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

unit for function. Check for

leaks of water connections.

If the tap drips or if any pipes

leak

B replace seals.

Check the function of the

heating resistance.

If it is not warm

B replace it.

Run the stirring unit

(optional) in all programs

and check for irregularities.

In case of abnormal noise

B find reason. If necessary,

replace bearings, absorbers

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.
