Replacing the hydrogen sulfide sensor

Danger of poisoning
The replacement of the sensor module represents interference in the gas path. The sample
gas circulating therein may contain toxic components that lead to death in certain
concentrations.
To ensure that the sample gas path is free of toxic material when replacing the sensor
module, the gas path must be flushed with ambient air or nitrogen for a period of about 10
minutes before performing the task.
Danger of electric shock
The device will be open when the sensor is being replaced. This means present dangerous
contact voltage will be present, which can lead to electric shock.
For this reason, the sensor module may only be replaced when power is off.
