of 15 cm.
4Do not place the oven where heat, moisture or high
humidity are generated, (for example, near or above
a conventional oven) or near combustible materials
(for example, curtains). Do not block or obstruct air
vent openings, as obstructions may ignite due to the
emission of hot air.
5Makesure the powersupply cord isundamaged (See
Installation next page) and that it does not run under
the oven or oven any hot or sharp surfaces.
6The socket must be readily accessible so that it can
be easily unplugged in an emergency.

OW TO OPERATE THE OVEN
H
Introduction: Water, sugar and fat in food absorbs
microwaves and causes their molecules to vibrate. This
creates heat by friction, in the same way your hands get
warm when you rub them together.
The outer areas of food are heated by microwave
energy and the remaining portions by conduction. It is
important to turn, rearrange or stir food to ensure even
heating. Where recommended, allow food to stand, this
is not optional but is necessary to ensure thorough
cooking. It is particularly important for dense food, such
as joints of meat.
NOTES
:
•Microwaves pass through non-metallic dishes and
utensils and heat the food inside the dishes.
•Microwaves are reflected by metal.
•The oven is lined with metal and has a fine metallic
mesh in the door to prevent microwave leakage.
•Metallic dishes are not suitable for microwaving.

1.Beef Steak
2.Lamb Chops
3.Pork Chops
4.Chicken Portions
5.Fish Steaks
The oven is pre-programmed with a time and power level cycle so that the food listed above is defrosted easily.
BASIC IDEAS FOR EXPRESS DEFROST
i/ Always allow food to stand for approx. 10-30 minutes after defrosting to equalise the temperature and to produce
better defrosting results.
ii/
Check food after standing. If the item is not thoroughly defrosted, continue to defrost on 20% power for additional time.
iii/ Choose foods that are the same thickness throughout. This will produce better defrosting results. Foods which
vary in thickness may require shielding with small flat pieces of tin foil to prevent over-defrosting.
iv/ For foods not listed in the chart refer to the manual defrosting chart.
v/ When freezing chicken pieces, steak, chops and fish, freeze separately in single flat layers and if necessary
interleave with freezer plastic to seperate layers. This will ensure even defrosting.
1. Position the food with thinner parts in centre in a single layer, if
pieces are stuck together separate as soon as possible.
2. Turn over, rearrange after the audible sound.
After defrosting stand for 10-30 minutes.
1. Position the food in a single layer.
2. Shield any thinner parts with foil if necessary.

requireslessheating time andshouldbe watched, over-heating
can lead to fire. Use good quality ingredients for microwaving.
Economical cuts of meat can be used for casseroles.
Density &
quantity Food density and quantity affect the amount of cooking time
needed,for example,potatoes requiremorecooking thanpeas;
four potatoes will take longer to cook than two.
For even cooking stir, turn or rearrange food during cooking.
Where recommended, leave food to stand after cooking or
defrosting.

Initial temperature Theinitialtemperatureoffoodaffectstheamountofcookingtime
needed, for example, chilled food requires more cooking than
food 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.
Piercing Foodwithskin(e.g.potatoes,apples,fish,sausages,chicken),
or with membrane (e.g. egg whites/yolks), must be pierced in
several places before cooking or reheating. If not, steam will
build up and may cause food to explode.
Arrangement Placethickestpartsoffoodontheoutsideofthedish,e.g.place
the meaty ends of chicken drumsticks on the outside of the
dish.
Covering Fish, vegetables and certain other foods benefit from being
covered during microwave cookery, follow recommendations

Size & shape Foodsizeand shape affectthe amount ofcooking time needed.
When cooking more than one portion of the same food ensure
they are of a similar size and shape.
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.
