• The boiling point of the liquid is decreased as the pressure inside the vacuum chamber decre-
ases. Water at 23.4 absolute mbar (equal to a vacuum of 97.66%) boils at 20°C. The formation
of bubbles in the bag indicates the formation of steam. The liquid must not leak in any way,
so as to prevent it from being accidentally inhaled.
• at first start-up make sure you have performed the calibration of the vacuum sensor (see Chap. 7 - pt.
1: press the vaC/GaS key for 4 seconds with the machine on. Lower the lid to start the calibration
and wait until the cycle ends).
• When work is complete, detach the piston by pushing it toward the rear and lower the lid to the resting
position. This protects the vacuum chamber from dust and dirt.
1) Open the lid. Lift the lid all the way and attach the piston, moving it forward. (Fig. 1-2-3).
2) Insert the inclined surface for liquids (optional). Remove all the panels and insert the inclined surface
