Models with filter - 9714 NF - 9712 NF - 9709 NF – 9709 NELF
The external filter is essential to avoid liquids or powder can damage the internal circuit of the machine. Liquids and powder stops in the filter cover. To
clean the filter unscrew by hand the cover and clean. Pay attention in screws the cover as the gasket must be correctly placed to avoid problems in
machine functioning. Filter could affect the speed of suction, causing the machine to be a little slower than normal.
END OF OPERATION
At the end of vacuum/welding operation unplug the machine.
VACUUM LEVEL
The vacuum gauge is provided with 3 differently colored areas showing the vacuum level. The yellow area corresponds to
operation start, when the air quantity in the circuit is still high. In the green area the vacuum level is already sufficient for a
correct food preservation for a short or medium time, when the indicator lies between the two black lines. When the indicator
reaches the red area, the maximum vacuum level has been obtained.
There are also products (such as fish, tomatoes, etc.) containing liquids which, in case of compression, leak out and can be
sucked by the machine with resulting damages to the same. Other products are not very compact and an excessive vacuum
level can damage or crush them. We recommend to check the adherence of the bag and weld before the product is crushed.
MAINTENANCE AND CLEANING
Disconnect the plug from the socket before cleaning or maintenance. In such a way that an
operator located near the machine can check that the plug remains removed.
Do not use water splash for cleaning. Do not use brushes that can deteriorate the surface of
the machine.
Use a soft cloth moistened with normal neutral detergent to avoid deteriorate the surface of
the machine.
Do not wash the machine and do not put in water or liquids to clean. Contact immediately the
supplier in case of malfunctioning or damaged parts.
QUESTIONS / ANSWERS
In case of doubts about the correct functioning of the appliance, some test can be done by the user to verify the performances of the machine.
Internal functioning:
1-
Open the cover (4) and start the cycle once introduced the adapter hose into the air suction plugs (8) (Image 6) and lock the adapter on a plane
surface to make vacuum.
2-
If the manometer arrives on red and the seal starts automatically, the machine is OK.
3-
If the manometer arrives on red but the seal do not start automatically, set the unit on automatic cycle and re-test. 4-
does not arrive on red, the machine must be repaired (air loss or pump damaged).
Cover and vacuum gasket functioning:
1-
Close the cover (4) (without bag) and press pump switch (1) to start the cycle, slightly press with both hands the cover. (Image 7) 2-
If the manometer arrives on red and the seal starts automatically, the machine is OK.
3-
If the manometer arrives on red but the seal does not start automatically, set the unit to automatic cycle and re-test; 4-
If the manometer does not arrive on red, check the vacuum chamber gasket, clean or replace and re-test;
Bag test:
1-
Open the cover (4)
2-
Place the open side of an empty vacuum bag in the vacuum chamber (6), between the gaskets (5). (Image 1) 3-
Close the cover and press pump switch (1). This will start vacuum operation.
4-
As soon as vacuum pump starting, slightly press with both hands the cover so as it sticks to the surface of the bag. After a few seconds the
depression created by the pump will permit to release the cover, while the machine will keep on suction.
5-
If the manometer arrives on red and the welding starts automatically, the machine is OK.
6-
If the manometer arrives on red but the seal does not start automatically, set the unit on automatic cycle and re-test.
With the above 3 tests you can check the correct functioning of the appliance and the correct placing of the bag in the vacuum chamber.
The unit does not start:
1-
Check if the IEC plug is well connected.
2-
Check if the power switch (11) is on (green light on).
3-
Check the fuse in the IEC socket on the rear part of the machine and change it, if necessary, with the spare fuse you find in the IEC of the
machine.
The bag is not well sealed / Air come in the bag:
1-
In winter season, the sealing bar can be charged in humidity, at first use start a complete vacuum/seal cycle with cover closed and no bag. To
avoid problems, the unit must be stored in a dry and no dust place at +10°-+30°.
2-
Bags outside is in nylon (PA), nylon is a hygroscopic material, to avoid seal problems due to humidity, store bags in a dry and no dust place at
+10°-+30°.
To have a correct seal, use the potentiometer as per explicated above in "The Potentiometer" paragraph.
3-
4-
You can have a good vacuum only if there is enough empty free space between the food and the machine to avoid the creation of wrinkles and
folds, which may reduce the vacuum reached inside the bag. Without wrinkles and folds you can have a correct cover closing and the
If
