Safety instructions
Improper installation, maintenance or clean-
ing or modifications to the appliance could
lead to injury or death of the operator and
damage to the appliance.
Read the operating handbook carefully
before using the appliance.
This is how the combi steamer
works
You can cook various foodstuffs in your
combi steamer. To do this, steam,
convection (hot air with distribution) and hot
steam (superheated steam) are used.
This means that your combi steamer can
provide virtually all methods of cooking
foodstuffs. The steamer allows you to
steam, blanch, poach, stew, boil, roast,
braise, bake, grill, gratinate, regenerate and
defrost food stuffs, as well as cook sous-
vide and at low temperatures. This makes
your combi steamer a universal appliance.
Place food in the combi steamer in
containers or on grills, select the cooking
programme, cooking time or core
temperature and start the appliance.
Usage in accordance with cond-
itions
CONVOTHERM Combi Steamers may
only be used for the cooking methods
listed above.
CONVOTHERM Combi Steamers are
intended for commercial use.
The ambient temperature must be
between 4°C and 35°C.
To avoid accidents and damage to the
combi steamer, the operator must
instruct employees on a regular basis.
The appliance may only be used by
trained employees.
In addition, regular safety training for
operating staff is of the greatest
importance.
The appliance should never
be operated in a toxic atmosphere or
one at risk of explosion
be initially started up or operated at a
temperature <lower than 4°C, including
after transport, or outside
be operated outside without rain
protection
be used to cook foodstuffs in a sealed
container (such as cans or jars) if these
are not suited to this purpose
be used to heat up flammable objects
such as oils, fats, cloths or similar items.
be used to heat up non-food items (exc-
ept suitable appliance accessories).
Risk of death
Risk of explosion if smell of gas is
present
disconnect from gas supply
immediately
ventilate the room thoroughly
avoid creation of sparks (i.e.
operating a switch or telephone or
touching electrical switching
elements) or naked flames
inform your gas supplier or the fire
brigade (external telephone).
Electric shock
Before opening the side wall and carrying
out repairs or maintenance (by qualified
electrician only) the combi steamer
should be de-energised by the customer.
Risk of injury
Installation
Avoid placing cooking appliances such
as chip pans, deep fat fryers etc. beside
the combi steamer. There is a risk to
the operator of severe burns if water is
sprayed on to hot fat.
A sufficient safe distance should be
kept between deep fat fryers or chip
pans and the appliance (operating
range of hand shower).

