You are what
you eat
Feuerbach coined this expression when he reviewed a book
5electrolux user guide
on nutrition in 1850. He was of course right. We are what we eat.
Or we will soon become it... It is therefore important that we eat correctly.
For most of us nowadays the main meal of the day is prepared
in a catering kitchen. So it is even more important than ever
that the food served is appetising and nutritious.
We help make sure this is the case with our new Electrolux Cook and Chill
air-o-system. With our precise (patented) humidity control
and air circulation within the cooking chamber it is now even easier.

Cooking cycles
automatic pre-heat function (removable via software)
There are 3 steam cooking modes,
• Low Temperature Steam where you can select from 25 up to 99 °C
• Normal Steam cooking at 100 °C
• Super Heated Steam from 101 up to 130 °C
Steam cycle
25 °C to 130 °C
Combi cycle
Max. 250 °C
Convection cycle
Max. 300 °C
Steaming is ideal for all foods that can be cooked in water (with exception to
pasta), low temperature steam cooking is perfect for delicate foods, sous – vide
while super heated steam is excellent for frozen vegetables for example.
Electrolux has a unique Humidity Control system called “Lambda Sensor” which
guarantees precise humidity control and when steaming foods this guarantees
100% steam saturation inside the cooking chamber.
This cycle is a combination of Convection and Steam cooking modes
having a maximum temperature of 250 °C. It’s ideal for meat with bone,
example – poultry, ribs, saddle etc. Also stuffed vegetables, lasagne, seafood,
some bakery products and desserts.
Advantages; Reduced cooking and re –heating times, less food shrinkage
meaning higher yields, perfect baking results and with the aid of the
Lambda Sensor you are able to select the perfect humidity level to give
you the best results.
For Proving Dough’s select Combi and a temperature below 50 °C,
we suggest 33deg, you will see “Fer” in the humidity display which means
“Fermenting” and the Humidity level is automatically controlled by the oven. The
fan also runs at a reduced speed for a gentle environment.
This cycle uses dry hot air with a maximum temperature of 300 °C.
We have today 3 types of Convection cooking available, the first is with
the oven’s vent in the closed position, the second is with the vent open and
third we use the Lambda Sensor to keep the humidity level at the optimum
for giving perfect cooking results. The Lambda Sensor is measuring
the humidity coming from the food and does not use steam from the boiler.

Convection cooking is ideal for roasting meats, grilling meats on the oven
grid, au gratin, breads, pastries, fresh or frozen convenience products,
baking and browning.
When selecting a temperature of 300 °C we have a time limit of 10 minutes
after which the oven will automatically reduce the temperature to 280 °C.

Useful tips for cooking
with air-o-steam
Cooking modes are simple to select and feature the following:
®
When the appliance is energised (turned on) the digital display will do a self
“lamp” test where by all the display panel will illuminate for a few seconds.
Control panel has very bold illuminated digital display which can be easily read
from up to 11 metres away.
At the end of a cooking cycle “END” appears and flashes to let the operator
know the cooking cycle has ended, This is very important in a busy noisy
kitchen as quite often the operator does not hear the end of cycle alarm and
foods can be over cooked.
Note; Every time a cooking mode is selected, temperature set and either a
cooking time or core temperature target set, when you press the start/stop
button the oven will automatically Pre Heat. If the temperature you have
selected is 130 °C or less the oven will heat up to that set point.
If the temperature you have selected is higher than 130 °C then the oven will
automatically pre heat 20 °C higher to help compensate for the heat loss when
door is opened to load with product.
Note; when oven is not used for some minutes the lights will turn off to save
energy.
Steam mode, When you press this button the temperature display will show
100 °C which is the default setting, If you want either “Low” or “Super heated”
steam then press the temperature button and select any temperature between
25 up to 130 °C.
Combi mode, ( combination of Steam and Convection – dry hot air ). When
you select this cooking mode you will see in the coloured bar the number
50, this is the pre set Humidity level. If you want a different % of humidity
simply push the combi button a second time and using the main control dial
select the level you desire while the number is flashing.
The Humidity level is controlled by a Lambda sensor – Unique to
Electrolux! measuring the REAL humidity within the cooking chamber.
Whether cooking a single portion or full load you are able to control
the level of humidity you desire.
Convection mode – 3 choices.
1.
When selecting convection mode the cycle will operate with “vent closed”
trapping the humidity coming from the food being cooked inside the oven.
This can create some problems regarding “browning” as too much humidity
will make browning – meats in particular – difficult.
19electrolux user guide
air-o-steam
®
Press the convection mode button a second time and you can now select
2.
(using the main control knob) the level of humidity you desire. This is
controlled by a second “inlet vent”. So that when the level of humidity you
have selected is reached (this humidity being “relative humidity”), it is displayed
in blue on the coloured bar together with red (indicating the percentage of
humidity and dry air visually).
The vent will automatically open and being positioned within the circumference
of the oven fan where a negative force (vacuum) is generated, it will allow fresh
air from the kitchen to be drawn into the oven chamber.
This “fresh” air is then blown through the heating elements into the cooking
chamber, which has no detrimental effect on the product you are cooking
(as the air is pre – heated) and which will then force the humidified air out
of the second vent.
Once the level of humidity has been stabilised the vents automatically
3.
close again.
Third choice of Convection cooking is with oven vent open fully during
cooking, this is achieved by entering “advanced functions” and selecting the
open vent symbol which allows a continuous release of humidity from the
oven chamber.
Every time you select a cooking cycle either manually or from the program
library, the oven will automatically “pre-heat” to ensure the correct temperature
is reached prior to loading. If you select a temperature up to 130 °C the
cooking chamber will pre-heat up to that temperature. If you select
a temperature above 130 °C the oven will automatically pre-heat 20 °C higher
to compensate temperature loss when door is opened to load product.
When oven is ready, it will beep and display “LOAD” on the control panel.
After loading the product into the oven, close the door and press the
START
STOP
button to activate the cooking cycle. If you forget this step the oven will
remain on pre-heating and timer will not be activated.
The oven has 100 free spaces for operators to store cooking programs.
P
Plus 4 pre – heating cycles, “baking – roasting – steaming & banquet”
Plus 4 cleaning cycles – soft – medium – strong & extra strong. When
the cleaning cycle has ended and the oven is not touched for two
minutes it will automatically turn itself onto “Standby mode”. All you
will see on the display is “Stby” which means Standby. The only
electrical energy being used is for the LCD screen.
The next time someone touches the oven it will start automatically.
Plus 21 memorised cooking cycles which start with the letter “F” to
denote they are factory set cooking cycles.

