1.3 Intended use
The machine is a piece of technical equipment to be used exclusively
as a working appliance. The machine may only be operated by per-
sons older than 14 years of age.
Use the machine only to pack products in pre-made film pouches.
The film pouches are closed with a seal seam.
For specifications, see Technical specifications.
Any other use is considered improper and can endanger persons, the
product and the machine.
1.3.1 Electromagnetic compatibility (EMC)
The machine has been designed for use in residential, business and
industrial areas (without a separate power substation, it can be con-
nected directly to the public mains). Operation can be impaired when
used in an industrial environment.
1.3.2 Non-ionising radiation
The machine produces unintended non-ionising radiation. This is only
emitted by electrical operating equipment as a function of its inherent
technical nature. e.g. from electric motors, high voltage wires, mag-
netic coils. There are moreover no strong permanent magnets built
into the machine. Any effect on active implants can therefore be ex-
cluded with a high degree of probability as long as a safety distance
of 30 cm is maintained between the implant and the field source. Ac-
tive implants can be: heart pacemakers, defibrillators etc.
1.4 Reasonably foreseeable incorrect use
The following work methods are not in accordance with regulations
and therefore are prohibited:
• Operation in an atmosphere capable of explosion.
• Packing of highly flammable, combustible or explosion-prone
products.
• Packing of dust-forming or powder-forming material.
• Gas flushing of film pouches with explosive gas mixtures (e.g.
oxygen proportion over 21 %).

Safety
Reasonably foreseeable incorrect use
14 10.06.2014
• Use of the chamber lid and the viewing window in the chamber lid
as a storage, working or cutting surface.
• Cleaning of the chamber lid and the viewing window in the cham-
ber lid with cleaning agents which have an abrasive effect (e.g.
abrasive household liquid cleaner, scouring pads, steel wool etc).
• Aseptic packing of products.
Info
Misuse will exclude any liability on behalf of the manufacturer. In
such a case, the operating company alone bears the risk.
1.5 Warning against incorrect use
• Incorrect operation
For example: sealing times that are too short or too long and there-
fore result in improperly sealed packs which in turn damage the
product.
• Neglecting the following work tasks:
– Inspections.
– Cleaning work.
– Maintenance work.
• Use of third-party parts, i.e. parts that are not MULTIVAC spare
parts.
• Operation under prohibited ambient conditions.
1.6 Residual risks
The safety instructions in this manual serve as guidelines for trained
operating personnel in safe working practice with the machine. The
manufacturer cannot however foresee all possible product-related
hazards. This is why the safety instructions and warnings on the ma-
chine and in this manual cannot be considered exhaustive. The oper-
ating company and operating personnel remain ultimately responsible
for safety.
1.7 Obligations of the operating company
1.7.1 Creating the operating directive
The machine and operating materials are a potential source of haz-
ards. The operating company is obliged to draw up an operating di-
rective. The operating directive regulates the handling of hazardous
machines or operating materials, as well as laying down rules for be-
haviour in the case of an emergency. The required information can be
found in the following documents:
• The EC directives for worker protection.
• National legislation.
• Accident prevention regulations.

Safety
Obligations of the operating company
10.06.2014 15
• The machine instruction manual.
1.7.2 Monitoring obligation
The operating company is obliged to continuously monitor the condi-
tion of the entire machine, for example:
• Visible defects or damage.
• Changes in the operating behaviour.
• Age of the machine.
The operating company is obliged to ensure, that the machine is no
longer operated when it is older than 19 years. The correct function-
ing of the safety functions for the electronic components can no
longer be guaranteed after this age. The year of manufacture on the
type plate of the machine serves as the starting point for assessing
the age. In order to be able to operate the machine after this, the op-
erating company must commission the manufacturer to check the
safety functions of the machine.
Info
Do NOT start up the machine, if there are visible defects or if the
machine is older than 19 years.
1.7.3 Making the selection of personnel
The operating company has to choose the personnel according to the
tasks to be carried out, see Section 1.1.1 "TARGET GROUP". The oper-
ating company has to order and authorise the personnel for the tasks
to be carried out.
Info
Trainees or other persons receiving instructions may only operate
the unit under the constant supervision of an experienced techni-
cian.
1.7.4 Training the personnel
The operating company is responsible for ensuring, that the person-
nel is trained and instructed in accordance with the tasks, which have
been assigned to them. The following measures can for example con-
tribute to the training and instruction:
• Provide an operating directive, which is comprehensible to the
personnel.
• Instruct personnel on how to handle the machine correctly.
• Make the machine instruction manual accessible to the personnel.
If necessary, order an instruction manual from the manufacturer in
the appropriate official language.
• Inform the personnel about measures for avoiding hygiene risks.
• MULTIVAC offers appropriate training courses.

