UNPACKING
IMPORTANT
Prior to starting this procedure, ensure that the shipping carton does not show any evidence of
damage due to dropping or mishandling. This may indicate that the dispenser was damaged during
transit and/or delivery. If any damage is visible on the shipping carton, indicate this on the shipping
receipt.
You can now proceed in the unpacking process by first carefully cutting the plastic strapping which
secures the carton top and bottom. After cutting these straps, lift the carton top straight up and off
of the dispenser.
After lifting the box off the machine, carefully remove the styrofoam from the sides of the machine.
Next remove the four plastic legs, technical and instruction manual, and any other items found in
the mix tanks.
POSITIONING THE MACHINE
Prior to choosing a location please keep in mind that your dispenser should be readily accessible
for periodic maintenance and have adequate space for necessary air flow. After selecting a
location, you are now ready to place your dispenser.
Place the machine at the desired location. Make sure that there is enough space for ventilation on
both sides (about 8” on each side for 2 and 3 bowl units). Carefully lay the machine on its back and
screw the legs to the bottom. Gently tip machine onto its feet.
To ensure the highest quality in the shipping of your unit, we have left the plastic on both the unit
and the drip trays for protection against scratching in transit. Please remove before operating
your machine.
Install the drip pans and cover grates onto the front of the unit.
IMPORTANT
Before connecting power to the machine, check the label on the back of the machine to verify the
voltage and amperage draw of the unit and then do the same for the electrical outlet. Carefully
inspect the power supply cord on your dispenser for any possible damage which may have
occurred during transportation. If ANY damage is visible, DO NOT plug the machine into the power
supply, contact your authorized service agent to replace the power cord.

pull the spiral (Figure 5) forward
(arrow A) and take the head out of
the shaft end (#2).
2.2. On the spiral there is a silicone gasket
(#4) to make the axis leak-proof. Pull
it forward (C) and clean (#4) with
warm water.
4 CLEANING THE SPIRAL
Figure 5
After following the procedures for removing the
spiral, remove the bowl gasket (Figure 6, #1)
from the holder by pulling forward and the
evaporator (#3) will be released for cleaning.
Once all of the elements have been
disassembled proceed to clean with nonabrasive neutral pH detergent. Use a cloth or a
sponge to avoid scratching the bowl and other
elements.
Figure 6

Granita Machine Operation and Instruction Manual
5 CLEANING THE DRIP TRAY(S)
The front drip tray(s) (Figure 7)
should be emptied daily or more
frequently if necessary. To remove
the drip pan, push the pan slightly
upward (arrow A), then bring it
forward (arrow B) and remove the
grid (arrow C). Put the grid (#2)
back on the tray and place the
spigots (arrows F) in the holes
(arrows D, E and G) on the front
panel (#3).
6 CLEANING THE SPIGOT (Fig.8)
For machines with a handle locking system,
remove the spigot padlock and then take the
locking spigot rod away (#8 – arrow I), remove the
fastener (#7 – arrow J), disconnect the dispensing
handle (#1 – arrow K). By pushing upward (arrow
L), take the spring (#3) out from its holder (#2 –
arrow M), then push the piston downward (#6 –
arrow N), remove the o-ring (#5 – arrow P) and the
special gasket (#4 – arrow Q).
Figure 7
Proceed to clean everything with water and neutral
soap, rinse and reassemble after lubricate without
damaging the gaskets as follows: put in place the
special gasket (#4 – arrow A), put the o-ring (#5)
back in its piston slot (#6 – arrow C), insert the
spring (#3 – arrow D), put the cap in place (#2 –
arrow E), put the handle in place (#1 – arrow F),
insert the fastener (#7 – arrow G), and if you want
to lock the spigot, insert the locking spigot rod (#8
– arrow H) and lock.

C) following the direction of arrow B.
4. Assemble the spiral (Figure 5). Lubricate with
food grade lubricant the silicone gasket (#4)
and insert it in the head of the spiral (C). Insert
the spiral (#1) around the evaporator (#3) and
fit the head in the shaft by turning slightly until it
is placed in its setting.
5. To replace the bowl push backward until the
gauge notch fits in its place inserting the head
of the spiral in the stainless tube end.
Please note
8 CLEANING THE CONDENSER
At least once a month, depending on the working
conditions (presence of dust, grease, etc.) we
recommend to clean the condenser.
First of all, you need to disassemble the left side
panel (2, 3 and 4 bowl model), or the back panel (1
bowl model), by unscrewing them.
Brush off dust and dirt with a soft-bristled brush. Be
careful not do damage the ribs (see Fig. 10).
Please note: a clean condenser is essential to the
operation and longevity of the unit and they should
contact there Local service company for advise on
a preventive maintenance program for this and all
refrigeration equipment.
: The bowl gasket must be wet. This allows the bowl assembly easier.

Granita Machine Operation and Instruction Manual
HOW TO OPERATE
1. Once the bowl has been cleaned, fill the tank with the desired liquid product (3 gallons). Do not
overfill the tank. NOTE THAT WHEN READY, SLUSH OCCUPIES MORE VOLUME THAN
THE LIQUID (approximately 3.5 gallons of slush). Be sure to consider product ratio (not
exceeding 3 gallons total mix for slush) before mixing or pouring product into tank. IN
ORDER TO KEEP YOUR MACHINE IN GOOD WORKING CONDITION KEEP YOUR
MACHINE FULL.
2. If using natural products as a base (coffee,
lemon juice, orange juice, etc.), it is required
that 5 to 7 oz. of sugar per gallon be added.
Follow the dilution instructions on the bottle. In
general the brix ratio of the product solution
shouldn’t be less than 12.
3. To operate, press main power switch and
agitator switch to ON position (Figure 11).
NOTE: The agitator switch must be to ON
position before setting to liquid or slush
mode.
LEFT RIGHT
3.1 For slush, press the cooler switch to
bottom position ( II / ).
3.2 For liquid, press the cooler switch to up
position ( I / ) . If the machine is being
used as a liquid cooler, it is provided with
an inside thermostat for controlling the
liquid temperature.
Note that your machine is equipped
with a time delay relay that provides for
a four minute delay from the time of the
initial start. This is to prevent the
compressor from short cycling. Once
the compressor is ON, the green light
will be on.
Note: The cooler switch is a three position
switch and in order to have the compressor
off, all the cooler switches need to be in the
middle position.
4. To illuminate the transparency on top of the unit
and the product in the bowl press the display
light switch to down position ( I / ).
CAUTION: IF THE MACHINE IS STOPPED AT
NIGHT WITH ICE IN THE TANK, REMOVE ALL
ICE SLABS BEFORE STARTING.

LIQUID DENSITY ADJUSTEMENT
To adjust the density/consistency of the slush there is an
adjustment knob (Figure 12, #2) at the rear, right corner
of the dispenser (#1).
Turn the knob right (clockwise) or left (counter clockwise)
(arrow C and B) The consistency indicator (#4) will go up
or down (arrow D and E)
To firm up the product, turn the set knob counter
clockwise, which will move the indicator down to a higher
number position
To soften / warm up the product, turn the set knob
clockwise, which will move the indicator up to a lower
number position
NOTE: when using a new product, or on initial start up, it
is recommended that you set the consistency indicator to
the lowest/warmest setting and increase as desired.
Please note that the machines are pre-set at the factory
at a medium setting (number 2.5)
