SAFETY MEASURES
• Maintenance work, adjustments, conversions and repairs
may only be carried out by an authorized technician. These
technicians must be instructed by the manufacturer and
carry out the work in accordance with specific national and
local regulations. Parts requiring replacement are only to
be replaced by original spares.
• Strictly follow the attention and warning label indications on
the appliances.
• Cleaning and maintenance may only be carried out when
the appliance is cold.
• In case a connection with a seal is opened, always a new
seal should be used when installing the connection.
• The manager is responsible for ensuring that all compo-
nents relevant for safety (jacket safety valve, drain valve,
pressure gauge, thermostat, excess-temperature thermo-
stat) are in perfect working order at all times. The operating
condition of these components must be examined by an
authorized technician at least once a year and any defects
remedied if required.
• Before beginning any servicing, all appliances must be dis-
connected from the power supply; the steam, condensate,
hot water and drinking water pipes must also be turned off
or closed. Disconnection from the power supply is effected
by switching off at the main switch or removing the fuses
fitted to the power supply.
• The internal wiring in the appliance as well as the earth
connections must be carried out in accordance with the
complete electrical schematic. Basically, all metal parts on
which electrical connections are located must be earthed.
• Boiling pans of this design and operating function do not
require special acceptance tests. They are subjected to a
pressure and operating test which meets the regulations on
the manufacturer's premises. Recurrent pressure testing is
not compulsory. To ensure the complete operating effi-
ciency and safety of appliances, however, owners should
arrange for personnel authorized by the manufacturer to
check on all safety equipment and to conduct pressure
tests at regular intervals.
• After the appliance has been connected, the service agent
must carry out a test of all functions in the course of which
all the programs and operating states of all operating ele-
ments as laid down in the operating instructions are
checked.
• The conclusion of a maintenance agreement should be
recommended to the user.
MAINTENANCE INTERVAL
An obligatory service check is required annually.
1. CONSTRUCTION/ FUNCTIONS
The food is uniformly heated by steam by an external jacket.
The following sources of energy are used: electricity, saturated
steam and hot water. The pans are equipped with an elec-
tronic comfort control unit with regulation of the food tempera-
ture, with programming of the cooking time and with optional
programming of the starting time. The control system is oper-
ated via a membrane keyboard. The boiling pan has a varia-
ble-speed tilting facility powered by an electric motor. All
models can be optionally equipped with a mixer unit, stirring
and cooling system.
2. TECHNICAL DATA
Tilting boiling pan with jacket heating system.
Electrically heated tilting boiling pans models have water-filled
jackets. Max. working conditions in the jacket: pressure 0.8 bar
(5.8 psi), temperature 244°F (118°C).
Heating-up time: time taken to heat the pan 100% full of water
from 68°F (20°C) to 194°F (90°C). The heating-up times of the
appliances heated with steam or hot water change in line with
the data of the source of energy.

4. MAINTENANCE CHECK LIST
S = Part is relevant for safety
If, during servicing, an increased number of failures is noted
for a part that is relevant for safety, a written report must be
sent to the „Aftersales“office responsible without delay
Check Fault B Remedy
Connections for protective
conductors
Connections for equipoten-
tiality
Check that all electric con-
nections and contacts to
terminals, coils, switches
and junctions are tight.
In case of loose contacts
B tighten contacts.
Check contactors and
relays.
The contacts must move
freely without sticking or
jamming. Check all contac-
tors for traces of burning.
In case of defects or faults B
replace contactor or relay.
Measure the individual
phase currents with a
clamp-on ampere-meter on
the power supply immedi-
ately before the connection
terminals with the appli-
ance switched on full and
compare the currents with
the data on the electrical
schematic.
Identify defective consumers
(heating systems) by care-
fully measuring the individ-
ual currents. If major
deviations are discovered
B Replace.
Inspect internal wiring. In case of defect cables
B replace cables.
Check condition of all oper-
ating foils.
Defective foils
B replace.
Optical inspection of the
whole control unit.
S If faults are discovered
B repair faulty units or
exchange parts.
