the indicator light above the symbol going out.
Upon pressing the button the valve opens so that the water
inside the steam generator can drain off. This operation is
shown by the relative indicator light coming on. Once the
boiler has been drained the button must be pressed again
to close the valve.
WASTE STEAM QUENCHING SYSTEM
(Fig.2 No.25)
This button can be used to activate or deactivate the
thermostatic waste steam quenching system in all the
cooking modes. If the air-o-steam
®
is placed under a steam
extraction hood, the steam need not be condensed by
spraying cold water into the waste tube. This saves on
water. Upon pressing this button, the relative indicator light
above the symbol starts blinking, showing that the steam
condensation device is deactivated.
By pressing the button again, the system is re-activated in
normal condition and depending on whether water is being
injected or not, the relative indicator lights up constantly or
goes out.
MANUAL HUMIDIFICATION (Fig.2 No.26)
This button may be used to increase the degree of humidity
inside the cooking chamber by introducing water. The water
input time is limited to about 5 seconds.
The relative indicator light is on during water input. The
degree of humidity in the cooking chamber may be altered
to individual requirements by pressing this button several
times.
Three circular indicator lights, placed in the lower part of
the control panel, are indicating the following control
functions.
WARNING OF SCALE BUILD-UP IN THE
STEAM GENERATOR (Fig.2 No.28)
When the indicator light relating to the symbol comes on,
this means that there is a build-up of scale in the steam
generator and on the heating elements. Descaling should
be carried out as quickly as possible.
Detailed instructions for chemical descaling of the entire
system are given in the chapter ”Cleaning and care”.
DOOR SAFETY (Fig.2 No.29)
If the indicator light relating to this symbol comes on, the
door is not closed properly and consequently the ”STEAM”
and ”STEAM 1” cooking modes cannot be activated.
STEAM GENERATOR LEVEL GAUGE
(Fig.2 No.30)
The indicator light relating to the steam generator symbol
blinks whenever the water in the steam generator does not
cover the safety level mark.
If the indicator lights up continously, this means that the
steam generator is still being filled with water, the heating
elements, however, can be activated. The steam generator
is ready for use. When the indicator light goes out, this
means that the water level inside the steam generator is
correct and there is no need to top up.

ON/OFF SWITCH (Fig.3 No.1)
The ON/OFF switch is used to switch the appliance and
controls on or off. To switch the appliance on, lightly press
the button; to switch off keep the button pressed down for
about 3 seconds. This time delay avoids accidental
switching off during a cooking cycle.
When the appliance is switched off, this is indicated by
the green indicator light above the button going out. When
the appliance is switched on it lights up.
Note: upon switching off the appliance, wait at least 5
seconds before switching on again.
COOK-STEP (Fig.3 No.5)
With this COOK-STEP storage, it is possible to divide a
cooking cycle into two different sequences: e.g. browning
and finishing the cooking of the roast. The two COOK-
STEPS are indicated by the two-coloured indicator lights.
The lighting up of a red indicator light indicates, that the
relevant COOK-STEP is just being programmed or that it
is already working. The other STEP which actually is not in
operation is shown by a green indicator light.
The first COOK-STEP is always activated automatically
in the neutral position of the control, which is indicated by
the lighting up of the left indicator light in red and the right
indicator light, symbolizing the second cooking stage, in
green. As soon as the first COOK-STEP is memorized
(e.g. cooking chamber temperature in the hot air mode and
a certain time for the initial roasting stage), it is possible to
activate the second stage by pressing the button and then
proceed with a new programming (e.g. cooking chamber
temperature in a combination mode and a certain cooking
time for the final roasting) .

STOP
START/STOP (Fig.3 No.3)
After having selected all data necessary for the cooking
process, such as temperature, cooking time, cooking mode
and fan speed, the cooking process may be started using
the ”START/STOP” button. The relative yellow indicator light
comes on.
The cooking cycle may be interrupted by pressing the button
for more than 3 seconds.
HOT AIR (Fig.3 No.11)
In this position only the heating of the cooking chamber is
activated, which means just hot-air operation.
STEAM (Fig.3 No.12)
In this position only the steam generator heating elements
are activated, which means steam operation between
30 - 100°C.
