Granita Making If it is pressed quickly, it allows decreasing
key (D) density. If it is pressed one second while the
machine is running in the Product Preserva-
tion mode, it allows switching to the Granita
Making mode.
If it is pressed one second while the machine
is running in the Granita Making mode, it
allows resetting possible alarms.
The display shows the following icons, too:
Solenoid valve icon (E) It shows the condition of the cooling
solenoid valve.
Icon off: solenoid valve closed
Icon flashing: delay timer on
Icon on: solenoid valve open
Product Preservation If it is on, it shows that the machine
Icon (F) is in the Product Preservation mode.
Granita making Icon (G) If it is on, it shows that the machine
is in the Granita Making mode.
Density bar (H) It shows the set density value and
the alarms.
HOW TO START THE DISPENSER
Turn the main switch to position I. Pilot light (A) will be on
showing that the dispenser is ready to work.
Keep key (B) pressed until the dispenser starts.
Select the operation mode and the desired product density by
means of keys (C) or (D).
ADDITIONAL FUNCTIONS
LIGHT SWITCHING ON/OFF
By pressing key standby (B) twice quickly, lights can be turned
on and off. When the machine is in the Granita Making mode,
lights are always on; when the machine is in the Product
Preservation mode, lights are always off.
DENSITY ADJUSTMENT
When the machine is working in the Granita Making mode, it is
possible to adjust product density by pressing keys C or D
briefly.
The factory set value is 8, which is convenient to make granitas.
WASHING MODE
When the dispenser is in the Product Preservation mode, by
pressing key C for two seconds, the Washing mode is enabled.
In such a case, the mixer turns but cooling is disabled.
Use this mode during the machine washing and sterilization to
prevent the cleaning solution from cooling.
By pressing any key, the dispenser exits from the Washing
mode and returns to the Product Preservation mode.
ALARM DISPLAY
If a fault occurs during the dispenser operation, an alarm
message will be displayed. One of the elements on the density
bar will flash showing the corresponding alarm number. To find
a detailed alarm list, please refer to the Service Manual.
COMPRESSOR CONDITION
Element 1 of the density bar of the right bowl shows the
compressor operation condition:
- Off: compressor off
- Flashing: start delay timer on
- On: compressor on
KEYBOARD LOCK
It is possible to lock the keyboard to prevent access to the
dispenser controls by keeping keys C and D pressed together
for two seconds.
By pressing keys C and D at the same time again, the keyboard
is unlocked.
5. 2 OPERATION HELPFUL HINTS
1 The time required to obtain the cooling of the product varies
depending on several factors such as the ambient temperature,
the initial temperature of the product, its sugar content (degrees
Brix) and fat content and the density adjustment.
2 Topping up the containers with product that is already pre-
cooled further increases the efficiency of the dispenser.
3 To further reduce recovery time and thus increase the
autonomy of the dispenser, fill up the tanks when the level of
product has fallen to the halfway point of the evaporator.
4 To store the product correctly, the distributor must also
operate at night, at least in the PRODUCT STORAGE position.
5 Night operation in the PRODUCT STORAGE position also
eliminates the possible formation of ice (due to condensation of
atmospheric moisture) on the outside of the containers.
6 Never turn off the dispenser when there is product in the
containers. If not cooled, the product may deteriorate.
Furthermore, unless it is mixed, it may stick together and form
blocks of ice. If the mixer is restarted in these conditions
(without waiting for the ice to melt), the dispenser may be
damaged.
7 All dispensers of this kind must emit heat. If, however, this
emission seems excessive, check that no source of heat is
located near the dispenser itself and, in particular, near the grid
panels. Also make sure that the airflow is not impeded by the
proximity of walls, boxes or similar. Leave at least 15 cm free
space around the dispenser. Finally, check that the filter
located below the rear panel is clean.
ATTENTION
The access to the service area is restricted to persons
having safety/hygiene knowledge and practical expe-
rience on the appliance.
8 The product is for use with confectionery only.
5. 3 CLEANING
1 Cleaning and washing are essential to guarantee the
perfect preservation of the taste of the product and the
maximum efficiency of your dispenser. The procedures
described below should be considered general in nature and
may vary due to the health regulations in force.
2 Before disassembly for washing, the dispenser must be
emptied out of the product. Proceed as follows:
- use the keypad to select the CLEANING operating mode
- if necessary, wait until the product becomes liquid
- place a container under each tap and empty the containers
- fill the containers with water and allow the dispenser to
operate in CLEANING mode for a few minutes. Then empty the
containers.
- hold down key A to switch off the dispenser
- turn the ON/OFF SWITCH to OFF
