Working safely with your oven
1.1 Certifications
CE conformity
The Leventi ovens comply with the CE-norm. This can be
checked by means of the conformity declaration as
printed in the user manual.
1.2 Maintenance
Maintenance and repairs to the ovens must be always
carried out by recognised specialists. Never remove side
panels components and other parts but always have your
service done by a qualified and recognised Leventi
service firm.
There are specific instructions for the installation of the
oven in the technical instruction manual. These
instructions are familiar to Leventi approved technicians.
A shortened version is included in this instruction
manual.
When carrying out repairs always us the original and by
Leventi provided spare parts. Should this not happen,
then there is chance on unnecessary damage to
equipment.
The activities such as described in the chapter
maintenance can be carried out by the end-user.
However, the oven should always be disconnected from
the power supply and it should have cooled down
sufficiently before you start with the small maintenance.
Incorrect installation, maintenance and repair can result
in consequential damage. Leventi is not responsible for
this damage if the conditions in this manual are not
observed.
1.3 Intended use
This oven has only been intended for activities and food
product preparations as defined in this guide. The use of
the oven for any other aim is not been permitted.
1.4 Removal of baking trays with products
When you remove a baking tray from the oven, it can tilt
due to the weight of the products. This can lead to hot
products, or the baking tray itself, falling onto you.
Consider your own safety and hold the tray securely
1.5 High Voltage
The oven works on an electrical current of
380/415 or 220/240 Volts, depending on of
the model. When you open the side panels for
maintenance or cleaning then always pull out the plug
from the partition socket. That prevents accidents. The
most critical places have been marked with the indicated
sticker.
Check the power cables regularly. This cable should
never be damaged, nor conducted under the furnace and
should not cross a warm surface or should be led over
sharp edges.
When the cable and/or the plug is damaged, don’t use
the oven but firstly repair the faulty component by an
acknowledged electro technologist. The plug socket
must easily reachable so that in need the plug can be
disconnected from the power supply fast and easily.
Never put the oven in front of the socket but always
besides the socket.
Never plunge or bring the plug or socket into contact with
water or any other fluid. When this should happen then
short circuiting results are possible.
Twinge the plug in the wall socket entirely to prevent
overheating and catching fire of the connection plug and
the socket.
Never pull the plug from the socket by pulling at the cable.
The connection between the plug and the cable can be
damaged as a result.
1.6 High temperatures
When you do maintenance on your oven, let it
cool down sufficiently first. The heating element
can reach a contact temperature of 550°C and
heats all components to high temperatures. Contact of
these hot components can cause burns. The most
critical places have been marked with the indicated
sticker.
You find this sticker among other things on the inner
window and on the front list at opened door. When you
open the oven door, steam can come out the oven
chamber. This steam will come outside and can be very
hot. This also possible when at closed door no steam in
the oven is visible. Leventi recommends oven mitts when
placing or removing objects from the oven. This prevents
burns. You can order oven mitts at Leventi.
1.7 Working with Booster equipment
The Booster oven (with microwave-function) is equipped
with several safety features which prevent the continued
operation of the oven when the door is open.
7
Working safely with your oven
If you make use of the booster function, only do so when
there are products in the oven chamber. With an empty
oven, radiation may leak outside or the oven may suffer
technical damage. Although the amount of this radiation
falls well within international safety standards, we advise
against such use.
Do not make use of the booster function when making or
amending your own cleaning programme.
The inside of the door is equipped with a serrated metal
edge covered with foil. This edge ensures the closing of
the door. Take care that this metal edge does not bend!
1.7.1 Booster safety instructions.
The Booster function is not intended to be used
independently but always supports the normal
preparation process. Do not use the Booster just to
warm a cup of water etc.
Do not use the oven if the door or door rubber is broken.
Allow this to be repaired by an authorised person.
Do not heat liquids and foodstuffs in sealed containers.
This creates the risk of explosion.
Use of the booster for the heating of drinks can lead to
delayed heating in which cooking can continue to occur
(even if the programme has finished). Beware of this
when removing drinks.
Liquids and drinks may not be heated in closed or sealed
containers. This prevents products from exploding.
Heating with microwaves can lead to irregular heating.
Always stir products such as drinks and baby food well
and afterwards check the temperature carefully. This
prevents the risk of burns.
When heating packaged products in the oven using the
microwave function look into the oven regularly. This is to
check for the occurrence of flames.
Boiled eggs and eggs in shells may not be heated using
the microwave function. These products explode. They
can still explode even once the heating programme has
finished.
1.8 What to do in case of...
Fire
Bring yourself and others to safety. Call the fire
department. If you think you are able to fight the fire
yourself then shut off the oven immediately, disconnect it
from the power supply. When an extractor hood has
been installed or connected then shut these off
immediately.
Water nuisance
Water nuisance can arise by leakage or flood. Switch of
the oven from its power source and close the water
supply. Call the Customer Services Department for
recommendations.
Power failure
When the power shortly falls away then the motor
security of an electric oven can become effective. This
prevents damage of the motor. The thermal protection
must then be reset. The settings of the oven do not
change by a discontinuance of the power supply.
8
Working safely with your oven
WARNING: Use of the booster for the
heating of drinks can lead to delayed
heating in which cooking can continue to occur
(even if the programme has finished). Beware
of this when removing drinks.
WARNING: Do not heat liquids and
foodstuffs in sealed containers. This
prevents exploding products.
WARNING: Heating with microwaves can
lead to irregular heating. Always stir
products such as drinks and baby food well and
afterwards check the temperature carefully.
This prevents the risk of burns.
For Boosteroven only: Make a copy of this page, cut out the warnings and hang
it next to the oven in order to alert the user to the
dangers of unsuitable operation.

