Use
General notes
Always ensure that food is sufficiently cooked or reheated. Many
factors will affect the overall cooking time, including the size and amount of food, its initial temperature, changes to recipe and the shape and size of cooking container. Some foods may contain micro organisms which are only destroyed by thorough cooking, therefore when cooking or reheating foods, e.g. poultry, it is particularly important that food is fully cooked through (at over 70°C, for a minimum of 10 minutes). If in doubt select a longer cooking or reheating time.
It is important that the heat is allowed to spread evenly throughout
the food being cooked.
This can be achieved by stirring and/or turning the food, and by observing a sufficiently long standing time, which should be added to the time needed for cooking, reheating or defrosting.
7
Warning and Safety instructions
Always remember that cooking times in a microwave oven are usu-
ally considerably shorter than with traditional methods of food preparation. Excessively long cooking times can lead to food drying out and eventually burning, or could even cause it to catch fire. There is also a danger of fire if breadcrumbs, flowers, herbs, grains etc., are dried in the microwave oven. Always ensure that this type of procedure is supervised.
Exercise caution when cooking or reheating food with a high sugar
content, e.g. Christmas pudding. If heated for too long the sugar may caramelise or ignite.
Do not use full power if you warm empty dishes or dry herbs. The
lack or minimum amount of food could cause damage to the appliance.
Do not leave the oven unattended when cooking with oils and fats as these can be a fire hazard if allowed to
overheat.
If smoke occurs in the oven, to avoid fuelling any flame do not
open the oven door. Turn the function selector to "0", or switch off at the mains and remove the plug from the socket. Do not open the oven door until the smoke has dispersed.
Never heat undiluted alcohol in the microwave oven as this can easily
ignite.
Do not heat up unopened tins of food in the oven as pressure will build up in the tin and it can explode. This could result in injury or damage.
Food left in the oven to take advantage of residual heat should always
be covered to avoid it drying out, and to avoid a possible build-up of condensation which could adversely affect the oven interior.
Try to avoid the interior walls being splashed with food or liquids con-
taining salt. If it does happen wipe these away thoroughly, to avoid corrosion on the stainless steel surface.
Wear oven gloves when removing the glass tray from the oven. If the glass tray has a heavy load, pull it only
slightly towards you, and then hold firmly at the sides as you take it out.
The glass dish and the rack take a maximum load of 8 kg. Do not ex-
ceed this or the accessories may be damaged.
Do not lean or sit on the open oven door. This could damage the appli-
ance. Take care in the region of the hinges. An oven door can support a maximum load of 8 kg.
When it is hot do not place the glass tray on a cold surface, such
as a tile or granite worktop . It could break. Place it on a pot rest or a wire rack.
Under no circumstances use a steam cleaner to clean this appli-
ance. The steam could attack the electrical components and cause a short circuit, or permanent damage to the surface and to components, for which the manufacturer of the oven cannot accept any responsibility.
8
Warning and Safety instructions
Do not use the oven to heat up the room. Due to the high temperatures
radiated, objects left near the oven could catch fire.
When using kitchen appliances connected to sockets near the
oven ensure that the cable cannot get trapped in a hot oven door, which could melt the cable insulation and be dangerous.
In countries which may be subject to infestation by cockroaches or
other vermin, pay particular attention to keeping the appliance and its surroundings in a clean condition at all times.
Any damage which might be caused by cockroaches or other vermin will not be covered by the appliance guarantee.
Microwave function
Before serving remember to allow sufficient standing time and then
always check the temperature of the actual food itself after taking it out of the oven. Do not be misled by the temperature of the container which does not necessarily give a correct indication of the temperature of the food or liquid in it. This is particularly important when preparing food for babies, children, and the elderly or infirm.
Never cook or reheat food or liquids in sealed containers or bottles. With baby bottles the screw top and teat must be removed. Otherwise
pressure builds up which can cause the bottle or container to explode posing a severe risk of injury.
When heating liquids, the boiling rod provided should be placed into
the container.
When heating liquids, milk, sauces etc., in the oven without the boiling rod, the boiling point of the liquid may be reached without the production of typical bubbles. The liquid does not boil evenly throughout. This so-called 'boiling delay' can cause a sudden build up of bubbles, when the container is removed from the oven or shaken. This can lead to the liquid boiling over suddenly and explosively. There is a danger of burning. The formation of bubbles can be so strong that the pressure forces the oven door open. The user could be injured and the appliance damaged.
