INSTALLATION
UNPACKING
TREATMENT OF PACKAGING
BEFORE THE FIRST START-UP
POSITIONING
All of the operaons illustrated in this secon are to be exclusively carried out by specialised technicians, those who have to
organize the dierent operave sequences and the use of suitable means to act at all mes within the rigorous applicaon
of current standards regarding this maer.
The following requirements
must be met before installing
the machine in the
establishment:
1. That the network voltage coincides
with the one indicated on the
idencaon label.
2. Operang room temperature:
20°C and 40°C
68°F and 104°F.
3. Must be installed in a place
where it can be monitored by
qualied personnel.
4. It must be placed horizontally
on a solid, at and stable surface.
5. Easy access to the plug.
6. That the laws and current
technical standards are complied
with when carrying out the
installaon.
Once the machine has been received, it must be moved to the place where it will be installed:
1. Make sure that nobody is within the liing and load movement operaon radius and, in parcularly dicult situaons,
use personnel who control the movements to be carried out.
2. Moving the machine must be done by at least two people in a vercal posion.
3. Avoid bumpy routes, paying aenon to the dimensions and possible protruding parts.
4. It is prohibited to make addional cuts in the packaging.
5. Try not to damage the packaging as it could be used again in the future.
6. In the established place and to connect to the network.
Damages that the machine may suer during transport and moving are not covered by the warranty. Repair and replacement of
parts that may get damaged must be paid for by the customer.
Recycling: On the one hand, it can be subdivided according to the type of materials of which it is made up and they can be
treated according to the provisions of the rules enforced in the country where the machine is located.
Conserve for future use: On the other hand, it is possible to conserve the packaging as it might be useful for future
movements or transport of the machine.
Washing and Sanitaon: It is recommendable to carry out careful cleaning and sanisaon of the machine.
Parameter Conguraon: Perform the INSTALL procedure and congure the parameters required.

SERVING THE PRODUCT
The Push and Pull tap allows us to serve the
product in two dierent ways:
IF ICE CRYSTALS APPEAR
CLOSE PREMISES
(STANDBY MODE)
Pull: Pull the handle. (Fig. 7)
Push: Push the handle. (Fig. 8)
Select Defrost Mode: Press OPERATING
MODE Unl the display shows: DEFROST
(Fig. 9)
Allows you to defrost the product quickly. Wait
unl Defrost nishes. (During Defrost, Slush
and Stand By mode of any tank is deacvated)
Prepare Slush: Press OPERATING MODE Unl
the display shows: SLUSH (Fig. 10)
In this way, the slush always remains
homogeneous and prevents the formaon of
excessively large ice crystals.
Select Standby Mode: Press OPERATING
MODE Unl the display shows: STANDBY
(Fig. 11)
During the periods when the establishment
is closed, it is possible to use the machine in
maintenance mode. In this way, you will save
a considerable amount of electrical energy
as the compressor only operates during the
strictly required me to maintain the right
temperature for the product(max. 3ºC)
(max. 37.4 ºF).

The machine must be examined every six months (which is repeated every six months) and periodically (at least once a year)
by a specialized technician. This periodic vericaon serves to keep the security level of all installed components and the
machine itself high. In case a component is worn, it must be replaced by a new original spare part.
It is forbidden to use the machine when only one of its components is defecve or worn.
