• Turn off the device;
• Switch the light on;
• Fan only
• Circulation fan

• Grill

• When the function dial is set to the OFF position, the convection oven is completely off.

• When the function dial is set to FAN ONLY, the lights and fan work. The convection oven heating system is turned off in this setting.
• When the function dial is set to CIRCULATION FAN, the lights and fan work. The convection oven heating system is enabled in this setting and can be controlled by turning the temperature dial. The heater in form of a circle around the fans. However, the grill heating element is turned off.
• When the function dial is set to GRILL, the light is on. The convection oven heating system is ready for operation in this setting and can be controlled by turning the temperature dial. The grill heating element is turned on. However, the heating element around the fan is turned off.

ON/OFF LED

When it is on, it indicates that the cooking compartment lighting is switched on and the heating elements are ready to use, depending on the selected function.

Timer dial

If you set the dial to constant mode the convection oven will remain on until the user does not intervene.

If a specific value is selected in the range up to 120 minutes, the convection oven is constantly switched on for this time period. After the set time, the device turns off..

Temperature control dial

Temperature adjustment knob allows you to select the desired heating temperature in the range from 0 °C to max.(280 °C).

Thermostat LED

This light is on when the convection oven heating elements are turned on, and the cooking temperature is lower than the set temperature by turning the temperature setting.

When the light goes off, it means that the heating elements turn off and reached the set temperature.

Humidification control dial

Humidification is used for more delicate cooking all kinds of food. Moreover, this option is suitable for rapid defrosting, heating of food without drying them, and natural food placed desalination of salt.

The combination of wetting and traditional function allows the flexibility and at the same time saving energy and time. At the same time are stored nutritional and taste of food. Injected water is sprayed on the fan, and - thanks to the high temperature in the cooking compartment - changed into steam.

NOTE: To humidify work in a satisfactory manner, it is necessary that the temperature was set to at least 80 - 100^ C .

For lower temperatures arises only serious couple, and a large part of the water flows to the bottom of the convection oven or drain.

In addition, the required proper cooking convection oven pre-heated to the desired temperature before it is activated humidification.

Dial setting allows you to activate humidification. It can be adjusted in the range from 1 to 10 by turning the dial in a clockwise direction.

Humidification indicator

If it is enabled it means that the water enters the chamber in order to produce steam. This is done regardless of the temperature (the operator must ensure a sufficiently high temperature to cook properly).

Steam injection button

This button activates steam injection when pressed.

Thawing

- convection oven can be used to accelerate the defrosting process for cooking meals, with the fan at room temperature or below (depending on the size and type of product for thawing). In this way, you can quickly thaw the products without losing their flavour or changes in their appearance.

Preheating

- In order to compensate for the effects of heat loss through the opening of the oven door for inserting food into convection oven, it is recommended that pre-heating at a temperature of at least 30^ C above cooking temperature provided.

Hints and Tips

• Cooking extremely fat foods with the use of the grill, such as roasts or poultry, we recommend placing a container on the bottom of the cooking chamber in order to catch the dripping fat.
• Cooking in containers filled with liquids be particularly careful to avoid spilling the liquids out of the containers both during cooking and removing containers from the oven convection. Risk of burns!
• If the ovens are placed above proofers, stainless steel tables or other ovens it is not advisable to use the upper surface to insert the GN containers so that the user could look into the containers. Risk of burns!
• For perfect and even cooking of meals we recommend using not too tall containers to ensure good and sufficient air circulation. A minimum distance between the upper container and the meal shall be at least 2 cm.
• Do not overload the convection oven in order to obtain a uniform effect when baking cakes or bread; try to arrange the products following the direction of air circulation in the cooking chamber.
• Proper use of the internal temperature probe: insert in the thickest point of the food product from the top to the bottom until you the tip of the probe reaches the product centre.
• If during cooking you need to handle the food product, open the convection oven door for as short time as possible to prevent a too large drop in temperature inside the convection oven because that could adversely affect the outcome of your cooking.

NOTE!

We recommend opening the door gradually: keep it mid open (3-4 cm) for 4-5 seconds, and then fully open. This way you can avoid the defects and burns caused by fumes and high temperature in the convection oven.
