Another pressing of the push/rotary temperature control knob the program is re-activated and continued with the set parameters.

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 in suitable GN containers or on trays.

2. If needed, set the time and temperature again.
   You can place 4 baking trays or 4 GN containers on 4 guide rail pairs of the convection oven at a time. During packing of the appliance, make sure that there is a top clearance of at least 40 mm between food and trays or GN containers, 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.

5. Disconnect the appliance from the socket (pull the plug).

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.

• 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.
