OPERATIVE CYCLE
PHASE 1: FIRST VACUUM AND WATER INLET (VACUUM 1)
As a first operation, the autoclave activates the vacuum pump (F) and the status of EV5
change in ON. Thanks to the change of EV3 in ON, the air is suctioned from the chamber of
sterilization. During the phase of reaching of vacuum, EV6 activates and deactivates for
cooling and for cleaning the surface of the membranes of the vacuum pump (the average
time of this phase is about 2 / 3 minutes).
EV2 EV3 EV4 EV5 EV6 EV7
ON (3 times at intervals -0.2bar /
OFF ON OFF ON OFF
-0.4bar / -0.6bar)
Once the negative pressure of -0.90 bar (-0.86 bar for the 24L) is reached, EV3 closes (off),
the vacuum pump stops working and the valve EV4 opens (on) to enable the inlet of water
into the chamber from the clean water tank (E). The quantity of water is read by the
flowmeter; when the correct quantity of water is reached, EV4 closes (off).
