Maintenance and Troubleshooting
AUTO-DIAGNOSIS TESTS
INTERNAL COMPONENT OPERATION
• With the cover open, press the start button and close the air press with a finger.
• If the hand on the vacuum gauge reaches red (and/or the red led switches on) and sealing automatically
starts, internal operation is correct.
• If the hand on the vacuum gauge reaches red (and/or the red led switches on) but sealing does not
automatically start, you need to set the machine for automatic operation and try again.
• If the hand on the vacuum gauge does not reach red (and/or the red light does not switch on) the vacuum
pump is damaged or there is an air leak in the internal tubes circuit - contact a support centre for repair.
OPERATION OF THE COVER AND GASKETS ON THE VACUUM CHAMBER
• Close the cover on the machine (without inserting the bag), press the start button and exert light pressure
on the cover to start the automatic cycle.
• If the hand on the vacuum gauge reaches red (and/or the red led switches on) and sealing automatically
starts, machine operation is correct.
• If the hand on the vacuum gauge reaches red (and/or the red led switches on) but sealing does not
automatically start, you need to set the machine for automatic operation and try again.
• If the hand on the vacuum gauge does not reach red (and/or the red light does not switch on), you need to
check the chamber gaskets of the vacuum (clean the gaskets or replace them) and try again.
BAG INSERTION TEST
•
Lift the cover.
•
Position the open end of the empty bag in the chamber of the vacuum, between the gaskets in the vacuum
chamber.
•
Lower the cover, press the start button and exert light pressure on the cover to start the automatic cycle.
• If the hand on the vacuum gauge reaches red (and/or the red led switches on) and sealing automatically
starts, machine operation is correct.
• If the hand on the vacuum gauge reaches red (and/or the red led switches on) but sealing does not
automatically start, you need to set the machine for automatic operation and try again.
Using these tests, you can check machine operation and you get correct insertion of the bag in the vacuum
chamber. Correct packaging is only obtained if enough free space is left between the product and the machine
(approx. 5 cm. are usually enough) provided the bag can be inserted well laid between the gaskets of the
vacuum chamber, without creating folds that could create air leaks, reducing the vacuum level and the quality
of sealing.
THE MACHINE DOES NOT START
•
Check you have correctly inserted the plug in the electricity socket and the press is powered.
THE BAG IS NOT WELL SEALED/AIR IS ENTERING THE BAG
• During the winter period, and in the presence of extreme temperature changes, the sealing bar can fill
with humidity. On first start-up of the cold machine you should execute a completed vacuum/sealing cycle
with the cover closed (also without a bag) to reset the machine and stabilise the temperature and humidity
conditions. To avoid problems also on first use, the appliance must be kept in a dry place at a temperature