Safety instructions
Operating
Caution: steam!
To open the door of the oven,
proceed as follows. First turn the
handle to a horizontal position
(raised position). This interrupts the
cooking programme and stops the
motor. Wait a few seconds before
slowly opening the door. Otherwise,
escaping steam may cause
scalding, e.g. of the face and
hands.
Risk of scalds!
If cooking containers filled with
liquids or a foodstuff which is liquid
during cooking, only those shelf
levels may be used which are
visible from the outside. Please ob-
serve the additional instructions /
stickers on the appliance.
Kitchen logistics
Do not store or use flammable gases or
liquids near the appliance. These could
be ignited by the heat generated by the
appliance, endangering both people
and the product.
Appliance malfunction
If you notice scratches, nicks or
cracks on the inside panel of the
appliance door, it must be replaced
immediately. Otherwise, the glass
panel could shatter during cooking,
leading to cuts.
The combi steamer must only be
used with a functioning magnetic
door switch. If a malfunction arises,
contact customer service
immediately. Otherwise, during
automatic cleaning, chemicals
could be sprayed on to the eyes or
skin of the operator, causing
irritation.
Cleaning
Use of non-original CONVOTHERM
cleaning agents can cause a risk to
health in the form of irritation of the
lungs or skin.
Please observe the safety instructions
on the labels and/or safety data sheets
of the cleaner.
Potential damage to product or
building
Installation
An accessible multi-pin circuit
breaker with a contact opening of at
least 3mm should be installed in
series near the appliance and must
be capable of shutting down the
appliance when undertaking external
cleaning, repairs or installation work.
You will find more detailed
installation instructions in the
installation instructions. For the
connection value, voltage and fuse
rating, see the technical data or
circuit diagram in the connection
area of the combi steamer.
All appliance types
To ensure that your CONVOTHERM
Combi Steamer remains free of
malfunctions, it should be serviced
at least once a year by an
authorised service partner.
Clean the guide rails of the
disappearing door once per month
with a greased cloth. This will
ensure long service life.
Carry out regular checks (at least
once a year) to ensure that the screws
and hinges of the disappearing doors
are firmly in place.
When not using the appliance for
extended periods, shut off the
water stopcock and disconnect the
gas/electricity supply to the combi
steamer.
EN
82
Safety instructions
Gas appliances
The exhaust connection and its
cover (on the back on the left) can
generate high temperature levels
with gas appliances.
No flammable materials should be
brought into contact with the
appliances. This could cause a risk
of fire.
Do not block or obstruct the area
beneath the gas appliance with
objects of any kind.
Only use the gas combi steamer in
a draught-free environment.
Cleaning
For the purposes of cleaning, the
hand shower must only be used for
the oven chamber and not for the
outer casing. Do not spray the air
intake or outlet apertures of the
combi steamer.
Only undertake cleaning and
maintenance when the combi
steamer is cold.
Do not use the hand shower to
spray the hot oven chamber.
Allow the combi steamer to cool to
below 60°C in the oven chamber.
Regular cleaning of the combi
steamer after day-to-day use,
inside and out, will guarantee many
years of satisfaction from your
CONVOTHERM!
Only use original CONVOClean
new or CONVOClean forte cleaning
agents from CONVOTHERM and
CONVOCare nozzle cleaner (for
automatic cleaning). Never use
irritant, highly alkaline cleaners or
abrasive agents. Damage caused
as a result of improper cleaning will
invalidate any warranty claims.
Do not use high-pressure cleaners
or water jets to clean your
CONVOTHERM.
Do not treat the combi steamer with
acids or expose to acidic vapours,
since this may corrode stainless
steel.
De-scaling
(by trained service technicians only)
Never operate the combi steamer
when a decalcifier has been
applied. De-scaling should only be
carried out when the appliance is
cold.
Immediately remove any decalcifier
fluid which has leaked out with
plenty of water.
Observe from day to day
Gas appliances
If the appliance is installed beneath
a hood, this must be switched on
during cooking.
If the appliance is connected to an
extractor with a flow failsafe
mechanism, the extractor pipe must
be cleaned regularly (observe
regulations applicable in your
country).
The exhaust outlet and its cover (on
the back on the left) can generate high
temperature levels with gas
appliances. Exhaust gases and hot
sheet metal parts can cause burns.
EN
83
Safety instructions
Before switching on
Lock the suction plate into place
above and below. Never reach
behind the suction plate during
operation and never manually stop
the fans.
Lock the engaging frame or the
shelf rack correctly into place.
If the ambient temperature at the
installation site is below +4°C, the
area should be heated up to room
temperature before initial start-up of
the combi steamer.
After transporting the combi
steamer at outside temperatures
below -5°C, the safety temperature
limiter may be triggered. This
should be remedied by a qualified
electrician.
In the case of an “E...” error
message, refer to the chapter
“What to do if...”
Loading/removing dishes
Risk of burns!
Depending on the cooking
temperature selected, high
temperatures can occur
particularly on food containers,
grills, tray trolley and on the
inner side of the door.
We recommend that you wear
protective gloves.
During operation, the
temperature of the glass panel
in the door and the outer casing
can sporadically rise to above
60°C.
Risk of scalds!

