EO Abator Operation and Installation Manual

Operating Instructions for 5XL/8XL and GS Series Steri-Vac Sterilizers
1. Auto-On: The Abator is turned on automatically by the sterilizer.
Note:
The Abator will be automatically turned on if the power to the Steri-Vac is turned off, or the communication
connections between the sterilizer and Abator are lost.
2. Abator system ready indicator (green) on indicator panel illuminates when the Abator is ready to process EO. With
ambient temperature of 21ºC (70ºC), the indicator should illuminate within 40 minutes. If the Abator system ready
indicator light does not illuminate within this time frame, observe the fault lights on the control panel and correct
problem before operating unit.
3. End of cycle. The Abator system is stopped automatically by the sterilizer. A timer lets the blower run 30 minutes to
cool the Abator before shutting down.
4. When performing maintenance or when the over temperature indicator is on, the system should be shut down.
When shutting down the Abator, make sure the sterilizer is not venting EO and that the Abator is not processing
EO. In an emergency situation, the Abator can be shut down at any time. To shut down the system in an emergency,
have an authorized person switch the external disconnect and main circuit breaker in the control panel to the off
position.
Typical Abator System Cycle for 5XL/8XL and GS Series Steri-Vac Sterilizers:
After the sterilizer is loaded, the sterilizer door is closed and the cycle is started. The Abator system starts automatically.
After approximately 40 minutes, the Abator ready light illuminates indicating the Abator is ready to begin processing EO.
When the sterilizer purges EO from the cycle, it enters the Abator through the EO inlet where it is internally fed to the
catalytic cell. The temperature of the catalytic cell increases proportionately to the amount of EO fed into the Abator.
After the sterilizer cycle is complete and the abatement of EO is halted by the sterilizer, the Abator continues to run for
30 minutes to cool the system down before shutting off. Ambient air flows through the Abator and cools the catalytic
cell.
