Appliance safety considerations
Important Information
❑If using hot air v, do not place
greaseproof paper loosely in the oven
(e.g. when heating the oven).
The hot-air fan could draw in the paper
which may damage the heater and fan.
❑Do not clean the oven with steam or
high-pressure cleaners.
❑Do not insert a baking sheet at the
bottom of the oven, or cover the base of
the oven with aluminium foil, as this
would result in heat build up. Roasting
and baking times would change, and
the enamel would be damaged.
❑Never pour water directly into the hot
oven. Damage to the enamel could
result.
❑Dripping juices may leave spots on the
oven lining. Always place a baking tray
below to prevent this from happening.
❑Never stand or sit on the open oven
door.
❑The oven door must close properly.
Keep the door seal surfaces clean.
❑The appliance should only be used for
the preparation of food.
❑The surfaces of heating and cooking
appliances get hot during operation.
The interior oven walls and the heating
elements get extremely hot. Always
keep children away from the appliance.
❑Never leave the appliance unattended
when cooking with fat or oil. They can
catch fire if overheated.
❑Clean the oven regularly.
Fatty or oily remants could ignite when
the oven is switched on.
❑Make sure that the power cord does not
get caught in the hot oven door. The
plastic insulation could melt.
❑In the case of a defect, switch off (or
remove) the mains fuse in the building
electrical system.
❑Do not store combustible items in the
oven. They could ignite if the oven is
switched on accidentally.
Open the oven door
carefully.
Hot steam may escape.

Baking
Using baking tins
❑Always place baking tins in the centre
of the wire shelf.
Circotherm: v
❑You can use baking tins of any material
and of any colour, as long as they are
oven-proof.
❑Do not place baking tins or high cakes
too close to the rear oven wall.
Conventional heat: e
❑Dark-coloured baking tins made of metal
give the best results.
❑The wire shelf may be turned upside
down to accommodate different size
tins.
❑If the cake base gets too dark:
Check the shelf level. Shorten the
baking time, and possibly use a lower
baking temperature.
❑If the cake base stays too light:
Check the shelf level. Increase the
baking time, select a lower temperature,
or use a dark metal baking tin.
Notes:
❑You can influence the degree of
browning by changing the temperature
setting.
❑If a cake collapses after removing it from
the oven, use less liquid on your next
attempt, consider using a longer baking
time, or use a slightly lower temperature
setting.

17
Roasting
Roasting with Circotherm v
Notes:
❑Meat roasted using the Circotherm
system will brown on all sides and stay
moist without additional fat.
❑Choose cuts of meat that weigh
150 grams (5 oz) or more.
❑Place the shelf on top of the roasting
pan.
❑Place the meat on the shelf, season if
desired.
❑Slide the pan and shelf into the oven on
the same shelf position.
❑No pre-heating is required. Save energy
by putting the roast into the cold oven.
❑Use a Circotherm temperature of 160 °C.
❑Let the meat rest for 10 minutes after
roasting, this will allow the juices to
settle and prevent them from running
out of the meat when carved.
Roasting with
Conventional heat e
❑Follow the steps above. With fatty meat
125–250 ml (4–8 floz) of water can be
poured into the roasting pan.
❑Baste the meat if desired.
❑Place in a cold oven to save energy or
pre-heat if desired.
Casseroling or pot-roasting in a covered
dish:
❑Some meats should be prepared in
liquid in a covered casserole. This type
of cooking is suitable for less tender
cuts of meat.
❑Place the casserole on the wire shelf on
a suitable shelf position.
Cooking tips:
❑Only use ovenproof cookware.
❑Extra large turkeys and joints can be
placed directly in the roasting pan and
not on the wire shelf.
❑Cover large turkeys with foil during
cooking. Remove foil during the last
hour.
Circo-roasting I
Use this method for particularly crispy
poultry or pork with crackling.
❑Use the shelf and roasting pan together.
Turn large roasts after about half of the
total cooking time has elapsed. Use
shelf 1 or 2 for circo-roasting.
❑Some types of food (e.g. fatty meats)
will spit during Circo-roasting.
Therefore, to prevent burning-on of the
stains, thorough cleaning of the oven is
recommended after use.
❑Whole poultry should be turned after
approx. two-thirds of the cooking time
has elapsed. With duck and goose,
pierce the skin under the wings to allow
excess fat to drain off.
❑After the end of the selected roasting
time and with the oven switched OFF,
leave the roast in the closed oven for
approx. 10 minutes.

