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 thermo­stat) 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 effi­ciency 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

The food is heated by the thick base of the pan under which several electric rod heaters are located. The pans are equipped with an electronic comfort control unit with regulation of the bottom resp. food temperature with or without program­ming of the cooking time and starting time. The control system is operated via a membrane keyboard. The pan has a variable­speed tilting facility powered by an electric motor. All types can be fitted with a mixing unit if required.

3. MAINTENANCE CHECK LIST

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.
Check contactors and relays.
The contacts must move freely without sticking or jamming. Check all contac­tors for traces of burning.
Measure the individual phase currents with a clamp-on ammeter on the power supply immediately before the connection termi­nals with the appliance switched on full and com­pare the currents with the data on the electrical sche­matic.
Inspect internal wiring. In case of defect cables Check condition of all oper-
ating foils. Optical inspection of the
whole control unit. Test all operating functions
and check that the control unit works correctly.
Check switches for easy movement and correct func­tion.
Compare the digital display of the bottom temperature with the actual value meas­ured.
Compare the food temper- ature display with the actual value.
Inspect fixation and condi­tion of all temperature sen- sors (jacket, food, deaeration, excess temper­ature) and check electrical connections.
Inspect condition and func­tion of the safety thermo- stat.
Test if all heating elements work well by measuring the indicated heating-up time or measure the current.
Check all elements of the display on the operating panel with service test 1.
Inspect fixation and condi­tion of all switches (power isolator, control, tilting, stir­rer) and check electrical connections.
In case of loose contacts B tighten contacts.
In case of defects or faults B replace contactor or relay.
Identify defective consumers (heating systems) by care­fully measuring the individ­ual currents. If major deviations are discovered

Check Fault B Remedy Check function of acoustic
signals.
Check the lid for correct shape or damage.
Check the lid hinges for correct function.
Inspect pipework and screw connections (pans with external heating) for tight sealing.
Check function of mixing unit for function. Check for leaks of water connections.
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 touch­ing 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-conduct­ing paste does not result in any substantial improvements.
Correct results can be achieved by means of infrared meas­urement using a pyrometer (e.g. Raytek's Raynger, series ST2L). To prevent reflection from the pan base, a heat-resist­ant, 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.
If the sound is offkey or no sound is heard B exchange the whole con­trol print.
If irreparably damaged B replace the lid.
If defective B disassemble, clean, grease, adjust the hinge.
In case of leakage B replace seals or pipes.
If the tap drips or if any pipes leak B replace seals.

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 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 loca­tion (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).
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 disassem­bled. 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).
Floor mountingh
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 fol­lows 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.

5. FUNCTIONAL COMPONENTS

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.
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 instanta­neous adhesion is reduced. Following applica­tion, the foil has a working temperature range from -40°F (-40°) to +248°F (+120°C) continu­ous temperature load and 356°F (180°C) short-time temperature load.
