4.5. 2nd VACUUM PHASE
This phase of the cycle allows the chamber pressure to drop below the value of 1.00 bar reached during the 1
st
PRESSURE RISE, by discharging steam through solenoid valve EV1 and draining condensate through the solenoid
valve EV3 connected to the chamber filter.
When the value of 0.10 bar is reached, with the activation of solenoid valve EV4, the pressure continues dropping
until reaching the value of - 0.80, by means of the vacuum pump, already activated at the beginning of the 2
nd
VACUUM PHASE.
In order to make it easier to reach the value of - 0.80 bar, also solenoid valve EV2 is activated for 5”.