Practical hints for cooking
Steaming
With the “Steam” programme, you can boil, steam, blanch, poach and preserve.
Steaming at 100°C
You will experience the following
benefits:
Your dishes will have a rich natural
colour, bite and intensive flavour
Steaming is particularly good for
preserving vitamins, minerals and
secondary plant substances such as
colour and fibre.
Flavours are not transferred if different
foods such as fish and vegetables are
steamed at the same time.
Few flavourings, fat or salt are
required.
You can work quickly since steam is
constantly available.
Please note:
Particularly suitable containers for
steaming are punched GN containers
up to 65 mm deep. These ensure short
cooking times and prevent food
underneath in the GN container from
becoming flattened.
Always break up lumps of ice in deep-
frozen food so that everything is
cooked through evenly.
When steaming different kinds of food
at the same time, observe the cooking
times of each individual food item.
When preserving, the cooking time
should be geared towards product
type, container size and
characteristics. Your CONVOTHERM
is suited to making semi-perishable
foods. Please observe the normal
processes for preserving.
Mr. C recommends:
After steaming, rinse vegetables with
the hand shower, season and butter.
To make vegetables in liquid, use the
stock. Steam the vegetables in
punched containers and simply allow
the stock to drain into unperforated
containers.
Long-grain rice should be steamed in
covered containers. To cook, use 1½
parts cold water or cold stock to one
part rice. Prepare the rice approx. 20 -
30 minutes before filling the oven.
Durum wheat pasta should be
steamed in covered containers. To
cook, use at least 5 parts cold water to
one part pasta.
Dumplings should be steamed on
greased metal baking sheets. Uncover
immediately after cooking. For
extended output times, keep hot in a
water and starch solution.
Potatoes should be sprinkled and
mixed with fine-grained salt directly
before steaming or soaked in salted
water for 15 minutes.
EN
89
Practical hints for cooking
Steaming at 30°C to 99°C
You will experience the following
benefits:
You can prepare foods whilst
preserving all their goodness.
Reduced loss of weight for meat and
sausage with optimum flavour, aroma
and colour.
Burst skins and meat contents are
avoided when boiling or heating up
sausage.
Optimum culinary results are achieved
for sensitive foodstuffs such as
terrines, galantines, flans, farce
dumplings, crème caramel and diet
dishes.
Well suited to the use of vacuum
cooking following the sous-vide
process.
When the oven temperature is set
below 100°C, the fan wheel starts up.
Temperatures which are precise to the
degree ensure optimum preservation
of proteins, i.e. they will not leak from
the food.
Please note:
Bear in mind that cooking times will be
longer when steaming at 30°C - 99°C
compared with steaming at 100°C.
Mr. C recommends:
Cook pastry products made of yeast or
bread dough or flaky pastry at a
temperature of 35°C.
The grains will swell gently for
wholefood dishes such as cereals.
Create trout en bleu by dousing the
trout in wine or vinegar.
Ham and sausage can be boiled.
Steaming at 101°C to 120°C
You will experience the following
benefits:
Steaming at temperatures above
100°C is mainly for sensitive foods
such as jacket potatoes, beetroot,
turnip, pulses and cabbage.
Compared with steaming at 100°C,
cooking times are reduced by around
10 %.
Please note:
When cooking small amounts of food,
select an oven temperature between
105°C and 110°C, or when the oven is
fully loaded, between 110°C and
120°C.
Mr. C recommends:
To gently regenerate food which has
already been divided into portions in GN
containers, use covered GN containers.
Caution:
Only insert containers within
the U-shaped bar. When
placing dishes on the runners,
containers may tip slantwise out of the
engaging frame or trolley.
EN
90
Practical hints for cooking
Superheated steam
Use the “Superheated steam” programme to roast large joints and bake.
You will experience the following
benefits:
Superheated steam guarantees
optimum cooking conditions every
time, i.e. the oven climate, geared
towards the specific product and
volume being cooked, sets itself
automatically through the CLOSED
SYSTEM.
Humidity values need not be set
manually.
Food will not dry out.
The flavour and aroma of dishes are
optimally preserved.
Foods can be cooked very rapidly with
minimum loss of weight.
Flavours are not transferred if different
foods are cooked at the same time.
Baked items such as yeast and bread
doughs and puff pastry rise perfectly.
The pores of large roasting items are
immediately closed by the steam,
making sautéing unnecessary.
It is not necessary to pre-steam roast
dishes separately, since the
CONVOTHERM will automatically
introduce steam at the start of the
cooking process.
If required, the interior of the oven can
be demoisturised (Crisp
&Tasty
function) to achieve juicy, crispy
products that are evenly browned all
over.
Please note:
Before baking, pre-heat the
CONVOTHERM at least
10-15 minutes in advance at 20-30°C
above the baking temperature.
Always pre-heat floor models with the
pre-heat bridge
For deep-frozen products, always pre-
heat for at least 15 minutes at 250°C.
The higher the oven temperature, the
more intensively is the food browned,
but also the greater the loss in weight.
Browning of food begins at a
temperature of around 120°C.
Generally speaking, the oven
temperature should be reduced by 10-
20% compared with traditional cooking
methods.
Mr. C recommends:
Place the roasting items on grills. This
will allow the pores of the meat to be
closed all the way round. You will
achieve even results without having to
turn the meat over.
Always place baking dishes or
casseroles on a grill. This will ensure
that food cooks more quickly and
evenly.
To create sauces or sauce bases,
place a tray beneath the grill where the
joints are cooking. To this you should

Practical hints for cooking
Convection
The “Convection” programme is suitable for all roasted, baked and grilled products as well as
for gratinating, all of which require no moisture.
Roasting and baking
You will experience the following
benefits:
Up to 95% less fat required when
compared with standard cooking
methods.
If necessary, the oven can be
demoisturised to create a crisp, crusty
dish which is evenly browned all over.
For baking, demoisturising
(Crisp
&Tasty function) will create a fine
crust.
Please note:
Pre-heat the CONVOTHERM for at
least 10-15 minutes prior to cooking at
a temperature of 20-30°C above the
cooking temperature.
Always pre-heat floor models with the
pre-heat bridge.
The higher the oven temperature, the
more intensively is the food browned,
but also the greater the loss in weight.
When roasting, the oven temperature
is reduced by 10-20% when compared
with traditional methods.
Mr. C recommends:
To create breaded dishes, it is best to use
convenience products and fats which are
suited to combi steamer.
Cooking at low temperatures
(LT cooking)
(oven temperatures from 30°C to 100°C)
Dark types of meat are particularly suited to
low-temperature cooking.
You will experience the following
benefits:
Joints are roasted so carefully that the
raw weight is retained almost in its
entirety.
To prevent the surface of foods from
drying out, the fan will start up at oven
temperatures below 100°C.
Low-temperature cooking can also be
used to prepare meals overnight.
The meat becomes very tender and
juicy.
Please note:
The oven temperature should be only
a few degrees higher than the final
core temperature.
The higher the oven temperature, the
higher the loss of meat.
This method of cooking creates no
crustiness.
Mr. C recommends:
You can keep prepared dishes warm for up
to two hours at an oven temperature of
80°C and with the fan operating, without the
surface drying out.
Caution:
Only insert containers within
the U-shaped bar. When
placing dishes on the runners,
containers may tip slantwise out of the
engaging frame or trolley.

