11511 Standby Stage
Once programmed aeration time elapses, the system will proceed from the Aeration stage to Standby In this stage, the system will perform either pulsed or continuous room temperature
aeration If this stage was reached upon completion of programmed aeration, without any errors, the system will perform pulsed room temperature aeration (Figure 50) If this stage was reached
following specified error recovery modes, the system will perform continuous room temperature aeration
Like the Aeration stage, the Standby stage admits air into the chamber through a filter with a series of timed vacuum draws Standby stage will reduce the potential buildup of residual EO in
the chamber before the chamber door is opened and the load is removed
The Standby stage is preprogrammed and cannot be changed by the user.
Standby stage stops when the
chamber door is opened and the red Stop button is pressed
The Standby stage should be considered and evaluated during:
•
user’s facility management exposure assessments
•
developing and validating cycles for sterilization
•
before implementing facility standard operating procedures (SOPs) for the 3M™ Steri‑Vac™ Sterilizer/Aerator GSX Series

11512 Estimated Total Cycle Time
The 3M™ Cycle Programmer will estimate the total cycle time with each set‑point change The estimated total cycle time includes programmed Aeration stage
The connection of a
3M™ Abator will add an estimated 25‑50 minutes to the total cycle time during the EO Removal stage which is not included in the 3M Cycle Programmer estimate.
