IMPORTANT
On dispensers with more than one tank, the ON/OFF key (A) and related indicator light (B) are only present on the control panel of the right-hand tank but their
operation affects the entire appliance. Therefore pressing key (A) will turn all the
tanks on or off and, where featured, it will also turn all the lights on or off.
IMPORTANT
On dispensers with more than one tank, should you wish to turn off a single
tank, you will have to press the key for the operating mode currently in use on
the related control panel. Both the cooling and the mixer will stop and the corresponding display will show the message: OFF.
2 OPERATING PRINCIPLE
The operating principle of this dispenser is based on cooling and concurrently mixing the product inside the transparent tank. When
the product reaches negative temperatures, it begins to freeze, thereby increasing in density and therefore the effort required by the
geared motor to mix it. Using the electricity consumption value, the electronic control system is able to determine this effort and when
it reaches a set level, the solenoid valve is closed, thereby shutting off the supply of refrigerant gas to the evaporator cylinder. Since
the product is no longer cooled, it tends to melt, thereby decreasing in density and therefore the effort required by the geared motor
to mix it. When the effort drops below a set level, the solenoid valve re-opens, the refrigerant gas resumes its passage through the
evaporator cylinder and the product cools down and increases in density again. This regulation system ensures the density of the
product is kept at a set level.
Setting the density of the product to between 1 and 10 makes it possible to obtain a product with the required level of density. By
default, the maximum setting, i.e. when the density is set to 10, corresponds to consumption of electrical power of 65 watts, which
can be increased to 100 watts by starting up the machine in Service Mode and adjusting the PA02 parameter (see relative paragraph). Each density setting value corresponds to 1/10 of the value of the PA02 parameter. In addition to this, the machine checks
that the product temperature does not drop below a minimum operating temperature defined by the PA03 parameter, whose default
setting is -14 °C. This setting is useful to prevent the remaining product gradually reaching ever lower temperatures as the container
is progressively drained.
Again starting up the machine in Service Mode, it is also possible to set the rotation speed of the mixer when the product is being
prepared (PA03 parameter), when the product is ready (PA04 parameter) and when the machine is in product storage mode (PA05
parameter).
IMPORTANT
When the ice cream production operating mode is selected, the compressor is
always on. When the dispenser is turned on, after the 120-second safety delay,
the compressor starts up and always stays on.
When the product conservation operating mode is selected, the compressor is
only on if at least one of the solenoid valves is open and therefore if at least one
of the tanks requires cooling. Every time the compressor is turned off, a safety
time lapse of 120 seconds must pass before it can be restarted.
As well as the operating modes described in the Instruction Manual, the dispenser may be started up in other modes which can be
used for technical support. These modes are summarised in the table below:

3 SERVICE MODE – ADJUSTING THE OPERATION PARAMETERS
By switching on the dispenser using the master switch and holding down key A simultaneously, the machine can be started up in
service mode and make adjusting the Operation Parameters. The dispenser will function normally, but it will be possible to modify
the operation parameters and any modifications carried out will be stored in the memory for the next time the dispenser is switched
on in normal mode.
When the machine is in use, to adjust the operation parameters, hold down keys C and D simultaneously. The display will show the
code PA01 to indicate the first parameter which may be modified. Pressing keys C and D enables the selection of the parameter to
be modified. Pressing key A will then make it possible to activate the modification of the chosen parameter. The display will show
the current value of the parameter. This value can be modified using keys C and D. Pressing key A once more or waiting three seconds without pressing any keys confirms the new value and the display will return to the list of parameters. To exit the parameter
adjustment, hold down keys C and D simultaneously or do not press any key for three seconds.
IMPORTANT
On dispensers with more than one tank, the operating parameters, from PA01 to
PA10, must be set separately for each tank.

6 FUNCTIONAL TEST OF THE MACHINE
The following procedure allows to test the complete functionality of the unit:
1 Switch On the machine.
2 If in Standby set the machine in Working Mode.
3 Set all the bowls in Ice Cream Mode: the gear motors must turn regularly. The icon J flashes on the right display. The icons I
flash on all the displays.
4 After 15 seconds, when the time set by parameter PA15 is expired (delay timer of the solenoid valves, factory default 15 sec.)
the solenoid valves open (the sound "click" must be heard one time for each bowl in a short time). The icon J, on all the display,
stop flashing becoming still.
5 After 180 seconds, when the time set by parameter PA14 is expired (delay timer of the compressor, factory default 180 sec) the
compressor and the fan motor start. Now the cooling system of the machine is working and after some ten of seconds the
evaporators must begin to freeze in the front lower part. The icon I, on the right display, stops flashing becoming still.
6 If it is possible to complete this procedure with success it means that the machine works properly.
This test takes approx. 5 minutes and allows to verify the proper working of the gear motors, of the compressor, of the fan motor, of
the solenoid valves and of the electronic boards all together.
The only thing that this procedure can't allow to verify is the efficiency of the cooling system which can be reduced for example due
to a leak of refrigerant gas. In order to execute such a check, a test with product, 90 minutes long, is required.
7 PROTECTION AGAINST EXCESSIVE DENSITY
In the case of excessive product density, in order to avoid damage to the dispenser, both the freezer and the mixer will be stopped
for three minutes and one of the following messages will appear on the display: “AL03”, “AL06” or “AL08”. After three minutes, both
mixing and freezing will be reactivated and the previous density setting will be decreased by one level.
To reset the alarm message and return to the fixed display, hold down the B key for three seconds.
From serial number 1184, with the introduction of firmware versions 025 and 018, the alarm display has been replaced by the symbol
---- shown on the display.
The alarm display is possible in Service Mode or Super Service (see paragraph 3 and 4) or, during normal operation, by simultaneously pressing the + and -.
