(DESCRIPTION OF THE OVEN AND EQUIPMENT – DEPENDING ON THE MODEL)
The figure represents one of the built-in appliance models. Since the appliances for which these instructions were drawn
up may have different equipment, some functions or equipment may be described in the manual that may not be present
in your appliances.
TECHNICAL SPECIFICATIONS
(DEPENDING ON THE MODEL)
The rating plate indicating the basic information about
the appliance is located at the edge of the oven and it is
visible when the oven door is opened.

WIRE GUIDES
The wire guides allow preparation of the food on 4 levels
(please note that the levels/guides are counted from the
bottom up).
Guides 3 and 4 are intended for grilling.
TELESCOPIC GUIDES
Telescopic pull-out guides may be fitted for the 2nd, 3rd,
and 4th level.
There are several different designs of the pull-out guides
(depending on the model):
three partially extendible, one fully and two partially
extendible, and three fully extendible guides.
OVEN DOOR SWITCH
The switches deactivate oven heating and the fan when
the oven door is opened during the cooking process.
When the door is closed, the switches turn the heaters
back on.
COOLING FAN
The appliance is fitted with a cooling fan that cools the
housing and the appliance control panel.
EXTENDED OPERATION OF THE COOLING FAN
After the oven is switched off, the cooling fan continues
to operate for a short while in order to cool the oven.
(Extended cooling fan operation depends on the
temperature in the center of the oven).
OVEN EQUIPMENT AND ACCESSORIES
GLASS BAKING DISH is used for cooking with all oven
systems. It can also be used as a serving tray.
The GRID is used for grilling or as support for a pan,
baking tray or baking dish with the food.
There is a safety latch on the grid. Therefore, the
grid has to be lifted slightly at the front when pulling it out
from the oven.
The SHALLOW BAKING SHEET is used for baking
pastry and cakes.
The DEEP BAKING TRAY is used for roasting meat and
baking moist pastry. It can also be used as a drip tray.
Never place the deep baking tray in the first guide
during the cooking process, except when grilling food or
using the roasting spit and you are only using the deep
tray as a drip tray.
PERFORATED DEEP TRAY is used for cooking
vegetables, potatoes, fish or meat. The tray prevents
contact between the food and condensate collected in
the deep tray.
When using the perforated tray, always place the
deep tray underneath it. This combination is only used
for steam cooking on the 2nd guide.
The grid or the tray should always be inserted into the
groove between the two wire profiles.

6
With telescopic extendible guides, first pull out the
guides of one level and place the grid or the baking tray
onto them. Then, push them in with your hand as far as
they will go.

the appliance. Cleaning and user maintenance shall not be made by children without
supervision.
WARNING: The appliance and some of its accessible parts may become very hot during
use. Be careful not to touch the heaters. Children younger than 8 years should be constantly
supervised.
The appliance becomes very hot during use. Be careful not to touch the oven heaters.
WARNING: The accessible parts of the appliance may become hot during use. Children
should be kept away from the oven.
Only use the temperature probe recommended for use in this oven.
WARNING: Before replacing the light bulb, make sure the appliance has been disconnected
from the power mains, in order to prevent the hazard of an electric shock.
Do not use abrasive cleaners or sharp metal scrapers to clean the oven as they may damage the
finish or the protective enamel coating. Such damages may lead to cracking of the glass.
Do not use steam cleaners or high pressure cleaners to clean the appliance as this may result in an
electric shock.
The appliance is not intended to be controlled with external timers or special control systems.
The appliance is intended for household use. Do
not use it for any other purpose, such as room heating,
drying of pets or other animals, paper, fabrics, herbs etc.
as this may lead to injury or fire hazard.
The appliance may only be connected to the power
mains by an authorized service technician or expert.
Tampering with the appliance or non-professional repair
thereof may result in risk of severe injury or damage to
the product.
If the power cords of other appliances located near

bottom. Aluminium foil would prevent air circulation
in the oven, hinder the cooking process, and ruin the
enamel coating.
Oven door become very hot during operation. A
third glass is installed for extra protection, reducing
the temperature of the outside surface (only with some
models).
Oven door hinges may be damaged when under
excessive load. Do not place heavy pans on open oven

any other way.
IMPORTANT SAFETY INSTRUCTIONS

Safe and correct use of the steam oven
Leave the appliance at room temperature for some
time before connecting it to the power mains to allow all
components to adapt to room temperature. If the oven
is stored at a temperature near or below freezing point,
there is a danger for some components, especially the
pumps.
The appliance should not operate in an environment
with a temperature below 5 °C. Below this temperature,
the water that remains in the pumps could freeze. If the
appliance is turned on in such conditions, the pumps
could be damaged.
If the appliance does not work correctly, disconnect it
from the power mains.
Do not store items in the oven, which could cause
danger when the oven is switched on.
Do not use distilled water that is not suitable for
ingestion.
After the steam cooking is completed, there is some
residual steam in the oven. Open the oven door carefully,
as there is danger of scalding with steam.
Clean the oven once it has cooled down to room
temperature.
After the cooking process, the remaining water in the
steam system is pumped back into the water tank.
Therefore, the water there could be hot. Be careful when
emptying the water tank.
To prevent the build-up of limescale, leave the oven door
open after cooking to allow the oven cavity to cool down to
room temperature.
BEFORE CONNECTING THE OVEN:
Carefully read the instructions for use before
connecting the appliance. Repair or any warranty
claim resulting from incorrect connection or use of the
appliance shall not be covered by the warranty.

10
After receiving the appliance remove all parts, including
any transport equipment (cardboard and polystyrene
inserts), from the oven.
Clean all accessories and utensils with warm water and
regular detergent. Do not use any abrasive cleaners.
When the oven heats up for the first time, the
characteristic smell of a new appliance will be emitted.
Ventilate the room thoroughly during the first use.
STEAM COOKING
Healthy and natural, steam cooking preserves the full
flavour of foods. This cooking method releases no
odours. There is no need to add salt to the water or to
add herbs and spices.
Following are the advantages of steam cooking:
Cooking (braising, roasting)starts before the
temperature inside the oven reaches 100 °C. Slow
cooking (braising, roasting)is also possible at lower
temperatures.It is healthy: vitamins and minerals are
well preserved because only a small share of them is
dissolved in the condensation water that touches the
food.
There is no need to add any fat during the cooking
process. The steam maintains the taste of food. It does
not add odours, nor the taste of the grill or the pan.
Furthermore, it takes nothing away because the food
is not diluted in the water. Steam does not spread the
flavour or smell; therefore, meat or fish can be cooked
together with vegetables. Steam is also suitable for
blanching, defrosting and reheating or keeping the food
warm.
BEFORE USING THE APPLIANCE FOR THE FIRST TIME

11
FILLING THE WATER TANK
The tank allows for independent water supply to the steamer. The tank volume amounts to approx. 1.2 litres (maximum
water level –see marking).
Clean the water tank before the first use.
Always fill the water tank with clean and cool water from the
pipeline, bottled water without additives, or distilled water
suitable for use in cooking. Water that is poured into the
water tank should be at a temperature of 20 °C +/- 10 °C.