2.6 Brief explanation food preparing
2.6.1 Mastermind
In the menus you can choose the various preparation
methods. Below you will find a short explanation hereof.
For a more detailed description of the preparation
methods and preparation tips please go to page 17.
Always bear in mind the following table when setting the
oven.
Preheat
The preheat phase will bring the oven to the right
temperature before the products are being loaded into
the oven. By using this phase it is possible to achieve a
higher temperature then necessary for the preparation,
this will compensate for the loss of temperature whilst
loading the oven.
The preheat phase will end when the set temperature
has been reached.
Moist phase / Steam phase
This phase is mainly used for preparing Bake-Off
products. With this phase you can set a certain amount
of moist (in ml) before you start the actual bake. Besides
that you can also add Boost, when you have an oven
equipped with Leventi’s Advanced Booster Technology.
You can end this phase with a pause time.
This phase has ended when the set amount of moist has
been injected and the pause time has elapsed.
Preparation based on time
Standard preparation method based on a specific time.
With a humidity level of 0% you can open or close the
valve. With all levels above 0% the valve will stay
automatically closed.
When you set the humidity level at 100% and
temperatures of 100°C or lower, special cooking
techniques are started.
This phase has ended when the set time has elapsed.
You may also use the Booster function of the Combimat
Mastermind Booster³ to support and speed up this
preparation method.
Preparation on core temperature
A standard preparation method where the core
temperature of a product is of importance.
With a humidity level of 0% you can open or close the
valve. With all levels above 0% the valve will stay
automatically closed.
When you set the humidity level at 100% and
temperatures of 100°C or lower, special cooking
techniques are started.
This phase has ended when the set core temperature
has been reached.
You may also use the Booster function of the Combimat
Mastermind Booster³ to support and speed up this
preparation method.
Preparation on Delta-T
This preparation is used when the core temperature of
the product is of importance. The room temperature is,
however, maximally Delta-T (Delta stands for difference,
T stands for temperature) higher than the core
temperature. This will enable a slow increase of the
temperature of the core of the product.
This phase has ended when the set core temperature
has been reached.
You may also use the Booster function of the Combimat
Mastermind Booster³ to support and speed up this
preparation method.
Regeneration
Preparation method mainly used for regenerating
prepared dishes. By using a special moist control there
is no dehydration and loss of taste.
This phase has ended when the set time has elapsed.
You may also use the Booster function of the Combimat
Mastermind Booster³ to support and speed up this
preparation method.
Preparation on Cook & Hold
Preparation method where the core temperature of the
product is of importance. The difference between the
room temperature and the core temperature will be
slowly decreased to the level of the set value. This will
enable a slow increase of the temperature of the
product.
Important: after reaching the set core temperature the
oven will retain the core temperature at the set value.
This phase will only end when you end the preparation.
This phase you can only use when this is the last or only
phase of the programme.

