be followed
CAUTION!
The kettle must not be left unattended when in use.
CAUTION!
The kettle must be operated from the front.
CAUTION!
Should a hazardous situation occur at the appliance, turn off the safety switch immediately.
CAUTION!
If error code E99 is shown, the pressure in the kettle is too high and the heating power supply to
the kettle must be turned off immediately. Disconnect the power supply at the main switch imme-
diately and make sure that the kettle is repaired before taken into use again.
CAUTION!
If a dangerous situation should arise involving the kettle, press the emergency stop button im-
mediately. This will stop all functions. The power is applied again by manually turning the emer-
gency stop button.
(This only applies to kettles with a stirrer)
CAUTION!
Always ensure kettle is sufficiently clean before use.
CAUTION!
Never touch the top or inside of the kettle without first checking whether it is hot, as a kettle that
is in use can become so hot that anyone touching it risks a burn injury.
CAUTION!
A kettle which has been in use will cool down very slowly and anyone touching it risks a burn
injury long after it has been switched off. The control panel does not give any warning of this.
CAUTION!
Be careful when the contents of the kettle are boiling. Splashes from the kettle and over boiling
liquids may burn or scald anyone nearby.
CAUTION!
Do not use abrasive tool of metal for stirring.

CAUTION!
Valves on the kettle bowl must not be opened, when the kettle is pressurized.
CAUTION!
For safety reasons, the kettle must not be filled to within 5 cm from the rim. Otherwise, there is
an increased risk of over boiling and emptying the kettle will be difficult.
CAUTION!
During use, no steam may be discharged from the safety valve. If this happens, disconnect the
power supply at the main switch immediately and make sure that the kettle is repaired before tak-
en into use again.
CAUTION!
During normal use, hot air/steam will be discharged from the venting valve. In the event of a fault,
steam may be discharged from the safety valve.
Note that any steam that is discharged could cause burn injuries.
CAUTION!
Connections between the steam jacket and the outside must not be blocked. This applies, for ex-
ample, to the safety valve, venting valve, vacuum valve and level valves.
CAUTION!
It is forbidden to stay behind the kettle, when it is in use.
CAUTION!
The kettle must not be moved when its contents are so hot that there is a risk of scalding.
CAUTION!
If a dangerous situation should arise involving the kettle, press the emergency stop button im-
mediately. This will stop all functions. The power is applied again by manually turning the emer-
gency stop button.
(This only applies to kettles with a stirrer)
CAUTION!
Stainless steel surfaces are protected by a thin layer of chromoxide, which is vulnerable to dam-
age by use of steel implements and exposure to chlorine, as found in normal kitchen salt for ex-
ample.
Never add salt to cold water in a kettle. Wait until the water is hot, when the salt will dissolve. This
will prevent salt crystals settling at the bottom of the kettle where they can damage the chromox-
ide layer, exposing the steel to corrosion.
CAUTION!
If the kettle is on castors, the castor brakes must be engaged when the kettle is in use.

Adjusting the heat
NOTICE!
When the kettle is heating, pressure is built up inside the jacket. This pressure can be observed
at the pressure gauge at the rear of the kettle.
Automatic water level control in steam generator
Water level in the steam generator is monitored by the kettle control system. Water will be added auto-
matically if necessary to maintain the correct level.
Manual draining of condensate
Steam-heated kettles only
Under normal operating conditions, condensate is bled off automatically.
Under certain conditions or as a result of incorrect installation, condensate can build up in the bottom of
the kettle.
This causes a loud noise when steam is passed through the condensat.
In such instances, the condensate can be drained through a valve at the bottom of the kettle jacket.
Fig. 0-12 Valve for condensate out
CAUTION!
Beware of hot steam/water when valve is opened!

we know what‘s cooking
NOTICE!
The heating power function is used to determine the temperature of the steam jacket based on
the food temperature, and therefore how powerful the heating should be.
As the food is heated, the temperature of the jacket will automatically increase.
Lower power gives gentler heating but a longer heating time.
Higher power gives less gentle heating but a shorter heating time.
When power step 9 is selected, the temperature of the jacket will be set to maximum and the heat-
ing time will be the shortest possible.
General
The heating power supply is switched on/off by pressing . The LED will illuminate when the heating
is switched on.
To ensure that the food is heated uniformly and quickly, it should be stirred whenever possible. This also
gives an even distribution of heat, and therefore better temperature measurement to control the heating
process.
The kettle must be in the vertical position in order to heat its contents. If this is not the case, error code
U10 will be shown and the LED will flash until the kettle has returned to the vertical position or the heating
has been switched off. If the kettle is vertical again within two minutes, the heating will be switched on
automatically. If it takes longer than this, the heating must be switched on manually.

