Safety when vacuuming

DANGER
Generating vacuums kills live animals! Do not vacuum pack anything which is alive and ensure
that no live animals are vacuum packed by unauthorised personnel or children!
Vacuum packaging systems use a vacuum pump to remove air from a hermetically sealed vacuum
chamber in which the product and the packaging has been placed. Therefore, access is not possible
during the sealing process. External air has to flow into the chamber before it can be opened.
Never try to open the tool with force.
Never try to open the vacuum chamber with force!
The vacuum is used to extract the air in the packaging. According to the laws of thermophysics,
moisture in the air starts to evaporate at a relatively low vacuum. This means that products which
contain a large amount of uncombined moisture can be affected.
The vacuum pump has the reverse effect, like a compressor. Dust particles, but also moisture, are
entrained by the vacuum current and can reach the vacuum pump unhindered. If products for which this
process can occur are to be packaged, it is recommended to contact the machine manufacturer.
It is also hazardous to package flammable or explosive products (icing sugar or dextrose, but also spray
or perfume bottles), since entrained parts or particles can react accordingly.
WARNING
Risk of explosion! Spray bottles with a specified internal pressure should not be vacuum
packed, since a reduction of the external pressure causes the high internal pressure to explode.

Inert gas

The machines with the inert gas system (VC999 K12N, VC999 K12NA types) are intended to use the
following inert gases:
 nitrogen (N
 carbon dioxide (CO
 any mix of these two gases.
WARNING
Risk of fire or explosion! In the gas mix introduced, ratio of oxygen (O
NOTICE
Please contact your inert gas supplier to receive information about which inert gas
composition is suitable for your products!
WARNING
Risk of fire or explosion! When using a gas mixture with oxygen, it is imperative that fireproof
hoses are provided at the machine and by the customer for the inert gas supply.
