Use
Proper use
This machine is a technical work tool designed to be used exclusively for
work.
It is to be used solely for packing products in pre-manufactured film
pouches which are closed with a seal seam.
For specifications, see the section "Technical data".
Any different or further application is not considered appropriate use and
can pose a hazard to persons, products and the machine.
Inappropriate use (misuse)
This machine is not suitable for the following:
– Aseptic packaging of products.
– Operation in rooms where there is the risk of explosions occurring.
–Gas flushing film pouches with gas mixtures containing more than 21%
oxygen.
Misuse excludes the manufacturer from any liability! The risk is
borne by the plant operator alone.
Avoidable incorrect use
– Use of externally purchased articles, e.g. non-original MULTIVAC
spare parts.
– Incorrect operation. Example: Sealing times that are too short or too
long result in the film pouches not being closed securely and thus
damage the product.
– Neglect of the required inspections, cleaning or servicing work.
Residual risks
The safety instructions in this manual are intended as work safety
guidelines for qualified machine operators. MULTIVAC cannot however
foresee all situations in which a hazard can arise. The machine safety
instructions and warnings in this operating manual can therefore not be
considered all-embracing. The plant operator and machine operator
remain responsible for safety.

Safety
Betriebsanleitung 07.06.2005 8/43
ba_c500_50s2GB06.fm ega
Electromagnetic Com-
patibility (EMC) Chamber machines are designed for use in domestic, business and trade
sectors (without the use of an individual transformer, running from the pub-
lic electric power supply). If employed in the industrial sector, a limitation of
the operating characteristics may occur. In comparison to employment in
the domestic, business and trade sectors it is therefore possible that the
quality of operation may additionally suffer.
Operation with inert
gas
For machine with an inert gas system, the packs can be gas flushed after
evacuation.
Which inert gasses are used?
The inert gasses nitrogen (N2) and carbon dioxide (CO2) are components
of the natural atmosphere. They are recognised as harmless. They re-
place the previously removed air in the packs. Therefore one speaks of an
exchanged atmosphere.
Risk of explosions!
Aeration with O2> 21 % is not permitted!
This warning sign is located near the gas
connection:
Do not use inflammable gas.
Danger of suffocation!
Inert gas is odourless!
Ventilate rooms well, do not allow pockets of gas to form!
Observe national safety regulations concerning its use.
The initial pressure must not exceed 3.
Shut off the gas supply after completing work.

Set-up
– Note the weight of the machine, see "Technical data".
– Use suitable lifting equipment or have somebody else to assist you.
– Unpack the machine.
– Check there has been no damage caused during transport.
– Fill the vacuum pump with the oil (can) supplied.
– Check the oil level with the inspection glass.
Correct oil level between min. and max.
–After the oil has been poured in, the machine may only be levelly trans-
ported; the maximum gradient is 15°.
There are air de-oiling elements in the vacuum pump.
At an increased gradient the oil will move into the vacuum pump. Pos-
sible consequences:
– Air de-oiling components are wetted with oil and therefore become
unserviceable; this can be recognized by the presence of a strong
oil mist.
– The vacuum pump will be damaged.

Electrical Connection
– Read the nominal voltage from the nameplate. Does it conform to the
power supply voltage?
If the rotational directon is incorrect, the vacuum pump can be destroyed,
so:
– switch it off immediately!
– reverse the 2 phases of the supply line (only by a qualified electrician).
– Check the rotational direction of the vacuum pump.

Cooling water
connection (optional) Note on cooling water connection
When equipped with: Water cooling system
Water infeed
(infeed pressure max. 6 bar)
Water drain
Use a 1/2" water supply line for new installations.
Blow out supply line thoroughly before putting into operation.
The water drain should run downwards so that no remaining water can
flow backwards.
If water costs are high, return cooling in a closed water circuit can be more
economical. This also limits calcium deposits.
Cooling water requirements
– Input temperature max. 15 °C
– Filter element 50 µm
– pH value 6–7
– Concentration of:
Iron (Fe) and manganese (Mn) < 0.1 mg/l
Calcium (Ca) 22–50 mg/l
Magnesium (Mg) 13–30 mg/l
Free chlorine (Cl) < 0,1 mg/l

The appropriate water supply bureau makes the specifications.
If prepared (demineralised) water is used in a circuit, check the pH value
regularly.
If the pH value is in the alkaline range, i.e greater than 7.5, it is necessary
to add citric acid, for example, or elsealuminium hydroxid Al(OH)3will
form.
This leads to deposits and, in the worst case, blockage of the water line.
The ideal pH value is between 6 and 7. When installing a return cooling cir-
cuit, please consult MULTIVAC or its representatives.
Cooling water requirements
– For water pressure:
1 bar --> approx. 0.125 l / cycle
2 bar --> approx. 0.175 l / cycle
3 bar --> approx. 0.225 l / cycle
At 2 cycles / min., water consumption is at least 0.25 l / min.
– Recommended water pressure in the supply line:
min. 1,5 bar
max. 6,0 bar

