4.3 Operating and cooking modes
4.3.1 Operating modes
Manual cooking
In the Manual cooking mode, individual cooking programs and
equipment functions can be activated directly. The various cooking
modes and equipment functions can be modified individually.
Automatic cooking
In the Automatic cooking mode, saved cooking programs can be
activated and modified if necessary.
4.3.2 Types of cooking
Steaming
Steaming is a cooking mode, in which the food to be cooked is
cooked gently by means of steam in a temperature range of 30 °C to
130 °C.
Combisteaming
Combisteaming is a cooking mode, in which large roasts, casseroles
and baked goods can be cooked in a temperature range of 30 °C to
250 °C.
10014471-0ABBE-A
Hot air
Hot air is a cooking mode, in which the food to be cooked is cooked
without additional moisture in a temperature range of 30 °C to 250 °C.
17Operating instructions
Description of the unit
Regeneration
Regeneration is a cooking mode, in which the food being cooked can
be kept warm and prepared in a temperature range of 30 °C to 155
°C.
4.3.3 Expanded cooking functions
Expanded cooking functions can be used to modify individual cooking
steps for the particular food being cooked.
The following expanded cooking functions are available:
Manual humidification Manual humidification allows the cooking zone humidity to be
increased during operation.
Start time delay
When using the start time delay, temperatures that promote the
growth of harmful microorganisms on the food being cooked can
occur in the cooking zone. Observe food processing regulations.
The start time delay can be used to set a waiting period until the
program starts.
In this way, bottlenecks in production and preparation can be
avoided.
The prepared food to be cooked can be loaded into the unit and the
desired cooking program selected.
Heat (Ready2Cook)
The function can be selected when starting the cooking
program.
For many cooking programs such as baking, for instance, the correct
starting temperature is important.
The expanded heating function can be used to warm the cooking
zone to the correct starting temperature.
4.3.4 Core temperature measurement
When using core temperature measurement, the temperature inside
the food being cooked is measured by means of a core temperature
sensor.
As soon as the target core temperature is reached, the cooking
process is ended automatically or, in the case of a multi-step cooking
program, the next cooking step starts.
The use of core temperature measurement offers the following
benefits:
•Reduced energy and water consumption
•No overcooking
•Less weight lost by the food being cooked
•High HACCP safety

5.1 Operating the unit in an environmentally responsible manner
If used correctly, this Combisteamer achieves very low energy
consumption.
You can assist low energy consumption by:
•Avoiding continuous operation - the Combisteamer heats up very
quickly, which means that continuous operation is not necessary.
•Loading the cooking zone as full as possible - if practical, use a
Combisteamer with a smaller cooking zone.

WARNING
Risk of injury from a bursting core temperature sensor
•The core temperature sensor can burst as the result of
overheating of the measuring tip.
•Never heat a core temperature sensor with a cigarette lighter
or other heat source.
Measuring the core temperature is recommended for all types of
cooking to achieve an optimal result.
The unit has a core temperature sensor in the cooking zone and
can be equipped with an optional connection for an external
core temperature sensor.

The use of unsuitable cleaning agents often causes damage to
units. MKN makes great efforts to be able to offer a cleaning
agent, which on the one hand achieves an outstanding cleaning
performance, but which on the other hand does not attack and
damage the hot air steamer. We therefore recommend that only
our cleaning agent is used. MKN does not assume any
responsibility or liability for damage, which is caused by
unsuitable cleaning agents. Claims against MKN that are due to
this can not be upheld, not even within the scope of the
guarantee or warranty.
It is not permitted to cool the temperature sensor down in order
to start the cleaning procedure more quickly. The whole cooking
zone must be cooled down to 60 °C for effective cleaning.
Depending on the cleaning level selected, the fan may come to
a standstill for up to 60 minutes. This is not a cancellation of
cleaning but part of the cleaning program.
Automatic forced rinse is triggered in the following situations.
•Cleaning is cancelled manually. Cancelling within the first 10
minutes of cleaning does not trigger an automatic forced
rinse.
•Cleaning is cancelled automatically in the event of a fault.
•The Combisteamer is switched off and then back on during
cleaning. The automatic forced rinse begins when the unit is
switched back on.
If the automatic forced rinse is cancelled, it starts again from the
beginning.
It is not possible to start a cooking program, before the forced
rinse is ended.
