5.3 Run sterilization program
5.3.1 THREE TIMES PRE-VACUUM PROGRAM（HOLLOW PRION COTTON）
Click “start”botton of Fig.5.3-1 interface,the sterilization program will be started and enter into Fig.5.3-2 or Fig.5.3-3 interface.
When temperature of heating coil(T3) rised and less than 100℃,Screen will show Fig.5.3-2 interface (the heating coil pre-heating stage).
When temperature of heating coil(T3) rised and over than 100℃,Screen will show Fig.5.3-3 interface (the first times pre-vacuum stage).
Click “ ”to check T3 temperature.(Fig.5.3-4)
5.3.1.1.THE FIRST TIMES PRE-VACUUM STAGE(Fig.5.3-3)
when the T3 temperature over than 100℃,the sterilizer will start evacuating and the control system will open the vacuum pump
solenoid valve(Ev4).LCD shows “00:03:59”time countdown.If the vacuum value reaches Pv value ahead of time, sterilization
program goes into heating stage in advance.
ATTENTION:If the vacuum value of less than Pv (factory default setting Pv=-0.800bar) in “00:03:59”, there will be with alarm E12.

5.3.1.2.THE FIRST TIMES HEATING STAGE(Fig.5.3-5)
When the vacuum value reachs Pv value,the contrl system will open the water pump-solenoid valve(Ev2).The steam generator start to inject the
steam into chamber.The temperatures(T1 and T2) and pressure inside the chamber will be rised at the same time.
5.3.1.3.THE FIRST TIMES EXHAUST STAGE(Fig.5.3-6)
When the pressure inside the chamber reachs 1.100bar,the control system will open the exhaust-solenoid valve(Ev1) for exhausting untill pressure
downs to P=0.000bar.LCD shows “00:01:29”time countdown.
5.3.1.4.THE SECOND TIMES PRE-VACUUM STAGE(Fig.5.3-7)
When the pressure inside the chamber downs to 0.000bar,the control system will open the vacuum pump-solenoid valve(Ev4) and start evacuating.
LCD shows “00:03:59”time countdown.it the vacuum value reaches -0.700bar ahead of time, sterilization program goes into heating stage in advance.
