IMPORTANT WARNINGS AND ADVICE
This instruction manual represents an integral part of the equipment and must be kept readily
available for use. Read the warnings contained herein carefully before installing and using this
equipment. In addition to offering information concerning routine maintenance for the ice slush
drinks machine and technical back-up for troubleshooting, this manual aims to help the user
make the most of the machine’s potential, adapting it to suit the specific needs of the various
countries it will be used in. Modifications or attempts to modify the equipment will not only
result in the forfeiture of the guarantee, but are also extremely dangerous.
The maintenance operations must be carried out by qualified professionals. Never attempt to
repair the machine yourselves as the intervention of non-qualified persons, as well as being
hazardous, could also lead to serious damage to the machine.
ATTENTION: Before starting up the machine it’s necessary to perform all the cleaning
and sanitation procedures.

TRANSPORTATION INDICATIONS
To prevent the oil contained in the compressor from flowing out into the cooling circuit, the
equipment must be transported, stored, and handled in a vertical position, as per the
indications given on the packing. The wooden pallet, equipped with housing for the lifting
forks, allows the packed equipment to be moved using normal handling and hoisting means.

INSTALLATION
1. Release the equipment from the packing, then slide it off
upwards (see Fig. 1). The machine has to be installed in level
with horizontal plane;
2. Checking the machine identification after removing the
packing, you must check that the equipment you have
received is exactly as you ordered, making sure the
specifications indicated on the invoice or the delivery note
are identical to those on the data plate.
Fig. 1
3. Equipment accessories
On opening the packing you will find the following accessories inside the bowls:
• this instruction manual;
• 1 tube of Vaseline to be used for the maintenance machine the requires;
• 2 bags, each one containing a drip tray
• 2 evaporator frontal seals
4. Positioning - make sure the machine’s bodywork is well ventilated (20cm (8”) all around at
least ) and do not install it near heat sources.
We recommend you keep the room temperature at between 59°F (15°C) and 90°F (32°C).
IMPORTANT: All the pieces of packing must be kept out of reach of children as they
represent potential hazards.

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
equipment.
• Plug:

BOWL LOADING OPERATIONS
VFCB (PRE-MIX)
• Switch on the machine’s main switch.
• Put the switch (A) into position 1 – Fig. 5 - (switch
A controls the flow of the product in the bowls).
• The machine’s bowls will now fill up until the
maximum level is reached.
• Proceed to start up operations.

• Loosen the valve flanges screws as indicated in the fig.5A
without disconnecting them from the inferior flange;
• Remove the superior flange (C1) as indicated by the arrow in
the fig.5A;
• Leave the inferior flange (D1) on the bowl surface, it will be
easier to reassemble it after the brixing procedures.

• Switch the machine’s main power switch to the
ON position.
• Make sure the switch (L1) is in the OFF position
(0) – Fig. 6. (Switch L1, A in fig.5, controls the
flow of the products in the bowls)
• Turn mixing motors OFF immediately. Do not
run units with bowls empty
• Using an 8 mm socket wrench (E1), loosen the
nut that holds the post-mix valve (D1).
• Lift the post mix valve (D1) up slightly and turn
it towards the outside. Leaving nozzle (F1) and
coupling attached to the bowl.

• Now rotate the valve assembly 90 degrees and slide to
the outside of the machine. Tighten the 8mm nut using a
socket wrench (E1) – Fig. 7;
• Assemble the valve plate (A1) and the black knob
(B1) (you can find them inside the machine package)
as indicate in the fig.8;
• If you need to do the brixing procedures using the
calibrator/separator you have to assemble it instead
the black knob;
• Checking and adjusting the water flow is most easily
done by first disconnecting the syrup bib.

•
If necessary apply the calibrator/separator relative measuring cup (H1) and push the button
(or the micro switch) on the valve (l 1) until both the soda water and the syrup run into the
measuring cup separately (Fig. 9).
•
Adjust the water flow to the minimum level in order to reduce the inlet pressure. Turn the
water adjustment screw on the flow control counter clockwise until the minimum position to
decrease water flow (clockwise to increase it).
•
Reconnect the syrup.
•
Dispense product into a cup or into the
measuring cup by depressing the micro switch
on the valve. Check brix using a refractometer or
the measuring cup. The brix should be set to
13% ± 1%. To increase the brix adjust the syrup
adjustment screw on the valve clockwise to
increase syrup flow or counter clockwise to
decrease syrup flow.
CAUTION: Do not turn the syrup flow
control counter clockwise to far .
•
When the brix has been set to specification,
reposition the valve to its original setting &
tighten retaining nuts.
•
Repeat the operation for the second bowl.
•
Once the adjustments have been completed for each bowl, place the switch (L1) in the “ON”
position.
•
Both bowls will fill until the level sensor is activated.
•
Turn mixing motors “ON” (switch located on the control panel). The dispenser has built in
delays for compressor & bowl fill switch.
•
NOTE: During initial filling it is normal for some foaming to take place. The bowl level
management will adjust as the product freezes & the foam will dissipate.

“FILTER CLEANING” Alarm
A filter cleaning alarm will activate when the unit is running hot due to insufficient internal air
circulation. When this occurs a “Filt” message will appear on the touch pad LED display readout
and an intermittent audible tone will also sound to alert the operator of this condition.
The “Filt” message will appear when the alarm activates (a beeping sound every 4-5 seconds).
To determine the condition that caused the alarm, see list of conditions below:
• Condition: The filter is dirty and needs to be cleaned.
Corrective Action: Clean and replace filter following instructions(Removing and Cleaning Filter).
• Condition: The unit is positioned too close to a wall or other object restricting air flow and
causing the machine to run at a higher temperature.
Corrective Action: Reposition unit to maximize ventilation space (Installation Instructions).
• Condition: The filter is not properly installed.
Corrective Action: Properly install filter (Removing and cleaning filter).
• Condition: The unit has been installed near a heat source, such as a coffee machine, ice
maker or cold beverage machine which expels hot air from its vents, causing the machine to
run at a high temperature (installation near a heat source should be avoided)
Corrective Action: Reposition unit to maximize ventilation space.
“SYSTEM OVER TEMPERATURE” Alarm
A system over temperature alarm will activate as a safety precaution when the unit has
overheated to protect the compressor.
• The system automatically goes to “OFF” status where the compressor’s operations is
stopped, while augers will keep working to avoid forming ice blocks.
• When this occurs an “Err” message will appear on the touch pad LED readout accompanied
by a continuous buzzer sound to alert the operator of this condition.
• When this alarm activates, turn off all switches. Then determine the condition. (See “Filter
Cleaning” Alarm Section for Conditions and Corrective Actions)