3.1 Switching on
Switch the oven on by using the main switch.
The main switch can be found on the bottom right hand
side of the oven.
The display will now show a clock.
To actually start working with the oven you should press
the I-button (below) on the operation panel.
Important: When you have an oven equipped with a boiler
then the boiler may be rinsed. This can take several
minutes and is necessary for a good operation of your
oven. The rinsing will be indicated in the display with the
needed time. After the rinsing you can start working with
the oven.
When the previous session with the oven has been
ended in the cleaning cycle by switching the oven off, then

Preparation methods Combimat
8 Preparation methods Combimat
8.1 Various preparation techniques
The basic techniques for the preparation of food in the
oven are:
Convection
Convection is the preparation of products in hot dry air.
This means a humidity level of 0%.
Steaming
When products are prepared in dry, very moist air this is
called steaming. This means a humidity level of 100%.
Combisteaming
When products are prepared in dry, moist are then this
is called combisteaming. This means a humidity level
from 10 to 90%.
Booster function
The booster function supports the stated preparation
method and can speed up the process by the addition of
energy via microwave radiation.
Always bear in mind the following table when setting the
oven.
8.2 Preparing food in the oven
Regeneration (Mastermind)
Regeneration is the process of reheating products with
the aid of, convection/steam/ combisteam. The steam
percentage can be set in such a way that products can
be rethermalised without dehydrating.
Cook&Hold (Mastermind)
When using
Cook&Hold the
core temperature
of the product is of
importance. See
figure 1.
The oven will be
preheated after
the start up
(dotted line A) to
the set room-
temperature (C).
In the mean time the core temperature (line B) is being
measured. When that starts to rise (the product is
getting warmer), the oven chamber temperature will be
slowly led down. After a while the core temperature will
reached the desired and set value (point D). From that
moment on the temperature in the oven chamber will be
kept constant. This process doen’t end.
Delta T
When using Delta T the core temperature of the product
is of importance. The oven temperature will be held at a
user set temperature difference (delta T) above the core
temperature. If the core temperature rises 1°C, the oven
room temperature will rise the same value.
This process ends when the the core temperature
reaches the set value.
Core temperature
Also with the preparation with the core probe the core
temperature of the product is of importance. The
product will be heated until the desired/set value has
been reached. At that momen the oven will stop and will
confirm that the product is ready in the display.
When your oven is not equipped with a core probe
sensor then you can also use this method with a
separate core temperature probe, however you should
set the temperature of the oven chamber yourself.
Baking
Meat and fish that require a short preparation time and
an intensive coloring of the skin can best be baked at
180-250 °Celcius.
Operation:
Cover the products that you want to bake with browning
butter and add herbs. Cream butter for the taste is best
to be used after the preparation process.
You can simultanuously brown on both sides when you
use special silicone mats, then you donít need to turn the
product during the bake. The breaking of flat fishes will
also belong to the past this way, as the mats are flexible.
Also the most patisserie products can be baked best

Preparation methods Combimat
with convection heat.
Grilling
The combimat is perfectly suitable to grill products. This
is mostly done at convection (however preparation on
combisteam may result in even better end results).
Combigrilling.
This preparation technique is the most valuable power in
your kitchen. Combigrilling uses steam and convection at
the same time. Both techniques stimulate eachoter.
Stoving
Stoving is possible in one continuous operation in the
Leventi Combimat. You enable steam and convection.
You only have to add the sauce afterwards.
Cooking, steaming, and poaching
The steam boiler or the direct injection system of the
Leventi Combimat will supply you with sufficient steam for
steaming or poaching of products.
By also enable convection during cooking and steaming
much time can be gained. By enabeling convection the
oven will be drier, please keep this in mind.
When you cook or steam a lot (eg. Vegetables and
noodles) then a boiler equipped machine will be
preferable choice. This means a humidity level of 100%
and a temperature of 100 °Celcius or lower.
Grilling
In the Leventi Combimat you can grill perfectly. You place
the products on grills. You set the oven on convection,
between 230 and 250° Celcius. The optimalised air
circulation in the oven chamber will grill the product on all
sides.
To enhance the grill effect, you should preheat the oven
and the grills at 250° Celcius. The grills will give the
products the remarkable brown stripes.
Gratinate
Gratinating is giving the finishing color of the products.
This is done by using convection.
By high temperatures you can add steam to keep the
product more moist. An example of this is gratinating
mashed potatoes.