The Pause mode can be utilised in several functions
To delay the starting of the appliance (remember that you have 6 phases each
A.
with up to 8 hours of controlled time) so in theory you could use 5 phases,
giving 5 x 8 which = 40 hrs of pause mode (which means only the timer is
operating, no power to elements or fan) then the 6

Turkey you may select to start the cooking cycle with convection at a higher
than normal cooking temperature to “adhere” the spices to the skin. Then you
may wish to allow the oven temperature to fall slowly so the second phase

combi cycle which then introduces steam into the oven chamber etc.

the 1
cooking phase would be set at 16 minutes and the second phase
would be a pause mode set at 2 minutes.
At the second phase the oven heating elements and fan turn off, as the fan
takes approx. 1

When the timer goes off and the audible alarm sounds indicating cycle has
ended, when the operator opens the oven door there is no rush of hot air
being blown out as the fan has already stopped.

ECO - Delta Cooking
®
It is a unique method of controlling the oven chamber temperature in
conjunction with the core temperature of the food. The operator is able
to select a “delta” value between 1 °C < 120 °C, we recommend using
between 20 °C < 70 °C
An example of Linear ECO - Delta Cooking
This type of cooking is ideally suited to large joints of meat and the way to
use it is to select the cooking mode, e.g. Combi. Then select a core
temperature value, then go into functions and select ECO - Delta. At this
point you will see on the oven temperature display “20 °C” which is a “delta”
value you may select. Using the dial knob select the “delta” value you wish,
for example 40 °C.
Close the oven door and press the start button to activate the cooking cycle
(if you wish you could also put in the second phase of a pause mode for
2 minutes, this would start when the core temperature you selected had been
reached).
The core temperature of the meat may be for example 14 °C when the
cooking cycle has started, the oven temperature will then go to approx. 54
°C, which is 40 °C above the core temperature. As the core temperature
of the meat rises by one degree so too does the oven temperature, with the
difference being maintained at 40 °C which is the “delta” value you selected.
If you selected a final core temperature of say 68 °C then the oven chamber
temperature would be 108 °C at the end of the cooking cycle.
This cooking method is much slower than the “normal” way of cooking but
the benefits are higher yields which translate to bigger profits!
Note For a more detailed explanation of ECO - Delta cooking refer
to page 36.

