6.2.3 Mounting EC150 without CSAT3A
The instructions for mounting the EC150 without the CSAT3A should
generally follow those in Section 6.2.2, Mounting EC150 with optional
CSAT3A, but requires the use of a different mounting bracket as described
below and in Section 6.2, Mounting Analyzer to Support Hardware.
1. Bolt the EC150 head-only mounting bracket (pn 26785; see FIGURE
6-1) to the CM250 leveling mount (pn 26559).
2. Mount the EC150 gas analyzer head to the EC150 head-only
mounting bracket and follow the steps outlined in Section 6.2.2,
Mounting EC150 with Optional CSAT3A, for preassembly.
3. Mount this assembly to the end of the crossarm by fitting the leveling
mount over the end of the crossarm.
4. Tighten the set screws on the leveling mount.
5. If the assembly is not level, slightly loosen the bolt that holds the
mounting bracket on the leveling mount and adjust the assembly.
Retighten the bolt.
