Reasons for
damage
Baking tray, aluminium foil Do not place the baking tray on the oven floor.
or dishes on the oven floor Do not cover it with aluminium foil.
Do not place dishes on the oven floor.
This will cause heat accumulation. The baking and
roasting times will no longer be correct and the
enamel will be damaged.
Slide-in accessories To avoid damage, insert slide-in accessories
carefully.
Baking paper If using hot air functions, 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.
Water in the oven Never pour water directly into a hot oven.
This could damage the enamel.
Fruit juice When baking very moist fruit cakes, do not put too
much on the baking sheet. Fruit juice dripping from
the baking sheet leaves stains that cannot be
removed.
It is recommended that you use the deeper universal
pan.
Cooling with the oven door Only leave the oven to cool with the door closed. Do
not allow anything to become trapped in the oven
door. Even if you only leave the oven door open
slightly, the fronts of adjacent units may become
damaged over time.
Very dirty oven seal If the oven seal is very dirty, the oven door will no
longer close properly when the oven is in use.
The fronts of adjacent units could be damaged.
Keep the oven seal clean.
Using the oven door as a Do not stand or sit on the oven door.

Additional accessories can be obtained from a specialist dealer.
Before ordering, please check the Neff sales literature to
confirm which of the following items are available in the UK: Order no.
Note:
The baking tray or universal pan may distort while the oven is operating. This is
caused by major temperature differences on the utensil. These differences may occur
if only one part of the utensil was covered or if deep-frozen food, e.g. pizza, was
placed on the utensil.
The distortion will subside again during baking, roasting or grilling.

Description of Oven Features
– main oven
Circotherm Advantages:
–low soiling of oven interior
–cooking on up to 3 shelf levels at once is possible
–shorter preheating times
–low oven temperatures
–bread baking
Circotherm grilling A system by which foods, that would normally be
grilled by direct heat from an element, are cooked
using Cirotherm. Temperatures between 180 to
190 °C are selected and the food is placed on the
wire shelf, roasting on the roasting/grill pan.
Advantages:
–ideal for steaks, sausages, chicken joints, fish,
kebabs and chops
–no turning of food is required
–three shelves of ‘grilled’ food can be prepared at
one time
–very convenient.
Defrost A fan in the rear wall of the oven circulates the air in
the oven around the frozen food.
The fan system is running without heating.
Advantages:
–Gentle defrosting.
–Frozen pieces of meat, poultry, bread and cakes
defrost evenly.
AquaCleanse The oven cleaning function featured in your oven is
(oven cleaning system) intended to help you keep your oven neat and tidy.
An amount of cleaning solution is vaporised
automatically. The combined effects of heat and
steam soften the soil deposits on the oven wall
enamel and facilitate their removal. For more
information on this function, see the section on
”Cleaning and Care” later in this booklet.
Advantages:
–takes the toil out of oven cleaning
–protects the enamel on interior surfaces
–constitutes an environmentally friendly cleaning

and bottom of the oven cavity.
Baking and roasting is possible on one shelf position
only.
Advantages:
–Baking of cake with wet fillings, pizza, quiche,
e.g.
Surface grilling The food being prepared is exposed to heat radiation
from the heating element at the top of the oven
cavity.
–Particularly effective with flat, small cuts of meat,
i.e., steaks, sausages, fish, vegetables and toast.
Large area grill Advantages:
–the entire grilling surface heats up
–especially useful with large amounts of food
Small area grill Advantages:
–only the centre area of the grilling surface heats
up
–especially useful with small amounts of food
–energy-saving operation

Switching the Oven ON and OFF
– main oven Switching the oven ON:
1. Set the temperature control knob to the desired
temperature.
The selected temperature will be controlled
automatically.
The red oven temperature control lamp illuminates
when the oven is first switched on, and extinguishes
when the required temperature has been reached.
– mini oven Before switching on your oven, you should decide
which heating system you wish to use.
Switching the oven ON:
1. Use the function selector to determine the
desired system.
2. Set the temperature control knob to the desired
temperature.
The selected temperature will be controlled
automatically.
The oven temperature control lamp illuminates when
the oven is first switched on, and extinguishes when
the required temperature has been reached.
Switching the oven OFF:
To switch the oven OFF, turn both the temperature
selector and functions selector to the »0« position.
Notes:
The appliance features a cooling fan which runs until
the oven has cooled down.

17
Baking – main oven
Using baking tins Always place baking tins in the centre of the
baking wire shelf.
We recommend dark metallic baking tins.
Notes Light coloured baking tins made from thin-wall
materials lead to longer baking times and uneven
browning of the cake.
You can influence the degree of browning by
changing the temperature setting.
If a cake collapses after removing it from the oven,
consider using a longer baking time, or use a slightly
lower temperature setting.
Using tinplate baking tins Shelf position 1
If the cake bottom gets too dark:
Check the shelf position. Shorten the baking time,
and possibly use a lower baking temperature.
If the cake bottom stays too light:
Check the shelf position. Increase the baking time,
select a lower temperature, or use a dark metal
baking tin.
Do not place baking forms or high cakes too close
to the rear oven wall.

To save energy Preheat only if expressly required by the recipe.
Dark baking tins have a higher degree of heat

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.

19
Roasting – main oven
Place the wire shelf into the universal pan
and slide them together into the same shelf
position.
Meat can be roasted in the oven in a particularly
economical fashion if the weight of the cut exceeds
750 grams.
Roasting in an uncovered Rinse the universal pan and/or the roaster
pot with water, and place the meat into it.
With fat meat and poultry, pour 125 to 250 ml of
water (to suit the size and kind of roast) into the
universal pan. At your discretion, baste lean meat
with fat, or cover it with bacon strips.
The roast drippings collecting in the universal pan
make a tasty gravy. Dissolve the drippings with hot
water, bring to a boil, thicken with corn starch,
season to taste and, if required, pass it through a
strainer.
No preheating is required. Save energy by putting
the roast into the oven while it is still cold.
Roasting in a covered pot Place the meat into the roasting pot (or Dutch oven),
cover it with a matching lid, and place it on the wire
shelf in the oven. We recommend that beef roast be
prepared in a covered roasting pot.

We recommend using the lower of the stated
temperatures first.
In general, the lower temperature ensures a more
even browning.
We recommend turning the roast after half or two
thirds of the roasting time have elapsed.
For roasting, use only cookware with oven-proof
handles.
Prepare large roast directly in the universal pan,
without using the wire shelf.
Smaller cuts of meat can be roasted on aluminium
foil. To do so, bend the edges of the foil upward, as
if to form a dish, and place it on the wire shelf.
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.
