Basically you can use almost any foil for external vacuum sealer up to 200 microns thickness with a LAVA.

  • Check the bag, whether it was placed inside the unit below the stop bar. The vacuum bag must be placed neatly and shall not have bumps.
  • Do you use structured vacuum bags or smooth vacuum bags? If you use smooth vacuum bags you must ensure that they are at least 120 microns thick and be placed specifically into the device. How this will be done will be explained in: Vacuuming of smooth sachets.
  • In rare cases it can happen that that you need to press a little bit stronger, when using a new unit. Push down the device door. This is neccessary to the vacuum can be generated. The reason for the increased pressures at the beginning is at the seals.
  • The pressure regulation L+ (accessory) is open too wide; close them that the device can create a vacuum.
  • Remove the rectangular sponge rubber gasket at the bottom of the device and in the device door. Clean and dry them and install them again.

First, cut with scissors to desired foil-length from the roll. Now, one side will be welded. Please note that the foil will be layed only on the welding tape and not up to the stop bar. Do the welding easily in the automatic mode. The pump will start because the device needs to generate a vacuum to make a clean weld. Now, if one side is welded, fill the vacuum bag and vacuum it.

  • The sealing bar is dirty. Unplug the device and clean the sealing bar with a damp cloth.
  • Welding band tape is worn out. Order a new welding band tape in the Lava online shop and install it to your device.
  • When vacuuming rolls only put the vacuum bag to the welding tape when welding and not up to the stop bar. Once the suture was made, turn the bag and the vacuum as normal.

Liquids can be vacuumed in small quantities without any problems. It is always advisable to have a Lava vacuum sealer with a 2- or 3-welding for this use cases. In larger amounts, for example, soups, sauces and stews Lava recommends only vacuum containers.

The suction device (attachment) which is necessary comes with your Lava by default.

The Lava new-line vacuum lid and cases were tested by the institute Fresenius, and held about 25 days long tight, which is on a short-term storage a lot. Generally, we recommend for cases and lids always a short-term storage with max. 10 days. Please check that the following points were taken into account:

  • Please remove the valve and wash out completely, that it is always residue.
  • The seals must be completely clean, without residues.
  • The vessel, which is vacuumed must have a broad, smooth edge.
  • The suction device always remove the device and NOT on the valve cover.
