being cooked. The cooking time must be increased as the amount of food placed in the oven increases. e.g. Four potatoes will take longer to cook than two.
Size Small foods and small pieces cook faster than large ones, as micro- waves can penetrate from all sides to the centre. For even cooking make all the pieces the same size.
Shape Foods which are irregular in shape, such as chicken breasts or drumsticks, take longer to cook in the thicker parts. For even cooking, place the thickest parts to the outside of the dish where they will receive more energy. Round shapes cook more evenly than square shapes when micro- wave cooking.
Temperature of food The initial temperature of food affects the amount of cooking time needed. Chilled foods will take longer to cook than food at room temperature. e.g. A cake made with chilled ingredients, (i.e. margarine) will take longer to cook than a cake made with ingredients at room temperature. The temperature of the container is not a true indication of the temperature of the food or drink. Cut into foods with fillings, for example jam doughnuts, to release heat or steam.

Face & Hands: Always use oven gloves to remove food or cookware from the oven. Stand back when opening the oven door to allow heat or steam to disperse. When removing covers (such as cling film), opening roasting bags or popcorn packaging, direct steam away from face and hands.
Check the temperature of food and drink and stir before serving. Take special care when serving to babies, children or the elderly. The contents of feeding bottles and baby food jars are to be stirred or shaken and the temperature is to be checked before consumption to avoid burns.

SUITABLE COOKWARE

To cook/defrost food in a microwave oven, the microwave energy must be able to pass through the container to penetrate the food. Therefore it is important to choose suitable cookware.
Round/oval dishes are preferable to square/ oblong ones, as the food in the corners tends to overcook. A variety of cookware can be used as listed below.

Cookware Microwave Safe Comments
Aluminium foil Foil containers ✔ / ✘ Small pieces of aluminium foil can be used to shield food from overheating. Keep foil at least 2cm from the oven walls, as arcing may occur. Foil containers are not recommended unless specified by the manufacturer, e.g. Microfoil ®, follow instructions carefully.
Browning dishes Always follow the manufacturers instructions. Do not exceed heating time given. Be very careful as these dishes become very hot.
China and ceramics ✔ / ✘ Porcelain, pottery, glazed earthenware and bone china are usually suitable, except for those with metallic decoration.
Glassware e.g. Pyrex® Care should be taken if using fine glassware as it can break or crack if heated suddenly.
Metal It is not recommended to use metal cookware as it will arc, which can lead to fire.
Plastic/Polystyrene

e.g fast food contain- ers

Care must be taken as some containers warp, melt or discolour at high temperatures.
Cling film It should not touch the food and must be pierced to let the steam escape.
Freezer/Roasting bags Must be pierced to let steam escape. Ensure bags are suitable for microwave use. Do not use plastic or metal ties, as they may melt or catch fire due to the metal ‘arcing’.
Paper – plates, cups and kitchen paper Only use for warming or to absorb moisture. Care must be taken as overheating may cause fire.
Straw and wooden containers Always attend the oven when using these materials as overheating may cause fire.
Recycled paper and newspaper May contain extracts of metal which will cause ‘arcing’ and may lead to fire.

WARNING: When heating food in plastic or paper containers, monitor the oven due to the possibility of ignition.

DEFROSTING ADVICE

Defrosting food using your microwave oven is the quickest method of all.
It is a simple process but the following instructions are essential to ensure the food is thoroughly defrosted.

Rearrange Foods that are placed towards the outside of the dish will defrost quicker than foods in the centre. It is therefore essential that the food is rear- ranged up to 4 times during defrosting. Move closely packed pieces from the outside to the centre and rear- range over-lapping areas. This will ensure that all parts of the food defrosts evenly.
Separate Foods may be stuck together when removed from the freezer. It is important to separate foods as soon as it is possible during defrosting. e.g. bacon rashers, chicken fillets.
Shield Some areas of food being defrosted may become warm. To prevent them becoming warmer and starting to cook, these areas can be shielded with small pieces of foil, which reflect microwaves. e.g. legs and wings on a chicken.
Stand Standing time is necessary to ensure food is thoroughly defrosted. Defrosting is not complete once the food is removed from the micro- wave oven. Food must stand, covered, for a length of time to ensure the centre has completely defrosted.
Turn over It is essential that all foods are turned over at least 3 – 4 times during defrosting. This is important to ensure thorough defrosting.

NOTES:

  • Remove all packaging and wrapping before defrosting.
  •  To defrost food, use microwave power levels MEDIUM LOW or LOW.

REHEATING ADVICE

For the reheating of foods, follow the advice and guidelines below to ensure food is thoroughly reheated before serving.

Plated meals Remove any poultry or meat portions, reheat these sep arately, see below.
Place smaller items of food to the centre of the plate, larger and thicker foods to the edge. Cover with vented micro- wave cling film and reheat on MEDIUM, stir/ rearrange half- way through reheating.
NOTE: Ensure the food is thoroughly reheated before serving.
Sliced meat Cover with vented microwave ding film and reheat on ME- DIUM. Rearrange at least once to ensure even reheating. NOTE: Ensure the meat is thoroughly reheated before serving.
Poultry por tions Place thidest parts of the portions to the outside of the dish, cover with vented microwave cling film and reheat on MEDIUM HIGH. Turn over halfway through reheating.
NOTE: Ensure the poultry is thoroughly reheated before serving.
Casseroles Cover with vented microwave cling film or a suitable Iid and reheat on MEDIUM.
Stir frequently to ensure even reheating.
NOTE: Ensure the food is thoroughly reheated before serving.