Maintenance and cleaning
9 Maintenance and cleaning
This chapter is divided into Safety Indications, Cleaning
and Small Maintenance.
9.1 Safety instructions
Maintenance and repairs on the ovens should always be
done by recognised specialists. Therefore never remove
side panels, parts and or other items, but always use a
recognised service firm.
The technical manual contains installation instructions
which must be strictly adhered to.
When carrying out repairs only the original Leventi parts
should be used. When this does not happen then there is
a chance of unneccesary damage to your equipment.
The activities such as described in the chapter
Maintenance may be carried out by the user. However
the oven should in this case always be taken of the power
supply, and should have cooled down sufficiently.
For more safety information see the Chapter Working
safely with your Quadro.
Read the indications on the packaging and on the
security sheets that have been delivered with your oven
and the cleaning agents you use.
Ignoring the conditions in this manual can lead to serious
damage. Leventi is not responsible for this damage if the
conditions in this manual are not observed.
9.2 Cleaning

NEVER use abrasive materials or sponges or brushes to
clean the oven. This results in irreparable damage to the
oven.
After the preparation of products containing (high
amounts of) salt, such as fish and seafood, the oven must
be cleaned or thoroughly rinsed. This prevents deposits
and corrosion from the chloride elements in these
products.
Option handshower
Leventi can deliver the oven with an optional handshower.
When you use a handshower you will always have a water
supply at hand that you can easily use to clean or rinse
the oven chamber with. Ask your dealer for more
information about the Leventi handshowers.
There are various configurations with or without Fat
Separator, Soap Pump or Circulation Pump. This has
consequences for the operation of the operation of the
system.
Therefore follow the instructions in the display of the
oven accurately.
The total cleaning process will last about 1.5 hours. The
water consumption is about 20-25 liters of water and
80-400ml of cleaning detergent and 30ml of polishing
detergent. All depending on factors such as
waterpressure and the chosen intensity.

The stand and the trolley should be cleaned every week
by using a detergent and hot water.
Cleaning the extractor hood
The extractor hood should be cleaned every week by
using a detergent and hot water. Do not forget to also
clean the grid of the extractor hood.
Cleaning additionals
Aluminium baking trays should be cleaned with hot water
and detegent only. Important: NEVER use Ovenrein on
aluminium parts (baking trays, frying trays etc.) Should
you do this regardlessly then these parts may rust.
Grills and innerracks can be cleaned with Ovenrein. Then
they should be rinsed thoroughly with hot water. Place
grills and innerracks in the oven during the cleaning
process. This will save you time!
Silicone mats should be cleaned with a plastic dough
scratcher, every now and then you can also clean them
with hot water and detergent. Always rinse them off with
hot water! Be carefull to never fold, incise or cut silicone
mats!
Cleaning the drain grating
The drain grating on the bottom of the oven can be simply
removed by turning it, then you can simply clean it with
hot water and detergent. NEVER remove this part during
the cleaning of your oven, this to prevent that your drain
will be clogged by dirty water or large residue.
Cleaning drain
It is recommended to directly flush the drain with
abundant hot water after the preparation of products
that contain a lot of fat. You may add Leventi Ovenrein to
the water which gives a cleaning effect.
When the oven has already cooled down, then the fat in
the drain may have already coagulated. Then it will not
possible any more to remove this fat with hot water.
Important: with this treatment the water in the drain may
be hot (85° Celcius)!
Then you need to unscrew the backside of the drain
system on the oven and clean it from there.

