To install the analyzer:
Non-Shelter Installations
In a suitable indoor, accessible location as close as possible to the sample gas
extraction point, install the analyzer on a vibration-free wall or instrument rack.
Ensure appropriate clearances are made to allow for heat dissipation and ac-
cess for servicing the analyzer. Clearances must be at least:
- 150 mm
- 75 mm (3") at top and bottom of backpan
- 900 mm (36")
Shelter Installations
In a suitable location as close as possible to the sample point, install the ana-
lyzer in a vibration-free location.

Minimize sample response time.
Minimize the amount of sample gas required for purging the Measuring
Cell and sample system.
Reduce the workload of the filter.
Minimize heating requirements (for Sample Line, if required).
Do not install the Heatsink/Measuring Cell Assembly until after the
analyzer has been installed (see "Installing the Heatsink/Measuring
Cell Assembly."
(6") on each side of backpan
in front of analyzer
For each installation method, AMETEK recommends mounting the
analyzer higher than the process pipe, since liquids can occasionally
appear in the process stream and in the Sample Line. This will allow
these liquids in the Sample Line to drain back into the process pipe.