To achieve the best results when reheating, select a suitable microwave power level appropriate to the type of food. e.g.nA bowl of vegetables can be reheated using HIGH, while a lasagna which contains ingredients that cannot be stirred, should be reheated using MEDI UM.
NOTES:

  • Remove food from foil or metal containers before reheating.
  •  Reheating times will be affected by the shape, depth, quantity and temperature of food together with the size, shape and material of the container.

Never heat Liquids in narrow-necked containers, as this could result in the contents erupting from the container and may cause burns.

  •  To avoid overheating and fire, special care must be taken when reheating foods with a high sugar or fat content, e.g. minee pies or Christmas pudding.
  • Never heat oil or fat for deep frying as this may lead to overheating and fire.
  •  Canned potatoes should not be heated in the microwave oven, follow the manufacturer’s instructions on the can.

The contents of feeding bottles and baby food jars are to be stirred or shaken and the temperature is to be checked before consumption to avoid burns.

CLEANING & MAINTENANCE

OVEN INTERIOR
  • It is important to clean the interior of your microwave oven after each use.
  • To clean the oven interior, use a mild detergent solution, such as washing-up liquid, with warm water on a soft cloth.
  • Food and liquid splashes will build-up on the oven walls and ceiling. If grease, fat and food debris is allowed to build-up in the oven interior it may overheat, smoke or even catch fire when next using the oven.
  • Keep the waveguide cover clean at all times. The waveguide cover is constructed from a fragile material and should be cleaned with care (follow the cleaning instructions above). NOTE: Excessive soaking may cause disintegration of the waveguide cover.
    The waveguide cover is a consumable part and without regular cleaning, will need to be replaced.
  • Food will release steam during cooking and cause condensation inside the oven and door. It is important to wipe the oven dry. A buildup of condensation will eventually lead to rust forming on the oven interior.
  • Do not allow grease or dirt to build- up on the door seals or areas around the door. This may prevent the door from closing correctly and may cause a leakage of micro-waves (follow the cleaning instructions opposite).
  • Ensure the turntable and roller stay are cleaned after every use with a mild washing-up liquid solution and dried. This will prevent the build- up of grease and food debris.
    The turntable is dishwasher safe.
  • CLEAN THE OVEN AT REGULAR INTERVALSAND REMOVE ANY FOOD DEPOSITS. Failure to maintain the oven in a clean condition could lead to a deterioration of the surface that could adversely affect the life of the appliance and possibly result in a hazardous situation.
OUTER CABINET
  • Wipe the outside of the microwave oven with a mild detergent solution, such as washing-up liquid, with warm water on a soft cloth.
  • The control panel must be wiped clean and dried with the door open, therefore inactivating the oven.

NOTES:

  • Never use spray cleaners, oven pads or abrasive scourers as these damage the surface of the oven.
  • A steam cleaner should not be used.
  • Take care not to let soapy water drip through the small holes in the oven walls and the cavity floor. Excess water spillage through these holes will cause damage to the oven interior.

TROUBLESHOOTING

If you think the oven is not working properly there are some simple checks you can carry out yourself before calling an engineer. This will help prevent unnecessary service calls if the fault is something simple. Follow this simple check below:
Place half a cup of water on the turntable and close the door. Select HIGH and programme the oven to cook for 1 minute.

  1. Does the oven lamp come on when it is cooking?
  2. Does the turntable rotate?
  3. Does the cooling fan work? (Check by placing your hand above the air vent openings.)
  4. After I minute does the audible signal sound?
  5. Is the water in the cup hot?
    If you answer “NO” to any question first check that the oven is plugged in properly and the fuse has not blown. If there is no fault with either; check against the chart below.

NOTE:
If you cook food for more than the standard time (see chart below) using the same cooking mode, the oven’s safety mechanisms automatically activate.The microwave power level will be reduced.

Cooking Mode Standard Time
Microwave HIGH cooking 20 Minutes

WARNING:
Never adjust, repair or modify the oven yourself. It is hazardous for anyone other than a SHARP trained engineer to carry out servicing or repairs.
This is important as it may involve the removal of covers that provide protection against microwave energy.

  • The door seal stops microwave leakage during oven operation, but does not form an airtight seal. It is normal to see drops of water, light or feel warm air around the oven door. Food with a high moisture content will release steam and cause condensation inside the door which may drip from the oven.
  • Repairs and Modifications: Do not attempt to operate the oven if it is not working properly.
  • Outer Cabinet & Lamp Access: Never remove the outer cabinet. This is very dangerous due to high voltage parts inside which must never be touched, as this could be fatal.
    Your oven is not fitted with a lamp access cover. If the lamp fails, do not attempt to replace the lamp yourself, call a SHARP approved service facility.
QUERY ANSWER
Draught circulates around the door. When the oven is working, air circulates within the cavity.
The door does not form an airtight seal so air may escape from the door.
Condensation forms in the oven, and may drip from the door. The oven cavity will normally be colder than the food being cooked, and so steam produced when cooking will condense on the colder surface.

The amount of steam produced depends on the water content of the food being cooked. Some foods, such as potatoes have a high moisture content. Condensation trapped in the door glass should clear after a few hours.

Flashing or arcing from within the cavity when cooking. Arcing will occur when a metallic object comes into close proximity to the oven cavity during cooking. This may possibly roughen the surface of the cavity, but would not otherwise damage the oven.
Arcing potatoes. Ensure all “eyes” are removed and the potatoes have been pierced, place directly onto the turntable or in a heat resistant flan dish or similar.
The display is lit but the control panel will not work when pressed. Check the door is closed properly.
Oven cooks too slowly. Ensure correct power level has been selected.
Oven makes a noise. The microwave energy pulses ON and OFF during cooking/defrosting.
Outer cabinet is hot. The cabinet may become warm to the touch – keep children away.
