The oven must be supplied with softened drinking water with a hardness value of 0.5 to 5°F
(It is obligatory to use water softener to reduce the formation of scaling inside the boiler). The
water pressure must be in the range of 150 to 250 kPa (1.5 – 2.5 bar). If the water pressure
exceeds 2.5 bar, install a pressure reducer device upstream. If the pressure is below 1.5 bar, use
a pressure pump to increase the level.

The connection to the water supply is done using the ¾” threaded solenoid valve on the
back (at the bottom) of the appliance (see fig. 1), fitting a mechanical filter with a cut-off cock
(before connecting the filter, allow a certain amount of water to flow out in order to remove
any waste from the pipe).

There is a drainage pipe on the back of the appliance (see Fig. 1) for emptying the cooking
chamber. A pipe of at least 30 mm internal diameter (DN30) must be connected to this pipe
that is resistant to the steam temperature. To avoid throttling, we advise using a rigid pipe
without any elbow bends along its length. The pipe must have a constant inclination of at least
5% along its length (the length is that from the outlet pipe from the appliance to the drain and
must not exceed 1 meter overall). The outlet pipe must flow into an open drain on the floor
(Fig. 2). If not, there must be a difference in height between the outlet pipe on the appliance
and the drain of at least 30 cm (see Fig. 3) to ensure the water flows out correctly. In conformity
with hygiene regulations in force, the pipe connected to the water outlet pipe on the appliance
must not be directly in contact with the outlet point.

- When using the oven for the first time, we advise you to run it load-free at maximum
temperature for about one hour. In this way, any unpleasant smells, due to thermal
insulation, and grease residue from assembly are eliminated.

- This appliance must be exclusively used for the purposes for which it was expressly
designed, i.e. cooking foods in the oven, any other use is improper.

- The oven can be used for all oven cooking of pastry, bakery and gastronomy products,
fresh and frozen, for re-conditioning refrigerated and deep frozen foods, for steam
cooking meat, fish and vegetables.

- When placing food in the cooking chamber, allow a space of at least 40 mm between
pans to avoid over-obstructing the airflow.

- Do not use pans with edges higher than necessary: the edges act like barriers preventing
circulation of hot air.

- Pre-heat the oven before each time it is used to guarantee the best performance.

- For the cooking to be as even as possible, place the food evenly in each pan, considering
the size of the pieces, layers or the thickness.

- Do not salt the food when it is in the cooking chamber.

- To check the cooking cycle is proceeding correctly use the internal light in the chamber
do not open the door if it is not necessary, to avoid wasting energy and prolonging
cooking times.

First ignition

The oven can be used for the first time only after the chamber has been carefully cleaned
with a special detergent for stainless steel. The detergent must not contain acid substances
(chloride acid, bleach, etc.) or be abrasive. Alternatively the chamber can be washed with warm
soapy water or warm water and a drop of vinegar. Rinse well and dry with a soft cloth.

First ignition (without food inside the oven) serves to eliminate any unpleasant smells (which
are quite normal) due to the thermal insulation heating up that covers the cooking chamber and
any oil residues from assembly of the metal parts.

After turning the power on (close the unipolar switch fitted upstream from the appliance)
and the water (open the cut-off cock), proceed as follows (see the figure of the control panel):

- press the on/off push button;

- set the time (knob “1”) at one hour (shown on the time display);

- set a temperature (knob “2”) of 270°C for the cooking chamber (shown on the
temperature display);

- check the door is closed;

- press the start/stop push button: the cooking chamber starts heating up.

When the time is up, the oven turns off automatically and the beeper sounds for 10 seconds.

Cooking techniques

There are three different cooking techniques with this oven which can be used singularly,

one after the other or combined.

3.5.1

3.5.1 3.5.1

3.5.1 Steam cooking (moist heat)

Steam cooking (moist heat)Steam cooking (moist heat)

Steam cooking (moist heat)

The boiler produces live hygienic steam which enters the cooking chamber without being

pressurised, where the fans make it circulate very fast.

