Vakuum Packing in Bags
Place the machine on a flat level work surface. You will need to allow enough space in front of the
machine to lay the bag flat and you may find it easier to place a one inch high cutting board or
something similar underneath the bag to keep it as flat as possible.
Plug-in the machine and switch it on using switch (C). The switch should light-up red. If not then check
both the power supply and fuse.
You should choose a bag that is the correct size. Allow an inch or so on either side of the item you want
to pack and at least 2-3 inches at the top of the bag.
Decide whether you are going to use automatic or manual operation. If you use automatic operation
then the item will be packed at a pressure of about -0.90 bar. This is enough negative pressure to crush
a Coke can and it can squeeze the liquid out of soft food items and this liquid may then be drawn into
the liquid trap. It may also force food items out of shape which may be important if they are being
displayed for sale. See Packing at a Lower Pressure. Another option is to instigate the sealing process
before maximum pressure is reached. You can do this by pressing the red button (P) at any time during
the vacuum extraction process. The machine will then automatically complete its cycle.
Automatic Operation
Use this when the item you are packing is fairly resilient and does not contain too much liquid. You may
need to experiment to discover which items are suitable. Also remember you can instigate the sealing
process by pressing the red button (P) at any time if you see liquid begining to rise up the bag.
1. Set the vacuum pump control switch (R) to ‘II’
2. Set the manual/auto switch (S) to ‘AUT’.
3. Set the rotary switch which controls the bag sealing time (L) to 5.
