Failure to remove the sensor will result in
damage to the sensor and will not be covered
by warranty.
Do not immerse the sensor in any type of
cleaner as damage to the sensor may occur.
Decontamination Cycle
The 7404-10 incubator is equipped with a moist heat decontamination cycle. The
purpose of the cycle is to eliminate common microbial contamination in your incubator
and extend the time between manual cleaning cycles. The decontamination cycle is
intended to be used as a reactive system to eliminate contamination. It is not necessary
to run the cycle at a fixed time interval.
Before initiating a decontamination cycle, the following steps must be completed:
1) Remove all samples, products, equipment, etc … from the incubator.
2) Power down the incubator.
3) If the unit is equipped with an internal outlet remove outlet from incubator before
starting the decontamination cycle.
4) Locate the removable sensor access plate in the rear plenum of the incubator.
Remove the plate by sliding the fasteners down.
5) With power off, remove the infrared CO2 sensor by unscrewing the connector on
the rear of the CO2 sensor. The sensor unscrews where the orange cable meets
the gray sensor housing.
6) Insert the orange cable into the grommet where the sensor was removed so that it
is easily accessed when the sensor is replaced following the decon cycle.
7) Replace the CO2 sensor plate and turn the incubator power switch back on.
8) The infrared CO2 sensor can be disinfected using isopropanol. Spray the cleaner
on a soft clean cloth and wipe the sensor.
