8. START-UP PROCEDURES AND
OPERATING INSTRUCTIONS
!IMPORTANT!
BEFORE STARTING THE MACHINE, CARRY OUT
THE CLEANING AND SANITISING PROCEDURES
DESCRIBED IN CHAPTER 9.
- Dilute and mix the product in a separate
container according to the manufacturer’s
instructions (see fig.3).
NOTE: “mix” is the result of the blending
between water or milk with the powder to
make soft serve creamy product, sorbets,
and similar products or hot creams or
chocolates.
While in the left hot barrel it is possible to
introduce maximum 2 litres of product, filling
the centre and right frozen ones it is better to
avoid introducing more than 1.5 litres of
mix inside the bowl. This kind of products
have a not negligible overrun during their
freezing process and for this reason it is
important to control it in order to avoid to go
over the bowl maximum level (please see the
chapter about the overrun calculation).
- Pour the mix obtained into the bowl (see
fig.4).
- Restore the transparent cover.
Note -----------------------------------------------
Each bowl is equipped with a very efficient
safety mechanism designed to protect the
operator; it is activated when cover is lifted.
This device automatically and immediately stops
all moving parts.
If the cover is not correctly positioned, the
correspondent mixing system will not
work.

central and right barrel.
C switch activates the right side auger
rotation designed to freeze the product.
G switch activates the central side auger
rotation designed to freeze the product.
D switch activates the left side auger
rotation designed to warm up the
product.
!WARNING!
In case the corresponding auger will not start
rotating once one of the C, G or D switches are
activated, check for the corresponding lid
correct positioning, each bowl is equipped with a
very efficient safety mechanism, if the lid is not
correctly positioned, the machine will not work.
!WARNING!
Both the refrigerating and the heating system of
each bowl could be activated only if the
correspondent auger is rotating.
FREEZING SIDE FUNCTIONING
- In order to activate the refrigerating system
and to regulate the product consistency, it is
necessary to use the buttons + and -on the
control board (fig.9); operating on the + button,
the number of lighted LED will increase with the
product consistency; operating on the - button,
the number of lighted LED will decrease with the
product consistency (fig.9).

NOTE: when all the LED are switched off the
refrigerating system is not working and the
product is not cooled.
NOTE: when the unit is switched off the
electronic board will keep in memory the last
setting, for this reason the unit will restart in
the same operating mode when switched on
again.
!WARNING!
The refrigerating system is activated when at
least one LED is switched on; in order to avoid
any damage, before activating it, is necessary
to fill up the bowl; failure to do so could damage
the unit.
Important
Do not use the unit with the refrigerating
system activated (this means in both freeze or
defrost mode) with water or sanitizer in the
bowl, the machine will be damaged.
HEATING SIDE FUNCTIONING
- In order to activate the heating system it is
necessary to activate the E switch (fig.10)
considering that if the correspondent auger is
not rotating the heating element will not work.
NOTE: when the heating element is working the
red light F is turned on (fig.10); the heating
system warms up the product until the desired
temperature and keep it at this value with
ON/OFF cycles; for this reason, during the
functioning the light will alternately turn on and
off.
NOTE: the machine is equipped with an internal
thermostat in order to regulate the product final
temperature, the maximum value that is
possible to be set is 80°C.

11.SOFT SERVE ICE CREAM
INFORMATION
OVERRUN
While the product is frozen in the bowl, its
volume increase; to control overrun is important
as too much of it could go over the bowl
maximum level.
To correctly measure overrun carry out the
following steps:
- Place an empty container on the scale and
adjust your scale to zero;
- Remove the container from scale and fill it
with liquid product to the top. Weigh container
and record;
- Replace liquid product with frozen one, strike
off the excess of it so it is even with the top of
the container and measure the weight;
- Use the following formula to figure overrun
percentage:
“Weight of liquid mix minus weight of frozen
product divided by the frozen weight. Multiply
by 100””
Example:
Weight of half litre of mix: 530g;
Weight of half litre of frozen product: 380g;
Difference:150g;
150/380=0.4
0.4x100=40% overrun