The climate regulation system which allows dividing the steam production, in percentage,
should be set at 100%, while the cooking chamber temperature can be set between 50°C and
130°C.

Steam cooking is indicated where a boiled effect is required, and it has the advantage of
leaving the nutritional content of the food unaltered (the vitamins and flavour of the food are
conserved), the outer appearance (the colour is conserved, no lumps or air bubbles are formed
and the surface does not break up) and the weight is conserved, as no liquids are lost from the
food during cooking.

3.5.2

3.5.2 3.5.2

3.5.2 Convection cooking (dry heat)

Convection cooking (dry heat)Convection cooking (dry heat)

Convection cooking (dry heat)

The heating elements heat the dry air inside the cooking chamber. This heated air is evenly
distributed by the high speed of the fans. This gives an even temperature throughout the
cooking chamber and even cooking even when the oven is full.

This means that different types of food can be cooked on the various shelves (as long as they
need the same cooking temperature) without flavours and smells being mixed together.

The cooking chamber temperature can be set between 50°C and 270°C.

Besides evenly browning the food without having to turn it, convection cooking can be used
to cook au gratin and is particularly convenient for rapid defreezing, for sterilising preserves and
drying mushrooms and fruit.

3.5.3

3.5.3 3.5.3

3.5.3 Convection + steam cooking (dry heat + moist heat)

Convection + steam cooking (dry heat + moist heat)Convection + steam cooking (dry heat + moist heat)

Convection + steam cooking (dry heat + moist heat)

This type of cooking exploits the combination of dry and moist heat. The heat is dosed by the
climate regulation system which can divide, in percentage, the production of steam and the
production of dry heat (drying the cooking chamber), optimising the cooking climate for each
dish.
The cooking chamber temperature can be set between 50°C and 270°C.
The fact of using a hot-moist climate inside the cooking chamber with variable temperature and
moisture levels, is the most convenient and efficient way of cooking: cooking times are reduced,
the surface of the foods remains soft and does not form a crust, there is little weight loss and
the fatty mass is reduced.

The special hot-moist climate at low temperatures is ideal for re-conditioning food.

3.6.1 3.6.1

3.6.1 Core temperature cooking technique

Core temperature cooking techniqueCore temperature cooking technique

Core temperature cooking technique

The temperature can be set inside the core of the food to be cooked, using the special
needle core probe that is supplied with the oven. The probe must be pushed into the centre of
the food in the thickest part, avoiding the bones. Place the food inside the cooking chamber
and pull out the thermal probe lead and close the oven door. The probe plug must be plugged

into the special socket (see Fig. 1) at the bottom of the control panel. Press the push button

to select the core cooking temperature (led alight on ) between 0°C and 100°C using knob
no. “2”, the temperature is shown on the temperature display.

When a cooking cycle is started with a core probe stage included (the time display shows the
wording “Prob”), when the set temperature is reached inside the food the cooking cycle passes
onto the next stage no matter what time has been set. If the core probe is activated within any
of the four stages, with the other three deactivated, the cooking cycle finishes automatically
when the set temperature inside the food is reached, no matter what time has been set.

Cooking with the core probe can be graduated over the four stages (for very delicate
cooking) and, for each stage, the temperature and the climate inside the cooking chamber can
be set besides the temperature inside the food.

As the thermal probe is a needle which can easily be removed or broken, we advise setting
the cooking time for the stage that it is used in.

If the probe is connected and operating, the stage finishes when the set temperature is
reached; otherwise, if the probe is not connected or is broken, the stage finishes at the set time.

If the probe is not connected or is broken, when the cooking cycle starts the beeper sounds
intermittently for 10 seconds, the time display shows the flashing message “Prob” and the

previously set temperature disappears from the temperature display (

---- ---- ---- ).

