Installing the servo oxygen control system (option)

The oxygen control system is normally factory installed. To install the oxygen
control system in the field, refer to the assembly instructions provided with the
system.
6.6.1 Installing the oxygen sensor cells in the sensor module
The incubator uses 2 independent oxygen sensors to provide redundancy and
cross-checking. For this reason, the oxygen sensor cells must be installed at the
same time, and are therefore provided as a pair.
1 Open the 2 bags containing the new oxygen sensors, and expose the sensors to
air. Note the time.
The individual oxygen sensor cells are packaged in airtight bags. After
packaging, the sensor slowly consumes all the oxygen in the bag, and then
enters a "sleep" state. When the bag is opened, the sensor must "wake up"
before its operation can stabilize. Therefore, the sensor should be exposed to
room temperature air for at least 30 min before attempting calibration. If
possible, open the bags 24 hours before installation.
If the oxygen sensor has been exposed to extreme temperatures (e.g., >50 °C
(122 °F) or <0 °C (32 °F)), it might require up to 24 hours to return to normal
operation.
2 Switch off the incubator on/off switch.
3 Unplug the sensor module cable from the shell.
4 If present, unplug the scale cable and any skin temperature probe cables from
the sensor module.
5 Pull down the lock (A) on the sensor module (B) and slide the module out from
the hood until it stops.
