PREFACE
This manual gives instruction for the proper use of the machine. Keep it near the machine in place that
is known to all users. The manual is essential for safety.
This machine is an automatic packaging machine designed to package a single item, or a group of items
using center-folded shrink film. A few examples of products packaged are: food items, housewares, and
toys. This machine can be operated in two modes, it can be fed manually by a qualified technician, or it
can be in series with other machines in automatic mode. In automatic mode the machine is controlled
by logic in its PLC.

SAFETY STANDSARDS
DESCRIPTION OF SAFETY STICKERS:
 On machine front panel.
Danger of electrocution!
Risk due to presence of electrical power in electrical system inside panel.
When the panel is opened, the machine must be switched off and the plug must be pulled from the socket
of the main circuit.
While the machine is running, the panel must be mounted properly.
 On the sealing bar frame.
 At the shrink tunnel infeed and outfeed.
ATTENTION! Hot members. It shows the danger of burning, thus involving the risk of a serious
accident for the exposed person.
 At the conveyor belt infeed and outfeed.
Dragging hazard!
Hazard generated by moving elements (conveyor belts, motor driven rollers) in the event of contact during
operation phases.
 In the product loading area on the infeed belt.
Wear safety shoes that protect feet from impacts, crushing and compression while moving or handling the
machine.
Wear safety gloves that protect the hands from crushing and mechanical hazards and while moving or
handling the machine.
Wear safety gloves that protect the hands against the specific risks associated with the materials to be
packed (mechanical, chemical) and against coming into contact with the high temperatures present on the
seals and/or sealing blade (up to 200°C).
Wear safety gloves that prevent the hands from coming into contact with foodstuffs when
packaging them.

SAFETY STANDARDS
The machine is equipped with 2 front guard doors (C1) and (C2).
If one of the doors is opened, the machine stops and the “alarms” button on the display becomes red.
To reset machine operation, close the door and press the RESET (S2) button. The “alarms” button be-
comes green.
There are also 2 emergency stop buttons, see page 10.

7
SAFETY STANDARDS
Comply with the following prohibitions and warnings.
Dragging hazard!
Hazard generated by moving elements (conveyor belts, motor driven rollers) in the event of contact during
operation phases.
Burn hazard!
 Risk due to high temperature of the sealing bar.
Do not touch the bar.
 Risk due to high temperature inside the shrink tunnel.
Do not place your hands inside the tunnel.
Before performing operations in these zones, set the machine to “maintenance mode”, and wait for heaters
to cool.
Electric shock hazard!
Electric control board: risk due to electric energy inside electrical control board (upstream from the main
switch).
Before performing maintenance:
 switch the machine off by rotating the main switch (Q1) to “0” (OFF)
 remove the plug from the mains socket
 WAIT 15 minutes to allow the capacitors to discharge.
The casters must be used only for moving the unit short distances across smooth, level floors.
Make sure the film roll is properly seated in its place.
Danger of placing hands inside!
Danger caused by placing hands in the product loading area on the infeed belt.

MACHINE INSTALLATION
Environmental conditions
Place the machine level on the floor in a suitable environment free from humidity, gases, explosives, combustible materials. The
machine may only be installed on smooth, flat non-inflammable surfaces.
Working environment conditions:
Temperature from + 5°C to + 40°C (41 to 104°F)
Relative humidity from 30% to 90%, without condensation.
The lighting of the operation room shall comply with the laws in force in the country where the machine is installed. However, it shall
be uniform and allow good visibility in order to safeguard the operator’s safety and health.
MACHINE PROTECTION FACTOR = IP20
THE AIRBORNE NOISE MADE BY THE MACHINE IS LOWER THAN 70 dB(A)
Electrical connections
Voltage (V): see data on plate
Frequency (Hz): see data on plate
Maximum absorbed power (W): see data on plate
Maximum absorbed current (A): see data on plate
Note: when contacting the Manufacturer, always indicate the model and the serial number
specified on the plate on the rear part of the machine.
The power line must be protected with a type B residual current device with rated residual current equal to
“IΔn”, 30 mA.
As a result, the maximum resistance of the earth electrode must correspond to the values indicated in the
following table
IΔnMaximum resistance of the earth electrode

OBSERVE HEALTH AND SAFETY REGULATIONS!
If the machine is not equipped with the power supply plug, use a plug that is suitable for the
voltage and amperage values described by the rating plate and that can comply with the
rules in force in the installation country.
GROUNDING OF THE UNIT IS OBLIGATORY!
Before executing electrical connections, make sure the mains voltage matches the one on
the plate on machine rear and that the ground contact complies with the safety rules in force.
In case of doubts about the mains voltage, contact the local public supply Company.
Insert the plug on the cable from machine electrical cabinet in a mains power supply socket
that can be reached easily by the operator.