The boiling rod ensures that the liquid boils evenly and that bubbles form at an early stage during the operation.
9
Warning and Safety instructions
Do not use any containers or cutlery made from or containing metal,
aluminium foil, lead crystal glassware, temperature-sensitive plastics, wooden utensils or cutlery, metal clips or wire ties. Such items could be damaged, or cause a fire hazard.
The rack supplied with the appliance is designed to be compatible with microwaves, and can therefore be used with or without the microwave function.
The rack gets hot when operating either the micwowave function or the browning element, or both. There is
a danger of burning.
Eggs can only be cooked in their shells in the microwave oven in a specially designed egg-boiling device
available from specialist shops. Similarly, hard-boiled eggs should not be reheated in the microwave oven as this may lead to the eggs bursting, even once they have been removed from the oven.
Eggs can be cooked without their shells in the microwave oven only if
the yolk membrane has been punctured several times first. The pressure could otherwise cause the egg yolk to explode.
Do not reheat food in the oven in heat-retaining bags intended for
normal ovens. These heat-retaining bags usually contain a thin layer of aluminium foil which reflects microwaves. This reflected energy can, in turn, cause the outer paper covering to become so hot that it ignites.
Food with a thick skin or peel, such as tomatoes, sausages, jacket po-
tatoes, aubergines, should be pierced or cut in several places to allow steam to escape and prevent the food from bursting.
Ovenproof earthenware can retain a considerable amount of moisture.
Earthenware and porcelain containers with hollow handles and lid knobs must only be used in this oven if they have vent holes, which allow the moisture to escape. Without vent holes there can be a pressure build-up, causing the container to crack or shatter, with the danger of injury.
Traditional oven functions:
Fan Heat, Grill
Caution - Danger of burning When the oven is being used as a traditional oven it can get very hot.
Great care should be taken to ensure that small children do not
touch the oven when it is being used. External parts of the oven such as door glass, handle vents and the facia panel can become quite hot.
Wearing heat-resistant oven gloves is recommended when placing
food in the oven, turning it or removing it. When the Grill function has been chosen, either solo or in a combination programme the element becomes very hot and there is a danger of burning.
10
Warning and Safety instructions
Wait until the element has cooled down before lowering it for clean-
ing.
Do not use force to pull it down as this can cause the element to
break.
Bottling
Bottling should only be undertaken by an experienced cook who has received proper training in this method of preserving fruit and vegetables in an oven or microwave oven, and understands the implications of the chemical reactions involved.
The manufacturer cannot be held liable for damage caused by non-com- pliance with these Warning and safety instructions.
11
Caring for the environment
Disposal of the packing material
The transport and protective packing has been selected from materials which are environmentally friendly for disposal and can normally be recycled.
Ensure that any plastic wrappings, bags etc. are disposed of safely and kept out of the reach of babies and young children. Danger of suffocation!
Rather than just throwing these materials away, please ensure they are offered for recycling.
Disposal of your old appliance
Old appliances may contain materials which can be reclaimed or recycled. Please contact your dealer, your local waste collection centre or scrap merchant about potential recycling schemes.
Before discarding an old appliance switch off and disconnect it from
the power supply. This should be done by a competent person. Cut off and render any plug useless.
Cut off the cable directly behind the appliance to prevent misuse.
Ensure that the appliance presents no danger to children while being stored for disposal.
12
Operating modes
Microwave h
Microwave cooking offers the benefits of speed, convenience and nutritional advantages when food does not require browning or crisping.
Functional description
This oven is equipped with a magnetron a, which converts electrical energy into microwaves.
A stirrer fan b above the oven ceiling distributes the microwaves evenly throughout the oven interior, rebounding them off the walls so that they reach and enter the food from all sides.
In order for microwaves to reach the food, they must be able to penetrate the cooking utensil being used.
Microwaves can penetrate porcelain, glass, cardboard and plastics but not metal. Do not, therefore, use utensils made of metal, or which contain metal, for example in the form of gold or silver trim. The metal reflects the microwaves and this could lead to the creation of sparks. The microwaves cannot be absorbed.
