CONNECTING THE ELECTRICITY MAINS
Before inserting the plug into the mains socket for your own safety you must take careful note
of the following precautions.
• The machine’s electrical system can only be considered
safe when it is connected correctly to an earthing system, as
provided for by the national safety regulations. The manufacturer
cannot be held responsible for any damages that may be caused
by failure to earth the system.
• For the system to be installed correctly and safely, it is
essential to provide a suitable socket which complies with the
national safety standards in force (see Fig. 2).
• Check the length of the power supply cable to make sure it is not being crushed, do not use
extension cables and, to remove the plug, first turn off the switch, then hold the plug tightly
and pull gently.
• Do not obstruct the ventilation and the heat dissipation grids as bad airing, in addition to
reducing the output and causing bad functioning, could also lead to serious damage to the

2. Adjusting the consistency:
To vary the consistency of the ice slush, turn
the knob (S) as shown in Fig. 13. Turning the
knob counter-clockwise will increase viscosity
(make the product denser). Turning the knob
clockwise will decrease viscosity (make the
product less dense).
ATTENTION: This device only changes the
consistency of the ice slush
dispensed, it does not effect the
cooling temperature.
ATTENTION: When the level of the ice slush
inside the bowl is below the
minimum, to stop the product
becoming too dense you must
switch off the cooling system
(OFF position), or top up the
bowl,
An indicator gauge for reference is located on the
back of the unit approximately 6 inches below the
adjustment knob.

CONDENSER FILTER CLEANING
ATTENTION: To guarantee the cooling system a good performance level, the routine
cleaning of the condenser filter is essential.
As explained earlier, an acoustic signal, accompanied by the word
FILT appearing on the control panel display, will warn the operator
when the filter is clogged and so must be cleaned before the
machine comes to an automatic stop.
Proceed as follows:
• disconnect the machine from the power supply;
• remove the filter as showed in Fig. 31 and clean it;
• dismount the cover (B) – Fig. 32;
• disconnect the plug (D) – Fig. 33;
• un-thread the back (E) – Fig. 33, pulling it high.
• clean the condenser with a brush if necessary (Fig.34).
You are reminded that all the operations described above
must be carried out with the machine switched off and the
power cable disconnected.
INSUFFICIENT AIR FLOW ALARM
To protect the entire cooling system, the ice slush drinks
maker is fitted with an electronic system which issues an
acoustic warning signal in the event of insufficient
ventilation or if the condenser filter is clogged with dust. In
addition to this, the words Filt and then Err will appear on the
control panel display.
If the operator does not intervene when the signal is issued,
restoring normal working conditions (i.e. ensuring better
ventilation or cleaning the filter), this electronic system will stop
the machine automatically.

Description
Sold out = Pressure switch / product presence
The “sold out” pressure switches ,set on the electro-valves, detect the presence (or not) of
product in the bag in box. The “sold out” pressure switches are not related to ANY control
board. They work INDEPENDENTLY one from the other (left bowl sold out works
independently from right bowl sold out). When the “sold out” pressure switches detect the lack
of product, they stop the mix (product and water) dispensing. In managing bowls level
condition they are active only during a bowl loading phase
Level bowl =Level probes
The “level bowl” probes function is to control and manage the product level in the bowl. They
work INDEPENDENTLY one from the other (left bowl level probes work independently from
right bowl level probes).
Cut out level bowl = overflow probes
The “cut out level bowl” probes are safety probes. Their function is to avoid bowl’s overflow if
the “level bowl” probes are out of function (both of them or just one of them). If they are
active they inhibit the “pressure and level control board”.

box, the unit works as a first filling condition and it happens the same situation
described at point 1.
3. If the “level bowl” probes are covered and the unit is switched off and then switched on,
the unit ignores the first filling condition because the “level bowl” probes are already
covered.
4. If the product inside a bag in box finishes during a managing bowl level, it is necessary
to switch the unit off, remove the empty bag in box and replace it with a new one and
then turn the unit on. The unit works as a first filling condition and, when the “level
bowl” probes are covered, the unit stops the mix dispensing in the bowl.
5. If the product inside a bag in box finishes as soon as the “level bowl” probes are
covered, the unit does not detect the end of product. As soon as the “level bowl” probes
are uncovered the “sold out” pressure switch detects the end of product and stops the
mix dispensing. After 1 minute the “pressure and level control board” lights the relative
led (out of product) on. So that it is necessary to turn the unit off, remove the empty
bag in box , replace it with a new one and turn the unit on. The unit will work as a first

Bowl Pressure Managing
The pressure inside the bowls is managed by the “pressure and level control board”.
First filling condition
In first filling condition the pressure inside the bowls is not checked until product reaches the
“level bowl” probes in BOTH the bowls. When the “level bowl” probes are satisfied in BOTH the
bowls the “pressure and level control board” begins to work and maintains the pressure inside
each bowl between 120mbar (on ) e 160mbar (off). After 1 minute and 30 seconds, if the
pressure inside the bowls does not reach 160mbar, there are 2 possibilities:
• there is no more gas in the CO2 external tank; so the “out gas” frontal led is lit and it is
necessary to turn the unit off, remove the empty CO2 tank and replace it with a new
one
• there is a lack of CO2; so the CO2 dispensing is interrupted in order to avoid the CO2
external tank run out. It is important to find out the origin of this lack.
Pressure managing
The pressure inside the bowl (between 120mbar e 160mbar) is managed INDEPENDENTLY
from “level bowl” probes. For example if the “level bowl” probes (in both bowls or just in one)
are uncovered and a bag in box is empty, the led (out of product) on the frontal panel is lit
(after 1 minute) but the pressure inside the bowl remains between 120mbar e 160mbar even if
the bag in box is not removed and replaced with a new one.

It follows some events that can happen during unit working:
1. If external tank (or tanks) is (are) empty during the first filling condition, the “sold

2. If the unit is switched off and then switched on without removing the external tank
empty (or tanks), the unit works as a first filling condition and it happens the same
situation described at point 1.
3. If the “level bowl” probes are covered and the unit is switched off and then switched

first filling condition and, when the “level bowl” probes are covered, the unit stops
the product dispensing in the bowl.
5. If product inside the external tank finishes as soon as the “level bowl” probes are
