OWNER’S MANUAL
Pre-Cycle Error Messages (Before the ampoule is broken): The self test portion
of the cycle begins when the
START button is pressed and ends after the initial purg-
ing of the sterilization liner bag. Ethylene Oxide has not been released into the ster-
ilization liner bag during the self test. Therefore, it is safe to remove the sterilization
liner bag and its contents from the machine if needed. The self test screen is shown
below.
If you see this screen, the controller is indicating that the ventilation sensor, purge
sensor, ventilation pump and cooling fan are all operating correctly. If an abator is
attached to the sterilizer, it indicates that the abator pump is operating correctly as
well. The bottom line on this display indicates that the cooling fan is running at
100% of its nominal revolutions per minute (RPM).
6.1. VENT SENSOR FAILURE: Failure of the ventilation sensor during the self test
portion of the cycle will show the VENT SENSOR FAILURE message on the
screen. A vent sensor failure during the self test is often caused by a defective sensor.
In this instance, the sensor needs to be replaced.
6.2. PURGE SENSOR FAILURE: Failure of the purge sensor during the self test por-
tion of the cycle will show the PURGE SENSOR FAILURE message on the screen.
A purge sensor failure during the self test is often caused by a defective sensor. In
this instance, the sensor needs to be replaced.
6.3. PRESSURE SENSOR FAILURE: Failure of the pressure sensor during the self test
portion of the cycle will show the PRESSURE SENSOR FAILURE message on the
screen. A pressure sensor failure during the self test is often caused by a defective
sensor. In this instance, the sensor needs to be replaced.
6.4. VENT PUMP FAILURE: Failure of the ventilation pump during the self test potion
of the cycle will show the VENT PUMP FAILURE message on the screen.
Possible causes of VENT PUMP FAILURE during self test and remedies:
• The ventilation tubing has become disconnected inside the top cabinet. Reconnect
ventilation tubing.
• The ventilation vacuum pump has failed to generate the required vacuum. Replace
ventilation vacuum pump.
• The exhaust tubing from the ventilation pump is blocked. Remove obstruction.