Test all operating functions
and check that the control
unit works correctly.
S If problems are encountered
B find reason and repair fail-
ure.
Check switches for easy
movement and correct func-
tion.
If the switch is hard to turn or
makes a noise
B replace.
Compare the food tempera-
ture display with the actual
value.
If the deviation is
1°
B Adjust the display again.
Inspect fixation and condi-
tion of all temperature sen-
sors (jacket, food,
deaeration, excess temper-
ature) and check electrical
connections.
S If sensors, fixation, electrical
connections are found to be
faulty
B replace the parts con-
cerned.
Test if all heating elements
work well by measuring the
indicated heating-up time or
measure the current.
If larger differences are noted
B exchange the faulty heat-
ing element.
Check all elements of the
display on the operating
panel with service test 1.
If any element of the display
fails
B exchange the whole oper-
ating board.
Inspect fixation and condi-
tion of all switches (power
isolator, control, tilting, stir-
rer) and check electrical
connections.
If defects to any fixation or
electrical connections are
discovered
B replace the parts con-
cerned.
Check function of acoustic
signals.
If the sound is off key or no
sound is heard
B exchange the whole con-
trol board.
Check the number of deaer-
ations and thus the water
level in the jacket with
parameter PNo. 1.6.5.
If the number of deaerations
is very high or there is too lit-
tle water in the jacket
B refill with demineralized
water and reset the value of
PNo. 1.6.5. to 0.
Check max. jacket pres-
sure (except on pans with
direct steam heating).
If it deviates from the max.
reference value
B reset the max. value with
PNo. 1.0.3.
Carry out a leak test of the
jacket (except on pans with
direct steam heating).
If there is a leak and high
water loss
B locate the leak and seal.
Check function of deaera-
tion valve.
If it is not tight during opera-
tion
B clean or replace the valve.
Check function of aeration
valve (only direct steam
heated pans).
If it is not tight during opera-
tion
B clean or replace the valve.
Inspect safety valve for cor-
rosion, damage and leak-
age. Make function test and
maintenance.
S Clean the valve. If any inad-
missible properties are
encountered
B replace the whole valve.
Check the lid for correct
shape or damage.
If irreparably damaged
B replace the lid.
Check the lid hinges for cor-
rect function.
If defective
B disassemble, clean,
grease, adjust the hinge.
Inspect pipe work and
screw connections (pans
with external heating) for
tight sealing.
In case of leakage
B replace seals or pipes.
Check function of mixing

6.1 OPERATING FOIL
EXCHANGE
Removal
Operating foils (FO) are bonded to the sheet metal surfaces
(cover plates) with self-adhesive coatings. They are removed
with a spatula, a screwdriver or a knife.
Remove the connecting rail
(VS)Loosen the front nuts M6
from underneath. Bend the rail
up slightly at the front. Pull the
rail out of the appliance.
Switch panel (F) removal:
Unscrew the two screws at
location (1) underneath the
switch panel and the nuts (MH)
at location (2) on the top, pull
out the switch panel at the bot-
tom and then lift up and out of
the fixation. The panel is
turned up 90° like a door and
hung at the top on the console.
Cover (A) removal:
If there is a connecting rail
installed to the cover it has to
be removed first. (see 5.3.1.).
Remove the nuts (MU) (two on
a single console, four on a twin
console) at the relevant loca-
tion (2). Lift the cover at the
front and pull it out of its clip
attachment at the back (3). If a
mixing unit is fitted, this does
not need to be removed from
the cover.
Service panel (V) removal:
Remove the two external nuts
(6) at the front and pull the
panel from its rear attachment
points (5).
Floor mounting on plinth
Side wall (S) removal:
To remove this, the switch
panel (F) must be removed
first. Remove the nuts (4) and
(5) inside. The upper internal
wall (W) cannot be disassem-
bled. It must be removed and
refitted together with the pan.
The panels are refitted in the
reverse order to that described
above.
Cover (A). The height of the
cover can be levelled by fitting
more or fewer shims (BE) and
tightening the nuts (MH).
