The pump sensor unit should be mounted at chest height with
the sample line travelling to the chosen target area at either
maximum height for lighter than air gases or minimum low
level (100mm) for heavier than air gases. A filter (Part no. 008-
212) should be attached to the pipe end where high levels of
particulates may be present.
