II - OPERATING INSTRUCTIONS
This unit is designed to be used as a cooking appliance in a
watery medium and must be used exclusively by qualified
personnel in the manner set down in this instruction manual.
All inappropriate uses are dangerous.
1 - IMPORTANT
• Read this booklet carefully, as it gives important installation,
safety, use and maintenance suggestions.
• Keep this booklet handy for any future reference.
• The installation of the appliance and its adaptation to other types
of gas must be carried out exclusively by qualified personnel.
• To limit energy consumption (electrical, water) the appliance
should not be used for long periods when empty or in conditions
that are unfavourable for optimum efficiency (e.g., with lid open,
etc.).
• For any repairs, turn only to a technical assistance centre
authorized by the manufacturer and demand that only original
spare parts be used.
Failure to comply with the above recommendations could compro-
mise the safety of the appliance.
2 - STARTING THE APPLIANCE
Before putting the appliance to use, wash the inside of the pot
carefully with warm water and detergent and rinse freely.
ATTENTION
Never put the appliance to use if the water jacket is not full.
Failure to comply with this essential point would seriously
overheat and damage the heating elements and the other
internal components.
3 - FILLING THE WATER JACKET
Fill the jacket with water with a hardness of not more than 7°F as
follows:
• Open the maximum level valve "D".
• Remove the jacket inlet threaded plug "F" located on the safety
unit.
• Let the softened water flow through the jacket inlet until a steady
trickle of water flows through the valve "D". This is a sign that the
water in the jacket is at the maximum level.
• Close the valve and put the threaded plug "F" back in place.
IMPORTANT
At the start of every day and with the appliance cold, check
that the water in the jacket has not dropped below the mini-
mum level.
This check is carried out by opening the minimum level control
valve "E", from which water should always flow freely. If this is not
the case, immediately add water up to the maximum level.
4 - FILLING THE TANK
• Check that the large discharge tap "A" is closed.
• Fill the tank by opening the two taps "B" or "C" of the hot and cold
water. The maximum water level in the tank must be at least 4
cm lower than the rim, and if necessary still lower if there is a
danger (in the autoclave models) that the food being cooked
could clog the safety valve located on the lid.
• Close the lid.
ATTENTION
When closing the autoclave lid, the clamps "O" must be tight-
ened by operating on them, gradually and uniformly, in a dia-
metrically opposed progression.
Start the clamp opening operation, only after checking that
there is no pressure inside the tank, by pressing on the vent
button on the safety valves "P" on the lid. Loosen the clamps
partially and in a gradual manner.
Once a day, open the lid and let go of the handle to check that it
remains in the raised position. Every six months, check the condi-
tion of the lid balancing spring.
Always keep your hands away from under the raised lid.
5 - HEATING
• After having filled the jacket and the pot with water, connect the
power supply through the automatic circuit breaker installed
upstream of the appliance.
• Turn the power control knob "J" to "ON".
The signal lamp "L" lit indicates that the appliance is in operation.
• Select the heating power by turning the power regulator knob to
the desired power settings, shown by the symbols on the knob
itself.
• When the steam pressure in the jacket approaches 0,45 bar
(maximum value), the safety valve "H" will start to vent.
• At this point, depending on the type of food being cooked, lower
the heat input by rotating the power knob "J" to a lower position,
until the valve "H" stops to vent steam, so as to avoid a rapid loss
of the water contained in the jacket.
6 - SWITCHING OFF THE APPLIANCE
• Turn the power knob "J" to position "OFF" and disconnect the
automatic circuit breaker installed upstream of the appliance.
7 - END OF COOKING
At the end of the cooking cycle, open the lid carefully to avoid
being scalded by the steam or by contact with hot parts.
• To discharge the contents of the pot, open the large discharge
tap "A".
8 - JACKET SAFETY AND CONTROL DEVICES
The indirect heating pots (bain-marie) are provided with a safety
unit consisting of:
•
Pressure indicator "G" showing the steam pressure inside the
jacket (Fig. 6);
•
Depressurization and vent valve "I" which allows the exit of the
air contained in the jacket;
•
Spring safety valve "H" calibrated for a maximum pressure of
0,45 bar; the valve starts to vent steam when the pressure inside
the jacket approaches the above mentioned value;
•
Threaded plug "F" to fill the jacket with water.
•
Working pressure switch (PS1), calibrated at 0.35 bar: it makes
it possible to keep the jacket pressure adjusted in a range very
close to this value.
Check the efficiency of the safety valve a first time upon
installation of the unit and afterwards at least once every six
months.(Just lift the knob to make sure that the device it lifts
does not stick to its seat. If this happens lift the device for a
few times to obtain the complete release.)
9 - SAFETY THERMOSTAT
The appliance is provided with a safety thermostat which trips and
cuts off power to the heating elements if the water in the jacket
drops below the minimum level.
To reset the operation of the appliance, after adding softened water
into the jacket unscrew the protection plug and press the red button
"K" located on the pot control panel (Fig. 6).
