OWNER’S MANUAL
☺ HINT: The AN74 i/ix can be used for extended aeration. A count-up timer will keep
track of the time that has passed since the standard cycle was completed. After the
regular cycle is finished, the sterilizer will continue to ventilate and purge the liner bag
until: (1) the door is opened; and (2) the EXIT button is pressed. This will turn off both
pumps and end the cycle. If the door is opened and closed and the EXIT button is not
pressed, the two pumps will continue to ventilate and purge the liner bag and cabinet.
• Extended aeration can also take place outside of the sterilizer. In this case, aeration
should take place in a well-ventilated area that provides at least 10 fresh air
exchanges per hour so that high concentrations of gas will not build up while
aerating.
E. Safety Precautions
1) Ethylene Oxide Safety
• Sterilization liner bags should never be reused because they may have a puncture or
tear.
• DANGER! Do not allow open flame or sparks near the sterilizer during the
sterilization cycle because ethylene oxide gas is highly flammable in concentrations
above 3.0% (30,000 ppm).
• The 12 and 24-hour sterilization cycles both end with a 2-hour purge cycle, which
flushes fresh air around the products in the sterilization load.
• The sterilization liner bag must be purged for 2 hours before the sterilized items are
removed to prevent the operator from being exposed to more than the OSHA
permitted level of 5.0 ppm in a 15-minute time period (STEL) while the sterilizer is
being unloaded.
• Personnel exposure to ethylene oxide can be monitored by using the personal
exposure badges, such as the Andersen AN93 AirScan ® Badges. The AN93 AirScan
Kit has both STEL and TWA badges. EO exposure levels should be checked upon
installation of the sterilizer. We recommend that exposure testing be performed on an
annual basis.
• CAUTION. If you come in contact with liquid Anprolene, you should immediately
wash the affected area with water thoroughly for at least 15 minutes and obtain
medical attention.
2) Malfunctions and Power Failures
• In the event of a purge pump failure, the vent pump will continue to ventilate the
interior of the cabinet, exhausting gas as it diffuses through the liner bag. A PURGE
PUMP FAILURE error message will be displayed, and the sterilizer will add 24
hours of aeration before the display indicates that you may remove your products. (If
this happens, please call Customer Service for assistance.)
• In the event of a vent pump failure, the cycle will be aborted, and the purge pump
will evacuate the liner bag of any remaining gas. (If this happens, please call
Customer Service for assistance.)
