SPECIAL FUNCTIONS
EMPTYING THE STEAM GENERATOR
(Fig.3 No.23)
The appliance is fitted with a motor-operated discharge
valve. Under normal conditions it is closed and this is shown
by 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.
CLEAN (Fig.3 No.24)
The ”CLEAN” programme is a cleaning, not a cooking
programme. It should be activated regularly at the end of a
working day with the air-o-steam
®
in order to clean the
appliance.
To activate this programme, press the button for about 3
seconds, after which the relative indicator light stops blinking
and remains on. The steam generator starts heating and
the cooking chamber is humidified. After the audible warning
signal, a detergent has to be sprayed onto the walls of the
cooking chamber including the air baffle sheets. Close the
door and press the ”CLEAN” button again. The countdown
of the action time for the detergent, i.e. 10 minutes, starts.
After this, restart the steam generator and let it operate for
another 20 minutes, during which all deposits are removed.
The indicator light comes on during the second stage. An
acoustic signal is activated at the end of the programme.
WASTE STEAM QUENCHING SYSTEM
(Fig.3 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 the water input control governed by a
thermostat allows the vapours to be condensed.
After water input, the relative indicator light comes on.
MANUAL HUMIDIFICATION (Fig.3 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.
COOKING CHAMBER STEAM RELEASE
VALVE (Fig.3 No.27)
The steam release valve usually fitted in this version is
motor-operated. It opens automatically by pressing on this
button. During the opening stage the relative indicator light
above the button blinks. Upon completion of opening, the
indicator light stops blinking and remains fixed. To close,
just press the button again.
During the closing stage, the indicator light blinks and goes
out when the valve is fully closed.
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.3 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.3 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.3 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.
