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)
Place the open side of an empty vacuum bag in the vacuum chamber (6), between the gaskets (5).
2-
Close the cover and press pump switch (1). This will start vacuum operation.
3-
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
4-
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:
Check if the IEC plug is well connected.
1-
Check if the power switch (11) is on (green light on).
2-
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
3-
IEC of the machine.
The bag is not well sealed / Air come in the bag:
In winter season, the sealing bar can be charged in humidity, at first use start a complete vacuum/seal cycle with cover closed
1-
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°.
3-
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 vacuum/seal cycle can be done without problems. Good seal can be done only if the cover press correctly
the sealing bar and cover can press correctly only if a good vacuum level is reached
Check if the open part of the bag is clean; placing food inside the bag can leave some food residuals: the part of the bag to be
4-
sealed, must be properly clean for an effective sealing.
5-
Check if the food which is to be vacuum preserved is free of every thorns or spikes could pierce the bag.
Humidity of the food can damage the seal: check if food is correctly dried or use a double bag. Place food in a first bag, bend
6-
repeatedly the open part of the bag (Image 8) and put the first bag in a second one with the upper part to the bottom of the
second. You can have same vacuum but the humidity will remains in the first bag
Using rolls, the first seal must be done placing the open part of the roll on seal bar only avoiding to put in the vacuum chamber ;
7-
the appliance can correctly seal only if there is a correct vacuum level and the cover 4 press correctly on the sealing bar.
8-
Only seal cycle: place the open part of the bag on the sealing bar only and not in the vacuum chamber and make a complete
automatic vacuum/seal cycle to have a good seal
If the air comes into the bag in seal cycle, and after a correct vacuum cycle, the bag is damaged and must be changed.
9-
No vacuum in the bag:
1-
Check the open part of the bag is correctly placed in the vacuum chamber and between the black gasket.
Perform the tests "Internal functioning", "Cover and vacuum gasket" and "Bag test" to check the appliance.
2-
3-
Suction of liquids can damage the gasket of vacuum chamber reducing the vacuum possibility of the machine, check the gasket
and change if necessary.
The appliance is prepared for use RGV embossed bags of the same type as furnished with the machine, if used with different or
4-
other label bags the machine could not have same performances.
5-
In Summer period, when ambient temperature become high, or in case of continuous and intensive use, the residual heat of the
sealing bar could pre-seal the bag and prevents vacuum. Use potentiometer or electronic setting to reduce seal power, wait some
minutes and re-start working with new settings.
The unit does not seal with automatic cycle:
Perform the tests "Internal functioning", "Cover and vacuum gaskets" and "Bag test" to check the
1-
appliance.
2-
Start vacuum cycle and seal manually to verify the welding bar efficiency.
Set the appliance to "Automatic use" as described above;
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 can limit the vacuum reached inside the bag. Without wrinkles and folds you can have a correct cover closing
and the vacuum/seal cycle can be done automatically. Automatic seal can be done only if the cover press correctly the sealing
bar and cover can press correctly only if a good vacuum level is reached.
The unit does not reach a good vacuum level in the bag:
1-
Check if the open part of the bas is correctly placed and a there is correct free space between food
and machine.
Perform the tests "Internal functioning", "Cover and vacuum gasket" and "Bag test" to check the
2-
appliance.
3-
Check if the food which is to be vacuum preserved is free of every thorns or spikes could pierce the
bag.
4- The appliance is prepared for use RGV embossed bags of the same type as furnished with the machine, if used with different or
other label bags the machine may not have same performances.