Hanging the operating panel
(F) on the console
Removing the pan base (BD).
Set the pan in the horizontal
position. Remove the screws
(SB) from underneath and take
out the base (BD) from under-
neath.
Fitting the base (BD).
Carefully clean any remains of
the old seal from the edge of
the base. Stick a new sealing
strip (DB) on the edge of the
base. Carefully position the
threaded clip (SM) on the
jacket (MK). Tighten the
screws (SB).
Pan jacket. The pan jacket is
not removed during normal
servicing work.
Cleaning
The surfaces to which the foil is to be
applied must be clean and dry, i.e., free
from dust, grease, rust, paint, etc. Suita-
ble for cleaning: toluol or 3M article S-
152 stick remover.
Procedure: shake the can thoroughly and
spray evenly on the surface to be
cleaned. (Distance about 5.9 - 7.9“ / 15 -
20 cm.) Rub over with a clean lint-free
cloth. If surfaces are heavily soiled,
repeat the process.
Sticking on the foil
Remove the protective backing, taking
care not to touch the adhesive. After
positioning press down well. It is impor-
tant to apply firm, even pressure. The
ideal working temperature is approxi-
mately 77°F (25°C). Temperatures below
50°F (10°C) should be avoided since the
adhesive becomes too hard and instanta-
neous adhesion is reduced. Following
application, the foil has a working tem-
perature range from -40 to +248°F (-40°
to + 120°C) continuous temperature load
and 356°F (180°C) short-time tempera-
ture load.

6.2 UNIVERSAL CONTROL
The appliances are equipped with a precise state-of-the-art
electronic microprocessor control system with digital preselec-
tion of temperature, cooking time and starting time. The control
system can also be remotely controlled using a PC. For con-
trol-system operation, please refer to the Operating Instruc-
tions.
Temperature setting
If the nominal temperature set on the display (AT) is below the
boiling point of water 207 - 212°F (97 - 100°C), this tempera-
ture will be reached during heating up and then maintained at
this value by the electronic control system and the careful sup-
ply of energy. The nominal temperature will not be exceeded
during this process.
When cooking certain products with poor heat conductivity
such as sugar solutions, nominal temperature settings
between 212 and 230°F (100° and 110°C) are required in
order to reach boiling point. The correct setting is largely a
matter of experience.
Power setting
Fixed power settings can also be preselected with the elec-
tronic controller. In such cases, the preselected power is given
after boiling point has been reached. Setting the controller to a
fixed setting is done in order to be able to enter the degree of
boiling in the food individually, i.e. according to the food, the
amount of food, the position of the lid, etc. The following fixed
power settings can be set using the display (AT):
Setting Power Operation of 4 heating elements E
(AT) (%
L1 6.25 (E1/7.5 sec. on/22.5 sec. off)
L2 12.5 (E1/15 sec. on /15 sec. off)
L3 25 E1
L4 37.5 E1 + (E2/15 sec. on /15 sec. off)
L5 50 E1 + E2
L6 62.5 E1 + E2 + (E3/15 sec. on /15 sec. off)
L7 75 E1 + E2 + E3
L8 87.5 E1 + E2 + E3 + (E4/15 sec. on /15 sec. off)
L9 100 E1 + E2 + E3 + E4 ( ) = intermittent operation
In the case of directly steam-heated and indirectly steam
heated pans, the percentile opening time of the valve for the
supply of energy corresponds to the above-listed power val-
ues. In the case of electrically heated pans, the 4 heating sys-
tems and contactors are used cyclically, i.e. the order E1 - E4
is changed after each use in order to ensure that wear of the
heating and the contactors is distributed evenly.

6.2.1 PARAMETER PROGRAMMING
General remarks
The same software is used for all appliances which are
equipped with this control system. To ensure that each appli-
ance operates as desired, specific parameters must be
entered. The control systems which are installed in the appli-
ances at the factory or are in stock, are equipped with the
microprocessors fitted including the software. The software
contains a default setting (GS) of the parameters (PNo.). The
default setting is selected in such a way that a minimum of
parameters have to be adjusted for the individual setting of the
different appliances. In principle, the corresponding parame-
ters have to be entered for each appliance.