Maintenance and cleaning
Time saving: when you clean the oven on a regular and
daily basis, then it will never get too dirty and the cleaning
process can be done in a jiffy.
9.2.7 Manually descaling the oven chamber
This chapter is mainly of use when you have an oven that
is equipped with a direct injection system. With these
ovens there may be a calcium residue (white) on your
oven chamber depending on the degree of your water.
This can be removed as follows:
Clean the oven as described in this manual.
Let the oven cool down to maximally 60° Celcius
Let the oven steam for 15 minutes at 60° Celcius
Then spray the oven chamber abundantly with Leventi
Ontkalker (decalcifier) and leave this for about 20
minutes to work.
TAKE CARE: ensure that you do not spray the door
sealing with de-scaler! This greatly prolongs the life of the
door sealing.
Then let the oven steam for 30 minutes at 100° Celcius
Clean the oven after the cleaning program by using a
handshower and or a moist cloth in order not to leave any
chemical residue behind. Also clean the door rubber!
9.3 Maintenance of the boiler
This chapter is only applicable when your oven has been
equipped with a boiler.
Flushing the boiler
The boiler will be automatically flushed when the oven is
turned on. The computer will decide itself if this is
necessary. The flushing cycle will only take a couple of
minutes. When the oven is too hot then it needs to cool
(the boiler) down first.
9.3.1 Decalcifying the boiler
Depending on the use and the degree of your water the
boiler needs to be decalcified. On average this needs to
be done once every two weeks (with a maximal water
degree of 3°dh). The oven will indicate when this needs to
be done.
The Mastermind will show the message that the boiler
needs to be decalcified.
The Digital showa the code B1
You decide when you want to decalcify the boiler
(preferably at the end of the working day in respect to the
time this process takes). But you should decalcify as soon
as possible.
Also applicable here: when you regularly decalcify your
oven then this will never happen as a surprise during
busy opening hours.
Starting up decalsifying of the boiler
With the Mastermind:
choose menu / cleaning / decalcify boiler
With the Digital:
Press simultaneously both and
as indicated in the figure for 3 seconds
The oven will start up the decacifying programme.
The boiler will be flushed after a cooling down period.
The masterfy will notify this, the Digital shows the code
B1-4.
Then follow the instructions in the display. The oven will
ask you to insert the decalcifier in the boiler.
The Digital shows the code B2-4.
Poor the indicated amount of Leventi Ontkalker in the
opening on the right hand side of the oven. Use a funnel
to poor in the decalcifier.
Then press continue.
The Mastermind notifies that the process is running, the
Digital will show the code B3-4.
The decalcifying process takes approximately eight
hours. It is recommended to plan this in at the end of the
27
Maintenance and cleaning
day. You do not need to stay with the oven during this
process. You can easily go home.
When the decalcifying is ready, then all functions are
switched off.
The mastermind display will be empty.
The digital will show B4-4.
You can switch on the oven again by pressing the I-0
button on the display. When the decalcifying process has
been started, the whole programme needs to be followed
to the end.
9.4 Maintenance water softener
Leventi advises to always apply a water softener. This will
prolong the lifespan of your oven (and particularly the
boiler versions).
When you have connected your oven to a water softener,
then on average this should be descaled at least every
two weeks to ensure a proper working. Therefore follow
the operation manual of your water softener.
Flushing the manual water softener
Below text is a short manual for the manual water
softener.
Important: NEVER remove the resin grains in your water
softener!
During the rinsing process
there is no water
connection to the
connected machine.
Keep this in mind.
Hang the end of the hose E
in a bucket.
Hang the end of the hose F
in a drain.
Turn the taps C and D (in
the direction of the arrows).
There will be water
pressure on hose E (max 2
liters).
Open the lid G
Fill the water softener with
one to one and a half kilos of
salt.
Close the lid G
Turn the tap C back (left,
according to the arrow).
There will be salt water
coming out of hose F
Wait for 2 hours.
Turn tap D back (left,
according to arrow).
The water softener is ready
for use.
Salt type: the salt will be used during the rinsing process
to clean the water softener. The salt should never be
present during normal use. Therefore use the two hour
period (50 liters of flushing water). After the rinsing
period the water coming out of hose F SHOULD be sweet
tasting.
9.5 Small maintenance.
9.5.1 Change the filter of the air cooler
The filter is located
at the shaft under
the operation panel.
This shaft contains a
filter for cooling the
air in the technical
area of the oven.
This filter should be
cleaned regularly. Check this filter at least every two
weeks.

Maintenance and cleaning
9.5.3 Changing the door seals
A door seal will ensure a good closure between the door
seal and the oven cavity. The door seal is subject to wear
and tear. When you replace the seal then act as follows.
Advise: poke a couple of holes in the rubber (in the back
that you use to put into the oven). This prevents the
sticking of the door seal.
• Remove the old door seal.
• Make the dent where the door seal fits in clean of
dust and any other residue such as kit.
• Then you apply a small quantity of kit in the lower
corners. Small tubes are available under article code:
05001086000.
• Start in the left upper corner. Press the corner.
Stretch the rubber out to the right above corner and
also press this.
• Then press the rubber in the two upper corners.
• Also stretch the rubber out to the left below corner
and also press this.
• Continue this operation until it fits everywhere.
• Then also press the doorseal firmly with a hard but
blunt object.
9.5.4 Reset after a power failure
You should never do this yourself. Let a specialised
service technician do this. In the switch board there are
many buttons and other parts which are under high
voltage. Wrong actions may lead to life threatening
situations.
