wrinkles, otherwise the seal may not be complete. If you need to interrupt the vacuum operation for any reason first press the “Stop” Button. It is then safe to unlock the cover. PLEASE NOTE ► Do not overstuff the bag; leave enough empty length in the open end of the bag (at least a few inches) so that the bag can be properly placed in the vacuum chamber. ► Do not wet the open end of the bag. Wet bags may not seal properly. ► Clean and straighten the open end of the bag before sealing. Foreign matter or creases on the bag may result in a faulty seal. ► Press the bag to expel excess air before vacuuming it. Too much air inside the bag may result in a poor vacuum. ► If the food you’re sealing has sharp edges (such as bones or shells) pack the edges with kitchen paper to avoid tearing the bag ► We suggest you allow one minute of time in between sealing sessions to allow the sealer to cool. ► When vacuum sealing liquid-based foods (such as soups or stew) freeze them first in a baking pan or tempered dish before bagging and vacuum sealing them. ► Blanch vegetables by cooking them briefly in boiling water. Allow them to cool then vacuum seal them in convenient portions. ► When vacuum sealing unfrozen food, allow at least two additional inches of bag length for expansion while freezing. Place unfrozen meat or fish on a paper towel and vacuum seal with the paper towel in the bag to absorb any extra moisture. ► Before storing foods such as tortillas, crepes or bread, use wax or parchment paper between them to stack the pieces. This will make it easier to remove an individual piece, reseal the rest and immediately replace them in the freezer.caso VC320 Pro 45

15.8 Use of the function "Adjustable vacuum strength"

Since the pressure of the vacuuming becomes too strong for specific foods and these could be crushed in the bag, you can adjust the length and strength of the vacuuming process via the function "Adjustable Vacuum strength". So you can adjust the vacuum strength to the consistency of your vacuum food and also seal soft foods (for example berry fruit) without crushing them. Due to the time and pressure control, the crushing of delicate foods is prevented. You can also use this function for the packaging of juicy foods to prevent that fluids are aspirated and drawn out. Adjustable Vacuum strength

7. Put the foods you want to store into the bag.

8. Clean and smooth the open end of the bag and be sure that there are no folds or

waves on the surfaces of the open ends.

9. Be sure that the open end of the bag is within the vacuum chamber seal. This

guarantees that there is no escape of the vacuum.caso VC320 Pro 47

12. Then press the button "Schweißen" and seal the bag.

** Press the button “Stop” to interrupt the process.

15.9 Use of the function "selectable welding time"

When there are fluids in the bag and hence in the section where you want to seal it, the welding procedure should be adjusted to "feucht". This would increase the welding time and the bag is safely sealed. Press the button "Trocken & Feucht". If the lamp will illuminate above "feucht", the welding time for moist vacuum food is adjusted. Please note ► Do not put too much food inside the bag; leave enough empty length in the open end of the bag so that the bag can be placed in the vacuuming plate more positively. ► Do not wet the open end of the bag. Wet bags may be difficult to seal tightly. ► Clean and straighten the open end of the bag before sealing the bag. Make sure nothing is leaving on the open area of the bag. Foreign objects or creased bags may cause difficulty to seal tightly. ► Do not leave too much air inside the bag. Press the bag to allow extra air to escape from the bag before vacuuming it. Too much air inside the bag increases the vacuum pump loading and may cause that the motor works insufficient to draw away all the air out of the bag. ► If the foods you’re sealing have sharp edges, such as bones, spaghetti or shellfish, pack the edges with kitchen paper to avoid tearing the bag ► Suggest to vacuum seal one bag within 1 minute to let the appliance cool down enough. ► In order to vacuum seal liquid-based foods, such as soups, casseroles or stew, freeze them first in a baking pan or tempered dish, vacuum seal them, label and stack them in your freezer as soon as they are in frozen solid. ► Blanch the vegetables by cooking briefly in boiling water or microwave oven, cool them down , then vacuum seal them in convenient portions. ► To vacuum seal the foods not frozen, two extra inches are required for bag length to allow for expansion while freezing. Place the meat or fish on a paper towel and vacuum seal with the paper towel in the bag, this way will help to absorb moisture from the foods. ► Before storing the foods such as tortillas, crepes or hamburger, use wax or parchment paper between them to stack the pieces, this will be easier to remove some of the food, reseal the rest and immediately replace in the freezer. ► The vacuum sealer can’t be used directly for vacuum sealing canisters or canning jars.caso VC320 Pro 48

15.10 Opening a sealed bag
