INSTALLATION
The ONE O2 monitor should be fitted adjacent to the gas source. The monitor should be
wall mounted by fixing firmly to a clean, dry, vertical surface using appropriate fixings.
When deciding where to position the monitor, consideration should be given to:
[i] whether the alarm lights and audible alarm can be easily seen and heard, and
[ii] whether the unit is placed so that it is monitoring the required area adequately.
Take care to ensure that the monitor is not installed above items such as work tops or other
equipment and cannot be obstructed or blocked-in by any item which may restrict the free
flow of air around the monitor.
The monitor should be located at a height appropriate for the monitoring conditions. For
oxygen deficiency applications where the inert gas has a relative density greater than air the
monitor should be positioned 1m above floor level. For inert gases with a relative density
lower than air (helium) the monitor should be positioned as high as practicable. For oxygen
enrichment applications the monitor should be positioned 1m above floor level.
The ONE O2 base unit monitors the surrounding air by natural convection and diffusion into
the oxygen sensor through the sensor filter in its base.
IT IS IMPORTANT TO ENSURE THAT THE SENSOR FILTER IS NEITHER COVERED NOR BLOCKED
and that
AIR CAN CIRCULATE FREELY AROUND THIS FILTER AND THE BASE OF THE UNIT.
The ONE O2 monitor must not be exposed to, immersed in or sprayed with water, rain,
solutions or other solvents.