Software version
The microprocessor (MP) bears an adhesive label stating the
software version and the date. Any change in the software
usually also involves a change in the parameters. Please
always ensure that the version of the parameter list used
matches the software version. The following general rule
applies: if the software version has a different number, the
parameter list with the same version must also be used. If the
software version has a different additional letter in the version
number (e.g. version 2.51A, version 2.51B, etc.), the parame-
ter list does not change. Only the number of the version with-
out the additional letter is important for the parameter list.
Microprocessor (MP)
2 IC insertion sockets are located on the control board. The
large insertion socket for 64 pins accepts the microprocessor.
The software program is located in the ROM (Read Only Mem-
ory) of the microprocessor chip. An OTP version (One Time
Programmable) microprocessor is used. This version can only
be written to once and cannot be erased. This means that any
program change also means the use of a new chip. The old
chip can no longer be used.

EEPROM (EP)
The small insertion socket for 8 pins is for the EEPROM (Elec-
trically Erasable Programmable Read Only Memory). The
parameters are stored in this IC. Once stored, the parameters
remain in this IC even when disconnected from the power sup-
ply until they are changed by reprogramming or erased.
Before the parameters are changed for the first time to suit an
appliance, the values for the default setting must be loaded
into the EEPROM. The parameters can be entered in 2 differ-
ent ways:
Manual input (the more frequent case) and PC input.
6.2.2 MANUAL PARAMETER INPUT
Default setting (GS) of the parameters
The default setting of the parameters is the same for all appli-
ances which are equipped with this control system. Dependent
on the type of appliance, more or fewer parameters are
required with values that differ from each other to some
degree.
3 of the 4 buttons on the membrane keyboard (Q, R, V and P)
are used for the programming of parameters. The 3 buttons
are located in the bottom row on the operating panel. Buttons
V and P are located under the membrane and are not visibly
marked.
)
(*) Display (AT): After "def" is displayed for approx. 2 seconds,
the actual value of the current food temperature will appear.
Display (AZ): Clock time appears (only with process com-
fort control).
The control system program now contains all the default set-
tings for the software version of the microprocessor installed.
Important
If the default setting (GS) of the parameters of an appliance
which was already in operation is programmed for new, all
parameters which register running times are set to zero.
Parameter-setting (X) specific to each appliance
In order to change the numbers (PNo.) and the content (X) of
the parameters, the same buttons are used as those for enter-
ing the default setting.)
Display (AT): Parameter PNo... 1 appears
Display (AZ): None
The parameter numbers (PNo.) and the values (X) which devi-
ate from the standard setting can now be entered alternately
on the display (AT).
As the same display is used to show the numbers (PNo.) and
the content (X) of the parameters, the following difference is
made between the two figures:

Rate of change of the displays
Increases (button P) or reductions (button Q) can be done at
three different speeds:
• Press the button briefly changes in single steps
• Press the button longer
• at least 1 second the display changes slowly
• press for at least 5 seconds the display changes fast
End of parameter programming
If the content (X) of a parameter (PNo.) is changed, the
changed value is stored when the display (AT) is changed
from parameter content to parameter number using the button
R. The following applies for the last parameter content
changed or if only a parameter content has been changed.
Parameter programming can be finished in 2 ways dependent
on whether the changed value is to be stored or not.:
6.2.3 PROGRAMMING SPECIFIC APPLIANCE AND
USER DATA
Appliance-specific parameters are only set on the basis of the
type of appliance. User-specific parameters are dependent on
user order, user requirements, siting terms and are only appli-
ance-dependent to a certain degree.
The parameters are programmed at the factory to the default
setting (GS) if no specific information is given.
New appliance installation
In the case of new appliances, the control system is pro-
grammed at the factory to the appliance-specific setting.
When the appliance is installed at its intended site, the fitter in
charge of installation must set or check the following parame-
ters on the control system. The parameter values are different
for each software version.