Safety
Obligations of the operating company
16 10.06.2014
1.7.5 Providing personal protective equipment
The operating company must ensure that the operators wear the re-
quired personal protective equipment (foot protection, head gear,
gloves, etc.) in accordance with the national directives which apply. In
Europe the directive 89/656/EEC specifies the minimum mandatory
requirements for the use of personal protective equipment.
1.7.6 Avoiding hazards
The operating company must check, whether there are special haz-
ards during operation, e.g. through hazardous fumes. The operating
company must undertake measures to avoid or limit the hazards.
1.7.7 Providing the installation location
The operating company is obliged to provide a suitable installation
location for the machine. The requirements for the installation location
can be obtained from the manufacturer.
1.7.8 Provide power supply
Connect the machine to the mains electricity at an always easily ac-
cessible place. In the case of an emergency the machine must be
capable of being disconnected immediately from the mains electricity.
The power supply must be equipped as follows:
• Overcurrent protective device according to IEC 60204-1: 2005.
• Mains power breaker according to IEC 60204-1: 2005.
Connection via residual
current protective
device
If the machine is to be operated via a residual current protective de-
vice, a residual current protective device which is sensitive to all types
of current should be used.
Info
In exceptional cases, the leakage current can be so high that an
isolating transformer needs to be installed between the power sup-
ply and the machine.
Connection to IT
network
The machine cannot be connected directly to an IT network.
The IT network must be converted to a TN-S network by an isolating
transformer. The machine is connected to the TN-S network.

Safety
Obligations of the operating company

fitting of an overpressure valve.
• The pressure relief capacity of the safety valve must be dimen-
sioned for the maximum possible throughput of the pressure re-
ducer.
• In the case of a release of pressure, the gas must be diverted to
non-hazardous areas.

1.7.10 Avoiding hygiene risks
A high standard of hygiene is achieved through design, choice of ma-
terials and workmanship.
It is imperative that this high level of hygiene be maintained by every
operating company. Particularly where food or sterile medical prod-
ucts are being packed, the currently valid hygiene standards must be
strictly observed. The person charged by the operating company with
safety and/or hygiene must clarify, which regulations apply to the
product to be packed, and the person must then implement these
regulations.
The manufacturer assumes no liability whatsoever for any warranty
claims and damage claims of any kind resulting from insufficient hy-
giene and insufficient cleaning.
WARNING
Health hazard!
Insufficient or sporadic cleaning can promote the growth of micro-
organisms which can change unfavourably the product that is to be
packed.
This can severely damage the health of people, especially of the
consumers.
Among other measures the following are definitely required:
¾Create a company cleaning guideline.
¾Perform cleaning regularly.
¾Check the effectiveness of cleaning procedures on a regular
basis.
¾Follow instructions in the chapter 'Cleaning'.
1.7.11 Checking the packs
CAUTION
Health hazard!
Faulty or damaged packs (reject packs) can have far-reaching con-
sequences, for example, spoiled products.
Spoiled products can pose a health hazard.
¾Check packs on a regular basis during running operation.
¾Do NOT put faulty or damaged packs (reject packs) into circula-
tion.
Info
It is the operating company's duty to determine the overall testing
procedure.
Testing procedure
Depending on the film pouch and the demands placed on the packs,
various types of testing procedures are available, e.g.:
• Check seal seam width.
• Visual inspection: Asses the pack optically.

Safety
Obligations of the operating company

• Storage test: Store a good pack for a defined period and then re-
inspect.
• Stacking test: Stack good packs on top of each other for a defined
period and then re-inspect.
• Check the seal seam strength with a tensile testing machine.
• Low-pressure test (for vacuum packs).
• Measurement residual oxygen (for gas-flushed packs).
The following faults can result in a pack not being airtight:
• A leaky seal seam. Possible reasons:
– The inside of the packaging material is contaminated by product
in the seal seam area.
– The sealing time is too short.
• Damage to the pack caused e.g. by sharp-edged products.
Time of inspection
• After machine start-up.
• When a defined time interval was reached during running opera-
tion.
• When the pack size was changed.
• When other types of films or other film thicknesses are being used.
• When spare parts or wearing parts were built in.
• After faults to the machine were eliminated.
• After changes to the machine settings.
1.7.12 Pump protection function
The vacuum pump in the machine runs for a set time when the
chamber lid has been closed. During this time any undesired liquid in
the oil of the vacuum pump evaporates. This increases the lifespan of
the vacuum pump. When packaging moist or liquid products, the op-
erating company is obliged to perform this function at least once a
day at the end of a working day. The manufacturer assumes no liabil-
ity whatsoever for any warranty claims and damage claims of any
kind that result from the insufficient performance of this function.
NOTICE Danger of material damage!
Penetration by foreign matter (e.g. liquids, product residue, foreign
bodies) will damage the vacuum pump.
Damage can cause faults in the machine, which in turn can result in
reject packs.
¾Cancel the evacuation process immediately if foreign matter is
sucked in.
¾Change the oil in the vacuum pump.

WARNING
Injury hazard!
Altered, damaged, defective or incorrectly applied or missing safety
devices will render the danger zones unprotected.
Unprotected danger zones can cause serious or even fatal injuries.
¾Do NOT alter the safety devices.
¾Use only MULTIVAC spare parts and accessories.
Before switching on the machine each time:
¾Check that all safety guards close completely and prevent
reaching into the danger zones.
¾Check that only those safety devices are used which are suit-
able for the machine equipment.
¾Check that all safety devices are functional and in a technically
flawless condition.
