Packing at a Lower Pressure
When the item you are packing is fairly soft or contains too much liquid to be packed at 0.9 bar then
you will need to pack at a lower negative pressure. You will need to experiment to find the
optimum setting. This can be done as follows:
1.
Set the vacuum pump control switch (R) to ‘II’
2.
Set the manual/auto switch (S) to ‘MAN’.
3.
Close the lid and you will hear the pump start up. Press down firmly on the corners of the lid
to initiate the vacuum.
4.
When the pressure gauge (N) reaches 0.9 bar, gently unscrew the pressure release valve on
the top of the liquid trap (E). As you unscrew the pressure release valve you will see the
pressure fall. Use the pressure release valve to set the pressure to the desired setting.
5.
When the desired pressure is reached, set the vacuum pump control switch (R) to ‘0’.
You can now pack at this lower pressure as detailed in Manual Operation. Please note that if you
are packing at a very low pressure then you may need to press down very hard on the lid of the
machine during the sealing process.
Emptying the Liquid Trap
The Lava range of vacuum packing machines have been equipped with a liquid trap (E). If at any
time liquid of any sort enters this trap please stop the machine immediately. The liquid trap is
designed to stop liquids from entering the vacuum pumps and damaging components beyond repair.
This important facility is not found on other inferior makes and distinguishes the Lava machines
from other competitors.
To empty the liquid trap, switch the machine off, remove the lid of the liquid trap and dry out the
inside of the trap using a paper towel or similar. You can then replace the lid.
Using Continuous Rolls
Continuous rolls give you a lot of flexibility when packing and keep wastage to a minimum. These
must be cut to length and one end heat sealed before use. You will need to allow an extra inch or so
for the first/bottom seal (which you should make with nothing in the bag) and about three inches for
the top seal. The quickest way to make the first/bottom seal is as follows:
1.
Set the vacuum pump control switch (R) to “II”.
2.
Place the end of the roll in the machine. You do not need to place the end of the roll into the
locator strip, just place it over the Teflon heating strip.
3.
Close the lid and press down firmly.
4.
Depress and hold switch (P). The red sealing indicator light (M) will come on. When the
light goes out you can release the switch. The roll is now sealed.
5.
Set the vacuum pump control switch (R) to “0”.
6.
You can now raise the lid and remove the sealed roll. See Checking the Seal.