18
Grilling
Radiant grilling Zand 0
Used for small cuts of meat or poultry.
Z=centre-area grill for small amounts
of food
0=full-surface grill for larger amounts
of food
❑Always use the shelf and roasting pan
together.
❑Turn the food after approx. two-thirds of
the grilling time has elapsed.
❑Always place the food to be grilled in the
centre of the wire shelf.
❑If the heating element switches off
automatically, the overheating protection
was activated. The element will be
reactivated after a short period of time.
Exercise CAUTION when grilling.
!Always keep children away from the
oven when it is in use.
Notes on grilling:
❑Always close the oven door when
grilling.
❑The grilling temperatures are variable.
❑Always use the shelf and the roasting
pan.
❑Lightly brush the wire shelf with oil and
baste the food if desired.
Circotherm grilling v
Use this method for small cuts of meat –
steaks, chops, sausages, bacon, chicken
joints and fish.
❑Use the shelf and roasting pan together.
❑Season meat as required.
❑Place on shelf.
❑Do not turn food over – the hot air will
circulate around the food cooking all
sides.
❑Use a temperature of 180–190 °C.

19
Cooking Tips and Helpful Hints
To save energy:
❑Preheat only if recommended by the
recipe.
❑Dark baking tins have a higher degree of
heat absorption.
❑Residual heat: In the case of longer
baking times, you can switch off the
oven 5–10 minutes before the full baking
time has elapsed.
When cooking with Circotherm:
❑Cakes baked in a tin get too dark at the
back.
❑Cakes remain doughy and collapse
when removed from the oven.
❑Uneven browning of small cakes or
biscuits.
❑With very moist foods steam develops
and condenses on the oven door and
drips onto the floor.
When cooking conventionally:
❑The bottom of a cake baked on a
baking tray stays too light.
❑The cake gets too dry.
❑The inside of the cake remains spongy
or doughy, or meat stays raw in the
centre.
Avoid blocking the air vents at the rear wall
of the oven with the cake tins.
Reduce the temperature for deep cakes.
Bake for a longer period of time. Test with
a skewer before removing.
Avoid placing trays too close to the back
wall. Space food on the tray.
Several brief periods of opening the oven
door during baking (1 or 2 times, more
frequently with longer roasting times) will
aid in venting the steam in the oven and
reduce condensation.
Ensure that no other pans or trays are in
the oven. Lower shelf position.
Place tin on wire shelf.
Select a slightly higher oven temperature.
Cook for shorter period of time.
Use a slightly lower temperature and cook
for a longer time. Reduce the liquid in the
cake mixture.

20
Defrosting and Cooking
Defrosting and cooking using the Circotherm v
Important heating system information:
❑For defrosting and cooking of frozen
foods, use circotherm.
❑With all frozen foods, follow the food
manufacturers instructions on the
package.
❑As a rule, defrosted frozen foods
(especially meats) require less cooking
time than fresh products, since freezing
has a pre-cooking effect.
❑If frozen meat is placed in the oven, the
defrosting time must be added to the
required cooking time.
❑Always defrost frozen poultry before
cooking because the giblets must be
removed.
❑For cooking frozen fish, use the same
temperatures as for fresh fish.
❑Frozen ready-to-eat meals in
aluminium dishes may be placed into
the oven several at a time.
❑Frozen vegetables (i.e., when cooking
complete meals) should be cooked in a
covered pot together with the roast. Use
only approximately half of the liquid
specified in the recipe. Use fat only for
adding flavour.
Standard defrosting of various foods:
Shelf-in levels:
With 1 baking sheet: Slide-in level 3
With 2 baking sheets: Slide-in levels 1and 3
❑All stated times are approximate
guidelines that vary with the shape and
volume of frozen products.
❑Raw frozen products or foods from a
freezer always defrost at 50° C.
Higher defrosting temperatures may
cause the food to dry out.
❑Defrost frozen meals packed in
aluminium foil or closed aluminium
containers at a setting of 130 – 140° C.
❑Place frozen meals packed in plastic
bags or plastic containers in a pot
filled with water. Cover the pot and
defrost of 130 – 140° C.
Attention: Pot handles must be oven-
proof.
❑Defrost and warm up frozen baked
goods at 100 – 140° C. Brush bread,
rolls or yeast pastry lightly with egg to
make the crust more appealing.
❑Defrost dry frozen yeast cakes at
160 – 170° C for 20 – 30 minutes.
❑Defrost moist frozen yeast cakes (with
fruit topping) at 160 – 170° C for
30 – 50 minutes after wrapping in
aluminium foil to prevent cake from
drying out.
❑Defrost and toast frozen toast (with
topping) at 160 – 170° C for about
20 minutes.
❑Defrost and bake frozen pizzas at 180 –
190 °C for 15 – 25 minutes.
Place on wire grill covered with
greaseproof paper.
Please ensure that the greaseproof
paper is suitable for use at these
temperatures.