The core temperature of the food can also be measured (when no temperature has been set):
it is sufficient to slide the needle probe into the food.

_ TECNOEKA Srl __________________________________________________________ use and instruction manual _

_ page 20 _________________________________________________________________________________________

In this case, when the cooking cycle has been started, when the push button is pressed
the temperature is selected automatically (shown on the temperature display) that is measured
by the probe (led alight next to ).

Warning

WarningWarning

Warning: Before removing the food from the oven after cooking with the core needle probe.

Carefully remove the hot probe from the cooked food, taking care not to leave it
hanging out of the cooking chamber as it could cause burns.
We advise leaving it to cool down before using it again – to avoid damaging pricks in
the food.
To prevent any irreparable damage to the thermal piercing probe (core probe) do not
use it in high temperature cooking ABOVE 230°C, and ensure that the probe lead is
not touching any hot metal surfaces inside the oven.

T) functionT) function

T) function

This function allows keeping the difference (∆T) between the temperature inside the food
(measured by the needle probe) and the temperature in the cooking chamber constant. This
means that the temperature in the cooking chamber is the sum of the temperature inside the

food and a fixed “∆T” temperature that is set by the user (see the graph).

The Delta-T temperature is the difference between the
temperature inside the food and the temperature in the
cooking chamber

In practical terms, there is a gradual increase of the temperature in the cooking chamber,
with a constant difference with respect to the temperature inside the food which, thanks to this
constant difference, is cooked slowly and gently (in meat the proteins are protected, as no
surface tension is caused by the rapid formation of the crust).

After selecting the temperature inside the food (core temperature) and setting the level (knob

“2”) press the push button again to select the “∆T” function (the led next to the ∆∆∆∆T

lights up) and to set the temperature (knob “2”) (on the basis of our experience this
temperature should be between 30°C and 70°C).

When the “∆T” function is used for cooking, the method for using the needle probe is the

same as that described in paragraph 3.6.1.

If grease remover detergents are used to clean the stainless steel, ensure they do not contain
corrosive acids (no sort of chlorine, even if it is diluted) or abrasive products. Follow the
indications given on the product and the warnings about its use, wearing rubber gloves during
cleaning.

Do not use iron pads, steel wool or scrapers as they would ruin the surfaces.

Do not leave food on the steel surfaces for a long time that contain acid substances (lemon
juice, vinegar, salt, etc.) as they could cause corrosion.

Ordinary cleaning of the boiler

Each time the oven is turned on, the water in the boiler is emptied and a washing and rinsing
cycle beings. During this phase, the oven can be used normally, there could just be a slight delay
in producing the steam, should it be needed for the cooking stage. The water is emptied from
the boiler (at regular intervals) even when the oven is working.

4.3 Extraordinary cleaning (decalcification) for the boiler

Extraordinary cleaning (decalcification) for the boilerExtraordinary cleaning (decalcification) for the boiler

Extraordinary cleaning (decalcification) for the boiler

The innovative design of the boiler (with the heating element on the outside and not
immersed in the water), the washing and rinsing cycle that is systematically repeated each time
the oven is turned on and the fact that softened water is used (hardness between 0.5°F and
5°F) all aid in drastically slowing down the formation of lime scale inside.

However, to get the best performance from the boiler, we recommend decalcification at least
every 6 months (for ease, this can be done at the end of the working day).

Proceed as follows (Fig. 4):

- Turn the oven OFF (green led alight) and let it cool down;

- unscrew the threaded plug “A” on the top of the oven, taking care the seal “B” does
not fall;

- use a funnel to pour the descaling liquid into the hole (an amount of 500 ml = 0.5 litres
is sufficient), avoiding pouring it over the steel surface (vinegar for food use is ideal – it
does not contain any corrosive substances for stainless steel, it is an effective limescale
remover and is compatible with food use);

- screw the threaded plug firmly in place so that the seal guarantees it is perfectly
watertight;

- leave the limescale remover liquid to work for at least 8-9 hours (or overnight);

- press the push button and keep it pressed until the confirmation beep is heard (the
green led lights up to confirm the function has been activated).

