3.2 Installation of the O2 Sensor
Correct placement of the O2 Sensor
The O2 sensor should be placed in the room where there is a risk for unsafe oxygen concentration –
this would be at the distribution points of the nitrogen, nitrogen generator or nitrogen tank as well as
mixed gas with nitrogen. Please observe, this does not necessarily have to be where the asphyxiant
gas is stored, for example when it is stored outside and the gas is routed into the building via pipes.
It is also VERY IMPORTANT to be aware that the danger always is relative to how much asphyxiant
gas is used and stored in relationship to the volume of the room in question.
NOTE: If the room has only mechanical ventilation, it should have a sensor.
Installation of the O2 Sensor
The O2 sensor should be installed at breathing height, between 150-180 cm/5-6 feet from the floor.
Try to find an installation position where the unit is least likely to be damaged. Mount the O2 sensor
with supplied mounting screws.
