C.2 Characteristics of power supply
The AC power supply to the machine must meet the following conditions:
• max. voltage variation ± 6%
• max. frequency variation ± 1% continuous ± 2% for a short period.
Harmonic distorsion, unbalanced three-phase supply voltage, voltage pulses, interruption, dips and the other electric character-
istics must respect the provisions of point 4.3.2 of Standard EN 60204-1 (IEC 60204-1).
WARNING
The machine's power supply must be protected against overcurrents (short
circuits and overloads) by fuses or suitable thermal magnetic circuit breakers.
A suitable high-sensitivity manual-reset differential omnipolar thermal-
magnetic switch with contact gap enabling complete disconnection in
category III overvoltage conditions and complying with the current regula-
tions, must be installed between the power cable and the electric line.

WARNING
For protection against indirect contacts (depending on the type of supply
provided for and connection of earths to the equipotential protection circuit)
refer to point 6.3.3 of EN 60204-1 (IEC 60204-1) with the use of protection
devices that ensure automatic cut-off of the supply in case of isolation fault in
the TN or TT systems or, for IT systems, the use of isolation controllers or
differential current protection devices to activate automatic power disconnec-
tion (an isolation controller must be provided for indicating a possible first
earth fault of a live part, unless a protection device is supplied for switching off
the power in case of a such a fault. This device must activate an acoustic and/
or visual signal which must continue for the entire duration of the fault). For
example: in a TT system, a differential switch with cut-in current (e.g. 30 mA)
coordinated with the earthing system of the building where the machine is
located must be installed ahead of the supply.
D TRANSPORT, HANDLING AND STORAGE
D.1 Introduction
Transport (i. e. transfer of the machine from one place to
another) and handling (i. e. transfer inside workplaces) must
occur with the use of special and adequate means.
WARNING
Due to their size, the machines
cannot be stacked on top of each
other during transport, handling
and storage; this eliminates any
risks of loads tipping over due to
stacking.
NOTE!
Specialised personnel must:
• have specific technical training and experience
in the use of lifting systems;
• have knowledge of the safety regulations and
applicable laws in the relevant sector;
• have knowledge of the general safety rules;
• ensure the use of personal protection equip-
ment suitable for the type of operation carried
out;
• be able to recognise and avoid any possible
hazard.
D.2 Transport: instructions for the carrier
WARNING
Do not stand under suspended
loads during loading/ unloading
operations. Unauthorised per-
sonnel must not enter the work
area.
The weight of the appliance
alone is not sufficient to keep it
steady.
NOTE!
The transported load can shift:
• when braking;
• when accelerating;
• in corners;
• on rough roads.
D.3 Procedures for handling operations
For correct and safe lifting operations:
• use the type of equipment most suitable for characteristics
and capacity (e.g. electric pallet truck or lift truck);
• cover sharp edges;
Before lifting:
• send all operators to a safe position and prevent persons
from entering the handling area;
• make sure the load is stable;
• make sure no material can fall during lifting. Manoeuvre
vertically in order to avoid impacts;
• handle the machine, keeping it at minimum height from the
ground.
WARNING
For machine lifting and anchor-
ing, do not use movable or weak
parts such as: casings, electrical
raceways, pneumatic parts, etc.
D.4 Shifting
The operator must:
• have a general view of the path to be followed;
• stop the manoeuvre in case of hazardous situations.
WARNING
Do not push or pull the appliance
to move it, as it may tip over.
D.5 Placing the load
Before placing the load, make sure the way is free and that the
floor is flat and can take the load. Remove the appliance from
the wooden pallet, move it to one side, then slide it onto the
floor.

20
D.6 Storage
The machine and/or its parts must be stored and protected
from damp, in a non-aggressive place, free of vibrations and
with room temperatures between -10℃and 50℃. The place
where the machine is stored must have a flat support surface
to avoid deforming the machine or damage to the support feet.
WARNING
Appliance positioning, installa-
tion and disassembly must be
carried out by specialised
personnel.
CAUTION
Do not make modifications to the parts
supplied with the appliance. Any missing
or faulty parts must be replaced with
original parts.
E INSTALLATION AND ASSEMBLY
E.1 Introduction
To ensure correct operation of the appliance and maintain safe
conditions during use, carefully follow the instructions given
below in this section.
WARNING
The above operations must be
carried out by the specialised
personnel in conformity with the
current safety regulations,
regarding the equipment used
and the operating procedures.
Before moving the appliance
make sure the capacity of the
lifting equipment used is suitable
for its weight.
E.2 Customer responsibilities
The Customer must provide for the following:
• installation of an adequate electrical power supply ahead of
the appliance, according to the equipment’s technical
specifications (C.1 Main technical characteristics and C.2
Characteristics of power supply);
• the equipotential connection of the workplace electrical
system to the metal structure of the machine by means of a
copper cable of adequate section (see position “EQ“ in
Installation diagram);
• adducting for the electrical connection between the work-
place electric panel and the equipment;
• the water supply and drain connections and other con-
nections as indicated in C.1 Main technical characteristics
and in the paragraph E.8 Plumbing connections;
E.3 Characteristics of the installation place
The machine is designed for installation in professional and
not domestic-type kitchens. Water collection traps/ metal
grates must be arranged in the floor at the machine discharges
(see the Installation diagram), possibly replaceable with a
single water trap sized for a flow rate of at least 3 l/s.
CAUTION
Do not install the appliance over 2000
meters above sea level.
E.4 Appliance space limits
• A suitable space must be left around the appliance (for
operations, maintenance, etc.).
• The passages enabling personnel to operate on the
appliance must be at least 50 cm wide, except at the rear
of the appliance.
• This space must be increased in case of use and/or transfer
of other equipment and/or means or if exit routes are
necessary inside the workplace.
• To be used to keep the correct distances indicated in the
installation diagram.
E.5 Positioning
The machine must be taken to the place of installation and the
packing base removed only when being installed.
Arranging the machine
• Wear protective gloves and unpack the machine.
• Lift the equipment with a lift truck, remove the base and
position it the place of use.
