INTRODUCTION
The manual provides the user with useful information for assessing the operation (in total safety, by making
it easy to inspect the system, herein after referred to simply with the term “machine” or “device”).
The following must not be considered as a long and tedious list of warnings, but rather as a series of instructions
to be periodically checked in order to keep the machine running efficiently in the long-term and, above all, to avoid
a succession of machine stoppages resulting from it being operated incorrectly.
It is important that all the maintenance and repair technicians and personnel in charge of dismantling the machine
carefully consult and read this manual before starting the various tasks, in order to prevent incorrect and careless
manoeuvres which could compromise the integrity of the machine or constitute a risk to personal safety.
If, after reading this manual, you have any doubts or uncertainties on how to use the machine, please do not
hesitate to contact the manufacturer or the customer care team that are at your disposal to help ensure that the
machine works correctly and efficiently.

Any operation involving the replacement of parts must be only be carried out by qualified
technical personnel who must possess the following pre-requisites:
General and technical knowledge at a high enough level to understand the content of the manual.
Knowledge of the main hygiene, accident prevention and technological regulations.
Overall knowledge of the machine, as well as knowledge about electrical and hydraulic problems
that could be encountered on-site where the machine is installed.
1.2. SAFETY INFORMATION AND PRECAUTIONS
In order to understand the manual correctly, you must have a sound knowledge of the terms and conventions
used in the documentation. The following symbols are used to draw attention to the various types of hazards and
allow them to be recognised:
WARNING
Danger to the health and safety of the personnel in charge.
WARNING
Danger of electrocution - dangerous voltage.
CAUTION
Danger of damage to the machine or products being processed.
IMPORTANT
Important instructions or information about the product.

USE AND INSTALLATION MANUAL
Only specialised personnel are authorised to operate the machine.
Dispose of the packaging of the parts and any bags or boxes responsibly.
Any parts that are replaced must be disposed of in accordance with current regulations.
DANGER! The tasks described in this manual are reserved for specialised personnel, authorised
by the manufacturer, to perform them in compliance with the regulations in force in the country of
use and the relevant system and work safety standards.
DANGER! Before carrying out any work on the equipment, carefully read all the indications given
in this booklet and in the use and installation manual supplied with the equipment.
DANGER! This manual must be kept in a safe place for future use.
DANGER! Always work when you are in perfect physical condition and wearing personal
protective equipment (safety shoes, gloves, goggles, etc.).
DANGER! When working on the equipment, make sure that there are no unauthorised persons,
inflammable or explosive material and objects that could hinder operations, in the work area.
DANGER! Before carrying out any work on the equipment, ALWAYS disconnect the water and
electricity supply (danger of fatal electrocution!).
DANGER! If any parts have been replaced, do not leave their packaging unattended (e.g. plastic
bags): danger of suffocation for children and animals. Dispose of the packaging according to local
regulations.
DANGER! Any work, tampering or modifications not expressly authorised, which do not respect
the provisions indicated in this manual, could cause harm, injury or fatal accidents and will void
the warranty.
DANGER! Make sure the premises are well ventilated during all work on the equipment.
DANGER! After the work has been completed and before starting up the machine:
make sure that all parts and any safety devices that have been dismantled are correctly
reassembled;
make sure that the machinery has been correctly connected to the electricity supply;
tell the operator about any new devices on the machine.
DANGER! Surfaces get hot during use and may remain hot for some time after the machine has
been switched off, therefore, any maintenance work should be carried out after the machine has
cooled down completely.
DANGER! Some of the metal sheets have sharp inner edges: always wear gloves.

USE AND INSTALLATION MANUAL
1.2.1. PERSONAL PROTECTIVE EQUIPMENT
Table summarising the personal protective equipment (PPE) to be used during the various stages of the machine’s
life cycle.
1. Use heatproof gloves that are suitable for contact with water and the substances used (refer to the safety data sheet of the substances
used to check for any other PPE). Remember that failure to use the personal protective equipment by the operators, specialised personnel or
any other persons assigned to use the equipment could lead to exposure to chemical hazards and cause health problems (depending on the
model).
1.2.2. GENERAL INFORMATION
•The equipment is fitted with electrical and/or mechanically-operated safety devices to protect the operators
and the machine. Consequently, the maintenance technician must not remove or tamper with the above-
mentioned devices without taking adequate precautions. The manufacturer declines all responsibility for any
damage caused by tampering or by failure to use the safety devices.
•Do not make any changes to the spare parts supplied.
•The manual contains a number of diagrams illustrating the machine, or parts thereof, without the protective
devices or with the protective devices removed. This is for explanatory purposes only. Do not use the machine
without the protective devices or with the protective devices disabled.
•Switch the machine off and disconnect it from the water supply in the event of a breakdown or faulty operation.
•Do not use products (even if diluted) which contain chlorine (sodium hypochlorite, hydrochloric or muriatic
acid, etc.) to clean the equipment or the floor underneath it.
•Do not use metal tools to clean the steel parts (metal brushes or scouring pads such as Scotch Brite).
•Do not allow oil or grease to come into contact with plastic parts. Do not allow dirt, grease, food or other
residue to get deposited on the machine.
•Do not spray water or use steam to clean the machine.

USE AND INSTALLATION MANUAL
1.2.3. RESIDUAL RISKS
Using the machine involves some risks which cannot be completely eliminated through design or with the
installation of adequate protective devices. However, the manufacturer has undertaken to inform the operators of
these risks in this manual by specifically indicating the personal protective equipment to use. When repairing the
machine, adequate space has been provided to limit these risks.
To maintain these conditions, the areas around the machine must always be:
- obstacle-free (e.g. ladders, tools, containers, boxes, etc.);
- clean and dry;
- well-lit.
For the sake of providing the customer with comprehensive information, the residual risks remaining on the
machine are indicated below: these actions are deemed inappropriate and are, therefore, strictly forbidden.
Residual risk
Description of hazardous situation
Slipping or falling.
The operator may fall due to water or dirt on the floor.
Burns/grazes (e.g. from hot components).
The operator deliberately or involuntarily touches parts
inside the machine without wearing protective gloves.
Electrocution.
Touching live parts while servicing the machine when the
electrical control panel is powered.
Overturning of heavy loads.
When handling the machine or the packaging that
contains it, inadequate lifting systems or accessories are
used or the load is unstable or unbalanced.
Mechanical features of safety devices, risks
•The machine does not have any sharp or protruding parts. The protective devices for the mobile and live
parts are screwed onto the structure and cover to prevent accidental access.
Protective devices installed on the machine
•The protective devices on the machine are:
fixed protective guards (e.g. casings, covers, side panels, etc.), fixed to the machine and/or frame with
screws or quick-release connectors which can only be removed or opened with specific tools.
