Decontamination Cycle (DECN301)
Series 7400, 7401, 7402 and 7403 incubators can be equipped with an optional 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.
The DECN301 option requires a humidity water source. The water can be provided to
the incubator using the following methods:
 For units with optional humidity control (HUMD304 & HUMD307), be sure there is
an adequate water supply going to the incubator
 For units with a water pan (Model 7400, HUMD305, & HUMD306): Fill the water
pan with 2 liters of water and place in the chamber
 For all other units, plug incubator floor drain and fill with 2 liters of water.
Before initiating a decontamination cycle, the following steps must be completed:
1) Power down the incubator.
2) Remove all samples, products, equipment, etc … from the incubator.
3) If the unit is equipped with an inner door kit, remove the inner doors and lay them
on the incubator shelving during 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.
