WARNING!
Risk of burns!
During operation, the housing and glass pane door become very hot
and remain hot for a while after switching the appliance off.
Do not touch the appliance during operation nor immediately after
switching it off. Open and close the convection oven using the glass pane
door handle only.
To operate the appliance, use handles and elements designed to this end.
The grate, the tray and containers heat up considerably during
operation.
For removing hot food use dishwashing cloths or kitchen mitts.
Preparation of the Appliance
1. Prior to operation, clean the appliance and its equipment inside and outside
according to instructions in section 6“Cleaning”.
2. Prior to first use, and observing instructions in section “Settings”, 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.
3. Next, open the glass pane door to allow all the smoke to escape.

Food Preparation
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. When the set temperature is reached, put the food into the baking chamber on
trays.
2. If needed, set the time and temperature again.
At a time, 4 baking sheets on 4 guide rails of the convection oven may be inserted.
During packing of the appliance, make sure that there is a top clearance of at least
40 mm between dishes and baking sheets, which will allow for maintaining optimum
heat distribution in the baking chamber.
When the set time elapses, the acoustic signal sounds, which is repeated until it is
confirmed by pressing one of the two push rotary control knobs.
The indicator light of the push rotary control knob goes off.
3. Remove the prepared food from the oven.
4. When the appliance is not to be used any more, it should be switched off with
the ON/OFF switch.
5. Disconnect the appliance from the socket (pull the plug out).
Overheating protection
The appliance is equipped with overheating protection, which activates at 320 °C
and disconnects the appliance.
When the overheating protection is activated:
–Leave the appliance to cool off for some time.
–Press the RESET button at the rear side of the appliance.
–Restart the appliance.

Rules for cooking/baking
Baking in the convection oven with fan-forced air circulation
Cooking/baking process is effected with the use of hot air circulation inside the
appliance. This makes homogeneous cooking/baking possible thanks to uniform
temperature distribution.
The benefit of the convection oven is the fact that you may cook/bake various foods
(provided the temperature of processing is the same), and different aromas of the
foods do not mix.
Variable parameters of cooking/baking
Temperature
The precise temperature setting provides for correct cooking/baking of foods, both
on the outside as well as in the inside.
When the temperature is too low, the foods are more dried than baked or 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/baking 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.
Thermal processing methods
Main Courses
Lasagne, pasta gratin, and cannelloni should be baked in the temperature of 185 °C
–190 °C. To obtain yellowish-gold crust, increase the temperature to 220 °C - 230 °C
at the end of the baking process.
Roasting
Beef, pork, chicken, turkey, lamb. To roast the meat, the roasting process requires
the temperature of 180°C. In the final phase, to dry the meat, set the temperature to
240 °C –250 °C for a couple of minutes.

Installation and operation
18 / 26 A120796
EN
Meat browning
Chop, cutlet, sausage, hamburger.
Extend the grate with the products for roasting, which are slightly smeared with oil.
Insert a fat collecting tray under the grate. Roast in the temperature of 220 °C –
230 °C. In the final phase increase the temperature to 280°C for a couple of minutes,
to have the food browned a bit.
Roast beef
Bake in the temperature of 220 °C.
Fish
Roast plaice, cod, and hake in the temperature of 200 °C.
Baked potatoes
Bake in the temperature of 170 °C –180 °C.
Pies
As a rule, bake in the temperature of 180 °C. During baking, avoid opening the door
of the convection oven.
Bread
Bake in the temperature of 200 °C.
Thermal processing of deep frozen products
Defrost the frosted bread in the temperature of 200 °C.
Insert a pre-roasted, frozen pizza into the convection oven in a frozen state and
roast in the recommended temperature for a couple of minutes. Follow the
manufacturer’s instructions on the packaging.
Buns/Toasts
Heat up in the temperature of 220 °C.
Heating up food
Prepare food in the temperature of approx. 150 °C.
Defrosting food
Defrost in the temperature of 80 °C.
