CYCLE COMPLETE

Indicates the user should:
• Refill the water pan with single distilled water no purer than 1 Mega OHM in preparation to return to normal
running.
Note: If Decon Cycle is run as routine maintenance, it is ok to reuse the HEPA filters
for the service life indicated in Section 10.
If contamination is an issue due to the room environment, HEPA filters can be replaced as necessary.
RESUME NORMAL OPERATION

Press the Exit button after fulfilling the on screen instructions
•
This puts the Incubator into normal run mode
•
CO
2
control resumes
•
Checking the calibration of the temperature sensor is recommended.
Follow the instructions in section 9.1 of the manual
DECON CYCLE NOTES:
•
Aborting the cycle:
To abort any phase of either the 95 or 145 decontamination cycles press the cancel button to step through the
different phases of the cycle that are described above. The cool down phase cannot be bypassed until
temperature reduces to the temperature set point. See cautions below.
•
In case of a power interruption, the heat up, drying & cool down phases will resume when power is restored.
The decon phase will reset to the beginning of the 3-hour cycle or if the temperature drops more than 10 ° it will
go back to the heat up phase then resume the cycle when decon temperature is reached.
•
It is considered normal for some odor to occur during the Decon Cycles.
This odor reduces with use of the Decon Cycle.
•
Some discoloration due to heat of the chamber and its components can be expected.
•
If decon temperature is not reached within the time allotted (set by the temp. Time Out option).
The Incubator will alarm and indicate an Alarm Status condition in the display.
•
If the inner glass door is opened during the Decon Cycle an alarm sounds and the Decon Door Open Alarm will
overtake the display telling the user to close the door.
•
Place Incubators 10" apart when placed side-by-side to enable running the heated Decon Cycle while
surrounding Incubators are in normal run mode.
USING THE 95 ° DECON CYCLE
The 95
°
C decontamination cycle is humidified to ensure that the contaminating agents are eradicated. The complete
cycle takes about 14 hours to run. (See graph for cycle phases). There is no need to recalibrate or remove the CO
2
IR
sensor since it is remote from the chamber.
OUTER DOOR MUST REMAIN CLOSED DURING THE DOCONTAMINATION CYCLE OR
IF TEMPERATURE IS OVER 55
°
.
THE DECONTAMINATION CYCLE WILL HEAT THE INCUBATOR INTERIOR SURFACES TO 95 ° C +.
CONTACT WITH ANY SURFACE INSIDE OF THE OUTER DOOR DURING THIS CYCLE CAN RESULT IN BURNS.
