(3)Descriptions of process operation
G)Set the exhaust tank to the unit.
Fill the exhaust tank with water up to the "LOW" level and set the tank to the unit.
~Turn
"ION"
the power switch.
For the first 4 sec., the boiling point setting temperatura is displayed on the IDigital Display II and the bar
display "- - -" appears on the IDigital Display III ' and then the set temperature, set time or the cycle is
displayed.
Press down the handlij and pull the Imovable handleltoward you to open the cover. Fill the chamber with
water until the end of the water level metal of the heater cover is immersed in the water. Put object(s) to be
sterilized in the attached stainless-steel basket, set it in the chamber and close the cover.
@Heating process (Process monitor lamp: "Heating" flickers.)
After checking the detail of the cycle and settings, press the ISTART buttonl. Then, "Beep Beep" sound is
heard and the power to the
~terilization heate~
is turned ON to heat the heating water and generate steam.
At this time, the air in the chamber is driven out by steam. The steam at that time is discharged into the
exhaust tank where it is condensed to water. Also, excess steam which could not be condensed enough
flows into the back side exhaust tank at the back side of the unit.
After the completion of air exhausting process, closing of the
c-x-;h:-:a-us-:-;t-v-::a~lvCle
fills the chamber with steam
and raises the pressure.
After starting, the COVER LOCK lam lights up and the cover can not be opened
due to interlock function.
@Sterilization process (Process monitor lamp: "Sterilization" flickers.)
When the temperature in the chamber reaches the sterilization temperature, the Isterilization
time~
starts
working. During sterilization, the tern erature in the chamber is detected by the lateral thermistor (THI) and
the power supply to the sterilization heate is controlled by microcomputer. The temperature can be set
every i'C between 115'C and 135'C.
When the set sterilization time elapses, the sterilization process ends and goes to the next exhaust process.
@Melting process (Process monitor lamp: "Melting" flickers.)
This process is for melting culture medium, etc. The temperature in the chamber is detected by the lateral
thermistor (TH I) and the power supply to the ~terilization heate~ is controlled by microcomputer. The
temperature can be set every I'C between 60·C and 114"C.
@Exhaust process (Process monitor lamp: "Exhaust" flickers.)
<For INSUMENT STERI>
By shutting down the power supply to the ~terilization heate~ and opening the lexhaust valvij, steam in the
chamber is discharged into the exhaust tank to perform cooling.
This process is to be performed when the sterilization object is instrument, etc.
<For other than INSUMENT STERI>
Shut down the power supply to the
~terilization heate~
and keep the lexhaust valve
~Iosed
so that the
temperature in the chamber is cooled naturally. When the tern erature in the chamber lowers down to the
preset exhaust temperature (initial value or boiling pint), th exhaust valv opens.
This process is performed when the sterilization object is liquid such as culture medium, etc.
The
sterilization object is prevented from spilling out due to burst boiling.
(l)Keep-warm process (Process monitor lamp: "Keep Work" flickers.)
The temperature of sterilization object such as melted culture medium or sterilized culture medium can be
set and maintained every I·C between 45"C and 60·C and the sterilization object can be kept warm for 72
hours. (The keep-warm process can be completed by pressing the !lTOP buttonl.) The temperature in the
chamber is detected by the lateral thermistor (TH I) and the power supply to the Isterilization
heate~
is
controlled by microcomputer.
@Completion process
<LIQUID STERI cycle/INSTRUMENT STERI cycle> (Process monitor lamp: "Completion" flickers.)
When the temperature in the chamber lowers down to a certain level, the buzzer sound "Beep" is issued ten
times, and the bar display"- - -" appears on the IDigital Display III to inform the completion of operation.
<Sterilization/Keep-warm cycle· Melting/Keep-warm cycle> (Process monitor lamp: "Completion" flickers.)
After the completion of keep-warm cycle, the buzzer sound "Beep" is issued ten times, and the bar display
"- - -" appears on thel Digital Display III to inform the completion of operation.
