WARNING: THE USE OF THE ONLY WELDING AND SOFT VACUUM FUNCTIONS DOES NOT INCREASE THE TIME OF
CONSERVATION OF FOOD IN A SIGNIFICANT WAY, AS THE AIR QUANTITY EXTRACTED FROM THE BAG IS VERY MODEST.
TROUBLESHOOTING
The machine does not start:
1- Check that you have correctly inserted the plug in the socket and that the socket is powered.
2- If pressing a button the three leds light up and flash simultaneously, the machine is in the thermal protection phase, it is necessary to wait
for the cooling time (30 seconds from the end of the previous vacuum or welding cycle).
The bag is not well welded / air enters the bag:
1- In the winter season, and in the presence of strong temperature changes, the sealing bar can be charged with humidity. On first use with
cold machine it is advisable to carry out a complete vacuum/welding cycle with the lid closed (even without a bag) to reset the machine and
stabilizing the temperature and humidity conditions. To avoid problems even at first use,
the appliance must be stored in a dry place at
temperatures b 10° and + 30°.
2- The bags are manufactured with an outer layer of nylon for protection against the entry of air; nylon tends to absorb humidity especially in
the presence of temperature changes; the absorbed humidity prevents the correct welding: to avoid this problem,
the bags must be stored
in a dry place at temperatures b 10° and + 30°.
3- The moisture absorbed by the outer layer of the bag can be eliminated by welding the bag twice.
4- Check that you have left enough free space between the product to be packaged and the opening of the bag; limited space creates
wrinkles and folds that prevent correct welding and limit the level of vacuum that can be reached.
5- Check that you have cleaned the bag opening near the welding point; any impurities deriving from the passage of the product to be
packaged prevent proper welding.
6- Check that you have removed all the possible roughness that can pierce the bag; the machines create a high vacuum level with
consequent adhesion of the bag to the product, any point or unevenness can create micro holes in the bag that will let air in.
7- Moist products can make liquids rise towards the opening of the bag damaging the weld; check that you have dried the products to be
packaged or use a double bag; insert the product in a first bag, fold the opening of the bag several times and insert it in a second bag with
the opening of the first one turned towards the bottom of the second. The vacuum function will be able to be performed and any residual
liquids will remain in the first bag without passing to the second, thus obtaining an effective weld. Alternatively, if you want to seal a liquid
product even without obtaining a vacuum level suitable for storage, we recommend using the Soft Vacuum function.
8- If air enters the bag after a correct vacuum/welding cycle, the bag that is probably damaged must be replaced.
The machine does not make the vacuum in the bag:
1- Check that you have correctly positioned the opening of the bag between the gaskets in the vacuum chamber.
2- The machine works correctly with embossed bags with a thickness of 90 to 105 microns, different bags may not work properly; check that
you have used the correct bags and in any case embossed bags (not completely smooth).
3- Check the vacuum chamber gaskets; in case of modest aspirations of liquids the gaskets can harden and be damaged; in this case it is
necessary to change the gaskets.
The machine does not weld automatically:
1- Start a vacuum cycle and weld manually to check that the sealing bar is working properly.
2- Check that you have left enough free space between the product to be packaged and the opening of the bag; a limited space creates
wrinkles and folds on the opening of the bag which limit the level of vacuum that can be reached and prevent the vacuum sensor from
starting the welding automatically.
The machine does not reach a convenient vacuum level:
1-
Check that you have correctly positioned the opening of the bag between the gaskets in the vacuum chamber.
2-
The machine works correctly with embossed bags with a thickness of 90 to 105 microns, different bags may not work properly;
check that you have used the correct bags.
3-
Check that you have removed all the possible roughness that can pierce the bag; the machines create a high vacuum level with
consequent adhesion of the bag to the product, any point or unevenness can create micro holes in the bag that will let air in.
4-
Check that you have left enough free space between the product to be packaged and the opening of the bag; a limited space
creates wrinkles and folds on the opening of the bag that limit the level of vacuum that can be reached.
5-
Check the vacuum chamber gaskets; in case of modest aspiration of liquids the gaskets can harden and be damaged; in this case
it is necessary to change the gaskets.
6-
Make sure you have not pressed the Soft Vacuum button (2) instead of the button for the normal vacuum cycle (1); the Soft
Vacuum function creates a vacuum of about -200 mbar.