Practical hints for cooking
Regeneration
This programme allows you to regenerate prepared dishes on plates or platters in a short space
of time.
You will experience the following
benefits:
When regenerating, you will always
have the optimum cooking conditions,
i.e. the oven climate, geared towards
the specific product and volume being
cooked, sets itself automatically
through the CLOSED SYSTEM.
You can create dishes at quiet times
when not busy and arrange them on
plates or platters.
Dishes do not require to be kept hot.
This means no loss of quality.
Ready-prepared dishes will not dry out
during regeneration.
Neither puddles of condensation nor
dry edges form on the plates.
For banquets, you can regenerate
however many plates you need on
demand.
The plated banquet trolley can be
easily loaded from any side.
Please note:
Always pre-heat the CONVOTHERM.
Always preheat floor models with the
pre-heat bridge.
You will find pre-heat temperatures as
well as regenerating times and
temperatures in the table (on the
following page).
After regenerating for the third time in
a fully-loaded oven, always pre-heat
again briefly, i.e. for a minute or two
(see table on following page).
After pre-heating, only open the doors
of the CONVOTHERM once the fan
has stopped and then load prepared
plates or platters quickly. This will keep
warm air inside the CONVOTHERM.
Large, compact foodstuffs such as
dumplings, roulades and casseroles
take longer to regenerate than items
such as meat slices, vegetable side
dishes, rice and quartered or diced
potatoes.
Foodstuffs should be distributed evenly
over the plate in small pieces. Avoid
overlapping large surfaces and
arranging food to different heights.
To achieve good quality, do not
interrupt the regeneration process.
After regenerating, pour sauces on to
plates with a sauce dispenser.
EN

Practical hints for cooking
Mr. C recommends:
Place fish and meat on a base so that
it is evenly regenerated and does not
stick to the plate.
Meat should be roasted until it is rare if
it is to be cooked to medium after
regenerating.
Vegetables, rice and pasta should be
buttered before regenerating.
Slice compact foods such as
dumplings or whole fillets.
When transporting some distance, use
a thermal cover. Before use, place the
thermal cover in the CONVOTHERM
to pre-warm it.
Caution: do not cover the air
outlets.
For large banquets, work with several
plated banquet trolleys. Thermal cover
will allow you to keep plates warm for
up 20 minutes. During this time, you
can regenerate other batches. This
ensures that dishes can be served to
your guests hot and all at the same
time.
Make up sauces which are to be
poured over slightly thicker, so that
they can absorb remaining moisture
from fish and vegetables.
Store optimised culinary ideas for
standard dishes as recipes. This will
guarantee smooth efficiency for
banquets or à la carte cooking.

temperatures when oven is fully loaded

When the pre-heat temperature is reached, you can start regenerating
again immediately.

Practical hints for cooking
Measuring the core temperature
Measuring the core temperature is recommended when cooking slow roasts and when
regenerating food in GN containers.
You will experience the following benefits:
Precise cooking can be achieved
regardless of the size and weight of
the joint. This guarantees you quality
results every time.
There is no need to spend time and energy
keeping an eye on and checking the degree
of cooking of slow roasts.
Meat loss is reduced by up to 50 %
compared with standard cooking
methods.
The multi-point sensor takes
measurements at several points along
the sensor tip and automatically
recognises the coolest core
temperature it detects as the centre of
the joint of meat. The multi-point
sensor prevents incorrect readings and
makes handling easier.
The CONVOTHERM PC-HACCP
software stores the core temperature
measurement for automatic compiling
and archiving of HACCP-related data.
You should therefore make use of this
software.
Use the multi-point sensor for
documentation purposes (possible
temperature range between -5°C and
150°C).

Please note:
The multi-point sensor should not be
used to remove food from the oven.
Before use, cool down the multi-point
sensor with the hand shower.
Insert the multi-point sensor through
the centre of the piece of meat.
When the buzzer sounds for the end of
cooking, slow roasts should be
removed immediately from the
CONVOTHERM. This will prevent
overcooking.
When selecting the final core
temperature, ensure that slow roasts
are able to recover by approx. 3°C
after being taken out of the
CONVOTHERM.
The core temperature you select is
highly dependent upon the dining
preferences of your guests and the
demands this places on your kitchen.