Pressurised air
connection
For special cases, e.g. when packaging hot liquids or with high pressure
gas flushing of the packaging, a compressed air connection is installed to
increase the sealing force (see Fig.).
Without compressed air connection:
Sufficient sealing force is only obtained with a final pressure of under 400
mbar. Do not set a value higher than this.
– Use a pressurised air hose with an internal diameter of 8 mm.
Max. hose length: 5 m.
– Initial pressure at pressurised air connection: max. 6 bar.
– Set if necessary.
To do this:
– Open control cabinet doors on the machine.
– Pressure reducer is accessible.
– Set on pressure reducer (A): max. 1.5 bar.
– This increases sealing force.

Operation
Packing – First steps Start up
– Press I/O button.
– The LED (light-emitting diode) lights up.
–Machine is ready for operation. The digital display shows current air
pressure, e.g. 931 mbar. LED "mbar" lights up.
Note: Values over 999 mbar cannot be displayed.
There are 2 possible ways to evacuate:
Function "Auto":
The machine goes automatically into the "Auto" mode from evacuate to
sealing when the lowest possible residual pressure is reached in the pack.
The "Auto" function is stored ex works in the program P 1.
Function "Evacuation using prescribed settings":
If the prescribed pressure setting cannot be reached because of the prod-
uct (warm and moist product), and there is no further drop in pressure, the
vacuum pump switches off after 1 minute, without sealing the pouch. In
this case, increase the pressure value and repeat the packing process.

Loading the Factory Settings
– Press the P 1 button, P 1 appears in the digital display, the LED lights
up the button.
– Program P 1 is activated.
– Function "AUTO" is activated.
Note
–The factory settings are usage values. In some situations, it may prove
necessary to adapt these values to suit the product to be packed and/
or the pouch used.
Determine the correct settings by experimentation, see "Setting
recommendations" and "Displaying values, changing values".
– If the factory settings have to be changed and newly stored on
Program 1, please contact MULTIVAC.
Recommended Settings
Sealing
The standard pouch "PA/PE", thickness 100 µm, is best suited for most
gastronomic products.
Sealing time is approx. 1,4 Seconds.
The correct setting ensures:
Excess pouch film can be easily detached. It does not, however, fall off by
itself. The wide sealing seam is transparent and secure. It cannot be torn
open by hand.
Pressure
If possible, the product should be cool. Do not pack hot products unless
necessary (see also VACUUM QUICKSTOP button).
Rule of thumb:
The cooler and drier a product is, the less the residual pressure of the
pack.
A low value means that there is little air in the pouch. The lower the
pressure, the better the vacuum.
Examples:
– Product temperature under 7 °C
– Max. range of residual pressure approx. 10 mbar
– Product temperature approx. 40 °C
– Max. range of residual pressure approx. 65 mbar

To Be Noted When Using Liquid Products:
Vacuum lowers the boiling point of liquids. Liquids boil at a lower tempera-
ture under a vacuum, which makes itself noticeable through the formation
of bubbles in the pouch.
Immediately:
– Press the VACUUM QUICKSTOP button.
– Evacuation is stopped immediately.
– The pouch will be sealed.

Press REDUCE VALUE button until "Auto" appears.
– Start Evacuation.
– Observe the time at which bubbles form.
– Press VACUUM QUICKSTOP button.
– Note displayed pressure value, raise this by 10 mbar and input as set-
ting.
–Start evacuation again. Bubble formation should not occur any more. If
this is not the case, raise the pressure value slightly.
–By inputting a pressure value, the "Auto" setting is switched off. Dur-
ing following evacuation processes the evacuation will be stopped
before bubble formation occurs in the pouch.
Choice of Pouch, Filling It with the Product
– Choose an appropriate pouch size, avoid using an over-sized pouch.
The correct pouch ensures:
– low material costs,
– low waste,
– good appearance,
– long shelf life.
– Fill the pouch with the product.
– Clean the sealing seam of excess product.
Otherwise the sealing quality will be affected.

Putting the Filler Plates and Filled Pouches in the Chamber
The filler plates should reduce the volume of the chamber which is to be
evacuated and correctly position the pouch on the sealing bar.
The pouch collar should lie at about mid-height of the pouch level. Thus
folds in the sealing seam can be avoided.
– Establish the correct support height using the filler plates.
– Lay the pouch collar fold-free over the sealing bar.
Pouch collar must project over the sealing bar by approx. 2–3 cm.
Pouch collar must not protrude from the chamber, otherwise the
pouch will not be evacuated.
