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
5-
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 sealed, must be
properly clean for an effective sealing.
6-
Check if the food which is to be vacuum preserved is free of every thorns or spikes could pierce the bag.
7-
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 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 (Images 9 and 10). You can
have same vacuum but the humidity will remains in the first bag (Image 11)
8-
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 (Image 2); the
appliance can correctly seal only if there is a correct vacuum level and the cover 4 press correctly on the sealing bar.
9-
Only seal cycle: place the open part of the bag as per Image 2, on the sealing bar only and not in the vacuum chamber and make a complete
automatic vacuum/seal cycle to have a good seal.
10-
If the air comes into the bag in seal cycle, and after a correct vacuum cycle, the bag is damaged and must be changed.
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. (Image 1)
2-
Perform the tests “Internal functioning”, “Cover and vacuum gasket” and “Bag test” to check the appliance.
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.
4-
The appliance is prepared for use Reber embossed bags of the same type as furnished with the machine, if used with different or 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:
1-
Perform the tests “Internal functioning”, “Cover and vacuum gaskets” and “Bag test” to check the appliance. 2-
Start vacuum cycle and seal manually to verify the welding bar efficiency.
3-
Set the appliance to “Automatic use” as described above;
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 as per Image 1 and a there is correct free space between
food and machine.
2-
Perform the tests “Internal functioning”, “Cover and vacuum gasket” and “Bag test” to check the 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 Reber 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.
