3. Close the lid and will hear the pump start up. Press down firmly across the width of the lid to
initiate the vacuum.
4. When the pressure gauge (N) reaches -0.90 bar then 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 low pressure then you may need to
press down very hard
on the lid of the machine
during the sealing process, to achieve a good seal.
Manual Operation
Use this when the item you are packing is fairly soft or contains too much liquid for automatic
operation. See Packing at a Lower Pressure.
1. Set the vacuum pump control switch (R) to ‘II’
2. Set the manual/auto switch (S) to ‘MAN’.
3. Set the rotary switch which controls the bag sealing time (L) to 5.
4. Place the item in the bag and place the bag with the rough/embossed side down. Lift the front
of the machine and place the top of the bag into the bag locator (F). It is vital that the top of the
bag is correctly located with the full width of the bag
inside
the bag locator. Failure to locate the
bag properly is the most common cause of problems with Lava machines.
5. Close the lid and you will hear the pump start up. You must then
press down firmly
on the
corners of the lid. Failure to press down hard enough at this stage is the second most common
cause of problems with Lava machines.
6. When the desired pressure is reached, firmly 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 bag is
now sealed.
7. Set the vacuum switch (R) to ‘0’.
8. You can now raise the lid and remove the sealed bag. Before packing other items, check that the
seals look OK – see Checking the Seal.
Checking the Seal
The seal should be a clear line running uninterrupted the full width of the bag. If the bag is melted
through then you will need to turn the rotary switch (L) down a little. If the seal is interrupted then you
will need to turn it up. Once this has been correctly set for the type of bag you are using, you should
not need to alter it.
Please note that if you are packing at a low pressure then you may need to
press down very hard
on
the lid of the machine during the sealing process to achieve a good seal. This process is not required on
Premium
models.
