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.
Before using the oven for the first time, heat it with
the upper and lower heater system at 200 °C for
approximately one hour. The characteristic ”new
appliance” scent will be released; make sure the room is
well ventilated.
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
TESTING WATER HARDNESS
Water hardness test should be carried out before first use.
A warning will appear on the display: ”Use the test paper to measure water hardness.”
Soak the test paper strip (supplied with the
appliance)in water for one (1)second.
Wait one minute and observe the number of stripes
on the paper. Enter the information on the number
of stripes into the appliance. Rotate the KNOB and
confirm the selection with the CHECK MARK.
4 green stripes Soft
1 red stripe Slightly hard
2 red stripes Medium hard
3 red stripes Hard
4 red stripes Very hard
The highest water hardness is set as a factory default.
CHANGING THE WATER HARDNESS SETTING
Water hardness can also be set in the menu CHOOSING THE GENERAL SETTINGS.
If the correct water hardness level is not set, this could
affect appliance operation and its useful life.

12
FILLING THE WATER TANK
The tank allows for independent water supply to the steamer. The tank volume amounts to approx. 1.3 litres (maximum
water level –see marking). This amount of water allows approximately 3 hours of cooking time with max. steam cycle (hot
air with steam on ”high” system).
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.
1Press on the spot with the sticker to open the tank
door.
The sticker can be later removed.
2Remove the water tank from the housing by grabbing
the notch.
3Open the lid. Wash the tank with water. Re-assemble
the tank. Before use, add fresh water up to the MAX
marking on the tank.
4Push the water tank back into the housing to the final
position (until the short click). Then, press the tank
door to close it.
After the cooking process, the remaining water in the
steam system is pumped back into the water tank. The
lid and the water tank can be washed with standard non-
