monitor enclosure should be mounted in an area free of vibration and electrical
noise or interference. If possible, avoid areas with high temperatures or condensing humidity.
The oxygen monitor covers an area of approximately 692 square feet when mounted on a wall and
should be placed no more than 21 feet from potential leak sources such as gas lines, gas cylinders, or
any areas where a gas leak might be expected to occur. To ensure safety, the maximum distance
between two monitors mounted to the same wall, should
not
exceed 30 feet.

The transmitter and sensor should be installed in a location where gas leaks are likely to occur or
where released gases may accumulate. It should be mounted no closer than 12 inches above floor level.
Airflow within the monitored area, the characteristics of the gas (lighter or heavier than air), and the
position of workstations and personnel should all be considered in determining the most suitable
installation location.
