The Vacuum Test program is run with the sterilization chamber empty, except for the trays and
their supports.
RUN THE VACUUM TEST AS THE FIRST CYCLE AFTER POWERING-ON THE EQUIPMENT.
To avoid the heating of the sterilization chamber influencing the variation of the vacuum value
measured during the Vacuum Test, the system is programmed to prevent running this test
when the temperature sensors of the sterilization chamber show a value higher than 50° C.
If you try to start the program with a higher temperature than indicated above, the display will
read:
WARNING!
PT1 OVERHEATING
- 0.80 bar
After a short time, the device will automatically return to STAND-B Y mode, ready for use.
TO RAPIDLY LOWER THE TEMPERATURE OF THE CHAMBER LEAVE THE STERILIZER'S
DOOR OPEN UNTIL THE CORRECT TEMPERATURE IS REACHED.
Close the door and start the program with the S T AR T key.
IN ADDITION, THE EQUIPMENT CHECKS THE PRINTER PAPER PRESENCE (OPTION) A N D, IF