An automatic procedure will empty the limescale remover from the boiler and will begin a
washing cycle that lasts for about 5 minutes. The green led goes off on the push button when
the cycle is finished.

The oven is now ready for use.

Cleaning the cooking chamberCleaning the cooking chamber

Cleaning the cooking chamber

For hygienic reasons, it is good practice to clean the cooking chamber at the end of each
cooking cycle, otherwise it should be cleaned at least once at the end of each day’s use.

For easier cleaning, remove the side grills by unscrewing the 4 fixing screws (hold the reeded
nut between your thumb and forefinger and turn it in an anti-clockwise direction) remove the
drainage plug on the bottom and proceed as follows:

- spray a special degreasing product for stainless steel on the external walls, on the fan
casing (do not spray it through the fan grids) and on the glass inside the door;

- leave the product to work for approximately 20 minutes with the door closed;

- turn the oven on to 70-80°C;

- run a cycle with maximum steam (100%) for around 15 minutes;

- when the cycle is complete turn the oven off, leave the cooking chamber to cool down
and rinse well;

- Dry with a soft cloth or run a heating cycle, with the temperature at 150-160°C for
about 10 minutes (the cycle can be repeated if necessary).

The side grills and drainage plug must be cleaned separately and then replaced.
When cleaning is terminated, leave the oven door slightly ajar.

Cleaning the door seal

For hygiene and good operations, it is good practice to clean the door seal at the end of each
day’s work. It should be carefully washed with warm soapy water, rinsed and dried with a soft
cloth. Any incrustations or food deposits must be carefully removed, without using sharp metal
tools which could irreparably damage the seal.

4.7 Cleaning the door

Cleaning the doorCleaning the door

Cleaning the door

The glass on the door inside the cooking chamber can be cleaned with the same degreaser as
used for cleaning the chamber or a normal glass cleaning product can be used (non toxic).
Normal glass cleaning products can also be used to clean the glass on the outside of the door,
or simply warm soapy water, rinse and then dry the glass well with a soft cloth.

If dull marks form between the two door glasses, these can be removed by dismantling the
internal glass.

To do this, unscrew the 4 fixing screws on the glass (hold the reeded nut between your
thumb and forefinger and turn it in an anti-clockwise direction), taking care not to drop the 4
plastic washers which protect the glass from direct contact with the metal part of the screws.

To make dismantling of the internal glass easier, first unscrew the two screws that fix the
glass to the bottom of the door, as this way the glass is suspended. We advise performing this
operation with the aid of a second person (one person holds the glass while the other can
unscrew the screws in perfect safety). After eliminating the dirt between the two glasses,
replace the internal glass following this procedure in reverse.

Cleaning the external casing

The external steel surfaces should be cleaned with a cloth soaked in warm soapy water or
with a drop of vinegar added, they should be rinsed well and dried with a soft cloth.

If you use specific cleaning products, they must correspond to the requirements for cleaning
given in the paragraph “General information” (paragraph 4.1).

You should also remember that the table the appliance stands on or the surrounding floor
should not be cleaned using corrosive acid products (for example muriatic acid), as the fumes
that are given off could attack and damage the external steel casing.

Periods without use

If the appliance is not used for a long time, it is good practice to unplug it from the mains (at
the magnetothermal safety switch upstream from the appliance) and to turn off the water with
the cut-of cock on the main supply line. It should be carefully cleaned inside the cooking
chamber and outside, taking special care to remove any salt deposits which would cause
corrosion to the steel surfaces.

We also advise protecting the appliance with an oily base spray (e.g. Vaseline oil), which
forms an effective protective film on the surface of the steel.

A suitable covering would also protect the appliance from the dust.
