blocked during operation the
oven may overheat. In this case
the oven is protected by a
thermal safety device and
resumes operation only after
cooling down.

replace the oven light, please
consult your dealer.
Accessories
The oven comes equipped with a
variety of accessories. Always
follow the directions given for use
of the accessories.

Q If the food or cooking vessel on
the glass tray touches the oven
walls and stops the tray rotating,
the tray will automatically rotate
in the opposite direction. This is
normal. Open oven door,
reposition the food and restart.
Q Do not cook foods directly on the
glass tray. Always place food in a
microwave safe dish.

and possibly damage the interior
of the oven.
Short cooking time
As microwave cooking time is
much shorter than other cooking
methods, it is essential that
recommended cooking time is not

food.
Factors that may affect cooking
time are: preferred degree of
cooking, starting temperature,
altitude, volume, size and shape of
foods and utensils used. As you
become familiar with the oven, you
will be able to adjust these factors.
It is better to undercook rather than
overcook foods. If food is
undercooked, it can always be
returned to the oven for further
cooking. If food is overcooked,
nothing can be done. Always start
with minimum cooking time.
Small quantities of food
Take care when heating small
quantities of food as these can

cooked too long. Always set short
cooking time and check the food
frequently.
Foods low in moisture
Take care when heating foods low
in moisture, e.g. bread items,
chocolate, popcorn, biscuits and
pastries. These can easily burn,

too long. We do not recommend
heating foods low in moisture such
as popcorn or bread.
This oven has been developed for
food use only.
We do not recommend to use for
heating non food items such as
wheat bags or hot water bottles.
Reheating
It is essential that reheated food is
served “piping hot”.
Remove the food from the oven
and check that it is “piping hot”, i.e.
steam is being emitted from all
parts and all sauce is bubbling.
(You may choose to check the food
has reached 72 °C with a food
thermometer – but remember do
not use this thermometer inside the
microwave.)
For foods that cannot be stirred,
e.g. lasagne, shepherds pie, the
centre should be cut with a knife to
test it is well heated through. Even if
a manufacturer’s packet instructions
have been followed always check
the food is piping hot before serving
and if in doubt return your food to
the oven for further heating.
Standing time
Standing time refers to the period
at the end of cooking or reheating
when food is left before being
eaten, i.e. it is a rest time which
allows the heat in the food to
continue to conduct to the centre,
thus eliminating cold spots.

Important safety instructions
Lids
Always remove the lids of jars and
containers and takeaway food
containers before you microwave
the food. If the lid remains, then
steam and pressure might build up
inside and cause an explosion
even after the microwave cooking
has stopped.
Babies bottles and food jars
When reheating babies bottles
always remove top and teat. Liquid
at the top of the bottle will be much
hotter than that at the bottom and
must be shaken thoroughly before
checking the temperature. This
should be carried out before
consumption to avoid burns. See
page 26.
Boiled eggs
Eggs in their shell and whole
hard-boiled eggs should not be
heated in microwave ovens since
they may explode even after
microwave heating has ended.
Foods with skins
Potatoes, apples, egg yolk, whole
vegetables and sausages are
examples of food with non porous
skins. These must be pierced using
a fork before cooking to prevent
bursting.
Paper and plastic
When heating food in plastic or paper
containers, keep an eye on the oven
due to the possibility of ignition. Do
not use wire twist-ties with roasting
bags as arcing will occur.
Do not use re-cycled paper products,
e.g. Kitchen roll unless they say they

Liquids
Microwave heating of beverages
can result in delayed eruptive
boiling, therefore care should be
taken when handling the container.
To prevent the possibility of sudden
boil the following steps should be
taken:
a) Avoid using straight-sided
containers with narrow necks.
b) Do not overheat.
c) Stir the liquid before placing the
container in the oven and again
halfway through the heating
time.
d) After heating, allow to stand in
the oven for a short time, stirring
again before carefully removing
the container.
Deep fat frying
Do not attempt to deep fat fry in
your oven.
Arcing
Arcing may occur accidentally if a
metal container has been used or
the incorrect weight of food is used.

in the microwave oven. If this
occurs, stop the machine
immediately. If the oven is left
unattended and this continues it
can damage the machine.
Meat thermometer
Use a meat thermometer to check the
degree of cooking of joints and poultry
only when meat has been removed
from the microwave. If undercooked,
return to the oven and cook for a few
more minutes at the recommended
power level. Do not leave a
conventional meat thermometer in the
oven when microwaving.

General guidelines
STANDING TIME
Dense foods e.g. meat, jacket potatoes
and cakes, require standing time
(inside or outside of the oven) after

conducting to the centre of the food to
cook through 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

2–5 minutes standing. If food is not
cooked after standing time, return to
the oven and cook for additional time.
After defrosting food, standing time
should also be allowed.
QUANTITY
Small quantities cook faster than large
quantities, and small meals will reheat
more quickly than large portions.
SPACING
Foods cook more quickly and evenly if
spaced apart. NEVER pile foods on top
of each other.
MOISTURE CONTENT
Many fresh foods e.g. vegetables and
fruit, vary in their moisture content
throughout the season. For this reason
cooking time may have to be adjusted.
Dry ingredients e.g. rice, pasta, can dry
out during storage so cooking time may
differ.
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.

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.
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. Food temperature should
be between 5 and 8 °C before cooking.
LIQUIDS
All liquids must be STIRRED BEFORE,
DURING AND AFTER heating. Water
must be stirred before and during
heating, to avoid eruption.
Do not heat liquids that have previously
been boiled. DO NOT OVERHEAT.
TURNING AND STIRRING
Some foods require stirring during
cooking. Meat and poultry should be
turned after half of 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.
CHECKING FOOD
It is essential that food is checked
during and after a recommended
cooking time, even if an AUTO
PROGRAMME has been used (just as
you would check food cooked in a
conventional oven). Return the food to
the oven for further cooking if
necessary.
DISH SIZE
Follow the dish sizes given in the
recipes, as these affect the cooking
and reheating times.
A quantity of food spread in a bigger
dish cooks and reheats faster.
CLEANING
As microwaves work on food particles,
keep your oven clean at all times.
Stubborn spots of food can be removed
by using a microwave spray cleaner,
sprayed onto a soft cloth. Always wipe
the oven dry after cleaning.