The air-o-steam® display always shows the:
“Selected Temperature” and the “Actual Temperature”
“Selected Time” and the “Time Remaining”
“Selected Core Temperature” and the “Actual Core Temperature”
This is to let the operator know (and supervisors) what has been selected for
various cooking cycles, should an operator select the wrong choice then it’s
easier for another person to see this and correct it.
During a cooking cycle, if the operator/supervisor sees that a wrong
temperature, time, cooking mode etc has been selected, to correct it they
simply press the correct button and hold for a few seconds which will then
prompt the display to “flash”.
At this point the correct input can be made then the oven will memorise this
and change the cycle accordingly, without having to stop and restart the cycle.
After 2 hours of steam operation, the air-o-steam

happen when the water temperature inside the boiler drops to 50 °C or below,
normally the next time the oven’s main power is turned on.
At the end of any of the 4 Cleaning cycles the oven will automatically go on
“stand-by” mode which turns power off to the steam generator elements,
shuts off the oven lights so the only energy consumption is on the led display.
This allows the operator to start a cleaning cycle then go home.

air-o-steam® Combi Oven
Has reached for the future with a precise control of both humidity
and air circulation within the cooking chamber
Even while cooking with Convection (Dry) forced air you can select a humidity
level for optimum results.
With a new airflow system and a larger oven cavity uneven cooking is a thing
of the past.
The following is a brief explanation of the various cooking modes available and
how to best use them for optimum results.
Humidity and Cooking
Having the option now to be able to select a “humidity” level while using
either the Combi or Convection cooking modes enables (with practice)
the Chef/operator to fine tune the cooking procedure to optimise results.
You must realise that food is a delicate product and ALL food consists
mostly of moisture, for example meats are at least 88% water,
vegetables even higher.
With the two different cooking modes you have two different humidity factors
to take into consideration, firstly with Convection cooking you are able
to select (by pressing the Convection mode button twice) a humidity level
you don’t wish to exceed. This humidity you will find present in the oven
chamber once the food starts heating up and cooking is coming ONLY
from the food itself.
This is very noticeable when cooking, for example, a full load of beef rissoles,
as with the amount of moisture coming out from the product you can get in
excess of 90% humidity, this then makes “browning” very difficult.
With the Electrolux patented Humidity control system you can select as
an example 30% humidity and when the ACTUAL humidity level approaches
30% the oven will automatically discharge humidity into the airspace above
the oven.
When cooking with the Combi cycle the humidity level is normally set
at 50%, this humidity is coming from the steam generator and introduced
to the cooking chamber via a vent pipe.
Now you have the possibility to also select a desired humidity level which will
be controlled by the oven through the patented Humidity control system
using a “lambda” sensor so when cooking for example ribs (mostly bone with
little meat) you need a higher humidity level than if you were cooking a large
roast beef. The reason is you must help the ribs retain as much moisture as
possible to get a nice juicy meat.

Dry Hot air cycle
With oven ventilation closed
With oven ventilation closed
With a maximum available temperature of 300 °C, this cycle is mainly used
for baking products such as bread, pastries, cakes, biscuits, pies, flans,
strudels etc.
Quick grilling of meats (steaks, cutlets, rissoles, burgers etc.)
As with all cooking modes it is very important to pre-heat the oven prior
to placing the food inside, generally pre-heat the oven to 30-50 °C abovethe
desired cooking temperature.
When grilling steaks at 250-270 °C pre-heat the air-o-steam
for at least 10 minutes first.
®
to 300 °C
This is activated by selecting open ventilation from the Advanced functions.
Again on this cycle a maximum temperature of 300 °C is attainable - for
a maximum time of 10 minutes.
This cycle is used for cooking for example puff pastry sheets for custard slice,
browning and crisping skin on poultry, pork etc.
Cooking full loads of meat rissoles, which as they heat up produce excessive
humidity levels, the open vent allows excessive humidity to escape.
25electrolux user guide
air-o-steam
®
Convection cooking
Cooking with the Electrolux patented air-o-clima Humidity level control
(activated by pressing the convection mode selection button twice)
This cycle lets you program a maximum humidity level to be obtained
within the cooking chamber. This is a necessity, as during cooking all types
of food when it starts heating up, moisture from within the food escapes
creating humidity inside the oven.
This is evident when opening the door and observing the steam rise into
the kitchen.
When cooking full load of, for example, chicken or meat rissoles, the amount
of humidity within the cooking chamber (vent closed) can reach in excess
of 95%!
Electrolux has overcome this problem thanks to its patented air-o-clima
humidity control system! Just select the humidity level you desire and leave
the rest up to the Electrolux air-o-steam

