2 - FITTING
2.1. - Build-in the oven
The oven has a high-performance air flow system which gives remarkable results as long as the
following points are applied:
•The oven may be fitted either underneath a work top or in a suitable sized column unit.
•Cut a hole measuring 50 mm x 50 mm in the back wall of the insert space for the electric cable to
cross through (see diagram below).
•Centre the oven in the unit, and make that it is at least 2 mm from any other unit beside it.
•The oven must be disconnected from the power supply while it is being installed in the unit
•For greater stability, fix the oven in the unit with 2 screws in the holes on the side uprights.

INSTALLATION
2.2. - Electrical connection
For a permanent connection, make sure an all-pole switch is placed into the supply line with a contact
distance of at least 3mm. The appliance must be placed in such a way as to leave the plug accessible
if it is flush-fitted.
Use of an earthed power socket, connected in compliance with current safety standards
The installation must be fitted with a 16 amp device for thermal protection.
Do not use the oven if the supply cord or its plug are damaged.

USING
3 - USING
3.1. - Setting the time
¾The first time the oven is turned on
•The display flashes on12.00
•Use the +and -buttons to adjust the time.
•Validate with SET (Validation is automatic after few seconds).
¾Changing the time
•Press on the + and - buttons simultaneously until the time starts to flash.
•Adjust the time using the + and - button.
•Validate with SET (Validation is automatic after few seconds).
3.2. - Possible functions
•Standard steam cooking: Temperature 100°C
•Defrosting : Temperature 60°C
•Independent timer: Accessible by the ‘SET’ button.
3.3. - Locking the control panel
The control panel can be locked. This can only be activated when you are not using timed or delayed
cooking features.
¾To lock
•Hold down the START/STOP button for a few seconds.
•A beep sounds and a “key” appears on the screen. From this moment, no button is live.
¾To unlock
•To unlock, hold down the START/STOP button for a few seconds. A beep sounds and the key
disappears.
3.4. - Cleaning the channel
Dismantle this channel by pulling upwards. Wipe it and replace it,
using the three notches provided for this purpose.

PRINCIPLE
4 - GENERAL PRINCIPLE
The water contained in a removable tank is brought by an electrovalve on a heat generator where it is
transformed into steam. The steam obtained is maintained in the oven cavity by closing a flap.
This flap is bored several holes in order to avoid the pressurization of the cavity.
This cooking principle is different to a pressure-cooker where the obtained pressure is higher than the
atmospheric one.
Initially the oven will be saturated with steam and the temperature will be close to 100°C. In order to
avoid condensation, an electric blanket which covers the top will be supplied during all cooking time.
Tangential fan allows the constant cooling of the oven and the extraction of the steam when the flap
opens three minutes before the end of the cycle. A safety thermostat (210°C) protects the oven against
overheating. Two probes located in the cavity and in the generator allow the temperature control.

COOKING STEPS
5 - STUDY OF THE COOKING CYCLE
Cooking is divided into 5 steps.
¾Rise in the temperature and steam generation (Step 1)
Immediately after starting, the valve, the tangential fan, the heater, the electric blanket and the thermal
activator are supplied. The steam generation is important in order to quickly obtain saturation in the
cavity. The valve is supplied by step of 15 to 30 sec as soon as the generator temperature exceeds
130°C.
¾Upholding of the steam level (Step 2)
The heat generator is regulated by the probe. The thermal activator, the electric blanket and the
tangential fan are still supplied.
¾Steam emptying and temperature decreasing (Step 3)
Three minutes before the end, the thermal activator and the electrovalve are not supplied any more.
The flap opens, the tangential air flow involves the steam out of the cavity. The electric blanket is
always supplied.
¾Keep warm (Step 4)
This step takes place only if the door remains closed after the end of cooking. The tangential and the
electric blanket are always supplied. The maximum duration: 1 hour.
¾Cavity drying (Step 5)
This step starts as soon as the door is open or after 1 hour and continues during 3 minutes. The
tangential and the electric blanket are supplied.

Designation Function Characteristics
Water tank The tank must be
•Full of water before each cooking.
•Emptied after each cooking
In case of too hard water, it’s better to
use a noncalcareous water.
The use of demineralized water is
disadvised.
•Capacity: 1 litre
Electrovalve The electrovalve supplies the
generator in water

Door switch This switch allows to modify the cycle
when the door is open.
Door open= Switch is off
Door closed = switch is on
Heat generator
(upside down view)
The generator transforms water into
steam. It is made to receive back the
condensations at the time of cooking.
2 security thermostats (KX1 and KX2),
located underneath, protect against
overheating (T°C: 210°C).

•1600 W
•35 Ω
Electric blanket During all cooking, the electric blanket is
supplied in order to avoid any risk of
condensation. It covers the top of the
cavity. Its temperature is close to 100°C.
It is protected by a thermal fuse.
