according to instructions in section 'Cleaning'.
2. Plug the appliance into a suitable single socket.
3. Prior to first use, and observing instructions in section 'Settings parameters for
the process of cooking/roasting', heat up the oven without food to eliminate
any unpleasant odours that come from the thermal insulation. Select the highest
temperature and the longest time.
A small amount of smoke or unpleasant odour may be produced. This is normal
during first use and should not recur.
4. Next, open the glass pane door to allow all the smoke to escape.

Settings parameters for the process of cooking/roasting
Temperature
The precise temperature setting provides for correct cooking/roasting of foods, both
on the outside as well as in the inside.
When the temperature is too low, the foods are more dried than roasted.
On the other hand, too high a temperature may lead to burning foods from the
outside, while they remain raw in the inside (a phenomenon that is, at times,
desirable especially with meat).
Time
This variable depends on the amount of food that is prepared.
The more food, the longer cooking/roasting time, and vice versa.
If a thermal processing duration is too short in comparison to the recommended
times, it is not possible to prepare food completely; if a thermal processing duration
is too long in comparison to the recommended times, the food gets burned on the
outside.
Amount
The amount of food conditions the thermal processing duration. More food requires
also longer thermal processing times, and vice versa.
Steaming
Steaming (steam generation) is initiated through pressing of the steaming button on
the control panel. When pressed, water is jet-sprayed onto the fan, and then
changes into steam the appliance's oven chamber.
The steaming indicator light is on.
Water is sprayed into the roasting chamber as long as the steaming button remains
pressed-on.
NOTE!
It is enough to press the steaming button shortly (max. 3 s), as otherwise
excessive water accumulates at the bottom of the convection oven.

Installation and operation
A120788 17 / 28

Rules for cooking/roasting
Cooking/roasting in the convection oven with fan-forced air circulation
Cooking/roasting process is effected with the use of hot air circulation inside the
appliance. This makes homogeneous cooking/roasting possible thanks to uniform
temperature distribution.
The benefit of the convection oven is the fact that you may cook/roast various foods
(provided the temperature of processing is the same), and different aromas of the
foods do not mix.
NOTE:
Prior to each use, heat the convection oven properly. Set the temperature
approx. 30°C above the required temperature and correct it when food is
put into the oven in order to obtain uniform effect.
1. Switch the appliance on with the use of the main controller/time controller (rotate
it clockwise and set the required cooking/roasting time).
The green operation indicator light lights up, the internal lighting and fan motors
start right after the main controller/time controller is operated.
2. Set the desired temperature within the range of 50 °C –300 °C with the
temperature controller.
The green heating indicator light will be on.
As soon as the set temperature is reached, the green indicator light goes off and
lights up again, when the temperature in the oven chamber drops.
3. When the set temperature is reached, put the food products in suitable
containers or on oven sheets for baking/roasting into the oven chamber of the
convection oven.
You can place 4 oven sheets on 4 bearing rails of the convection oven at a time.
When filling the appliance with food products, make sure that there is a top
clearance of at least 40 mm between dishes and oven sheets, which will allow for
maintaining optimum heat distribution in the oven chamber.
When the set time has elapsed, an audible signal will be heard, the green operation
indicator light goes off and the appliance switches off automatically.
4. Remove the prepared food from the oven.
5. When the appliance is not to be used any more, switch it off (rotate the main
controller/time controller to '0' position). Disconnect the appliance from the
mains socket (pull the plug out).
Grilling process with power setting

Installation and operation
18 / 28 A120788
EN
The grilling process is carried out with the use of heat radiation of the lit up heating
element. The temperature generated by the IR radiation is very high, and the heat is
dissipated in one direction only (from top to bottom), thus this allows for instant
browning of the surface of food products.
NOTE!
The grill function may be used only independently. The hot air function
must be switched off, as these two functions may not be executed
concurrently!
The power of the grill heating element may be controlled and set between minimum
and maximum values, to obtain the expected browning level —from golden to
brown.
The grill function should be executed with convection oven door closed, so as to
avoid the escaping of odours and smoke.
1. Switch the appliance on with the use of the main controller/time controller (rotate
it clockwise and set the required cooking/roasting time).
The green operation indicator light lights up, the internal lighting and fan motors
start right after the main controller/time controller is operated.
2. Use the middle temperature controller for the grill function to set the grill
temperature (up to 300°C).
The green grill function indicator light lights up.
As soon as the set temperature is reached, this indicator light goes off and lights up
again, when the temperature in the oven chamber drops.
3. Prepare food products for grilling (meat, fish, vegetables) and place them on the
right grill grate.
4. Apply small amount of oil onto the food products.
5. When the set temperature is reached, slide the grill grate with food products
onto the highest level of the convection oven.
6. Insert the fat collecting tray under the grate.
7. Observe the grilling process all the time, as the heating element's heat radiation
has very high values and food products may get burnt easily.
8. When the top surface of the products is browned, open the convection oven
door, remove the grill grate, turn the food products and reinsert the grill grate
into the convection oven, so that the food products are grilled from both sides.
9. After the grilling process, remove the prepared dishes.
5. When the appliance is not to be used any more, switch it off (rotate the main
controller/time controller to '0' position). Disconnect the appliance from the
mains socket (pull the plug out).