Combi Oven.
26electrolux user guide
air-o-steam

Combi Cooking mode
Combination of convection and steam cooking.
In this cooking mode the maximum attainable temperature is 250 °C
This cycle is best used for cooking all types of meat on the bone including
seafood and for the regeneration of pre-cooked foods.
When cooking meats (and remember the water content in most meats
exceeds 88%) the steam is assisting heat transfer into the food mass thus
accelerating the cooking process.
Steam is ideal for cooking these foods, but the maximum temperature being
only 100 °C it is impossible to obtain the desired browning (caused by the
caramelisation of meat juices).
With the Combination cooking mode a temperature of 250 °C can be
obtained, because the cavity is heated (either by electric elements or gas
heated tubes). It is therefore possible to obtain the desired browning effect.
Using the Electrolux patented air-o-clima humidity control system
The patented air-o-clima humidity control system is the only system that
determines the real humidity level inside the cavity of the oven, through direct
measurement using a Lambda sensor.
This system allows for real humidity control through injection of steam only
when necessary, and the aspiration into the cavity of dry air when humidity
level inside the cavity is in excess of the desired level for optimum cooking
results.
All you need to do is select the desired humidity level by twice pressing the
combi mode selection button, then using the main control dial to select
humidity %.
The air-o-clima will automatically keep the humidity, temperature and clima
inside the cavity at the ideal levels.

Steam cycle
Steam cycle-maximum temperature 100 °C
This cycle is used for a wide variety of cooking needs, most foods traditionally
boiled in a pot can be cooked on this cycle, the benefits include reduced
cooking times, better quality, retention of nutrients, vitamins, colour and most
importantly flavour.
Remember to use perforated cooking pans to allow the distribution of fan
forced steam around the product and not to overload the pans with food.
For optimum results 65 mm pans should be the deepest used.
Perforated pans also allow the condensation to escape so the product is not
sitting in water.

Super heated steam-maximum temperature 130 °C
To select “Super Heated Steam” press the steam button, now press the
temperature button and use main control dial to select a steaming temperature
between 101 °C up to 130 °C.
Low temperature steam cycle
With a temperature range from 25 to 100 °C, the Steam cooking mode is also
ideal for cooking delicate foods such as small fish fillets, scallops, scampi,
chicken breast, sausages, sous-vide, leafy vegetables, light egg custards etc.
Full or half Energy Power and/or Fan Speed
It is not always the case that the Chefs or operators are cooking large

quantities of food, thus when loading up to 40% of the ovens capacity you
have the option of selecting either half energy (power) and/or half fan speed to
reduce operating costs.
Another benefit is when cooking very delicate items such as soufflé or
meringues, you can select low fan speed to prevent “pulling” foods into the
direction of fan.

Super steam cycle
Super Steam is using the assistance of the air-o-steam® heating elements to
boost the chamber temperature (also possible in gas heated models) thus
speeding up the cooking process of more robust foods such as Potatoes,
Sweet Potatoes, Pumpkin, Rice, some meats etc.
Super Heated Steam is ideal for cooking frozen vegetables for example, as
the temperature recovery is much faster due to the assistance of the oven
heating system.
Note that this cycle should never be used for cooking green vegetables as
the high temperature will spoil the foods natural colour, texture and taste.

And there’s More!!!
Other options include the following
Sequential cooking
This is a method of using two or more styles of cooking for the same food
for example roast loin of pork:
The first step is to steam the pork as this keeps it moist and finally finishing
with a Combi cycle, then using a convection cycle with vent open to
crispen skin.
Cook step 1 (or phase 1)
After pre-heating the oven (on Combi cycle to 110 °C), place the pork which
has been put on a wire grid over a roasting pan into the oven.
Insert the core temperature probe, select steam cycle at 100 °C, select a core
temperature of 65 °C then go to cook step 2.
Cook step 2 (or phase 2)
Select Combi cycle with a humidity level of 40%, set oven temperature
at 190 °C with a core temperature set at 72 °C, then go to cook step 3.
Cook step 3 (or phase 3)
Select convection cycle with ventilation open and set oven temperature at
260 °C and core temperature at 76 °C, now press the start button to start
cooking cycle, commencing with cook step 1 and finishing with cook step 3.
Tip: Scoring the pork skin with a knife every 1 cm and rubbing it with salt over
the surface will assist in achieving crisp skin.

L.T.C. Low Temperature
Cooking in AOS
Low Temperature Cooking has been developed over a period of time with vast testing in our own laboratory and in
conjunction with the University of Udine Italy. Using this method guarantees optimum yields every time from all types
of meat that would be otherwise roasted in the “traditional” way.
Another factor determining yields is whether or not the meat has been “manipulated” meaning if it has been
“boned out” stuffed with a filling, rolled and tied as you would with a shoulder joint or loin for example.
If the meat being cooked is a single piece meaning a leg with bone in, prime beef rib on the bone then the yields
are higher due to the meat not being cut open to remove the bone which increases the surface area being
exposed to heat during cooking.
Another tip is NOT to use any salt on the meat prior to cooking as all this does is “draw out” water from the meat which
can result in up to an additional 7% weight loss !! and has NO effect on the meats taste.
Season the meat AFTER it has been cooked.