Chilling
AutoTemp 36 and 56
CAUTION!
Watch out for discharging water/steam from the bottom of the kettle when the chilling function
is activated.
The chilling function is used to chill the contents of the kettle.
In technical terms, there are two solutions:
• Tap water is let in through the steam jacket from where it flows to the floor grate.
• Chilled water is pumped from an ice bank / chilled water tank through the steam jacket and back to
the ice bank.
In both cases, the steam jacket is filled with water until the temperature of the jacket is decreases to
80ºC, before the chilling process is started. This ensures that there is no pressure in the kettle when the
chilling process is started.
Chilling mode
The kettle’s function depends on whether it is in heating mode or chilling mode. The control panel indi-
cates which mode is active.
Fig. 0-15 Key and LED for chilling
1 LED for heating mode
2 LED for chilling mode
The kettle is switched to chilling mode by pressing and holding the key down for three seconds until
the LED for heating mode extinguishes and the LED for chilling mode illuminates. If the user attempts to
switch to chilling mode and chilling mode has not been activated in the factory settings menu, error code
U40 will be shown.
NOTICE!
When chilling, depending on the contents of the kettle and stirring there may be a difference be-
tween the temperature shown in the display and the actual temperature of the food.
It is therefore important to check the temperature of the food with another temperature measure-
ment directly in the food.
Setting the set point for food temperature
With the AutoTemp 36 controller, the user cannot set the set point for food temperature, only start and
stop the chilling process.
With the AutoTemp 56 controller, both the set point for food temperature and the required chilling inten-
sity can be set.
The set point for food temperature is set by pressing so that the display flashes. Set the temperature
set point using the arrow keys.The function will be exited automatically after three seconds without a key
press or if another function is selected.

18/69
Document 10000028013-DOC-000-00-EN
we know what‘s cooking
NOTICE!
To ensure that the food is at the temperature set point, it may be necessary to set the set point
for food temperature lower, e.g. to 1 ºC.
Starting and stopping chilling
Chilling is started/stopped by pressing .The LED will illuminate when chilling is switched on.
The kettle must be in the vertical position in order to chill. If this is not the case, error code U11 will be
shown and the LED will flash until the kettle has returned to the vertical position or chilling has been
switched off. If the kettle is returned to vertical position within two minutes, chilling will be switched on
automatically again. If it takes longer than this, chilling must be switched on manually again.
NOTICE!
The kettle’s chilling function works best when the contents of the kettle are stirred during chill-
ing. This ensures uniformly distribution of cooling throughout the food.
Setting water consumption for chilling AutoTemp 56
This function is used to set the intensity of the chilling. The lower the value that is selected, the smaller
the quantity of water that passes through the steam jacket and the longer the chilling process will last.
When power step 9 is selected, the flow rate will be set to maximum and the chilling time will be the short-
est possible.
The required chilling power is set by pressing so that the display flashes. Set the required power using
the arrow keys.The function will be exited automatically after three seconds without a key press or if an-
other function is selected.
Setting water consumption for chilling AutoTemp 36
The required chilling power is set in the user menu point 5.1.
NOTICE!
By this feature, when using open cooling, water consumption can be significantly reduced.
Heating mode
The kettle is switched to heating mode by pressing and holding the key down for three seconds until
the LED for chilling mode extinguish.
The kettle now performs an initialisation which takes several minutes, as the steam jacket must be emp-
tied of water. During this period, the LED next to flashes and the kettle can neither heat nor chill.
When the initialisation is complete and the kettle is ready to heat, the LED next to will illuminate.
AutoTemp 16 and 32
The chilling function is used to chill the contents of the kettle. Chilling takes place by letting water through
the steam jacket down to the floor grate.
NOTICE!
The kettle’s chilling function works best when the contents of the kettle are stirred during chill-
ing. This ensures uniformly distribution of cooling throughout the food.
