5.1 Safety instructions
WARNING! Risk of electric shock!
The device must only be connected to a properly installed single socket with
protective contact.
Never remove the power cable by pulling the cable itself; always grab the plug
housing.
• Never allow the power cable to come into contact with heat sources or sharp edges.
The power cable should not hang over the side of the working surface. Ensure that no
one can step on or trip over the cable.
• The power cable must not be folded, bent or tangled, and must always remain fully
unrolled.
• Never place the device or other objects on the power cable.
• Do not lay the cable over carpets or heat insulations. Do not cover the cable. Keep
away the cable from operating range and do not dunk it into water.
• Do not use the device in case it does not function properly, has been damaged or
dropped.
- 26 -
• Do not use any accessory or spare parts that have not been recommended by the
manufacturer. These can be dangerous for the user or lead to damages of the
device or personal injury, and further, the warranty expires.
• Do not move or tilt the device when in operation.
• Never use the device with wet or moist hands.
• Never leave the device unattended when in use.
WARNING! Hazard via electrical current!
The device can cause injuries due to improper installation!
Before installation the local power grid specification should be compared with
that of the device (see type label).
Connect the device only in case of compliance!
Take note of the security advice!
5.2 Installation and connection
ATTENTION!
Any installation, maintenance and repair work should be executed only by an
authorized installation engineer!
• Unpack the device and dispose adequately all packaging material.
• Mount the adjustable feet to the device and set the desired height by screwing the
feets in or out. Do not use the device without installing the adjustable feet.
• Remove carefully the protective film from the outside walls so as to avoid adhesive
residues be left. If any adhesive residues remain, remove them with a suitable
solvent.
• Place the device on a flat, safe surface which can withstand the weight of the device
and is not heat sensitive.
• Never place the device on an inflammable surface.
• Do not place the device near open fireplaces, electric ovens, heating stoves or other
heat sources.
• Place the device so that the rear ventilation holes were not blocked or covered.
• Do not place the device near walls or other objects made of combustible materials.
Keep a minimum distance of 10 cm on all sides.
• Do not place any objects on the device.
- 27 -
NOTE!
The device is not suitable for built-in installation and series arrangement!
• The electrical circuit of the socket must be secured to at least 16A. Only connect
the device to a wall outlet; do not use any extension cords or power strips.
• Place the device so that the plug is easily accessible so as to quickly disconnect the
device if the need arises.
5.3 Operation
Preparation of the device
• Clean the device before start-up from inside and outside with a soft damp cloth and
mild detergent. Rinse it thoroughly with clean water.
• Before first use, heat up the device without food, in accordance with the instructions
contained in the chapter "Settings", to eliminate any unpleasant odors that come from
the thermal insulation. Choose the highest temperature and the longest time. A little
smoke or an odor may be generated. This is normal for the first operation and will not
happen again during subsequent use. Then open the glass door so the smoke
residues can escape.
• Clean the baking trays and grill grate with mild detergent. Rinse them with clean
water and then dry with a soft dry cloth.
Settings
NOTE!
Heat up the convection oven well before each use. Set the temperature about 30 °C
higher than the specified one and correct it after charging the convection oven,
which will help you to achieve an even result.
• Turn the device on by means of main / time control knob (rotate it clockwise to the
desired cooking time). Once you activate the knob, the green operation control lamp
will illuminate and the interior lights as well as the fan motors will be turned on.
• Set the desired temperature using the temperature control knob.
The green heating control lamp will illuminate. Once the set temperature is reached,
the green control lamp goes off and lights up again when the temperature in cooking
cavity decreases.
- 28 -
• After reaching the set temperature, place the desired food in cooking cavity of
convection oven.
WARNING! Risk of burns!
Some parts of the device become very hot during operation.
Always open and close the convection oven with the help of door handle.
Use protective gloves when you operate the device.
• There can be placed 4 baking trays in four slide rails of the convection oven at the
same time. When charging the device keep at least 40 mm distance between the
food and the baking tray above it, in order to maintain optimum heat distribution in
the cooking cavity.
• After the preset time elapses a signal sounds, the green time setting lamp goes off
and the device automatically switches off.
• Remove the cooked food.
• If the device is no longer used, turn it off (set the main / time control knob and
temperature control knob to the "0" position) and disconnect it from the power
supply (pull the plug!).
ATTENTION!
The device is equipped with an overheating protection device, which trips at
320 °C and shuts down the device. If the overheating protection device has
tripped, let the device be cooled for some time and press the RESET button at
the rear of the device to bring it back into operation.
Rules for the roasting/baking process
Roasting process in a convection oven with air circulation
The roasting process in a convection oven is realized with the recirculation of hot air inside
the device. This allows even roasting/baking due to uniform temperature distribution.
The advantage of the convection oven consists in the fact that the different dishes can be
roasted/baked at the same time (when the cooking temperature is the same), without the
risk of mixing different flavors.
- 29 -
Variable parameters during roasting/baking:
temperature
time
amount
Temperature
A precise temperature adjustment guarantees proper roasting/baking of dishes, both on
their outer part as well as inside them.
Too low temperature causes rather drying of food than its roasting.
Too high temperature, however, can lead to burning of the food on the outside, and the
interior still remains raw (a phenomenon that is sometimes desirable, especially in case
of meat).
Time
This variable depends on the amount of food which are to be prepared.
The larger the amount is, the longer the roasting/baking times and vice versa.
Too short cooking times compared to the correct ones do not allow for full preparation of
food; too long cooking times compared to the correct ones lead to burning of food on the
outside.
Amount
The amount of food affects the cooking time. A larger amount of food always leads to
longer cooking times and vice versa.
Use of baking molds/grill grate
It is recommended to use:
Baking molds of aluminum for pastries and non-frozen bread,
Baking molds of steel for starters, meat, fish, potatoes,
Grill grate for roasting of meat (such as steak, sausages,
bratwursts), frozen products (eg pizza, rolls,
baguettes).
NOTE!
Use only heat-resistant roasting tins or baking molds. Pay attention to the
instructions of the manufacturer!

5.4 Cooking methods
First dishes
Lasagne, pasta bake, Cannelloni should be cooked at a temperature between 185 °C 190 °C. In order to achieve a golden yellow crust, the temperature at the end of
cooking process should be increased to 220 °C - 230 °C.
Roasting
Beef, pork, chicken, turkey, lamb. Run the process at a temperature of 180 °C to
ensure that the meat is thoroughly roasted. In the final phase, the meat should be
scorched for a few minutes at a temperature of 240 °C - 250 °C to dry out.
Browning of meat
Chop, steak, sausages, hamburgers.
Insert the grill grate together with food to be roasted, slightly smeared with oil. Slide a
drip tray under the grill grate. Roast at 220 °C - 230 °C. In the final phase increase
temperature to 280 °C for a few minutes so that the dishes be slightly browned.
Roast beef
Roast at a temperature of 220 °C.
Fish
Roast plaice, cod, hake at a temperature of 200 °C.
Roast potatoes
Roast at a termperature of 170 °C -180 °C.
Pastries
Normally, carry out baking at a temperature of 180 °C. Avoid opening the convection
oven door during the baking process.
Bread
Bake at a termperature of 200 °C.
Cooking of frozen products
Let the frozen bread defrost and bake it at a temperature of 200 °C.
Pre-baked, frozen pizza should be slid into the hot oven in still frozen state and be
baked at a given temperature for a few minutes. Follow the instructions of the
manufacturer on the packaging!
