Handle the IRGASON carefully. The optical source may
be damaged by rough handling, especially while the
analyzer is powered.
6. If the assembly is not level, slightly loosen the bolt that holds the
mounting bracket on the boom adapter and adjust the assembly until the
leveling bubble on top of the IRGASON block is within the bullseye.
Retighten the bolt.
7. Attach the EC100 enclosure to the mast, tripod leg, or other part of the
mounting structure. To do this, attach the EC100-enclosure mounting
bracket (pn 26604) to the pipe by loosely tightening the u-bolts around the
pipe. The u-bolts are found in the mesh pocket inside the EC100
enclosure. If the pipe does not run vertically (for example, if the enclosure
is being attached to a leg of a tripod), rotate the bracket to the side of the
pipe. The enclosure must hang upright. Make angle adjustments as needed
by loosening the four nuts and rotating the bracket plates relative to one
another. If the necessary angle cannot be achieved in the given orientation,
the four nuts may be removed and the top plate indexed by 90° to allow
the bracket to travel in the other direction (see FIGURE 6-2 ). Once
adjusted, tighten all the nuts. Finally, attach the EC100 enclosure to the
bracket by loosening the bolts on the back of the enclosure, hanging the
enclosure on the mounting bracket (it should slide into place and be able to
securely hang from the bracket), and tightening the bolts (see FIGURE
6-3 ).