All food contains moisture molecules which, when subjected to microwave energy, start to oscillate 2.5 thousand million times a second. The friction caused by this vibration creates heat, which first starts developing around the outside of the food and then slowly penetrates towards the centre. The moisture, fat and sugar content of food will affect the speed at which it is cooked.
As heat is produced directly in the food,
–food can generally be cooked without adding much liquid or cooking oil
–cooking, reheating and defrosting in a microwave oven is quicker than using traditional oven methods
–nutrients, such as vitamins and minerals, are generally retained
–colour, texture and taste of food are not impaired
–the surface temperature stays cool enough to avoid browning.
13
Operating modes
Traditional oven functions
Fan Heat D
Grill n
These cook and brown the food.
Fan Heat D
The fan circulates heat constantly around the oven, giving a very even temperature throughout.
It sucks in the air, heats it over a ring element and blows it back through the carefully spaced openings in the back panel.
As the heat is quickly transferred to the food, it is not usually necessary to preheat the oven, except when roasting sirloin or fillet or for foods such as puff pastry and yeast mixtures which require instant heat.
With Fan Heat food can be baked or roasted on both levels at the same time.
Grill n
Note that this function is best suited to browning food and for grilling very thin cuts of food.
As the element needs to radiate a high heat in order to cook the food, it will take several minutes after being switched on to glow red hot and so produce sufficient infra-red heat for grilling. Pre-heat the with the oven door closed for approx. 5 minutes before starting to cook.
Combination programmes
Microwave + Fan Heat h + D
Microwave + Grill h + n
The combination programmes enable the grill or the fan setting to be used in conjunction with the microwave facility.
A microwave power level and cooking time are programmed together with either the grill or the fan to run simultaneously.
This enables cooking times to be reduced, yet a crisp, brown result can still be achieved without compromising the flavour or texture of the recipe.
In general when using combination programmes, you should not set the microwave power level higher than 150 W for baking, and not higher than 450 W for cooking and grilling.
14
Time of day
After the appliance has been con-
nected to the power supply or after a power cut 0•00 with AUTO on the left will
flash in the display.
The time of day must be set before any other processes can be set.
Setting time of day (24 hour clock)
Midnight (24 hours) is shown as 0•00.
^Press the g and h buttons at the same time.
The dot after the first figure in the display starts flashing. Whilst it is flashing, (approx. 4 seconds) set the time of day. It is shown in hours•minutes.
^Use the + or – button to enter the time of day.
After four seconds if no further entry is made, the oven display shows this time. The dot between the figures now stays on constantly to indicate that the time of day has been set.
15
Before using for the first time
^Wipe out the oven interior with hot water and a little washing up liquid. Dry using a soft cloth.
Do not shut the oven door until the interior is completely dry, to avoid odours and the possibility of corrosion developing.
^ Wash the accessories.
With new appliances there is usually a smell during the first use. It is dispelled more quickly by using a high temperature as follows:
Run the oven on the Fan Heat D setting for at least an hour:
^Select Fan Heat D with the function selector.
The cooling fan starts up and the oven interior light comes on.
^Turn the temperature selector to 200 °C.
Only turn the temperature selector clockwise and then back again anticlockwise. Do not force it past the resistance. Otherwise it could be damaged.
The oven begins to heat up. The indicator light on the control panel stays alight while the oven is heating up.
Ensure the room is well ventilated during this process.
16
Suitable containers for microwave ovens
Microwaves |
Material and shape |
– are reflected by metal,
–pass through glass, chinaware, plastic and card,
– and are absorbed by food.
The material and shape of containers used affect cooking results and times. Heat distribution is more even in round and oval shaped dishes than in rectangular containers, providing better results.
Metal
Metal containers, aluminium foil and metal cutlery, or china with metallic decoration such as gold rims or cobalt blue must not be used in microwave mode.
The metal reflects the microwaves, hindering the cooking process.
Exceptions:
If recommended by the producer, precooked meals packed in aluminium foil containers can be defrosted and reheated in the microwave oven. Important: remove the lid first. However, as food is only heated from the top, it is better to remove the food from the aluminium foil container and transfer it to a dish suitable for a microwave oven. The heat distribution will be more even. If sparks and arcing occur when using a metal container, stop and transfer the food to a microwave safe container.
For even defrosting and to avoid overcooking unevenly shaped cuts of meat, poultry or fish, small pieces of aluminium foil may be used to mask wingtips or other thin parts for the last few minutes of the process.
