WaRNINg! With lowering of the pressure inside the vacuum chamber, the liquid boiling
point is lowered. Water at 23.4 absolute mbar (corresponding to a vacuum of 97.66%) boils
at 20°C. Steam formation is evident from the bubbles forming inside the bag. In this case,
press the SToP button and reset the vaC parameter to such a level as to prevent bubble
formation.
The operation is carried out with a help of an inclined work top for liquids
1) Lower the lid holder: the plexiglas cover of the chamber opens.
2) Remove all the insertion plates and insert the inclined work top
the sealing bar and sliding retainer
3) Insert the bag containing the liquid to be packed inside the chamber, making sure that it is only half-filled
(1/2) (fig. 1). Place it centered on the sealing bar, so that the open end projects by about 20mm beyond the
bar.
4) Repeat the operations described in the "VACUUM CREATION/PROGRAMMING" paragraphs, adjusting the
vacuum time to such a value as to avoid boiling.
