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.
• Follow strictly the attention and warning label indications
on the appliances.
• Cleaning and maintenance may only be carried ou t when
the appliance is cold.
• In case a connection with a sealing is opened, always a
new sealing 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 up, 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
elements 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

3. 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
Measuring the temperature of the pan base
Precise measurement of the temperature of a pan base using
methods in which contact with the base takes place by touch-
ing it with a probe (thermocouple, thermometer, etc.) is very
unreliable and generally leads to deviations in the order of
minus 68°F (20°C) to 104°F (40°C). The use of heat-conduct-
ing paste does not result in any substantial improvements.
Correct results can be achieved by means of infrared meas-
urement using a pyrometer (e.g. Raytek's Raynger, series
ST2L). To prevent reflection from the pan base, a heat-resist-
ant, fibre-glass tape (e.g. Scotch Brand tape from 3M) must be
bonded to the area to be measured. A surface area of 2 x 2
inch) 5 x 5 cm is enough for this purpose.

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.

5.1 FU1. OPERATING FOIL
EXCHANGE
Removal
Operating foils (FO) are bonded to the sheetmetal 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 tom
and then lift up out of the fixa-
tion. 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 mountingh
Sidewall (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
underneath.
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. Please refer
to § FU1.6 for instructions.
Removing the Front pan
cover (VA):
The front panel of the pan
cover can be removed as fol-
lows without removing the
base (BD): remove the front
screws (SB), pull off the
panel underneath the pan,
draw the panel down and out
of the pan flange.
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. Suitable 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 6 - 8 inch (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 important to apply firm,
even pressure. The ideal working temperature
is approximately 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 applica-
tion, the foil has a working temperature range
from -40°F (-40°) to +248°F (+120°C) continu-
ous temperature load and 356°F (180°C)
short-time temperature load.