17
Suitable containers for microwave ovens
Make sure that the aluminium foil is at least 2 cm from the oven walls at all times. It must not touch the walls.
Metal meat skewers or clamps should only be used if they are very small in comparison to the size of the cut of meat.
The rack supplied with the appliance is suitable for use in a microwave oven. Do not place the rack on the oven floor.
The rack can get hot.
Glassware
Heat-resistant glass or ceramic glass are ideal for use in the microwave oven.
Crystal glass contains lead which could cause the glass to crack. Glass dishes with a milled rim are subject to the same risk. Both are unsuitable.
Earthenware
Although some ovenproof earthenware can be used in a microwave oven it may contain a considerable amount of moisture, causing it to become hot during use. It is normally advisable to avoid using it in a microwave oven.
Earthenware containers with hollow handles and lid knobs must only be used if they have vent holes, which allow the moisture to escape. Without vent holes there can be a pressure build-up, causing the container to crack or shatter, with the danger of injury.
Decorated earthenware is only suitable if the decoration is beneath an all-over glaze.
Earthenware can get very hot, and may crack.
Porcelain (chinaware)
Porcelain is suitable, however containers with hollow handles and lid knobs must only be used if they have vent holes, which allow the moisture to escape. Without vent holes there can be a pressure build-up, causing the container to crack or shatter, with the danger of injury.
Do not use porcelain with gold or silver edging or items with hollow knobs or handles as insufficient ventilation may cause pressure.
Glazes and colours
Some glazes and colours contain metal.
This makes them unsuitable for use in a microwave oven.

Suitable containers for microwave ovens
Plastics
Plastic containers must only be used for Microwave mode alone and not in conventional oven mode.
Plastics must be heat-resistant to a minimum of 180 °C. Otherwise the plastic may melt and fuse with the food.
Special plastic utensils, designed for use in microwave ovens are available from good retail outlets. Melamine ware is not suitable as it absorbs energy and heats up. When purchasing plasticware, make sure that it is suitable for use in a microwave oven.
Disposable containers, such as trays made from polystyrene, can only be used for very short timed warming and reheating of food.
Plastic boiling bags can be used for cooking and reheating. To reduce the risk of the bag bursting, they should be pierced first so that steam can escape and prevent a build-up of pressure.
Roasting bags and -tubes
Roasting tubes should be about 40 cm longer and roasting bags about 20 cm longer than the food being roasted, and carefully tied with string. Turn the ends over and secure them. Holes should be made according to the manufacturer's instructions.Do not use metal clips or wire ties, even if bound by paper. There is a danger that they will ignite when heated.
Wood
Wooden dishes are not suitable.
Moisture contained in the wood evaporates when exposed to microwave energy, causing the wood to dry and crack.
Disposable containers
Only those plastic disposable containers which are specified by the manufacturer as suitable for use in a microwave oven may be used.
Do not leave the oven unattended when re-heating or cooking food in disposable containers made of plastic paper or other inflammable material.
Disposable containers are not always recyclable or degradable.

Testing dishes for their suitability
If in doubt as to whether glass, earthenware or porcelain plates or dishes are suitable for use in a microwave oven, a simple test can be performed:
^Place the item you wish to test in the centre of the oven, fill a suitable glass with water and also place this in the oven.
^Shut the door.
A microwave oven process cannot be started until the door is closed.
^Select Microwave h with the function selector. The cooling fan will run.
The display will show a suggested power level of 900 W.
^Press the g button.
0•00 appears in the display for approx. 4 seconds.
While it is visible enter a time of 30 seconds with the "+" control.
The c symbol appears above the dot.
^ Press the Start/Stop button.
The oven interior light comes on. The time entered counts down in the display in second steps. The c symbol stays on constantly.
If a crackling noise is heard accompanied by sparks during the test, switch off the appliance immediately. Turn the function selector to the "0" position. Any crockery which causes this reaction is unsuitable for use in the microwave oven.
At the end of this period a beep sounds three times and the c symbol flashes. Press any button to cancel them. The time of day reappears in the display and the oven interior light goes out.
The water in the glass should be warm, but the dish cool. If the dish is very hot and the water is cold, it would be unwise to use the dish.
If any doubt exists about the suitability of containers, please contact the supplier.
This test cannot be used to check whether items with hollow knobs or handles are suitable for use in a microwave oven.
